in the pure electric mode, the control system 20 controls the engine 30 to stop, all working parts of the combine harvester stop, and the driving system 50 is driven to work only by the power battery 36;
in the hybrid power mode, the control system 20 controls the engine 30 to work and drives the generator 35 to generate power, a part of the electric quantity generated by the generator 35 is directly used for consumption of working parts, and a part of the electric quantity is stored in the power battery 36;
in the PTO mode, the control system 20 controls the engine 30 to work and cuts off the power for driving the generator 35 through the clutch 34, all the power of the engine 30 is transmitted into a power output shaft PTO33 for driving the roller 41 of the threshing system 40 and the fan 61 of the cleaning system 60 to work, and the header system 10, the cleaning system 60 and the running system 50 are powered by the power battery 36;
in the driving charging mode, the control system 20 controls the engine 30 to work and drives the generator 35 to generate power, the power generated by the generator 35 is only used for driving the driving system 50 and charging the power battery 36, and the rest of the working components are stopped.
In the parking charging mode, the control system 20 controls all the working components to stop, and charges the power battery 36 by an external power source, or charges the power battery 36 by driving the generator 35 through the engine 30.
The engine 30 and the battery 36 of the invention are the energy sources of the whole machine, and combine with the reducer 31, the transfer case 32, the generator 35 and other parts to form the power system of the whole machine. When the work load of the combine harvester exceeds a preset value, the clutch 34 cuts off the power to the generator 35, so that the most power of the engine 30 is used for driving the threshing system 40 to ensure the work quality. In addition, the power output shaft PTO33 drives the threshing system 40 to work through a transmission device, in order to ensure that the threshing cylinder 41 can keep the relative constant of the rotating speed under the condition of large load fluctuation in the working process, the rotating speed of the power output shaft PTO33 is monitored in real time through the sensor 23, and the engine 30 is adjusted in real time to achieve the purpose of power compensation, so that the rotating speed of the threshing cylinder 41 is stabilized. The electric power generated by the generator 35 is used to drive each motor and charge the power battery 36. Because the present invention employs a distributed electric drive technique to achieve mechanical decoupling between the various working components as much as possible, the engine 30 does not have to be operated at maximum horsepower at all times compared to conventional combine harvesters. In the invention, based on the MAP of the engine 30, the ideal working curve of the engine 30 is calibrated, and the whole vehicle controller 21 controls the rotating speed of the engine 30, so that the engine 30 always works in an ideal interval, and the power battery 36 can be charged by an external power supply or a generator 35.
In the invention, each motor is a motor which works independently and is powered and driven by the power battery 36 and the generator 35, and a driver can adjust the motor rotating speed of each working part according to different attributes of crops so as to better adapt to the requirements of different working conditions. In addition, in order to ensure the stability of the working performance of the combine harvester, when a driver selects the required motor rotating speed, the constant rotating speed control is carried out on each motor, the rotating speed of each motor is monitored through the rotating speed sensor 23, the rotating speed state is transmitted to the vehicle control unit 21 in real time, and when the working load of the motor changes, the load voltage of the motor is adjusted through the motor controller 22 so as to stabilize the rotating speed of the motor, so that the stable working of the combine harvester is ensured.

During operation, the stalk and stem of the crop are pushed in by the reel 11 and cut by the cutter 12, and the harvested crop is gathered by the header auger 13 and conveyed to the threshing system 40 via the conveyor belt 14.
The threshing cylinder 41 of the threshing system 40 is a system with the largest power consumption of the whole machine, and is driven to operate by a power output shaft PTO35, and the power on the power output shaft PTO35 drives the threshing cylinder 41 to rotate through a belt transmission wheel 35b, a belt transmission wheel 43 and a power transmission device 42. The crop threshed by the threshing system 40 will be further processed by a cleaning system 60.
The running system 50 is provided with two independent left wheel side motors 51a and right wheel side motors 52a which respectively drive the left driving wheel 51 and the right driving wheel 52, so as to drive the whole machine to advance and turn.

Crop grains, stems, chaffs and other impurities subjected to threshing by the threshing system 40 fall into the cleaning system 60 under the action of gravity, the grains and the impurities falling on the head are separated from each other due to different specific gravities under the shaking and throwing action of the shaking plate, the grains are further screened out by the fish scale screen 62e and the weaving screen 62g, in the process, the air flow blowing action of the fan 61 is received, the light chaffs and broken drafts are blown out of the machine, clean grains fall into the bottom plate 63 and slide to the grain auger 65a, the grains are further conveyed to the grain tank 71 through the grain conveying cylinder 72 of the grain storage system 70, the impurities and broken ears which are not removed completely fall into the bottom plate 63 through the sieve pores of the tail screen 62f and slide to the impurity auger 64b, are sent back to the threshing system 40, and are threshed again and cleaned in the cleaning device 60.
