| 针对现有钵苗移栽机在起伏垄面作业时栽深控制稳定性低的问题，采用栽植器仿形方法，以可编程机床控制器（program machine control）为核心，设计了自动精准定深仿形装置以实现对每行栽植器独立主动仿形。通过理论分析确定自定深仿形装置关键结构与扭矩、升降速度等参数，并设计了自定深移栽试验台。运用正交试验优化方法，研究该仿形机构作业速度、升降速度和移栽株距参数变化与栽深合格率关系。通过Box-Benhnken组合试验，得到影响栽植深度合格率的各因素由大到小为移栽株距、升降速度、作业速度。通过软件寻优得到栽深合格率最高条件下的最佳参数组合为作业转速180 mm·s-1、升降速度142 mm·s-1、移栽株距195 mm。台架试验表明，采用自定深仿形装置后的平均栽深合格率为91.9%，具有田间实际应用价值。 |

| Aiming at solving the problem of low stability of planting depth control of existing transplanters in undulating ridge surface operation and realizing the independent active profiling for each row of planters, this paper uses the method of planter profiling to design an automatic precise depth determination and profiling device, which applied the program machine controller (PMC) as the core. Through theoretical analysis, the key structure and parameters, such as torque and lifting speed, the automatic depth setting and profiling device was determined, and a self\|setting depth transplanting test\|bed was designed. Using the orthogonal test optimization method, the relationship between the working speed, lifting speed, transplanting plant spacing parameters, and the qualified rate of planting depth was studied. Through the Box\|Benhnken combination test, the factors affecting the qualified rate of planting depth were transplanting plant distance > lifting speed > operation speed. The optimum parameter combination under the maximum qualified rate of planting depth was found under the combination of operating speed of 180 mm·s-1, lifting speed of 142 mm·s-1, and transplanting plant spacing of 195 mm·s-1. The bench test results showed that the average qualified rate of planting depth was 91.9% after using self\|setting depth profiling device, which was of practical application value in the field. |
