中文摘要:喷肥针为扎穴机构的关键部件,作业时直接与土壤接触,其结构特点影响施肥质量。设计了一种新型的双斜孔式喷肥针,并对其进行了动力学分析。在搭建的动力学测试系统台架上以土槽车前进速度和行星架转速为试验因素,以土壤对喷肥针反作用力为指标,对喷肥针扎穴过程受到的土壤反作用力进行试验测定。试验结果表明,喷肥针受到的土壤拉压力随土槽车前进速度及行星架转速的增加而减小,变化范围为19.944~25.936N;弯曲力随土槽车前进速度及行星架转速的增加而增大,变化范围为8.62~75.32N,行星架转速对喷肥针反作用力的影响显著;根据试验结果,行星架转速在100~120r/min时,既可提高工作效率,又能保证扎穴机构的正常工作

Abstract:Spray fertilizer needle is the executive component of pricking hole mechanism, which is working on the soil directly, so its construction feature will affect the fertilization quality. In order to improve the operation quality, a new type spray fertilizer needle with double oblique hole was designed and its dynamics characters were studied. On the dynamics testing system bench, taking forward speed of soil tank vehicle and rotation speed of planet carrier as experimental factors, and the reaction of soil particles to spray fertilizer needle as indicator, the reaction force of soil particles to spray fertilizer needle during pricking hole was determined. Result shows that, the tensile stress of needle was decreased with the increasing forward speed and rotation speed, which was in the range of 19.944~25.936N. Bending force was increased with the increasing forward speed and rotation speed, which was in the range of 8.62~75.32N. The rotation speed has a significant effect on the reaction of spray fertilizer needle. According to the test results, the rotation speed of planet carrier with the range of 100~120r/min could improve the work efficiency and ensure normal work of pricking hole mechanism.

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.
