[0004] The above-mentioned device places the raw materials to be crushed into the crushing tank, and then starts the first drive motor. The first drive motor drives the drive gear to rotate through the drive shaft. The rotation of the drive shaft can cause the connecting shaft and the crushing roller to rotate, so that the crushing roller can easily crush the raw materials. The filter holes inside the discharge port can filter the crushed raw materials. It solves the problem that it is inconvenient to rotate two sets of crushing rollers at the same time, which easily increases costs and results in poor crushing effect. However, the lack of cleaning of the crushing rollers during use causes raw materials to adhere to the crushing rollers, which leads to poor contact between the crushing rollers and affects the subsequent crushing effect. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Combination Figures 1-5 A crusher for crushing raw materials includes a crushing box 1, a guide plate 2 symmetrically fixedly connected to the top of the inner wall of the crushing box 1, a guide block 3 symmetrically fixedly connected to the bottom of the inner wall of the crushing box 1, and a crushing mechanism 4, a scraping mechanism 5 and a striking mechanism 6 provided on the crushing box 1.

[0026] See Figure 4 Furthermore, the crushing mechanism 4 includes drive shafts 401 symmetrically rotatably connected to the inner wall of the crushing box 1. Crushing rollers 402 are fixedly connected to the outer walls of both drive shafts 401. The crushing mechanism 4 also includes U-shaped plates 403 fixedly connected to the crushing box 1. Both U-shaped plates 403 are rotatably connected to the drive shafts 401. A motor 404 is fixedly connected to the end of the U-shaped plate 403 away from the crushing box 1. The driving end of the motor 404 is rotatably connected to one of the drive shafts 401. Gears 405 are fixedly connected to the outer walls of both drive shafts 401. The two gears 405 are meshed together.

[0027] Specifically, the motor 404 drives one of the drive shafts 401 to rotate, and the gear 405 makes the two drive shafts 401 rotate in opposite directions, so that the crushing roller 402 can rotate in opposite directions, thus crushing the raw materials.

[0028] Example 2

[0029] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the scraping mechanism 5 includes an electric push rod 501 fixedly passing through both ends of the crushing box 1. The telescopic ends of the two electric push rods 501 are fixedly connected to scrapers 502. Slide grooves 503 are symmetrically opened on both sides of the inner wall of the crushing box 1. The two scrapers 502 are both set in the slide grooves 503. The two scrapers 502 are in contact with the outer wall of the crushing roller 402. Discharge ports 504 are provided at the positions of the guide blocks 3 in the crushing box 1.

[0030] Specifically, the electric push rod 501 moves the scraper 502, which makes the scraper 502 and the outer wall of the crushing roller 402 in close contact. This removes the raw material adhering to the crushing roller 402 and keeps the crushing rollers 402 in close contact, thus preventing any impact on the crushing effect. The scraped-off raw material is discharged through the guide block 3 and the discharge port 504 and is collected and processed for recycling.

[0031] Example 3

[0032] See Figure 3 and Figure 5 Furthermore, based on Embodiment 1 and Embodiment 2, the striking mechanism 6 includes a drive shaft 601 symmetrically rotatably connected to the inner wall of the crushing box 1. The ends of the two drive shafts 601 away from the crushing box 1 are each fixedly connected to a first pulley 602. The striking mechanism 6 also includes a second pulley 603 fixedly connected between the gear 405 on the outer wall of the drive shaft 401 and the crushing box 1. The two sets of second pulleys 603 and the first pulleys 602 are connected by a belt. The outer walls of the two drive shafts 601 are each fixedly connected to a plurality of uniformly arranged elastic columns 604. The ends of the plurality of elastic columns 604 away from each other are each fixedly connected to a striking ball 605 for striking the guide plate 2.

[0033] Specifically, the drive shaft 401 drives the second pulley 603 to rotate, which in turn drives the first pulley 602 to rotate via a belt. This drives the transmission shaft 601 to rotate, which in turn drives the elastic column 604 to rotate. As a result, the striking ball 605 strikes the guide plate 2, completely clearing the raw material from the guide plate 2 and preventing the accumulation of raw material from affecting the feeding process.

[0034] In actual operation, the raw material is poured onto the guide plate 2, and then the motor 404 is started to drive one of the drive shafts 401 to rotate. Through the action of the gear 405, the two drive shafts 401 can rotate in opposite directions, and the crushing roller 402 can rotate in opposite directions, so that the raw material can be crushed.

[0035] During the crushing process, the electric push rod 501 can be activated to push the scraper 502 to move and make it in close contact with the crushing roller 402, thereby cleaning off the raw material adhering to the crushing roller 402. This ensures that the crushing rollers 402 are always in close contact, which improves the crushing effect of the raw material. Even if the scraper 502 wears down, the contact effect between it and the crushing roller 402 can still be maintained, ensuring long-term use.

[0036] Furthermore, during the crushing process, the drive shaft 401 rotates the second pulley 603, and through the belt, it rotates the first pulley 602. Thus, it can rotate the transmission shaft 601, and through the elastic column 604 and the striking ball 605, it can strike the guide plate 2 to make it vibrate, thereby preventing the accumulation of raw materials on the guide plate 2 and ensuring the smoothness of the feed.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
