棉秆粉碎还田与残膜回收联合作业机研制与试验

针对新疆棉区秸秆粉碎还田与残膜回收机联合作业时出现的膜杆不分、残膜回收率低、脱膜效果差以及残膜易缠绕等问题,该文设计了棉秆粉碎还田与残膜回收联合作业机,主要由牵引装置、秸秆粉碎装置、秸秆输送装置、浮动式残膜回收装置、脱膜装置、传动系统、残膜回收箱、机架和地轮等组成,一次作业可实现棉秸秆粉碎还田、膜杆分离和残膜回收。该机将锤片式棉秸秆粉碎装置与刮板式输送装置相结合,用于秸秆粉碎还田和秸秆与待收残膜分离;采用浮动式起膜机构和齿耙式搂膜装置回收残膜,地面仿形效果好,有利于提高残膜回收率;用气力脱膜装置脱膜,提高脱膜可靠性,并防止残膜与收膜装置的缠绕而影响机具正常工作。通过对主要工作部件的设计,确定主...

Summary:针对新疆棉区秸秆粉碎还田与残膜回收机联合作业时出现的膜杆不分、残膜回收率低、脱膜效果差以及残膜易缠绕等问题,该文设计了棉秆粉碎还田与残膜回收联合作业机,主要由牵引装置、秸秆粉碎装置、秸秆输送装置、浮动式残膜回收装置、脱膜装置、传动系统、残膜回收箱、机架和地轮等组成,一次作业可实现棉秸秆粉碎还田、膜杆分离和残膜回收。该机将锤片式棉秸秆粉碎装置与刮板式输送装置相结合,用于秸秆粉碎还田和秸秆与待收残膜分离;采用浮动式起膜机构和齿耙式搂膜装置回收残膜,地面仿形效果好,有利于提高残膜回收率;用气力脱膜装置脱膜,提高脱膜可靠性,并防止残膜与收膜装置的缠绕而影响机具正常工作。通过对主要工作部件的设计,确定主要结构和工作参数,并分析了样机的工作过程。田间试验表明,在机具作业速度5~5.5km/h、秸秆输送链轮转速125r/min、输送装置倾角40°、残膜输送链轮转速70r/min和风机转速1620r/min时,能达到膜杆分离率97%,残膜回收率88.6%,脱膜率89.4%,能够满足秸秆粉碎还阳与残膜回收的技术要求,研究成果有利于解决棉田饯膜污染问题。

According to the problems of plastic film without distinction as straw, the plastic film recovery rate is low, the effect is poor in removing the collected film, and plastic films are easy to wind in cotton straw chopping and a plastic film collecting combined machine in Xinjiang province, the 4JM,1500 straw chopping and plastic film collecting machine has been designed. It consists of a traction device, straw chopping device, straw conveying device, floating gear-rake institution and chain rake device, film removing device, driven system, plastic film box, and rack and wheel, etc. It can realize straw chopper returning, the straw separation with plastic film, and the plastic film recycling with one operation. This machine combining the hammer device of cotton straw chopping and scraper conveyor
