Technical Field
[0001] The utility model belongs to the field of pipe jacking excavation devices, and specifically refers to an intelligent pipe jacking excavation robot. Background Technique
[0002] The pipe jacking technology is a non-excavation pipe laying construction technology used for municipal construction. Its advantages are that it has little or no impact on the surrounding environment, requires a small construction site, and produces little noise. Moreover, it can operate deep underground, which is an incomparable advantage of open-cut pipe laying. However, the pipe jacking technology also has disadvantages, such as a long construction time and high project cost. And during the process of laying pipes underground, a hydraulic machine is needed to push the pipe into the soil. During the pipe jacking process, manual excavation is carried out, and pipe jacking is carried out while excavating, so as to complete the pipe jacking operation. Manual pipe jacking requires excavation and transportation of soil, which is extremely troublesome, so the labor cost is relatively high.
[0003] In recent years, although some intelligent pipe jacking equipment has emerged, although it can mechanically extract and discharge crushed soil, the viscosity of the crushed mud is relatively high, and it is relatively inconvenient to extract, which to a certain extent affects the pipe jacking efficiency.

[0006] Furthermore, the pipe jacking main body further includes a connecting pipe jacking and a jacking iron. The connecting pipe jacking is movably connected to the jacking head. The connecting pipe jacking is slidably connected to the limit guide rail. A clamping groove is opened on the rear side of the jacking head. A clamping block is fixedly arranged on the front side of the connecting pipe jacking. The clamping block is slidably and fittingly connected to the clamping groove.
[0007] Furthermore, the jacking iron is slidably connected to the limit guide rail. A blocking block is fixedly arranged on the rear side of the connecting pipe jacking. The jacking iron is abutted and connected to the blocking block.
[0008] Further, the soil crushing mechanism includes a first motor and a crushing cutter head. The crushing cutter head is rotatably connected to the front side of the top head and penetrates through the top head.

[0011] Further, hoses are externally connected to the rear sides of both the external connecting pipe and the water supply pipe.
[0012] The beneficial effects achieved by the present utility model with the above structure are as follows:
[0013] For the intelligent pipe jacking excavation robot proposed in this solution, by arranging a mud discharging mechanism at the lower inner side of the top head, injecting water into the mud discharging groove, and being able to quickly reduce the viscosity of the soil crushing mud under the stirring and mixing of the stirring roller, it is convenient for the mud suction pump to discharge the mud, increasing the advancing speed of the pipe jacking.

[0022] As Figures 2-3 shown, the pipe jacking main body 2 further includes a connecting pipe jack 202 and a jacking iron 203. The connecting pipe jack 202 is movably connected to the pipe head 201. The connecting pipe jack 202 is slidably connected to the limit guide rail 101. A clamping groove 206 is opened on the rear side of the pipe head 201.
