[0014] like Figures 1 to 3As shown, a crushing device for gold, silver, lead and zinc mine mining comprises a crushing box 1, in which two crushing rollers 2 are rotatably connected and meshed with each other, a hopper 3 is fixedly installed on the top of the crushing box 1 and corresponds to the middle position of the two crushing rollers, and also comprises a buffering and anti-blocking mechanism and a dust reduction mechanism arranged on the hopper 3, the buffering and anti-blocking mechanism comprises a driving assembly, two buffer plates 4 and two rotating shafts 5, the two buffer plates 4 are symmetrically arranged and the upper ends are respectively hinged on the inner walls of the hopper 3 on both sides of the bottom, and a buffer spring 6 is fixedly installed between the lower end of the buffer plate 4 and the inner wall of the hopper 3; when the ore in the hopper 3 is not blocked, the cooperation of the buffer plate 4 and the buffer spring 6 can play the role of buffering and guiding material, avoiding the frequent high impact force generated by the ore falling at a higher speed, which may cause impact on the conical bottom surface of the hopper 3 and cause deformation, thereby improving the service life of the hopper 3 and reducing the maintenance cost and replacement frequency of the equipment.

[0015] The front and rear ends of the two rotating shafts 5 are both equipped with bearings, which are rotatably connected to the front and rear side walls of the hopper 3 through the bearings and are respectively located on the lower sides of the two buffer plates 4. A plurality of cams 7 are sequentially mounted on the rotating shaft 5, and the cams 7 are arranged in coordination with the buffer plates 4. The driving assembly is installed on the hopper 3 and can drive the rotating shaft to rotate; when the raised end of the cam 7 contacts the lower surface of the buffer plate 4, the buffer plate 4 is lifted upward, and when the raised end of the cam 7 does not contact the buffer plate 4, the buffer plate 4 automatically falls, and then with the reciprocating rotation of the cam 7, the vibration effect of the buffer plate 4 is realized, thereby playing the role of vibrating the material, avoiding the blockage of ore in the hopper 3, and ensuring that the hopper 3 can discharge the material normally.

[0016] The dust reduction mechanism includes a water reservoir 8, a water pump 9 and an atomizing nozzle 10. The water reservoir 8 is arranged on the rear side of the crushing box 1. The water pump 9 is fixedly installed on the inner bottom wall of the water reservoir 8 and the output end is fixedly connected to the atomizing nozzle 10 through a water pipe. The atomizing nozzle 10 is arranged on the inner wall of the hopper 3; the water flow is transported to the inside of the atomizing nozzle 10 along the water pipe, and the atomizing nozzle 10 sprays the atomized water source onto the top surface of the hopper 3 to prevent dust from spreading outward.

[0017] The driving assembly includes a low-speed motor 11 and two sprockets 12. The two sprockets 12 are respectively mounted on the outer ends of the two rotating shafts 5. The two sprockets 12 are connected by the same chain transmission. The low-speed motor 11 is installed on the outer side of the hopper 3 and the output shaft is fixedly connected to the outer end of any rotating shaft 5.

[0018] A discharge port is provided through the bottom of the crushing box 1, and legs are symmetrically installed at the bottom of the crushing box 1.

[0019] The specific operation process of the utility model is as follows:

[0020] When the ore in the hopper 3 is blocked, the low-speed motor 11 is started to rotate, and the sprocket 12 and the chain cooperate to drive the rotation of the rotating shaft 5 and the cam 7 on the rotating shaft 5. When the raised end of the cam 7 contacts the bottom of the buffer plate 4, the buffer plate 4 is lifted up. When the raised end of the cam 7 does not contact the buffer plate 4, the buffer plate 4 automatically falls, thereby realizing the vibration of the buffer plate 4, and shaking off the ore blocked at the bottom opening of the hopper 3, thereby achieving the effect of dredging, ensuring the normal feeding of the ore, improving the practicability of the device, and effectively preventing the blockage caused by excessive feeding of crushed stone and affecting the production efficiency. The atomizing nozzle 10 located on the inner wall of the hopper 3 is started to reduce the dust generated by the reciprocating swing of the buffer plate 4 and the falling and crushing of the ore.
