Combined injection machine for insect chrysalis

Abstract

The invention discloses an insect pupae group injection machine. Columns are respectively arranged on four corners of a bottom plate. Every column is sequentially provided with a spring, a lifting support plate, an injection depth spacing control block, a needle cylinder lower fixing plate, a needle cylinder upper fixing plate, a needle rod connection plate and a top plate from bottom to top. A lower end surface of the needle cylinder lower fixing plate uses a detachment plate guiding rod to support a pupae detachment plate. A plurality of syringes with equal distance between one another are arranged between the needle cylinder upper fixing plate and the needle cylinder lower fixing plate. Syringe needle rods which are in the same number with the syringes and are arranged with equal distance are positioned between the needle rod connection plate and the needle cylinder upper fixing plate. Needle tips on the lower ends of the syringes can be inserted into respective holes on the pupae detachment plate. A screw rod in the middle of the needle rod connection plate is connected with a jiggle bar screw pair after penetrating the upper end of the top plate. One end of a treading pull rod penetrates the bottom plate and is articulated with the lower end surface of the lifting support plate, and the other end is articulated with a foot board. With simple structure and taking 28 bits as example, the insect pupae group injection machine has the working efficiency which is increased by over 5 times compared with artificial injection. The insect pupae group injection machine is beneficial to the industrialized mass production.

Description

Technical field [0001] The invention relates to an injection machine, in particular to an insect pupa group injection machine. technical background [0002] In recent years, with the development of genetic engineering and transgenic technology, various proteins expressed using baculovirus expression systems have the advantages of high expression efficiency, expression products with the same biological activity as natural proteins, and low production costs. More people know it, especially the use of insect pupa (the most commonly used silkworm pupa) as a bioreactor to produce various medicinal preparations, health products, feed additives and animal vaccines and other genetic engineering products have been more and more widely used . But at present, the production process mainly uses syringes or insect inoculation to manually inoculate pupae one by one. The operation process has the following problems: 1. The amount of labor is large, the time is concentrated, the labor intensity...

Problems solved by technology

But at present, its production process mainly utilizes syringe or insect inoculation to carry out manual inoculation one by one to the pupal body, and there are following problems in the operation process: 1, labor-intensive, time-concentrated, labor-intensive, production efficiency is low; Control, the error is large, resulting in inconsistencies in the response of the pupal body after inoculation, which not only affects the quality of the product, but also increases the follow-up workload; 3. The trauma surface of the pupal body caused by subjective factors during long-term inoculation is easy to cause bacterial mutual infection, increased mortality

These factors hinder the large-scale industrial production of insect pupae as bioreactors
