Optimization and experiment of performance parameters for traction type square bundle harvester
摘要
Abstract
To address the challenges associated with straw collection,storage,and utilization,as well as the low operating efficiency and poor field adaptability of small-sized harvesting machinery in China,a traction-type square baler harvester integrating straw pickup,feeding,pre-compression,and baling operations was designed and developed.The kinetic characteristics of key components,including the pickup system and the feeding precompression mechanism,were analyzed to identify the main factors influencing machine performance and operational efficiency.A quadratic orthogonal rotational combination experiment based on RSM was conducted to optimize the operating parameters of the harvester.The machine forward speed,linear speed of spring rulers,linear speed of the rotor cutter,and speed of the feeding fork were selected as influencing factors.The missed pickup rate,conveying failure rate,and comprehensive performance score were used as performance evaluation indices.Experimental data were analyzed and optimized using Design—Expert software.The results showed that the optimal operating parameter combination consisted of a machine forward speed of 2.52 m/s,a pickup spring ruler linear speed of 3.68 m/s,a rotor cutter linear speed of 4.69 m/s,and a feeding fork speed of 190 r/min.Under these conditions,the comprehensive performance score reached its minimum value,indicating the best overall operating performance.Field validation tests further demonstrated that the missed pickup rate and conveying failure rate were reduced to 1.38%and 1.21%,respectively,while the comprehensive performance score was 1.32%.关键词
