[0022] Example:
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A soybean screening device includes two support plates 1. Vertical plates 2 are fixedly installed at the left and right ends of the lower sidewalls of both support plates 1. Transmission mechanisms are installed at the left and right ends between the two support plates 1. A first conveyor belt 3 is commonly installed outside the two transmission mechanisms. A second conveyor belt 4 is sleeved around the first conveyor belt 3. Screen holes are opened on the sidewalls of both the first and second conveyor belts 3 and 4. A fixing mechanism is commonly installed on the sidewalls of both the first and second conveyor belts 3 and 4. Symmetrical fixing rods 5 are fixedly installed on the adjacent sides of the two support plates 1. A guide plate 6 is commonly installed between the two symmetrical fixing rods 5. A holding trough 7 is fixedly installed on the left end of the upper side wall of the support plate 1. A baffle 8 is slidably installed inside the holding trough 7. A horizontal plate 9 is fixedly installed on the right side wall of the holding trough 7. A box 10 is fixedly installed on the lower side wall of the horizontal plate 9. A pressing mechanism is installed inside the box 10. A scraper 11 is evenly arranged at the lower end of the box 10 through the pressing mechanism. This application opens a screen hole evenly arranged on the side wall of the first conveyor belt 3 and the second conveyor belt 4. The size of the screen hole can be adjusted by adjusting the staggered position of the first conveyor belt 3 and the second conveyor belt 4, which facilitates the screening of soybeans of different particle sizes according to the needs of use, making it more convenient to use.
[0025] A collection trough 12 is provided between the two vertical plates 2 and at the lower end of the guide plate 6 to facilitate the collection of screened soybeans and make it easier to process the soybeans in a centralized manner later.
[0026] The transmission mechanism includes a rotating rod 13, which is rotatably mounted between two support plates 1. A motor 14 is fixedly mounted at the rear end of the support plate 1. The rear end of the rotating rod 13 is fixedly connected to the output end of the motor 14. A transmission roller 15 is fixedly mounted on the outside of the rotating rod 13. The inner wall of the first conveyor belt 3 is slidably connected to the side wall of the transmission roller 15. The two motors 14 are asynchronous geared motors, which allows soybeans to be slowly conveyed on the surface of the second conveyor belt 4, facilitating better screening.
[0027] The fixing mechanism includes a U-shaped strip 16, which is fixedly connected to the side wall of the second conveyor belt 4. The lower side wall of the U-shaped strip 16 is threaded with a fastening bolt 17, and the upper end of the fastening bolt 17 is engaged with the lower side wall of the first conveyor belt 3. The width of the U-shaped strip is small, so even when the first conveyor belt 3 and the second conveyor belt 4 move to a position with arcs at both ends, there will be no impact. When the diameter of the transmission roller 15 is large, the bending angle of the first conveyor belt 3 and the second conveyor belt 4 is small, so it will not be affected by the U-shaped strip 16.
[0028] The pressing mechanism includes a slide plate 18, which is slidably connected to the inner wall of the housing 10. A spring 19 is fixedly installed on the upper side wall of the slide plate 18, and the upper end of the spring 19 is fixedly connected to the upper end of the inner wall of the housing 10. A connecting rod 20 is evenly arranged on the lower side wall of the slide plate 18. The evenly arranged connecting rod 20 is slidably connected to the lower side wall of the housing 10 and its lower end is fixedly connected to the upper side wall of the scraper 11. The pressing mechanism can drive the three scrapers 11 to move downward, so that the lower side wall of the scraper 11 contacts the side wall of the second conveyor belt 4.
[0029] The scrapers 11, which are evenly arranged, have strip-shaped openings on their side walls. The lower side wall of the scraper 11 is slidably connected to the side wall of the second conveyor belt 4, which facilitates the turning of the conveyed soybeans, so that smaller soybean particles can fall down through the sieve holes of the first conveyor belt 3 and the second conveyor belt 4.
[0030] Working principle:
[0031] The soybeans to be screened are poured into the container trough 7. Depending on the desired soybean particle size, the position of the second conveyor belt 4 outside the first transmission belt 3 is moved, causing the sieve holes on the side walls of the first and second conveyor belts 3 and 4 to be misaligned, thus adjusting the sieve hole size. After the position of the second conveyor belt 4 is adjusted, the first and second conveyor belts 3 and 4 are fixed by tightening the fastening bolts 17. The baffle 8 is then opened, and the soybeans inside the container trough 7 fall onto the upper end of the second conveyor belt 4. The two transmission mechanisms drive the first and second conveyor belts 3 and 4 to move, and the three scrapers 11 agitate the conveyed soybeans, causing smaller soybean particles to fall through the upper side walls of the first and second conveyor belts 3 and 4 onto the upper end of the guide plate 6 and be collected by the collection trough 12.
