鸡舍刮板式清粪机械设计
一、引言
目前，鸡畜在国内的大规模养殖越来越普遍，众多养殖场也在逐步走向机械化。然而，粪便清扫重复的大工作量，是养殖场必须重点解决的问题之一，为了减少人力参与，提高清扫效率，需要设计开发粪便清扫机械。现今，国内对于不同的养殖业已研究出众多不同的清粪机械，而最具代表性且经济实用当属刮板式清粪机。我们下面仅针对普遍适用于养鸡场的小型清粪机的的结构设计、工作原理和特点、主要零部件设计做下简单的研究探讨。
二、刮板式清粪机的设计
清粪机械在机械化养鸡生产中占有十分重要的地位。因为机械清粪不仅可以大大地减轻劳动强度，使室内保持良好的空气环境，减少疾病的发生率，而且还能有效地影响鸡的生产，增加经济效益，所以欲要搞好机械化养鸡，就必须有性能优良的刮粪机械系统，这是至关重要的一个问题。在众多的清粪机械中，刮粪板这种方式简单而易行。刮板式清粪机主要应用于笼养鸡舍中。机械组成主要有电动机、减速器、刮板、钢丝绳与转向开关等设备。
1、刮板式清粪机的优点
（1）利用刮板式清粪机，可以大幅度的解决人工粪便清扫过程
3
中耗水量大问题，达到高效健康环保的养殖效益。
（2）通过刮板式清粪机，可以实现养鸡过程中粪便清扫的机械化及自动化，提高清扫的效率，减少人力参与，减轻人的劳动强度
（3）使用刮板式清粪机，可以保证养殖场所的长期卫生，实现鸡畜健康洁净养殖，减少鸡畜疾病的发生。
2、刮板式清粪机的工作原理
如图一所示，该刮板式清粪机工作时，电动机正转，驱动绞盘，便带动牵引绳正向运动，拉动刮板开始工作行程，开始清扫粪便工作。刮板正向运动过程中清扫粪便，并将粪便刮进横向粪沟，当刮板运行至终点，出动行程倒顺开关使电动机反转，带动牵引绳反向运动，拉动刮板进行空行程返回，到终点电动机又继续正转，同时，另一刮板也在进行反向清粪工作，如此循环往复两次就能达到预期清扫效果。
