Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, an excavator bucket structure with bucket teeth capable of being replaced at any time comprises a deformation shaft 3, wherein the deformation shaft 3 is rotatably connected to a bucket body, the deformation shaft 3 comprises a shaft body 31, a plurality of support rods 32 are alternately arranged on two sides of the shaft body 31, and each support rod 32 corresponds to a set of bucket tooth devices; the bucket tooth device comprises a bucket tooth 1 serving as a cutting component and a fixed block 2 connected to the bucket body in a sliding mode, and the bucket tooth 1 and the fixed block 2 are detachably and fixedly connected; the deformation shaft 3 adjusts the position relation between the two side support rods 32 and the bucket tooth device through rotation, and then controls the bucket teeth 1 on the bucket tooth device to alternately extend out of the bucket body.
