Positioning overturning type silkworm cocoon rack

Abstract

A positioning overturning type silkworm cocoon rack comprises a fixing support, a hollow support and silkworm cocoon frames, wherein the fixing support is of a cuboid frame structure, the hollow support is rotationally connected with the fixing support, the silkworm cocoon frames are arranged in the hollow support, fastening plates which are connected in an intersecting mode are arranged on the diagonals of a group of parallel side faces of the fixing support, and a positioning ring is arranged in the position of connection of the two fastening plates; the hollow support is formed by fixedly connecting an outer rectangular frame and an inner rectangular frame, the center line of the outer rectangular frame coincides with the center line of the inner rectangular frame, the plane where the outer rectangular frame is located is perpendicular to the plane where the inner rectangular frame is located, each silkworm cocoon frame is of a rectangular frame structure, a plurality of boxes composed of a plurality of longitudinal bars and transverse bars are arranged in each rectangular frame, and the silkworm cocoon frames are vertically arranged in the hollow support side by side. Due to the positioning overturning type silkworm cocoon rack, the silkworm cocoon frame overturning angle can be autonomously adjusted, and the silkworm cocoon quality is improved.

Description

technical field [0001] The invention relates to a silkworm cocoon frame, in particular to a positioning flip type silkworm cocoon frame. Background technique [0002] Silk is a high-grade fabric raw material in people's life, and most of the silk is extracted from silkworm cocoons. The existing cocooning method of silkworm cocoons is to place mature silkworms that are about to spin silk evenly in a large dustpan manually, and then take out the silkworm cocoons one by one from the dustpan after they spin silk and form cocoons. This rough method will cause The silk cocoons stick to each other, which reduces the cocoon rate and affects the silk quality. Another method is to use a cocoon frame with grids. After placing the mature silkworms on the cocoon frame, under physiological characteristics, the mature silkworms will crawl upwards. If the cocoon frame is not turned, all of them will be concentrated on the upper part of the cocoon frame Cocoon making will also cause cocoon...

Problems solved by technology

The existing cocooning method of silkworm cocoons is to place mature silkworms that are about to spin silk evenly in a large dustpan manually, and then take out the silkworm cocoons one by one from the dustpan after they spin silk and form cocoons. This rough method will cause Cocoons stick to each other, which reduces the cocoon rate and affects silk quality

Another method is to use a cocoon frame with grids. After placing the mature silkworms on the cocoon frame, under physiological characteristics, the mature silkworms will crawl upwards. If the cocoon frame is not turned, all of them will be concentrated on the upper part of the cocoon frame Making cocoons will also cause cocoons to stick to each other. Manually flipping the grid cocoon frame is not only labor-intensive, but also difficult to control the angle of flipping. Not to mention time-consuming and labor-intensive, it will also bring unnecessary economic burden to silkworm farmers.
