Description

Technical Field

[0001] This utility model relates to the field of rice screening technology, and in particular to a rice screening device for rice processing. Background Technology

[0002] Rice screening devices in rice processing are key equipment used to grade and remove impurities from paddy rice or rice based on characteristics such as particle size, shape, and density during processing, aiming to improve the purity and quality of rice.

[0003] The rice screening device uses equipment such as vibrating screen, gravity destoner, drum screen, and color sorter to grade paddy rice or rice according to characteristics such as particle size, density, and color, removing impurities such as broken rice, bran powder, stones, and discolored particles, ultimately improving the purity and quality of rice.

[0004] However, the following problems were found in the implementation of the relevant technology: When screening rice, vibrating screens are often used to screen the rice. The vibration drives the rice to move above the vibrating screen, thereby removing impurities or broken rice. However, it may be difficult to move the surface rice to the inner layer of the rice and make it in contact with the screen by simply relying on vibration. In view of this, a rice screening device for rice processing is provided to overcome the above defects. Utility Model Content

[0030] Working principle:

[0031] When using this utility model, the user first presses the operation panel 3 located on the front side of the outer casing 1 to set the operating parameters of the device and its internal components. The user then pours the rice to be screened into the inner side of the outer casing 1 through the inlet 2 located at the top of the outer casing 1. The rice enters the conveying pipe 8 connected to the inlet 2 and is sprayed onto the top of the first sieve plate 10 through a nozzle 7 fixed to one end of the conveying pipe 8. Before pouring in the rice, the user should start the first motor 5 located on the surface of the outer casing 1. The rotation of the output shaft of the first motor 5 drives the swing arm 9 fixed to the output shaft of the first motor 5 to swing left and right. The swing of the swing arm 9 drives the connecting ring 14 and connecting ring 1 fixed to the swing arm 9. The four fixed nozzles 7 swing left and right synchronously, so that the rice to be tested can be evenly sprayed on the surface of the first sieve plate 10, avoiding the rice from piling up in one place and making it difficult to screen the upper layer of rice. At this time, the first electric push rods 6 located at the bottom of the outer shell 1 are activated. There are four first electric push rods 6. By retracting the telescopic rods of two first electric push rods 6 and extending the telescopic rods of the two first electric push rods 6, the connecting sleeves 19 fixed at one end of the telescopic rods of the first electric push rods 6 swing up and down. The connecting sleeves 19 are rotatably connected to the connecting block 20, and the connecting block 20 is fixed to the side of the second sieve plate 16 located below the first sieve plate 10. At this time, the first sieve plate 10 will tilt accordingly, and the side of the first sieve plate 10 that is tilted upward will activate. The second motor 17, fixed to this side, is activated. One end of the second motor 17 is fixed to one side of the fixing block 22, and the top of the fixing block 22 is fixed to the bottom of the first sieve plate 10. The operation of the second motor 17 drives the threaded rod 18 fixed to the second motor 17 to rotate, and the rotation of the threaded rod 18 drives the second sieve plate 16 to move, so that the second sieve plate 16 can rotate as the connecting sleeve 19 moves upward. At this time, the nozzle 7 sprays rice onto the extended second sieve plate 16. When the rice falls to the top of the second sieve plate 16, it will roll to the other side of the sieve plate due to the slope. The left and right sides of the first sieve plate 10 are fixed with inclined blocks 15. The rice on the second sieve plate 16 will roll back to the first sieve plate 10 after passing the inclined blocks 15. After being screened by the first screen plate 10 and the second screen plate 16, defective or impurities in the rice are screened out. These impurities are discharged through the discharge hopper 13 fixed at the bottom of the inner side of the outer shell 1. By making the first screen plate 10 and the second screen plate 16 swing left and right continuously, the rice is continuously rolled, thereby improving the screening efficiency of the rice and avoiding the phenomenon that the inner layer of rice blocks the holes on the screen plate, which prevents the outer layer of rice from being screened. The screened rice is discharged through the discharge chute 21. By tilting the second screen plate 16 to the vicinity of the discharge chute 21 and opening the stop 12 by the second electric push rod 11, the screened rice is discharged from the outer shell 1 through the discharge chute 21. The support leg 4 serves to support the entire device.

[0032] In this utility model, the first motor 5, the first electric push rod 6, the threaded rod 18 and other components are all existing technologies, and their working principle is consistent with that of similar products on the market, so they will not be described in detail here.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
