Description

Technical Field

[0001] The utility model relates to the technical field of rice husker machines, in particular to a rice husker machine capable of slowing down the wear of a rubber roller. Background Art

[0002] The rice husker is a grain processing machine that removes the husk of rice and makes brown rice. The machine can remove the husk of rice, reduce the cracking of rice grains and the damage of the skin, 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 box, a frame, etc. It can remove the husk of rice, reduce the cracking of rice grains and the damage of the skin, and keep the brown rice intact as much as possible, while reducing the size and energy consumption of traditional models, providing convenience and practicality for household and small and medium-sized commercial rice husker.

[0003] At present, after the rice is collected, it needs to be husked by a rice husker. The rice husker squeezes the rice particles through the differential rotation of the rubber roller, and the husk is peeled off under the action of pressure and friction. Since the processing of rice by the rice husker requires continuous contact and friction between the rubber roller and the rice particles, it is easy to cause wear on the surface of the rubber roller, resulting in a reduction in the service life of the rubber roller. Therefore, the rubber roller needs to be replaced frequently, which is very inconvenient. In view of this, we propose a rice husker that can slow down the wear of the rubber roller. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a rice husker that can slow down the wear of the rubber roller, so as to solve the technical problems that the surface of the rubber roller is easily worn and the service life is relatively low during the operation of the current rice husker.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a rice husker capable of slowing down the wear of the rubber roller, comprising a rice husker body in which a rubber roller assembly is rotatably arranged;

[0006] The rubber roller assembly includes a core shaft with a sleeve detachably provided on the outside, an airbag cover detachably provided on the outer edge surface of the sleeve, and a threaded groove is provided on the inner edge surface of the sleeve, a rubber roller body detachably provided on the outer edge surface of the airbag cover, a plurality of groups of rubber protrusions are constructed on the inner edge surface of the rubber roller body, and the plurality of groups of rubber protrusions are distributed in a spiral shape, threaded teeth are constructed on the outer edge surface of the core shaft, and the core shaft and the sleeve are detachably connected through the threaded cooperation of the threaded teeth and the threaded groove.

[0007] Preferably, a feed hopper connected to the interior of the rice husker body is constructed on one side of the top of the body, and a guide plate 1 is constructed on the top of the inner wall of the body of the rice husker on one side of the feed hopper, and a guide plate 2 is constructed on the top of the inner wall of the body of the rice husker on the other side of the feed hopper, and a feed trough for rice to fall is formed between the guide plates 1 and 2.

[0008] Preferably, a dredging component is rotatably arranged at the position of the discharge chute, and the dredging component includes a rotating shaft with one end rotatably connected to the inner wall of the rice husker body, and a threaded portion is constructed on the outer edge surface of the rotating shaft.

[0009] Preferably, a door slot is provided on one side of the rice huller body, a door panel is installed in the door slot through a hinge, and a handle is provided on one side of the door panel.

[0010] Preferably, a mounting groove is provided at the bottom of one side of the rice huller body, and a collecting box is movably provided at the bottom of the inner wall of the rice huller body, one end of the collecting box extends into the mounting groove, and a handle second is fixedly provided in the center of one side of the collecting box extending to the mounting groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting the airbag cover, the husk on the surface of the rice can be peeled off under the action of the differential rotation of the rubber roller assembly. In the process of the rubber roller body contacting and pressuring the rice, the reaction force generated by the contact between the rice and the rubber roller body acts on the surface of the rubber roller body, so that the rubber roller body is compressed and squeezes the airbag cover, so that the airbag cover shrinks and deforms at the compressed position. The deformation effect of the airbag cover is used to reduce pressure and buffer the rubber roller body, thereby reducing the wear caused by extrusion and friction during the contact between the rice and the rubber roller body, which is beneficial to extending the service life of the rubber roller body.

[0013] 2. By arranging rubber protrusions on the inner edge surface of the rubber roller body, it is helpful to increase the friction between the rubber roller body and the airbag cover, thereby avoiding relative sliding between the rubber roller body and the airbag cover during the process of peeling the husks on the surface of the rice, thereby reducing the wear and damage on the surface of the airbag cover caused by sliding friction. The rubber protrusions are arranged in a spiral shape, which is helpful to improve the stability of the airbag cover installed in the rubber roller body. BRIEF DESCRIPTION OF THE DRAWINGS
