The discharge pipes of the oil tank 19 and the oil pump 20 are connected to the swing mechanism 16 via the direction switching valve 21. Similarly, the oil pump 20 is connected to a hydraulic motor 23 via an electromagnetic valve 22, and the hydraulic motor 23 is a power source of the blower 9 for supplying compressed air to the nozzle 14. 24 shows an air pipe.

Next, the function and operation of this device will be described. Debris inside the hold, etc. can be removed by spraying compressed air while scraping off with the tip of the hydraulic shovel, and the operation of the hydraulic shovel and the swinging operation of the nozzle that sprays compressed air are all done by the operator from inside the cabin. The operating range of the hydraulic shovel can be changed vertically and horizontally. Also, the swing range of the nozzle can be arbitrarily changed according to the situation.

Moreover, the rocking speed of the nozzle and the setting of the compressed air pressure can be easily changed as required.

[Second Embodiment] FIGS. 5 to 8 show a second embodiment of the present invention.

The present embodiment is an example of a cleaning device for cargo handling onboard, which scrapes off powdery and granular solids adhering to the inner wall of a hold and the like, and then sprays and removes compressed air.

The hydraulic shovel 5 is mounted on the traveling device 7, which is grounded on the bottom 6 of the ship and can freely change the traveling direction, and on the upper part of the traveling device 7.
360 ° rotatable, swivel device 10 equipped with a cabin 8 for the operator, a blower 9 for supplying compressed air, and a swivel device 10
It consists of an approach mechanism 11 such as an articulated boom and arm mounted on the front part of the. A bucket 12 to which a chase 12a is fixed is connected to the arm 11a at the tip of the approach mechanism 11, and the arm 11a is connected to the tip of the boom 11b and the rear part of the boom 11b is connected to the turning device 10.
