Description


FIELD OF THE INVENTION

[0002] The present invention relates generally to a combination dump and spreader apparatus which, when mounted onto a vehicle chassis, provides for selective dumping and spreading of material from the apparatus, advantageously granular material such as sand, salt and the like, onto surfaces such as roadways.



BACKGROUND OF THE INVENTION

[0003] Many types of vehicles are available with an apparatus mounted thereon which provide for both the dumping and spreading of material, such as sand, salt, gravel, asphalt and the like, onto a surface. One type of apparatus which provides this dual functionality is commonly referred to as a combination body. Combination bodies are so named because they provide, in combination, both dumping and spreading functions. Examples of combination bodies are provided by U.S. Pat. Nos. 5,400,974 and 5,772,389.


[0004] In general, combination bodies are pivotally mounted onto the chassis of a vehicle, typically a truck chassis. Although the bodies can be mounted so as to pivot in one or more directions, the most common mounting arrangement provides a hinge mechanism on the rear of the body and a hydraulic cylinder on the front or the rear of the body, wherein movement of the cylinder causes the body to pivot about the rear hinge mechanism. This pivoting movement provides the bodies with the ability to dump material from the rear of the bodies.


[0005] Conventional combination bodies further include a conveyor system that transports material residing within the body out of the body and into one or more spreaders mounted on the exterior of the vehicle. Such conveyor systems typically include a longitudinal endless conveyor located within the body that transports the material from the front to the rear of the body or, alternatively, from the rear to the front of the body. The former situation typically results in a deposit of the material into a conventional spreader mounted on the rear of the vehicle. In the latter situation, however, the material is transported out of the front of the body, through a gate, and onto another part of the conveyor system—a cross conveyor—mounted on the chassis, and located adjacent the front of the body. The cross conveyor in turn transports the material laterally to the sides of the vehicle, and deposits the material into conventional side-mounted spreaders.


[0006] Conventional combination bodies also include a tailgate that covers the rear of the body. As the tailgate is pivotally mounted at the upper corners of the body, the tailgate can pivot into an open position when it is desired to utilize the dumping functionality of the body. Certain tailgates are also pivotally mounted at the lower corners of the bodies, allowing the tailgate to be lowered to assist in cleaning and rear loading.


[0007] The tailgates of those conventional bodies further include at least one opening therethrough, with a second opening often provided in the front of the body. The openings provide a means by which the material, upon transport by the endless conveyor, can be expelled from the front and the rear of the body. When spreading is desired, one or both of the openings can be selectively opened or closed by operation of a feed gate mounted so as to cover the opening. The feed gate further provides a means for metering the flow of material through the opening, and into the cross conveyor or the rear-mounted spreader. Upon being expelled from the body through the tailgate opening, the material is directed into the rear spreader at least in part by a cover affixed to the tailgate.


[0008] Various cover designs have been utilized in combination bodies. One common type extends forward, into the body itself, and is designed to collapse when the tailgate is lowered. This type of cover, however, has heretofore only been used in bodies wherein the conveyor resides completely within the confines of the body. Another type of cover extends rearwardly from and is affixed to the tailgate. This cover, utilized in bodies wherein the endless conveyor extends rearward of the tailgate, is located above and adjacent to the tailgate opening, and is permanently affixed in this position.


[0009] While existing combination dump and spreader bodies provide many desirable features and advantages, there remain certain problems with these combination bodies. For example, spreaders are often provided to complement the spreading feature available in a combination body. The spreaders are typically mounted to the chassis. The mounting of the spreaders can be cumbersome for a dealer to perform. Furthermore, the spreader can be difficult to adjust once it has been mounted. In addition, a feed gate assembly can be provided to selectively control the movement of materials from the body. In use, the feed gate assembly undergoes considerable stress, which can cause deformation in the assembly.


[0010] In view of the foregoing, there exist various needs in the art. One such need is for a combination body which provides an easily mounted and readily adjustable spreader. Another need is for a combination body having a stronger feed gate assembly that can more ably withstand the forces to which it is subjected during operation.



