[0017] Beneficial effects of the present invention: By arranging the cooperation of parts such as the bidirectional threaded screw and the like, when the screened material needs to be crushed for the second time, the feed roller stops rotating, the second drive motor starts, and the output end of the second drive motor drives the bidirectional threaded screw to rotate, thereby driving the two sliding seats to drive a first drive motor to move toward each other, so that the two crushing rollers can move toward each other, thereby reducing the gap between the two crushing rollers, eliminating the need for the staff to transfer the material multiple times for fine crushing, thereby improving the overall crushing effect of the device; By setting the cooperation of the nozzle and other parts, the air inlets of the two air inlet pipes can be connected to the external air supply pump. When the crushing roller is crushing, the air supply pump conveys gas to the inside of the air inlet pipe, which can be sprayed out through the nozzle. Since the two first baffles are initially tilted, the sprayed gas can form a composition at the edge of the crushing roller and the crushing box. At the same time, the sprayed high-pressure gas can prevent the material from sliding to the edge of the crushing roller and the crushing box. The sprayed high-pressure gas can slightly push the material to concentrate in the center area of ​​the crushing roller, thereby improving the crushing efficiency. By setting up the cooperation of the first baffle and other parts, the first baffle with a slight amplitude adjustment is always located on one side of a crushing roller and protects its edge. In the process of the two crushing rollers moving toward each other to reduce the gap for secondary crushing, the position of the crushing roller changes. If the position of the first baffle is fixed, there will be a protective gap between the edge of the crushing roller and the crushing box. Materials may enter these gaps, causing the equipment to get stuck or wear. The first baffle is slightly adjusted with the movement of the crushing roller, which can continuously form a protective barrier at the edge of the crushing roller, prevent materials from entering unnecessary areas, ensure the normal operation of the equipment, and extend the service life of the equipment. By setting the position adjustment component, the other first baffle can be adjusted greatly, so that the material that needs secondary crushing can be fed into the space between the two crushing rollers at a close distance. During the secondary crushing, accurate feeding is very important. The first baffle with a large adjustment can flexibly adjust the feeding position according to the change of the gap between the crushing rollers, so that the material falls into the crushing area more accurately, and the crushing efficiency is improved. This helps to reduce the ineffective movement of the material in the crushing box, so that more materials can be crushed in time and effectively, thereby improving the capacity of the entire crushing process; By setting up the cooperation of parts such as the second baffle, when the other first baffle is adjusted significantly, the second baffle at its bottom is driven by the large-arc arc rack to rotate significantly and be tilted between the two crushing rollers to achieve precise feeding. This precise feeding method can ensure that the material enters between the crushing rollers at a suitable angle and position, avoids the material from being scattered outside the crushing area, and improves the utilization rate of the material. At the same time, the inclined second baffle can also play a certain guiding role on the material, making the material more orderly when entering the crushing roller, further improving the crushing effect.

The feed roller 25 is driven to rotate by the servo motor, so that the chemical raw materials to be crushed can be intermittently dropped between the two crushing rollers 19. The two first drive motors 2 drive a crushing roller 19 to rotate respectively. The chemical raw materials that fall to the top are crushed by the two crushing rollers 19 rotating in opposite directions. The crushed materials fall to the top of the vibrating screen 24.

[0034] Reference Figure 1 to Figure 10 , a jet guard is located inside the feed shell 9 and is used to prevent the material from splashing onto the edge of the feed shell 9. The jet guard includes two first baffles 20 arranged inside the crushing box 8. Two air inlet pipes 16 are fixedly connected to the inside of the crushing box 8.

At the same time, the sprayed high-pressure gas can prevent the material from sliding to the edge of the crushing roller 19 and the crushing box 8. The sprayed high-pressure gas can slightly push the material to concentrate to the center area of ​​the crushing roller 19, thereby improving the crushing efficiency.

[0035] Reference Figure 1 to Figure 10, a secondary return piece is located on one side of the feed shell 9 and is used for secondary crushing of the filtered material.

In the process of the two crushing rollers 19 moving toward each other to reduce the gap for secondary crushing, the position of the crushing roller 19 changes. If the position of the first baffle 20 is fixed, there will be a protective gap between the edge of the crushing roller 19 and the crushing box 8, and materials may enter these gaps, causing the equipment to get stuck or wear. The first baffle 20 moves with the crushing roller 19 and is slightly adjusted, which can continuously form a protective barrier at the edge of the crushing roller 19, preventing materials from entering unnecessary areas, ensuring the normal operation of the equipment, and extending the service life of the equipment. The two arc-shaped racks 39 are arranged with a large arc and a small arc. When the other first baffle 20 is adjusted greatly, the second small spur gear 38 contacts the arc-shaped rack 39 with a large arc, so that the arc-shaped rack 39 drives the second small spur gear 38 to drive the second baffle 29 to rotate greatly through the toggle shaft 32, so that the second baffle 29 at the bottom of the other first baffle 20 can be tilted and aligned between the two crushing rollers 19 after the large-scale adjustment, so as to accurately feed the material. Since the arc-shaped racks 39 have a large arc and a small arc, the second baffle 29 at the bottom of the first baffle 20 adjusted slightly is slightly opened, so as to adjust the blowing angle; Another first baffle 20 is adjusted greatly, and can feed the material that needs secondary crushing into the space between the two crushing rollers 19 at a close distance. During the secondary crushing, accurate feeding is very important. The first baffle 20 that is adjusted greatly can flexibly adjust the feeding position according to the change of the gap between the crushing rollers 19, so that the material falls into the crushing area more accurately, and the crushing efficiency is improved. This helps to reduce the ineffective movement of the material in the crushing box 8, so that more materials can be crushed in time and effectively, thereby improving the capacity of the entire crushing process; When the other first baffle 20 is adjusted significantly, the second baffle 29 at its bottom is driven by the large-radius arc-shaped rack 39 to rotate significantly and be tilted between the two crushing rollers 19 to achieve precise feeding. This precise feeding method can ensure that the material enters between the crushing rollers 19 at a suitable angle and position, avoids the material from being scattered outside the crushing area, and improves the utilization rate of the material. At the same time, the inclined second baffle 29 can also play a certain guiding role on the material, making the material more orderly when entering the crushing roller, further improving the crushing effect.
