[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] The present application provides a technical solution: in order to solve the existing problems raised in the background art.

[0024] In conjunction with the drawings Figures 2-5It can be known that the machine frame 1 is provided with the motor 2 fixed on the upper side of the machine frame 1, the transmission shaft 3 fixed vertically on the inner side of the machine frame 1, a plurality of pairs of support rods 4 fixed horizontally on the inner side of the machine frame 1, and the screen plate structure 5 arranged between each pair of support rods 4. The screen plate structure 5 has two, the screen plate structure 5 on the upper side has a smaller area than the screen plate structure 5 on the lower side, and the mesh number of the screen plate structure 5 on the lower side is greater than the mesh number of the screen plate structure 5 on the upper side. The screen plate structure 5 on the lowermost side does not perform screening and is used for transporting materials of the finest mesh number. The two screen plate structures 5 on the upper side are used for screening the ground materials. One end of the screen plate structure 5 is slidably arranged on the outer side of one support rod 4, and the other end of the screen plate structure 5 is overlapped on the other support rod 4. The compression springs 6 are arranged between the outer sides of the screen plate structure 5 and the inner side of the machine frame 1. The protrusions 5.1 are fixed on one side of the screen plate structure 5. The cams 7 are fixed on the side of the transmission shaft 3 at the protrusions 5.1. The cams 7 are in abutment with the outer sides of the protrusions 5.1, so that the screen plate structure 5 is driven to swing by the cams 7, and the screening is facilitated.

[0025] It can be known from the combination of the drawings 1-3 that the support rods 4 outside the overlapped screen plate structure 5 are hingedly connected with the conveying plates 8. The stop blocks 8.1 are fixed on the sides of the conveying plates 8 close to the sides of the machine frame 1, so that the conveying plates 8 are prevented from being excessively turned over and play a blocking role. The machine frame 1 is provided with the feeding port 9 on the top. The three grinding rollers 10 are rotatably arranged on the side of the feeding port 9 and are used for grinding raw materials. The gears 11 are fixed on one end of the grinding rollers 10 outside the feeding port 9 and are used for relatively rotating the three grinding rollers 10. The motor 12 is fixed on the other side of the feeding port 9 and is fixed on one side of the grinding roller 10 on the side. The machine frame 1 is provided with the multi-layer conveying mechanism 13 on one side. One end of the conveying plate 8 is overlapped on the upper side of the multi-layer conveying mechanism 13, so that the screened materials can be timely conveyed out. The motor 2 and the motor 12 are electrically connected with the external power supply.

[0026] The working principle of the application is as follows. When the materials are screened, the raw materials are first poured into the feeding port 9. The grinding rollers 10 are driven to rotate by the motor 12, so that the raw materials are ground. The ground raw materials fall on the screen plate structure 5. The motor 2 is started to drive the transmission shaft 3 to rotate, so that the cam 7 is driven to rotate. The cam 7 is always in contact with the protrusion 5.1 under the rebound of the compression spring 6, so that the screen plate structure 5 is driven to swing, the screening of the raw materials is realized, the screened materials are conveyed to the upper side of the multi-layer conveying mechanism 13 by the conveying plate 8, and the real-time screening and conveying of raw materials of different sizes are realized.

[0027] The above has described the utility model and its implementation mode, which is not restrictive, and the drawings only show one of the implementation modes of the utility model, and the actual structure is not limited thereto. In summary, if a person skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are not creatively designed, which should belong to the protection scope of the utility model.
