Airflow-assisted plasma seed treatment device

Abstract

The invention discloses an airflow-assisted plasma seed treatment device which comprises a feeding bin, a plasma treatment cavity, an air inlet auxiliary unit, a collecting bin and a high-voltage power supply control module, two connectors are arranged above the plasma treatment cavity, an air channel is arranged below the plasma treatment cavity, the feeding bin and the collecting bin are connected to the connectors above the plasma treatment cavity respectively, the air inlet auxiliary unit is connected to the air channel below the plasma treatment cavity, a suction device is arranged on the upper portion of the interior of the collecting bin, a discharging port is formed in the lower portion of the collecting bin, and the air inlet auxiliary unit, the plasma treatment cavity and the collecting bin are all connected to the high-voltage power supply control module. By means of the air inlet auxiliary unit, wind power is utilized to drive seeds to move in the treatment cavity, uniform treatment of the seeds is achieved, the problem that the treatment effect is poor due to the fact that small-particle-size seeds are prone to accumulation through a traditional method or existing treatment equipment is solved, the seed vitality is improved, and seed germination and growth are promoted.

Description

technical field [0001] The invention belongs to the technical field of seed treatment equipment, and in particular relates to an airflow-assisted plasma seed treatment machine. Background technique [0002] Small seeds (thousand seeds dry weight less than 10g) are often unable to be coated normally due to their small size and very irregular shape, but need to be treated by pellet coating. The mixed powder is applied on the surface of tiny particles or irregularly shaped seeds to change the shape and size, usually into spherical particles, so that the volume of the tiny particles will increase and facilitate sowing, but pelletization If the chemical is over-controlled or improperly operated, it is prone to the threat of yellowing of seedlings and failure of seeds to emerge. [0003] The use of plasma to sterilize small seeds can avoid the problem of phytotoxicity after treatment, and the treatment process is pollution-free and environmentally friendly. Most of the existing p...

Problems solved by technology

[0009] In view of the above problems, the main purpose of the present invention is to design an airflow-assisted plasma seed treatment machine. Through the setting of the air intake auxiliary unit, the wind force is used to drive the seeds to move in the treatment chamber, so as to realize the uniform treatment of the seeds and solve the problem of small particle size. Seeds with small diameters are easy to pile up with traditional methods or current processing equipment, resulting in poor treatment effects, improving seed vigor, and promoting seed germination and growth