SUMMARY OF THE INVENTION

[0011] The present invention addresses the foregoing and other needs by providing a combination body for selectively dumping and spreading materials. There is provided a vehicle including, at least, a chassis and a combination body for selectively dumping and spreading materials. The body is pivotably secured to the chassis at a hinge and is comprised of front and rear ends and first and second side walls. A hoist is provided which extends between the body and the chassis for pivoting the body about the hinge. A conveyor assembly is also included, which comprises an endless conveyor disposed between the side walls and extending beyond the rear end of the body. A tailgate is pivotably connected to the rear end of the body and has an opening therein to permit material to be transported therethrough by the endless conveyor.


[0012] In one aspect of the present invention, a feed gate assembly for selectively covering the opening of the tailgate is provided. The feed gate assembly comprises first and second support members mounted to the tailgate. A handle is rotatably mounted to the first and second support members. A bailment depends from the handle. The bailment is pivotally mounted to a cover plate, which is movable between a closed position and an open position. The bailment has first and second arms “in close proximity” to the first and second support members, respectively.


[0013] In another aspect of the present invention, the conveyor assembly further comprises a cross conveyor located adjacent the front end of the body. The endless conveyor is operable to selectively transport material from the body through the opening of the front end of the body to the cross conveyor. A feed gate assembly for selectively covering the opening of the front end of the body is provided. The feed gate assembly comprises first and second support members mounted to the front end of the body. A handle is rotatably mounted to the first and second support members. A bailment depends from the handle. The bailment is pivotally mounted to a cover plate, which is movable between a closed position and an open position. The bailment has first and second arms in close proximity to the first and second support members, respectively.


[0014] In a further aspect of the invention, the vehicle includes a tailgate pivotably connected to the rear end of the body. The tailgate has an opening therein to permit material to be transported therethrough by the endless conveyor. A conveyor cover assembly is provided that includes a cover and a mounting member. The cover has front and rear ends. The front end of the cover is removably mounted to the front end of the body. The rear end of the cover extends rearwardly from the tailgate. The mounting member is secured to the body adjacent the rear end of the body. The rear end of the cover is removably mounted to the mounting member. The cover is configured to completely cover the endless conveyor along the length thereof.


[0015] In another aspect of the invention, the vehicle includes a diverter chute that is operably arranged with the conveyor assembly to receive materials from the conveyor assembly. The chute includes a body that defines a passageway and a panel that is movable between a first position and a second position. The panel allows material to move through the chute to the spreader when the panel is in the first position. The panel prevents material from moving through the chute when the panel is in the second position.


[0016] In yet another aspect of the invention, the vehicle includes a spreader for selectively spreading materials that is adjustably mounted to the vehicle and cooperatively arranged with the conveyor assembly to receive materials. The spreader is selectively movable along a first axis, a second axis, and a third axis. The hoist can pivot the body about the hinge between first and second positions. The spreader can include a disk, which defines a first spreader plane when the body is in the first position. Advantageously, the spreader can be pivotally mounted with respect to the body such that the disk defines a second spreader plane when the body is in the second position wherein the second spreader plane is substantially parallel to the first spreader plane.


[0017] Advantageously, a recess is defined by at least one of the first and second side walls. The recess is configured to accommodate at least one of a storage box and a storage tank. The recess has a recess length at least over fifty percent of the body length.


[0018] In a further aspect of the invention, the vehicle includes a spreader for selectively spreading materials. The spreader is mounted to the chassis. A chute is operably arranged with the conveyor assembly to receive materials and direct materials to the spreader. The chute is mounted to the body.


[0019] In another aspect of the invention, the conveyor assembly includes a cross conveyor located adjacent the front end of the body. A spreader for selectively spreading materials is cooperatively arranged with the conveyor assembly to receive materials. The spreader is adjustably mounted to the chassis such that the spreader is rotatable about a first axis.


[0020] These and other objects and advantages, as well as additional inventive features, of the present invention will become apparent to one of ordinary skill in the art upon reading the detailed description, in conjunction with the accompanying drawings, provided herein.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0043] Turning now to the drawings, there is shown in FIG. 1 an illustrative vehicle 20 including a combined dump and spreader apparatus, also known as a combination body, for dumping and spreading materials in accordance with the present invention. The present inventive vehicle shown and described herein improves upon the vehicle shown and described in U.S. patent application Ser. No. 09/256,053, filed Feb. 23, 1999, and entitled “Combination Dump And Spreader Apparatus,” which is incorporated herein by reference in its entirety.


