Abstract

Apparatus for spreading granular material such as salt, cinders and the like in which the conveyor is an assembly insertable into the hopper and the drive for the conveyor and spreader are mounted on the assembly. The conveyor assembly rests on the bottom wall of the hopper. The discharge of material starts at the rear wall of the hopper. The result is a reduction in the weight, height and length and a lowering of the center of gravity of the apparatus.

Claims

1. Apparatus for spreading granular materials, comprising a hopper adapted to be mounted on and extend longitudinally of a truck or trailer, said hopper having a substantially flat bottom wall, side walls diverging outward and upward from longitudinal edges of the bottom wall and end walls connected between said bottom wall and said side walls, one of said end walls having an opening registering with said bottom wall through which material may be removed,

a conveyor housing with its inboard end insertable into the hopper through said opening and with its outboard end projecting outward from said opening, said housing having a bottom wall resting on the bottom wall of the hopper, a drag bar conveyor in said housing with bars extending between two chains, the bars of the lower reach of the conveyor riding on the bottom wall of the housing and moving toward and through said opening, means for protecting the conveyor from the overlying weight of material,

a distributor for the material, and a chute leading from the housing adjacent the bottom wall of said hopper to said distributor.

2. The structure of claim 1 having a motor on the outboard end of the housing for driving the conveyor.

3. The structure of claim 1 having brackets fastened to said one end wall for holding the housing in place.

4. The structure of claim 1 in which the means for protecting the conveyor comprises a top wall of said housing.

5. The structure of claim 1 in which the housing has side walls with openings for flow of material into the housing.

6. The structure of claim 1 having a motor supported on the outboard end of the housing for driving the distributor.

7. The structure of claim 1 having an outwardly diverging outlet from the conveyor to the chute.

8. The structure of claim 1 in which the bars of the lower reach pass over a discharge opening in the bottom wall of the housing.

9. The structure of claim 8 in which the opening is V shaped with the bars of the lower reach first passing over the apex of the V.

10. The structure of claim 1 in which the distributor has a disc with vanes on its upper surface and a hollow cone mounted on said vanes and having an open top receiving material from said chute, said cone diverging outward toward said disc and holding material on said disc when the disc is not rotating.
