中文摘要:为了减小深松耕作阻力、提高深松深度的稳定性,设计了一种入土角可控的自激式振动深松整地机。通过室内土槽对比试验优化了自激式振动深松装置的弹簧参数,验证了减阻效果,并对整机作业质量进行了田间测试。土槽试验表明:弹簧的性能参数对减阻效果有显著影响,当弹簧刚度为194N/mm时,入土角可控自激振动深松可使牵引阻力下降29.8%,自激振动条件下入土角可控较不可控牵引阻力下降8.9%;田间试验结果表明:深松整地机作业后深松深度合格率达到100%,稳定性系数达到95.49%,土壤膨松度平均值为19.34%,土壤干扰系数为56.62%;机具作业后地表平整,碎土率平均值为76.4%,通过性能良好,较好地满足了我国北方一年两熟区深松整地技术的要求。

Abstract:To reduce operating resistance and improve the stability of deep loosening,a self exciting vibration deep loosening and sub soiling machine with controllable cutting angle was designed. The range of the cutting angle was controlled in 19°~25°. To optimize parameters of elastic component and validate the effect of drag reduction,the experiment in the soil bin was carried out, furthermore, the field experiment of operation quality and performance of the machine was conducted. The experiment in soil bin showed that the parameter of elastic significantly affected the resistance reduction, when the stiffness of the elastic was 194 N/mm, the traction resistance can be reduced about 29.8%. Also the effect of elastic component parameters on the drag reduction was significant, and under the condition of self exciting vibration, with controllable penetration angle, the traction resistance was decreased by 8.9% than that with uncontrollable penetration angle. The results of the field experiments showed that the qualified rate of sub soiling depth was 100%, stability coefficient reached 95.49%, the average of soil fluffy and soil disturbance coefficient were 19.34% and 56.62% respectively, the land surface was flat after sub soiling, and the average of the soil crushing rate was 76.4%. Moreover, the trafficability in the period of the test was good, and the machine met the subsoiling technical requirements in double cropping area in northwest China.

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.
