The dust suction structure 3 includes a dust suction device 31, and the dust suction device 31 drives the fan to rotate through a motor to generate negative pressure. The surrounding air and debris impurities are sucked into the dust collection device 31 together, the dust and debris impurities are separated by the filtering system, and then the clean air is discharged from the outside of the dust collection device 31. The left end of the dust collection device 31 is provided with a telescopic tube 32, which is a bellows and has telescopicity. The upper end of the telescopic tube 32 is provided with a dust suction port 33, and the rear end of the dust suction port 33 is provided with a connecting piece 34. The lower end of the connecting piece 34 is connected to a lifting cylinder 35.
