Agricultural machinery hydraulic system


Agricultural machinery hydraulic system uses the flow of liquid and the force of pressure transfer to achieve energy transfer. Its main components include hydraulic pumps, hydraulic valves, and hydraulic actuators. As a power source, the hydraulic pump converts mechanical energy into hydraulic energy through rotary movement, and then through the control of the hydraulic valve, the hydraulic oil flows according to the predetermined path, and the pressure generated when the hydraulic oil flows is used to drive the hydraulic actuators, such as hydraulic cylinders and hydraulic motors, which can move in a straight line or rotation, so as to realize the control of the agricultural machinery and the adjustment of the working position.


1. Traditional rear suspension hydraulic system

The traditional rear suspension system is mainly composed of three major parts of suspension hydraulic system, suspension mechanism and agricultural machinery, in order to realize the operation of tractor control agricultural machinery, agricultural machinery needs to be fixedly connected with the tractor through the suspension mechanism, and the driver realizes the adjustment of the position and attitude of the agricultural machinery by controlling the hydraulic handle on the tractor, so as to complete the farmland operation with different requirements. The hydraulic system mainly includes oil pump, distributor, hydraulic cylinder and other auxiliary components, the principle is that when the oil pump provides hydraulic pressure for the hydraulic system, the driver operates the hydraulic handle, and the distributor adjusts the flow and direction of the hydraulic oil according to the position of the handle, so as to realize the extension and contraction of the hydraulic cylinder, so as to ensure that the agricultural machinery reaches the required working position. In the traditional rear suspension hydraulic control system, the position adjustment for agricultural machinery is completed by mechanical control, because the control of mechanical mode needs to be realized by pull rod and elastic element, the structure is relatively complex, and long-term use may make parts deform and produce the hysteresis of hydraulic reaction, affect the actual working effect.


2. the new rear suspension hydraulic system

Since the mechatronic and hydraulic integration technology has been widely used in agricultural machinery, the electronic control system of the tractor has achieved effective integrated control of the tractor's power shift, instrument and differential unit control and battery management, and the new rear suspension system mainly includes a three-point suspension mechanism, a hydraulic pump, a depth control valve, an oil cylinder, an electronic control element and a sensing monitoring device. Taking tillage as an example, due to the large number of applications of sensing and detection technology, the detection parameters of the sensor can be transmitted to the processor for analysis, and through the comparison of traction force and tillage depth parameters, the drive valve can be scientifically controlled to realize the lifting or lowering of agricultural machinery and tools, so as to ensure the scientificity of ploughing operations. Compared with the traditional mechanical control structure, the new rear suspension system uses electronic control instead of mechanical structure, which effectively reduces the probability of mechanical failure, and at the same time accelerates the response speed and makes the control more flexible.


Agricultural machinery hydraulic systems play a vital role in agricultural machinery, and proper use and timely maintenance can help improve the efficiency and life of agricultural machinery.
