Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

Referring to fig. 1-3, a rice polishing machine includes: the polishing machine comprises a material barrel 1 with a feeding hole and a discharging hole 10, a planetary gear 5 mechanism, a driving mechanism and a polishing roller, wherein the driving mechanism is fixedly arranged on the material barrel 1, and the output end of the driving mechanism is coaxially and fixedly connected with a rotating shaft 3; planetary gear 5 mechanism is by interior outer sun gear 4, two at least planetary gear 5 and planet carrier 6 of including in proper order, planet carrier 6 and feed cylinder 1 fixed connection, sun gear 4 sets up in planet carrier 6, sun gear 4's middle part and the perpendicular fixed connection of pivot 3, planetary gear 5 meshes with sun gear 4, planet carrier 6 mutually respectively, sun gear 4 perpendicular fixedly connected with in middle part main roll 2, planetary gear 5 perpendicular fixedly connected with in middle part secondary roll 7.

Specifically, before processing, an operator can pour rice into the charging barrel 1 from the feeding hole, and at the moment, the driving mechanism is started, and the driving mechanism drives the rotating shaft 3 to rotate to drive the whole planetary gear 5 system to rotate. It can be understood that, because the planet carrier 6 is fixed on the charging barrel 1, the rotating shaft 3 drives the main roller 2 on the central gear 4 to rotate when driving the central gear 4 to rotate; the planetary gear 5 rotates around the neutral gear, and the planetary gear 5 drives the auxiliary roller 7 thereon to rotate. And the rotation direction of the main roll 2 is opposite to that of the sub-roll 7, and the main roll 2 and the sub-roll 7 bear larger relative friction effect. Simultaneously, the auxiliary roller 7 stirs the rice inside when rotating around the central gear 4, so that the rice grains uniformly flow in the charging basket, and the polishing is more uniform.

The rice polishing machine also comprises a chassis 8 for bearing materials, a connecting rod 11, a diaphragm valve 9 and a spring, wherein a water inlet communicated with an external water source is formed in the charging barrel 1; the chassis 8 is arranged below the inner part of the charging barrel 1, two ends of the spring are respectively connected with the chassis 8 and the inner bottom surface of the charging barrel 1, and the outer edge of the chassis 8 is provided with a flange 12; one end of the connecting rod 11 is fixedly connected with the flange 12, and the other end of the connecting rod 11 is connected with a valve rod 13 of the diaphragm valve 9.

Specifically, in the actual polishing process, it is often necessary to add water to the cartridge 1 during polishing to enhance the polishing effect. Through the arrangement, when more rice grains are in the charging bucket, the pressure borne by the chassis 8 is higher, the position of the chassis 8 is lower at the moon bottom, and when the chassis 8 moves downwards, the valve rod 13 is driven to move downwards, so that the opening of the diaphragm valve 9 is enlarged, and the water inflow is increased. Conversely, when the inner rice grain is reduced, the chassis 8 is raised in position, causing the valve stem 13 to move upwards and the diaphragm valve 9 opening to decrease. Therefore, through this kind of setting, can realize when the grain of rice weight change in the feed cylinder 1, the automatic control inflow flow improves the degree of automation of device.

In addition, the outer edge of the chassis 8 is provided with a sealing ring.

A rotating ring 14 is embedded in the bottom surface of the charging barrel 1, a closed annular groove 15 is formed between the rotating ring 14 and the bottom surface of the charging barrel 1, a plurality of balls 16 are arranged in the annular groove 15, and the rotating ring 14 is rotatably connected with the annular groove 15 through the balls 16; the lower end of the secondary roller 7 is rotatably connected to a rotating ring 14. By providing a rotating ring 14, friction during rotation can be significantly reduced. The connection part of the rotating ring 14 and the secondary roller 7 is provided with a sealing end cover to prevent rice grains from entering the annular groove 15 to influence transmission.

The rice polishing machine also comprises a chassis 8 for bearing materials, the peripheral surface of the chassis 8 is attached to the inner wall of the charging barrel 1, the chassis 8 is provided with a notch 17, and the notch 17 corresponds to the discharging hole 10. In the rotating process, when the notch 17 is aligned with the discharge hole 10, part of rice grains at the bottom can be discharged, so that intermittent discharge can be realized.

The inner wall surface of feed cylinder 1 is equipped with the abrasive material layer, increases the frictional force of 1 inner wall of feed cylinder to the grain of rice.

The discharge port 10 is provided with a filter screen which can filter out large-particle impurities.
