中文摘要:目前残膜回收作业需要根据实际状况人为地对其破土深度和收膜速度进行反复停车调节,为了提高残膜回收作业的智能化水平和工作效率,对自主研制的弹齿式残膜回收装置进行改进,利用BECKHOFF CX2030控制器及模块和EtherCAT总线接口与GPRS联网,以实现起膜铲自动升降调节、卷膜齿转速在线检测、残膜回收在线视觉反馈和数据传输与监控等功能。通过对智能起膜铲的结构设计、理论分析和试验验证,得到了铲刀的安全倾角为65°~75°,适宜破土深度为20~50mm。智能残膜回收装置的田间试验表明,该装置在机械化回收作业方面是可行的,智能起膜铲的抗扭矩能力、残膜回收率、卸膜率和整机工作效率均表现良好。

Abstract:At present, the residual film recovery device needs to stop artificially and adjust repeatedly for its ground breaking depth and rolling speed based on actual situation during the work. It often leads to low levels of mechanization and efficiency. In order to improve intelligence and efficiency of the plastic film recovery unit, the subject takes the elastic tooth residual film recovery device of existing independently developed as the research object. BECKHOFF CX2030 controller and the module were used to collect the data of each sensor in real time and control the operation of the servo motor. Then through the Ethernet interface which based on EtherCAT bus and the GPRS network, it can realize the film shovel automatic lifting adjustment, the film cutting speed online detection, the residual film recovery online visual feedback, the data transmission and monitoring. Through the structure design, theoretical analysis and experimental verification of the intelligent film shovel, the inclination angle of the blade was obtained as 65° to 75°, the safety ground breaking depth was 20mm to 50mm. The application of image technology and computer simulation software was conducive to the real time feedback of residual film legacy and scientific calculation of residual film recovery rate and operating efficiency. The field experiment in sandy loam soil of potato ridge using the intelligent residual film recovery device based on EtherCAT & GPRS showed that, the effect of the residual film recovery operations was significant in the intelligent level and residual film recovery rate, and the overall level of the device was greatly improved. The successful research and development of the device will greatly promote the residual film recovery to multifunction, intelligence, digitization and automation.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
