Description

Technical Field

[0001] The utility model relates to the technical field of crop processing, and particularly relates to a rice grain stripping device. Background Art

[0002] As one of the important food crops in the world, the mechanization level of rice harvesting and post-harvest processing directly affects agricultural production efficiency and economic benefits. The rice grain stripping device is a key equipment for separating paddy from rice straw. Especially in small farms and family farms, the application of such devices can significantly improve the harvesting efficiency of paddy.

[0003] Traditional small rice grain stripping devices have some inconveniences during operation. Usually, the operator needs to manually fix one end of the rice straw and quickly strike the head of the rice straw through a rotating paddle to achieve the stripping of paddy. After the stripping is completed, the operator needs to pull out the rice straw and then hold a new batch of rice for stripping. This method not only has a large labor intensity but also has low efficiency. Summary of the Utility Model

Cooperating with the separation mechanism, the stripping quality can be effectively improved. In addition, roller two can be made of rubber material to avoid crushing the rice grains during extrusion and affecting the quality. Moreover, while rolling, one end of the rice straw can be limited, which is convenient for the separation mechanism to carry out stripping, effectively improving the working stability and convenience, and eliminating the need for manual limitation by personnel.
