[0050] Next, the worker places the coal gangue on the conveyor belt 4, and the conveyor belt 4 conveys the coal gangue to the feed port 31 and enters the crushing chamber 7 in the crushing box 3. After a proper amount of coal gangue is put in, the drive motor 2 41 stops and the conveyor belt 4 stops feeding.

[0051] Then, the first hydraulic telescopic shaft 8 is started, and the first hydraulic telescopic shaft 8 drives the movable plate 10 to move downward, and the movable plate 10 drives the pressure plate frame 12 to move downward, and the baffle frame 13 first contacts the bottom of the crushing chamber 7, and the movable plate 10 continues to move downward, and the pressure plate frame 12 begins to squeeze the coal gangue.

[0052] When the crushing space formed by the pressure plate frame 12, the baffle frame 13 and the crushing chamber 7 is small enough, the second hydraulic telescopic shaft 14 is started, and the drive motor 15 is started synchronously, the drilling head 154 passes through the passage 121, the drive motor 15 drives the drilling head 154 to rotate, and the second hydraulic telescopic shaft 14 drives the drilling head 154 to move downward and penetrate into the coal gangue. The drive motor 15 drives the first rotating rod 151 to rotate, the first rotating rod 151 drives the conveyor belt 152 to rotate, and the conveyor belt 152 drives the second rotating rods 153 on both sides to rotate, thereby driving the stone striking knife 155 to rotate and start to crush the coal gangue.

[0053] Finally, the drive motor 4 61 is started, and the drive motor 4 61 drives the electric door 6 to rise, and the crushed coal gangue is poured out through the discharge port 33, and the coal gangue leaked during the crushing process is also discharged through the discharge port 32 to prevent damage to the device.
