These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0025] Reference Figure 1 - Figure 5As shown, the utility model provides a technical solution: a double-shaft crusher, including a body 1, a support frame 2 is fixedly connected to the bottom end of the body 1, a feed port 3 is provided at the top of the body 1, motors 4 are fixedly connected to both sides of the body 1, a crushing roller 5 is installed at the output end of the motor 4, a filter plate 6 is fixedly connected to the inner cavity of the body 1, a pull rod 7 is slidably connected to the inner cavity of the body 1, a scraper 8 is fixedly connected to the other end of the pull rod 7, an open slot 9 is provided inside the body 1, a hollow block 10 is slidably connected to the inner cavity of the open slot 9, and one end of the hollow block 10 close to the scraper 8 is fixedly connected to the scraper 8, a limiting block 11 is fixedly connected to the surface of the body 1, and a particle collecting box 12 is slidably connected to the opposite surface of the limiting block 11. When the staff needs to ensure the uniformity of the crushed particle size, the staff starts the motor 4 to make the motor 4 Drive the crushing roller 5 to rotate. At this time, the staff pours the material from the feed port 3, so that the crushing roller 5 crushes it, and the material falls on the top of the filter plate 6 for filtration. Larger particles will remain on the surface of the filter plate 6. At this time, the staff pulls the pull rod 7, so that the pull rod 7 drives the scraper 8 to move. As the scraper 8 moves, the scraper 8 drives the surface of the hollow block 10 to slide in the inner cavity of the open groove 9. At the same time, the hollow block 10 drives the first spring 14 to stretch and store force. Through repeated pulling and pulling by the staff, the scraper 8 collects the large particles that cannot be filtered out, and the large particles fall into the inner cavity of the particle collection box 12 along the slots on both sides of the body 1. Through the setting of the above structure, the staff ensures the uniformity of the crushed particles, so that the material particles obtained by the crushing are kept the same size, further improving the crushing efficiency.

[0026] Reference Figure 4 As shown, in this embodiment: the inner cavity of the open groove 9 is fixedly connected with a guide rod 13, and the surface of the guide rod 13 is slidably connected to the inner cavity of the hollow block 10. The staff pulls the pull rod 7 to make the pull rod 7 drive the scraper 8 to move, and at the same time makes the inner cavity of the hollow block 10 slide on the surface of the limit block 11. Through the setting of the above structure, the scraper 8 maintains directional displacement when it moves, and will not offset.

[0027] Reference Figure 4 As shown, in this embodiment: the inner cavity of the open groove 9 is fixedly connected with a first spring 14, and the end of the first spring 14 close to the hollow block 10 is fixedly connected to the hollow block 10. The staff pulls the pull rod 7 to make the hollow block 10 drive the first spring 14 to stretch and store force. Through the setting of the first spring 14, the rebound force of the first spring 14 continues to stretch the hollow block 10 to reset it, which is convenient for the staff to operate next time.

[0028] Reference Figure 5As shown, in this embodiment: a limiting groove 15 is opened inside the limiting block 11, and the inner cavity of the limiting groove 15 is slidably connected to a slide rod 16, and the end of the slide rod 16 close to the particle collection box 12 is fixedly connected to the particle collection box 12. The staff pulls the particle collection box 12 to move the particle collection box 12 upward, and at the same time, the particle collection box 12 drives the surface of the slide rod 16 to slide in the inner cavity of the limiting groove 15. Since the limiting groove 15 is opened inside the limiting block 11 and the limiting groove 15 is not opened to the bottom end, through the setting of the above structure, the particle collection box 12 is directionally limited and the particle collection box 12 can also be disassembled.

