Parallel hybrid power combine harvester and control method

Abstract

According to the parallel type hybrid power combine harvester and the control method, an engine and a motor are coupled through a power coupling device, power obtained after coupling is input into a PTO and a power generator through a transfer case, and the parallel type hybrid power combine harvester is obtained by combining the structural characteristics and the working characteristics of the combine harvester. The threshing system with the largest power consumption and the walking system are directly driven by the PTO, and the header system, the cleaning system, the grass chopping system and other working systems with low power consumption and part of subcomponents of the working systems are all driven by independent motors. Mechanical decoupling among a plurality of working systems of the combine harvester is achieved through partial distributed electric driving, the problems that a transmission system of a traditional combine harvester is large in number of components, long in path and incapable of adjusting operation parameters in real time are solved, and the combined harvester has the advantages of being flexible in structural layout, high in energy utilization rate and the like; the application of the power battery and the motor can reduce the fuel consumption and carbon emission of the whole machine and improve the environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a parallel hybrid power combine harvester and a control method. Background technique [0002] At present, with the continuous improvement of the level of harvesting mechanization, the problems of massive energy consumption and environmental pollution have become increasingly prominent. The higher the requirements, the more urgent the demand for low-emission, low-pollution, low-noise green power agricultural machinery. Due to the diversification of crop varieties, as well as the differences in plant type, yield, grass-to-grain ratio, water content and other factors, the operating load of the combine harvester fluctuates greatly and the working conditions are complex and changeable. The traditional combine harvester uses a diesel engine + mechanical transmission to drive the chassis, header, threshing and cleaning and other components. The transmission s...

Problems solved by technology

[0003] Aiming at the above technical problems, the present invention provides a parallel hybrid power combine harvester and a control method, which solves the problems of traditional combine harvesters such as fuel consumption, large pollution, and serious loss of transmission power

The invention adopts the parallel hybrid power technology, so that the battery life and energy saving of the whole machine can be taken into account. At the same time, the invention combines part of the distributed electric drive to make the mechanical decoupling between multiple working systems of the combine harvester, which solves the problem of traditional combined harvesting. There are many components in the drive system of the machine, the path is long, and the operating parameters cannot be adjusted in real time. It has the advantages of flexible structural layout and high energy utilization rate.
