Seed screening device for ecological agriculture and forestry

Abstract

The invention relates to the technical field of ecological agriculture and forestry, in particular to a seed screening device for ecological agriculture and forestry. The seed screening device for ecological agriculture and forestry comprises a box. A feeding opening is formed in the middle of the top of the box. A seal cover is arranged on the feeding opening. Air blowers are symmetrically arranged on the portions, on the left and right sides of the feeding opening, of the top of the box. By means of design and use of a series of structures, in the use process of the seed screening device forecological agriculture and forestry, the phenomenon that only one-grade screening and filtering is conducted on taxus chinensis seeds is avoided, and the screening effect is improved; during screening and filtering, flying dust generated during screening can be collected and processed in time, the phenomenon that screening nets are blocked is avoided during screening and filtering, so that the performance of being not prone to blockage of the seed screening device for ecological agriculture and forestry is further improved, and then the use efficiency of the seed screening device for ecological agriculture and forestry is improved; and in this way, the practicability of the seed screening device for ecological agriculture and forestry is improved.

Description

technical field [0001] The invention relates to the technical field of ecological agriculture and forestry, in particular to a seed screening device for ecological agriculture and forestry. Background technique [0002] Taxus is a general term for plants of the genus Taxus. There are about 11 species in this genus, which are distributed in the northern hemisphere. There are 4 species and 1 variant in China. Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is recognized as a rare and natural anti-cancer plant on the verge of extinction in the world. It is an ancient relic tree species left over from Quaternary glaciers. history. Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time.

Due to the slow growth rate and poor regeneration ability of yew under natural conditions, there has not been a large-scale yew raw material forest base in the world for a long time

[0003] When it comes to the use of seed screening devices for ecological agriculture and forestry, however, the existing seed screening devices for ecological agriculture and forestry only perform primary screening and filtering on the yew seeds during use, resulting in poor screening effect, and when performing screening and filtering At the same time, when screening and filtering, the screen is prone to clogging, which reduces the use efficiency of the seed screening device for ecological agriculture and forestry, thereby reducing the quality of the seed screening device for ecological agriculture and forestry. Therefore, it is urgent to develop a seed screening device for ecological agriculture and forestry to solve the above problems
