Abstract


The Chinese rapeseed planting area of ??more than 1.1 million hectares, accounting for about 1/3 of the world's rapeseed acreage, the highest in the world. Chinese rapeseed mechanized harvest level is less than 10%, which restricts the rapeseed industry development. Develop a sub-windrower to solve Rape branching maturity inconsistent actual production stage of research to solve the problem of rape mechanized harvesting one of the priorities. The theoretical analysis and computer simulation of rapeseed mechanization segments harvest developed a rapeseed swather, to carry out its overall design and its key components, mainly to carry out the following work: (1) in the comparative analysis of domestic and international rapeseed based on harvest Research carried out an implementation of the overall design of the rapeseed segments harvested rape swather analysis to determine the machine works, the work process and its basic structure, the overall performance of the aircraft, and analysis of calculated parameters and performance parameters of the basic structure of the machine. (2) than the system designed to adapt segmented harvest cutting systems, on the application of kinetic and kinematic analysis and computer simulation cutting characteristics to meet the cutting rapeseed stalk requirements, and rapeseed cutting area of ??mathematical calculation model and cutting the regional rapeseed stalk stubble height model, using MATLAB software by M files convenient prepared to come to the cutting diagram and three-dimensional graphics cutting height, and on this basis to establish the cutting area than the cutting height difference model, by solving model to optimize the combination of parameters derived from the re-cut area and leakage cut area and overall a 6.47% reduction in the ratio of the cutting area, cutting height neat significantly improved. (3) carried out by the vertical roller assembly, the telescopic the finger roller assembly and conveyor assembly composed conveyor systems integration design, to change a single vertical or horizontal transport model, combined with of rapeseed stalk materials and planting characteristics delivery system developed structure and operating parameters field trials proved rapeseed stalk smooth transport. (4) Based on Pro / E completed Rape swather machine 3D modeling and simulation analysis of interference checking, to achieve the correction of the initial design parameters; simultaneously by the finite element model of the Rape swather rack-state analysis, the resulting rack sixth-order natural frequency values ??and different form of modal performance indicate that the design of the rack without resonance excitation phenomena, can guarantee the smooth working of the rapeseed cut drying machine. (5) the 4SY-1.8 napus swather test developed, the aircraft satisfy to the rape stalk effective cutting transportation unobstructed placement uniform requirements.
