[0048] The working principle and usage process of the present utility model: When using the present utility model, first, the materials to be crushed are put into the feeding port 1. One side of the feeding port 1 is fixedly connected with two second motors 7. Inside the feeding port 1, there are two crushing rollers 8. The output shaft of the second motor 7 is fixedly connected with one end of the crushing roller 8. By the rotation of the output shaft of the second motor 7, the crushing roller 8 is driven to rotate, and the ore entering through the feeding port 1 is crushed by the rotation of the crushing roller 8. After the ore is crushed, it will fall into the inside of the crushing chamber 2 along the opening at the top of the crushing chamber 2. Inside the crushing chamber 2, there is a filter sieve plate 11, and sliding grooves 13 are opened on the left and right sides of the crushing chamber 2. The filter sieve plate 11 is slidably connected with the crushing chamber 2 through the sliding grooves 13. Both ends of the filter sieve plate 11 are fixedly connected with connecting plates 12, and fixing blocks 9 are fixedly connected to the front and rear sides of the filter sieve plate 11. Pneumatic push rods 10 are fixedly connected to the left and right sides of the fixing blocks 9. One end of the output shaft of the pneumatic push rod 10 is fixedly connected with one side of the connecting plate 12. At this time, the pneumatic push rod 10 is started, and the output shaft of one pneumatic push rod 10 extends and the output shaft of the other pneumatic push rod 10 contracts to drive the filter sieve plate 11 to slide left and right. By the left and right sliding of the filter sieve plate 11, the crushed stones on the filter sieve plate 11 are driven to shake left and right to accelerate the filtering speed and prevent the crushed stones from accumulating and blocking the filter holes on the filter sieve plate 11. After the crushed stones are screened by the three-layer filter sieve plate 11, they will fall to the lowest end of the crushing chamber 2 and contact the side surface of the inclined block 17 arranged at the bottom end of the crushing chamber 2. By making the side surface of the inclined block 17 contact the screened stones, the stones are made to roll to the discharge port 4, and the crushed stones are discharged through the discharge port 4 for collection. When the crushed stones on the filter sieve plate 11 accumulate to a certain extent, the first motor 5 arranged on one side of the crushing chamber 2 is started. By the rotation of the output shaft of the first motor 5, the threaded rod 14 arranged inside the crushing chamber 2 and rotatably connected with the crushing chamber 2 is driven to rotate. By the rotation of the threaded rod 14, the push block 15 that is helically connected with the threaded rod 14 and whose bottom end slides on the top end of the filter sieve plate 11 is driven to move. By moving the push block 15, the push block 15 is driven to squeeze the large pieces of crushed stones remaining on the filter sieve plate 11 and move the crushed stones towards the flipping baffle 16 opened on one side of the crushing chamber 2, so as to make the remaining large pieces of crushed stones push open the flipping baffle 16 and be discharged to the outside for collection and secondary crushing in the follow-up. At the top end of the sliding groove 13 on one side of the crushing chamber 2, a water pump 20 is fixed. The output end of the water pump 20 is fixedly connected with a water delivery pipe 18. The other end of the water delivery pipe 18 extends into the inside of the crushing chamber 2 and is fixedly connected with the top end of the push block 15. A water spray head 19 is arranged at the rear side of the inclined surface of the push block 15. When the push block 15 starts to move, the water pump 20 is started. By the operation of the water pump 20, the water source is sent to the water spray head 19 through the water delivery pipe 18, and the water spray head 19 flushes the holes on the filter sieve plate 11. The crushed stones stuck in the holes of the filter sieve plate 11 are washed away by the high-speed water flow, and the dust generated during the crushing of limestone is reduced by the flushing of the water source.The support legs 3 provided at the bottom end of the crushing chamber 2 are used to fix the entire device to prevent the device from tilting, and the scraping blocks 6 provided inside the feed inlet 1 and in contact with the crushing rollers 8 are used to scrape the residual crushed stones and soil on the crushing rollers 8. The scraped soil and crushed slag will be discharged from the discharge slots 21 opened on both sides of the feed inlet 1.,

[0049] In the present utility model, components such as the first motor, the threaded rod, and the pneumatic push rod are all prior arts, and their working principles are the same as those of similar products on the market, so they will not be described in detail here.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
