Description

Leak-proof closing mechanism of ship unloader grab bucket Technical Field The utility model relates to the technical field of ship unloader grab buckets, in particular to an anti-scattering and anti-leakage closing mechanism of a ship unloader grab bucket. Background The ship unloader is a special machine which is made of continuous conveying machinery, can lift the bulk materials, has self-taking capability or is matched with a material taking and feeding device, continuously lifts the bulk materials into a cabin, and then is unloaded to an arm support or a frame and can be conveyed to a local conveyor system of a shore main conveying. The grab bucket is a core device of the ship unloader, and the ship unloader generally uses a double-petal grab bucket. The existing grab bucket is worn and closed seriously after grabbing materials for a long time, so that the possibility of leakage is easy to happen when grabbing materials such as fine coal and fine sand, and the whole grab bucket needs to be replaced at the moment, so that the cost is increased. According to the grab bucket device of the ship unloader disclosed by the Chinese patent with the publication number of CN217650733U, through installing the first insert on the left grab bucket and installing the second insert on the right grab bucket, the first insert and the second insert are respectively connected with the left grab bucket and the right grab bucket through a plurality of fixing bolts, gaps appear when the first insert and the second insert are worn and closed in the process of grabbing materials for a long time, and at the moment, the first insert or the second insert can be detached through disassembling the fixing bolts, so that the first insert or the second insert can be replaced, the whole left grab bucket and the right grab bucket are not required to be replaced, and the cost is saved. However, when the grab bucket device is in actual use, the edges of the grab bucket are mutually staggered to generate larger pressure, so that the first insert and the second insert can be replaced more frequently, and the ship unloader is required to stop the grab bucket in the process, so that unloading efficiency is affected.
