A kind of external cutter disc mud cake flushing device

Abstract

The utility model discloses an external formula cutter head mud cake flushing device belongs to shield machine technical field. A kind of external formula cutter head mud cake flushing device, including shield machine cutter head, the periphery of the surface of shield machine cutter head is respectively provided with five one-way cleaning components, and the center of the surface of shield machine cutter head is provided with four bidirectional cleaning components, the one-way cleaning component and bidirectional cleaning component are all by through pipe and flush pipe fitting composition, wherein, the inside of bidirectional cleaning component is provided with two flush pipe fittings. To solve the problem that the surface of cutter head of existing shield machine will accumulate a large amount of mud cake in the process of advancing, prone to cause the deviation of shield machine and overload, adopt the layout strategy of center and periphery, five one-way cleaning components cover cutter head periphery high flow rate area, four bidirectional cleaning components focus on the care center low flow rate easy mud cake area, this partition targeted design ensures the all-round coverage of cutter head panel, mud cleaning has no dead angle.
