Walking cruising proportion control device and excavator

The invention discloses a walking cruising proportion control device and an excavator, and belongs to the field of mechanical control. The walking cruising proportion control device comprises a first walking control valve 3 which is connected with a main pump 2 through a first pilot valve 1, a controller 4 used for controlling opening and closing of pilot valves, a first pressure sensor D1 used for sensing pressure, and a third pilot valve 5. The first pressure sensor D1 is arranged in a pilot oil way of the first pilot valve 1 and is connected with the controller 4, the controller 4 is connected with the third pilot valve 5, the main pump 2 is connected with the third pilot valve 5, and the third pilot valve 5 is connected with the first walking control valve 3. According to the technical scheme, the pressure sensor senses the pressure of the oil way during walking, the controller controls the pressure in a cruising loop to be equal to that during walking, and therefore the aims of vehicle speed cruising and
