中文摘要:机具的清茬效率是秸秆覆盖条件下免耕播种的重要指标。针对东北地区保护性耕作模式,在吉林省康达农业机械有限公司生产的2BMZF-2型免耕播种机上,改进设计一种具有凹面结构的秸秆清茬机构,分析了播种机作业速度、清茬轮入土深度以及清茬轮运动偏角等因素对清茬效果的影响。根据仿真分析以及田间试验结果确定了清茬机构的关键参数,以及最佳工作参数组合为:清茬轮轮盘直径D为350mm、运动偏角λ为37.5°、机具速度v0为2.77m/s、入土深度d为70mm。在上述参数条件下进行田间试验时,清茬率可达到83.61%。结果表明,所设计的清茬机构可有效清洁种床、减少机具堵塞,可以为东北地区玉米免耕播种作业提供技术支撑。

Abstract:The stubble clearance efficiency of instrument is an important indicator of no tillage seeding under the mode of protective farming mode. Based on the conservation tillage model in Northeast China, a straw cleaning mechanism with concave structure was designed and improved on the 2BMZF-2 no till planter produced by Jilin Kangda Agricultural Machinery Co., Ltd. In addition, factors such as the operating speed of planter in the stubble clearance mechanism, the soil contacting depth of stubble clearance wheel and the movement declination angle of stubble clearance wheel were analyzed. The key parameters of stubble clearance mechanism were identified according to the simulation analysis and the analysis on the results of field trial, which can be listed as follows: the diameter of stubble clearance wheel disc was 350mm, the angle between the movement direction of the stubble clearance wheel and the working direction of no tillage planter was 37.5°, and the soil contacting depth was 70mm. The result of the experiment indicated that the stubble clearance rate could reach up to as high as 8361% at the operating speed of 2.77m/s. The stubble clearance mechanism designed could effectively clean the seedbed and prevent the blocking of instrument, which, in the meantime, was suitable for the uniform ridge farming mode of maize as well as the wide and narrow row farming mode of maize.

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.
