中文摘要:针对三插臂分插机构理论分析不全面和增加插植臂数量导致株距适应范围缩小等问题,提出了一种椭圆齿轮非匀速三插臂分插机构,建立了该分插机构的运动学分析模型,研究了分插机构回转箱体非匀速转动对栽插参数的影响,理论分析得出非匀速转动不影响秧针的静态轨迹、取秧角度、推秧角度和轨迹高度,传动系统中椭圆齿轮偏心率和初始相位角对秧针取秧点 y 方向的速度影响最大,相位角为0°时,取秧点 y 方向线速度达到最大。插秧穴口随着偏心率增大而增大,初始相位角对插秧穴口的影响较复杂,在0°~90°范围内随相位角增大而增大,在90°~180°范围内随相位角增大而减小。在室内进行了插植臂速度和移箱回数对伤秧率和切块均匀性的影响试验,试验表明伤秧率随分插机构转速增加而增大且影响显著,但移箱回数差异对伤秧率影响不显著。移箱回数差异对切块均匀性的影响显著,移箱回数18回的切块均匀性明显高于对照组,在移箱回数21回和24回时切块均匀性与对照二插臂的切块均匀性差异不大,分插机构转速增加对秧苗切块均匀性有影响但影响不显著。田间对比试验表明,非匀速三插臂分插机构栽植质量优于对照组,伤秧率均随作业速度的提高而增大,翻倒率和漂秧率也随作业速度的增加而增加但影响不显著,作业速度变化对漏插率影响也不显著

Abstract:For no full analysis on the theories of three planting bars of transplanting mechanism and reducing the row spacing applicable range by increasing the quantity of planting bars, a non-uniform rotation three planting bars of transplanting mechanism was proposed. The kinematics analysis model was built based on its working principle, and the effects of transplanting parameters on non-uniform rotational speed were studied. The theoretical analysis was received that the non-uniform rotational speed had no effects on the static trajectory of planting hoe, taking seedling angle, pushing seedling angle and trajectory height. Eccentricity ratio and initial phase angle of the elliptic gears had great effects on the velocity with axis y at the point of taking seedling, the speed of taking seedling points with axis y reached the largest when the phase angle was 0°. The transplanting hole was increased with the increase of eccentricity ratio, the initial phase angle had relatively complex effects on the transplanting hole, which would get large with the increase of initial phase angle between 0°~90°, and get small with the increase of initial phase angle between 90°~180°. The effects of speed of transplanting bars and the movement times of seedling box on the damaged seedling rate and stripping-slicing homogeneities were tested in laboratory, the results indicated that the damaged seedling ratio was increased with the increase of revolving speed and the impact was significant, but the movement times had no significant impact on it. The movement times had significant impact on the stripping-slicing homogeneity, which was significantly higher than the matched group when the movement times was 18, the difference between the stripping-slicing homogeneities when the movement times equaled to 21 and 24 and the two contrast transplanting bars was little, but the revolving speed had effect on it and the impact was non-significant. Field contrast test indicated that the planting quality of the non-uniform rotation three planting bars was superior to that of the matched group, the damaged seedling rate was increased with the increase of work speed, the laid seedling hill rate and the floating seedling rate were also increased with the increase of work speed, but the impacts were non-significant, and the work speed had no effect on the missing planting hill rate.

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.
