揭膜式残膜回收机的设计研究
|
摘要
针对目前新疆地区白色污染和二次污染严重、现有的残膜回收机拾净率低及残膜无法回收利用等问题,从改变地膜厚度入手,设计出了一种新型的揭膜式残膜回收机。该机型采用对辊挤压原理,将传统的搂膜扎膜等收集残膜的方式转变为揭膜卷膜,从而保证了机器工作过程中的稳定性和收膜过程的连续性。同时,对其关键装置进行了参数设计和运动学分析,并进行了田间试验。结果表明:该机型残膜拾净率高达96.8%,对土壤环境的保护有显著效果。
In order to solve the serious problem such as white pollution,secondary pollution in Xinjiang region,the low recovery rate of existing residual film recycling machine and residual film unable to recycling,from changing the thickness of the membrane,design a new shoveling type plastic film recycling machine. The roll extrusion principle is used to this machine,changing the traditional way of collecting film such as hugging and pricking film into the way of shoveling and rolling film,thus ensure the process of machine work stability and continuity. In this paper,the parameter design and kinematics analysis of the key devices are carried out. The experiment results show that the recovery rate is as high as 96. 8% and the machine has a significant effect on protecting soil environment.
