Device for adjusting electro-hydraulic inclination angle of screen box of vibrating screen and method for using same

The invention relates to a device for adjusting an electro-hydraulic inclination angle of a screen box of a vibrating screen and a method for using the same, which belongs to a lifting technique of a drilling device for an oil field and overcomes the defects of other techniques. The device consists of an electric control system and a hydraulic system which are connected together, wherein a motor and an oil pump are connected in the electric control system, and the electric control system is connected with the motor through a cable and is provided with a control panel; an oil tank is connected with a hydraulic cylinder through a hydraulic pipeline in the hydraulic system; the electric control system is connected through the cable, the control panel controls the motor to rotate positively and negatively; and when the motor acts, the pump controls the connection and the disconnection of an oil way, hydraulic oil in the oil tank enters the hydraulic cylinder through the hydraulic pipeline so as to control the action of the hydraulic cylinder, and the hydraulic cylinder stretches to achieve the rising and the falling of the device so as to adjust the inclination angle. The device is not limited by a fixed position of the device, liberates manpower, and improves the working efficiency.