[0044] Referring to FIGS. 1-3, the vehicle 20 includes a chassis 22 and a combination body 24 for holding materials and for selectively dumping and spreading materials. The body 24 is pivotally mounted to the chassis 22 at a hinge 26. The body 24 includes a front end 30 having an opening 32, a rear end 34, and first and second side walls 36, 38. A hoist 40 is provided which extends between the body 24 and the chassis 22 for pivoting the body about the hinge 26.


[0045] Referring to FIGS. 1 and 2, a conveyor assembly 50 for selectively conveying materials from the body 24 is also included. The conveyor assembly 50 includes an endless conveyor 52 disposed between the side walls 36, 38 of the body 24 and extending along the length of the body 24 beyond the rear end 34 of the body 24. The endless conveyor 52 can selectively transport material from the body 24 out the rear end 34 and from the body 24 out the opening 32 of the front end 30. The endless conveyor 52 is similar in construction and operation to the endless conveyor shown and described in U.S. patent application Ser. No. 09/256,053. It will be understood that the endless conveyor 52 can be provided in a variety of configurations, including, for example, but not limited to, an auger.


[0046] A tailgate 60 is pivotally connected to the rear end 34 of the body 24 and has an opening 62 therein to permit material to be transported therethrough by the endless conveyor 52. A rear feed gate assembly 70 for selectively covering the opening 62 of the tailgate 60 is provided. A rotatable tailgate cover 71 is provided to assist in properly positioning the material on the endless conveyor 52 as it leaves the opening 62 of the tailgate 60 and in directing the material downwardly onto a rear diverter chute 72. The cover 71 is pivotally mounted to the tailgate 60. The cover 71 extends at least partially over the portion of the endless conveyor 52 that extends beyond the tailgate 60.


[0047] The rear diverter chute 72 is operably arranged with the conveyor assembly 50 to receive materials from the endless conveyor 52 and to direct the materials to a rear spreader 74 for selectively spreading materials. A first spreader mounting assembly 76 adjustably mounts the rear spreader 74 to the vehicle 20. The rear spreader 74 is cooperatively arranged with the conveyor assembly 50 to receive materials.


[0048] The conveyor assembly 50 further includes a cross conveyor 82 located adjacent the front end 30 of the body 24 and extending generally perpendicular to the endless conveyor 52. The cross conveyor 82 is arranged to selectively transport material received from the endless conveyor 52 to the first side wall 36 and the second side wall 38. The cross conveyor 82 is preferably mounted to the chassis 22. The cross conveyor 82 is illustrated in these figures in its preferred form as an auger.


[0049] The cross conveyor 82 is similar in construction and operation to the cross conveyor shown and described in U.S. patent application Ser. No. 09/256,053. It will be understood that the cross conveyor 82 can be provided in a variety of configurations, including, for example, but not limited to, a conventional conveyor belt or chain system with the top surface of the belt or chain defining the upper outer surface of the cross conveyor.


[0050] A front feed gate assembly 90 for selectively covering the opening 32 of the front end 30 of the body 24 is provided.


[0051] Referring to FIG. 1, a first side chute 92 is operably arranged with the conveyor assembly 50 to receive materials and direct materials to a side spreader 94 for selectively spreading materials. The first side chute 92 is mounted to the body 24 adjacent the first side wall 36. A second spreader mounting assembly 96 adjustably mounts the side spreader 94 to the chassis 22. Referring to FIGS. 2 and 3, a second side chute 102 is operably arranged with the conveyor assembly 50 to receive materials and direct materials to a surface, such as a roadway shoulder. The second side chute 102 includes a burming ramp 104 for depositing materials remotely from the vehicle 20. The second side chute 102 is mounted to the body 24 adjacent the second side wall 38.


[0052] Referring to FIGS. 1 and 2, the cross conveyor 82 is arranged to receive materials through the opening 32 of the front end 30 of the body 24 from the endless conveyor 52 and to transport selectively the materials to first and second side discharge ports 110, 112, which are mounted to the first and second side walls 36, 38, respectively. The ports 110, 112 can be arranged to deposit materials into the first and second side chutes 92, 102, respectively.


