[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 for Figure 1 The left view. Detailed Implementation

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] Figure 1 , 2 The components include a feed frame 1, a roller assembly 2, a roller 2-1, a toothed column 2-2, a spring 2-3, a telescopic brush 2-4, and a screen 3.

[0017] like Figure 1 , 2 As shown, this utility model is a self-cleaning discharge roller structure, including a feeding frame 1. The feeding frame 1 has two interconnected material bins. Each material bin is rotatably equipped with a material roller assembly 2. The two material roller assemblies 2 cooperate with each other to crush the material.

[0018] A screen 3 is tensioned at the bottom discharge end of the feed frame 1. The crushed material flows out from the mesh of the screen 3 for feeding.

[0019] Each of the roller assemblies 2 includes a roller 2-1, with toothed posts 2-2 evenly distributed on the surface of the roller 2-1. When the roller assembly 2 rotates, the roller 2-1 can clean the mesh of the screen 3.

[0020] The toothed column 2-2 includes a fixed toothed column and a telescopic toothed column. A telescopic brush 2-4 is installed inside the inner cavity of the telescopic toothed column. The inner end of the telescopic brush 2-4 is connected to the top wall of the inner cavity of the telescopic toothed column via a spring 2-3. During operation, one of the material roller assemblies 2 is driven by an external drive component, while the other material roller assembly meshes with the gear of the driving material roller assembly via a gear, thereby achieving synchronous rotation of the two material roller assemblies 2 to realize the granulation operation. When the telescopic toothed column on the material roller 2-1 rotates to the screen position, the spring 2-3 pushes out the telescopic brush 2-4, thus cleaning the clogged mesh openings and ensuring that the granulated particles can pass smoothly through the mesh openings of the screen 3. Under normal conditions, spring 2-3 pushes the telescopic brush 2-4 out. During the rotation of the material roller 2-1, when the telescopic brush 2-4 comes into contact with the inner wall of the feed frame 1, the telescopic brush 2-4 compresses the spring 2-3, and at this time the telescopic brush 2-4 retracts. When the material roller 2-1 drives the corresponding telescopic brush 2-4 to rotate to the mesh of the screen 3, the spring 2-3 pushes the telescopic brush 2-4 out, thereby clearing the blocked mesh and ensuring that the granules formed by granulation can be fed smoothly.

[0021] The inner cavity of the telescopic toothed column is the same length as that of the fixed toothed column, ensuring that during granulation, the telescopic toothed column, when compressed, cooperates with the fixed toothed column to achieve reliable and stable granulation. The fixed toothed column is a solid structure, while the telescopic toothed column has an inner cavity to accommodate the spring 2-3 and the telescopic brush 2-4. The inner end of the spring 2-3 is fixedly connected to the top of the inner cavity of the telescopic toothed column, and the other end of the spring 2-3 is connected to the telescopic brush 2-4.

[0022] The telescopic toothed columns are arranged from one end to the other along the length of the material roller 2-1, and in the circumferential direction, the telescopic toothed columns are arranged sequentially along the circumference until they reach the middle position along the length of the material roller 2-1. At the other end of the material roller 2-1, the arrangement direction of the telescopic toothed columns is symmetrical about the middle position to the aforementioned telescopic toothed columns on the surface of the material roller 2-1. This ensures that all the mesh openings of the screen 3 can be cleaned.

[0023] The bottom of each of the aforementioned silos is constructed in an arc shape, and the inner sides of two silos intersect to form a complete silo.

[0024] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
