[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment: This embodiment discloses a crushing process for building ore in the weathered layer of a granite mine, comprising the following steps:

[0038] S1, coarse crushing of ore: the mined ore is put into the crusher box 100, and the coarse crushing mechanism 200 crushes the ore into coarse ore;

[0039] S2. Ore turning: During the coarse crushing of the ore, the ore is continuously turned by the turning mechanism 400;

[0040] S3, ore fine crushing: the coarse ore is discharged through the discharge port 102, and during the discharge process, the ore is further crushed by the fine crushing mechanism 300;

[0041] Among them, Figure 1-Figure 7As shown, the crushing box 100 of this embodiment is provided with a conical crushing groove 101, and the ore is crushed in the crushing groove 101. A discharge port 102 is provided below the crushing groove 101; a pair of guide plates 103 are symmetrically provided on the inclined surface of the crushing groove 101 for guiding the ore to the discharge port 102.

[0042] The coarse crushing mechanism 200 includes: an eccentric shaft 202, which is rotatably connected in the crusher box 100, and a rotating roller 203 is fixedly connected to the surface of the eccentric shaft 202; a crushing seat 201, which is slidably connected in the crusher box 100, and the crushing seat 201 is used to squeeze and crush the ore in the crushing slot 101, and a pushing frame 204 is fixedly connected to the crushing seat 201, and a rotating seat 205 rotatably connected to the rotating roller 203 is fixedly connected to the pushing frame 204; a driving motor 206, and the driving motor 206 drives the eccentric shaft 202 to rotate through a belt line and a pulley transmission mode. In this embodiment, the eccentric shaft 202 is driven to rotate by the driving motor 206, and the rotating roller 203 is driven to rotate, and then the crushing seat 201 is driven to reciprocate through the pushing frame 204, so that the ore in the crushing slot 101 is squeezed and crushed to form coarse ore. Due to the conical structure of the crushing slot 101, as the ore is continuously crushed, the ore with small particles will fall toward the discharge port 102.

[0043] like Figure 4-Figure 6As shown, the fine crushing mechanism 300 is arranged at the discharge port 102. After the ore is roughly crushed, it falls between the fine crushing mechanism 300 and the inner wall of the discharge port 102. The fine crushing mechanism 300 includes a pressure seat 301 and a movable plate 310. The movable plate 310 is fixedly connected to the push frame 204 through a bracket 311. A sleeve 305 is fixedly connected to the movable plate 310. A sleeve rod 306 movably connected to the sleeve 305 is fixedly connected to the pressure seat 301. A connecting block 308 is fixedly connected to the sleeve 305. A spring 308 is fixedly connected between the connecting block 308 and the pressure seat 301. 07; A pair of movable crushing plates 302 are symmetrically connected to the pressure seat 301, and the crushing plates 302 are squeezed and matched with the inner wall of the discharge port 102 to further crush the coarse ore; a sliding hole 303 that moves and matches with the crushing plates 302 is provided on the pressure seat 301, and a slider 304 that is slidably connected to the sliding hole 303 is fixedly connected to the crushing plate 302, and a connecting rod 309 is rotatably connected between the slider 304 and the connecting block 308; during the reciprocating movement of the push frame 204, the pressure seat 301 is driven to continuously reciprocate. When the pressure seat 301 approaches the discharge port 10 When the crushing plate 302 moves in the 2nd direction, the crushing plate 302 cooperates with the inner wall of the discharge port 102 to further squeeze and crush the coarse ore into fine ore, and during the movement, the moving plate 310, the pressure seat 301 and the crushing plate 302 simultaneously approach the discharge port 102. When the crushing plate 302 and the pressure seat 301 are unable to move due to resistance, the moving plate 310 continues to move forward, driving the connecting block 308 to move toward the pressure seat 301, the sleeve rod 306 shrinks in the sleeve 305, the spring 307 is compressed, and at the same time drives the two crushing plates 302 along the slide hole 303 The crushing plates 302 move away from each other and slide to both sides. During the sliding process, the crushing plates 302 grind and crush the coarse ore, further crushing the ore to achieve a better crushing effect. During the return journey, the movable plate 310 moves back first, and the sleeve 305 is reset under the action of the spring 307, driving the two crushing plates 302 to move closer to each other and return to their original positions. Then the movable plate 310 drives the pressure seat 301 and the crushing plate 302 to move back. Through the reciprocating motion of the fine crushing mechanism 300, the coarse ore is continuously crushed, so that the size of the crushed ore meets the requirements of quartz processing.

