Abstract

The accessory apparatus is used in conjunction with the vehicle for backfilling a trench. The accessory has a frame with first and second ends. Wheels are rotatably mounted to the first and second ends of the frame, with the wheels being structured and arranged to bear on ground beneath the frame. An auger is rotatably mounted to the ends of the frame. The auger has a shaft with flighting extending outward therefrom. The shaft is horizontal when the apparatus is in use. The auger has a height that is relative to the ground. A motor is coupled to one end of the frame, the motor causing the auger to rotate. A mounting bracket is pivotally coupled to the frame. The mounting bracket is structured and arranged to mount to the vehicle. As the frame pivots with respect to the mounting bracket, the height of the auger is raised or lowered relative to the ground. The mounting bracket can be pivotally coupled by a single set of pins, wherein a screw jack is used to pivot the frame relative to the mounting bracket. Alternatively, a four bar linkage can be used to couple the frame to the mounting bracket. If the vehicle can change the orientation of the mounting bracket relative to vertical, then the mounting bracket can be fixedly coupled to the frame.

Claims

1. An accessory apparatus for use in conjunction with a vehicle in backfilling a trench, comprising:

a) a frame having first and second ends;

b) wheels rotatably mounted to the first and second ends of the frame, the wheels being structured and arranged to bear on ground beneath the frame;

c) an auger rotatably mounted to the first and second ends of the frame, the auger having a shaft with flighting extending radially outward therefrom, the shaft being oriented horizontally when the apparatus is in use and the auger having a height relative to the ground;

d) a motor coupled to the frame and to the auger, the motor causing the auger to rotate;

e) a mounting bracket pivotally coupled to the frame, the mounting bracket being structured and arranged to removably mount to the vehicle, wherein the frame can move so as to adjust the height of the auger relative to the ground.

2. The accessory apparatus of claim 1 further comprising a screw jack extending between the frame and the mounting bracket, the screw jack adjusting the height of the auger relative to the ground.

3. The accessory apparatus of claim 1 wherein the motor is a hydraulic motor that is structured and arranged to be hydraulically coupled to the vehicle.

4. The accessory apparatus of claim 3 wherein the motor is located on one of the first or second ends.

5. The accessory apparatus of claim 1 wherein the auger has a first portion of flighting, a second portion of flighting, and a center portion located between the first and second portions, the flighting on the first portion being in a first direction and the flighting on the second portion being in a direction that is opposite to the first direction.

6. The accessory apparatus of claim 1 wherein the mounting bracket is pivotally coupled to the frame by at least one pin located adjacent to a bottom of the mounting bracket.

7. The accessory apparatus of claim 1 wherein the mounting bracket can be fixedly coupled to the frame.

8. The accessory apparatus of claim 1 wherein the mounting bracket is coupled to the frame by way of a four bar linkage.

9. The accessory apparatus of claim 1 further comprising:

a) a screw jack extending between the frame and the mounting bracket, the screw jack adjusting the height of the auger relative to the ground;

b) the motor is a hydraulic motor that is structured and arranged to be hydraulically coupled to the vehicle, the motor is located on one of the first or second ends;

c) the auger has a first portion of flighting, a second portion of flighting and a center portion located between the first and second portions, the flighting on the first portion being in a first direction and the flighting on the second portion being in a direction that is opposite to the first direction.

10. The mounting apparatus of claim 1 wherein the mounting bracket comprises a plate.

11. The mounting apparatus of claim 1 wherein the mounting bracket comprises a removable retainer to allow the mounting bracket to either be pivotally coupled to the frame when the retainer is removed and to allow the mounting bracket to be fixedly coupled to the frame when the retainer is in place.

12. An apparatus for backfilling a trench, comprising:

a) a vehicle;

b) a frame having first and second ends;

c) wheels rotatably mounted to the first and second ends of the frame, the wheels being structured and arranged to bear on ground beneath the frame;

d) an auger rotatably mounted to the first and second ends of the frame, the auger having a shaft with flighting extending radially outward therefrom, the shaft being oriented horizontally when the apparatus is in use and the auger having a height relative to the ground;

e) a motor coupled to the frame and to the auger, the motor causing the auger to rotate;

f) a mounting bracket pivotally coupled to the frame, the mounting bracket being removably coupled to the vehicle, wherein the frame can move so as to adjust the height of the auger relative to the ground.
