Description

Technical Field

[0001] The utility model relates to the technical field of rice polishing equipment, in particular to a feeding device of a rice polishing machine. Background Art

[0002] The rice polisher processes the surface of rice through a high-speed rotating polishing cylinder and an internal mechanical structure to remove the adhering bran powder and other impurities, making the rice surface smooth;

[0003] When the rice polisher is polishing the rice, the rice is continuously conveyed into the feeding hopper on the rice polisher through an external conveying mechanism, and then the rice is conveyed into the large polisher through the feeding hopper provided with a slidable baffle or a sub-screen to control the feeding flow and quality of the rice. For example, a feeding device for a rice polisher disclosed in announcement No. CN213726663U solves the problem that the feeding amount cannot be controlled due to manual feeding during the rice polishing process. The feeding device is proposed, and the slidable baffle can be set to quantify the amount of rice fed into the polisher each time, and the feeding amount can be accurately controlled, thereby ensuring the large The polishing quality of rice, and due to the setting of multiple layers of baffles, the quantitative volume can also be adaptively adjusted according to the power and capacity of the equipment. During use, the application still needs to manually add rice to the feeding device. Even if a single feeding amount is achieved through multiple layers of baffles, the existing rice polishing machines are mostly mechanical structures that operate continuously. Therefore, the overall feeding process is inefficient, and when the rice is fed into the rice polishing machine by pulling the baffle, if the polishing flow rate is small and the feeding distance between the baffle and the feeding barrel is narrow, it is easy for the rice to accumulate in the feeding barrel and rub and squeeze each other, thereby causing blockage.

[0023] As Figures 2 - 4 、 Figure 6As shown, a plurality of slots 10 are formed inside the fairing 5. The fairing 5 is inserted and installed on a plurality of inclined support plates 4 through the slots 10. With the arrangement of the fairing 5, it can provide an installation condition for the adjusting screw 15. At the same time, it can protect the motor 7 from the direct impact of rice. An installation hole 11 is formed at the top of the fairing 5. An installation seat 12 is inserted into the installation hole 11. A rotating groove 14 is formed inside the installation seat 12. Through holes are formed at the bottom and the bottom of the rotating groove 14. A skirt 13 is fixedly installed outside the installation seat 12. The skirt 13 is placed at the inner top of the fairing 5 and fixed by screws. With the arrangement of the installation seat 12, the top of the adjusting screw 15 can rotate inside the rotating groove 14. A rotating block 16 is fixedly installed at the top of the adjusting screw 15. A hexagonal block 17 is fixedly installed at the top of the rotating block 16. The rotating block 16 is rotatably installed inside the rotating groove 14, and the hexagonal block 17 is inserted into the through hole at the inner top of the rotating groove 14;

[0024] As Figure 2 , Figure 5 shown, a first bottom plate 18 is fixedly installed at the bottom of the lifting rod 6. A limiting ring 19 is fixedly installed at the upper position outside the lifting rod 6. A threaded groove 20 is formed at the top of the lifting rod 6. The lifting rod 6 is inserted into the sleeve 9. The threaded groove 20 is threadedly connected with the adjusting screw 15.
