[0002] Material crushing is the process of using external force to split large solids into small solids, thereby controlling the size and shape of the materials. During crushing, it is necessary to use crushers and other equipment to process the production materials so that the materials are processed into small particles to facilitate the resource utilization and reduction of solids. When crushing materials, a feeding device is required to transport the materials to the processing equipment to ensure the processing efficiency of the equipment and the safety of the feeding process.

[0003] The prior art is a utility model with a publication number of CN219816598U, which discloses a crusher feeding device. The patent adopts a crusher body and a push plate, and a feed port is arranged at the upper end of the crusher body.

The two ends of the push plate are respectively movable and penetrate the two side ends of the crusher body, and a through hole is opened on the surface of the push plate to penetrate the push plate. The utility model drives the push plate to move through the movement of the slider, and drives the round rod to move through the movement of the contact plate, so that the spring is compressed by force, and the elastic reset effect of the spring is utilized to reset the push plate, the slider and the contact plate, and as the cam continues to rotate, the push plate reciprocates in the crusher body, and the reciprocating movement of the push plate pushes the crushed stones in the through hole, thereby alleviating the blockage, ensuring the stable operation of the crusher, and solving the problem that materials are accumulated at the feed port during the use of the crusher, causing the feed port to be blocked and interfering with the normal operation of the equipment.

[0004] The inventors have discovered in their daily work that in the process of assisting the material crushing equipment with the aid of a feeding device, there is an existing feeding device such as the above-mentioned one that uses horizontal movement to achieve unblocking of the feed port.
