[0018] In this embodiment: the front end of the pipe body 1 is provided with a front docking component 2, and the rear end of the pipe body 1 is provided with a rear docking component 3. The pipe body 1 combines the front docking component 2 and the rear docking component 3 to form a conveying pipeline. The front docking component 2 cooperates with the rear docking component 3 on the adjacent pipe body 1 to perform the alignment and combination operation of adjacent conveying pipelines.

[0019] The front docking assembly 2 is composed of a first connecting disk 21, a second connecting disk 22 and a bottom plate 23. The second connecting disk 22 and the first connecting disk 21 are fixedly connected to the top of the bottom plate 23 one after the other. The first connecting disk 21 is fixedly connected to the front end of the pipe body 1, and the front docking assembly 2 is stably connected to the front end of the pipe body 1. The rear docking assembly 3 is composed of a fixing ring 31, a fixing block 32 and a combination screw 33. The fixing ring 31 is engaged with the corresponding first connecting disk 21 and the second connecting disk 22. There are two fixing blocks 32, and the two fixing blocks 32 are symmetrically slidably connected to the outer wall of the fixing ring 31. The fixing block 32 can move its position on the outer wall of the fixing ring 31 along the outer wall of the fixing ring 31, which is conducive to changing the position of the fixing block 32 on the outer wall of the fixing ring 31. The fixing block 32 is inserted with a combination screw 33 inside.
