The drill 19 can tunnel the coal layer and break the coal, but some coal layers can collapse due to losing support, the collapsed coal can contain large-volume coal, the push plate 14 is difficult to push to the conveying device due to rotation, even the push plate 14 can be blocked from moving to block, the coal is hammered to break through the hammer 15 on the push plate 14 every time the hammer rotates, so that the push plate 14 can push the broken coal to the conveying device, when the coal is difficult to be hammered and broken once, the hammer 15 and the push plate 14 are blocked by the coal, so that the corresponding push plate 14 drives the hammer 15 to move around the hinge shaft of the hammer so as to bypass the coal block, after the coal block is bypassed, the push plate 14 and the hammer 15 reset under the driving of the torsion spring, the other push plate 14 drives the hammer 15 to continue to hammer the coal block, and each hammer 15 can crush the coal block again in the rotating process, the coal pushing plate is convenient to convey and transport, and meanwhile, the breaking hammer 15 can vibrate when hitting the coal blocks, so that coal at the top of the pushing plate 14 is easy to fall down and is not easy to condense into scale, and the phenomenon of difficulty in cleaning is caused.

Furthermore, as shown in the figure, the top of the push plate 14 of the embodiment is fixedly connected with a cleaning module 41 on one side close to the hinge shaft, and the cleaning module 41 can clean the top of the vertical shaft 11 when rotating. Because the top area of the vertical shaft 11 is large, a large amount of coal is easily accumulated, and when the push plate 14 rotates around the hinged shaft, the cleaning module 41 can be driven to rotate so as to clean the top of the vertical shaft 1, so that the phenomenon that the top of the vertical shaft is accumulated for a long time to cause scale condensation and is difficult to remove is prevented.
