Document Type and Number:
WIPO Patent Application WO/2023/125651
Kind Code:
A1
Abstract:
Disclosed is a cutter device. The cutter device comprises a sleeve (2), a rotating sleeve (3), and a cutter assembly (1); the sleeve is provided with an inner cavity; the rotating sleeve is disposed in the inner cavity of the sleeve and is rotatably disposed relative to the sleeve around a first rotating shaft extending in a first direction (Z), and the rotating sleeve comprises a channel passing through in a second direction (X); the cutter assembly comprises a cutter holder (11) and a cutter (12) disposed in the cutter holder; the cutter is rotatably disposed relative to the cutter holder around a second rotating shaft extending in a third direction (Y); the first direction, the second direction, and the third direction are perpendicular to one another; and the outer wall of the cutter holder is in sealing fit with the inner wall of the channel, and the cutter holder is movably disposed in the channel in the second direction. According to the cutter device, the sealing performance is guaranteed by means of the sealing fit of the outer wall of the cutter holder and the inner wall of the channel, and compared with gate sealing in the prior art, the sealing saves gate space, thus the arrangement of a smaller cutter distance can be achieved, and the space of a cutterhead is fully utilized. Further disclosed are a tunneling machine and a cutter changing method.
