Plasma bean seed treatment device for corona discharge under normal pressure

Abstract

The invention discloses a plasma bean seed treatment device for corona discharge under normal pressure, which comprises a box body, a first shell and a second shell are sequentially sleeved above the box body, a partition plate is arranged at the upper part of the box body, a ground electrode is arranged above the partition plate, an insulating brush is arranged above the ground electrode, the insulating brush is driven by a motor, the ground electrode comprises a metal disc, a pull groove is formed in the metal disc, a metal plate is arranged in the pull groove, a notch is formed in the box body, one end edge of the metal plate is located outside the notch, a high-voltage electrode is arranged at the top end of the second shell, the high-voltage electrode and the ground electrode discharge in the first shell and the second shell, a tank body is arranged on the side of the box body, a material storage box is arranged in the tank body, a continuous blanking tank is arranged at the position corresponding to the material storage box on the partition plate, and the upper part of the blanking tank corresponds to the metal plate. According to the plasma bean seed treatment device, through cooperation of the high-voltage electrode and the ground electrode, bacteria and viruses on the surfaces of seeds are effectively killed, the seed vigor is enhanced, the economical efficiency of seed treatment is improved, and the seeds are treated more evenly and comprehensively in cooperation with rotation of the insulating brush.

Description

technical field [0001] The invention belongs to the technical field of seed treatment equipment, and in particular relates to a plasma bean seed treatment device under normal pressure corona discharge. Background technique [0002] Seeds are the "chips" of modern agriculture and the "source" to ensure national food security and high-quality agricultural and rural development. Seeds are the carrier of crop genetic factors, and the vitality of seeds will affect the growth and development of plants and the level of yield. In agricultural production, the seeds are generally treated before sowing to kill the germs carried by the seeds, prevent and control pests and diseases at the seedling stage, alleviate the decline in seed vigor caused by the process of growth, harvest, and storage, and restore the vigor of the seeds to a certain extent. Seed germination rate, increase seedling nutrition, and promote growth and development, so as to achieve the purpose of seedlings, seedlings,...

Problems solved by technology

[0003] At present, the commonly used seed treatment method is chemical method. Seeds are treated with fungicides, insecticides, plant growth regulators, and biological source preparations. Chemical products can sterilize the surface of seeds and increase crop yields to a certain extent. However, the use of chemical products will cause long-term damage to the soil and water quality environment, and will also have harmful effects on the human body through the food chain, and it is difficult to improve the overall performance of seeds such as disease resistance, drought resistance, and cold resistance.
