Description

Technical Field

[0001] The utility model relates to the field of rice processing, in particular to a rice dandruff removing device for rice processing. Background Art

[0002] Rice processing is to separate rice grains into husks, cortex, embryo and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the minimum degree of crushing to make rice with better edible quality. During the rice processing, the rice needs to be cleaned. In the prior art, after removing the rice husk during rice processing, a large amount of husks will be mixed in the rice, and then a dandruff removal device is needed to remove the rice husks in the rice.

[0003] At present, the commonly used method is to use a fan to blow out wind to disperse and separate the fallen rice dandruff mixture. However, in actual use, the rice is directly placed in the feed hopper, which makes it inconvenient to adjust the feeding speed, and thus cannot be adjusted according to the actual dandruff attached to the rice, resulting in problems such as unclear dandruff removal and low efficiency. For example, when there is a lot of dandruff and the feeding speed is too fast, more rice will pass through the wind at the same time, resulting in the wind being unable to blow all the dandruff out of the rice, affecting the dandruff removal quality.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0020] like Figures 1 to 3 The rice chip removing device for rice processing shown in the figure comprises a chip removing box 1, which is connected to a feed hopper 13 and a guide plate 3, the guide hopper is located at the lower side of the feed hopper 13, the chip removing box 1 is rotatably connected to a threaded rod 11, the threaded rod 11 is threadedly connected to an adjusting plate 14, the adjusting plate 14 abuts against the bottom of the feed hopper 13, and thus can close the feed port at the bottom of the feed hopper 13, the inner side wall of the chip removing box 1 is provided with a limiting slide groove 12, the adjusting plate 14 is slidably connected to the limiting slide groove 12, and the adjusting plate 14 can be rotationally limited by the limiting slide groove 12, the left and right sides of the chip removing box 1 are respectively provided with an air inlet 6 and an air outlet 20, the chip removing box 1 is connected to a fan 8, and the fan 8 can blow air flow through the air inlet 6 and the air outlet 20, the chip removing box 1 is provided with a first discharge port 2 and a second discharge port 5, and the chip removing box 1 is connected to a feeding device.

[0021] The feeding device includes a feeding pipe 15, which is connected to the chip removal box 1. The feeding pipe 15 is connected to the feeding hopper 21, the servo motor 16 and the discharge pipe 17. The outlet of the discharge pipe 17 is located above the feed hopper 13. The output shaft of the servo motor 16 is connected to the auger screw shaft 18. The auger screw shaft is located on the inner side of the feeding pipe 15 and is rotatably connected to the feeding pipe 15. The auger screw shaft and the feeding pipe 15 cooperate with each other.

[0022] The air inlet 6 and the air outlet 20 are respectively connected to the dustproof net 7, the cross-section of the feed hopper 13 is in the shape of a U, the guide plate 3 is connected to the partition 4, the partition 4 is provided with several groups, the guide plate 3 is connected to the sealing plate 19, the sealing plate 19 is connected to the chip removal box 1, the threaded rod 11 is connected to the fixed disc 10, and the fixed disc 10 is connected to the rotating handle 9.

[0023] The specific implementation process is as follows:

[0024] When in use, the servo motor 16 drives the Jiaolong spiral shaft to rotate, and the rice to be de-crumbed enters the feeding hopper 21. Under the action of the Jiaolong spiral shaft, the rice is sent from the discharge pipe 17 into the feed hopper 13. The fixed disc 10 is rotated by turning the handle 9 to drive the threaded rod 11 to rotate. Since the limiting slide 12 has a rotation limiting effect on the adjustment plate 14, the adjustment plate 14 moves left or right along the threaded rod 11 as the threaded rod 11 rotates, thereby adjusting the speed of the small material. The rice falls from the feed hopper 13 and then falls on the guide plate 3. At the same time, the fan 8 is started. The fan 8 blows air, and the air flows from left to right. The mixture of rice and dandruff falls from the guide plate 3 and performs free fall motion, and then is affected by the wind force blown by the fan 8. Since the rice itself is heavy, it is less affected by the wind force, so the rice will continue to fall directly and then fall out from the second discharge port 5, while the dandruff is greatly affected by the wind force, so it will be blown to the right by the fan 8 for a distance, and then fall out from the first discharge port 2, completing the dandruff removal; during this period, the discharge speed and wind force can be controlled according to the actual situation to adapt to the rice dandruff mixture in different situations.

[0025] The technical solution is provided with an adjustment plate 14, through which the feeding speed can be adjusted. The feeding speed can be reasonably adjusted according to the amount of dandruff carried in the rice, thereby improving the efficiency and quality of dandruff removal. At the same time, the wind force of the fan 8 can be reasonably adjusted according to the type of rice, etc., and the feeding speed can be adjusted to improve the quality and efficiency of dandruff removal, thereby greatly improving the applicability of the dandruff removal device. The adjustment can be completed by rotating the threaded rod 11, and the structure is simple and easy to use. A feeding device is provided, and there is no need for users to lift the rice to feed, thereby reducing manual labor intensity and facilitating use. The dustproof net 7 is used to prevent external dust from entering , and at the same time prevent dandruff from flying out of the dandruff box 1, so that the dandruff can be stably discharged from the first discharge port 2, which is convenient for subsequent collection and use; the mouth-shaped feeding hopper 21 allows the rice to fall and discharge evenly in a straight line, avoiding the problem of more accumulation in the middle and less accumulation on both sides, improving the quality of dandruff removal, and further ensuring that the rice can fall evenly in a straight line through the partition 4; the fixed disc 10 and the rotating handle 9 are convenient for users to rotate the threaded rod 11, which is more labor-saving and the adjustment of the discharge is more stable; the sealing plate 19 allows the airflow to move horizontally, avoiding the wind blowing at will, and improving the dandruff removal effect.
