夹指链式残膜回收装置仿形及收膜机构的改进设计与试验

针对现有夹指链式残膜回收装置收膜作业地面仿形性差、作业性能不稳定的问题,设计了一种单铰接仿形及收膜机构,该机构主要由仿形机构和收膜机构两部分组成,整个收膜装置由多个单铰接仿形及收膜机构并排组成,每个单铰接仿形及收膜机构作业时可以单独仿形。仿形机构主要由仿形架、切膜圆盘、仿形轮、压紧机构和刮土板组成,切膜圆盘固连在仿形轮一侧,将地表残膜切成带状的同时对地表进行仿形,压紧弹簧产生的预压力使仿形机构始终紧贴地表仿形,通过对仿形机构的设计,确定了其结构尺寸参数,并对该装置的上仿形运动和下仿形运动进行了分析与讨论。田间试验表明,在机具作业5.5 km/h、切膜圆盘直径为280 mm、仿形轮直径为220...

Summary:针对现有夹指链式残膜回收装置收膜作业地面仿形性差、作业性能不稳定的问题,设计了一种单铰接仿形及收膜机构,该机构主要由仿形机构和收膜机构两部分组成,整个收膜装置由多个单铰接仿形及收膜机构并排组成,每个单铰接仿形及收膜机构作业时可以单独仿形。仿形机构主要由仿形架、切膜圆盘、仿形轮、压紧机构和刮土板组成,切膜圆盘固连在仿形轮一侧,将地表残膜切成带状的同时对地表进行仿形,压紧弹簧产生的预压力使仿形机构始终紧贴地表仿形,通过对仿形机构的设计,确定了其结构尺寸参数,并对该装置的上仿形运动和下仿形运动进行了分析与讨论。田间试验表明,在机具作业5.5 km/h、切膜圆盘直径为280 mm、仿形轮直径为220 mm时,残膜回收率达93.1%,能够满足残膜回收技术要求,研究成果有利于解决残膜污染问题。
Bibliography:The existing clamping finger-chain type device of recycling plastic film has the problem of poor profiling quality of film collecting operation and instable work performance, so the profiling and recycling plastic film mechanism with single hinge has been designed. The designed device is mainly composed of 2 parts which are profiling mechanism and film collecting mechanism. Whole film collecting device consists of multiple mechanisms of profiling and recycling plastic film mechanism with single hinge. And profiling can be separately performed when each profiling and recycling plastic film mechanism with single hinge is operating. The profiling mechanism is mainly composed of the profiling frame, the film cutting disc, the profiling wheel, compression mechanism and scraping plate, and so on. The role of the scraping plate is to scrape the soil on the profiling wheel, in order to avoid too much clay on the profiling wheel and the increase in size, which result in insufficient finger insertion depth.
