[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] The crusher uses negative pressure ventilation when adding ore materials to be crushed on both sides of the crushing tank to extract dust generated when the ore falls and is crushed. At the same time, the water pump runs to pump water into the dispersion pipe and sprays it from multiple atomizing nozzles to settle the dust in the air near the hydraulic fan, so that part of the dust is directly dissolved in the water and discharged from the external exhaust pipe, greatly reducing the pollution to the surrounding environment and the harm to people's bodies.

Inclined plates 4 are symmetrically welded on both sides of the inner cavity of the crushing tank body 1, wherein the two inclined plates 4 are respectively located below the two feeding pipes 3, and the two inclined plates 4 are provided with inclined surfaces, so that the ore input from the two feeding pipes 3 can slide down along the inclined surfaces of the two inclined plates 4 and be crushed by the crushing barrel 7 and the crushing teeth 8. The two inner support shafts 6 are horizontally arranged in the inner cavity of the crushing tank body 1 and have the same height. Both ends of the inner support shaft 6 are rotatably connected to the crushing tank body 1, so that the motor 5 can drive the inner support shaft 6 to operate stably. The motor 5 and the water pump 11 need to be powered by external power facilities.

[0024] A water tank 9 is installed on one side of the top wall of the top cover 2, and an external pipe 10 communicating with the inner cavity of the water tank 9 is connected to the water tank 9, so that water can be added to the water tank 9 through the external pipe 10, wherein an air supply pipe 17 communicating with the inner cavity of the crushing tank body 1 is welded at the center of the top wall of the top cover 2, and the hydraulic assembly includes a hydraulic fan 18 installed in the air supply pipe 17, and a water pump 11 is installed on the side of the water tank 9 facing the air supply pipe 17, wherein the water pump 11 is connected with an output pipe 12, one end of the output pipe 12 passes through the water tank 9 and extends into the bottom of its inner cavity, and the other end passes through the top cover 2 and is connected to a dispersion pipe 13, wherein a plurality of atomizing nozzles 14 are installed at the bottom of the dispersion pipe 13, and the plurality of atomizing nozzles 14 are evenly spaced in the horizontal direction, so that the plurality of atomizing nozzles 14 can cover a larger range of dust sedimentation treatment;
