Description
Technical Field
[0001] The utility model belongs to the technical field of grab buckets, and particularly relates to a grab bucket for a ship unloader which is convenient for cleaning. Background Art
[0002] The grab mechanism is the core component of a ship unloader. It consists of two or more closable bucket-shaped jaw plates that form a material-containing space when combined. When loading, the jaw plates are closed in the material pile, and the material is grabbed into the material-containing space. When unloading, the jaw plates are opened in a suspended state on the material pile, and the material falls on the material pile. The material-grabbing equipment in the ship unloader mainly targets fragmented and granular materials, such as grain, coal, sediment, ore, etc.
[0003] After the existing grab bucket grabs sediment, some sediment will remain in the grab bucket. At this time, it is necessary for workers to manually clean it, which is cumbersome to operate and cannot achieve automatic and efficient scraping through structural improvement.

[0008] Further, a screw rod is threadedly connected in each through hole, and when the screw rod is tightened, the through hole is in a sealed state.
[0009] Further, the adjustment part of each screw rod is a hexagonal structure, and an adjustment groove is opened on the adjustment part of each screw rod. The adjustment groove is a hexagonal groove structure.
[0010] Further, a cleaning component is installed on each of the two inner connecting blocks. The cleaning component consists of a mounting arm, a spring rod, a cleaning block, a worm gear, a mounting block, a servo motor, and a worm. A mounting arm is rotated on each of the two inner connecting blocks, and the two mounting arms are both L-shaped rod structures.
[0011] Further, a spring rod is welded to the outer end of each of the mounting arms, and a cleaning block is fixed to the protruding end of each spring rod. The two cleaning blocks are respectively in contact with the inner walls of the two grab buckets.
[0012] Further, a worm gear is welded to each of the mounting arms, two mounting blocks are welded to each of the inner two connecting blocks, a worm is rotatably mounted on the front two mounting blocks, and a worm is also rotatably mounted on the rear two mounting blocks. The two worms are respectively engaged with the two worm gears.
[0013] Further, a servo motor is fixed to each of the front and rear mounting blocks. The output shafts of the two servo motors are respectively fixed to the two worms. The two servo motors are both electrically connected to an external control switch.
