Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice peeling device based on airflow assistance. Background Technology

[0002] Rice production requires the removal of husks and bran to obtain rice with the husks and bran removed, which is then used for further rice processing. The husk removal process is usually accomplished by a rice husk removal device.

[0003] In traditional rice peeling devices, the peeling component inside the device usually picks up all the rice in the feed hopper at once. When the amount of rice input exceeds the processing limit, it is easy to cause some rice to be not fully peeled, which reduces the quality of rice peeling. In addition, the rice obtained after peeling is mixed with the removed husks, which increases the difficulty of separating them and reduces the quality of the final output rice. Utility Model Content

[0004] The purpose of this invention is to provide a rice peeling device based on airflow assistance, which has the advantages of good rice peeling effect and clean separation of rice and husk.

[0005] The technical solution of this utility model is as follows:

[0006] A rice hulling device based on airflow assistance includes a housing. A feeding hopper is located at the top of the housing, and a hulling component is located below the feeding hopper. A distributing component for intermittent feeding is located between the feeding hopper and the hulling component. Below the hulling component, the housing has a separation zone for separating rice and hulls. At the outlet of the distributing component, the separation zone has a material dispersing component for breaking up the mixture of rice and hulls. Below the material dispersing component, the separation zone has an air outlet. Opposite to the air outlet, the separation zone has an air inlet. An exhaust fan is located at the outer end of the air outlet. The outlet of the exhaust fan is detachably connected to a breathable gauze bag for collecting hulls. The bottom of the separation zone is an outwardly sloping surface. At the end of the sloping surface at the bottom of the separation zone, the housing has a discharge port, which is hinged with a sealing door.

[0007] Preferably, the material distribution assembly includes a material distribution roller and a motor A. A material distribution area is provided below the feeding hopper inside the housing. The top and bottom of the material distribution area are respectively provided with inlets leading to the feeding hopper and the peeling assembly. The material distribution area is cylindrical in shape along the horizontal direction. A material distribution roller, coaxial with the material distribution area, is rotatably connected within the material distribution area. The diameter of the material distribution roller is approximately equal to the diameter of the material distribution area. A motor A, with a drive rod coaxially connected to the shaft of the material distribution roller, is provided outside the housing. Several material distribution grooves are evenly distributed along the circumference on the roller surface of the material distribution area. The length direction of the material distribution grooves is the same as the length direction of the material distribution roller.

[0008] Preferably, the peeling assembly includes a peeling roller and a motor B. A peeling zone is located below the feeding zone within the housing. The top and bottom of the peeling zone have openings leading to the feeding zone and the separation zone, respectively. The peeling zone is cylindrical in shape along the horizontal direction. A peeling roller, coaxial with the peeling zone, is rotatably connected within the peeling zone. The inner circumference of the peeling zone is divided into left and right sides by the two openings. One side of the inner circumference of the peeling zone abuts against the surface of the peeling roller, while the other side has a peeling gap between it and the surface of the peeling roller for rice to pass through. The peeling roller at the peeling gap rotates from top to bottom, and the husks on the rice are rubbed off through the rolling action between the peeling roller and the inner circumference of the peeling zone. A motor B, with a drive rod coaxially connected to the rotating shaft of the peeling roller, is located outside the housing.

[0009] Preferably, the bulk material assembly includes a bulk material plate, a rubber rod, and a motor C. The separation zone has an internally and externally communicating mounting port. The bulk material plate is rotatably connected to the mounting port via a spring shaft. The bulk material plate extends out of the housing through the mounting port. The inner end of the bulk material plate is located below the lower end opening of the peeling zone. The motor C is located outside the housing. The drive rod of the motor C is equipped with a rubber rod. The outer end of the bulk material plate is on the rotation trajectory of the rubber rod.

[0010] Preferably, a rice stop plate is provided at the discharge port.

[0011] Preferably, the air inlet is equipped with a filter screen.

[0012] The beneficial technical effects of this utility model are as follows:

[0013] 1. By using a feeding component, the rice is fed to the peeling component in batches, avoiding the problem of incomplete rice peeling caused by feeding too much rice at once and exceeding the processing limit of the peeling component, thereby improving the quality of rice peeling.

