DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

Turning now to FIGS. 1-4, several aspects of this disclosure relate to a translocatable hopper 10 that is mounted for example at the forward part of a front-end loader vehicle 14. The hopper 10 receives, re-positions and delivers a slurry 12 to a jobsite and preferably is detachably attached to the vehicle 14. In several embodiments, the hopper 10 is translocatable from a resting position (see, e.g., FIG. 3) to a delivery position through one or more intermediate positions.

One embodiment of the hopper 10 includes a floor 16 (FIG. 1) and walls 18, 20, 22, 24 that extending upwardly from the floor 16. The walls include a front wall 18 from which the slurry is delivered to a jobsite, a pair of side walls 20, 22 and a back wall 24 that faces the vehicle 14.

Preferably, the front wall 18 (FIGS. 1-2) has an outlet gate 26 and a chute 28 extending therefrom. The chute 28 is configured to direct slurry into the jobsite. A rising and falling sluice gate 30 is associated with the chute 28. In several embodiments, the gate 30 is oriented in a plane that is inclined to a vertical plane when the hopper 10 is in the resting position (see, FIG. 3). The slurry 12 moves outwardly and downwardly from the chute 28 when the sluice gate 30 is at least partially opened as the hopper 10 is placed at or near the delivery position above the jobsite.

In several embodiments, the translocatable hopper 10 has a footprint that is substantially hexagonal (see, FIG. 2). The walls have an upper edge 32 and a lower edge 34. When the hopper 10 is in the resting position, slurry tends to pool, thereby creating a center of gravity of an assembly of the hopper and the slurry.

As depicted in FIGS. 1 and 2, the front wall 18 has two inclined sections 36,38 that meet on either side of the chute 28, so that slurry 12 is funneled and flows forwardly towards the chute 28 and sluice gate 30 as the hopper 10 is pitched forwardly.

The hopper has an imaginary pitch axis about a lateral horizontal reference line (P, FIG. 1), a roll axis about a longitudinal reference line (R) and a yaw axis about a vertical reference line (Y). As slurry is dispensed, the center of gravity of an assembly of the hopper and the slurry tend to move rearwardly toward the vehicle 14. This movement tends to promote stability of the vehicle, hopper and slurry. Such stabilizing characteristics in turn have safety benefits, particularly when the vehicle lies on an inclined terrain and the hopper is oriented toward distal end regions of its path. In such regions, the turning moment is greater than when the hopper lies proximate its resting position. Safety and stability require attention in such configurations.

To support the hopper 10, the vehicle 14 has a leading end 40 (FIG. 1) from which one or more forks 42 extend. The lower edge of the back wall 24 is pivotably attached to the vehicle leading end 40. After attachment of the hopper 10, the forks 42 and thus the hopper 10 can be raised, lowered, extended forwardly or retracted rearwardly between a hopper resting position, a delivery position or moved through intermediary positions. Thus, the leading end 40 of the vehicle 14 and the translocatable hopper 10 can be raised from the resting position, lowered from the delivery position and moved between intermediate positions so that the hopper may be repositioned.

In several embodiments, the translocatable hopper 10 includes a hydraulic subassembly 44 (FIGS. 2,3). The subassembly has a passive end region 46 attached below the upper edge of the sluice gate 30 and an active end region attached at a lower end region 50 of the sluice gate 30. The hydraulic subassembly 44 is configured to raise and lower the sluice gate 30.

In several embodiments, there is provided a vibrator 52 (FIG. 1) for vibrating the hopper and the slurry about the longitudinal axis (R) so that slurry adhering to the walls descends and drainage of the slurry from the hopper is facilitated. Such a vibrator may for example include an electric motor coupled with a subassembly that induces oscillatory or rocking movement.

As the hopper 10 reaches a delivery point, there is also provided a pitching device for pitching the hopper 10 about the horizontal reference line (P), (FIG. 1) or tilting it so that when the hopper 10 is pitched forwardly over the jobsite and the sluice gate 30 is at least partially opened, slurry flow under gravitational influence is facilitated.

With primary reference to FIGS. 1-3, the hydraulic subassembly 44 includes a rod, a cylinder, a piston and one or more hydraulic lines 56 connecting a source of hydraulic power 58 and the cylinder 60. The sluice gate 30 can be raised and lowered and the hopper 10 can be vibrated about the horizontal axis (P) and/or the vertical axis (R) to facilitate delivery of the slurry 12. Thus, means are provided for vibrating the hopper to facilitate evacuation of the slurry from the chute.

Preferably, as shown in FIG. 1, the chute 28 has an upper edge 62 extending from the upper edge of the front wall 18, a triangular side wall 64 with an apex 66 situated at the upper edge of the front wall 18, and a lower side 68 extending from the lower edge of the front wall 18. A hypotenuse side 70 extends forwardly from the upper edge. The sluice gate 30 is slidingly raised and lowered and is supported by the hypotenuse 70.

As shown in FIGS. 3-4, attachment plates 72 extend rearwardly from the lower edge of the back wall 24 for securing the hopper 10 to the vehicle 14.

It will be appreciated that the vehicle 14 may be selected from the group consisting of a multi terrain loader, a dump buggy, a track dumper-buggy, a concrete-power buggy, a radial skid loader, a vertical skid loader, a track loader and an articulated loader.

It will also be appreciated that the slurry 12 may be selected from the group consisting of concrete, cement, mortar, pebbles, rocks, gravel, compost, mulch, soil, dirt, construction waste, and mixtures thereof.

In several embodiments, the sluice gate 30 is adapted to be positionable at or between a raised position, a lowered position and one or more intermediate positions.

In use, the hopper 10 and the slurry 12 have a center of gravity that moves rearwardly as slurry is delivered. As the slurry 12 moves through the chute 28, the center of gravity moves rearwardly, thereby enhancing stability of the hopper and the slurry so that any forwardly-directed tipping tendencies of the hopper and the vehicle are mitigated.
