The arrangement directions of the two third guide rollers 34 are respectively perpendicular to the arrangement directions of the two anti-loss plates 31. Guide rollers are provided on three sides of the two anti-loss plates 31, namely the first guide roller 32, the second guide roller 33 and the third guide roller 34, and the first guide roller 32, the second guide roller 33 and the third guide roller 34 are rotatably arranged. The extension of the movable boom assembly 1 drives the suction pipe 4 to extend. The extension of the suction pipe 4 will contact the rotatable first guide roller 32, second guide roller 33 and third guide roller 34, thereby preventing the suction pipe 4 from being worn during the extension of the movable boom assembly 1, avoiding or reducing the cracking or damage of the suction pipe 4, increasing the service life of the suction pipe 4, and avoiding affecting the emergency rescue efficiency due to the cracking or damage of the suction pipe 4. Specifically, in this embodiment, the shape of the third guide roller 34 is cylindrical, so as to avoid or reduce the wear on the suction pipe 4. It should be noted that the structure of the anti-loss mechanism 3 in this embodiment is not limited to this, and those skilled in the art can select other suitable anti-loss mechanisms 3 according to the teachings of this embodiment.

[0102] Specifically, in this embodiment, as Figures 1 to 6 shown, the suction pipe 4 passes through the two anti-loss plates 31 and adheres to the first movable arm 11, the second movable arm 12, the third movable arm 13, the fourth movable arm 14 and the fifth movable arm 15. The first movable arm 11, the second movable arm 12, the third movable arm 13, the fourth movable arm 14 and the fifth movable arm 15 are driven by the first driving oil cylinder 21, the second driving oil cylinder 22, the third driving oil cylinder 23 and the fourth driving oil cylinder 24 to extend, thereby driving the suction pipe 4 on the movable boom assembly 1 to extend, so as to expand the working range of the suction pipe 4. Since guide rollers are provided on three sides of the two anti-loss plates 31, namely the first guide roller 32, the second guide roller 33 and the third guide roller 34, and the first guide roller 32, the second guide roller 33 and the third guide roller 34 are rotatably arranged. The extension of the movable boom assembly 1 drives the suction pipe 4 to extend. The extension of the suction pipe 4 will contact the rotatable first guide roller 32, second guide roller 33 and third guide roller 34, thereby preventing the suction pipe 4 from being worn during the extension of the movable boom assembly 1, avoiding or reducing the cracking or damage of the suction pipe 4, increasing the service life of the suction pipe 4, and avoiding affecting the emergency rescue efficiency due to the cracking or damage of the suction pipe 4.

[0103] Please refer to Figures 1 to 6, this embodiment also relates to a suction excavation vehicle, which includes a frame assembly 100, an operation box 200, and the suction device 300 of the suction excavation vehicle in any of the above embodiments. The frame assembly 100 serves as the frame structure of the whole vehicle. It is the base of the whole vehicle, which plays a role in supporting and connecting each assembly of the whole vehicle, keeping each assembly in a relatively correct position, and bearing various loads inside and outside the vehicle. The operation box 200 is arranged on the frame assembly 100 and can be used to store materials. The suction device 300 is arranged on the frame assembly 100 and is used to extract materials into the operation box 200. Specifically, the materials in this embodiment are tiles, bricks, cement steel bars, soil, etc.

[0104] Specifically, in the suction excavation vehicle of this embodiment, as Figures 1 to 6 shown, during emergency rescue operations, the fan 400 in the suction excavation vehicle works, creating a negative pressure in the operation box 200. The suction head 5 sucks the materials through the suction nozzle 73 and into the operation box 200 through the suction pipe 4. When encountering hard or large soil, or densely piled stones and bricks, the driving component 71 drives the rotating component 72 to rotate. The rotating component 72 drives the suction nozzle 73 to rotate, causing the dispersing component on the suction nozzle 73 to rotate, so as to disperse and loosen the hard or large soil, or densely piled stones and bricks. The loosened soil is convenient to be extracted by the suction pipe 4. The operation is simple, time-saving and labor-saving, and the emergency rescue efficiency is improved.

[0105] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application, using the content recorded in the text and drawings of the specification of this application, and any technical solutions directly or indirectly implementing the above embodiments in other related technical fields are all included in the patent protection scope of this application.
