Abstract
The utility model discloses an electrical water valve control system for a self-propelled cotton picker, which comprises a control circuit, a hydraulic control valve feedback signal sampling circuit, a hydraulic control valve regulation reference signal sampling circuit and a display circuit. The hydraulic control valve feedback signal sampling circuit receives feedback signals about openness of a hydraulic control valve and transmits the signals to the control circuit. The hydraulic control valve regulation reference signal sampling circuit receives electrical signals from a regulation circuit and transmits the signals to the control circuit. The display circuit is electrically connected to the control circuit. The system is used for achieving accurate control of best water pressure value.
Description
Technical field
The utility model relates to the control system of cotton picker, particularly, relates to a kind of automatically controlled water valve control system that is used for self propelled cotton picker.
Background technique
There is large-area cotton planting in China, will use great amount of manpower to carry out the collection of cotton to the cotton collecting season, and cotton picker should be various technology limitation and is not widely used.The water valve control system of existing cotton picker mainly is the aperture through the step-wise adjustment water valve, thereby reaches the purpose of adjustment cotton picker hydraulic pressure.This control is open loop control, and the adjustment precision is difficult to control, the best hydraulic pressure value when being difficult to adjust to cotton picker work.
The model utility content
The purpose of the utility model is, to the problems referred to above, proposes a kind of automatically controlled water valve control system that is used for self propelled cotton picker, to realize the accurately best hydraulic pressure value advantage of control.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
A kind of automatically controlled water valve control system that is used for self propelled cotton picker; Comprise control circuit, hydraulic control valve feedback signal sample circuit, hydraulic control valve adjusting reference signal sample circuit and display circuit; Said hydraulic control valve feedback signal sample circuit is accepted the feedback signal of hydraulic control valve aperture; And this signal is transferred to control circuit; Said hydraulic control valve is regulated the reference signal sample circuit and is accepted the electrical signal of regulating circuit and this electrical signal is transferred to control circuit, and said display circuit is connected electrically on the control circuit.
