Spread control mechanism

Abstract

A broadcast spreader and methods of using the same. One method includes dispersing particulate material using a broadcast spreader having a hopper and an impeller by placing the spreader in a first configuration where a first set of through openings proximate a bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a first spread pattern, and shifting the spreader into a second configuration where a second set of through openings proximate the bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a second spread pattern. The first set of through openings includes a different number of through openings than the second set of through openings, and the first spread pattern is different than the second spread pattern.

Description

ORIGIN

The innovation disclosed herein relates to a particulate dispersing apparatus and, more specifically, to a granular spreader having a spread control mechanism.

BACKGROUND

A known particulate spreader incorporates a deflector that when activated impedes particulate material from exiting out one side of the spreader. Thus, any material dispersed in the spread pattern is impeded from spreading onto non-lawn areas, such as landscape beds, driveways, walkways, etc. In other words, the deflector simply deflects the dispensed material back toward the lawn area. A disadvantage of material dispersing systems that rely on such a deflector is that the amount of material dispersed (material flow rate) into the spread pattern remains the same whether or not a deflector is activated. Thus, if the deflector is activated the amount of material directed onto the lawn is more than the recommended amount since the deflected material also exits the side of the spreader opposite that of the deflector. This leads to over treatment of the lawn and to wasted product.

SUMMARY

The following presents a simplified summary in order to provide a basic understanding of some aspects of the innovation. This summary is not an extensive overview of the innovation. It is not intended to identify key/critical elements or to delineate the scope of the innovation. Its sole purpose is to present some concepts of the innovation in a simplified form as a prelude to the more detailed description that is presented later.

Some embodiments are directed to a method of dispersing particulate material using a broadcast spreader having a hopper and an impeller disposed below the hopper. The method includes placing the broadcast spreader in a first configuration where a first set of one or more through openings proximate a bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a first spread pattern during use of the broadcast spreader. The method also includes shifting the broadcast spreader into a second configuration where a second set of one or more through openings proximate the bottom portion of the hopper permit the particulate material to pass therethrough and fall onto the impeller to thereby be distributed in a second spread pattern during use of the broadcast spreader. The first set of one or more through openings includes a different number of through openings than the second set of one or more through openings, and the first spread pattern is different than the second spread pattern.

Other embodiments are directed to a method of dispersing particulate material using a broadcast spreader including a hopper and an impeller that disperses particulate material falling thereon from the hopper. The method includes operating the broadcast spreader in a first configuration by providing a first set of one or more through openings proximate a bottom portion of the hopper resulting in a first spread pattern. The method also includes operating the broadcast spreader in a second configuration by providing a second set of one or more through openings proximate a bottom portion of the hopper resulting in a second spread pattern. The number of through openings included in the first set of one or more through openings is different than a number of through openings included in the second set of one or more through openings, and the first spread pattern is different than the second spread pattern.

Still other embodiments are directed to a broadcast spreader that operates in multiple configurations thereby providing multiple spread patterns. The broadcast spreader includes an impeller and a hopper disposed above the impeller that drops particulate material onto the impeller. When the broadcast spreader is in a first configuration, the broadcast spreader includes a first set of one or more through openings proximate a bottom portion of the hopper such that, during use of the broadcast spreader in the first configuration, the particulate material is configured to pass through the first set of one or more through openings and fall onto the impeller to thereby be distributed in a first spread pattern. And when the broadcast spreader is in a second configuration, the broadcast spreader includes a second set of one or more through openings proximate a bottom portion of the hopper such that, during use of the broadcast spreader in the second configuration, the particulate material is configured to pass through the second set of one or more through openings and fall onto the impeller to thereby be distributed in a second spread pattern. The first set of one or more through openings includes a different number of openings than the second set of one or more through openings, and the first spread pattern is different than the second spread pattern.

DETAILED DESCRIPTION

The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the innovation can be practiced without these specific details.

While specific characteristics are described herein (e.g., thickness), it is to be understood that the features, functions and benefits of the innovation can employ characteristics that vary from those described herein. These alternatives are to be included within the scope of the innovation and claims appended hereto.

