Cam-driven Seedling Picking and Placing Transmission Mechanism of Vegetable Transplanters Based on Reverse Motion Law
摘要
Abstract
Aiming to further enhance the stability and efficiency of the vegetable transplanting machine's seedling picking and placing process,a double cam and link-type seedling picking and placing transmission mechanism was designed for the clamping type seedling picking and placing method.Based on the displacement requirements,the structure was designed.By using the reverse motion law method,the motion law of the input end rocker was determined by reversing the ideal motion law of the output end,and then the cam profile corresponding to the high-demand and large-stroke horizontal seedling feeding section was determined.The motion process of the mechanism was simulated and analyzed by ADAMS,and the results were compared with the theoretical results to verify the correctness and feasibility of the design.A seedling picking and placing test bench was built,and pepper pot seedlings were selected as the test objects.The seedling age,picking speed and substrate moisture content were selected as the test factors,and single-factor tests were designed with the picking success rate,placing success rate and pot body damage rate as the evaluation indicators.The Box-Behnken response surface analysis method was used to design orthogonal tests,the interaction effects of the test factors on the seedling picking and placing effect were obtained,and the optimized picking parameters were obtained.Verification tests were carried out,and the experimental results showed that when the seedling age was 50 days,the picking speed was 56 plants/min,and the substrate moisture content was 52％,the picking success rate was 97.58％,the placing success rate was 95.64％,and the pot body damage rate was 5.32％,which met the technical requirements of vegetable transplanting operations.关键词
