中文摘要:东北垄作区播种前的根茬处理及深松作业,能够提高播种质量,促进作物生长。针对现有深松灭茬机作业过程中存在动土量大、灭茬效果不理想以及刀辊易缠草堵塞等问题,同时为适应东北寒地保护性耕作技术模式,满足垄体深松灭茬的农艺要求,设计了一种带状深松灭茬机,并对其灭茬部件、深松部件及垄台成形部件结构进行了设计。以机具的作业速度、灭茬深度和灭茬刀正切刃滑切角为试验因素,以灭茬率、灭茬深度稳定性系数为试验指标,对影响整机性能的结构与作业参数进行田间试验。结果表明:机器的作业速度为2.8km/h、灭茬深度为84.9mm、正切刃滑切角为6.5°时,灭茬率为93.26%,灭茬深度稳定性系数为95.25%,灭茬效果好,满足机具作业质量要求。

Abstract:In the northeast ridge area,the stubble treatment and subsoiling operation before planting can improve the quality of seeding and promote the growth of crop. In the process of operation,available machines for subsoiling and stubble-breaking exist some problems,including the large amount of soil disturbance,the not ideal effect of stubble cleaning and stubble-breaking roller is easy to tangle with grass etc. At the same time,in order to adapt to the technology mode of conservation tillage in the northeast cold,and meet the agronomic requirements of ridge deep loosening stubble, a type of subsoiling and stubble-breaking machine was designed, of which the structure of stubble-breaking parts,subsoiling component and ridge forming parts were designed. Also,the field experiments were carried out to study the structure and operating parameters affected the machine. The influence factors of field experiment included the speed of working machine,the depth of stubble-breaking and the sliding cutting angle of sidelong edge for stubble-breaking blade. Evaluation indices included the rate of stubble-breaking and the depth stability coefficient of stubble breaking. The results showed that when the speed of working was 2.8km/h,the depth of stubble-breaking was 84.9mm,the sliding cutting angle of sidelong edge for stubble-breaking blade was 6.5°,the rate of stubble-breaking was 93.26%,the depth stability coefficient of stubble breaking was 95.25%. The stubble-breaking effect of stubble-breaking machine was ideal,which met the quality requirements in working.

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.
