Structural design and experiment of picking and baling machine for wasted straw in field
A self-propelled straw picking and baling device has been designed to address the issues of low mechaniza-tion and high manual labor intensity in the harvesting of wasted straw in the fields of southern regions.It can com-plete integrated operation processes such as straw picking,feeding,conveying,and compression into bales,which can effectively promote the comprehensive use of straw resources.In this paper,the structural parameters of the key moving parts of the whole machine were calculated and designed,and the motion laws of different unit points of the compression device were obtained through simulation.Then the constrained mode simulation of the main frame was completed in ANSYS,and the relationship between natural frequency and multi-source excitation of the body was ob-tained.Finally,field harvesting experiments were conducted on the entire machine to comprehensively evaluate its operational performance.The results showed that the baling rate and regular baling rate were 98.94％ and 97.47％,respectively.The average size of formed straw bales was 65 cm × 50 cm × 36 cm,with an average mass of 16.02 kg,the density of 137.42 kg·m-3,the resistance rate of 96.25％,the total loss rate of 2.95％,and the pure working hour productivity of 0.8325 t·h-1 .This study can provide reference for the development and subsequent optimiza-tion of the integrated machine for picking,transporting,and baling wasted straw in field.
