| 针对现有烟草移栽机存在的栽植深度不足和撕膜等问题，设计了一种曲柄多杆机构，通过建立数学模型获得栽植点轨迹方程，进一步通过试验确定影响轨迹的主要因素。杆件参数中无交互作用影响的通过单因素试验确定取值，有交互作用的以杆件长度、位置及角度为变量，轨迹出入土横向位移和栽植直立度为评价指标，在作业速度为375 mm·s-1、栽植速度为50株·min-1时，得到一组较优参数组合：L1=49.95 mm、L2=240 mm、L3=140 mm、L6=40 mm、L7=250 mm、L8=280 mm、L10=200 mm、L14=250 mm、Ψ=3.26°、m=90、n=100。在此条件下，株距、栽植深度、横向位移分别为450、150、14.06 mm，田间试验进一步表明株距变异系数小于6%、平均撕膜长度均小于120 mm、平均栽植深度均为144.7 mm，满足烟草移栽农艺要求，为移栽机结构和性能参数进一步优化提供了理论和技术支撑。 |

| In view of the problems of insufficient planting depth and tearing film in the existing tobacco transplanting machine, a crank multi\|rod mechanism was proposed, and the trajectory equation of the planting point was obtained by establishing a mathematical model, and the main factors affecting the trajectory were further determined through experiments. The parameters of the rod without interaction were determined by a single\|factor test. The length, position, and angle of the rod with interaction were taken as variables, and the lateral displacement of the track and the vertical degree of planting were taken as evaluation indexes. When the operating speed was 375 mm·s-1 and the planting speed was 50 times·min-1, a set of optimal parameter combinations was obtained: L1=49.95 mm, L2=240 mm, L3=140 mm, L6=40 mm, L7=250 mm, L8=280 mm, L10=200 mm, L14=250 mm, Ψ=3.26°, m=90, and n=100. Under these conditions, the plant spacing, planting depth, and lateral displacement were 450, 150, and 14.06 mm, respectively, and further field experiments showed that the coefficient of variation of plant spacing was less than 6%, the average tearing length was less than 120 mm, and the average planting depth was 144.7 mm, which met the agronomic requirements of tobacco transplanting and provided theoretical and technical support for the further optimization of the structure and performance parameters of the transplanting machine. |
