Ｏ用コネクタ構造。 The hydraulic pump 9 and the control valve 16 for PTO work equipment are connected, and two oil passages, a hydraulic oil passage A39 and a hydraulic oil passage B40, are connected to the control valve 16 for the PTO working machine so that they can be switched freely. The first PTO working machine 17-1 is connected to the tip of the hydraulic oil passage A39, and the other hydraulic oil passage B4 is connected to the first PTO working machine 17-1.
0, a connector body 42 to which the second PTO working machine 17-2 can be connected and a three-way valve body 43 having a three-way switching valve 50 are integrally connected and positioned. A return pipe 44 connected to the oil tank 10 is provided, and the first PTO working machine 17-1 is connected to the tip of the three-way valve body 43 via a hydraulic oil path C51, and a three-way switching valve 50 is provided. By switching, the hydraulic oil passage C51 and the return pipe 44 can communicate with each other, or
PT in a power excavator, characterized in that the hydraulic oil passage C51 and the hydraulic oil passage B40 can communicate with each other.
O connector structure.