[0053] Referring to FIG. 1, the body 24 is secured to the chassis 22 about a pivot axis 114. More specifically, the body 24 is pivotably secured to the chassis 22 at the hinge 26 which allows for pivotal movement about the pivot axis 114. The hoist 40 includes a hydraulic cylinder 120 connected between the body 24 and the chassis 22 at a selected point 122 forward the pivot axis 114 of the body 24. The hoist 40 is operable to act upon the front end 30 of the body 24 to rotate the body 24 as indicated by an arrow 123 in FIG. 1 on the hinge 26 about the pivot axis 114 from a normal, horizontal position, as seen in FIG. 1, to a fully inclined position, as seen in FIG. 3.


[0054] Referring to FIGS. 1 and 2, to facilitate the storage and the selective dumping of materials in the body, the tailgate 60 is provided at the rear end 34 of the body 24 and extends transversely between the side walls 36, 38. The tailgate 60 is releasably and pivotably connected to the rear end 34 of the body 24. The tailgate 60 is selectively pivotable with respect to the body 24 about an upper pivot axis 140 disposed adjacent a top edge 142 of the tailgate 60 and about a lower pivot axis 144 disposed adjacent a lower edge 146 of the tailgate 60. Upper and lower pins 148, 150 extending from the tailgate 60 can be releasably secured to mounts 152, 154 on the body 24 to provide for selective pivotal movement about the upper and lower pivot axes 140, 144 of the tailgate 60.


[0055] When the tailgate 60 is secured at both axes 140, 144, the tailgate 60 generally prevents material in the body 24 from exiting the rear end 34 thereof. The tailgate 60 includes the opening 62 therein to permit material to be selectively transported therethrough by the endless conveyor 52 such that the tailgate 60 can remain secured during spreading. The tailgate 60 can be selectively released from the upper pivot axis 140 by releasing the upper pins 148 and pivoted about the lower pivot axis 144, thereby providing for ease in cleaning and rear loading of the body. The tailgate 60 can be released from the lower pivot axis 144 by releasing the lower pins 150 and pivoted about the upper pivot axis 140 when dumping is desired. If desired, the tailgate 60 may also be removed from the rear end 34 of the body 24.


[0056] Referring to FIGS. 1 and 2, a rear exposed portion 160 is provided, which includes an asphalt lip 162 that extends generally substantially horizontally rearward and below the tailgate 60 and a portion of the endless conveyor 52 that projects out beyond the rear end 34 of the body 24 and beyond the tailgate 60. Advantageously, the lip 162 extends at least six inches rearward of the body, preferably at least about 12 inches, and most preferably at least about 18 inches. It is further preferred that the asphalt lip 162 extend rearward to at least the same extent as the endless conveyor 52.


[0057] Referring to FIGS. 4-6, the rear feed gate assembly 70 is provided to selectively cover the opening 62 of the tailgate 60. The feed gate assembly 70 includes first and second support members 170, 171 mounted to the tailgate 60, a handle 172 rotatably mounted to the first and second support members 170, 171, a bailment 174 depending from the handle 172, and a cover plate 175 pivotally mounted to the bailment 174. The cover plate 175 is slidably mounted to the tailgate 60 to selectively cover the opening 62. The cover plate 175 is movable between a closed position and a range of open positions. The handle 172 positions the cover plate 175.


[0058] Referring to FIG. 5, the first and second support members 170, 171 are in spaced relation to each other and flank the opening 62 of the tailgate 60. The support members 170, 171 support the handle 172 such that the handle 172 can rotate. The handle 172 includes a shaft 176 and a gripping portion 177 depending therefrom. The handle 172 is cooperatively arranged with the bailment 174 to selectively move the bailment 174.


[0059] The bailment 174 includes a frame 178 and depending first and second pivotable links 182, 183. The frame 178 is generally U-shaped and is mounted to the shaft 176. The links 182, 183 are pivotally mounted to the frame 178 and to the cover plate 175.


[0060] The frame 178 includes first and second arms 184, 185 “in close proximity” to the first and second support members 170, 171, respectively. “In close proximity” means that the arm and the support member are within about two inches of each other, preferably within one inch of each other. The arm and the support member can be disposed with respect to each other such that the shaft does not deflect more than a predetermined value in operation. The close proximity of the arms 184, 185 to the support members 170, 171 places the load on the shaft 176 adjacent to the support members, 170, 171, thereby reducing the tendency of the shaft 176 to bend when opening or closing the cover plate 175.


