[0014] Preferably, the nut ring is fixedly connected to the movable seat, the cleaning board and the conveyor belt are perpendicular to each other, and the collecting box corresponds to the position of the movable seat.

[0015] Preferably, the mounting block is engaged with the movable seat via a mounting groove, and the connecting plate is fixed to the movable seat via bolts.

[0016] Compared with the prior art, the utility model provides a coal mining and conveying device having the following

[0017] Beneficial effects:

[0018] The utility model can drive the lead screw to rotate through the transmission motor, and the rotating lead screw can transmit the nut ring and the moving seat in the vertical direction, so that the cleaning rough plate can be moved up to the position in contact with the conveyor belt, which is convenient for wiping the coal on the conveyor belt. At the same time, the wiped coal can fall into the collection box for collection, thereby avoiding the problem of lack of cleaning structure in the device. Usually, when using the conveyor belt to transport coal slag, the coal slag will adhere to the conveyor belt. After a long time, the outer wall of the conveyor belt will adhere to a lot of coal slag, which correspondingly reduces the use effect and efficiency of the conveyor belt.
