Abstract

The invention discloses a jacking machine cutterhead. The jacking machine cutterhead comprises a jacking plate and a central controller; the jacking plate is circular; a drilling tool is arranged on the front end face of the jacking plate in the jacking direction; a first motor is fixed to the rear end face of the jacking plate; the drilling tool is connected with a power output shaft of the first motor; the first motor is connected with the central controller through electric signals; the drilling tool comprises a central drilling tool body and edge drilling tool bodies; a center shaft of the central drilling tool body corresponds to the circle center position of the jacking plate; the edge drilling tool bodies are evenly distributed with the circle center of the jacking plate as the center; a central shaft of the central drilling tool body is horizontally arranged; and central shafts of the edge drilling tool bodies are arranged in a radial shape with the circle center of the jacking plate as the center. The jacking machine cutterhead has the beneficial effects that the rock breaking capacity is high, jacking of the drilling tool is rapid, and the problem that an existing jacking machine cutterhead gets stuck easily is solved.

Description

technical field [0001] The invention belongs to the technical field of underground pipe jacking engineering equipment, and in particular relates to a jacking machine cutter head. Background technique [0002] Pipe jacking technology is a commonly used trenchless technology, which can safely cross roads, railways, rivers, and even pass under buildings, effectively protecting the environment. The construction of pipe jacking technology does not require partition construction, avoiding the impact of excavation on traffic, damage to road surface, damage to surface vegetation, normal activities and daily life of residents, and a large number of earthworks, which greatly shortens the construction period. However, the existing pipe jacking machines have poor rock-breaking ability, slow jacking, and even the situation that the cutter head is jammed and cannot continue jacking. Contents of the invention [0003] In order to solve the problems of poor rock-breaking ability, slow ja...
