The electro-hydraulic servo synchronous lifting mechanism is mainly composed of an oil filter, an oil pump, a one-way throttle valve, a cartridge valve, an electro-hydraulic synchronous valve, a lifting oil cylinder, a stop valve, a pressure release valve and the like. The oil tank is connected with the oil filter, the oil filter is connected with the oil pump, the oil pump is respectively connected with the one-way throttle valve and the pressure release valve, the one-way throttle valve is respectively connected with the stop valve, the pressure gauge and the cartridge valve, the cartridge valve is respectively connected with the electro-hydraulic synchronous valve and the lifting oil cylinder, and the lifting oil cylinder is connected with the electro-hydraulic synchronous valve. The lifting hydraulic system of the product adopts an electro-hydraulic synchronous valve and has the functions of pilot control, load sensing, pressure compensation and the like, the output pressure and flow can not be influenced by load change, a lifting arm runs and lifts stably when the hydraulic system works, and the phenomena of up-down fluctuation and clamping stagnation cannot be generated when an agricultural implement is lifted; it is guaranteed that the lifting arm descends without buffering when bearing heavy loads, the sealing effect is good, performance is reliable, energy is saved, and the failure rate is greatly reduced.
