中文摘要:通过对D型打结器空间传动方案改进提出了双齿盘驱动打结器,将驱动夹绳器的空间传动布置在打结器支架的另一侧,将进口打结器支架一组空间交错轴角度关系简化为平面相交轴角度关系,降低了打结器支架的加工难度,克服了进口打结器空间交错轴锥齿轮齿廓设计与制造难的问题,便于批量化生产。通过将蜗杆与斜齿轮的传动比调整为1∶3使原四槽口夹绳盘改进为三槽口夹绳盘,并匹配设计了夹绳盘、打结嘴和刀臂的运动时序,建立了双齿盘驱动打结器的结构模型。与进口打结器的成结动作对比试验表明双齿盘驱动打结器的空间传动方案改进合理,驱动夹绳器、打结嘴和刀臂的运动时序匹配设计正确,夹绳和割绳动作比进口打结器更优,夹绳时捆绳直接入夹绳盘槽口,割绳时捆绳靠近刀片中间位置。室内台架的打结试验表明双齿盘驱动打结器的成结率为100%。

Abstract:By improving spatial transmission project of D knotter, a type of knotter driven by double gear-discs was presented. Spatial transmission of driving rope holder was arranged on another side of knotter stand. It simplifies a set of angle relation of spatial crossed axle on the imported knotter stand as angle relation of plane intersecting axle, reduces processing difficulty of the knotter stand, overcomes the difficult design and manufacture problem of spatial crossed bevel gear profile on the imported knotter, and is easy to be manufactured in large quantities. By adjusting the transmission ratio between worm and helical gear to 1∶3, original rope holding plate with four notches was changed into rope holding plate with three notches. The structure model of the knotter driven by double gear discs was built up after the motion sequences of driving rope holder, knotter jaw and knife arm were matched. The contrast test of knotting motion with the imported knotter shown that the improvement of spatial transmission project of the knotter driven by double gear discs is reasonable, moreover, the motion sequence matches design of rope holder, and knotter jaw and knife arm are right. The rope holding and rope cutting motions are even better than those of the imported knotter, and the rope is directly got into the notch of rope holding plate and cut off in the middle of the knife. The knotting tests operated on indoor bench showed that the knotting rate of the knotter driven by double gear discs may reach 100%. Further field tests of bundling straw will be executed to investigate the knotting rate and the reliability of knotter driven by double gear discs.

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.
