Self-screening type ultraviolet mutagenesis device for biological breeding

Abstract

The invention discloses a self-screening type ultraviolet mutagenesis device for biological breeding. The self-screening type ultraviolet mutagenesis device comprises a device shell, a rotating disc, a first large conveying pipe, a stir-frying plate and an ultraviolet lamp tube, wherein a servo motor is welded and fixed to the device shell, the output end of the servo motor is rotationally connected with a fixed shaft, a worm gear is connected with light insulation plates through screws, and the light insulation plates are movably connected in light insulation frames; the light insulation frames are connected in the device shell through the screws, light transmission holes are formed in the light insulation frames, and the ultraviolet lamp tube is installed in the light insulation frames through bolts. The self-screening type ultraviolet mutagenesis device for the biological breeding is provided with the light insulation frames, a worm can drive the light insulation plates to rotate in the light isolation frames through the worm gear, and the light transmission holes can be shielded to different degrees under the rotation action of the light insulation plates, so that irradiation intensity of the ultraviolet lamp tube can be conveniently and quickly adjusted, and the use stability and convenience of the device are improved.

Description

technical field [0001] The invention relates to the technical field of biological breeding, in particular to a self-screening ultraviolet mutagenesis device for biological breeding. Background technique [0002] Agricultural biotechnology refers to the use of biotechnology such as genetic engineering, fermentation engineering, cell engineering, enzyme engineering, and molecular breeding to improve the production traits of animals, plants, and microorganisms, to cultivate new varieties of animals, plants, and microorganisms, and to produce new biological pesticides, veterinary drugs, and vaccines. Mutation breeding in molecular breeding refers to the breeding method of obtaining new biological varieties by artificial mutagenesis, and there are many methods of artificial mutagenesis, among which the most commonly used and easiest method is ultraviolet radiation mutagenesis, the principle of which is Cells, tissues (plant seeds), organs or organisms that are undergoing cell div...

Problems solved by technology

[0007] The purpose of the present invention is to provide a self-screening ultraviolet mutagenesis device for biological breeding to solve the problem that the ultraviolet mutagenesis device for biological breeding in the market cannot perform stable screening, classification and placement of seeds of different sizes. , when seeds of uneven size are subjected to ultraviolet radiation mutagenesis work at the same time, the uniformity of light received by each seed cannot be guaranteed, and accumulation between seeds is easy to occur, resulting in poor mutagenesis effect, which reduces work efficiency and cannot Problems with stacked seeds for stable heat dissipation