While, for purposes of simplicity of explanation, the one or more methodologies shown herein, e.g., in the form of a flow chart, are shown and described as a series of acts, it is to be understood and appreciated that the subject innovation is not limited by the order of acts, as some acts may, in accordance with the innovation, occur in a different order and/or concurrently with other acts from that shown and described herein. For example, those skilled in the art will understand and appreciate that a methodology could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with the innovation.

Disclosed herein is an innovative spread control assembly for use on a particulate dispersing apparatus that when activated impedes particulate material from being dispersed out one side of the particulate apparatus in accordance with an aspect of the innovation. When activated, the assembly overcomes the aforementioned disadvantage by simultaneously regulating a material flow rate of the particulate material, which impedes over treatment of the lawn and wasted material. Thus, the spread control assembly facilitates the reduction of particulate material that is dispersed onto non-lawn areas (e.g., landscape beds, driveways, etc.) while simultaneously regulating the material flow rate.

With reference now to the figures, FIGS. 1A and 1B illustrate example embodiments of a particulate material dispersing apparatus 100A, 100B that incorporates the innovative spread control assembly 200 (shown in FIG. 1A) in accordance with aspects of the innovation. It is to be understood that the particulate material dispersing apparatus 100A, 100B may be any type of particulate dispersing apparatus capable of dispersing particulate and/or granular material (hereinafter “material”), such as but not limited to lawn seed/fertilizer, salt, etc. In addition, the particulate material dispersing apparatus 100A, 100B may be a walk behind type spreader, a hand-held type spreader, a tow-type spreader, etc. The example particulate material dispersing apparatus 100A, 100B illustrated in FIGS. 1A and 1B are walk behind type spreaders and will be used to describe the innovation disclosed herein. Thus, the example particulate material dispersing apparatus 100A, 100B illustrated in FIGS. 1A and 1B are for illustration purposes only and are not intended to limit the scope of the innovation.

Still referring to FIGS. 1A and 1B, the example particulate material dispersing apparatus 100A, 100B, includes a frame 102A, 100B, a vessel or hopper 104A, 104B, mounted to the frame 102A, 102B, a push handle 106A, 106B mounted to the frame 102A, 102B, an open-close/adjustment (shut-off) assembly 108A, 108B, a pair of wheels 110A, 110B, a dispersing mechanism 112A, 112B disposed below the innovative spread control assembly and configured to disperse product from inside the hopper 104A 104B, and a gear box 114A, 114B operatively connecting the wheels 110A, 110B, and the dispersing mechanism 112A, 112B via an axle 116A, 116B, and a gear/impeller shaft 118A (best shown in FIG. 1A).

In the example embodiment illustrated in the figures, the hopper 104A, 104B has a rectangular type shape, as viewed from the top, but it is understood that the shape of the hopper 104A, 104B can be any shape, such as but not limited to square, circular, etc. One or more openings 105 (see FIGS. 28 and 29) are defined in a bottom of the hopper 104A, 104B that facilitates the dispersing of the particulate material in association with the innovative spread control assembly 200.

FIGS. 2-7 illustrate the innovative spread control assembly 200 in a nonactivated (open) state in accordance with an aspect of the innovation. In the nonactivated state, the spread control assembly 200 allows the dispersion of material in all directions, as will be explained further below. FIGS. 8-13 illustrate the spread control assembly 200 in an activated (closed) state in accordance with an aspect of the innovation. In the activated state, the spread control assembly 200 impedes the dispersion of material in one side direction and allows the dispersion of material in an opposite side direction while simultaneously reducing the material flow rate.

Thus, the spread control assembly 200 is configured to alter a material spread pattern of the particulate material dispersing apparatus 100A, 100B. More specifically, the spread control assembly 200, when activated, impedes material from being dispersed through one or more exit openings defined in a shut-off adjustment plate explained further below. Therefore, a reduced amount of material is dispersed through only those remaining exit openings not covered by a spread control mechanism thereby eliminating product overuse and waste.

