Description

Technical Field

[0001] This utility model belongs to the technical field of vaccine production equipment, specifically, it relates to an egg embryo shelling knife. Background Technology

[0002] Eggs are used as a culture medium in vaccine production. The virus is injected into the egg, and after antibodies are produced, the sample solution is extracted and stored in a storage tank. The storage tank is connected to the research institute laboratory through pipelines. According to the vaccine production process, the vaccine production equipment needs to disinfect the surface of the egg, then inject the virus into the egg, and after antibodies are produced, the antibodies in the egg need to be extracted and stored. Finally, the waste eggshells are processed. The eggshell peeling machine needs to peel off the top of the eggshell on the egg lifter so that the harvester head can enter the eggshell to extract the antibody solution. To quickly and conveniently peel off the top of multiple eggshells, an eggshell peeling knife is provided. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide an eggshell peeling knife, which solves the problem of the lack of peeling knives that can be used with eggshell peeling machines in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model discloses an eggshell peeling knife, including: a knife holder and a blade; the knife holder has a frame beam, and guide slides are provided at both ends of the frame beam. The bottom surface of the frame beam is provided with multiple spaced mounting grooves, and the top surface of the mounting grooves is provided with threaded holes. The bottom surface of the frame beam is provided with extensions extending forward and backward, and the edges of the extensions are cutting edges one; the blade is cuboid in shape and is installed in the mounting grooves. The two ends of the blade extend out of the knife holder, and the two ends of the blade are pointed, with the two edges forming the pointed corners being cutting edges two. A through hole is provided in the middle part of the blade.

[0005] Furthermore, the aforementioned tool holder is provided with six mounting slots.

[0006] Furthermore, the surface where the cutting edge of the aforementioned extension is located is an inclined surface.

[0007] Furthermore, the surfaces where the cutting edges at both ends of the aforementioned blade are located are inclined surfaces.

[0008] Furthermore, the thickness of the aforementioned blade is greater than the depth of the mounting groove.

[0009] Furthermore, one end of the aforementioned through hole is provided with a tapered countersunk head.

[0010] Compared with the prior art, this application can achieve the following technical effects:

[0011] The blade holder of this utility model is set on the upper part of the positioning plate of the shell peeler. The positioning holes on the positioning plate position the eggs on the egg lifter. Under the action of the driving device, the shell peeler sweeps across the positioning plate and peels the eggs. This allows for quick and convenient one-time shell peeling of a large number of eggs, improving operational efficiency.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description
