Example Embodiment

[0016] Example 1:

[0017] Such as figure 1 , figure 2 As shown, the special equipment for separation of fly maggots and substrates described in this embodiment includes a coarse substrate separation device and a fine substrate separation device. The coarse substrate separation device includes a coarse substrate separation net 6, a frame 1, a rotating shaft 2, and a power drive mechanism. The coarse matrix separation net 6 has a cylindrical structure. The rotating shaft 2 is arranged on the frame 1 and is connected to the power driving mechanism. The rotating shaft 2 passes through the coarse matrix separation net 6 and is connected to the coarse matrix separation net 6 through the connecting rod 8. The coarse matrix separation net 6 is provided with a material inlet 3 at one end, and a material outlet 4 at the other end. The mesh size of the coarse matrix separation net 6 is larger than the length of the fly maggots after being stretched; the fine matrix separation device inclu...

Example Embodiment

[0020] Example 3:

[0021] In the method for separating fly maggots and substrates described in this embodiment, the mixture of fly maggots and substrates is first fed into the coarse substrate separation net 6 through the material inlet 3, and as the coarse substrate separation net 6 rotates, the fine substrates and fly maggots can be separated It is filtered and dropped from the holes of the coarse substrate separation net 6, and the coarse substrate of large particles is discharged from the material outlet 4. Secondly, the fine substrate and fly maggots filtered from the coarse substrate separation net 6 are fed into the fine material from the material inlet 3. In the matrix separation net 7, during the rotation of the fine matrix separation net 7, the fly maggots are in a stretched state, the fine matrix is ​​filtered out from the fine matrix separation net 7, and the fly maggots are in the fine matrix separation net 7, and the material Exit 4 is discharged.

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...
