[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a scraping mechanism for a wheel mill, which is mainly used to solve the problem that a scraper with a fixed angle may not be able to adapt to materials with different humidity and particle sizes, resulting in material accumulation or uneven distribution, and the bottom wall of the wheel mill plate becomes uneven after long-term use, the scraper cannot fit well with the bottom wall of the plate, the scraping is not thorough enough, and the efficiency is reduced, and the following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0023] A scraping mechanism of a wheel mill mainly comprises a mounting rod 1, a connecting rod 2, a scraper 3, a locking member 4 and an elastic member 5. The mounting rod 1 is detachably fixed to a rotating shaft inside a wheel mill plate. The detachable feature of the mounting rod 1 allows for quick replacement or maintenance when necessary. The mounting rod 1 is L-shaped with one end facing downward, and the connecting rod 2 is horizontally arranged and rotatably mounted on the bottom end of the mounting rod 1. Such a design enables the connecting rod 2 to be adjusted as needed during the scraping process. The locking member 4 is connected between the mounting rod 1 and the connecting rod 2 and is used to fix the connecting rod 2. The scraper 3 is movably arranged. Below the connecting rod 2, the bottom side of the scraper 3 is in contact with the bottom wall of the roller mill disc. The elastic member 5 is connected between the top of the scraper 3 and the connecting rod 2 to provide necessary elastic support. The design of the elastic member 5 enables the scraper 3 to adapt to the unevenness of the bottom wall of the roller disc and maintain effective scraping. Since the scraper 3 can fit tightly against the bottom wall of the roller disc, the material can be effectively scraped regardless of whether the roller disc is flat, thereby improving the scraping efficiency. The horizontal setting of the connecting rod 2 and the fixing effect of the locking member 4 ensure the stability of the scraping mechanism during operation and reduce the displacement caused by vibration or impact.

[0024] For details, please refer to Figure 2 and Figure 3The locking member 4 includes a locking plate 1 41 mounted on the top of the connecting rod 2, and a locking plate 2 42 is fixedly sleeved on the mounting rod 1. The locking plate 1 41 and the locking plate 2 42 are key components for achieving fine adjustment of the angle and position of the scraper 3. The locking plate 1 41 and the locking plate 2 42 are penetrated with a plurality of locking holes 43 distributed in a rotating array. The plurality of locking holes 43 on the locking plate 1 41 correspond to the plurality of locking holes 43 on the locking plate 2 42 one by one, so that the precise fit between the connecting rod 2 and the connecting rod 2 can be ensured, wherein two corresponding locking holes 43 are movably inserted with an integrated threaded rod 44, one end of the threaded rod 44 is fixed with a fastening block 45, and a nut 46 is threadedly sleeved on the threaded rod 44. By rotating the connecting rod 2, the connecting rod 2 Drive the locking plate 41 to rotate, adjust the angle of the scraper 3, then move the threaded rod 44 through the corresponding two locking holes 43 and fix it through the nut 46 to adapt to materials with different humidity and particle sizes and improve the scraping efficiency. The cooperation of the threaded rod 44 and the nut 46 can quickly fix the scraper 3 at the required angle, thereby improving the adjustment efficiency and operation convenience of the equipment. The design of the locking holes 43 and the threaded rod 44 on the locking plate 1 41 and the locking plate 2 42 provides a stable fixing method to ensure that the scraper 3 will not shift due to vibration during operation. Since the locking member 4 is simply designed and easy to operate, when maintenance or replacement of the scraper 3 is required, the operator can quickly complete the related work and reduce the downtime of the equipment.

[0025] For further information, see Figure 3 A sleeve 21 is fixed to the middle part of the top side of the connecting rod 2, and a locking plate 41 is fixedly sleeved on the top of the sleeve 21. The bottom end of the mounting rod 1 is movably inserted in the sleeve 21 and the locking plate 42 is in contact with the locking plate 41. Through the movable connection between the sleeve 21 and the mounting rod 1, a stable connection between the connecting rod 2 and the mounting rod 1 is achieved, and the stability and reliability of the entire scraper mechanism are improved. The bottom end of the mounting rod 1 can be movably inserted in the sleeve 21, providing a certain degree of position adjustment space. In this way, even if the bottom wall of the grinding disc is worn or uneven, the position of the mounting rod 1 can be adjusted to maintain good contact between the scraper 3 and the grinding disc.

[0026] For further information, see Figure 2 and Figure 4The elastic member 5 includes a spring 51 connected between the scraper 3 and the connecting rod 2. The number of the springs 51 is multiple and evenly distributed to ensure that the scraper 3 can obtain balanced elastic support during the working process. The even distribution of the springs 51 enables the scraper 3 to better adapt to the different shapes and unevenness of the bottom wall of the mill plate, improves the uniformity and efficiency of the scraping material, and the elastic support provided by the spring 51 can reduce the direct friction between the scraper 3 and the mill plate, thereby extending the service life of the scraper 3 and reducing the wear and noise caused by friction; the top of the scraper 3 is fixed with a guide rod 52 that movably penetrates the connecting rod 2, and the spring 51 is sleeved on the guide rod 52. The spring 51 is sleeved on the guide rod 52, so that the two ends of the spring 51 are connected to the scraper 3 and the connecting rod 2 respectively. The function of the guide rod 52 is to guide the movement direction of the spring 51 to ensure that the telescopic movement of the spring 51 does not deviate from the predetermined working range. The use of the guide rod 52 ensures the stability of the spring 51 during the working process, prevents the spring 51 from failing due to excessive stretching or compression, and also protects the scraper 3 from being deviated due to external force.

[0027] In this example, see Figure 2 and Figure 4 The scraper 3 is fixed with inclined protective plates 31 on both sides opposite to each other. The inclined protective plates 31 can effectively prevent the material from splashing or scattering to both sides during the scraping process, keep the working area clean, reduce material loss, and prevent the material from splashing onto the spring 51 and affecting the normal use of the elastic member 5.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
