Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of seed screening, especially relates to a soybean planting seed screening device. BACKGROUND

[0002] Soybean is one of the important crops, and is widely used in food processing, oil refining and feed production and other fields. In order to improve the yield and quality of soybean, the screening of seed quality is very important. The screening process of soybean seed is mainly to select the seeds that meet the sowing requirements, and to remove unqualified seeds (such as empty shell, diseased and insect damaged seeds, deformed seeds, etc.), so as to ensure the quality and germination rate of seeds. The traditional seed screening method mostly depends on manual or simple mechanical screening, but these methods have problems such as low efficiency, poor precision and high labor intensity. Therefore, it is an urgent need in agricultural production to develop a high-efficiency and precise soybean seed screening device.

[0003] A soybean planting seed screening device is disclosed in Chinese patent with authorization announcement No. CN221790142U, which comprises a box body, a feed inlet is formed on the top surface of the box body, an L-shaped shell is arranged above the feed inlet, ventilation holes are formed at both ends of the shell and fans are installed, a ventilation plate is fixedly connected above the fans of the vertical section of the shell, a plurality of sieve discs are vertically arranged and slidably arranged inside the box body, openings are formed on the side surface of the box body for the sliding of the sieve discs, and a rotating rod is rotatably arranged below the sieve disc. The soybean planting seed screening device blows the impurities above the ventilation plate through two fans to remove the impurities, and simultaneously drives the rotating rod to rotate through a synchronous assembly to realize the knocking of the eccentric wheel on the sieve disc, thereby realizing the vibration of the sieve disc. Compared with the existing device, the problem that the sieve holes of the sieve disc may be blocked by impurities during the screening process is avoided, and the screening efficiency is improved.

[0004] However, when the structure is in use, the multiple filter screens are easily covered with dust and other impurities after a long period of filtering, which is usually cleaned manually by the staff, which is time-consuming and labor-intensive. Moreover, the dust in the cleaning process can harm the health of the body, causing trouble, and the knocking and vibrating method of the filter screen is low in efficiency and needs to be improved.

This also frees workers from manually cleaning the filter plate 6, avoiding adverse effects on their health and improving the safety of the device.

[0034] The drive assembly includes a dual-axis motor 13 fixedly mounted on the back of the screening shell 1. Both output ends of the dual-axis motor 13 are fixedly connected to a bevel gear 14. The outer wall of the bevel gear 14 is meshed with a bevel gear 15. A threaded rod 16 is fixedly connected to one side of the bevel gear 15. The threaded rod 16 is threadedly connected to a threaded block 7. One end of the threaded block 7 is rotatably connected to a connecting block 17. One side of the connecting block 17 is fixedly connected to the screening shell 1. The blocking assembly includes several baffles 18 movably mounted. Fixing holes 19 are opened on both sides of the baffles 18 and the screening shell 1. Fixing pins 20 are snapped into the fixing holes 19.

[0035] The cleaning assembly includes a drive motor 21 fixedly mounted on one side of a cleaning frame 9 via a bracket. Three rotating shafts 22 are rotatably connected to one side of the cleaning frame 9. A first pulley 23, two second pulleys 24, and a third pulley 25 are respectively fixedly connected to the outer walls of the three rotating shafts 22. The first pulley 23 is connected to one of the second pulleys 24 via belt drive, and the third pulley 25 is connected to the other second pulley 24 via belt drive.

One end of the brush 10 is fixedly connected to the rotating shaft 22. The dust collection assembly includes a dust collection fan 26 fixedly installed on one side of the screening shell 1. A hose 27 is fixedly connected to the dust collection port of the dust collection fan 26. A diverter pipe 28 is fixedly connected to one end of the hose 27. All three ports of the diverter pipe 28 are rotatably connected to the cleaning brush 10. The dust collection port of the dust collection fan 26 is fixedly connected to the through hole 30. A dust collection box 29 is movably installed at the bottom of the inner wall of the screening shell 1. Through holes 30 are opened on one side of both the screening shell 1 and the dust collection box 29. A discharge port 31 is fixedly connected to the top of the screening shell 1.

[0036] Working principle: First, the soybean seeds to be screened are poured into the feed inlet 31, and then the seeds fall onto the filter plate 6. Then, the dual-shaft motor 13 is started, and the two output ends rotate, thereby driving the two bevel gears 14 to rotate, which in turn drives the meshing bevel gear 15 to rotate, causing the threaded rod 16 to rotate, driving the threaded block 7 to move, and then causing the filter plate 6, which is fixed to the threaded block 7, to move. Under the action of the ball bearings 4 on the bottom support plate 2 of the filter plate 6, the filter plate 6 can move more smoothly and reduce the friction caused by the movement. By driving the reverse drive motor 21, the filter plate 6 can be made to reciprocate, so that the seeds on the filter plate 6 can be shaken back and forth, allowing the seeds to be screened. After the screening is completed, the filter plate 6 is reset, and then the fixing pins 20 on both sides of the screening shell 1 are pulled out. The lower part of the baffle 18 is pushed to tilt the baffle 18. Moving it diagonally upwards, the baffle 18 can be taken out. Then, the filter plate 6 can be driven to move outwards, so that the screened seeds can be easily taken out.

[0037] After removing the seeds, if the filter screen needs cleaning, first reset the filter plate 6, then start the cylinder 8. The telescopic end drives the cleaning frame 9 to move, causing the cleaning brush 10 to move to a position away from the surface of the filter plate 6. When not cleaning the filter plate 6, the telescopic end of the cylinder 8 retracts, moving the cleaning brush 10 to the bottom of the filter plate 6 to prevent damage to the device caused by the movement of the filter plate 6 during the screening process. Then, the movement of the filter plate 6 can be controlled, and the drive motor 21 is started. The output end drives pulley 1 23, pulley 24, and pulley 3 25 to rotate via belts, causing the cleaning brush 10 to rotate. At the same time, the vacuum fan 26 is started, and the suction force generated enters the diversion pipe 28 and cavity 12 through the hose 27, and then vacuums the dust through the suction hole 11. While cleaning, the cleaning brush 10 can also adsorb the generated dust. Impurities enter the dust collection box 29 through the through hole 30, thus thoroughly cleaning the impurities on the filter plate 6 and preventing dust from flying around and causing adverse effects on human health, making it easy to use.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
