The invention discloses a
machine head suitable for updating a
reinforced concrete pipeline through a fragmentation method, and belongs to the technical field of pipeline updating devices. The machinehead comprises a shell body, wherein a plurality of wind picks are uniformly arranged at the front end of the shell body, and a
drill bit is fixed to the front end of each air pick; a pulling head isarranged in the middle of one end, where the air picks are arranged, of the shell body; a storage chamber is arranged inside the shell body, wherein a hopper is arranged at the front end of the storage chamber; the rear end of the storage chamber is provided with a
cutting chamber, wherein the storage chamber is connected with the
cutting chamber through a transition section, and the transition section is a conical structure with a large opening and close to the storage chamber end; a
cutting machine for cutting steel bars is arranged at the front end of the inner part of the cutting chamber;and the bottom of the storage chamber is provided with a discharging port I, the bottom of the cutting chamber is provided with a discharging port II, and the discharging port II is located behind the cutting
machine. According to the machine head suitable for updating the
reinforced concrete pipeline through the fragmentation method, by adopting the above structure, the problem that soil aroundthe
reinforced concrete pipeline is prone to disturbance due to the fact that the reinforced concrete pipeline is not easy to update can be solved, and the advantages of simple structure and high working efficiency are achieved.
