Description

Technical Field

[0001] The utility model relates to the field of feeding devices, in particular to a feeding device for rice processing. Background Art

[0002] Rice refers to the grain without removing the husk. Botanically, it belongs to the subspecies of Oryza sativa in the subgenus of Oryza genus in the family Poaceae. When husking the rice, a feeding device is needed to transport the rice to the inside of the husking device. At present, the commonly used feeding devices are mostly spiral feeders.

[0003] At present, a Chinese utility model with the announcement number CN210417144U discloses a spiral feeder. The spiral feeder includes a feeding frame and a feeding hopper arranged on the feeding frame, and also includes a feeding pipe. A feeding screw is arranged in the feeding pipe. The outer diameter of the feeding screw matches the inner diameter of the feeding pipe. The feeding screw is connected to a three-phase asynchronous motor drive. The feeding pipe includes a feeding pipe inlet and a feeding pipe outlet. The feeding pipe inlet is connected to the feeding hopper. The utility model spiral feeder transports paste and powder materials through a screw. The screw and the feeding pipe form a sealed cavity. The metering of the transported material can be achieved by calculating the motor drive amount. At the same time, the device has a low structural cost and is easy to promote. By adjusting the angle of the feeding pipe and the supporting position of the feeding pipe bracket, the connection height and angle of the feeding pipe can be adjusted.

[0004] To sum up, although the feeding device can adjust the connection height and angle of the feeding pipe, there are still certain problems in its use. For example, the sleeve outside the auger of the feeding device is an integrated structure. When the conveyor has been working for a long time, a certain amount of dust and impurities will adhere to the inside of the sleeve. If it is not cleaned, it is easy to cause accelerated wear between the auger and the sleeve. It is inconvenient to clean and maintain the inside of the conveyor sleeve. At the same time, when the conveyor is transporting rice, it is unable to absorb the fine ash inside the rice. When the rice is transported to the shelling equipment, the fine ash will enter the shelling equipment together with the rice, resulting in dust in the rice grains. Utility Model Content
