Description
Technical field
The present invention relates to a kind of device for treatment of seeds, specifically, relate to a kind of seed treatment instrument of cold plasma.
Background technology
In agricultural production, all kinds of crop seeds have a selection and a processing procedure to seed prior to seeding usually, and seed selection and seed treatment have a direct impact the nutrient component of its germination, production, output, fruit.The technology of utilizing plasma that crop seed is handled in recent years is used, as the disclosed a kind of Seed handler of low-temperature plasma of Chinese patent CN1203752C, in cavity, produce vacuum to a certain degree, utilize radio frequency source and induction coil to produce glow discharge, activation to energy in the crop seeds, thereby reach raising output, improve the purpose of product quality.But there is following deficiency in this seed processing machine, adopts induction coil can produce eddy current, magnet short-cut path, causes power consumption to increase severely, and causes energy waste, and treatment effeciency also reduces greatly simultaneously.Abroad have and adopt radio frequency source to connect the technology that two parallel battery lead plates generation glow discharge zones are handled seed, but owing to also can produce glow discharge between two electrode plate and cavity inner wall, cause the waste of the power consumption sharp increase and the energy, and can not between two pole plates, produce the glow discharge zone of concentrating, thereby still very low to the treatment effeciency of crop seed, can't reach obvious effects.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and can not only activate energy in the seed, make percentage of seedgermination improve quality improving, and the high seed treatment instrument of cold plasma of treatment effeciency.
The technical scheme that realizes above-mentioned purpose is: a kind of seed treatment instrument of cold plasma, comprise have charging aperture, the cylindrical shell of discharging opening, vacuum orifice and air inlet, vacuum orifice is connected by pipeline with vavuum pump, the seed conveyer belt that is provided with parallel upper and lower battery lead plate in the cylindrical shell and drives by power set, and the seed conveyer belt passes the zone between the upper and lower battery lead plate, upper and lower battery lead plate is connected with radio frequency source by the radio frequency output line respectively, and the outer periphery of upper and lower battery lead plate is equipped with metallic shield.
After adopting technique scheme, form glow discharge zone between two point pole plates that are connected with radio frequency source by the radio frequency output line, seed on the seed conveyer belt is through this glow discharge zone, electronics, ion, the molecule of excitation state, atom, free radical isoreactivity particle that glow discharge produces, and ultraviolet light, X ray in the crop seeds can activation, the crop germination rate is improved, drought resisting, disease-resistant, growth is vigorous, thereby reach raising output, improve the purpose of product quality.Because the outer periphery of two electrode plate is equipped with metallic shield, this metallic shield can stop between battery lead plate and cylinder inboard wall and produces glow discharge, thereby formed weak plasma slab at metallic shield and cylinder inboard wall, avoided meaningless power consumption, guarantee that glow discharge concentrates between two electrode plate, thereby the treatment effeciency of seed is improved greatly.
