[0002] A grab bucket is a special tool for a crane to grab dry bulk goods. It consists of two or more openable and 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 opening and closing of the jaw plates are generally controlled by the steel wire rope of the crane's hoisting mechanism. Grab bucket operation involves no heavy physical labor, can achieve high loading and unloading efficiency and ensure safety. It is the main dry bulk cargo loading and unloading tool in ports. According to the types of goods handled, it can be divided into ore grab buckets, coal grab buckets, grain grab buckets, wood grab buckets, etc.
[0003] During the use of the grab bucket, during the process of the grab tip grabbing, it will rub against the ground. The grab buckets in daily use do not take corresponding countermeasures for this situation, resulting in the grab tip being worn after long-term use, thus reducing the working life of the grab tip during use and reducing the working efficiency of the grab bucket during use. Content of the Utility Model

The grab bucket bodies are mainly used for grabbing dry bulk goods, and a protection mechanism is provided at the bottom of the grab bucket bodies;
[0006] The protection mechanism includes a protection component and a fixing component. The protection component includes a plurality of grab tips fixedly connected to the bottoms of the two grab bucket bodies. At both ends of one side of the two grab bucket bodies, first fixing seats are fixedly connected. One side of each first fixing seat is rotatably connected to a movable rod. A first connecting rod is fixedly connected between every two opposite movable rods. A plurality of second connecting rods are rotatably connected to the outer walls of the two first connecting rods at equal distances.
[0007] In an example, a protective sleeve is sleeved on the outer wall of each grab tip. At both ends of one side of each protective sleeve, second fixing seats are fixedly connected, and the other end of the second connecting rod is rotatably connected to one side of the second fixing seat.
[0008] In one example, the outer wall of each of the grasping tips is covered with a protective sleeve, both ends of one side of each of the protective sleeves are fixedly connected to a second fixing seat, and the other end of the second connecting rod is rotatably connected to one side of the second fixing seat.
[0009] In one example, both ends of one side of each of the fixing blocks are fixedly connected to support plates, and one side of each of the support plates is provided with a groove.
[0010] In one example, the inner wall of each groove is slidably connected with a block, the bottom of each block is fixedly connected with a plurality of springs at equal distances, and the bottom of the spring is fixedly connected to the bottom of the inner wall of the groove.
[0011] The multi-petal grab bucket with a claw tip protection device proposed by the utility model can bring the following beneficial effects:
[0012] The multi-petal grab with a claw tip protection device is provided with a first fixed seat, a movable rod, a first connecting rod, a second connecting rod, a second fixed seat, and a protective sleeve arranged on one side of the grab body. When in use, before use, the protective sleeve is firstly put on the outside of the grab tip, and then the first connecting rod is bent upward so that the protective sleeve can be tightly put on the outside of the grab tip. The existence of the protective sleeve protects the grab tip during use, prevents the grab tip from being worn out under long-term use, and increases the service life of the grab tip during use.
[0013] The multi-petal grab with claw tip protection device has a fixing block, a circular groove, a support plate, a groove, a clamping block and a spring arranged on one side of the grab body. When the first connecting rod is swung to a certain position during use, the circular groove and the clamping block on one side of the grab body will fix the first connecting rod so that it can be firmly locked, which facilitates replacement and improves the practicability of the protective sleeve in protecting the claw tip.
