In one embodiment, the suction cup 41 is an elongated suction cup 41 and the length direction thereof is parallel to the Y direction, so as to be better suitable for bulk material cleaning in the gondola 8; the length of the suction cup 41 may be slightly less than the width of the area to be cleaned (e.g. the width of the truck 8) to ensure cleaning effectiveness and efficiency. Further, the area of a suction opening of the suction cup 41 can be adjusted to meet the working requirements of areas to be cleaned with different widths, and the adjustment mode can be realized by respectively arranging movable baffles at two ends of the suction cup 41 (the movable baffles can be chain plates and are arranged inside the suction cup 41 in a drag chain mode).

It is understood that the material receiving side of the suction cup 41 is the side of the suction cup 41 close to the space outside the crane 3. The dividing plate 44 is used for cutting the bulk material/bulk material with high water content, and preventing the mud-shaped bulk material from being bonded into a large material which cannot be sucked, so that the bulk material cleaning effect can be correspondingly improved. As required, a plurality of partition plates 44 may be provided on each suction cup 41, and the partition plates 44 are sequentially arranged at intervals in the Y direction.

In an alternative embodiment, as shown in fig. 3 and 4, the tray frame of the suction cup 41 is provided with a nozzle 45, and the nozzle 45 is a dual-medium nozzle.

In the structure, the conveying pipe 6 is lifted along with the lifting frame 3, and the outlet end 63 of the conveying pipe 6 is lifted along with the lifting frame, so that the conveying pipe is inserted into or separated from the socket 72; specifically, the method comprises the following steps: when the lifting frame 3 descends, the conveying pipe 6 descends, and after the outlet end 63 of the conveying pipe 6 descends to contact the sealing ring 722, the sealing ring 722 is gradually compressed to realize the sealing between the conveying pipe 6 and the socket 72; when the lifting frame 3 is lifted, the conveying pipe 6 is lifted along with the lifting frame, the outlet end 63 of the conveying pipe is separated from the socket 72, and the pneumatic suction and pickup mechanism is in a non-working state, so that the separation of the conveying pipe 6 from the suction unit 7 cannot be influenced negatively.
