Furthermore, the equipment is complex in structure, inconvenient to use, and increases the maintenance cost of the device. Therefore, this invention designs an agricultural seed screening device to solve the above problems. Utility Model Content

[0010] The technical effects and advantages of this utility model are as follows:
[0011] 1. This utility model uses a motor-driven rotating shaft to rotate a long plate. The long plate rotates the seeds in the dust collection box to the direction of the feed pipe and falls into the screening box. During the rotation, the seeds drive the rotating drum and brush to rotate as they pass through the trough. The brush cleans the seeds and removes impurities adhering to the seed coat.

Seeds falling into the secondary screen plate are processed in the same way, realizing multi-stage automatic screening and automatic discharge of seeds. The device has a simple structure and is easy to operate, while reducing the maintenance and replacement costs of the device in the later stages. Attached Figure Description

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The agricultural seed screening device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Reference Figures 1-4This utility model provides an agricultural seed screening device, including a dust collection box 1. The top of the dust collection box 1 has a feed inlet 3, and the bottom of the dust collection box 1 has several filter holes 12. A motor 2 is fixedly installed at the top of the dust collection box 1, and a rotating shaft 9 is fixedly connected to the output end of the motor 2. Several long plates 13 are fixedly connected to the outer wall of the rotating shaft 9 corresponding to the dust collection box 1. The long plates 13 are in contact with the inner wall of the dust collection box 1. Several through grooves 18 are opened at the bottom of the dust collection box 1. A rotating cylinder 19 is rotatably connected within the through grooves 18. Several brushes 20 are fixedly connected to the outer wall of the rotating cylinder 19. The brushes 20 do not contact the inner wall of the through grooves 18, and the highest point of each brush 20 does not exceed the top of the through groove 18. Motor 2 drives shaft 9 to rotate long plate 13. Long plate 13 rotates the seeds in dust collection box 1 to the direction of feed pipe 8 and fall into screening box 7. During rotation, as the seeds pass through through groove 18, they drive rotating drum 19 and brush 20 to rotate. Brush 20 cleans the seeds and removes impurities adhering to the seed coat. These impurities rotate with long plate 13 against the bottom of dust collection box 1 and are discharged from dust collection box 1 through filter hole 12, thus achieving the purpose of dust removal from the seeds and improving the accuracy of subsequent seed screening. Screening box 7 is located on the lower side of dust collection box 1, and the bottom of shaft 9 is rotatably connected to screening box 7. Dust collection box 1 and screening box 7 are connected. Several support columns 4 are fixedly connected between the dust collector 1 and the screening box 7. A feed pipe 8 connects the dust collector 1 and the screening box 7. A main screen plate 14 and a secondary screen plate 16 are fixedly connected to the upper and lower sides of the inner wall of the screening box 7, respectively. Several main screen holes 15 and secondary screen holes 17 are respectively passed through the top of the main screen plate 14 and the secondary screen plate 16. The radius of the main screen holes 15 is larger than the radius of the secondary screen holes 17. Several short plates 10 are fixedly connected to the outer wall of the rotating shaft 9 corresponding to the main screen plate 14 and the secondary screen plate 16. The short plates 10 are in contact with the inner wall of the screening box 7. After dust removal, the seeds enter the screening box 7 and fall on the main screen plate 14. The short plates 10 on the outer wall of the rotating shaft 9 continue to drive its rotation. The radius of the seeds is smaller than that of the main screen holes 15. Seeds fall onto the secondary screen plate 16 through the main screen hole 15. Seeds with a radius larger than the main screen hole 15 continue to rotate with the short plate 10 until the short plate 10 rotates them to the ramp 11 on the other side to complete the automatic discharge. Seeds falling into the secondary screen plate 16 are discharged in the same way. This realizes the multi-stage automatic screening and automatic discharge function of seeds. The device has a simple structure and is easy to operate. At the same time, it reduces the maintenance and replacement costs of the device in the later stage. The main screen plate 14 and the secondary screen plate 16 are both provided with ramps 11 on one side of the top. The feed pipe 8 and the ramps 11 are located horizontally on both sides of the screening box 7. The outer wall of the screening box 7 is provided with discharge troughs 5 corresponding to the ramps 11. The lower side of the outer wall of the screening box 7 is provided with a discharge port 6.
[0020] The working principle of this utility model is as follows: Seeds enter the dust collection box 1 through the feed inlet 3. The motor 2 drives the rotating shaft 9 to rotate the long plate 13. The long plate 13 rotates the seeds in the dust collection box 1 to the direction of the feed pipe 8 and falls into the screening box 7. During the rotation, when the seeds pass through the through groove 18, they drive the rotating drum 19 and the brush 20 to rotate. The brush 20 cleans the seeds and removes impurities adhering to the seed coat. These impurities rotate with the long plate 13 against the bottom of the dust collection box 1 and are discharged from the dust collection box 1 through the filter hole 12, thus achieving the purpose of dust removal from the seeds and improving efficiency. The subsequent seed screening accuracy is improved. As the dust-removed seeds enter the screening box 7 and fall onto the main screen plate 14, the short plate 10 on the outer wall of the rotating shaft 9 continues to drive its rotation. Seeds with a radius smaller than the main screen hole 15 fall onto the secondary screen plate 16 through the main screen hole 15, while seeds with a radius larger than the main screen hole 15 continue to rotate with the short plate 10 until the short plate 10 rotates them to the other side of the slope 11 to complete the automatic discharge. Seeds falling into the secondary screen plate 16 are treated in the same way, realizing multi-level automatic screening and automatic discharge of seeds. The device has a simple structure and is easy to operate, while reducing the maintenance and replacement costs of the device in the later stage.
