Description

Technical Field

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

[0002] Harvested rice grains need to undergo initial cleaning and impurity removal before they can be stored and enter the subsequent production process. This process removes impurities, improves the edible quality of the grain, and reduces the load on subsequent production equipment.

[0003] Existing rice cleaning devices often use electromagnets to attract iron filings from the rice. However, once the task of attracting the iron filings is completed, the traditional method is to cut off the power to make the electromagnet lose its magnetic force, allowing the attracted iron filings to fall off naturally. However, even after the power is cut off, some iron filings may still adhere to the surface of the electromagnet and are difficult to completely detach, thus affecting the subsequent rice cleaning effect. Therefore, a rice cleaning device is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-4 As shown, the present invention proposes a rice cleaning device, including a screening box 13. The inner wall of the screening box 13 is provided with a first screening plate 5 and a second screening plate 14 spaced apart vertically. The bottom of the screening box 13 is provided with a discharge hopper 7. Support components are symmetrically distributed on the lower sides of the outer end face of the screening box 13. The upper end face of the screening box 13 is connected to the connecting hopper 3 through a connecting pipe 4. The upper end face of the connecting hopper 3 is connected to the feeding hopper 1 through a removal frame 9. The connecting pipe 4 is provided with a collection mechanism, and the removal frame 9 is provided with an iron filings removal mechanism. The first screening plate 5 and the second screening plate 14 are both inclined. The first screening plate 5 is inclined to the left, and the second screening plate 14 is inclined to the right.

[0027] In this invention, when cleaning rice, multiple electromagnet columns 15 are first energized, and then rice is poured in from the top opening of the feed hopper 1 and enters the interior of the removal frame 9. At this time, the multiple electromagnet columns 15 will attract iron filings in the rice. Then, the rice will fall into the interior of the screening box 13 through the connecting hopper 3 and the connecting pipe 4. The rice is then separated from impurities by the first screening plate 5 and the second screening plate 14 inside the screening box 13. The first screening plate 5 can separate large impurities, and the second screening plate 14 can separate smaller impurities. The smaller impurities can fall downward through the second screening plate 14 and are finally discharged through the discharge hopper 7.

[0028] In an optional embodiment, the scrap removal mechanism includes an electromagnet column 15, a removal component, a connecting frame 10, and a moving component. The moving component is located on the outer end face of the removal frame 9. Multiple electromagnet columns 15 are equidistantly distributed on the inner wall of the removal frame 9. The removal component is slidably sleeved on the outer end face of the multiple electromagnet columns 15. One end of the connecting frame 10 is connected to the moving end of the moving component, and the other end of the connecting frame 10 passes through the upper end face of the removal frame 9 and is connected to the removal component.

[0029] It should be noted that when cleaning the iron filings on the outer end faces of the multiple electromagnet columns 15, the multiple electromagnet columns 15 are first de-energized, then the collection mechanism is activated, and then the moving component is started. The moving component can drive the removal component to move through the connecting frame 10. When the removal component moves, it can remove the iron filings remaining on the multiple electromagnet columns 15. The removed iron filings will fall into the collection mechanism. The discharge port at the bottom of the feed hopper 1 is adapted to the opening at the top of the removal frame 9, so that when cleaning the rice, the removal component is located at one end of the multiple electromagnet columns 15, so that the rice will not directly contact the removal component when it falls.

[0030] In an optional embodiment, the removal assembly includes a removal sleeve 17 and a connecting plate 16. Multiple removal sleeves 17 are slidably fitted onto the outer end face of the electromagnet column 15. Multiple adjacent removal sleeves 17 are connected to each other through the connecting plate 16. One end of the connecting frame 10 is connected to the outermost removal sleeve 17. The moving assembly includes a drive motor 11, a moving block 18, a mounting frame 2, and a threaded rod 19. The mounting frame 2 is located on the side of the outer end face of the removal frame 9. The threaded rod 19 is rotatably connected to the inner wall of the mounting frame 2. The drive motor 11 is located on the outer end face of the mounting frame 2. The output shaft of the drive motor 11 passes through the outer end face of the mounting frame 2 and is connected to one end of the threaded rod 19. The moving block 18 is fitted onto the outer end face of the threaded rod 19, which is threaded to it. The other end of the connecting frame 10 is connected to the outer end face of the moving block 18. The electromagnet column 15 has a cylindrical structure, the removal sleeve 17 has a hollow cylindrical structure, and the threaded rod 19 is arranged parallel to the electromagnet column 15.

[0031] It should be noted that when the drive motor 11 is started, the drive motor 11 can drive the threaded rod 19 to rotate. When the threaded rod 19 rotates, it can drive the moving block 18 to move. The moving block 18 can drive the removal sleeve 17 connected to it to move through the connecting frame 10. Then, through multiple connecting plates 16, multiple removal sleeves 17 can be driven to move on multiple electromagnet columns 15, thereby cleaning the iron filings remaining on the multiple electromagnet columns 15.

[0032] In an optional embodiment, the collecting mechanism includes an alignment slot 20, a second handle 24, a drawer 12, and a partition assembly. The alignment slot 20 is formed on the inner end face of the connecting pipe 4. The drawer 12 passes through the opening on the side of the connecting pipe 4 and extends into the interior of the alignment slot 20. The partition assembly is located at the opening on the side of the connecting pipe 4. The second handle 24 is located on the outer end face of the drawer 12 and away from the alignment slot 20. The partition assembly includes a mounting groove 22, a baffle 21, and a first handle 23. The mounting groove 22 is formed on the inner top wall of the opening on the side of the connecting pipe 4. The baffle 21 is inserted into the interior of the mounting groove 22. The first handle 23 is located on the outer end face of the baffle 21.

[0033] It should be noted that when it is necessary to clean the iron filings on multiple electromagnet posts 15, the first handle 23 drives the baffle 21 to move upward inside the mounting groove 22, and then the drawer 12 is inserted into the alignment slot 20. At this time, when cleaning the iron filings on multiple electromagnet posts 15, they will fall into the drawer 12. Then, by pulling the second handle 24, the drawer 12 is pulled out. At this time, the baffle 21 will move downward due to gravity, so that the baffle 21 contacts the inner bottom wall of the side opening of the connecting pipe 4. At this time, the rice can be cleaned.

[0034] In an optional embodiment, the support assembly includes a side plate 6 and support columns 8. The side plate 6 is disposed on the outer end face of the screening box 13, and a plurality of support columns 8 are spaced apart at the bottom of the side plate 6.

[0035] It should be noted that the multiple support columns 8 can support the side plate 6, and the side plates 6 on both sides can provide stable support for the screening box 13.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
