Problems solved by technology

When the yield of sugarcane is very low, in order to make the harvester reach the rated feeding amount, it is necessary to increase the driving speed to a large extent. Phenomena that meet the needs of normal operations
When the yield of sugarcane is very high, in order to prevent the harvester from being overloaded and causing blockage, the speed of the harvester should be reduced very low. At this time, the power of the engine cannot be fully utilized.
[0005] Due to the different sections in the sugarcane field, the density of the cane plants and the diameter of the rods are different, as well as the different degrees of lodging of the sugarcane, resulting in frequent changes in the load of the sugarcane harvester.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with drawings and embodiments.

[0026] Such as figure 1 , the value of the feeding amount is obtained by summarizing the lower roller motor speed, root cutting motor speed, coil motor speed, root cutting circuit pressure, conveying circuit pressure and walking hydraulic system pressure 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 the specific test method, and the rated feeding amount is set when the controller is programmed, and the rest of the parameters are preset according to the working conditions of the rated feeding amount, when each When there is a difference between the parameter and the preset parameter, the controller will output the corresponding PWM signal for adjustment, so that it returns to the preset parameter range. When the harvester is working normally, press the a...

Abstract

An electro-hydraulic control system for a sugarcane harvester. The highly reliable EPEC2023 controller and EPEC2025 display are selected. The walking system uses a hydraulic closed circuit composed of two proportional variable piston pumps and two double-displacement motors. Compared with the traditional sugarcane harvester, this type of harvester uses the controller to monitor the working status of the harvester in real time, deal with congestion in a timely manner, and increase the operating speed as much as possible without congestion, so that the harvester can run smoothly. homework; even if there is a jam, the jam phenomenon can be dealt with in a short time, greatly improving work efficiency.

Description

Technical field [0001] The invention relates to an electro-hydraulic control system of a sugarcane harvester, which is suitable for the mechanical field. Background technique [0002] The typical working conditions of the sugarcane harvester are mainly: transition working conditions, manual control working conditions, and automatic control working conditions. [0003] Analysis of transition working conditions: When transition is required, step on the foot switch and select the high-speed gear, then control the manual reversing valve to lift the crop divider and root cutter, and then control the driving joystick to make the vehicle walk. The devices are in a non-working state. Analysis of manual control working conditions: When the engine is started, step on the foot switch, press the function enable switch, and all actuators will start at the same time, and then use manual adjustment to adjust the crop divider and root cutter to the appropriate position, and then turn on W...
