Description

Technical Field

[0001] This utility model relates to the field of rice production technology, specifically to a rice sifting device. Background Technology

[0002] Rice is a food made from paddy through processes such as cleaning, hulling, milling, and finishing. The term "chaff" originally refers to the outer husk of the grain, a part of the whole grain, and belongs to the outer layer of the seed. Rice containing chaff is called coarse rice, while rice without chaff is called refined rice. In the process of rice processing, in order to improve the purity of rice, a chaff sieving device is used to remove the chaff from the rice.

[0003] According to Chinese Utility Model Application No. 202420347155.1, a rice processing sieving device is proposed. The utility model describes that "while the motor drives the sieve plate to vibrate linearly, it intermittently drives the two sealing plates to rotate, so that the rice in the feed hopper intermittently passes through the sealing plates and enters the shell, thereby preventing excessive rice from falling onto the sieve plate and improving the rice sieving effect."

[0004] The rice processing bran screening device uses a motor to drive a vibrating screen plate to screen the rice. The rice is located at the top of the screen plate, while the bran passes through the screen plate and falls onto the inner bottom wall of the shell. It is then discharged through two different outlets. However, the bran may adhere to the inner bottom wall of the shell, requiring manual cleaning by workers, which is time-consuming and labor-intensive, affecting maintenance efficiency. Therefore, a rice processing bran screening device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The rice sieving device in this embodiment includes a vibration mechanism 1, a sieving mechanism 2, a feeding mechanism 3, and a cleaning mechanism 4.

[0027] Specifically, the staff first pours the rice into the feeding mechanism 3, then uses the screening mechanism 2 to screen the rice. The screened rice and bran are discharged from the feeding mechanism 3. Finally, the cleaning mechanism 4 is used to clean the bran remaining in the feeding mechanism 3, which saves time and effort and improves maintenance efficiency.

[0028] In this embodiment, the screening mechanism 2 includes a screening chamber 21. A filter plate 22 is detachably installed inside the screening chamber 21. A third annular plate is fixedly installed inside the screening chamber 21. The filter plate 22 is placed on top of the third annular plate.

The top of the filter plate 22 has multiple filter holes, which are evenly and equidistantly distributed. A first discharge pipe 23 and a second discharge pipe 24 are fixedly installed inside the screening chamber 21.

[0029] Specifically, the filter plate 22 screens the rice. The rice is located at the top of the filter plate 22 and is discharged through the first discharge pipe 23. The bran passes through the filter plate 22 and falls onto the inner bottom wall of the screening chamber 21, and is discharged through the second discharge pipe 24.

[0030] In this embodiment, the vibration mechanism 1 includes a frame 11, a first spring 12 is fixedly installed on the top of the frame 11, a horizontal plate 13 is fixedly installed on the top of the first spring 12, the horizontal plate 13 is fixedly connected to the outer wall of the screening chamber 21, a vibration chamber 14 is fixedly installed at the bottom of the screening chamber 21, and a vibration motor 15 is fixedly installed on the outside of the vibration chamber 14.

[0031] Specifically, by turning on the vibration motor 15, the vibration motor 15 drives the screening chamber 21, the filter plate 22, and the horizontal plate 13 to vibrate, and the first spring 12 is deformed by the force.

[0032] In this embodiment, the feeding mechanism 3 includes a feeding bin 31, which is detachably connected to the top of the screening bin 21. A first annular plate is fixedly installed at the bottom of the feeding bin 31, and a second annular plate is fixedly installed at the top of the screening bin 21. The second annular plate is threadedly connected to the first annular plate by a first bolt. A feed pipe 32 is connected to the top of the feeding bin 31, and a movable door 33 is embedded in the top of the feed pipe 32.

[0033] Specifically, when the movable door 33 is opened, the rice enters the interior of the feeding hopper 31 along the feed pipe 32.

