Method and special device for separating fly maggots from substrates

Abstract

The invention relates to the field of fly maggot feeding devices and methods, in particular to a method and a special device for separating fly maggots from substrates. The special device for separating the fly maggots from the substrates comprises a crude substrate separator and a fine substrate separator, wherein the crude substrate separator comprises a crude substrate separation net, a rack, a rotary shaft and a power drive mechanism, the crude substrate separation net is of a cylinder structure, the rotary shaft is arranged on the rack and is in transmission connection with the power drive mechanism, and the rotary shaft passes through the interior of the crude substrate separation net to be connected with the crude substrate separation net through a connecting rod; the size of each mesh of the fine substrate separation net is smaller than the length of a straightened fly maggot. According to the method and the special device for separating the fly maggots from the substrates, fly maggots are in a straightening state when turning over in the separation net, so that the lengths of the fly maggots are basically consistent; that substrates of larger grains and substrates of smaller grains are completely separated through different sizes of the meshes of the separation nets is ensured, so that the integral separation is more complete, and the separation rate is high.

Description

technical field [0001] The invention relates to the field of fly maggot breeding equipment and methods, in particular to a special equipment and separation method for separating fly maggots and substrates. Background technique [0002] In the existing fly maggot breeding process, after the fly maggots grow and mature inside the matrix, the fly maggots need to be separated from the matrix. , so that the fly maggots drill into the matrix, the staff strips the surface matrix, and repeats many times to separate most of the matrix, but the cleanliness of the separation is poor, the workload is large, and the efficiency is low. However, in the existing process of screening the matrix by using a plane sieve, the fly maggots are difficult to be separated accurately due to the inconsistent stretching degree of the fly maggots. Some fly maggots are mixed in the small matrix, and some fly maggots are mixed in the thicker Inside the matrix, the separation is poor. Contents of the inv...
