Description

Technical Field

[0001] The present application relates to the technical field of rice husker machines, and in particular to a rice husker machine that is convenient for evenly discharging materials. Background Art

[0002] A rice huller is a grain processing machine that removes the husk of rice and makes brown rice. It can remove the outer husk of rice, reduce the cracking of rice grains and damage to the epidermis, 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. After searching, the patent document with the authorization announcement number CN219482770U announced a uniform feeding type rice huller, including a rice huller body and a collecting box, the interior of the rice huller body is fixedly connected to the outer wall of the collecting box, the top of the rice huller body is fixedly connected to the outer wall of the feed pipe, the interior of the rice huller body is installed with a rubber roller, the exterior of the rice huller body is provided with a uniform feeding mechanism, and the interior of the rice huller body is provided with a screening mechanism. The first bevel gear in the uniform feeding mechanism drives the second bevel gear to rotate, the second bevel gear drives the pin shaft to rotate, the pin shaft drives the disc to rotate, the disc drives the cylinder to slide in the annular groove, the annular groove drives the cross plate to slide in the discharge pipe, and the cross plate is arranged to move in the discharge exchange to open a suitable opening inside the discharge pipe, so that when feeding to the rice husker, the feeding to the rice husker is uniform.

[0003] In actual use, it was found that the above scheme still has at least the following shortcomings: the amount of rice fed is controlled by changing the diameter of the feed pipe by using a horizontal plate, and the rice is easily piled up at the horizontal plate for centralized feeding, which makes it difficult to evenly disperse the rice that falls between the two rubber rollers. The relatively concentrated rice will lead to a poor shelling effect. Moreover, since the feed pipe is located at a certain height, the staff needs to lift a certain amount of rice to a high place each time before pouring the rice into the rice husker body, which requires a lot of labor during operation.

[0004] Therefore, we propose a rice husker that is convenient for evenly feeding to solve the above problems. Utility Model Content

One end of the lifting box 29 is fixedly connected to the top of the U-shaped beam 30. The wire rope 28 can be wound and released by the forward and reverse operation of the winch 27, so as to adjust the height of the lifting box 29. The horizontal position of the lifting box 29 can be adjusted by the horizontal linear sliding of the electric slide 26 on the electric guide rail 25. The blocking assembly includes a baffle 31, a fixing plate 32 and an electric hydraulic cylinder 33. The baffle 31 is slidably installed at the bottom of the lifting box 29.

In specific operation, by controlling the winch 27 to rotate forward, the wire rope 28 can be gradually released, so that the lifting box 29 can be gradually lowered. When the lifting box 29 is lowered to the ground, the winch 27 is stopped, and then an appropriate amount of rice is loaded into the lifting box 29. Subsequently, the winch 27 is controlled to reverse and the wire rope 28 can be gradually reeled in, so that the lifting box 29 gradually rises until it is higher than the feed box 3, and then the winch 27 is stopped.

When the electric slide 26 is controlled to slide to the right on the electric guide rail 25, the lifting box 29 is moved to the right side of the rice husker body 1. By controlling the winch 27 to rotate forward, the lifting box 29 can be lowered to the ground again. According to the above-mentioned operating steps, the feeding box 3 can be continuously filled with rice, so as to realize the effect of lifting the rice from a low position into the feeding box 3.

Under the transmission action of the main pulley 20, the secondary pulley 21 and the belt 22, the first rotating shaft 15 and the second rotating shaft 18 can be controlled to rotate simultaneously, so that the second rotating shaft 18 drives the plurality of material-discharging rods 19 to rotate, and the rice is discharged from the feeding pipe 4. When the rice in the husker body 1 falls, the rotation of multiple material pushers 19 can be used to break up the rice discharged from the discharge pipe 4, so that the rice is scattered more dispersedly on the bulk material mesh plate 14, and the transmission characteristics of multiple cams 16 and the elastic force of four springs 13 can be used to control the vertical reciprocating operation of the bulk material mesh plate 14, so that the rice can pass through the mesh holes on the bulk material mesh plate 14 and fall between the two rubber rollers 2 evenly, so as to avoid the rice from piling up and falling between the two rubber rollers 2, so as to improve the rice husking quality.
