Design and Testing of Parallel Four-bar Profiling Mechanism for the Small Transplanting Machine for Rapeseed Blanket Seedlings
摘要
Abstract
Aiming at the existing rapeseed blanket seedlings transplanter is mostly six-row transplanter with large size,which is not suitable for transplanting operation in hilly and mountainous areas with small plot,many slopes and complex terrain.Based on the two-row small-sized walking transplanter,a small-sized transplanter for rapeseed carpet seedlings was designed.Due to the poor flatness of hilly and mountainous areas,a parallelogram mechanism was designed to con-trol the planting depth under uneven soil conditions.Based on the actual transplanting environment and the structure of the existing transplanter,the profile length of the profile rod was designed to be 210 mm,the maximum upper and lower profile was 80 mm,and the upper and lower profile angle was 22°.The motion simulation was conducted with ADAMS software,the results showed that the profiled mechanism could control the planting depth under 5°,10° and 15° slopes.Compared with the original transplanter,the planting depth of the rape transplanter with the parallelogram profiled mecha-nism was more stable.The static analysis of the parallel four-bar copying mechanism with ANSYS software showed that the maximum stress was 91.646 MPa and the maximum strain was 0.76472 mm.The material strength of the copying mechanism could meet the maximum stress and strain requirements.The field test results showed that the optimized trans-planter had the following advantages:the miss rate was 2.50%,the qualified rate was 87.90%,the qualified rate was 88.62%,and the variation coefficient of planting depth was 11.22%,all of which were better than those before optimi-zation,and met the agronomic requirements of rapeseed blanket seedling transplanting.关键词
