Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a pneumatic adjustable rubber roller rice huller. Background Technology

[0002] The rubber roller rice huller is a common type. It mainly uses two rubber rollers that rotate in opposite directions with a certain speed difference. When the rice passes between the two rubber rollers, the rice is squeezed and torn due to the difference in linear speed between the two rubber rollers. The rice husks will separate from the brown rice due to the different frictional forces.

[0003] A search revealed that the patent, CN220835703U, entitled "Utility Model of Rice Hulling Machine," includes a rice hulling machine. Research and analysis revealed that although it can reduce rice bran during the hulling process, thereby improving rice quality, it also has the following drawbacks to some extent.

[0004] For example, it lacks a fine-tuning function. Because it cannot fine-tune the spacing between the rubber rollers, it cannot flexibly adapt to different varieties, moisture levels, and fullness of rice, leading to frequent occurrences of incomplete or excessive hulling. At the same time, it lacks an anti-clogging function. During the rice hulling process, rice husks easily adhere to the surface of the filter screen. As processing continues, the filter screen gradually becomes clogged, severely hindering the smoothness of rice processing. In order to solve the above technical problems, we designed a pneumatic adjustable rubber roller rice huller. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatically adjustable rubber roller rice huller with the advantages of fine adjustment and anti-clogging functions. It solves the problems of existing rice hullers that cannot fine-tune the spacing between the rubber rollers according to the actual use, and cannot regularly shake off and clean the rice husks attached to the filter screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic adjustable rubber roller rice huller, comprising a housing, with cylinders bolted to the front and rear sides of the inner cavity of the housing, the output end of the cylinder penetrating the housing and bolted to a frame, a servo motor bolted to the front of the frame, rectangular holes provided on both sides of the front and rear of the housing, rubber rollers movably connected to the inner cavities of the rectangular holes, first guide plates riveted to both sides of the inner cavity of the housing, a partition plate riveted to the bottom of the first guide plate on the right side, a collection mechanism bolted to the right side of the bottom of the inner cavity of the housing, the collection mechanism comprising a spring, a collection box bolted to the top of the spring, a collection pipe connected to the left side of the collection box, a collection cover fixedly connected to the top of the right side of the partition plate, and fans bolted to the front and rear sides of the right side of the housing.

A collection cover 13 is fixedly connected to the top of the right side of the partition 8. A fan 14 is bolted to the front and rear sides of the right side of the housing 1.

[0023] Please see Figure 1 and Figure 4The left end of the collection pipe 12 is connected to the collection cover 13. A first sealing plate is bolted to the front side of the collection box 11. A vibration motor 15 is bolted to the left side of the top of the collection box 11. Dampers 16 are bolted to the four corners of the bottom of the collection box 11. The bottom of the dampers 16 is bolted to the inner wall of the box body 1. The dampers 16 are located in the inner cavity of the spring 10. Filter screens 17 are movably connected to the top of both sides of the inner cavity of the collection box 11 via slide rails. The bottom of the inner cavity of the collection box 11... The two sides of the part are riveted with second guide plates 18. The bottom of the collection box 11 is connected to a rectangular tube 19. An elongated hole is opened on the right side of the bottom of the box 1. The bottom end of the rectangular tube 19 passes through the elongated hole. By setting the elongated hole, the bottom of the rectangular tube 19 can pass smoothly through the box 1 without affecting the subsequent vibration operation of the collection box 11. The bottom of the rectangular tube 19 is fitted with a tube cap. The air inlet pipe of the fan 14 is connected to the exhaust pipe 20. The left end of the exhaust pipe 20 passes through the box 1 and is connected to the collection box 11.

[0024] Please see Figure 3 The front sides of the housing 1 are bolted with second sealing plates. The second sealing plates facilitate the user to disassemble and replace the filter screen 17. Support legs are riveted to the four corners of the bottom of the housing 1.

[0025] Please see Figure 1 and Figure 2 The output end of the servo motor 4 passes through the frame 3 and is fixedly connected to the front end of the rubber roller 6. The rear end of the rubber roller 6 is movably connected to the inner wall of the frame 3 through a bearing.

[0026] Please see Figure 1 The top of the box 1 is fixedly connected to a hopper 21, and the bottom of the box 1 is connected to a discharge pipe 22. By setting the discharge pipe 22, it is convenient to discharge the hulled rice.

[0027] Please see Figure 1 A grid plate 23 is riveted to the left side of the bottom of the inner cavity of the box 1. By setting the grid plate 23, the rice husks and rice can be blocked, preventing them from falling to the left side of the bottom of the inner cavity of the box 1. The top of the grid plate 23 is riveted to the first guide plate 7 on the left side. A dustproof net 24 is inlaid and installed at the bottom of the left side of the box 1. By setting the dustproof net 24, outside air can enter the inner cavity of the box 1 when the collection cover 13 sucks up the rice husks. Under the action of the dustproof net 24, the dust contained in the air can also be filtered.

[0028] Please see Figure 1 The top of both sides of the inner cavity of the box 1 is riveted with inclined plates. By setting the inclined plates, the rice can be guided. The plates are located on the top of the rubber roller 6.

[0029] In use, connect the device to an external controller and power supply. When the rice grains are large, the distance between the two rubber rollers 6 needs to be increased. The external controller controls the cylinder 2 to work, and the output of the cylinder 2 drives the frame 3 to move. The two frames 3 move in opposite directions, and the frames 3 drive the servo motor 4 and the rubber rollers 6 to move, thereby fine-tuning the distance between the rubber rollers 6. Then, the external controller controls the servo motor 4 to run, and the output of the servo motor 4 drives the rubber rollers 6 to rotate, conveying the rice into the inner cavity of the hopper 21. The hopper 21 conveys the rice to the top of the rubber rollers 6, where the rubber rollers 6 dehull the rice. The dehulled rice husks and rice are conveyed to the bottom of the first guide plate 7. At this time, the external controller... The blower 14 is controlled to operate, and the blower 14 creates a negative pressure in the cavity of the collection box 11 through the exhaust pipe 20. At this time, the rice continues to fall under the action of gravity and is discharged to the bottom of the box 1 through the discharge pipe 22. The lighter rice husks are sucked into the cavity of the collection box 11 through the collection cover 13 and the collection pipe 12. The filter screen 17 filters the rice husks. After all the rice in the hopper 21 has been dehulled, when it is necessary to clean the rice husks attached to the surface of the filter screen 17, the external controller controls the vibration motor 15 to work. The vibration motor 15 drives the collection box 11 to vibrate, and the collection box 11 drives the filter screen 17 to vibrate, thereby shaking off the attached rice husks. Then the pipe cap is opened, and the rice husks are discharged from the rectangular pipe 19.

[0030] In summary, this pneumatic adjustable rubber roller rice huller, through the cooperation of cylinder 2, frame 3, servo motor 4, rectangular hole 5, rubber roller 6, collection mechanism 9, spring 10, collection box 11, and collection pipe 12, solves the problems of existing rice hullers that cannot fine-tune the spacing between rubber rollers according to actual usage conditions, and cannot periodically shake off and clean the rice husks adhering to the filter screen surface.
