Technical Field

[0001] The utility model relates to the technical field of rubber roller rice husker, in particular to a rubber roller rice husker with a multi-layer husking mechanism. Background Art

[0002] A rice husker is a grain processing machine that removes the husk of rice and makes it into brown rice. It can remove the outer shell of rice, reduce the risk of rice grains bursting and skin damage, and keep the brown rice intact as much as possible. It is mainly composed of a hopper feeding device, a head device, a husk separation chamber, a gear transmission, a frame, etc. Common rice husker equipment includes rubber roller husker, sand disk husker and centrifugal husker.

[0003] The main working parts of the rubber roller rice husker are a pair of horizontal rubber rollers or plastic rollers bonded or covered with rubber layers on a cast iron cylinder. During the falling process of the rice, due to the squeezing of the two rollers and the rubbing and tearing effect caused by the speed difference of the two rollers, most of the rice is husked, and then enters the husk separation device, and the rice husk is sucked out by the wind at the suction port. The Chinese utility model patent publication number is: CN216063381U, a rubber roller rice husker with a multi-layer husking mechanism, including a machine body, the machine body includes a hollow internal chassis, and a feed A material discharge port is provided on a vertical end surface of one side of the chassis, a stepped material guide plate is fixed on the inside of the chassis through the feeding port and the material discharge port, two rollers are vertically rotatably installed on the horizontal surface of the material guide plate, a motor is vertically fixed on the bottom surface of the horizontal surface of the material guide plate, and the output end of the motor is connected to the rotating shaft of the roller. The above patent has a multi-layer hulling mechanism with a good hulling effect, but when the brown rice enters the rubber roller huller, sand and gravel will be mixed in the brown rice. If the sand and gravel are not processed, it will affect the quality of the finished rice after production. In view of this, we propose a rubber roller huller with a multi-layer hulling mechanism.
