摘要以前，传统的分离方法需要人工来识别不同的蚕蛹，这样会大大地增加成本，生产效率也不高，而且分辨的准确率也不高。因此一台能够自动识别雌雄蚕蛹并且分拣收集蚕蛹的机器将会解放人的双手，提高生产效率。85048

本文分析了中国国内雌雄蚕蛹分离机机的研究和发展现状，设计出了一种新型的雌雄蚕蛹分离机。该雌雄蚕蛹分离机是由分级滚筒、传动机构和电动机组成。采用电动机提供动力，通过带轮传动机构，将运动和动力传送到直齿圆柱齿轮减速器，然后再通过链轮传动机构，将所需的运动和动力传送至分级滚筒上，从而实现蚕蛹的分选。整个机构简单且易于操作，便于维护，为实现蚕蛹机械化与规模化提供了前提。

当这种机器普遍推广时，将会大大提高分辨雌雄蚕蛹的效率，提高生产效率，降低劳动强度，推动经济的发展。

Abstract In the past, the traditional separation method requires human to identify different silkworm chrysalis, this will greatly increase the cost, the production efficiency is not high also, and distinguish the accuracy is not high also。 Therefore one can automatically identify male and female silkworm chrysalis and sorting collection of silkworm chrysalis machine will liberate people's hands, improve production efficiency。

 This paper analyzes the present situation of the Chinese domestic and foreign silkworm chrysalis sorting machine research and development, on the future prospects, we design a new type of silkworm chrysalis sorting mechanism。 The silkworm chrysalis sorting machine is composed of grading cylinder, transmission mechanism and a motor。 The power provided by a motor, through a belt pulley transmission mechanism, the movement and power is transmitted to the straight tooth cylindrical gear reducer, and then through the chain wheel transmission mechanism, the required movement and power is transmitted to the classification on the drum, thereby we can realize the separation of silkworm chrysalis。 The entire mechanism is simple and easy to operate, easy to maintain, which help to achieve the silkworm chrysalis processing mechanization and scale and to provide the premise。

When the machine of the popularization, will greatly improve the efficiency of the distinguish between male and female silkworm chrysalis, improves the production efficiency, reduces the labor intensity, promote the development of the economy。

Key Words: silkworm chrysalis; shape; the grading mechanism; grading cylinder
