Hepialus armoricanus egg screening device

Abstract

The invention discloses a hepialus armoricanus egg screening device, which comprises a scattering box, falling passages, separation passages and egg receiving boxes, wherein the falling passages are communicated with the scattering box; the separation passages are communicated with the falling passages; the egg receiving boxes are arranged below the separation passages, and comprise a plurality of egg receiving cavities; egg separation ports are formed in the bottoms of the separation passages, and are communicated with the egg receiving cavities respectively; hepialus armoricanus eggs with different sizes are screened to different egg receiving cavities through the egg separation ports. When the screening device works, the hepialus armoricanus eggs with different sizes are placed in the scattering box, fall to the separation passages through the falling passages, and are screened to the egg receiving cavities corresponding to the corresponding egg separation ports through the egg separation ports below the separation passages; therefore, the hepialus armoricanus eggs with corresponding sizes can be screened only by regulating the sizes of the egg separation ports. According to the hepialus armoricanus egg screening device, the hepialus armoricanus eggs can be automatically screened; compared with a manual screening mode in the prior art, the automatic screening mode has the advantages that the working efficiency is improved, and the labor intensity of a worker is reduced.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on December 7, 2012, the application number is 201210524039.4, and the title of the invention is "a device for screening bat moth eggs", the entire content of which is incorporated in this application by reference . technical field [0002] The invention relates to the technical field of Cordyceps sinensis cultivation, in particular to a bat moth egg screening device. Background technique [0003] Cordyceps sinensis is a symbiont of insects and fungi. It is the larvae of bat moths infected by the fungus of Cordyceps sinensis. It uses the organic matter in its body as a nutritional energy source for parasitic life. After continuous growth, development and differentiation, the mycelium finally kinks and forms subseats to protrude from the host shell. Thus forming a special symbiotic organism of insects and fungi. It is a traditional precious and nourishing Chines...

Problems solved by technology

[0006] However, in the prior art, manual screening is used for the sorting of bat moth eggs. When cultivating Cordyceps sinensis on a large scale, millions or even hundreds of millions of bat moth eggs are used each time for manual screening. On the one hand, the labor intensity is too high; on the other hand, the work efficiency is too low
