Simulation Analysis And Performance Experiment Of Dibble-type Transplanting Device Based On Slip Rate

2ZB-2 dibble-type transplanter is a kind of semi automatic transplanting machine,which can realize the transplanting on the membrane.The core part is the transplanting mechanism which is composed of dibble-type transplanting device,a mounting plate and a control panel.In the process of transplanting,due to the different physical properties of the soil,the ground wheel will slide,which will affect the trajectory of the dibble-type transplanting device and affect the quality of seedling planting.This paper establishes a three-dimensional model of transplanting device by Pro/E software,and conduct the motion simulation of transplanting device by Adams software,obtained the trajectory curve and the movement characteristic coefficient values of dibble-type transplanting device under different slip rate and transmission ratio.Analyzes the relationship between plant spacing and the hole length on the film with slip rate change.Field experiments were carried out under different soil hardness and different transmission ratio.The experiment showed that with the increase of soil hardness,slip rate of transplanting machine decreases,and decreases with the slip rate,the same transmission ratio when the movement characteristic coefficient values increases.The average soil hardness from 234.24 N/cm2 to 264.71 N/cm2 slip rate change range is smaller.The maximum error of simulation and experiment of the hole length is 24.77%,the maximum error of simulation and experiment of plant spacing value is 7.75%.The results show that when the movement characteristic coefficient values are in the range of 1.038 to 1.186,the film size is the smallest.