[0029] Reference Figure 6 and Figure 7 As shown, in this embodiment: the bottom end of the body 1 is fixedly connected with a flow control plate 17, the inner cavity of the flow control plate 17 is slidably connected to the baffle 18, and the surface of the baffle 18 is fixedly connected with a handle 19, the inner cavity of the flow control plate 17 is fixedly connected to a limiting column 20, and the surface of the limiting column 20 is slidably connected with a special-shaped block 21, and the bottom end of the baffle 18 is provided with a special-shaped groove 22. When the staff needs to control the flow and collect the crushed material particles, the staff crushes the material, and the particles fall under the influence of gravity. At this time, the staff pulls the special-shaped block 21, so that the inner cavity of the special-shaped block 21 slides on the surface of the limiting column 20, and at the same time squeezes the second spring 25 to store force. At this time, the staff can pull the handle 19 outward, driving the surface of the baffle 18 to gradually separate from the inner cavity of the flow control plate 17. At this time, the staff can freely adjust the flow rate of the particles in the inner cavity of the flow control plate 17. Through the arrangement of the above structure, the staff can freely control the flow rate of the material particles when collecting the material particles, thereby improving the applicability of the crusher.

[0030] Reference Figure 6 As shown, in this embodiment: a guide groove 23 is opened inside the flow control plate 17, and the inner cavity of the guide groove 23 is slidably connected to a guide block 24, and the end of the guide block 24 close to the baffle 18 is fixedly connected to the baffle 18. The staff pulls the handle 19 so that the handle 19 drives the surface of the baffle 18 to gradually separate from the inner cavity of the flow control plate 17. At the same time, the baffle 18 drives the surface of the guide block 24 to slide in the inner cavity of the guide groove 23. Through the setting of the above structure, the baffle 18 maintains directional displacement during displacement, ensuring the coordination between the structures.

[0031] Reference Figure 7As shown, in this embodiment: the inner cavity of the flow control plate 17 is fixedly connected to the second spring 25, and the top end of the second spring 25 is fixedly connected to the special-shaped block 21. The staff pulls the special-shaped block 21 to make the inner cavity of the special-shaped block 21 slide on the surface of the limiting column 20, and at the same time squeezes the second spring 25 to store force. When the staff needs to freely adjust the flow limit of the baffle 18, the staff releases the pulling force on the special-shaped block 21, so that the second spring 25 releases the stored force to push the special-shaped block 21 to move upward, so that the top end of the special-shaped block 21 is engaged with the inner cavity of the special-shaped groove 22, which is convenient for limiting and fixing the baffle 18.

[0032] Working principle: When the staff needs to ensure the uniformity of the size of the crushed particles, the staff starts the motor 4, so that the motor 4 drives the crushing roller 5 to rotate. At this time, the staff pours the material from the feed port 3, so that the crushing roller 5 crushes it, and the material falls on the top of the filter plate 6 for filtration. The larger particles will remain on the surface of the filter plate 6. At this time, the staff pulls the pull rod 7, so that the pull rod 7 drives the scraper 8 to move. With the displacement of the scraper 8, the scraper 8 drives the surface of the hollow block 10 to slide in the inner cavity of the open groove 9. At the same time, the hollow block 10 drives the first spring 14 to stretch and store force. Through repeated pulling and pulling by the staff, the scraper 8 collects the large particles that cannot be filtered out, and the large particles fall into the inner cavity of the particle collection box 12 along the notches on both sides of the body 1. Through the setting of the above structure, The staff ensures the uniformity of the crushed particles, so that the material particles obtained by crushing are kept of the same size, further improving the crushing efficiency. When the staff needs to control the flow and collect the crushed material particles, the staff crushes the material, and the particles fall under the influence of gravity. At this time, the staff pulls the special-shaped block 21 to make the inner cavity of the special-shaped block 21 slide on the surface of the limit column 20, and at the same time squeezes the second spring 25 to store force. At this time, the staff can pull the handle 19 outward to drive the surface of the baffle 18 to gradually separate from the inner cavity of the flow control plate 17. At this time, the staff can freely adjust the flow rate of the particles in the inner cavity of the flow control plate 17. Through the setting of the above structure, the staff can freely control the flow rate of the material particles when collecting material particles, thereby improving the applicability of the crusher.
