Design and Testing of Tea Garden Crawler Plowing Machine
摘要
Abstract
In response to the problems of inadequate agricultural equipment and poor slope performance in tea gardens of hilly areas,a tracked ploughing machine suitable for hilly tea plantations was designed and developed,with a focus on slope performance.The main structural parameters of the chassis were designed,and the dynamic simulation was used to analyze the machine's ability to traverse across and along slopes.The simulation results show that the maximum slope for the machine to traverse across was 22°,and the maximum slope for the machine to traverse along was 31°.To explore the quality of excavator tillage,based on the theoretical analysis of the tillage movement trajectory,the tillage advance speed was optimized by dynamics,and the optimal tillage advance speed of 400-450 mm·s-1 was obtained for excavators.To further verify the rationality of the parameters and the reliability of the simulation results,field tests were conducted on uphill slopes.The results show that the maximum climbing ability of the machine on uphill slopes was 32°,with an error of 3.22％compared to the theoretical climbing angle.The results validate the accuracy and reliability of the theoretical calculations and simulations,demonstrating that the designed ploughing machine has good maneuverability and can fully meet the uphill climbing needs of hilly areas,providing an effective solution to the problem of tea plantation cultivation.关键词
