弹齿式收膜机主要结构设计

Development of spring-tooth plastic film collecting machine

针对北方垄作制小根茬作物的田间收膜设计了弹齿式残膜回收机。介绍了该收膜机的结构组成、工作原理及主要工作部件的设计原则 ,给出了机具的作业性能指标。样机田间测试结果为 ,残膜收净率 91 6 % ,纯工作生产率 0 38hm2 ·h-1;机具结构简单、合理 ,工作可靠 ,性能参数达到设计要求。该机具配套动力 13 2kW ,既适用于70 0mm垄的收膜 ( 1次收双行 ) ,也适用于 10 0 0mm的大垄 ( 1次收 1行 ) ,通用性较好 ,具有广阔的推广应用前景。

The configuration compose, working principle and design principle on main working parts of spring tooth type plastic film collecting machine was introducted. The rate of collecting used plastic film was 91 6 % , and productivity was 0 38?hm 2·h -1 , the power that machine needed is 13 2?kW. The machine was the same with ridge note only 700?mm, but also 1?000?mm. The result indicated that the machine structure was simple and operation and maintenance was convenienxt.
