Description

Technical Field

[0001] The utility model relates to the technical field of rice-rough separation, in particular to a feeder for a gravity rice-rough separator which is easy to clean. Background Art

[0002] Rice-brown separation is a key step in rice processing equipment, and the screening method is mainly used. Among them, the flat rotary screen is widely used due to its advantages such as short screening route, high screen surface utilization rate and convenient operation. Brown rice is sent to the rice mill for whitening, and the unhusked rice is husked again. The purpose of rice milling is to remove the cortex on the surface of brown rice. Experts have conducted in-depth research on small iron roller separation rice mills to explore potential risks and ensure rice quality and safety. When separating the rice from the brown, the rice needs to be fed into the screening device through a feeder.

[0003] For example, a feeder for rice processing with application number 202211015356.3 places rice from the feed port into the feed box. As the rice falls and is blown by the wind from the bellows, the contact area between the constant temperature plate and the rice is increased when the rice passes through the constant temperature plate, which is convenient for preheating and rubbing the rice skin. Electric heating can improve the preheating effect of the device and increase the temperature of the rice skin. The arc-shaped bumps and inclined structure on the surface of the friction plate are used to allow the rice to roll along the surface of the friction plate, thereby loosening the rice skin and further improving the rice threshing effect in the later stage. However, the device still has certain defects;

[0004] The feeder has many internal structures and multiple protrusions, which causes impurities such as rice husks or dust to be mixed in the internal gaps of the feeder. The feeder needs to be disassembled to clean the inside, which increases the difficulty of cleaning the feeder. Utility Model Content

The servo motor 11 drives the conveying auger 10 through the output shaft. The conveying auger 10 conveys the rice and paddy in the feeding frame 8 to the left to prevent the rice and paddy from forming lumps until the rice and paddy are conveyed above the conveyor belt mechanism 5. At the same time, the servo motor 11 is located on the feeding frame 8. When the servo motor 11 works, the vibration can drive the feeding frame 8 to vibrate, resulting in the adhesion of rice and paddy inside the feeding frame 8.

[0036] When the conveyor belt mechanism 5 conveys the rice and paddy, when the belt in the conveyor belt mechanism 5 passes through the position of the cleaning block 13, the cleaning block 13 can scrape off most of the impurities in the belt and fall onto the lower receiving plate 14. Push the connecting rod 21 back and forth. The connecting rod 21 drives the rack 20 to move left and right. The rack 20 drives the gear 19 to rotate. The gear 19 drives the rotating shaft mechanism 17 to rotate. Then the rotating shaft mechanism 17 drives the brush 18 to rotate. The belt on the conveyor belt mechanism 5 is cleaned twice by the brush 18, thereby improving the cleaning efficiency. When it is necessary to clean the receiving plate 14, directly pull out the baffle 15 outward to make the baffle 15 and the magnetic attraction block 16 away from the feeding frame 3, and then pull out the receiving plate 14.