In addition, activation of the spread control assembly 200 causes the material to be dispersed outward from one side of the particulate material dispersing apparatus 100A, 100B while impeding material from being dispersed out an opposite side of the particulate material dispersing apparatus 100A, 100B. Thus, any material dispersed in the altered-spread pattern is impeded from spreading onto non-lawn areas, such as landscape beds, driveways, walkways, etc. It is to be understood that the spread control assembly 200 can be configured to impede material dispersion from either side of the dispersing apparatus 100A, 100B. Thus in one example embodiment, the material may be dispersed from a first side (e.g., left or right) and impeded from being dispersed from a second side (e.g., right of left). Therefore, the example embodiment described herein and illustrated in the figures is for illustrative purposes only and is not intended to limit the scope of the innovation.

As illustrated in FIGS. 2-13, the innovative spread control assembly 200 includes a spread control mechanism 300, a shut-off adjustment plate 400, and a pivot mechanism 500 that pivotally connects the spread control mechanism 300 and the shutoff adjustment plate 400.

Referring to FIGS. 14-19, in the example embodiment illustrated in the figures, the spread control mechanism 300 includes a handle 302, multiple paddles including a first paddle 304, a second paddle 306, and a curved pivot engagement portion 308. The curved pivot engagement portion 308 facilitates the pivoting motion of the spread control mechanism 300 about the pivot mechanism 500. The spread control mechanism 300 attaches to the shut-off adjustment plate 400 via a fastener 310 that extends through a slot 312 defined in the spread control mechanism 300. The handle 302 connects to an end 314 of the first paddle 304 that is distal from the pivot mechanism 500. The handle 302 facilitates movement of the spread control mechanism 300 between and an activated (closed) and deactivated (open) state. The spread control mechanism 300 has a V-shaped configuration whereby the first and second paddles 304, 306 are spaced to facilitate application of material.

Referring to FIGS. 20-25, the shut-off adjustment plate 400 includes the multiple exit openings 402 defined therein and multiple elongated curved openings 404 that serve as hopper attachments openings whereby the shut-off adjustment plate 400 attaches to an outside bottom of the hopper 104A, 104B. The shut-off adjustment plate 400 is movable between a fully closed position and a fully open position. In the fully closed position, the shut-off adjustment plate 400 covers one or more openings at the bottom of the hopper, thereby preventing any particulate from exiting the particulate dispersing apparatus 100A, 100B. In the fully open position, the shut-off adjustment plate 400 does not cover any openings at the bottom of the hopper, thereby allowing maximum flow of particulate to be dispersed by the particulate dispersing apparatus 100A, 100B. The shut-off adjustment plate 400 further includes a vertically projecting stop mechanism 406, a control rod attachment opening 408, multiple hold down openings 410 (FIG. 21) that receive fasteners 412 that serve to hold down the spread control mechanism 300, and a spread control mechanism guide opening 414 (FIG. 21) that receives the fastener 310 mentioned above.

There are three exit openings 402 defined in the shut-off adjustment plate 400 in the example embodiment illustrated in the figures. It is to be understood, however, that there can be any number of exit openings 402 defined in the exit plate 400. In one example embodiment, the number of exit openings 402 is at least one greater than a number of paddles 304, 306. Thus, when the spread control mechanism 300 is activated all but one exit opening 402 will be covered thereby impeding any material from exiting the covered exit openings 402. Therefore, a reduced amount of material will exit the remaining exit openings 402, which directs the material to exit one side of the particulate material dispersing apparatus 100A, 100B.

When the spread control mechanism 300 is in a non-activated position, as shown in FIGS. 2-7, the spread control mechanism 300 is positioned such that all of the exit openings 402 are uncovered. The spread control mechanism 300 is slidably attached through the curved slot 312 via a washer head screw or other suitable device. Thus, the handle 302 may be grasped and moved, thereby urging the spread control mechanism 300 to be moved or slid along the path defined by slot 312 so as to move the spread control mechanism 300 between the activated (closed) and deactivated (open) state. The vertically projecting stop mechanism 406 impedes the spread control mechanism 300 from pivoting past the associated exit openings 402 intended for selective closure.

