A silkworm chrysalis screening device

Abstract

The present invention relates to the field of silkworms, in particular to a screening device for silkworm chrysalis. The screening device includes a bracket, a bearing seat connected to the bracket, two shafts matched and connected to the bearing seats, and a pulley fixed on the shaft. , a belt, the two shafts are arranged parallel and side by side on the bracket, the shaft fixes the two shafts through the bearing seat, the pulley is fixed on the shaft, and the belt connects the two shafts The belt pulley on the shaft, the belt between the shafts forms a string shape, and the distance between the two belts gradually increases. The device can automatically sort male and female silkworm chrysalis in batches, with high efficiency and can save a lot of labor; the materials used in the device are some common materials in the market, which are cheap, cheap, low cost, and easy to promote; the device is simple and practical, easy to maintain convenient.

Description

technical field [0001] The invention relates to the field of silkworms, in particular to a silkworm chrysalis screening device. Background technique [0002] In the process of silkworm cocoon seed production, the male and female silkworm chrysalis must be sorted out first and separated. After the silkworm chrysalis basically turn into silkworm moths, the female silkworm moths and male silkworm moths are put together for mating. After mating, the male silkworm moths are taken away and kept The female silk moth lays eggs. [0003] Among the above-mentioned processes, a key process is to distinguish male and female silkworm chrysalis. At present, silkworm breeding farms use manual identification of chrysalis. The staff need to pick up the silkworm chrysalis one by one, put them in a place with strong light, and carefully check the tail of the silkworm chrysalis. If there is a pattern similar to "X" at the tail of the silkworm chrysalis, it is a female silkworm chrysalis. Simi...

Problems solved by technology

This manual sorting method can only sort one silkworm chrysalis per person at a time, and silkworm cocoon seed production is a short-term and heavy-duty job. Silkworm seed farms often need to hire a large number of temporary workers for sorting during this time period. silkworm chrysalis

Today, when a large number of urban population flows into cities to work, it is difficult to hire so many temporary workers, and the cost is also high.

Therefore, manual sorting of silkworm chrysalis is labor-intensive, low in production efficiency, and high in cost.
