Silkworm plaque automatic frame lowering device

Abstract

The invention provides an automatic tray-unloading device for a silkworm tray. The automatic tray-unloading device comprises a lift-drop unit and a tray-unloading unit which are in movable fit with guiding structures, wherein the lift-drop unit comprises a first drive motor arranged on a frame and the guiding structures; the rotating output shaft of the first drive motor is connected with a firsttransmission screw structure through a first transmission structure; a first transmission nut structure in screw-thread fit with the first transmission screw structure is arranged on a tray-unloadingunit supporting structure which is in movable fit with the guiding structures; the tray-unloading unit comprises a second drive motor arranged on the tray-unloading unit supporting structure; the rotating output shaft of the second drive motor is connected with a second transmission screw structure through a second transmission structure; a second transmission nut structure in screw-thread fit with the second transmission screw structure is connected with a tray pressing structure; and the bottom part of the tray pressing structure is provided with a bottom frame structure which can match withan upper plane structure of the silkworm tray. The device provided by the invention can realize automatic mechanical operation for replacement of the silkworm tray during feeding and excrement-turning in the process of silkworm breeding, and can realize automatic line production in a large space range, so the efficiency of breeding is effectively improved, and the cost is reduced.

Description

technical field [0001] The invention relates to a device capable of realizing mechanized and automatic replacement of silkworm plaques (silkworm dusters) during silkworm breeding. Background technique [0002] Silkworm breeding has a history of more than 5,000 years in my country, and it is still a traditional backbone project in the rural economy of our country. In the breeding process of silkworms, there are mainly links such as feeding mulberry silkworms, turning sand, and putting them into cages. Foundry is one of the key steps, the purpose is to remove the residual mulberry, silkworm excrement, peeling after sleep and other unclean things accumulated in the silkworm plaque, commonly known as silkworm excrement. If the silkworm excrement accumulates too much and is too thick, the silkworm plaque will steam and heat, emit bad gas, and easily breed pathogenic microorganisms and infect silkworm diseases. Therefore, silkworm excrement must be removed in time to keep the sil...

AI Technical Summary

Problems solved by technology

[0005] In the process of feeding mulberry leaves and turning the sand, the above operations are very cumbersome. Once turning the sand, it is necessary to manually remove the silkworm winnow from the silkworm frame twice.

However, the height of the silkworm racks is different, and it is troublesome to go to the higher and lower places for the silkworm winnowing, which requires a lot of labor and low efficiency.
