中文摘要:针对镇压作业时,土壤粘附严重、牵引阻力大等问题,借鉴地面机械触土部件减粘降阻法,设计了一种机械式减粘降阻镇压装置。进行镇压装置运动过程分析、镇压轮表面脱土机理分析和刮削板脱土机理分析,为确定镇压装置减粘降阻的能力提供了理论依据,并在此基础上对镇压装置的关键机构进行了设计。为研究机械式减粘降阻镇压装置的工作性能,以弹簧刚度、前进速度和刮削角为试验因素,以牵引阻力、土壤粘附量为试验指标,在室内土槽中进行L9(34)正交试验。试验结果表明:各因素对指标影响的主次顺序为弹簧刚度、刮削角、前进速度;最优水平组合为弹簧刚度40N/mm、刮削角30°、前进速度7km/h。以最优水平组合进行验证试验,得到牵引阻力39.6N,土壤粘附量43.24g。与传统镇压装置的对比试验表明,机械式减粘降阻镇压装置使牵引阻力降低17.8%,土壤粘附量降低34.8%。

Abstract:Aiming at the problems such as serious soil adhesion, large traction resistance, a press device in mechanical type reducing adhesion and resistance was designed according to the method of terrain machines reducing adhesion and resistance. The movement process of press device was analyzed. The suppression device, scraping angle to take off the soil, and soil compaction mechanism analysis were done. The mechanism analysis can provide theoretical basis for the design of the press device, and based on that the key components of press device was designed. For the study performance of press device in mechanical type reducing adhesion and resistance, the spring stiffness coefficient, speed and scraping angle were taken as experimental factors, traction resistance, soil adhesive quality were taken as test indexes. The orthogonal test L9(34) was conducted in the indoor soil bin for getting test factors affecting the performance of press device work. Test results showed that the order of the various factors affecting were as follows: the spring stiffness coefficient, scraping angle and speed;the best combination: the spring stiffness coefficient was 40N/mm, scraping angle was 30°, and speed was 7km/h. To the optimal level combination of verification experiment: traction resistance was 39.6N, and soil adhesive quality was 43.24g. Compared with the traditional repressive device, the results showed that the press device based on scrape and vibration principle can reduce the traction resistance by 17.8% and the soil adhesion can be reduced by 34.8%.

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.