[0014] 2. When the hulled rice enters the separation zone along with the husks, the rice and husks are first dispersed by the bulking component to facilitate the separation of the rice and husks. The less dense husks are scattered in the air. At this time, the exhaust fan is activated to draw the air in the separation zone towards the breathable mesh bag. The husks leave the separation zone through the air outlet and stop in the breathable mesh bag. The denser rice is less affected by the air flow and can continue to fall, thus achieving the effect of separating the rice and husks. The rice eventually rolls along the slope to the discharge port. After the staff opens the sealed door, they can take away the rice separated from the husks from the discharge port. Attached Figure Description

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] like Figures 1 to 3 As shown, this embodiment provides a rice peeling device based on airflow assistance, including a box body 1. The top of the box body 1 is provided with a feeding hopper 2, and a peeling component 3 is provided below the feeding hopper 2. A material distribution component 4 that can intermittently feed is provided between the feeding hopper 2 and the peeling component 3. The box body 1 is provided with a separation zone 5 below the peeling component 3 to separate rice and rice husks. The separation zone 5 is provided with a material dispersing component 6 at the outlet of the material distribution component 4 to disperse the mixture of rice and rice husks. The separation zone 5 is provided with an air outlet 7 below the material dispersing component 6. The separation zone 5 is provided with an air inlet 8 at the opposite position of the air outlet 7. The box body 1 is provided with an exhaust fan 9 at the outer end of the air outlet 7. The outlet end of the exhaust fan 9 is detachably connected to a breathable gauze bag 10 for collecting rice husks. The bottom of the separation zone 5 is shaped as an outward downward slope. The box body 1 is provided with a discharge port 11 at the end of the slope at the bottom of the separation zone 5. A sealing door 12 is hinged on the discharge port 11.

[0023] The feeding component 4 feeds rice to the peeling component 3 in batches, avoiding the problem of incomplete rice peeling caused by feeding too much rice at once and exceeding the processing limit of the peeling component 3, thus improving the quality of rice peeling. When the peeled rice enters the separation zone 5 along with the husks, the loosening component 6 first disperses the rice and husks, facilitating the separation of rice and husks. The less dense husks are scattered in the air. At this time, the exhaust fan 9 draws the air in the separation zone 5 to the breathable gauze bag 10. The husks leave the separation zone 5 through the air outlet 7 and stop in the breathable gauze bag 10. The denser rice is less affected by the air flow and can continue to fall, achieving the effect of separating rice and husks. The rice eventually rolls along the slope to the discharge port 11. After the staff opens the sealing door 12, the rice separated from the husks can be taken out from the discharge port 11.

[0024] Furthermore, the material distribution assembly 4 includes a material distribution roller 13 and a motor A14. Inside the housing 1, below the feeding hopper 2, there is a material distribution area 15. The top and bottom of the material distribution area 15 are respectively provided with inlets leading to the feeding hopper 2 and the peeling assembly 3. The material distribution area 15 is cylindrical in shape along the horizontal direction. The material distribution roller 13 is rotatably connected to the material distribution area 15 and is coaxial with it. The diameter of the material distribution roller 13 is approximately the same as the diameter of the material distribution area 15. Outside the housing 1, there is a motor A14 with a drive rod coaxially connected to the rotating shaft of the material distribution roller 13. Several material distribution grooves 16 are evenly provided along the circumference on the roller surface of the material distribution area 15. The length direction of the material distribution grooves 16 is in the same direction as the length direction of the material distribution roller 13.

[0025] The motor A14 drives the distributing roller 13 to rotate at a constant speed. The distributing groove 16 on the distributing roller 13 is used to complete the batch feeding of rice in the feeding hopper 2 and the batch feeding of rice into the peeling component 3. When the distributing groove 16 rotates upward with the distributing roller 13 to the upper opening of the distributing area 15, the rice in the feeding hopper 2 falls into the distributing groove 16 through the opening until the distributing groove 16 is filled. When the distributing groove 16 rotates downward with the distributing roller 13 to the lower opening of the distributing area 15, the rice in the distributing groove 16 falls into the inlet of the peeling component 3.

