Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a polishing device used in rice processing. Background Art

[0002] After brown rice is milled, a small amount of bran powder still remains on the surface of the rice grains, which affects the appearance quality, storage quality and taste of the rice. By adding an appropriate amount of water for "polishing", it is helpful to completely remove the rice bran on the surface of the rice grains, and it can also gelatinize the starch on the surface of the rice grains, improve the smoothness of the rice, and improve the appearance of the rice while facilitating its preservation.

[0003] The Chinese patent with the announcement number CN217568846U discloses a surface polishing device for rice processing, including a machine body, a feed hopper is fixedly installed on one side of the top of the machine body, a dust collection box is fixedly installed in the middle of the top of the machine body, a dust collector is installed on one side of the dust collection box, a liquid storage box is fixedly installed on the other side of the top of the machine body, a water pump is fixedly installed inside the liquid storage box, fixed net cylinders are fixedly installed on both sides of the inner wall of the machine body, one side of the top of the fixed net cylinder is fixedly connected to the bottom of the feed hopper, and a polishing shaft is rotatably connected inside the fixed net cylinder. The utility model is convenient for wetting rice during the rice polishing process through the water pump installed inside the liquid storage box and the dust collector installed on one side of the dust collection box, which reduces the rice from being crushed due to excessive temperature during the polishing process, and at the same time, the dust generated by polishing is sucked into the dust collection box through the vacuum cleaner for centralized treatment, effectively ensuring the quality of rice.

Therefore, the orbital speed of the planetary gear inside the device can be adjusted through the arc damping member, so that the device can adapt to different types of rice raw materials.

[0034] In this embodiment, the device can effectively improve the uniformity and thoroughness of rice surface processing, avoiding the problem of different polishing degrees due to uneven distribution of rice raw materials. Compared with the traditional device, the dynamic shaft design of the device can increase the working range of the device. At the same time, the symmetrical distribution of the polishing part 20 and the shovel plate 21 can effectively improve the processing uniformity of the device.

[0035] When the device is in working state, the rice raw material enters into the drum 8 from the feed hopper 12 , and the threaded protrusions 16 on the inner wall of the drum 8 can drive the rice raw material to the position of the discharge hole 10 as the drum 8 rotates.

[0036] When the rice raw material enters the drum 8, the rotating motor 13 and other structures on the mounting plate 4 can drive the driving gear 17 to rotate. The combination of the driving gear 17, the driven internal gear ring 18 and the planetary gear 19 can achieve the effect that the driving gear 17 is active, the driven internal gear ring 18 is driven by self-rotation, and the planetary gear 19 is driven by self-rotation while revolving. The driving shaft processing effect of the device is achieved, the polishing processing effect is achieved when the polishing member 20 passes the bottom of the drum 8, and the vertical turning effect is achieved when the shovel plate 21 passes the bottom. The guide plate and the through-hole structure of the collecting bucket 22 can improve the collection effect of the device for rice.

[0037] When the rice raw material is discharged from the discharge hole 10 into the collecting bucket 22, the collecting bucket 22 can reduce rice splashing and reduce raw material loss. The combination of the through hole at the bottom of the collecting bucket 22 and the air outlet pipe 24 can be used to select the rice during its falling process, so that the powder produced by polishing is separated from the rice raw material partition plate 26 to prevent the powder from being mixed with the rice raw material for the second time.

[0038] The rice raw material passes through the rotating cover 11 from the feed hopper 12 into the drum 8. At this time, the rice is at the bottom of the drum 8. The transmission belt 14 is driven to rotate by the rotating motor 13, and the rotating shaft 15 is driven to rotate by the transmission belt 14. The driving gear 16 is driven by the rotating shaft 15 to rotate. The driving gear 16 drives multiple sets of planetary gears 19 to revolve and rotate at the same time. The multiple sets of planetary gears 19 drive the driven inner gear ring 18 to rotate. At this time, the arc damping member 6 is driven to slide linearly by the threaded rod 7, and the arc damping member 6 is controlled The rotational resistance of the drum 8 is increased, thereby realizing the rotational speed control of the drum 8. The threaded protrusions 16 on the inner wall of the drum 8 drive the rice to move toward the discharge hole 10, and the rice falling from the discharge hole 10 is collected by the collecting bucket 22. The rice raw material continues to fall through the through holes inside the collecting bucket 22. At this time, the blower 23 and the air outlet pipe 24 can generate lateral wind perpendicular to the falling direction of the rice, so as to remove the fine dust in the rice during the falling process, and finally the clean rice raw material is stored in the collecting box 25.

[0039] Embodiment 2

In this embodiment, the width of the collecting bucket 22 is greater than the diameter of the drum 8, and a guide plate is provided on the bottom of the collecting bucket 22, and the guide plate faces the direction of the collecting box 25.

[0041] The structure of the collecting bucket 22 can gather the scattered raw materials, thereby avoiding the waste of rice raw materials during the air selection process.
