The side wall of the connecting block 8 is fixedly connected to a sliding column 10, which is slidably connected to the inside of the straight sliding groove 2. A coal mining assembly is provided on the outer wall of the connecting frame 7. The coal mining assembly is used to drive the pick to move. The coal mining assembly includes a connecting arm 11 and a roller 12.

A pick cutter 13 is provided on the outer wall of the roller 12, and a fixing plate 14 is fixedly connected to one side of the connecting arm 11.

[0033] Specifically, when it is necessary to adjust the depth and angle of the cutting tooth, the output end of the first motor 4 is used to drive the rotating rod 5 to rotate, and the rotating rod 5 transmits force to the connecting rod 6, thereby driving the connecting frame 7 to move. The movement of the connecting frame 7 acts on the connecting block 8, and the connecting block 8 drives the sliding column 1 9 connected to the side wall to slide in the arc groove 3. At the same time, the connecting block 8 also drives the sliding column 2 10 of the side wall to move in the straight sliding groove 2. These actions enable the connecting block 8 to flip, and then drive the connecting arm 11 to move on the outer wall through the connecting frame 7. The movement of the connecting arm 11 further affects the position of the roller 12 and the cutting tooth 13, thereby achieving the effect of adjusting the depth and angle of the cutting tooth.

The connecting arm 11 is subjected to force to drive the roller 12 and the cutting tooth cutter 13 on one side to move, thereby achieving the depth and angle of the cutting teeth. The effect of regulation is achieved, and then the cutter 13 is driven to rotate by the roller 12 for processing. During the processing, water can be sprayed on the roller 12 and the cutter 13 through the nozzle 21, and at the same time, the rotating column 17 is driven to rotate inside the support frame 16 through the output end of the second motor 15.
