Description

Technical Field

[0001] This utility model relates to the field of rice polishing technology, specifically a rice polishing machine. Background Technology

[0002] Polishing is an important process in turning paddy rice into rice. It is used to remove the small amount of bran powder on the surface of the rice grains. Polished rice is more crystal clear, smooth, and bright in color, with excellent visual appeal, improved storage properties, and higher appearance and commercial value.

[0003] When polishing rice, the polishing machine grinds the rice by using polishing rollers mounted on a hollow main shaft. This causes continuous friction between the rice grains and between the rice grains and the polishing rollers, resulting in the rice surface being ground and polished.

[0004] Existing rice polishing devices have the following drawbacks: they are single-function devices that can only polish rice, and the polishing area is prone to clogging, which leads to a serious problem of broken rice. This is not conducive to the batch polishing of rice and greatly increases the defect rate. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a rice polishing machine with a stirring and polishing mechanism. This addresses the shortcomings of existing rice polishing devices, which have limited functionality, only performing polishing, and are prone to clogging, leading to severe rice breakage and hindering batch polishing of rice, resulting in a significantly higher defect rate.

[0006] The technical solution of this utility model is: a rice polishing machine, including a base plate, a processing box is provided on the top of the base plate, a stirring and polishing mechanism is provided inside the processing box, and a circulation mechanism is provided on the outside of the processing box;

[0007] The circulation mechanism includes a second motor, a stirring rod, a movable rod, stirring blades, a rotating seat, a polishing roller, a rotating plate, a vertical plate, and an arc-shaped block.

The top end of the stirring rod is fixedly connected to the rotating seat. The vertical plate is fixedly installed on the top of the rotating seat, and the rotating plate is fixedly installed on one outer wall of the vertical plate. The rotating seat is arranged in the shape of a T-shaped frustum. The two ends of the polishing roller are respectively movably inserted into the interior of the rotating seat, and the arc-shaped block is fixedly installed on the exterior of the polishing roller. The two ends of the movable rod are respectively movably inserted into the interior of the rotating plate, and the stirring blades are fixedly installed on the exterior of the movable rod.

[0008] Furthermore, a support leg is fixedly installed at the bottom of the base plate, and a foot pad is fixedly installed at the bottom end of the support leg.

[0009] Furthermore, a feed hopper is provided at the top of the processing box, and a discharge pipe is provided at the bottom of the processing box.

[0012] Furthermore, both the extraction pipe and the circulation pipe are fixedly installed inside the side wall of the processing box, and the other end of both the extraction pipe and the circulation pipe is connected to the processing box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The rice polishing mechanism, when in use, involves turning on the motor, which causes the stirring rod to rotate, thus rotating the polishing roller under the friction of the rice. This, combined with the arc-shaped block, polishes the rice. Simultaneously, the vertical plate and rotating plate rotate around the vertical center line of the stirring rod, while the stirring blades rotate under the resistance of the rice, further agitating it. This prevents clogging at the polishing point, reduces broken rice, and improves the quality of the polished rice. The use of stirring blades and the rotating plate also ensures more uniform polishing, increases the rice's movement speed, and enhances the friction between the rice grains, thereby increasing polishing efficiency.

The second motor 16 is fixedly installed at the bottom of the base plate 1, and its output end is fixedly connected to the stirring rod 15. The top end of the stirring rod 15 is fixedly connected to the rotating seat 17. The vertical plate 20 is fixedly installed at the top of the rotating seat 17, and the rotating plate 19 is fixedly installed on one side of the outer wall of the vertical plate 20. The rotating seat 17 is arranged in the shape of a T-shaped frustum. The two ends of the polishing roller 18 are respectively movably inserted into the interior of the rotating seat 17, and the arc-shaped block 22 is fixedly installed on the exterior of the polishing roller 18. The two ends of the movable rod 12 are respectively movably inserted into the interior of the rotating plate 19, and the stirring blade 14 is fixedly installed on the exterior of the movable rod 12. A limit frame 10 is fixedly installed on the inner wall of the processing box 5. The rotating seat 17 is movably connected to the limiting frame 10. A stirring and polishing mechanism is provided.
