The hopper has a volume of about four cubic yards.

Description

BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to a refuse box or hopper for use with a flat-bed truck, a pick-up truck or trailer. More particularly, this invention relates to a refuse box or hopper which is capable of dumping the refuse therein into a larger dumpster or a packer truck. Even more particularly this invention relates to a refuse hauler which is smaller than other refuse haulers to that the refuse hauler of this invention is highly mobile and which is able to collect and compact refuse from locations wherein a large trash or refuse hauler could not reach.

Description of the Related Art

Many types of garbage or refuse trucks have been previously provided. In most cases, the refuse trucks of the prior art are very large and difficult to maneuver. Further, in many instances, the refuse to be picked up by the large trucks is minimal and hardly worth the time effort to collect the refuse from smaller sites.

SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.

A refuse box or hopper is disclosed which may be used with either a flat-bed truck, a pick-up truck or a trailer. The refuse box or hopper of this invention is capable of dumping the refuse therein into a larger dumpster or packer truck. The invention includes a horizontally disposed support frame having a front end, a rear end, a first side and a second side. The support frame is secured to the box of a pick-up truck or to the bed of a trailer. An upstanding first hopper support, having a lower end, an upper end, a front side and rear side, with its lower end secured to the support frame at the rear end thereof. A first bearing is mounted on the upper end of the first hopper support. An upstanding second hopper support, having a lower end, an upper end, a front side and a rear side, has its lower end secured to the support frame at the rear end thereof. The first and second hopper supports are spaced apart. A second bearing is mounted on the upper end of the second hopper support.

A refuse hopper is pivotally mounted on the support frame and has a volume of approximately 4.0 cubic yards. The refuse hopper includes a front wall, a first side wall, a second side wall, a rear wall and a bottom wall. The rear wall of the refuse hopper is in inclined and has a lower end, an upper end, an inner side, an outer side, a first side and a second side. The rear wall extends upwardly and rearwardly from the lower end thereof to the upper end thereof. The bottom wall of the hopper extends between the lower ends of the first side wall, the second side wall, the front wall and the rear wall.

The rear wall of the refuse hopper is pivotally secured to the first and second bearings on the upper ends of the first and second upper supports respectively. A first hydraulic cylinder, having a base end and a rod end, has its base end pivotally secured to the support frame and has its rod end pivotally secured to the rear wall of the refuse hopper. A second hydraulic cylinder, having a base end and a rod end, has its base end pivotally secured to the support frame and has its rod end pivotally secured to the rear wall. The extension of the first and second hydraulic cylinders cause the hopper to pivotally move from a loading position towards a dumping position.

A compactor plate is pivotally secured, about a transverse horizontally disposed axis, to the rear wall of the hopper. A third hydraulic cylinder, having a base end and a rod end, is movable between retracted and extended positions. The base end of the third hydraulic cylinder is operatively secured to the hopper. A linkage pivotally secures the rod end of the third hydraulic cylinder to the upper end of the compactor plate. The compactor plate is positioned between the first and second side walls when the third hydraulic cylinder is in the extended position. The compactor plate is in a horizontally disposed position when the third hydraulic cylinder is partially extended. The compactor plate is an upright position above the hopper when the third hydraulic cylinder is in the retracted position. The compactor plate functions as a wind screen when in a horizontally disposed position.

It is therefore a principal object of the invention to provide an improved refuse hopper.

A further object of the invention is to provide a refuse hopper having a capacity of approximately four cubic yards.

A further object of the invention is to provide a refuse hopper which may be mounted on a pick-up truck or a trailer.

A further object of the invention is to provide a refuse hopper having a smaller size than most refuse haulers.

A further object of the invention is to provide a refuse hopper which is economical of manufacture, durable in use and refined in appearance.

FIG. 21 illustrates the hydraulic system 244 of this invention. System 244 includes a hydraulic fluid reservoir 246 which is fluidly connected to a strainer 248 by line 250. Line 252 fluidly connects strainer 248 to an electrically driven pump 254 which is driven by a 12-volt motor 256. The numeral 260 refers to a solenoid operated directional control assembly. Fluid line 262 extends from assembly 260 to one end of hydraulic cylinder 132. Fluid line 264 extends from line 262 to one end of hydraulic cylinder 126. Line 270 extends from assembly 260 to reservoir 246.

Assuming that the cylinders 126 and 132 are in the retracted position of FIG. 21, the cylinders 126 and 132 will be filled with hydraulic fluid outwardly of the pistons thereof. When the cylinders are in the retracted position, the hopper 14 will be in the lower loading and transport position when it is desired to pivot the hopper 14 from the loading and transport position of FIG. 1 to the dumping position of FIG. 6, the assembly 260 will be operated to supply hydraulic fluid to the inner end of cylinder 126 by way of lines 262 and 264 and to supply hydraulic fluid to the inner end of cylinder 132 by way of line 262 to extend the cylinders 126 and 132. During the extension of cylinders 126 and 132, hydraulic fluid in the cylinders outwardly of the pistons thereof will be exhausted to the assembly 260 by way of lines 268 and 266 and then supplied to reservoir 246 by way of line 270. When it is desired to pivot the hopper 14 from its dumping position to its loading and transport position, assembly 260 will be operated to supply hydraulic fluid to the outer ends of cylinders 126 and 132 by way of the lines 266 and 268. At that time, the hydraulic fluid in the cylinders 126 and 132 inwardly of the pistons thereof will be supplied to assembly 260 by way of the lines 264 and 262 and then returned to reservoir 246 by line 270.

The numeral 272 refers to a solenoid operated directional control valve assembly. Assembly 272 is connected to the inner end of hydraulic cylinder 228 by fluid line 274. Assembly 272 is fluidly connected to the outer end of hydraulic cylinder 228 by line 276. Assembly 272 is fluidly connected to line 258 by line 278. A pressure relief valve 280 is imposed in line 278. Hydraulic fluid is supplied to hydraulic cylinder 228 by line 274 to cause hydraulic cylinder 228 to extend. When hydraulic fluid is supplied to hydraulic fluid by way of line 276, hydraulic cylinder 228 will retract.

The components within the dashed lines are part of the 12-volt motor pump 256. All valves are controlled by momentary switches.

Thus it can be seen that the invention accomplishes at least all of its stated objectives.

Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
