Description

Technical Field

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

[0002] Ship unloader is a special machine that uses continuous conveying machinery to make a head that can lift bulk materials, or has the ability to take materials by itself, or is equipped with a taking and feeding device to continuously lift bulk materials out of the cabin, and then unload them to the arm or frame and transport them to the shore main conveying system. The grab of the ship unloader is the core device of the ship unloader, and the ship unloader generally uses a double-petal grab.

[0003] The utility model patent with patent application publication number CN 218371289 discloses a grab bucket for ship unloader with adjustable excavation resistance, comprising a rotating table, a mounting slot is provided inside the lower center of the top of the rotating table, a rotating motor is arranged inside the mounting slot, a motor shaft is arranged at the power output end of the rotating motor, a gripping mechanism is arranged on the top of the motor shaft, a hopper body is rotatably connected inside the left and right ends of the upper bottom of the rotating table, a protective cover is arranged on the outer surface of the hopper body, and adjustment buckles are arranged at the front and rear ends of the bottom of the protective cover. The grab bucket, through the setting of the gripping mechanism, can limit the opening and closing angle between the hopper bodies through the rotation of the lifting screw rod and the height of the lifting base block during the grabbing process, so as to avoid the opening and closing angle between the hopper bodies changing due to the pressure of the material after the bottom of the hopper body contacts the material, so as to avoid affecting the subsequent material grabbing work.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that when the device grabs and moves goods whose length exceeds the length of the grab bucket, there are only opening and closing plates on both sides of the grab bucket to squeeze the two ends of the goods for simple fixation, and the fixation of the two ends of the goods is not firm. Therefore, when the grab bucket tilts during the movement of the grab bucket, the goods are prone to slide out of the grab bucket from the side due to lack of fixation on the side, causing damage to the goods and danger to the people below. It lacks practicality, and therefore the ship unloader grab bucket cannot meet the needs of grabbing and moving longer goods.

[0005] Therefore, it is necessary to invent a ship unloader grab to solve the above problems. Utility Model Content
