The screw threading machine 1 has two ends, one end is fixed to the bottom of the screw threading machine 1 and the other end is fixed to the bottom of the screw threading machine 11. The screw threading machine 1 has two ends, one end is fixed to the bottom of the screw threading machine 11 and the other end is fixed to the bottom of the screw threading machine 11. The screw threading machine 1 has two ends, the other end is fixed to the bottom of the screw threading machine 11. The screw threading machine 1 has a fixed end, and the screw threading machine 11 has a fixed end.

[0032] Example 2:

[0033] In order to make the device convenient for mining, a drill rod 4 is provided;

[0034] A drill rod 4 is provided at the bottom of the connecting ring 2, and a clamping piece 14 is fixedly connected to the top of the drill rod 4. A positioning piece 15 is fixedly connected to the outer surface of the drill rod 4. The outer surface of the clamping piece 14 is clamped with the inner wall of the closing piece 11. Therefore, the setting of the clamping piece 14 is to make the outer surface of the clamping piece 14 clamped with the inner wall of the closing piece 11 so that the drill rod 4 will not fall out of the device. The setting of the positioning piece 15 is to prevent the clamping piece 14 from shrinking into the device when the top of the positioning piece 15 collides with the bottom of the closing piece 11.

[0035] Example 3:

[0036] In order to ensure that the device has sufficient mining power, a fixing ring 5, a limiting ring 6 and a hammer body 7 are provided;

[0037] A fixing ring 5 is provided on the top of the cylinder 1, a limiting ring 6 is provided on the bottom of the fixing ring 5, a hammer body 7 is provided on the bottom of the limiting ring 6, the inner wall of the fixing ring 5 is fixedly connected to a cylinder rod 16, the bottom of the cylinder rod 16 is fixedly connected to a sleeve ring 17, the bottom of the fixing ring 5 is threadedly connected to the top of the docking plate 8, the top of the limiting ring 6 is fixedly connected to a reinforcing plate 18, a limiting rod 19 is fixedly installed on the bottom of the limiting ring 6, the inner wall of the limiting ring 6 is fixedly connected to the outer surface of the cylinder rod 16, a shock-absorbing pad 20 is fixedly installed on the top of the hammer body 7, a lifting ring 21 is fixedly connected to the top of the shock-absorbing pad 20, and the outer surface of the shock-absorbing pad 20 is fixedly connected to one end of the limiting rod 19. Therefore, the setting of the cylinder rod 16 is to allow the pressure oil of the hydraulic system to enter the cylinder through the pipeline when the device is working, pushing the cylinder rod 16 to Reciprocating motion. During this process, the cylinder rod 16 converts hydraulic energy into mechanical energy to provide power for the crushing operation. The cylinder rod 16 is connected to an external energy source and is started or shut down by an external controller. The socket ring 17 is set to be socketed with the lifting ring 21 so that the cylinder rod 16 can lift the hammer body 7. The reinforcement plate 18 is set to fix the limit ring 6 on the outer surface of the cylinder rod 16. The outer surface of the limit ring 6 is fixedly connected to the inner wall of the cylinder body 1. The limit rod 19 is set to ensure that the hammer body 7 does not shake when the cylinder rod 16 is lifted. The shock-absorbing pad 20 is set to absorb and disperse the vibration generated when the hammer body 7 is smashed down to protect the equipment from vibration damage. The lifting ring 21 is set to cooperate with the socket ring 17 to make the hammer body 7 easy to lift.

[0038] In the present invention, the working steps of the device are as follows:

[0039] First, at startup, the extension and contraction of the cylinder rod 16 will drive the hammer body 7 to move upward and downward. When the cylinder rod 16 moves upward, the compressed nitrogen chamber stores energy. When the cylinder rod moves downward, the stored energy is released and drives the hammer body 7 to hit the drill rod 4, so that the drill rod 4 hits the object to be broken at high speed, thereby achieving a crushing effect. During the operation of the breaker hammer, high-speed impact and vibration will generate huge energy. The shock-absorbing pad 20 can absorb and disperse this energy, thereby slowing down the vibration of the breaker hammer. The limit rod 19 can ensure that the hammer body 7 remains vertical during the upward and downward processes.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
