Problems solved by technology

[0003] The present invention solves the problem that in the current process of raising fly maggots in the laboratory, after the fly maggots pupate, the feed is separated from the fly pupae by washing the pupae, resulting in a decrease in work efficiency, and some fly pupae are drowned in water, which reduces the eclosion rate of fly pupae. problem, and then propose an automatic separation device for fly maggot pupation

Abstract

The invention relates to a separation device, in particular to an automatic fly larva pupating separation device. The problems of reducing the working efficiency, drowning a part of fly larvae in water and reducing the fly pupa emergence rate by separating feed from fly larvae in a pupa washing manner after pupating fly larvae in the current fly larva feeding process in a laboratory are solved. The device disclosed by the invention comprises an outer cylinder and further comprises an inner cylinder and a cylinder cover assembly. An outward extension converse V-shaped edge is arranged at the opening edge of the inner cylinder. The inner cylinder is arranged in the outer cylinder. The cylinder cover assembly is arranged at the opening of the outer cylinder in a buckling manner. The device disclosed by the invention is used for feeding fly larvae in the laboratory and automatically separating fly larvae from feed.

Description

technical field [0001] The invention relates to a separation device, in particular to an automatic separation device for fly maggot pupation. Background technique [0002] Fly maggots, that is, fly larvae, feed on organic matter such as livestock manure, wheat bran, various rotten bellflowers, vegetable leaves, bean cakes, etc., and grow and reproduce extremely fast. Fly maggot protein is high-quality white, not only high-quality feed, but also extract protein powder, develop advanced nutrition, aerospace food, medicine, etc. At present, fly maggots are raised in the laboratory by mixing fly maggots and feed into a breeding tank, and separating the feed from fly pupae after the fly maggots pupate. However, it is difficult to separate the fly pupae and feed after the fly maggots pupate. The separation method is to wash the pupae, that is, put the fly pupae and the feed into the water, and separate the fly pupae and the feed through the difference in the density of the fly pu...
