Conveying device and conveying method for seed sterilization treatment using electron rays

Abstract

The invention provides a conveying device and a conveying method for seed sterilization treatment using electron rays. The conveying device comprises: a frame, wherein a stock bin, a first conveying line, a sliding channel, a first electron curtain accelerator, and a second electron curtain accelerator are arranged on the frame; the stock bin is located on the upper side of one end of the first conveying line; the sliding channel is located on the lower side of the other end of the first conveying line, and the sliding channel comprises a V-shaped inlet close to the first conveying line, wherein a vertically-downward guide plate is arranged at the end, away from the first conveying line, of the V-shaped inlet; the first electron curtain accelerator and the second electron curtain accelerator are located on the two sides of the guide plate. According to the invention, the seed conveying treatment efficiency is high, it is guaranteed that seeds can be irradiated by electron beams uniformly in all directions, and the energy of the electron beams only acts on the surfaces of the seeds to kill bacteria and viruses on the surfaces of the seeds by adjusting the energy of the electron beams while the activity of the seeds is not damaged.

Description

technical field [0001] The disclosure belongs to the technical field of agricultural equipment, and in particular relates to a conveying device and method for electron beam seed sterilization treatment. Background technique [0002] Good seeds are the basic guarantee for a good agricultural harvest. Seed sterilization can prevent and control seedling pests and diseases, increase seed germination rate, increase seedling nutrition, promote growth and development, reduce costs, reduce environmental pollution, and achieve high quality and high yield; traditional seed treatment technologies such as heat treatment The efficiency of chemical treatment, radiation treatment, etc. is low, and it is harmful to environmental pollution; the use of electron beams to irradiate the surface of seeds, and the penetration depth can be controlled by adjusting the energy level of electron beams, can achieve the purpose of inhibiting germs on the surface of seeds without harming embryos. ; The el...

AI Technical Summary

Problems solved by technology

[0003] The inventors of the present disclosure have found that the existing electronic ray seed sterilization system / device has the following problems: 1. Patent CN108271467A discloses a device and method for killing insects and sterilizing the surface of plant seeds. Treating plant seeds with non-penetrating electron beam characteristics can achieve the purpose of killing insects and sterilizing seeds on the surface without affecting the germination potential and germination rate of seeds; however, the seeds are conveyed in the first and second sections of the rectification channel When the seeds pass the corner, the direction changes, and some seeds will have the problem that the same side surface is irradiated by the upper and lower electron curtain accelerators, but the other side surface cannot be irradiated, and there is also a phenomenon that the seeds block each other and cannot be irradiated. The bactericidal effect is poor; 2. In some devices, the seeds are allowed to pass through the irradiated area in a free-fall manner, and the seeds may block each other, making the treatment difficult to be uniform; 3. In other devices, the seeds are transported through the irradiated area by a conveyor belt , the seed position is fixed, and only one side is irradiated
