Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a screening device for sorghum seed processing. Background Technology

[0002] Large-scale cultivation of sorghum plays an important role in my country's agricultural production. The quality of its seeds directly affects the yield and quality of the crop. In the process of sorghum seed processing, screening is a crucial step to remove shriveled, insect-damaged, moldy, and impurity grains, thereby ensuring the purity, germination rate, and overall quality of the seeds.

[0003] Currently, sorghum seeds are often initially cleaned and graded using methods such as wind separation, screening, or simple water separation in production. However, common water separation methods rely heavily on manual operation, which has problems such as high water consumption, incomplete cleaning, and low operating efficiency. Some existing water separation equipment often has only one function and lacks integrated functions such as impurity separation, water circulation, and automatic conveying, which leads to interruption of the screening process, low degree of automation, and difficulty in meeting the requirements of modern agriculture for high efficiency and high quality in seed processing.

[0027] Working principle: Transportation Process: The operator pours the sorghum seeds to be screened into the water selection tray 22. The device is then started, and the water selection and transportation assembly begins operation: the transport motor drives the first sprocket 2 to rotate, which in turn drives the second sprocket 3 to rotate via a chain, thus rotating the threaded column 10. The main slider 15, which is threaded into the threaded column 10, moves along the main slide rail 16, and through two connecting columns 17, drives the auxiliary sliders 9 on both sides to slide synchronously on the auxiliary slide rail 8, thereby driving the entire hoisting assembly and the water selection tray 22 to move horizontally above the water selection assembly.

[0028] Lifting process: The servo motor starts, driving the two reel mounting columns 13 to rotate synchronously via the sprocket and chain mechanism. The reel 14 releases the rope, smoothly lowering the water selection plate support block 18 and the water selection plate 22 into the overflow tank 19 below the liquid surface for water selection. Plump seeds, due to their high density, sink to the bottom of the water selection plate 22, while chaff, impurities, etc., float on the surface.

[0029] Unloading process: The servo motor reverses, the reel 14 winds up the rope, and the water selection tray 22 is lifted out of the water. Then, the water selection transport assembly restarts, horizontally transporting the water selection tray 22 containing the screened seeds to the unloading position. The operator first twists the water selection tray stop 29 to release the restriction on the water selection tray 22, then rotates the water selection tray mounting column 28 to open the baffle 23 of the water selection tray 22, allowing the screened seeds to be poured out, completing the unloading process.

[0030] Water separation component operation process: The water pump pumps water from the storage tank 4 into the overflow tank 19, forming a water circulation. The drive motor, through the meshing of the first gear 25 and the second gear 26, drives the filter screen column 20 and the filter screen roller 31 to rotate continuously and slowly within the overflow tank 19. Light impurities floating on the water surface of the overflow tank 19 are pushed to one side by the water flow and adhere to the surface of the filter screen roller 31. As the roller rotates, it is scraped off by the cutting edge of the scraping collection box 21 above it and falls into the collection box, maintaining the cleanliness of the water in the water separation process, thereby completing the continuous seed water separation, impurity separation and collection operation.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
