Description

Technical Field

[0001] The utility model relates to a seed screening device for cotton cultivation. Background Art

[0002] Chinese patent application number 202221303414.8 discloses a seed screening device for cotton cultivation, which can screen cotton seeds and collect high-quality seeds and impurities separately.

[0003] The patented seed screening device for cotton cultivation comprises: a screening box, a vertical adsorption plate arranged at the bottom of the screening box, a vertical partition arranged at the top of the adsorption plate, lower hoppers arranged on the left and right sides of the top of the partition, a blower mechanism arranged at the top of the left side wall of the screening box (the blower mechanism includes an air duct, a fan and a mesh, etc.), a seed drawer and a debris removal drawer arranged at the bottom of the screening box and arranged on the left and right sides of the adsorption plate (the seed drawer is on the left side of the adsorption plate, and the debris removal drawer is on the right side of the adsorption plate), and a quantitative feeding mechanism arranged on the left side of the top of the screening box (the quantitative feeding mechanism includes a rectangular frame, a roller, a plurality of quantitative slots, a reduction motor and a storage hopper, etc.).

[0004] The working principle of the patented seed screening device for cotton cultivation includes: a quantitative feeding mechanism supplies cotton seeds to be screened into the screening box; a blower mechanism (fan) blows air to the cotton seeds entering the screening box, and high-quality seeds can resist the horizontal airflow and fall into the seed drawer through the left lower hopper, and impurities (light impurities and shriveled and damaged seeds) will be blown by the horizontal airflow to the right lower hopper and fall into the impurity removal drawer, thereby screening the cotton seeds and collecting high-quality seeds and impurities separately; after the screening is completed, the staff will take out the seed drawer and the impurity removal drawer from the screening box, and then pour the high-quality seeds in the seed drawer into other devices for storing high-quality seeds, and pour the impurities in the impurity removal drawer into other devices for storing impurities; and then reinsert the seed drawer and the impurity removal drawer into the screening box.

[0005] Although the seed screening device for cotton cultivation of the patent can screen cotton seeds and collect high-quality seeds and impurities separately, the patent cannot monitor the stacking height of high-quality seeds in the seed drawer, nor the stacking height of impurities in the impurity removal drawer. If the high-quality seeds in the seed drawer are stacked too high (exceeding the height of the top edge of the seed drawer), then in the process of taking the seed drawer out of the screening box, the high-quality seeds whose height exceeds the top edge of the seed drawer may fall on the bottom wall of the screening box, which may cause waste of high-quality seeds and may also affect the reinsertion of the seed drawer into the screening box. If the impurities in the impurity removal drawer are stacked too high (exceeding the height of the top edge of the impurity removal drawer), then in the process of taking the impurity removal drawer out of the screening box, the impurities whose height exceeds the top edge of the impurity removal drawer may fall on the bottom wall of the screening box, which may cause leakage of impurities and may also affect the reinsertion of the impurity removal drawer into the screening box.

[0025] The main control device monitors the stacking height of seeds in the seed drawer 8 through the seed stacking height detection device 16, and the main control device also monitors the stacking height of impurities in the impurity removal drawer 9 through the impurity stacking height detection device 17;

[0026] When the high-quality seeds in the seed drawer 8 are piled up to a preset height (the preset height is lower than the top edge height of the seed drawer 8; the plurality of seed pile height detection devices 16 detect the seed pile height respectively, and as long as one of the seed pile height detection devices 16 detects that the seed pile height reaches the preset height, the main control device determines that the high-quality seeds in the seed drawer 8 have reached the preset height), the main control device controls the seed pile height alarm device 18 to emit an audible and visual alarm;
