This invention provides a shield machine cutterhead flushing device and a shield machine. The shield machine cutterhead flushing device includes a rotating shaft, a sleeve, and bearings. The rotating shaft is fixedly connected to the cutterhead, and the sleeve is fixedly connected to the shield body of the shield machine. The rotating shaft and the sleeve are connected by bearings. The rotating shaft includes multiple first flow channels extending axially. The rotating shaft also includes multiple first guide grooves, with the first end of each guide groove communicating with a first flow channel, and the second end of each guide groove extending to the outer wall of the rotating shaft. The first guide grooves corresponding to different first flow channels are positioned axially. The sleeve includes a second flow channel penetrating the sleeve. The second flow channel and the first guide grooves are positioned axially to connect the second flow channel and a portion of the multiple first flow channels during shaft rotation. This invention provides a shield machine cutterhead flushing device and a shield machine that can perform fluid flushing on multiple locations of the cutterhead, with strong flushing power and excellent effect.
