When the crusher 1 is used for crushing materials, a large amount of water needs to be injected into the water tank 415 in the box body 402 through the water injection holes, an external water pipe can be directly connected with the water injection holes for water injection, the tightness of the water tank 415 only needs to be ensured when the crusher is used at a later stage, after the water tank 415 is filled with water, the discharge hopper 702 can be adjusted according to the actual material receiving condition, when the distance required to be conveyed after the crushed materials are discharged is long, only the pull plate 904 needs to be pulled, the pull plate 904 drives the positioning block 907 on the moving block 905 to be released from the inside of the positioning groove 903 after the limit of the positioning block 907 on the moving block 905 is released, the extension hopper 901 can be pulled out at the moment, so that the discharge hopper 702 is extended, the crusher is suitable for different discharging environments, the discharging work is convenient, when the extension hopper 901 needs to be contracted, only the extension hopper 901 needs to be pushed upwards, and because the positioning block 907 and the positioning groove 903 are both in a right-angled triangle structure, therefore, only the unidirectional automatic retraction of the extension hopper 901 can be realized, but the automatic pulling-out can not be realized, so as to facilitate the adjustment of the extension hopper 901, the operation is convenient and fast, and because the discharge hopper 702 is rotatably connected with the base 2 through the rotating column 701, the limiting block 705 fixed on the discharge hopper 702 is also slidably connected with the base 2 through the arc-shaped limiting column 704 and the sliding chute 703, and the second spring 706 is sleeved outside the limiting column 704, therefore, when the crushed material falls on the discharge hopper 702, the discharge hopper 702 can also rotate and shake under the elastic force of the second spring 706, thereby further avoiding the condition that the falling material is piled up and blocked, so as to facilitate the discharge of the crushed material, because the flywheel 3 with uniform load of the flywheel motor rotates when the crusher 1 performs the crushing operation, because the collision block 401 with the arc-shaped structure is installed on the flywheel 3, therefore, the contact block 401 will rotate along with the flywheel 3, when the contact block 401 on the flywheel 3 rotates to the lowest end, the contact block will slide against the pressing plate 403 towards the inside of the box 402, because the piston 408 is fixedly connected to the bottom end of the pressing plate 403, the piston 408 can press the gas inside the gas tank 411 into the communicating groove 414 through the second check valve 413, and finally enter the inside of the water tank 415, at this time, the air pressure inside the water tank 415 is increased, the water inside the water tank 415 can be pressed into the inside of the fixed pipe 406 through the water outlet pipe 404 and the connecting pipe 405, and finally the water is atomized and sprayed out from the plurality of nozzles 407, so that the water spraying operation can be performed at the inlet of the crusher 1, that is, the humidity of the material can be increased, the crusher 1 can be conveniently crushed, the dust falling effect can be achieved, the crusher 1 is prevented from generating larger dust, the environmental pollution is avoided, and the environmental protection effect is achieved, and a water spray assembly is also arranged at the discharge port of the crusher 1, dust fall can be carried out on the discharge port, environmental protection is improved, when the abutting block 401 does not abut against the pressing plate 403 any more, the pressing plate 403 can rise under the action of the first spring 410, at the moment, the first check valve 412 is used for air inlet to supplement air so as to carry out continuous action, thereby overcoming the defect of insufficient external water pressure, when the air pressure of single pressing needs to be adjusted, only the stretching amount of the pressing plate 403 pressed by the abutting block 401 is needed to be adjusted, namely the stretching amount of the abutting block 401 is needed to be adjusted, when the stretching amount of the abutting block 401 needs to be adjusted, only the rotating shaft 501 needs to be rotated externally, because the worm 502 fixed on the rotating shaft 501 is meshed with the worm wheel 504 fixed at the bottom end of the screw 503, and the screw 503 rotated inside the flywheel 3 is in threaded connection with the abutting block 401 sliding inside the flywheel 3, therefore, when the rotating shaft 501 is rotated externally, the screw 503 can be driven to rotate, the pressing plate 403 can slide up and down, the extending amount of the contact block 401 can be adjusted, and the worm wheel 504 and the worm 502 have self-locking performance in transmission, namely, after the adjustment is finished, the self-locking can be realized, so that the subsequent use is convenient, and because the sliding rod 602 in the cuboid structure is also connected in the box body 402 in a sliding manner, and the hollow floating ball 603 is also fixedly connected at the bottom end of the sliding rod 602, when the water in the water tank 415 is enough, the sliding rod 602 can jack up the red alarm lamp 606 on the mounting block 605, so that people can know the water level condition in the water tank 415, so as to conveniently replenish water in time, and because the storage battery 604 is arranged in the fixing sleeve 601, the first contact 607 is arranged on the fixing sleeve 601, the second contact 608 is arranged on the mounting block 605, and the storage battery 604 is connected with the first contact 607 through an electric wire, the storage battery 604 is further in electric wire connection with an alarm lamp 606, the alarm lamp 606 is in electric wire connection with a second contact 608, therefore, when the water level inside the water tank 415 is low, the first contact 607 collides with the second contact 608 at this time, an electric loop is formed at this time, the alarm lamp 606 gives an alarm to remind a worker to perform water replenishing operation in time, the alarm sound of the alarm lamp 606 is greater than the crushing sound of the crusher 1, so that the worker at a distance can replenish water in time, and when the pressing plate 403 is pressed down by the abutting block 401, the pressing plate 403 can drive the pressing block 807 to press the pressing rod 801, when the pressing rod 801 slides downwards under the pressing action of the pressing block 807, the rack 805 on the sliding plate 802 is driven to be meshed with the gear 806 on the rotating column 701, so as to realize the rotation of the rotating column 701, at this time, the condition of the rotation and shaking of the discharging hopper 702 occurs, so that the shaking of the discharging hopper 702 can be avoided when the outflow materials are not enough to shake, and the shaking property can be generated, so that the discharging effect of the material is ensured.
