the coal cleaning shovel is hinged with the movable frame, two ends of the hydraulic cylinder I are respectively connected with the coal cleaning shovel and the movable frame, the coal cleaning shovel, the movable frame and the hydraulic cylinder I form a three-link mechanism, two ends of the hydraulic cylinder II are respectively connected with the movable frame and the fixed frame, the hydraulic cylinder III is respectively connected with the fixed frame and the groove to form a four-link mechanism, and two ends of the hydraulic cylinder IV are respectively connected with the movable frame and the hinged groove;

the coal cleaning shovel, the movable frame and the fixed frame are all in a left-right symmetrical structure;

the coal cleaning shovel is of a bucket type;

the number of the hydraulic cylinders I and III is two.

Further, the fixing frame can be matched and connected with the groove.

Furthermore, the coal cleaning shovel can rotate upwards within the range of alpha and rotate downwards within the range of beta to be controlled by the expansion of a piston rod of the hydraulic cylinder I.
