Description

Technical Field

[0001] The invention relates to a plasma seed uniform processing machine with a multi-stage wind screen cleaning function, belonging to the technical field of agricultural machinery. Background Art

[0002] Seeds are one of the basic materials in the agricultural production process, and seed processing refers to the whole process of various processing of various seeds from harvest to sowing. Harvested forage seeds contain unfilled seeds, broken seeds, immature seeds, insect-eaten seeds, etc., and are also mixed with other crop seeds, weed seeds, straw and soil, sand, dust, etc. Some seeds of grasses often have awns, glumes and other attachments that are difficult to remove. In order to ensure the sowing quality of seeds and the smooth progress of drying and cleaning, the seeds should be de-awned. De-awning can be done by using a de-awning machine or by pressing and screening with a ring roller. There is still a phenomenon of unclean cleaning before seed sowing, so cleaning and grading the seeds again before seed sowing can improve the uniformity and efficiency of plasma treatment.

[0003] Conventional methods for seed pre-sowing treatment include coating, mixing with pesticides, chemical delinting, and soaking seeds with pesticides. These methods play a certain role in sterilization, disease prevention, and yield increase, but are prone to pesticide damage and soil damage. In addition, they cannot truly improve the overall disease resistance, cold resistance, drought resistance, and other stress resistance of the seeds themselves to adapt to the environment. Plasma seed treatment is the most representative physical pre-sowing treatment method. This method simulates the environment in which light, electricity, magnetism, and active particles coexist in space, forcing plasma to bombard the surface of single-grain seeds to achieve the effect of seed surface etching. It can cause microstructural changes in the seed coat, enhance the permeability and water absorption of seeds, and improve the germination potential and germination rate of seeds; high-energy particles that transition into the ion state transfer energy to seeds through collisions or electromagnetic waves, thereby improving seed vitality, extending the growth cycle, and increasing the number of crop mowing times and biological yields; plasma treatment can also enhance resistance to biological and abiotic stresses. This method can enable crops to maintain a good growth advantage throughout the growth cycle and have a positive effect on crop growth.

[0004] The plasma seed uniform treatment machine with multi-stage wind screening cleaning function can realize the graded cleaning and plasma uniform coating treatment of irregular seeds such as alfalfa, and has the function of impurity removal, which can sort seeds in real time and complete impurity removal. At the same time, the sorted seeds are evenly coated with plasma, and the seed surface is bombarded to achieve the effect of etching, thereby enhancing seed vitality and increasing crop yield.
