[0044] In this embodiment, the vertical shaft impact crusher used in mining engineering, when in use, stone materials are put into the vertical shaft impact crusher body 102, and the materials are crushed by the vertical shaft impact crusher body 102 under the action of centrifugal force, and the crushed materials are discharged through the discharge port of the vertical shaft impact crusher body 102 and fall on the screen plate 107; in this process, the motor 202 is started, and then the first bevel gear 203 is driven to rotate, and the second bevel gear 204 is driven to rotate through the first bevel gear 203, and the second bevel gear 204 can drive the connecting shaft 205 to rotate, and the connecting shaft 205 drives the two The rotating disk 206 rotates, and the rotation of the rotating disk 206 drives the movable pin 207 to rotate, and the movable pin 207 drives the movable rod 208 to swing back and forth. At the same time, the movable rod 208 drives the connecting rod 209 to move back and forth; the connecting rod 209 drives the U-shaped frame 105, the driving wheel 104, the screen plate 107 and the side baffle 106 to move synchronously, and the driving wheel 104 slides in the track groove provided in the crossbeam frame 103. By cooperating with the track groove provided in the crossbeam frame 103, the U-shaped frame 105, the side baffle 106 and the screen plate 107 can be limited and moved, thereby ensuring the movement stability of these components;

[0045] The side baffle 106 drives the screen plate 107 and the guide plate 108 to move back and forth, and the broken stones are screened through the screen plate 107. The qualified materials are discharged through the screen holes of the screen plate 107, and the unqualified materials are discharged along the inclined surface of the screen plate 107. By adding an advanced screening system, it is ensured that the broken materials can be effectively screened before being discharged, so that only materials that meet the particle size requirements are discharged, which improves the quality and uniformity of the discharged materials. The larger material particles after screening are crushed for the second time, which avoids the mixed discharge of larger particles and qualified materials, thereby improving the use effect and meeting the needs of high-quality production;

[0046] A first conveyor belt mechanism is provided at the bottom of one side of the guide plate 108, and its output end corresponds to the top of the vertical shaft impact crusher body 102. At the same time, a second conveyor belt mechanism is provided below the screen plate 107. The screened large particle materials are put on the first conveyor belt mechanism and transported to the vertical shaft impact crusher body 102 for secondary crushing through the mechanism. The qualified material particles screened by the screen plate 107 fall on the second conveyor belt mechanism, which transports the qualified materials to the designated area. The first conveyor belt mechanism and the second conveyor belt mechanism are both fixedly connected to the ground.

[0047] When the connecting rod 209 moves back and forth, it drives the piston rod 301 to move back and forth in the piston cylinder 302, compresses the gas inside the piston cylinder 302 into the connecting pipe 304, and transports it to the exhaust pipe 306. Through the exhaust port of the exhaust pipe 306, the gas is discharged to the position of the crossbeam frame 103 to blow away the dust accumulated in the track groove, ensuring that the driving wheel 104 is not affected when sliding in the track groove opened by the crossbeam frame 103, thereby improving the use effect of the device;

[0048] A sealing ring is fixedly installed at the position of the piston rod 301 inside the piston cylinder 302 to enhance the sealing performance of the piston rod 301 and the piston cylinder 302 and improve the gas compression effect;

[0049] One end of the piston cylinder 302 is provided with a one-way air valve 303 as a one-way air intake valve, and the one-way air valve 303 on the blocking disk 305 is used as a one-way exhaust valve. These two sets of one-way air valves 303 ensure that the movement of the piston rod 301 is not affected;

[0050] As the U-shaped frame 105 reciprocates, it drives the V-shaped rod 403 to move. When the U-shaped frame 105 moves to one end, the V-shaped rod 403 (with a V-shaped structure design) can flexibly squeeze and move the L-shaped guide rod 401 on one side upward while moving. At the same time, the L-shaped guide rod 401 drives the cross plate 404 to slide on the limit pin 405. When the side baffle 106 moves to the other end, it squeezes the L-shaped guide rod 401 on the other side. When the squeezing of the L-shaped guide rod 401 is released, it automatically falls due to gravity. Through the up and down movement of the L-shaped guide rod 401, one end of the L-shaped guide rod 401 is pounded up and down at the discharge port of the vertical shaft impact crusher body 102 to dredge the discharge port, reduce blockage, and further improve the use effect of the device.

[0051] At the same time, when the L-shaped guide rod 401 moves, a sleeve 402 is installed on its surface through a bearing. When the V-shaped rod 403 squeezes the L-shaped guide rod 401, the setting of the sleeve 402 increases the smoothness of the squeezing of the L-shaped guide rod 401 and reduces the squeezing friction, thereby improving the use effect of the device.

[0052] It should be noted that: the power equipment involved in this product is powered by an external power supply. The solution also provides an electric control cabinet, which is arranged on the bracket 101. When in use, each power-consuming device can be started and operated through the electric control cabinet.
