Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, livestock machinery, and agricultural transportation machinery, etc.

[0003] Chinese patent CN217911530U provides a rapid screening device for seedlings used in agricultural production, including a housing with multiple screening boxes inside. The screening boxes are densely covered with sieve holes, which decrease in size from top to bottom. However, the device screens the seeds by vibration, which may cause the seeds to break during the screening process, affecting the quality of the seeds. It also cannot remove deteriorated seeds or clean the seeds, which may affect breeding.

[0004] Therefore, this utility model provides a seed screening device for agricultural planting to solve the above problems. Utility Model Content

[0029] Example 1

[0030] Reference Figures 1-3 This first embodiment of the present invention proposes a seed screening device for agricultural planting, including a screening barrel 1. Four sets of columns 2 are fixedly connected to the bottom end of the screening barrel 1. A discharge port 3 is fixedly connected to the middle of the bottom end of the screening barrel 1. A drain pipe 4 is fixedly connected to one side of the screening barrel 1. An installation frame 16 is slidably connected to the inner wall of the screening barrel 1. A rotating frame 17 is slidably connected to the installation frame 16. A filter screen 21 is installed on the rotating frame 17. The screening barrel 1 with an opening facilitates the delivery of seeds and brine for washing into the screening barrel 1.

[0031] The inner wall of the screening barrel 1 is provided with two sets of symmetrical sliding grooves 10. Each set of sliding grooves 10 is slidably connected to a slider 15. Both sets of sliders 15 are fixedly connected to the mounting frame 16. The sliding grooves 10 facilitate the sliding of the mounting frame 16 and the sliders 15 along the sliding grooves 10.

[0032] A handle 19 is fixedly connected to the rotating frame 17. Four sets of symmetrical threaded rods 20 are threadedly connected to the rotating frame 17. One end of each threaded rod 20 passes through the rotating frame 17 and is rotatably connected to a clamping plate 18. The clamping plate 18 is slidably connected to the rotating frame 17, and its bottom end is tightly fitted to the filter screen 21. By rotating the threaded rods 20, the clamping plate 18 slides along the rotating frame 17 to fix the filter screen 21, so that the device can replace the filter screen 21 with different pore sizes according to planting needs.

[0033] Two sets of cylinders 22 are fixedly connected to the screening barrel 1. The output ends of the two sets of cylinders 22 are fixedly connected to the slider 15 respectively. By driving the cylinders 22, the mounting frame 16 is driven to rise and fall inside the screening barrel 1, which agitates the salt water and seeds inside the screening barrel 1, making it easier to clean the seeds.

[0034] In this embodiment, the screening barrel 1 with an opening facilitates the delivery of seeds and brine for cleaning into the screening barrel 1. The drive cylinder 22 drives the mounting frame 16 to rise and fall inside the screening barrel 1, agitating the brine and seeds inside the screening barrel 1, which facilitates seed cleaning and effectively avoids seed breakage caused by vibration screening, ensuring the quality of the screened seeds and guaranteeing subsequent agricultural planting. The rotation of the threaded rod 20 drives the clamping plate 18 to slide along the rotating frame 17 to fix the filter screen 21, allowing the device to replace the filter screen 21 with different aperture sizes according to planting needs. The handle 19 on the rotating frame 17 facilitates the rotation of the rotating frame 17, causing the seeds at the top of the filter screen 21 to rotate, making the cleaning more thorough. After cleaning, the drive cylinder 22 drives the filter screen 21 to move vertically, delivering the qualified seeds to the top of the screening barrel 1 for easy seed removal.

[0035] Example 2

[0036] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a mounting plate 5 is fixedly connected to the screening barrel 1, an electric motor 11 is fixedly connected to the mounting plate 5, a drive gear 12 is fixedly connected to the output end of the electric motor 11, and the drive gear 12 is meshed with a driven gear 13; by driving the electric motor 11 to rotate, the drive gear 12 is driven to mesh with the driven gear 13 to rotate.

[0037] A rotating shaft 24 is rotatably connected to the screening barrel 1. The outer wall of the rotating shaft 24 is fixedly connected to the connecting block 23 and the driven gear 13 from bottom to top. A cleaning brush 9 is fixedly connected to one end of the connecting block 23. By driving the driven gear 13 to rotate, the rotating shaft 24 is driven to rotate. The rotation of the rotating shaft 24 drives the connecting block 23 and the cleaning brush 9 to rotate, thereby scraping out chaff, dust, impurities and deteriorated seeds from the seeds in the screening barrel 1.

[0038] A fixing block 6 is fixedly connected to the mounting plate 5. A threaded post 7 is threadedly connected to the fixing block 6. The output end of the threaded post 7 passes through the fixing block 6 and is rotatably connected to an arc-shaped clamping plate 8. The arc-shaped clamping plate 8 is slidably connected to the inner wall of the fixing block 6. By rotating the threaded post 7, the arc-shaped clamping plate 8 is driven to slide along the fixing block 6 to fix the water pipe, which helps to maintain the stability of the water pipe.

[0039] A guide block 14 is fixedly connected to the bottom of the inner wall of the screening barrel 1. The bottom of the guide block 14 is connected to the discharge port 3. The guide block 14 facilitates the discharge of seeds inside the screening barrel 1.

[0040] In this embodiment, the drive motor 11 rotates, causing the drive gear 12 to mesh with the driven gear 13. The density of the deteriorated seeds is less than that of water, so they float on the surface of the screening barrel 1. The driven gear 13 rotates, causing the rotating shaft 24 to rotate. The rotating shaft 24 rotates, causing the connecting block 23 and the cleaning brush 9 to rotate. This scrapes the chaff, dust, debris, and deteriorated seeds from the screening barrel 1, which is beneficial for efficiently screening out high-quality seeds, ensuring that the crops can grow healthily after sowing, and improving yield and economic benefits.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