[0026] Furthermore, the peeling assembly 3 includes a peeling roller 17 and a motor B18. Inside the housing 1, below the distribution area 15, there is a peeling area 19. The top and bottom of the peeling area 19 are respectively provided with openings leading to the distribution area 15 and the separation area 5. The shape of the peeling area 19 is a cylinder along the horizontal direction. The peeling roller 17 is rotatably connected to the peeling area 19 and is coaxial with it. The inner circumference of the peeling area 19 is divided into left and right sides by the two openings. One side of the inner circumference of the peeling area 19 abuts against the roller surface of the peeling roller 17, while the other side has a peeling gap 20 between it and the roller surface of the peeling roller 17 for rice to pass through. The peeling roller 17 at the peeling gap 20 rotates from top to bottom. The husks on the rice are rubbed off by the rolling and rubbing between the peeling roller 17 and the inner circumference of the peeling area 19. Outside the housing 1, there is a motor B18 with a drive rod coaxially connected to the rotating shaft of the peeling roller 17.

[0027] The rice is driven to rotate by motor B18. After falling into the peeling zone 19, the rice is carried into the peeling gap 20 by the rotating peeling roller 17. The rice husk is removed by rolling and rubbing between the peeling roller 17 and the inner circumference of the peeling zone 19. Finally, the mixture of rice and rice husk leaves the peeling zone 19 from the lower end of the peeling zone 19.

[0028] Furthermore, the bulk material assembly 6 includes a bulk material plate 21, a rubber rod 22, and a motor C23. The separation zone 5 is provided with an internal and externally connected mounting port 24. The bulk material plate 21 is rotatably connected to the mounting port 24 via a spring shaft. The bulk material plate 21 extends out of the housing 1 through the mounting port 24. The inner end of the bulk material plate 21 is located below the lower end opening of the peeling zone 19. The motor C23 is provided outside the housing 1. The drive rod of the motor C23 is provided with a rubber rod 22. The outer end of the bulk material plate 21 is on the rotation trajectory of the rubber rod 22.

[0029] The mixture of rice and husks is broken up after hitting the bulk material plate 21, which facilitates subsequent separation. The motor C23 drives the rubber rod to rotate. When the rubber rod rotates to the outer end of the bulk material plate 21, the inner end of the bulk material plate 21, which is hit by the rubber rod, rotates. When the rubber rod rotates to the outer end of the bulk material plate 21, the inner end of the bulk material plate 21 returns to its original position under the action of the spring shaft. The continuous rotation of the rubber rod can realize the reciprocating rotation of the inner end of the bulk material plate 21, thereby better breaking up the mixture of rice and husks, enhancing the separation effect, and preventing rice and husks from remaining on the bulk material plate 21.

[0030] Furthermore, a rice stop plate 25 is provided at the discharge port 11.

[0031] The rice storage tray 25 provides a platform for temporarily storing rice, preventing rice overflow caused by releasing too much rice in a short period of time and not being able to collect it in time.

[0032] Furthermore, a filter screen 26 is installed on the air inlet 8.

[0033] The air inlet 8 is used to supply air from the outside to the separation zone 5, and the filter 26 is used to block impurities contained in the outside air, reducing the risk of rice being contaminated by impurities.

[0034] Working principle and usage process of this utility model:

[0035] Workers attach the ventilation bag 10 to the exhaust fan 9, pour the pre-hulled rice into the feeding hopper 2, and start the material distribution component 4, the hulling component 3, the material dispersing component 6, and the exhaust fan 9. The rice in the feeding hopper 2 is fed into the hulling component 3 in batches by the material distribution component 4. When the hulled rice falls into the separation zone 5, it is broken up by the material dispersing component 6. The husks are drawn into the ventilation bag 10 by the exhaust fan 9. The hulled rice rolls down the slope to the discharge port 11. After the hulling of all the rice is completed, the workers open the sealing door 12 and take the rice out of the discharge port 11, remove the ventilation bag 10 and clean up the accumulated husks inside.

[0036] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