[0044] Preferably, a plurality of tooth blocks 312 are fixedly connected to the surface of the crushing plate 302. The tooth blocks 312 are provided to achieve a better crushing effect. A screen 313 is fixedly connected to the pressure seat 301. The screen 313 is arranged directly below the discharge port 102. When the pressure seat 301 moves back and forth, it drives the screen 313 to move back and forth, which can improve the screening efficiency of the ore. At the same time, the screen 313 also plays a role in supporting the coarse ore. The coarse ore falls through the discharge port 102 and falls on the surface of the screen 313. After the coarse ore is fully crushed by the fine crushing mechanism 300, the fine ore is discharged through the screen 313.

[0045] like Figure 1 and Figure 3As shown, the material turning mechanism 400 includes: a material turning frame 405, which is rotatably connected to the inside of the crushing trough 101, and the material turning frame 405 is arranged below the ore. When the material turning frame 405 rotates, it drives the ore to turn over, and a rotating member 403 is coaxially fixedly connected to the material turning frame 405; a first slide 401, which is fixedly connected to the pushing frame 204, and when the pushing frame 204 reciprocates, it drives the first slide 401 to reciprocate, and the first slide 401 is fixedly connected to a rack 402 that cooperates with the rotating member 403; a limiting wheel 404 is fixedly connected to the side of the crushing machine box 100 for limiting the rack 402, so that the rack 402 remains stable when moving.

[0046] Among them, Figure 7 As shown, the rotating member 403 includes: a ring gear 4031, which is meshed with the rack 402; a ratchet 4032, which is rotatably connected to the inner wall of the ring gear 4031, and the ratchet 4032 is coaxially fixedly connected to the tipping rack 405; a pawl 4033 cooperating with the ratchet 4032 is connected to the inner wall of the ring gear 4031, and an elastic member 4034 is connected between the inner wall of the ring gear 4031 and the pawl 4033; when the ring gear 4031 rotates forward, it can drive the ratchet 4032 to rotate, and then drive the tipping rack 405 to rotate; when the ring gear 4031 rotates reversely, it cannot drive the ratchet 4032 to rotate; through the structural design of the rotating member 403, the tipping rack 405 can only rotate in a reverse unidirectional direction, driving the ore to rotate in one direction, and the coarse crushing mechanism 200 can squeeze and crush the ore at different positions.

[0047] During specific implementation: when the coarse crushing mechanism 200 reciprocates, the push frame 204 reciprocates, driving the first slide 401 to reciprocate, and then driving the rack 402 to reciprocate. When the rack 402 moves forward, it drives the ring gear 4031 to rotate in the opposite direction, and the tipping frame 405 remains in a non-rotating state; when the rack 402 moves back, it drives the ring gear 4031 to rotate forward, drives the tipping frame 405 to rotate, and drives the ore to be turned over. The benefits of turning over are: first, adjusting the crushing position of the ore so that the crushing seat 201 can squeeze and crush the ore at different positions, thereby improving the crushing efficiency; second, the rotation of the tipping frame 405 plays a stirring role to avoid jamming; through the reciprocating motion of the coarse crushing mechanism 200, after each crushing of the ore, the tipping frame 405 is driven to turn the ore once, thereby improving the crushing efficiency of the ore.

[0048] like Figure 2As shown, the crushing box 100 is connected with an impact mechanism 500, and the impact mechanism 500 includes a rotating rod 506, which is rotatably connected to the surface of the crushing box 100, and a plurality of impact frames 501 are fixedly connected to the rotating rod 506, and the impact frames 501 are approximately U-shaped structures. The impact frames 501 are fixedly connected with impact hammers 502 for hammering the surface of the ore, and the impact hammers 502 are arranged above the crushing groove 101; the impact mechanism 500 also includes a second slide 505, and the second slide 505 is fixedly connected to the pushing frame 204. When the coarse crushing mechanism 200 reciprocates, the second slide 505 is driven to reciprocate. One end of the rotating rod 506 is fixedly connected to A fixed rod 503 is connected, and a connecting rod 504 is rotatably connected between the second slide 505 and the fixed rod 503, wherein the length of the fixed rod 503 should not be too long, so that the second slide 505 can drive the impact frame 501 to rotate a larger angle when it moves; the coarse crushing mechanism 200 drives the second slide 505 to move back and forth when it reciprocates, and the second slide 505 drives the rotating rod 506 to rotate back and forth, and the rotating rod 506 drives the impact frame 501 to rotate back and forth when it rotates back and forth, driving the impact hammer 502 to continuously impact the surface of the ore, so that the coarse crushing mechanism 200 drives the impact hammer 502 to impact the surface of the ore during the process of coarse crushing of the ore, thereby improving the crushing efficiency of the ore.
