[0020] Beneficial Effects

[0021] The present invention provides a high-efficiency feeding bulk material crusher. Compared with the prior art, it has the following beneficial effects:

[0022] (1) By setting up a material distribution component, the scattered materials can be collected by using a hopper, and the collected materials can be quantitatively and batch-transported through the circular plate, the groove and the discharge pipe. Then, through the action of the screw feeder, the collected materials are returned to the crusher body for crushing.

[0023] (2) By setting up a crushing unit and utilizing the meshing of two interlocking gears, the support rods on both sides drive the rollers to rotate in opposite directions, thereby crushing the collected materials so that the materials are processed into sizes of specified specifications or below, which facilitates the transportation, reprocessing and storage of the materials.

[0024] (3) By setting up a material storage unit and utilizing the reciprocating lifting motion of the push plate, the collected materials can be stored inside the material box and on the other side of the partition. Therefore, when the crusher body cannot process the scattered materials, the scattered materials can be stored in a unified manner, and the inclined surface on the top of the push plate can facilitate the diversion of materials during storage.

[0026] (5) By setting up a linkage structure, the toothed ring follows the rotation of the driving gear and meshes with the bevel gear, thereby driving the lead screw to rotate and compressing the torsion spring. The lead screw is then threadedly connected to the rack and the rack is meshed with the rotating gear, thereby driving the drum to wind the cable.
