It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a raw material pretreatment device for preparing nifuratel tablets, comprising a stirring device body 3, a pretreatment device body 1 is provided on the side of the stirring device body 3, a second motor 18 and a mounting plate 13 are provided on the pretreatment device body 1, the mounting plate 13 is provided in the pretreatment device body 1, a limiting groove 14 is provided on the mounting plate 13, a limiting plate 15 is provided in the limiting groove 14, a sieve plate 16 is provided on the side of the limiting plate 15, and the side of the sieve plate 16 is in contact with the wear-resistant plate 9 provided on the side of the repair plate 7;

[0023] During specific use, the staff places the raw materials into the main body 1 of the pretreatment equipment, crushes the raw materials through the crushing roller 8, then pulls out the storage basket 6, and places the crushed raw materials on the stirring device main body 3 for stirring. Example 2

[0024] On the basis of Example 1, in order to facilitate the later maintenance of the staff, a second motor 18 is provided. The second motor 18 is fixedly connected to the pretreatment equipment body 1. The transmission shaft of the second motor 18 is fixedly connected to the striking block 17. When the second motor 18 is started, the striking block 17 is driven to rotate. The striking block 17 rotates, and one end of the striking block 17 strikes the mounting plate 13. The mounting plate 13 is fixedly connected to the limiting rod 12. One end of the limiting rod 12 is stuck in the limiting hole 11 opened on the pretreatment equipment body 1. The limiting hole 11 is circular. The groove-shaped structure causes the limiting rod 12 fixedly connected to the mounting plate 13 to move upward along the limiting hole 11 opened on the main body 1 of the pretreatment equipment, so that the mounting plate 13 moves upward, the spring 10 is compressed, and the striking block 17 continues to rotate. When the striking block 17 is separated from the mounting plate 13, the spring 10 pushes the mounting plate 13 and the limiting rod 12 to move downward along the limiting hole 11. Under the action of the spring 10, the mounting plate 13 vibrates up and down, shaking off the crushed raw materials on the screen plate 16, thereby improving the use effect of the device;

[0025] The staff can then pull the sieve plate 16 so that the sieve plate 16 and the limiting plate 15 can slide out along the limiting groove 14 opened on the mounting plate 13, and the staff can then take out the sieve plate 16, which has a simple structure and is convenient for the staff to carry out the later maintenance of the device, and convenient for the staff to use, thereby improving the reliability of the device. Example 3

[0026] On the basis of the second embodiment, the use effect of the device is improved, and a stirring device body 3 is provided. The stirring device body 3 is fixedly connected to the pretreatment equipment body 1. The pretreatment equipment body 1 is provided with a lower mounting port 5, and a storage basket 6 is clamped on the lower mounting port 5. The storage basket 6 can be slid along the lower mounting port 5 into the pretreatment equipment body 1. The staff places the raw materials into the pretreatment equipment body 1 and then closes the box door on the pretreatment equipment body 1. A spring 10 is fixedly connected to the mounting plate 13, and the other end of the spring 10 is fixedly connected to the pretreatment equipment body 1. A first motor 2 is fixedly connected to the pretreatment equipment body 1, and a drive shaft of the first motor 2 is connected to the powder The crushing roller 8 is fixedly connected and rotatably connected to the main body 1 of the pretreatment equipment through a rotating shaft. The first motor 2 is started to drive the crushing roller 8 to rotate, and the raw materials are crushed by the crushing roller 8. The crushed raw materials fall into the storage basket 6. The staff then pulls the storage basket 6 to extract it. The staff pours the raw materials in the storage basket 6 into the stirring device main body 3, and the crushed raw materials are stirred by the stirring device main body 3. The device has a compact structure, which is convenient for the staff to actually carry out production work, reduces the equipment footprint, is convenient for use in laboratories or small-scale production lines, is easy to move and reconfigure the production line, quickly adapts to product changes, and has high practicality.

[0027] Working principle: During actual use, the raw materials are crushed by the crushing roller 8 in the main body 1 of the pretreatment equipment, so that the crushed raw materials fall into the storage basket 6. The staff pours the raw materials in the storage basket 6 into the stirring device main body 3 for stirring. In this process, the crushed raw materials need to be screened by the sieve plate 16 in the main body 1 of the pretreatment equipment. The sieve plate 16 needs to be cleaned after long-term use. Tighten and remove the bolts on the inspection plate 7, remove the inspection plate 7 from the main body 1 of the pretreatment equipment, and make the sieve plate 16 and the limit plate 15 slide out along the limit groove 14. The staff can then clean the sieve plate 16 and the blockage in the sieve holes on the sieve plate 16. The device has a compact structure that is convenient for actual use by personnel, a simple structure and easy operation, which is convenient for personnel to clean the device in the later stage and improves the reliability of the device.
