针对机收集条残膜质地松散、占用空间大、储运成本高等问题,设计一种适用于残膜打包作业的压包成型系统。通过残膜压缩特性试验与松弛试验获得残膜压包成型最优作业压强为7 MPa,据此完成液压元件优选计算,并设计了双泵加载液压系统。为实现集条残膜自动压包成型,开发了基于PLC的残膜压包控制系统,规划了动作控制软件流程。在新疆兵团第六师共青团进行残膜压包成型田间试验,结果表明,集条残膜打包机作业效果良好,残膜压包成型成功率达88%,成型时间为38.6s,满足田间作业要求。
Aiming at the problem of loose texture, large occupied space and high cost of storage and transportation of machine collecting bars, a compression molding system suitable for the residual film packing operation was designed. Through the residual film compression test and relaxation test, the optimum working pressure of blank film compression molding is 7 MPa. Based on this, the optimal calculation of hydraulic components and the design of double pump hydraulic system are designed. In order to realize the automatic film forming of the residual film, a PLC-based residual film compression control system was developed and the flow of motion control software was planned. In the Xinjiang Corps sixth division of the Communist Youth League for film compression molding field trials, the results show that the set of residual film balers operating good results, the residual film compression molding success rate of 88%, molding time was 38.6s, to meet field requirements .
