摘　　要：针对移栽机械在黏重土壤条件下栽植辣椒作业时,栽植器表面粘土严重影响移栽机作业质量和效率的问题,基于凸包形非光滑表面减粘降阻机理,研发了一种适于黏重土壤条件的仿生栽植器。首先,通过EDEM软件完成栽植器打穴仿真分析,发现仿生栽植器在整个打穴过程中所受应力低于普通栽植器所受的应力,有一定的降阻作用;然后,将仿生栽植器与普通栽植器分别在含水率为18.34%、22.31%、29.55%,栽植频率为30、50、70株·min^(-1)条件下进行田间对比试验,结果表明:较普通栽植器而言,仿生栽植器减粘效果较好,减粘率最高达到57.71%,最低达21.89%,说明仿生栽植器基本可用于黏重土壤条件辣椒移栽作业。研究结果可为黏重土壤条件下仿生触土部件的减粘降阻设计提供参考。in order to solve the problem that the clay on the surface of the transplanter seriously affects the quality and efficiency of the transplanter when planting hot pepper under the condition of heavy soil,a bionic planter suitable for the condition of heavy clay soil was developed based on the mechanism of reducing the viscosity and resistance of the convex hull non smooth surface.Firstly,edem software is used to complete the simulation analysis of the planting device.The simulation results show that the stress of the bionic planter is lower than that of the common planter in the whole process of drilling,which has a certain effect of reducing resistance.Then,the bionic planter was compared with the common planter in the field under the conditions of moisture content of 18.34%,22.31%and 29.55%,and the planting frequency of 30 seeds per minute,50 seeds per minute and 70 seeds per minute respectively.The results showed that the bionic planter had better viscosity reduction effect than the ordinary planter,with the highest viscosity reduction rate of 57.71%and the lowest of 21.89%It can be used for transplanting pepper in heavy soil.The results of this study can provide a reference for the design of bionic soil contact parts in viscous soil.
