Optimization design of sweet potato horizontal transplanting mechanism based on EDEM-ADAMS
Aiming at the problems that there are few existing sweet potato horizontal transplanting machines and the transplanting position does not meet the agronomic requirements,this paper designs a sweet potato transplanting mechanism that can realize flat planting by combining the agronomic needs of sweet potato planting.The overall structure and critical components of transplanting mechanism are optimized through establishing mathematical modelling.With the forward speed and installation height of the mechanism as the test factors,the simulation test and parameter optimization of the depth of potato seedlings into the soil and the straight length in the soil was carried out by coupled EDEM-ADAMS simulation.The optimal parameters of the simulation test were determined as the forward speed of the mechanism by 0.22 m/s and the installation height by 181 mm.The test results showed that the passing rate of the depth of potato seedlings into the soil and the straight length in the soil of sweet potato seedlings were 95.32%and 93.12%,respectively,which met the agronomic requirements of sweet potato horizontal planting.
