Abstract

The invention relates to a hinge type tool bit suitable for a push type pipe jacking machine and the push type pipe jacking machine. The hinge type tool bit comprises an outer side steel protection cylinder, a ground breaking device, blades, a connecting rod and a driving system. The ground breaking device is in a regular pyramid shape. Each edge of the regular pyramid at the bottom end of the ground breaking device is provided with a hinge device. One end of each hinge device is connected with the bottom end of the ground breaking device through a connecting piece, and the other end of each hinge device is connected with the corresponding blade through a connecting piece. Compared with the prior art, the regular pyramid-shaped ground breaking device is made of solid steel and provided with protruding thorns in the pushing direction, and the ground breaking function can be achieved in the pipe jacking process. At the bottom end of the ground breaking device, each edge of the regular pyramid is provided with the corresponding hinge device, and the hinge devices are fixedly connected with the bottom end of the ground breaking device through screws and can be detached and replaced. The other ends of the hinge devices are connected with the blade type blades with the protruding thorns, in other words, the blades are connected with the ground breaking device through hinges, the blades can be replaced at any time, the broken blade can be detached, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of underground non-excavation hole forming, in particular to a hinge-type cutter head suitable for a push-type pipe jacking machine and a push-type pipe jacking machine. Background technique [0002] At present, the traditional underground non-excavation hole-forming technologies mainly include shield machine hole-forming, pipe jacking machine hole-forming, and manual hole-digging technology. The machines used in the first two are mostly full-section circular flat cutter heads. A number of separate hobs, gear cutters, scrapers, and cutters are attached to the cutting cutterhead. The cutting cutterhead is connected to the power system through the main shaft. With the rotation of the cutterhead, the cutters chop the soil; the latter is purely manual. , balance the front soil pressure by reserving core soil. [0003] In the construction process of urban comprehensive pipe gallery and pipe curtain construction ...
