Description

BACKGROUND OF THE INVENTION

The present invention relates to dispensing aggregates, and more particularly, to a wheel or track loader self-loading center-dispensing bucket.

FIG. 1 shows a prior art device 10 for dispensing aggregates (including, but not limited to, a skid steer and other track loaders). Such a prior art device 10 includes a bucket 12 that provides no precision when dispensing aggregates in general and, in particular, in tight spaces. Due to the lack of precision, there are significant resultant increases in the amount of time and labor required for construction projects, such as backfilling a trench.

As can be seen, there is a need for a device that provides time and labor savings in dispensing aggregates.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the present invention.

Broadly, an embodiment of the present invention provides a wheel or track loader 11 provisioned with a bucket 14 and a material discharge component 16 and a method for loading and dispensing materials 30, such as aggregates, sand, soil, and the like. The present invention provides a time and labor-saving material dispenser capable of being attached to a loader 11. In some embodiments, the dispenser comprises a loader 11, an articulating bucket 14, and a hydraulically activated material discharge component 16. The bucket 14 may be loaded by opening the material discharge component 16 and submersing the bucket 14 into material 30 to be dispensed so that the material 30 is collected in a receptacle portion of the bucket 14. In other embodiments, the material dispenser comprises an integral bucket 14 and material discharge component 16 having a central dispensing opening 26, and the bucket 14 may be loaded by other construction equipment.

The system of the present invention provides an advancement over prior art devices, an example of such prior art devices is shown at FIG. 1. As seen at FIG. 1, the use of such prior art devices 10 that include conventionally designed buckets 12 for dispensing aggregates is cumbersome, time-consuming, wasteful, and causes negative impact to a construction site, requiring clean up after use. The present invention is particularly adapted for use in dispensing aggregates 30 into tight spaces, such as covering drain tile, pipes, and backfill for trenches and other linear excavations.

As seen, for example, at FIGS. 2-10, the present invention may provide a material dispensing apparatus 40. The material dispensing apparatus 40 may comprise a self-loading wheel or track loader 11 and a bucket 14 pivotally coupled to articulating load arms 13 of the loader 11. A material discharge component 16 is pivotally coupled to an aft end (i.e., a rear end) of the bucket 14 and is operable between an open position and a closed position by an actuator 28 (which may be comprised of a pair of actuators 28, as shown in FIG. 4).

The material discharge component 16 has a left and a right-side arm 24. A pivot 24A and an actuator coupling 24B (spaced from the pivot 24A) are provided at an aft end of the left and the right-side arms 24. Each pivot 24A rotatably couples engages a first bucket bracket 14A that is disposed on an upper surface of the bucket 14. The actuator 28 is rotatably coupled to the material discharge component 16 at the actuator coupling 24B via a pin 24C and is pivotally coupled to a lower aft end of the bucket 14 to a second bucket bracket 14b (such that the actuator 28 runs along the aft end of the bucket 14). The lower edge of the left and right-side arms 24 engage with a forwardly projecting edge of lateral sidewalls of the bucket 14.

The material discharge component 16 has a front wall section 22 that converges forwardly in a V shape from a front end of the left and the right-side arms 24. An opening 26 is defined at the convergence of the front wall section 22. A top plate 18 interconnects with a top edge of each of the left and right-side arms 24 and the front wall section 22. Preferably, the top plate 18 is elevated from each of the left and right-side arms 24 and the front wall section 22 to provide containment of a greater volume of material 30 in the opening 27 when the bucket 14 and the material discharge component 16 are articulated to dispense materials 30.

A bottom plate 20 extends rearwardly from a bottom edge of the front wall section 22. An aft edge of the bottom plate 20 is configured such that it aligns with a lip extending laterally across a bottom edge of the bucket 14. The aft edge facilitates retention of the materials 30 within the bucket 14 when the material discharge component 16 is moved to the closed position.

In some embodiments, the material discharge component 16 may be actuated hydraulically via actuator 28 (which, as shown in FIG. 4 and mentioned above, may be a pair of actuators 28 positioned on opposite lateral ends of the bucket 14 that couple with respective pins 24C) to open and close the bucket 14 for loading of material 30. As shown at FIG. 11, the material discharge component 16 may be hydraulically lifted to enable the user to load the bucket interior 14 with a material 30 to be dispensed. Then, as seen in FIG. 12, after the bucket is loaded, the material discharge component 16 may be hydraulically lowered to pivot into place for use in dispensing the material 30 from the front opening 26 thereof.

The present invention and its components may be made of any suitable material by any suitable fabrication process. The present invention and its components may have any suitable dimensions, depending upon the size of the excavations to be filled and the size and capacity of the loader vehicle 11.

FIG. 11 shows an exemplary embodiment of the present invention as in FIG. 2, in use showing the bucket 14 being loaded with a material 30, a non-limiting example of which may be aggregate rock 30. It is seen that the pivotally mounted the material discharge component 16 is pivoted upward to enable the loading of the self-dispensing bucket 14 with the material 30 to be dispensed. In use, the dispenser bucket is loaded by any suitable construction equipment, such as, for example without limitation, pouring an aggregate slurry from a concrete truck or mixer.

Referring now to FIG. 12, the material discharge component 16 may be pivoted downward into place to close with a front edge and sides of the bucket 14 contain the loaded material 30 within the bucket 14.

Referring to FIG. 13, after the material discharge component 16 and bucket 14 are loaded with material 30 to be dispensed, the user may transport the materials in the bucket 14 to locations for dispensing of the materials 30 where the materials 30 are needed. The bucket 14 is pivoted rearwardly so that the materials 30 are contained within the bucket 14 and the material discharge component 16 and prevent materials from spilling from the opening 26.

As shown in FIGS. 14 and 15, when the operator has reached the desired excavation to fill, the opening 26 is positioned aligned with the trench. The bucket 14, with the material discharge component 16 retained in the closed position, is tilted forwardly so that the materials 30 are dispensed through the opening 26 into the excavation. The operator may adjust the dispensing rate of the apparatus by varying the tilt angle of the bucket 14. The elevated top plate 18 of the material discharge component 16 facilitates guidance of the material 30 through the opening 26.

The center-dispensing bucket of the present invention may be used to dispense any flowable material, such as, for example without limitation, concrete, sand, gravel, or the like. In use, the present invention may save time and money. Whether loaded by other construction equipment or self-loading, the center-dispensing device is completely unprecedented and was developed in response to a need for such a device.

For clarity, only those aspects of the system germane to the present invention are described, and product details well known in the art are omitted. In addition, many embodiments of the present invention have application to a wide range of industries. To the extent the present application discloses a system, the method implemented by that system is within the scope of the present invention. Further, to the extent the present application discloses a method, a system of apparatuses configured to implement the method are within the scope of the present invention.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the present invention.
