[0046] As shown, Figure 3 The main water pipe 7 is vertically connected to the water pump in the middle of the ditching machine body 1, and the first water outlet pipe 8 is connected to the bottom of the main water pipe 7 and arranged horizontally. The second water outlet pipe 9 is connected to the both ends of the first water outlet pipe 8 and arranged downward outside the both sides of the middle installation frame 202. The lateral water pipe 10 is arranged outside the platform support frame on both sides of the ditching machine body 1.

[0049] In the specific use process:

[0050] Pipe-laying followed by trenching mode: The trenching machine body 1 is mounted on the mobile work platform 2. After the bottom of the trenching machine body 1 is installed in the installation groove of the middle installation frame 202, the trenching machine is equipped with a special water pipe and works in conjunction with the mobile work platform 2 to perform trenching operations on the already laid pipes 4.

[0051] The specific adjustment process is as follows:

[0052] The hydraulic telescopic rod 301 drives the movable support 304 of the folding bracket to rotate along the transverse support 303, thereby causing the driving wheel on the second fixed plate 305 at its end to change its walking angle position, adjusting the distance between each set of relatively set tires 302 and the tilt angle of each set of tires 302, so as to match it with the actual cable laying pipeline size, significantly improving the efficiency of underwater cable laying work.

[0053] Meanwhile, the lateral telescopic frame above the walking tire mechanism 3 can be further adjusted. By controlling the expansion and contraction of the lateral telescopic frame, the distance between the two sets of walking tire mechanisms 3 can be adjusted to expand or shrink. At the same time, the width of the inner front and rear telescopic frames and the first water outlet pipe 8 can be adjusted, thereby further adjusting the matching pipe size adjustment requirements between the two sets of walking tire mechanisms 3. The width position of the matching water outlet pipe is also adjusted simultaneously, which enhances the synergistic effect and significantly improves the dredging operation efficiency of the dredging machine body 1. It is easy to adjust, meets the actual use requirements, and has a wide range of applications.

[0054] The tires 302 of the drive wheel of the bottom walking tire mechanism 3 of the mobile work platform 2 rest on the cable laying pipeline, and the drive wheel is driven to rotate by the walking motor 306.

[0055] The water pump drives a high-pressure water flow downward from the main water pipe 7, and then sprays it vertically downward from the first outlet pipe 8 at the bottom and the second outlet pipes 9 extending downward from both sides of the middle mounting frame 202. At the same time, the lateral thrusters 11 on the trenching machine body 1 spray a large flow of low-pressure water downward; the lateral water pipes 10 on both sides of the trenching machine body 1 also discharge lateral water flows to the bottom of both sides of the extended platform support frame. The combined action of these water flows completes the trenching operation after pipe laying.

[0056] like Figures 4-5 As shown, when adjusting the trenching-then-pipe-laying mode: the hydraulic telescopic rod 301 drives the moving bracket 304 of the folding bracket to rotate along the transverse bracket 303, thereby driving the driving wheel on the second fixed plate 305 at its end to change the walking angle position, adjusting the distance between each set of relatively set tires 302 to open, so that the tires 302 are in the road walking state, and the trenching-then-pipe-laying work can be carried out directly. The two modes can be adjusted at any time, which significantly improves the efficiency of underwater cable laying.

[0057] In summary, the walking blow ditch machine has the advantages of ingenious device structure, the special water pipe pipeline and the operation platform cooperatively installed on the blow ditch machine, two working modes of a blow ditch first and pipe laying second mode and a pipe laying first and blow ditch second mode can be realized, the blow ditch first and pipe laying second mode in the prior art can be met, the blow ditch operation on the pipe 4 which has been laid can be met, the underwater cable laying work efficiency is remarkably improved, and the actual use requirements are met.

[0058] The above is only a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all should be covered in the protection scope of the utility model.
