Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: a granular grinding device for alfalfa production and processing, including a grinding cylinder 1, a reduction motor 2, a grinding block 3, a grinding disc 4, a through hole 5, a stable support 6, a screening box 7, a screen 8, a fixed column 9, a convex block 10, a movable frame 11, an electric telescopic rod 12, an auxiliary rod 13, an installation mechanism 14, a support block 15, a connecting bolt 16, a connecting column 17 and a fixed frame 18.

[0031] When using this granular grinding device for alfalfa production and processing, as Figure 1 , Figure 2 and Figure 3 shown, first add the alfalfa granules to be ground into the grinding cylinder 1, then start the reduction motor 2 installed at the upper end of the grinding cylinder 1. The reduction motor 2 drives the grinding block 3 to slowly rotate in the grinding cylinder 1. The alfalfa granules are ground by the grinding block 3 and the grinding disc 4. At the same time, the grinding block 3 drives the stable support 6 to rotate in the grinding cylinder 1, improving the stability of the rotation of the grinding block 3 in the grinding cylinder 1. And a screening box 7 is arranged below the grinding cylinder 1. A screen 8 is installed in the middle card slot of the screening box 7. The powder after grinding falls onto the screen 8 in the middle of the screening box 7 through the through hole 5. The powder can be screened through the screen 8, thereby improving the uniformity of the powder and the processing quality of the product;

[0032] As Figure 1 and Figure 4As shown, during the actual screening process, the electric telescopic rod 12 installed at the lower right end of the grinding cylinder 1 can be activated. The output end of the electric telescopic rod 12 is connected to the fixed column 9 at the upper right end of the screening box 7. The electric telescopic rod 12 pushes the fixed column 9 to move left and right, causing the fixed column 9 to move left and right inside the movable frame 11. At the same time, the fixed column 9 drives the sliding between the convex block 10 and the movable frame 11, improving the stability of the fixed column 9 during movement. The fixed column 9 can drive the screening box 7 and the screen 8 to move left and right at the lower end of the grinding cylinder 1, achieving the effect of rapid screening, thus greatly improving the screening efficiency of the powder;

[0033] In addition, after the screening process is completed, as Figure 1 , Figure 5 and Figure 6 shown, the installation mechanisms 14 are arranged at equal angles on the outside of the screening box 7, and the installation mechanisms 14 are arranged at equal angles on the side of the screening box 7. The installation mechanism 14 includes a support block 15 fixedly connected to the side of the screening box 7, a connecting bolt 16 for adjustment, a connecting column 17 rotatably connected to the lower end of the connecting bolt 16, and a fixed frame 18 for limiting. By rotating the connecting bolt 16 threadedly connected to the middle of the support block 15, the connecting bolt 16 rotates with the connecting column 17, causing the connecting column 17 to move downward. At this time, the connecting column 17 drives the fixed frame 18 to move downward, and the fixed frame 18 disengages from the auxiliary rod 13. Then, by flipping the fixed frame 18, the fixed frame 18 rotates with the connecting column 17, causing the fixed frame 18 to disengage from the auxiliary rod 13, thereby releasing the limitation between the auxiliary rod 13 and the screening box 7. The auxiliary rod 13 is fixedly connected to the side of the screen 8. By pulling the auxiliary rod 13 downward, the auxiliary rod 13 drives the screen 8 to be pulled out from the inside of the screening box 7, facilitating the cleaning of the screened impurities and cleaning the screen 8 at the same time to prevent the screen 8 from being blocked.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
