The raw materials are conveyed by the conveying component and preliminarily crushed at the same time, so that the larger chemical raw materials are cut into smaller pieces by the spiral blades 10 during the conveying process, and then move to the crushing component through the guide plate 5. Since the crushing component adopts crushing rollers 12 rotating in opposite directions, the raw materials passing through the crushing component can be fully crushed to ensure the crushing effect. The filter plate 6 can filter the crushed raw materials, and the striking component can apply vibration to the filter plate 6 to move the raw materials that do not meet the specifications to the first discharge port 7, so that they can be processed again, thereby ensuring the quality of the discharge.

[0020] Further optimization scheme, the conveying assembly includes a plurality of parallel conveying shafts 9 rotatably connected to the inner wall of the conveying box 2, a spiral blade 10 is fixedly connected to the conveying shaft 9, and the spiral blades 10 at both ends of the conveying shaft 9 rotate in opposite directions. A conveying motor 11 for controlling the rotation of the conveying shaft 9 is installed on the outer wall of the conveying box 2, and the first feed hopper 3 is correspondingly arranged in the middle of the conveying shaft 9, and two openings 4 are provided, and the openings 4 are opened on the side of the top wall of the box body 1.

[0021] Furthermore, the plurality of conveying shafts 9 may be connected by transmission means such as a synchronous belt, a sprocket chain, or a gear, so that the conveying motor 11 can drive all the conveying shafts 9 to rotate.

[0022] Furthermore, a plurality of arc grooves are provided on the top wall of the box body 1 corresponding to the conveying shaft 9, and the arc grooves are adapted to the spiral blades 10, so as to reduce the dead angle of conveying and fully convey the raw materials.

[0023] Further optimized solution: The crushing assembly includes a crushing roller 12 rotatably connected to the inner wall of the box body 1. The two crushing rollers 12 rotate towards each other. A crushing motor for controlling the rotation of the crushing roller 12 is fixedly connected to the outer wall of the box body 1.

[0024] Furthermore, the central axes of the two crushing rollers 12 penetrate through the side wall of the box body 1 and are fixedly connected with transmission gears. The two transmission gears are meshed, so that the crushing motor can drive the two crushing rollers 12 to rotate synchronously towards each other. This technology is a conventional technical means and will not be elaborated here.

[0025] Further optimized solution: An installation block 15 is fixedly connected to the side wall of the box body 1. The installation block 15 is arranged corresponding to the filter plate 6. One side of the installation block 15 close to the filter plate 6 is an arc surface. One end of the filter plate 6 far from the first discharge port 7 is slidably matched with the installation block 15. A first limit block 16 and a second limit block 17 are fixedly connected to the arc surface of the installation block 15. The filter plate 6 is located between the first limit block 16 and the second limit block 17 and is arranged in contact with the second limit block 17. A return spring 18 is fixedly connected between the first limit block 16 and the filter plate 6. The swinging range of the filter plate 6 is limited by the first limit block 16 and the second limit block 17. The return spring 18 can cooperate with the hitting assembly to make the filter plate 6 move up and down, so as to fully filter the materials.

[0026] Further optimized solution: The hitting assembly includes a rotating shaft 19 rotatably installed on the inner wall of the box body 1. An installation roller 20 is fixedly connected to the rotating shaft 19. Two symmetrically arranged installation seats 21 are fixedly connected to the installation roller 20.

The other end of the hitting block 23 penetrates through the installation seat 21 and is located outside the sliding groove 22. The hitting block 23 is arranged corresponding to the bottom of the filter plate 6. A hitting motor is fixedly connected to the outer wall of the box body 1. The output shaft of the hitting motor is fixedly connected to the rotating shaft 19. The hitting motor drives the rotating shaft 19 to rotate, and then drives the two installation seats 21 on the installation roller 20 to rotate, so that the two hitting blocks 23 continuously hit the bottom of the filter plate 6, enabling the filter plate 6 to fully filter the raw materials, and at the same time making the raw materials staying on the filter plate 6 gather towards the first discharge port 7, which is convenient for collection and treatment.

[0027] For a further optimized solution, the two flow guiding plates 5 are inclined, the top end of the flow guiding plate 5 is correspondingly arranged with the opening 4, and the bottom end of the flow guiding plate 5 is correspondingly arranged with the crushing rollers 12. This facilitates the transportation of the raw materials coming out of the opening 4, enabling them to move between the two crushing rollers 12 for easy crushing.

[0028] For a further optimized solution, a second feed hopper 25 is connected to the side wall of the box body 1, and the connection between the second feed hopper 25 and the side wall of the box body 1 is located above the flow guiding plate 5. This facilitates the re-crushing of the raw materials that do not meet the specification requirements after the previous crushing.

[0029] The working process of the present utility model: During use, the chemical raw materials to be crushed are poured into the conveying box 2 through the first feed hopper 3. The conveying motor 11 drives the conveying shaft 9 to rotate, thereby driving the spiral blades 10 to rotate. Since the spiral blades 10 on both sides have opposite spiral directions, the chemical raw materials in the middle are conveyed to the openings 4 on both sides. During the conveying process, the spiral blades 10 can initially crush the raw materials. Then the materials move to between the two crushing rollers 12 through the flow guiding plates 5. The crushing motor drives the two crushing rollers 12 to rotate towards each other, thereby further pulverizing the raw materials. During the pulverizing process, some raw materials adhere to the crushing rollers 12, and the cleaning brushes 14 on the inclined baffle 13 can clean them, causing them to fall onto the filter plate 6 together with the crushed materials. The raw materials meeting the composite size requirements pass through the filter plate 6 and are collected using the second discharge port 8. The raw materials not meeting the size requirements fall onto the filter plate 6. The striking motor drives the rotating shaft 19 to rotate, thereby driving the two mounting seats 21 to rotate, causing the two striking blocks 23 to continuously strike the filter plate 6, enabling the filter plate 6 to fully filter the raw materials. At the same time, the raw materials not meeting the size requirements move towards the first discharge port 7 for easy collection. Then the collected raw materials are poured into the second feed hopper 25 and crushed together with the next batch of raw materials, ensuring the crushing effect.
