Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a grain polishing machine with high uniformity. Background Technology

[0002] In the post-processing of grains such as rice and Job's tears, after brown rice is milled, the surface of the rice grains still has a small amount of bran powder, which affects the appearance, storage quality, and taste. Polishing helps to completely remove the bran from the surface of the rice grains and also makes the starch on the surface of the rice grains gelatinized, improving the smoothness of the rice grains, which not only improves the appearance but also facilitates preservation.

[0003] Existing grain polishing machines tend to have grains accumulating or clustering at the feed inlet during feeding, and uneven feeding may lead to inconsistent polishing results. Therefore, a grain polishing machine with high uniformity is proposed.

[0004] A rice polishing machine with good uniformity is disclosed in publication number CN220126301U. This rice polishing machine includes: a main body comprising a polishing shell, with a feed inlet fixedly connected to the upper surface of the polishing shell; and a material equalization mechanism including a guide plate fixedly connected to the inner surface of the polishing shell, a connecting plate fixedly connected to the lower surface of the guide plate, a second motor fixedly connected to the surface of the guide plate, an output shaft disposed on the surface of the second motor, and a rotating shaft fixedly connected to the output shaft. The second motor drives the rotating shaft to rotate via the output shaft, and a material equalization plate is fixedly connected to the surface of the rotating shaft. This invention, through the guide plate, connecting plate, second motor, rotating shaft, and material equalization plate, allows rice to enter the polishing roller shaft evenly for polishing, enabling the polishing roller shaft to polish the rice uniformly, reducing the phenomenon of large differences in the texture of polished rice, and facilitating sales for merchants.

[0005] Although the aforementioned patent achieves the goal of ensuring that rice can be evenly fed into the polishing roller shaft through the guide plate, connecting plate, second motor, rotating shaft, and equalizing plate, the material falling is not dispersed enough, resulting in poor effect. Furthermore, the device lacks a buffer and shock absorption mechanism, causing the equipment to vibrate during use. Prolonged vibration can lead to loosening of equipment parts, affecting normal operation. In addition, existing grain polishing machines also suffer from the problem of low efficiency due to manual handling of grains.

[0006] Therefore, it is necessary to invent a grain polishing machine with high uniformity to solve the above problems. Utility Model Content

[0019] (III) Beneficial Effects

[0020] This invention provides a grain polishing machine with high uniformity, which has the following beneficial effects:

[0021] 1. This high-uniformity grain polishing machine, through the setting of the drive mechanism and conveying pipe, when in use, the grain is poured into the conveying port on one side of the conveying pipe, and then the servo motor inside the top motor box is started. The servo motor drives the auger rod on one side to rotate, thereby conveying the grain inside the conveying port to the feed port at the top of the polishing machine body. There is no need for manual handling, saving the physical consumption of workers, and the mechanical transportation is more efficient.

[0022] 2. This high-uniformity grain polishing machine features a dust collection mechanism. During use, impurities are stirred up as the grain exits the discharge port, affecting the surrounding environment. Therefore, a dust collection head is installed directly below the discharge port. Activating the powerful suction fan inside the collection box generates suction at the dust collection head, drawing the stirred-up dust into the collection box for storage, ensuring a clean and tidy surrounding environment.

[0023] 3. This high-uniformity grain polishing machine, through the setting of the swing mechanism, when polishing, the material is conveyed to the feed inlet and enters the surface of the bottom distribution plate. The hydraulic rod on one side of the distribution plate is activated, and the hydraulic rod drives the distribution plate connected to the side to swing left and right. The material on the distribution plate will be evenly spread on the surface of the distribution plate. As the material is fed through the discharge hole on the surface of the distribution plate, it falls into the middle of the two sets of polishing cotton cloth cylinders set directly below for polishing. This makes the material distribution inside the main body of the polishing machine more uniform, thus helping to achieve a more uniform polishing effect. Attached Figure Description

[0036] Please see Figure 2 A conveying port 13 is provided on one side of the conveying pipe 9. The conveying pipe 9 is threaded to the bottom surface, and the conveying port 13 is convenient for placing grains.

[0037] Please see Figure 1 The bottom of the polishing machine body 1 has four sets of threaded holes, and four sets of bolts 14 are connected to the internal threads of the threaded holes. The bolts 14 facilitate the support of the polishing machine body 1.

[0038] Please see Figure 5 The polishing motor 1601 is fixedly connected to the bottom of the polishing machine body 1. The output end of the polishing motor 1601 is fixedly connected to the transmission gear A1602. The surface of the transmission gear A1602 is meshed with the transmission chain 1603.

One side of the material distribution plate 1503 is rotatably connected to the hydraulic rod 1504 through the rotating shaft. The hydraulic rod 1504 facilitates the material distribution plate 1503 to swing left and right.

[0040] The model of the polishing machine body 1 is JPG5; the above parameters and model can be selected according to the actual situation.

[0041] In this invention, the working steps of the device are as follows:

[0042] First step: When using the machine, pour the grain into the conveying port 13 on one side of the conveying pipe 9, and then start the servo motor 1101 inside the top motor box 10. The servo motor 1101 drives the auger rod 1102 on one side to rotate, thereby conveying the grain inside the conveying port 13 to the feed port 8 at the top of the polishing machine body 1.

[0043] The second step: Activate the hydraulic rod 1504 on one side of the material distribution plate 1503. The hydraulic rod 1504 drives the material distribution plate 1503, which is rotatably connected on one side, to swing left and right. The material on the material distribution plate 1503 will be evenly spread on the surface of the material distribution plate 1503. As the material is fed through the discharge hole on the surface of the material distribution plate 1503, it falls into the middle of the two sets of polishing cotton cloth cylinders 1607 set directly below, thereby making the material more evenly distributed inside the polishing machine body 1.

[0044] The third step: Start the polishing motor 1601 at the bottom. The polishing motor 1601 drives the transmission gear A1602 on one side and the transmission chain 1603 meshing on the surface to rotate. The transmission gear B1604 on the upper surface of the transmission chain 1603 rotates together, and drives the main gear 1605 on one side and the auxiliary gear 1606 meshing on the surface of the main gear 1605 to rotate. Finally, the polishing cotton cloth cylinder 1607 fixedly connected to one side of the main gear 1605 and the auxiliary gear 1606 moves relative to each other, which can polish the material conveyed to the middle.

[0045] Fourth step: After the material is polished, dust will be raised when the grain comes out of the discharge port, affecting the surrounding environment. Therefore, a dust suction head 7 is set directly below the discharge port. The powerful suction fan 601 inside the collection box 5 is turned on. The powerful suction fan 601 causes the dust suction head 7 to generate suction to suck the raised dust into the collection box 5 for storage.
