Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and more specifically, to a rice milling structure of a rice hulling and milling combination machine. Background Technology

[0002] The huller is a traditional grain hulling device, shaped like a millstone. It uses the relative rotation of the top and bottom of the huller to grind the grain flowing into the bottom of the huller to remove the husk. Similarly, the mill, which also has a long history, uses grinding force to remove the husk from the grain. However, the mill used for milling is a vertical grinding roller to improve the efficiency of hulling. The existing rice hulling and milling combined rice milling machine combines the hulling structure and the milling structure, thereby reducing the grain processing steps.

[0003] However, existing technologies have some problems: the rice milling structure in existing rice hulling and milling combined machines uses the rotation of iron rollers or sand rollers to allow rice grains to rub and abrade against each other, against the sieve plate, and against the rice rollers to remove the surface bran. However, the sieve plate in existing rice milling structures is usually fixed, and the distance between it and the sand roller is fixed. Therefore, when processing different grains, it is difficult to adjust the distance between the grain and the sand roller according to the characteristics of the grain's surface. Consequently, it is impossible to adjust the collision frequency between different grains and the sieve plate and sand roller to improve the peeling effect, which reduces the applicability. Therefore, we propose a rice milling structure for a rice hulling and milling combined machine. Utility Model Content

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0023] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0024] like Figures 1-5As shown, a rice milling structure of a rice hulling combination rice milling machine includes a barrel body 1. A feed pipe 2 is fixedly installed on the top of the barrel body 1. A guide plate 3 is fixedly connected to the top of the inner wall of the barrel body 1. A drive motor 4 is fixedly installed at the bottom of the guide plate 3. The output shaft of the drive motor 4 is connected to a rotating shaft 5 through a coupling. A sand roller 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A sieve plate 7 is provided inside the barrel body 1 on both sides of the sand roller 6. A slider 8 is slidably connected to both sides of the top of the barrel body 1. A vertical plate 9 is fixedly connected to the bottom of the slider 8. The vertical plate 9 is connected to the sieve plate 7 through a clamping assembly for loading and unloading the sieve plate 7. The slider 8 is connected to the barrel body 1 through a drive assembly. The drive assembly can adjust the distance between the two vertical plates 9 through the slider 8 to accommodate sieve plates 7 of different sizes. Side doors 10 are hinged to both sides of the barrel body 1. A filter plate 11 is fixedly installed at the bottom of the inner cavity of the barrel body 1.

[0025] When the staff needs to adjust the distance between the sieve plate 7 and the sand roller 6 to adjust the grain collision frequency for peeling different grains, the sieve plate 7 can be removed and replaced with a sieve plate 7 of other sizes through the clamping assembly. Then, the distance between the two sieve plates 7 can be adjusted by the drive assembly so that the two sieve plates 7 can be connected end to end to form a cylindrical frame, thereby enabling good peeling processing of different grains.

[0026] The rice milling structure of the above-mentioned rice hulling combination rice milling machine includes a drive component including a brake motor 12, which is fixedly installed on the top of the barrel 1. The output shaft of the brake motor 12 is connected to a round shaft 13 through a coupling. A gear 14 is fixedly connected to the top of the round shaft 13. A rotating plate 15 is slidably connected to the top of the barrel 1. A toothed ring 16 is fixedly installed on the inner wall of the rotating plate 15. The toothed ring 16 and the gear 14 are meshed. Arc-shaped holes 17 are opened on both sides of the top of the rotating plate 15. A round block 18 located inside the arc-shaped hole 17 is fixedly installed on the top of the slider 8.

[0027] By activating the brake motor 12, the round shaft 13 drives the gear 14 to rotate, which in turn causes the gear ring 16 to drive the rotating plate 15 to rotate. This causes the inner wall of the arc-shaped hole 17 to press against the outer surface of the round block 18, thereby causing the two sliders 8 to drive the two vertical plates 9 to move towards or away from each other, thus achieving the adjustment of the distance between the two vertical plates 9.

[0028] The rice milling structure of the above-mentioned rice milling combination rice milling machine includes a clamping component including a square frame 19, which is fixedly installed at the bottom of the vertical plate 9. A threaded rod 20 is threadedly connected to the square frame 19, and a clamping block 21 is rotatably connected to one end of the threaded rod 20 located inside the square frame 19.

[0029] Rotating the threaded rod 20 allows the clamping block 21 to move, thereby clamping and fixing the sieve plate 7 located inside the frame 19. The threaded rod 20 can be a thread type with self-locking characteristics to prevent the clamping from loosening.

[0030] In the rice milling structure of the above-mentioned rice milling combination machine, the inner walls of the clamping block 21 and the square frame 19 are both fixedly installed with pads 22, and the surface of the pads 22 is provided with anti-slip texture.

[0031] The gasket 22 can be made of rubber so that it can adapt to the curved surface of the sieve plate 7 when clamped, and the anti-slip texture on the surface of the gasket 22 can improve the clamping effect.

[0032] The rice milling structure of the above-mentioned rice milling combination machine has electric push rods 23 fixedly installed on both sides of the inner wall of the barrel 1, and the telescopic end of the electric push rods 23 is fixedly connected to a push-pull plate 24.

[0033] Once the two sieve plates 7 are installed and connected, the electric push rod 23 can be activated to make the push-pull plate 24 abut against the joint of the two sieve plates 7, thereby preventing the grain from hitting the sieve plates 7 and causing the joint to open temporarily, resulting in the grain overflowing from the sieve plates 7.

[0034] In the rice milling structure of the above-mentioned rice milling combination machine, the diameter of the round block 18 is matched with the width of the arc-shaped hole 17, and the inner wall of the arc-shaped hole 17 is coated with a lubricating layer.

[0035] By applying a lubricating layer to the inner wall of the arc-shaped hole 17, the circular block 18 can slide more smoothly inside the arc-shaped hole 17.

[0036] Working principle and usage process of this utility model:

[0037] During use, the operator pours grains into the barrel 1 through the feed pipe 2, starts the drive motor 4 to make the rotating shaft 5 drive the sand roller 6 to rotate. When the grains pass between the sand roller 6 and the screen plate 7, there is sufficient friction and rubbing between the grains, between the grains and the screen plate 7, and between the grains and the sand roller 6, achieving dehulling. The dehulled grains slide from the top of the filter plate 11 to the grain outlet, and the husks pass through the filter plate 11 and are discharged from the bottom waste outlet. When the operator needs to adjust the distance between the screen plate 7 and the sand roller 6 to adjust the grain collision frequency for dehulling different grains, the side door 10 can be opened, the threaded rod 20 can be rotated to release the clamp on the screen plate 7, and a screen plate 7 of other sizes can be replaced and the grains can be dehulled again. The frame 19 is fixed to the threaded rod 20. Then, through the drive assembly, by starting the brake motor 12, the round shaft 13 drives the gear 14 to rotate, which in turn drives the gear ring 16 to rotate the rotating plate 15. This causes the inner wall of the arc-shaped hole 17 to press against the outer surface of the round block 18, thereby causing the two sliders 8 to drive the two vertical plates 9 to move towards or away from each other. This allows the distance between the two vertical plates 9 to be adjusted. The distance between the two sieve plates 7 is adjusted according to the size of the sieve plate 7, so that the two sieve plates 7 can be connected end to end to form a cylindrical frame. The distance between the sieve plate 7 and the sand roller 6 is also adjusted, which enables good peeling processing of different grains and improves applicability.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
