Embodiment 1
[0034] Embodiment 1, a kind of anti-clogging cutter head spout, such as figure 1 As shown, it includes a cylinder communicated with the injection port on the front panel 4-1 of the cutterhead, and the cylinder is communicated with the liquid supply pipe 3, and the liquid supply pipe 3 sprays foam agent to the front of the front panel 4-1 of the cutterhead through the cylinder or bentonite. A rotating shaft 2-1 with blades 2-2 is arranged in the inner cavity of the cylinder, and a weight 5 is arranged at the rear end of the shaft 2-1, and the shaft 2-1 is connected to the non-rotary part of the weight 5 At the position of the center of gravity, a sealing structure is provided between the weight 5 and the inner cavity of the barrel, and the weight 5 is covered with a protective housing 8 whose inner cavity is larger than the rotation space of the weight.
[0035] like Figure 4 and Figure 5 As shown, the cutter head rotates clockwise, and the weight 5 always points verticall...
Embodiment 2
[0042] Embodiment 2, an anti-clogging cutter head nozzle, the blade 2-2 is a helical blade, and when the weight 5 drives the shaft 2-1 to rotate, the slag discharge direction of the helical blade is the same as the liquid outlet direction of the inner cylinder 2 . When the blades 2-2 rotate, they can both effectively stir and discharge the slag in the inner tube 2 to the outside.
[0043] Other structures of this embodiment are the same as those of Embodiment 1.
