Description

Technical Field

[0001] The utility model belongs to the technical field of ship grab buckets, in particular to an ore grab bucket for a ship unloader. Background Art

[0002] A marine grab is a heavy machine used for loading and unloading bulk materials on ships. Its main function is to grab and unload goods through the grabbing and releasing operation of the grab, thereby replacing manual labor and improving work efficiency and safety. In the prior art, the grab is connected to the mechanical arm of the crane through a hook. When the grab moves, it is easy to shake greatly, causing some ore to fall out of the grab. The amount of ore transported by the grab at a time is less than the capacity of the grab, which affects the handling efficiency of the grab. If a rigid connection is used between the grab and the mechanical arm, the above problems can be avoided. However, during the handling process, the impact caused by the collision when the grab contacts the ore pile is likely to damage the rigid connection position, which reduces the service life of the grab and also brings the safety risk of the grab falling off.
