Example Embodiment
[0025] The present invention will be further described below with reference to the drawings and embodiments.
[0026] Such as figure 1 , The value of the feeding amount is obtained by integrating the lower roll motor speed, the cutting motor speed, the coiling motor speed, the cutting circuit pressure, the conveying circuit pressure and the pressure of the traveling hydraulic system into the controller through comprehensive analysis in the control system. from. The rated feeding amount of this type of sugarcane harvester can be defined through specific test methods. The rated feeding amount is set when the controller is programmed. The remaining parameters are preset according to the rated feeding amount. When there is a difference between the parameter and the preset parameter, the controller will output the corresponding PWM signal for adjustment to bring it back to the preset parameter range. When the harvester is working normally, press the automatic harvesting control dial ...
