[0002] A bucket refers to a bucket-shaped component used for excavating loose materials such as soil, yellow sand, gravel, and construction waste. It is composed of a bottom plate, wall plates, hanging ear plates, ear plates, tooth plates, side plates, bucket teeth, side teeth, etc. It is a working device often installed on an excavator for excavation. After the bucket is used for a long time, its bucket teeth are prone to damage, and at this time, the bucket teeth need to be replaced.

[0003] In the existing technology, the bucket teeth and the bucket tooth seat are locked and connected by a thick pin. However, the pin itself is prone to deformation under the long-term high pressure of the bucket teeth. In this state, it is necessary to use a hammer to knock out the pin, and then after replacing the new bucket teeth, it is also necessary to use a hammer to reset the pin, which is time-consuming and laborious.

[0009] Preferably, a U-shaped groove is arranged on the bucket tooth seat, the shovel plate is inserted into the U-shaped groove, and the bucket tooth seat and the shovel plate are integrally welded, and the distances between the bucket tooth seats are equal.

[0010] Preferably, a limiting column is arranged at one end of the bucket tooth seat close to the bucket teeth, two clamping grooves symmetrical about the limiting column are arranged on the bucket tooth seat, a limiting hole is arranged at one end of the bucket teeth close to the bucket tooth seat, two clamping blocks symmetrical about the limiting hole are arranged on the bucket teeth, the clamping blocks are inserted into the clamping grooves and slidably connected together, and the limiting column is inserted into the limiting hole and slidably connected with it.

[0011] Preferably, a cavity is arranged inside the rotating shaft. The button is located inside the cavity and is elastically and slidably connected thereto. A non-cylindrical through hole is arranged inside the rotating shaft. The non-cylindrical through hole communicates with the cavity. The sliding rod is located inside the non-cylindrical through hole and fits against its inner wall, and the sliding rod is slidably connected to the non-cylindrical through hole. The sliding rod is inserted into the cavity and connected to the button.

[0012] Preferably, a spring is arranged inside the cavity. A solid rod is arranged on the button. The solid rod is connected to the sliding rod. The spring is sleeved outside the solid rod. Two ends of the spring respectively abut against the button and the inner wall of the cavity.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] By arranging a hook on the tooth socket of the bucket tooth and a convex post on the bucket tooth, after the bucket tooth is inserted into the tooth socket of the bucket tooth, the hook can be flipped to limit the sliding of the bucket tooth, preventing the bucket tooth from falling off during operation, and this structure improves the efficiency of replacing the bucket tooth. By arranging an elastically sliding button inside the rotating shaft, the button is connected to the sliding rod, the sliding rod is connected to the tooth block, and the tooth block is located in the tooth groove. When it is necessary to release the rotational restriction on the hook, only need to press the button to push the tooth block away from the tooth groove. After the hook is stuck on the convex post, just let go, the button automatically rebounds and drives the tooth block to automatically snap into the tooth groove to complete the restriction on the rotation of the hook, avoiding hard debris pushing the hook away from the convex post during the excavation work and causing the bucket tooth to fall off. The whole structure is simple, and the operation of replacing the bucket tooth is convenient and fast. Description of the Drawings
