[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, a rice milling and polishing device for rice processing provided by an embodiment of the present invention includes a shell 1, the interior of the shell 1 is connected to a rice milling roller 2 and a rice milling roller 3 through bearings, a horizontal tube 5 is fixed to the outer wall of one side of the shell 1, the interior of the horizontal tube 5 is connected to a rotating shaft 7 through a bearing, a polishing roller 9 is fixed to the outside of the rotating shaft 7, a motor 10 is fixed to one end of the horizontal tube 5, the output shaft of the motor 10 is connected to the rotating shaft 7 through a key, the outer wall of the horizontal tube 5 is provided with evenly distributed through holes 13, the bottom of the rice milling roller 2 and the rice milling roller 3 is provided with a mesh plate 4, and a transition bucket 6 is fixed to the outer wall of one side of the shell 1, and the bottom of the transition bucket 6 is connected to the horizontal tube 5.

[0023] Specifically, in this embodiment, it includes a shell 1, the interior of which is connected to a rice milling roller 2 and a rice milling roller 2 3 through bearings, and the brown rice is milled by the rice milling roller 2 and the rice milling roller 2 3. A horizontal tube 5 is fixed to the outer wall of one side of the shell 1, and a rotating shaft 7 is connected to the interior of the horizontal tube 5 through a bearing. A polishing roller 9 is fixed to the outside of the rotating shaft 7. When the polishing roller 9 rotates, it polishes the white rice formed after rice milling. A motor 10 is fixed to one end of the horizontal tube 5, and the output shaft of the motor 10 is connected to the rotating shaft 7 through a key. The rotating shaft 7 is driven to rotate by the motor 10. The outer wall of the horizontal tube 5 is provided with evenly distributed through holes 13, and the powder generated when the white rice is polished flows out from the through holes 13. A mesh plate 4 is provided at the bottom of the rice milling roller 2 and the rice milling roller 2 3. The mesh plate 4 filters the white rice. A transition bucket 6 is fixed to the outer wall of one side of the shell 1, and the bottom of the transition bucket 6 is connected to the horizontal tube 5. The white rice falls from the mesh plate 4 to the transition bucket 6, so that the white rice enters the horizontal tube 5 from the transition bucket 6.

[0024] The utility model provides a rice milling and polishing device for rice processing, which can mill brown rice through rice milling rollers 1 2 and 2 3, and polish white rice through polishing roller 9, so that when brown rice is processed, polished rice can be formed through one device, thereby making the processing of brown rice more convenient and improving the processing efficiency of brown rice.

[0025] In another embodiment provided by the present invention, a feed hopper 12 is welded to the top outer wall of the shell 1, and brown rice is added to the shell 1 from the feed hopper 12. A guide plate 21 is provided inside the shell 1, and the guide plate 21 is located on the top of the rice milling roller 2 and the rice milling roller 2 3. The guide plate 21 can accurately flow the brown rice into the space between the rice milling roller 2 and the rice milling roller 2 3; a motor 20 is fixed to the outer wall of one side of the shell 1, and the output shaft of the motor 20 is connected to the rice milling roller 2 by a key. The motor 20 drives the rice milling roller 2 to rotate and the brown rice enters between the rice milling roller 2 and the rice milling roller 2 3. The rice milling roller 2 drives the brown rice to move, and the brown rice drives the rice milling roller 2 3 to move through friction. At this time, a speed difference is formed between the rice milling roller 2 and the rice milling roller 2 3, so that the brown rice entering between the rice milling roller 2 and the rice milling roller 2 3 is subjected to the rice milling operation.

[0026] In another embodiment provided by the present invention, an auger plate 8 is fixed to the outside of the rotating shaft 7, the auger plate 8 is located inside the horizontal tube 5, and the auger plate 8 is located at the bottom of the transition bucket 6. The auger plate 8 is driven to rotate by the rotating shaft 7, so that the auger plate 8 can transport the white rice inside the transition bucket 6 to the polishing roller 9 in time, thereby preventing the white rice from being blocked inside the transition bucket 6, and at the same time ensuring stable feeding during polishing of the white rice.

[0027] In another embodiment provided by the present invention, one side of the mesh plate 4 is hinged to the inner wall of the shell 1, and a spring 17 is fixed between the other side of the mesh plate 4 and the transition bucket 6, and the spring 17 elastically supports the mesh plate 4; a baffle 14 is fixed inside the shell 1, and a driving gear 15 is fixed to the interior of the shell 1 extending from the rotating shaft 7. The outer wall of one side of the baffle 14 is connected to a turntable 18 through a bearing, and a pull rope 19 is hinged between the turntable 18 and the mesh plate 4. The mesh plate 4 is driven to vibrate by the set turntable 18 and the connecting rope, so that the mesh plate 4 can screen the white rice, thereby separating the rice bran from the white rice in time, so that White rice has a better effect when polishing. One end of the connecting shaft of the turntable 18 passes through the baffle 14 and is fixed with a driven gear 16. The driven gear 16 is engaged with the driving gear 15. The diameter of the driven gear 16 is much smaller than the driving gear 15, so that the driving gear 15 can drive the driven gear 16 to rotate at high speed, thereby causing the turntable 18 to rotate at high speed, so that the vibration frequency of the mesh plate 4 is increased; a slag discharge hopper 22 is fixed to the bottom outer wall of the shell 1, and the rice bran flows out of the slag discharge hopper 22 after passing through the mesh plate 4. A discharge pipe 11 is fixed to the bottom outer wall of the horizontal pipe 5 near the motor 10, and the polished rice formed after polishing flows out from the discharge pipe.

[0028] Working principle: When in use, the rice milling roller 1 2 is driven to rotate by the motor 2 20. At this time, the rice milling roller 2 3 is stationary relative to the rice milling roller 1 2, and the motor 10 drives the shaft 7 to rotate. The rotation of the shaft 7 drives the polishing roller 9, the auger plate 8 and the driving gear 15 to rotate. The rotation of the driving gear 15 drives the driven gear 16 and the turntable 18 to rotate. Since the pull rope 19 is hinged to the turntable 18, the turntable 18 rotates and drives the mesh plate 4 to vibrate through the pull rope 19; pour the brown rice into the feed hopper 12, so that the brown rice enters between the rice milling roller 1 2 and the rice milling roller 2 3, and the rice milling roller 2 drives the brown rice to move. The brown rice is driven by friction. The rice milling roller 2 3 moves, and a speed difference is formed between the rice milling roller 1 2 and the rice milling roller 2 3, so that the brown rice entering between the rice milling roller 1 2 and the rice milling roller 2 3 is milled, so that the brown rice is transformed into white rice. After milling, the white rice falls on the mesh plate 4, and the vibration of the mesh plate 4 sieves the white rice, so that the rice bran passes through the mesh plate 4 and flows out from the slag discharge bucket 22, and the white rice rolls into the transition bucket 6 by vibration. As the auger plate 8 rotates, the white rice enters the gap between the polishing roller 9 and the horizontal tube 5, and the polishing roller 9 polishes the white rice when it rotates. The polished rice formed after polishing flows out from the discharge pipe, and the powder generated by polishing flows out from the through hole 13 on the outer wall of the horizontal tube 5.

[0029] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
