[0003] Soybeans freshly harvested from the field are usually mixed with foreign objects, mud, weeds and other impurities. Traditional screening devices can only screen one type of impurity at a time, and cannot remove both the lighter and heavier impurities from the soybeans at the same time, which affects the screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for soybean harvesting.

[0005] The technical problem solved by this invention is that traditional screening devices cannot simultaneously remove both heavier and lighter impurities from soybeans, which affects the screening efficiency.

[0006] This utility model can be achieved through the following technical solution: it includes a sorting tank and discharge ports on both sides, a water outlet pipe is fixedly connected to the bottom of one side of the sorting tank, a screening plate that can move up and down in the vertical direction is slidably installed in the inner cavity of the sorting tank, support frames are fixedly installed on both sides of the top of the screening plate, a sliding bracket is slidably installed through the two support frames, a sliding plate is slidably connected through the top of the sliding bracket on both sides, a foam board is fixedly installed on the top of the two sliding plates, a brush is fixedly installed at the bottom of the sliding bracket, the bottom of the brush is in contact with the top of the screening plate, and a drive component for driving the sliding bracket to move is installed on the sorting tank.

[0007] A further technical improvement of this utility model is that: discharge plates are fixedly installed at the bottom of both sides of the sorting pool near the discharge port, and collection boxes and waste boxes are fixedly installed at the bottom of both sides of the sorting pool respectively.

[0008] Furthermore, the structure that causes the screening plate to move up and down in the vertical direction includes grooves on both sides of the bottom of the screening plate, rotating plates rotatably installed on both sides of the separation tank, and the ends of the two rotating plates away from the rotating shaft respectively slidingly connected to the two grooves.

[0009] Furthermore, the top of both sides of the foam board is designed with a curved surface.

[0010] Furthermore, the drive assembly includes a threaded rod rotatably mounted on the top of the sorting tank, a movable block slidably connected to the top of the sorting tank through a threaded connection on the threaded rod, and a folding plate rotatably mounted on one side of the sliding bracket, with the end of the folding plate away from the sliding bracket rotatably connected to the bottom of the movable block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This application uses a vertically moving screening plate to flush soybeans in water, causing heavier impurities in the soybeans to sink to the bottom and lighter impurities to float on the surface. After the impurities in the soybeans are separated, the floating impurities are discharged into a waste bin through a foam board, and the separated soybeans are discharged into a collection bin, thus improving screening efficiency.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-3As shown, this embodiment provides a screening device for soybean harvesting, including a sorting pool 1. Discharge ports 2 are provided on both sides of the sorting pool 1. Discharge plates 3 are fixedly installed on the bottom of both sides of the sorting pool 1 near the discharge ports 2. A collection box 4 and a waste box 5 are fixedly installed on the bottom of both sides of the sorting pool 1, respectively. A water outlet pipe 6 is fixedly connected to the bottom of one side of the sorting pool 1, and a valve is installed on the water outlet pipe 6. A screening plate 7 is slidably installed inside the sorting pool 1. Sliding grooves 8 are provided on both sides of the bottom of the screening plate 7. Rotating plates 9 are rotatably installed on both sides of the sorting pool 1. The ends of the two rotating plates 9 away from the rotating shaft are respectively slidably connected to the two sliding grooves 8. A drive motor for driving one of the rotating plates 9 to rotate is installed on the sorting pool 1.

[0020] The rotating plate 9 will drive the screening plate 7 to move up and down in the vertical direction. During this process, the end of the rotating plate 9 away from the rotating shaft will slide in the slide groove 8 to correct the positional relationship between the rotating plate 9 and the screening plate 7. When the screening plate 7 moves to the highest position, the top of the screening plate 7 is just flush with the bottom of the discharge port 2.

[0021] Support frames 10 are fixedly installed on both sides of the top of the screening plate 7. A sliding bracket 11 is slidably installed between the two support frames 10. Slide plates 12 are slidably connected to both sides of the top of the sliding bracket 11. Foam boards 13 are fixedly installed on the top of the two slide plates 12. Both sides of the top of the foam board 13 are set as arc surfaces. A brush 14 is fixedly installed at the bottom of the sliding bracket 11. The bottom of the brush 14 is in contact with the top of the screening plate 7. A threaded rod 15 is rotatably installed on the top of the separation tank 1. A drive motor for driving the threaded rod 15 to rotate is installed on the separation tank 1. A moving block 16 is slidably connected to the top of the separation tank 1 through the threaded rod 15. A folding plate 17 is rotatably installed on one side of the sliding bracket 11. The end of the folding plate 17 away from the sliding bracket 11 is rotatably connected to the bottom of the moving block 16.

[0022] When the threaded rod 15 rotates, it drives the moving block 16 to move horizontally. This causes the moving block 16 to move the sliding bracket 11 synchronously horizontally between the two support frames 10 via the folding plate 17. Consequently, the sliding bracket 11 drives the brush 14 to scrape the top of the screening plate 7, and the sliding bracket 11 drives the foam board 13 to move synchronously via the slide plate 12. When the screening plate 7 moves vertically downward, the folding plate 17 opens as the distance between the sliding bracket 11 and the moving block 16 changes, and conversely, it folds as the distance changes, in order to correct the positional relationship between the folding plate 17, the moving block 16, and the sliding bracket 11. When a certain amount of water is poured into the sorting tank 1, and when the screening plate 7 moves downward below the water surface, the foam board 13 will always float on the water surface, and the foam board 13 will drive the slide plate 12 to slide on the sliding bracket 11, in order to correct the positional relationship between the foam board 13 and the sliding bracket 11.

[0023] In use, this invention first involves adding a certain amount of water to the sorting tank 1, ensuring the water level is flush with the bottom of the discharge port 2. Then, the screening plate 7 is moved below the water surface. Next, the soybeans to be sorted are placed on top of the screening plate 7 in the sorting tank 1. The screening plate 7 is then moved vertically up and down, causing it to wash the soybeans in the water. This causes heavier impurities in the soybeans to pass through the mesh of the screening plate 7 and sink to the bottom, while lighter impurities float on the surface. Finally, the sliding support 11 is moved towards the waste bin 5 to further flush the floating impurities. The foam board 13 on the surface scrapes the impurities floating on the water surface into the waste bin 5. During this process, the sliding support 11 also drives the brush 14 to scrape the soybeans on the screening plate 7 to promote the cleaning of impurities on the soybeans. After the impurities in the soybeans are separated, the screening plate 7 is moved upward to the highest position. Then, the sliding support 11 drives the brush 14 to move towards the collection box 4, thereby prompting the brush 14 to sweep the sorted soybeans on the screening plate 7 into the collection box 4. Finally, the operator puts the soybeans in the collection box 4 into the next process for drying.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