[0061] Referring to FIG. 11, in the closed position, the plate 175 covers the opening 62 wherein a bottom edge 186 of the plate 175 rests on or is disposed just above the endless conveyor 52. The cover plate 175 can be moved to any of the range of open positions to control the size of the opening 62 in the tailgate 60. The cover plate 175 is adjustable to meter the flow of material through the opening 62 of the tailgate 60.


[0062] Referring to FIG. 5, in operation, the handle 172 can be moved by operating the gripping portion 177, which in turn rotates the frame 178. The frame 178 acts upon the links 182, 183 which pivot with respect to the frame 178 and raise and lower the cover plate 175 according to the movement of the handle 172.


[0063] An indexing member in the form of a circular indexing plate 189 is cooperatively arranged with the first support member 170 and the shaft 176 to provide a retaining mechanism for holding the handle 172, and thereby the cover plate 175, in a selected position. The indexing plate 187 is mounted to the shaft 176 of the handle 172. The indexing plate 187 includes a plurality of holes 188 which provide incremental adjustment of the handle 172. A pin 190 can extend through a bore 192 in the first support member 170 and a selected one of the holes 188 in the indexing plate 189 to retain the handle 172, and consequently the cover plate 175, in the selected position.


[0064] Referring to FIG. 6, the feed gate assembly 70 further includes a plurality of guide members 195 which guide the cover plate 175 during movement thereof relative to the guide members 195. The guide members 195 are mounted to the tailgate 60. The cover plate 175 includes first and second surfaces 196, 197. It is preferred that at least one guide member 195 is disposed on the first surface 196 of the cover plate 175 and at least one guide member 195 is disposed on the second surface 197 of the cover plate 175. The illustrative feed gate assembly 70 includes four guide members 195 in spaced relation to each other such that the cover plate 175 fits between the guide members 195. Two of the guide members 195 are disposed adjacent the first support member to guide the cover plate 175 from the first and second surfaces 196, 197 thereof. The other two guide members 195 are disposed adjacent the second support member 171 to guide the cover plate 175 from, respectively, first and second surfaces 196, 197 thereof.


[0065] Each guide member 195 is mounted to the tailgate 60. The illustrative guide members 195 each comprise a rod having a diameter of about ¼ inch and a length substantially equal to the height of the cover plate 175. The guide members 195 each include a curved contact surface which engages the cover plate 175. The configuration of the guide members reduces the amount of surface contact between the guide members and the cover plate 175, therefore reducing the amount of friction. By using rods, the chance for granular material to become lodged between the flat surface of the cover plate 175 and the guide members it rides on is greatly reduced.


[0066] Referring to FIG. 7, the tailgate cover 71 can be pivoted from a down position to an elevated position. The cover 71 includes a tab 202 for latching the cover in the elevated position to an ear 204 of the tailgate 60 by a pin and hole mechanism 206. In the down position, shown in FIG. 7, the cover 71 is generally held in place by gravity but could also be latched in place if desired.


[0067] When in the down position, the cover 71 prevents someone from stepping on the endless conveyor 52, which can be moving, and is allowed to float when material is conveyed out the rear, thereby creating little or no flow restriction.


[0068] The rotational capability of the cover 71 allows the operator to pivot the tailgate 60 about the lower pivot axis 144 without the cover 71 interfering. The cover 71 can be rotated to the elevated position and retained therein out of the way such that the tailgate 60 can be readily pivoted about the lower pivot axis 144 from the closed position to an open position without interference between the cover 71 and the endless conveyor 52. During movement of the tailgate 60, the cover 71 can pivot out of the way of the endless conveyor 52.


[0069] The front feed gate assembly 90 is provided at a panel 209 of the front end 30 of the body 24 to selectively cover the opening 32 therein to provide a degree of control over the expulsion of material from the front of the body 24 and onto the cross conveyor 82. The front feed gate assembly 90 is of similar function and construction as the rear feed gate assembly 70.


[0070] Referring to FIGS. 8 and 11, the front feed gate assembly 90 includes first and second support members 210, 211 mounted to the panel 209 of the front end 30 of the body 24, a handle 212 rotatably mounted to the first and second support members 210, 211, a bailment 214 depending from the handle 212, and a cover plate 215 pivotally mounted to the bailment 214. The cover plate 215 is slidably mounted with respect to the front end 30 to selectively cover the opening 32. The cover plate 215 is movable between a closed position and a range of open positions. The handle 212 positions the cover plate 215.


