[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-6 As shown, this utility model provides a feeding mechanism for a rice processing and filling machine, including a tank body 1. A feeding pipe 11 is installed at the bottom of the tank body 1, and the tank body 1 is connected to the filling machine equipment 4 through the feeding pipe 11. A fixing plate 2 is fixedly provided at the top of the external tank body 1 through the feeding pipe 11. The fixing plate 2 is used for fixed support. A threaded sleeve 21 is rotatably provided at the bottom of the fixing plate 2. The rotation of the threaded sleeve 21 drives the rotation of the threaded rod 22. The threaded rod 22 is threadedly inserted into the threaded sleeve 21 and is inserted through the fixing plate 2. A connecting plate 23 is rotatably provided at the bottom of the threaded rod 22, and a guide rod 2 is fixedly provided at the bottom of the connecting plate 23. 4. The guide rod 24 is used to drive the conical head 25 to move up and down. The conical head 25 is fixedly provided at the bottom end of the guide rod 24. The up and down movement of the conical head 25 can drive it to move within the feeding pipe 11, thereby controlling the feeding space of the feeding pipe 11 and thus controlling the feeding rate of rice. The conical head 25 is movably inserted into the feeding pipe 11. A rotating rod 26 is rotatably inserted into the connecting plate 23. A first gear 27 is fixedly provided on the outside of the rotating rod 26, and a second gear 28 is fixedly provided on the outside of the threaded sleeve rod 21. The first gear 27 and the second gear 28 mesh with each other, so that the rotating rod 26 rotates and drives the threaded sleeve rod 21 to rotate.

[0022] The inner wall of the tank body 1 is provided with an internal gear ring 3, and the bottom end of the internal gear ring 3 is fixed with symmetrically distributed actuating rods 33. The two actuating rods 33 are in contact with the inner wall of the tank body 1. A rotating shaft 31 is rotatably inserted into the fixed plate 2. A No. 3 gear 32 is fixed on the outside of the rotating shaft 31. The No. 3 gear 32 meshes with the internal gear ring 3.

[0023] By adopting the above technical solution, the rotation of gear 32 drives the internal gear ring 3 and the actuating rod 33 to rotate, thereby agitating the rice on the circumference of the tank body and avoiding the problem of blockage during material feeding.

[0024] The inner side of the tank body 1 is fixed with symmetrically distributed feed pipes 12, and a feed box 13 is installed at the top of the feed pipes 12.

[0025] By adopting the above technical solution, the feed pipe 12 and the feed box 13 can easily guide the rice into the tank 1.

[0026] An auxiliary rod 14 is fixedly provided at the top of the connecting plate 23, and the auxiliary rod 14 is movably inserted into the fixed plate 2.

[0027] By adopting the above technical solution, the auxiliary rod 14 can limit the connection plate 23 and the threaded rod 22, so that they can move up and down stably.

[0028] A reinforcing rod 15 is fixedly provided between the guide rod 24 and the connecting plate 23.

[0029] By adopting the above technical solution, the reinforcing rod 15 can improve the stability of the guide rod 24.

[0030] A motor 29 is installed at the top of the fixed plate 2. The output shaft of the motor 29 is inserted through the fixed plate 2 and fixedly connected to the rotating rod 26.

[0031] By adopting the above technical solution, the end of the output shaft of motor 29 rotates, driving the rotating rod 26 to rotate, thereby providing power output.

[0032] The inner wall of the tank body 1 is provided with a protective ring 34, which is located above the internal toothed ring 3.

[0033] By adopting the above technical solution, the protective ring 34 can protect the internal toothed ring 3 and prevent impurities from adhering to its outer side.

[0034] The top of the fixed plate 2 is fixedly equipped with a second motor 35, and the end of the output shaft of the second motor 35 is inserted through the fixed plate 2 and fixedly connected to the rotating shaft 31.

[0035] By adopting the above technical solution, the output shaft end of the No. 2 motor 35 rotates, driving the rotating shaft 31 to rotate, thereby providing power output.

[0036] Working principle: First, the rice to be filled enters the tank 1 through the feeding box 13 and the feeding pipe 12. At this time, the rice to be filled accumulates in the tank 1. It is then transferred to the filling machine 4 through the discharge pipe 11. The filling machine 4 fills the rice. During the filling process, the second motor 35 is started, and the output shaft of the second motor 35 rotates, which drives the rotating shaft 31 to rotate. The rotating shaft 31 rotates, which drives the third gear 32 to rotate. The rotating gear 32 rotates, which drives the meshing internal gear ring 3 to rotate. The rotating internal gear ring 3 rotates, which drives the two actuating rods 33 to rotate. The actuating rods 33 can move the rice on the inner wall of the tank 1, avoiding rice accumulation and blockage.

[0037] When the feeding rate of rice needs to be adjusted, motor 29 is started. Motor 29's output shaft rotates, causing rotating rod 26 to rotate. Rotating rod 26 rotates, causing gear 27 to rotate. Gear 27 rotates, causing meshing gear 28 to rotate. Gear 28 rotates, causing threaded sleeve 21 to rotate outside fixed plate 2. This rotation of threaded sleeve 21 causes threaded rod 22 to rotate. While rotating, threaded rod 22 is limited by connecting plate 23 and auxiliary rod 14, allowing it to move up and down. This, in turn, causes connecting plate 23 to move up and down. The downward movement of connecting plate 23 causes guide rod 24 to move down, which in turn causes conical head 25 to move down. As conical head 25 moves down, a gap exists between it and feeding pipe 11. By controlling the space between conical head 25 and feeding pipe 11, the feeding rate of rice can be controlled, thus ensuring the stability and accuracy of the filling process.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
