为了提高油用牡丹移栽质量，根据牡丹苗木特性和移栽效果，对油用牡丹移栽过程进行了分析。设计了一种牡丹幼苗移植机，主要由链夹式种植机构（夹具、传动链、链轮）、滑道、仿形轮、开沟器、动力传动系统和机架组成。通过对播种机构的运动分析和作业过程的分析，对其结构参数进行了优化。确定了夹持器的有效长度为L-1 =235 mm，调节范围为235-285 mm，栽植轨迹高度为H=340 mm。推杆的有效长度确定为L-2=420 cm，宽度T-2=105 mm，滑道之间的距离S=45 mm。推杆的初始角度差为θ =13度，推杆旋转角度β =37度，推杆高度比β =2。根据上述参数和设计要求，确定栽植链轮半径R-1 =42 mm，R-2=80 mm。以“枫丹”牡丹实生苗为移栽试验对象。结果表明：栽植频率为60-75株/min时，立苗率为89.2%~ 92.8%，漏苗率为0 ~ 0.28%，伤苗率为0，栽植深度合格率为91.7%~ 95.3%，株距变异系数为0.25%~ 0.54%。该机能有效提高移栽质量和效率，满足机械设计要求和生产需要。
In order to improve the quality of oil peony transplanting, based on the characteristics of peony seedlings and the transplanting effect, the transplanting process was analyzed. A peony seedling transplanting machine was designed, which was mainly composed of a chain-clamp type planting mechanism (clamp, transmission chain, sprocket), slideway, profiling wheels, trencher, the power transmission system and rack. Through the movement analysis of the planting mechanism and its operation process, its structural parameters were optimized. The effective length of the clamp was determined as L-1 =235 mm, the adjustment range was 235-285 mm, and the height of the planting trajectory was H=340 mm. Based on the physical characteristics and mechanical characteristics of the peony seedlings, the parameters of the slideway and the putter were determined. The effective length of the slideway was determined as L-2=420 cm, the width T-2=105 mm, the distance between the slideways S=45 mm. The initial angle difference of the putter was theta=13 degrees, and the putter rotation angle beta=37 degrees, putter height ratio epsilon=2. Based on the above parameters and design requirements, the radius of the planting sprocket R-1 =42 mm, R-2=80 mm. "Feng Dan" peony seedlings were used as transplantation test objects. The results showed that: when the planting frequency was 60-75 plants/min, the upright rate was 89.2%-92.8%, the leakage rate was 0-0.28%, the injury rate of seedlings was 0, and the qualified rate of planting depth was 91.7%-95.3%, the variation coefficient of plant spacing was 0.25%-0.54%. This machine can effectively improve the quality and efficiency of transplanting, meeting the requirements of mechanical design and production needs.
