[0036] Please refer to the appendix Figure 2 -appendix Figure 4 , a controller 27 is fixedly connected to the left side of the hollow outer shell 3.

The top end of the second threaded rod 16 is fixedly connected to a first turning handle 25, and the left end of the first threaded rod 14 is fixedly connected to a second turning handle 31;
[0037] Specifically, both the first turning handle 25 and the second turning handle 31 can help the user to operate the device.

Among them, the model of the water pump 201 is DG270-150, and the model of the asynchronous motor 8 is H100-280.
[0038] Working principle: When the vibration of the crusher is too large, stop the asynchronous motor 8, and then rotate the second handle 31 so that the first threaded rod 14 rotates together, driving the sliding plate 13 with the clamping groove 12 to move leftward. After disengaging from the engagement with the guide block 17, rotate the first handle 25 to drive the second threaded rod 16 to rotate, thereby moving the sliding block 18 upward to adjust the position of the guide block 17, and then adjust the angle of the fixed jaw 11, and further adjust the gap between the fixed jaw 11 and the clamping groove 12, adjust the crushing degree to reduce the vibration. Then start the asynchronous motor 8. When the power flywheel 7 drives the driven flywheel 5 to rotate through the belt 4, the moving jaw 10 performs jaw crushing along the movement track of the eccentric wheel 9. At the same time, the sliding column 21 rotates on the rotating rod 19 and continuously squeezes the spring 22 to slide in the hollow column 23, so as to reduce the vibration of the moving jaw 10 during crushing and transmit it to the hollow housing 3;
[0039] When performing long-term crushing or when there is sediment on the stone material, start the water pump 201 to pump water from the return water tank 206 into the water pipe 202 and then spray it out from the nozzle 203. At the same time, the sprayed water carries the crushed material flow out from the discharge port and passes through the filtration of the filter plate 204, so that the water flows into the return water tank 206 from the guide plate 205 to complete the water cycle.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
