The electromagnetic three-way pump 9 is arranged between the oil delivery pipe 7, the connecting pipe 8 and the oil return pipe 10. The transfer box 11 is installed on the top of the oil tank 2. The end of the oil return pipe 10 away from the electromagnetic three-way pump 9 is fixedly connected to the transfer box 11. The second filter 13 is installed inside the transfer box 11. The transfer box 11 is connected to the oil tank 2 through the second filter 13; the mounting shell 3 is installed on the side of the oil tank 2 away from the oil delivery pipe 7. The pipe 8 is connected to the equipment, and by operating the regulating switch 15, the controller 14 receives the information of the regulating switch 15, and then controls the electromagnetic three-way pump 9 to change the oil delivery direction, and transports the hydraulic oil to the inside of the transfer box 11 through the return oil pipe 10. The hydraulic oil in the transfer box 11 is then returned to the inside of the oil tank 2 through the second filter 13, so as to achieve the effect of emergency oil return. The controller 14, the regulating switch 15 and the alarm 16 are installed on the top of the front end of the oil tank 2. The alarm 16 is arranged on the rear side of the regulating switch 15, and the controller 14 is arranged on one side of the regulating switch 15. Through the setting of the regulating switch 15 and the controller 14, it is convenient for the staff to operate and control the oil return component.

[0026] In order to improve the anti-blocking performance, an anti-blocking component for preventing blockage is provided outside the oil return component;

[0027] like Figure 1-5 As shown, the anti-blocking component includes a mounting shell 3, an electric heating plate 4 is installed inside the mounting shell 3, a heat conducting plate 5 is installed on the side of the electric heating plate 4 close to the mounting shell 3, the end of the heat conducting plate 5 away from the electric heating plate 4 passes through the mounting shell 3 and extends to the outside of the mounting shell 3, a sealing plate 6 is provided on the side of the electric heating plate 4 away from the heat conducting plate 5, a liquid level sensor 17 is installed on the top of the transfer box 11, and the bottom end of the liquid level sensor 17 extends to the inside of the transfer box 11.
