[0035] The auxiliary crushing mechanism 6 includes a support fixing pad 61, a fixing housing 62 fixed to the top of the support fixing pad 61, a servo motor 63 fixed to the inner bottom wall of the fixing housing 62, an eccentric metal wheel 64 fixed to the outer side of the output shaft of the servo motor 63, a fixing support pad 65 fixed between the inner walls of the two sides of the fixing housing 62, a return spring 66 connected to one end of the fixing support pad 65, a movable mounting pad 67 connected to one end of the return spring 66, a carbon steel connecting rod 68 fixed to one side of the movable mounting pad 67, a stainless steel plate 69 fixed to one end of the carbon steel connecting rod 68, a stainless steel column 611 fixed to one side of the stainless steel plate 69, a guide fixing housing 610 fixed to one side of the fixing housing 62, and the interior of the fixing housing 62... A through hole is provided, the size of which is adapted to the size of the stainless steel column 611. When the carbon steel connecting rod 68 moves the stainless steel plate 69, the stainless steel column 611 can move normally in the horizontal direction. A limit hole is provided inside the guide fixing housing 610, the size of which is adapted to the size of the stainless steel column 611. When the stainless steel column 611 moves, one end of the stainless steel column 611 can hit the outer wall of the main body 1 of the mining crusher. The support fixing pad 61 is fixedly connected to the main body 1 of the mining crusher. The fixing housing 62 is fixedly connected to the main body 1 of the mining crusher, which can ensure the stable assembly of the fixing housing 62. A connecting hole is provided inside the fixing support pad 65, the size of which is adapted to the size of the carbon steel connecting rod 68.

[0036] The closing mechanism 7 includes a rotating door 71, a metal handle 72 fixed to the outside of the rotating door 71, a rotating metal bracket 73 fixed to the outside of the rotating door 71, a positioning groove 78 inside the rotating metal bracket 73, a metal mounting sleeve 74 fixed to the outside of the main body 1 of the mining crusher, a rotating threaded column 75 rotatably connected to the inside of the metal mounting sleeve 74 via a rotating shaft, a positioning threaded sleeve 76 threadedly connected to the outside of the rotating threaded column 75, an anti-slip handle 77 fixed to the outside of the positioning threaded sleeve 76, the size of the positioning groove 78 being adapted to the size of the rotating threaded column 75, and the rotating metal bracket 73 being rotatably connected to the main body 1 of the mining crusher via a rotating shaft.

[0037] Working Principle: During material crushing, the material is fed into the main body 1 of the mining crusher from the feed hopper 3. Then, the rotor hammer disc drive motor 5 is started to drive the corresponding rotor hammer disc structure to rotate. The material is crushed by impact through the high-speed rotating rotor hammer disc. For some sticky and wet materials, the servo motor 63 inside the fixed shell 62 can be started during crushing. The output shaft of the servo motor 63 drives the eccentric metal wheel 64 to rotate. When the eccentric metal wheel 64 rotates, it can push the movable mounting pad 67 to move horizontally. After the movable mounting pad 67 moves, it is reset by the elastic force provided by the return spring 66. When the movable mounting pad 67 moves, it can cause the stainless steel plate 69 and the guide fixed shell 610 to move back and forth, so that the guide fixed shell 610 intermittently impacts the outer wall of the mining crusher main body 1. The intermittent impact reduces the material's impact during crushing. The residence time within the main body 1, combined with the rotor hammer disc drive motor 5 driving the rotor hammer disc to impact and crush the material, prevents clogging through a dynamic structure, and can effectively crush ores with high moisture content or high viscosity, improving the crushing effect; this device is equipped with a closing mechanism 7. When it is necessary to open the rotating door 71 on the outside of the main body 1 of the mining crusher, the anti-slip handle 77 can be held to drive the positioning threaded sleeve 76 to rotate, allowing the positioning threaded sleeve 76 to disengage from the outside of the rotating threaded column 75, thereby releasing the obstruction and limitation of the positioning threaded sleeve 76 on the rotating metal bracket 73. Then, the metal handle 72 can be pulled to open the rotating door 71, making the rotating door 71 easy to open. Moreover, the opening and closing locking operations are relatively simple, and the internal materials of the cavity can be quickly opened for cleaning or parts replacement, reducing downtime.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
