Description

Technical Field

[0001] The invention relates to the technical field of cargo unloading devices in a ship's hold, in particular to a device for clearing residual dry bulk cargo in a ship's hold. Background Art

[0002] In the process of unloading bulk cargo at the port, the grab bucket, as the main unloading tool, can effectively grab the bulk cargo in the cabin one by one through its flexible movement up and down the hatch. However, as the unloading operation progresses, the bulk cargo at the bottom of the cabin gradually becomes difficult to grab directly, especially those scattered around the bottom of the cabin. They need to be concentrated in the middle of the cabin so that the grab bucket can operate more efficiently.

[0003] Under existing technical conditions, this link usually relies on the direct participation of the crew. The crew needs to go down to the cargo hold, and at the same time, the crane will lift heavy machinery such as forklifts into the cargo hold. In the narrow cargo hold environment where there may be safety hazards, the crew needs to operate these machines, such as driving a forklift, to collect and pile up the remaining bulk cargo. Although forklifts and other machines can pile up most of the materials with their powerful power, due to their operational limitations, a large amount of bulk cargo residue will still remain on the ground at the bottom of the cabin. These residues are often distributed in hard-to-reach corners or gaps, and the crew needs to manually collect and unload them.

[0004] This process not only greatly increases the labor intensity of the crew, exposing them to an environment that may pose safety hazards for a long time, but also makes the work efficiency extremely slow. Manual collection of bulk cargo residues is not only time-consuming and labor-intensive, but may also lead to uneven work quality, as human physical strength and attention are limited.
