| description | The utility model relates to an electric proportional steering control device, which comprises a valve body, an oil inlet interface, a main oil return interface, a first steering interface, a second steering interface, a steering oil return interface, an electromagnetic directional valve, a main overflow valve and a proportional overflow valve, two execution oil ports of the electromagnetic reversing valve are correspondingly communicated with the first steering connector and the second steering connector, the main overflow valve is connected between the oil inlet connector and the main oil return connector, and the proportional overflow valve is connected between the steering oil return connector and the main oil return connector. The output pressure is controlled through the proportional valve, so that the turning radius of the harvester is controlled, and the control sensitivity is higher and more accurate.
