At this time, the screw rod 20 is rotated, and the right end of the screw rod 20 is pushed The sliding block 16 slides to the right, so that the fixed seat 5 is pushed by the support rod 18 to rotate clockwise around the rotation axis 4, thereby realizing the angle adjustment of the cutting head 13. After the angle adjustment is completed, by rotating the screw rod 20, due to the sliding A third spring 19 is provided on the right side of the block 16, so that the slider 16 can slide slightly left and right, thereby starting a heavy shock absorption. At this time, the drive motor 6 is started, and the output shaft of the drive motor 6 drives the main shaft through the belt 8 transmission. When the main shaft 10 rotates and the main shaft 10 rotates, since the cross sections of the sliding piston 21 and the sliding cavity 23 are rectangular, the cutting head 13 is driven to rotate by the main shaft 10 to start construction, and by setting the guide rod 11, the main shaft is not excessively increased. At the same time of 10 weight, the ability of the main shaft 10 to resist lateral force can be improved to a certain extent. At the same time, the first spring 12 and the second spring 22 are provided to make the cutting head 13 receive a certain spring force when sliding along the main shaft 10. So as to play the second damping effect; the utility model is suitable for a damping device of a fully mechanized coal mining machine. By setting a belt drive to drive the main shaft 10 to rotate, the belt drive itself will slip when the torque is too large, thereby It avoids the situation that the drive motor 6 is damaged when the cutting head 13 is locked, and the device is provided with the first spring 12, the second spring 22 and the third spring 19 for shock absorption, which improves the shock resistance of the entire device. The effect is suitable for promotion and use.
