中文摘要:针对西北黄土高原旱区地膜全域覆盖、种行覆土垄播马铃薯机械化收获易堵塞、分离效果差、可靠性低、残膜污染等问题,设计了残膜回收型全膜覆土垄播马铃薯挖掘机,一次性完成排堵挖掘、薯土分离、薯膜分离、集薯铺条、膜秧分离和残膜回收等工序。通过理论分析和数值仿真,对仿生挖掘装置、曲柄摇杆防堵机构、薯土分离装置、薯膜分离装置、膜秧分离及残膜回收装置等关键部件进行解析和结构优化,确定了性能参数。田间试验表明:明薯率为97.4%,伤薯率为1.3%,破皮率为1.8%,残膜回收率为87.5%,生产率为0.17hm2/h,各项指标均满足国家及行业标准要求。

Abstract:In recent years, furrow ridge potato cultivation with global plastic film mulching technology is widely used in the semi arid areas of the Loess Plateau, this kind of cultivation mode is favorable for mechanical planting, but the difficulty of machine harvest is increased. In order to solve the problems of blockage in the process of digging, poor separation effect, low reliability and white pollution for the complete film mulching, planting line covering and ridge sowing pattern in the dry land of northwestern Chinese Loess Plateau, a potato digger with waste film recollection was designed, which can complete the anti blocking digging, potato separating from soil and film, potato collection and striping, disconnecting the film away from the residue seedlings and the waste film recollection in one process. By theoretical analysis and numerical simulation, the crucial parts, such as bionic digging device, anti blocking crank rocker mechanism, potato and soil separation device, potato and film partition device, residue seedlings and film disconnection device, the waste film recollection components as well as others were analyzed and optimized, and then the performance parameters were determined. Field experiments showed that the potato exposure rate was 97.4%, the potato injury rate was 1.3%, the potato skin damage was 1.8%, the waste film recollection rate was 87.5%, and the productivity can get to 0.17hm2/h, all the index of the potato digger with waste film recollection satisfied the requirements of national and industry standards, the problems such as the mulched potato harvesting and the waste film recollection were solved at the same time.

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.