[0034] In this embodiment, the cleaning mechanism 4 includes a cleaning chamber 41. A threaded rod 42 is rotatably mounted on the inner wall of the cleaning chamber 41 via a bearing. One end of the threaded rod 42 away from the inner wall of the cleaning chamber 41 passes through the threaded rod 42 and is fixedly mounted on a rotating disk 43. A threaded sleeve 44 is installed on the outer thread of the threaded rod 42. The outer side of the threaded sleeve 44 passes through the screening chamber 21 and is fixedly mounted on a moving rod 45. A moving hole is opened inside the screening chamber 21, and the moving hole matches the moving rod 45. A moving plate 46 is fixedly mounted on the side wall of the moving rod 45. A sliding groove is opened inside the screening chamber 21. A slider matching the moving groove is fixedly mounted on the outer side of the moving plate 46. A cleaning plate 47 that contacts the inner bottom wall of the screening chamber 21 is fixedly mounted on the bottom of the moving plate 46. An inclined plate 48 is fixedly mounted inside the screening chamber 21.

[0035] Specifically, the inclined plate 48 and the moving plate 46 cover the rice bran, so that the rice bran is located on the same side of the moving plate 46, which facilitates subsequent cleaning. By rotating the rotating disk 43, the rotating disk 43 drives the threaded rod 42 to rotate, and the threaded rod 42 drives the threaded sleeve 44, the moving rod 45, the moving plate 46 and the cleaning plate 47 to move. The cleaning plate 47 cleans the rice bran attached to the bottom wall of the screening chamber 21.

[0036] In this embodiment, a positioning mechanism 5 is provided on the rotating disk 43. The positioning mechanism 5 includes a positioning chamber 51, which is fixedly connected to the side wall of the rotating disk 43. A second spring 52 is fixedly installed on the inner side wall of the positioning chamber 51. A connecting plate 53 is fixedly installed on one end of the second spring 52 away from the inner side wall of the positioning chamber 51. A connecting rod 54 that passes through the second spring 52 and the positioning chamber 51 is fixedly installed on one side of the connecting plate 53. A pull block 55 is fixedly installed on the side of the connecting rod 54 away from the second spring 52. A positioning rod 56 that passes through the rotating disk 43 and extends into the cleaning chamber 41 is fixedly installed on the other side of the connecting plate 53.

[0037] Specifically, by pulling the pull block 55, the pull block 55 drives the connecting rod 54, the connecting plate 53 and the connecting plate 53 to move, the second spring 52 is compressed by force until the positioning rod 56 moves out of the cleaning chamber 41, releasing the positioning of the rotating disk 43.

[0038] The working principle of the above embodiments is as follows:

[0039] First, the operator opens the movable door 33, and the rice enters the feeding hopper 31 and screening hopper 21 along the feed pipe 32. Then, the vibration motor 15 is turned on, which drives the screening hopper 21, filter plate 22, and horizontal plate 13 to vibrate. The first spring 12 deforms under pressure, and the filter plate 22 screens the rice. The rice, located at the top of the filter plate 22, is discharged through the first discharge pipe 23.

[0040] The rice bran passes through the filter plate 22 and falls onto the inner bottom wall of the screening chamber 21. The inclined plate 48 and the moving plate 46 shield the rice bran, ensuring that it is all located on the same side of the moving plate 46, and then discharged through the second discharge pipe 24.

[0041] After screening, first turn off the vibration motor 15, then pull the pull block 55. The pull block 55 drives the connecting rod 54, connecting plate 53 and connecting plate 53 to move. The second spring 52 is compressed until the positioning rod 56 moves out of the cleaning chamber 41, releasing the positioning of the rotating disk 43. Finally, rotate the rotating disk 43. The rotating disk 43 drives the threaded rod 42 to rotate. The threaded rod 42 drives the threaded sleeve 44, moving rod 45, moving plate 46 and cleaning plate 47 to move. The cleaning plate 47 cleans the bran adhering to the bottom wall of the screening chamber 21 and discharges it through the second discharge pipe 24. This saves time and effort and improves maintenance efficiency.
