Research On Adaptability Of Row Spacing Based On Corn Harvester With Finger Wheel

Our country has vast territory, due to topography,climate conditions such assoil conditions, temperature, humidity, rainfall, light and other differences, thebest suitable cropping patterns in different regions is different, resulting indifferences in corn planting spacing is large, restricted the development of cornharvest mechanization. Spacing adaptability has been one of the key factorsrestricting stage corn harvester regional operations, and also one of the mainconstraints to improve the yield of corn machine, therefore, no line-harvesttechnologies to improve corn harvest mechanization level to become the keytechnology. Based on the existing corn snapping device with finger wheel device,reference in practical harvesting process can not fully adapt to the various spacingrequirements, analyze the key components of the corn harvester, by theoreticalanalysis of the line does not meet the conditions to identify harvest technology,optimized for the device, and the analysis of the results in the prototype field trialsverified.According to the work process of corn harvester, to partition the work process,divided into crop divided area, lateral transport area, spiral feeding area,harvesting area, ear-rotor area, The fit parameters between the structuralparameters of each process and each component of the different parts, theoreticalanalysis, which can meet the requirements of the harvest. And the finger worksection in the process were defined, put forward in line with the requirements ofthe harvest with finger curve equation.In this paper, aim to solve the problem of spacing adaptability in cornharvester, theoretical analysis for the various components, and experimentalverification.
