A high-efficiency rice husking machine

Abstract

The invention discloses a high-efficiency paddy hulling machine, which comprises a box body, a rubber roller assembly, a screening assembly and a material guide assembly. The material guide assembly includes two oppositely arranged material guide plates and a The rubber roller assembly is parallel to the material guide roller, and the surface of the material guide roller is provided with material guide teeth. The material parts are parallel to each other, and the distance between the two material guide parts is 1 to 3 times the length of the rice. The rubber roller assembly includes two parallel rubber rollers that rotate in opposite directions and have different outer surface speeds. The rubber rollers include Mutual detachable rollers and rubber sleeves set on the outside of the rollers. The invention has uniform paddy feeding, high husking efficiency and high husking rate of rubber rollers, no clogging of rice, saving time and labor, and ensuring husking efficiency; the rubber rollers are easy to disassemble and assemble, and the cost of maintenance and replacement is low.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and relates to grain shelling equipment, in particular to a high-efficiency rice shelling machine. Background technique [0002] Rice needs to be shelled to obtain edible rice, and rice shelling machines are often used for rice shelling. The existing rice shelling machines are roughly divided into three types: rubber roller type, sand disc type and centrifugal type. Among them, the rubber roller type rice hulling machine is more efficient than the sand disc type due to its high shelling rate, smooth surface of brown rice and less broken rice. And the centrifugal sheller is more widely used. However, because the rubber roller type paddy sheller uses two parallel rubber rollers to squeeze and rub the rice, during the extrusion and rubbing and tearing process, the surface of the rubber rollers is severely worn, if the rice is fed too much at once , The rubber roller is...

AI Technical Summary

Problems solved by technology

However, the structure of the filter box in this patent is relatively complicated. Screening and cleaning the rice before husking will affect the husking efficiency of the rice, and the patent does not specify what kind of husking method to use, and does not solve the problem that the rubber roller is easy to wear

[0004] After searching, it is found that rubber roller wear is an inevitable and common phenomenon. This problem cannot be solved without changing the material of the rubber roller. Therefore, the paddy sheller can only be improved from the perspective of reducing maintenance and replacement costs.
