Abstract

The utility model relates to the technical field of crushing devices, and discloses a crushing device for mines. The utility model solves the problem that larger ores in the ore cannot pass through the screening net, which will block the mesh holes and make smaller ores unable to fall, resulting in the ores piling up and inconvenience for subsequent ore processing. Through the arrangement of a crushing box, a motor B, a turntable, a fixed shaft, a clamping block, a movable plate and a limit frame, the ore enters the crushing box from a feed pipe for crushing, and the crushed ore falls onto the screening net for screening. The operation of the motor B drives the turntable to rotate, so that the fixed shaft rotates, and the fixed shaft moves up and down in the clamping block. When the fixed shaft is displaced left and right, it will move the clamping block left and right, so that the screening net moves left and right, and the ore at the upper end can be separated by the vibration generated by the movement, so that the larger ore will not block the smaller ore from falling.