[0071] The bailment 214 is similar to the bailment of the rear feed gate assembly and includes a frame 220 and first and second pivotable links. The frame 220 of the bailment 214 has first and second arms 224, 225 “in close proximity” to the first and second support members, respectively. “In close proximity” means . . . .


[0072] Referring to FIGS. 8 and 9, the front feed gate assembly 90 includes guide members 230 similar in construction and function to those guide members described herein with respect to the rear feed gate assembly. In the illustrative embodiment, two guide members 230 are mounted to the front panel 209 adjacent the first and second support members 210, 211, respectively. Two other guide members 230 are mounted to the first and second support members 210, 211, respectively to establish a cooperating pair of guide members 230 adjacent each of the first and second support members 210, 211.


[0073] Referring to FIGS. 9 and 10, the handle 212 includes a shaft 216 having a coupling 218 for a slot and tang arrangement. The shaft 216 includes a first rod 240 having an end 242 with a slot 244 and a second rod 246 having a first end 248 with a tang 250 and a second end 252. The slot 244 and the tang 250 provide for the mounting of the first and second rods 240, 246 to each other. The “slot and tang” arrangement provides strength to the coupling 218 that readily avoids problems with tolerances and fit during manufacture as well as with field repairs and replacements. To allow the operator to use the handle 212, the second end 252 of the second rod 246 extends beyond one of the first and second side walls of the body. The front feed gate assembly 90 is similar in other respects to the rear feed gate assembly 70 shown and described herein.


[0074] Referring to FIG. 11, a conveyor cover assembly 260 can be provided that includes a cover 261 configured to completely cover the endless conveyor 52 along the length thereof. The cover 261 includes a front end 262 and a rear end 264. The front end 262 of the cover 261 is removably mounted to a front knee brace 266 of the front end 30 of the body 24 with a bracket 268, for example, that is bolted to the cover 261 and the knee brace 266. The rear end 260 of the cover extends rearwardly from the tailgate 60.


[0075] Mounting members 270, 272 are secured to the body 24 adjacent the rear end 264 of the cover 261. The illustrative mounting members 270, 272 are a pair of mounting tubes mounted to the body 24 at the rear end 34 of the body 24. The rear end 264 of the cover 261 includes a pair of tabs 274, 276 which is respectively removably mounted to the pair of mounting members 270, 272. The rear end 264 is secured with the tabs 274, 276 which are respectively inserted into the pair of mounting tubes 270, 272.


[0076] The cover 261 is configured to completely cover the endless conveyor 52 along the length thereof. With the front end 262 and the rear end 264 being removably mounted to the body 24, the cover 261 is easily removable. On the other hand, the cover 261 is mounted such that it is prevented from shifting around or detaching when the body 24 is in a dumping position.


[0077] The conveyor cover assembly 260 is particularly advantageous when the body 24 is used as a dumping body for extended periods of time. The operator can load the body 24 with materials, such as, large rocks or boulders, or broken sections of concrete containing steel reinforcement bar, for example. The cover assembly 260 protects the endless conveyor from damage that it might otherwise sustain from such materials.


[0078] Referring to FIG. 12, the rear diverter chute 72 is operably arranged with the conveyor assembly 50 to receive materials from the endless conveyor 52 of the conveyor assembly 50.

The panel 292 allows materials to move through the chute 72 to the spreader 74 when the panel 292 is disposed in the first position, i.e., the open position. The panel 292 helps direct material that is being conveyed from the conveyor assembly 50 from the body 24. The panel 292 prevents materials from moving through the diverter 72 to the spreader 74 when the panel 292 is disposed in the second position, i.e., the closed position. When the panel 292 is in the closed position, it is possible to dump material out of the body 24 and still protect the spreader 74. This protection feature is very beneficial when stock-piling material after finished spreading because the spreader 74 and the chute 72 need not be removed before dumping materials from the body 24.


[0080] Referring to FIG. 12, the rear spreader 74 is adjustably mounted to the vehicle 20 and cooperatively arranged with the endless conveyor 52 of the conveyor assembly 50 to receive and selectively spread materials.