The pivot mechanism 500 is circular and is integrated into the shut-off adjustment plate 400. The curved pivot engagement portion 308 of the spread control mechanism 300 engages the pivot mechanism 500 to facilitate pivoting of the spread control mechanism 300 with respect to the shut-off adjustment plate 400. Thus, in order to pivot the spread control mechanism 300, the user pivots or rotates the user pivots or rotates the spread control mechanism 300 about the pivot mechanism 500 to the desired position.

Although, the spread control assembly illustrated in the figures is configured to disperse material out a particular side of the particulate dispersing apparatus, it is to be understood that in an alternate embodiment, the spread control assembly can be configured to disperse particulate material out an opposite side of the particulate dispersing apparatus.

The shut-off adjustment plate 400 is connected to the open-close/adjustment assembly 108A, 108B. When the open-close/adjustment assembly 108A, 108B is in a first position, the shut-off adjustment plate 400 is in a fully closed position (see FIG. 28). In this position, the shut-off adjustment plate 400 covers openings 105 in the bottom of the hopper 104A, 104B and hence prevents any particulate from exiting the dispersing apparatus 100A, 100B. Conversely, when the open-close/adjustment assembly 108A, 108B is in a second position, the shut-off adjustment plate 400 is in a fully open position (see FIG. 29). In this position, the shut-off adjustment plate 400 is not covering the openings 105 and hence allows a maximum flow of particulate to be dispersed by the dispersing apparatus 100 (subject to material spread pattern alteration by the spread control mechanism 300 as discussed above).

FIG. 26 illustrates an example alternate embodiment of a spread control assembly 2600 similar to the spread control assembly 200 disclosed above in accordance with an aspect of the innovation. The spread control assembly 2600 includes a spread control mechanism 2610, a shut-off adjustment plate 2620, and a pivot mechanism 2630 that pivotally connects the spread control mechanism 2610 and the shut-off adjustment plate 2620. One difference between the spread control assembly 2600 illustrated in FIG. 26 and the spread control assembly 200 illustrated above is that the spread control assembly 2600 does not include the slots 404 defined in the shut-off adjustment plate 400. All other features and functions between the two spread control assemblies 200, 2600 are similar and thus, will not be repeated.

Referring to FIG. 27, a process of dispersing particulate material will now be described in relation to the spread control assembly 200 illustrated in FIGS. 2-25 in accordance with one aspect of the innovation. At 2702, a spread control assembly 200 in a non-activated state for a particulate material dispersing apparatus is provided. At 2704, a spread control mechanism 300 is moved via the handle 302 in a direction such that the spread control assembly 200 is in an activated state. At 2706, the paddles 304, 306 cover exit openings 402 defined in the shut-off adjustment plate 400 thereby impeding particulate material from be dispersed through the covered exit openings 402. At 2708, particulate material is dispersed in a direction that corresponds to the side opposite the covered exit openings 402. Simultaneously, at 2710, particulate material is impeded from being dispersed in a direction that corresponds to the side of the covered exit openings 402. Simultaneously at 2712, an amount of dispersed particulate material is reduced thereby minimizing particulate material waste. At 2714, the spread control mechanism 300 is moved in a direction such that the spread control assembly 200 is in a de-activated position. At 2716, the paddles 304, 306 are moved such that the exit openings 402 are uncovered. At 2718, particulate material is dispersed in all directions. The process is repeated as the need arises to impede the dispersing of particulate material in a particular direction so as to impede the dispensing of particulate material on unwanted surfaces, such as driveways, walkways, landscape beds, etc.

What has been described above includes examples of the innovation. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the subject innovation, but one of ordinary skill in the art may recognize that many further combinations and permutations of the innovation are possible. Accordingly, the innovation is intended to embrace all such alterations, modifications and variations that fall within the spirit and scope of the appended claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
