Abstract

The invention provides an excavator and a bucket tooth connection structure of the excavator. The excavator and the bucket tooth connection structure of the excavator are used for solving the problems that the bucket tooth connection structure is difficult to detach, and a connecting part is easy to damage. The bucket tooth connection structure comprises a bucket tooth, a tooth seat, a spring and a connecting pin, wherein the bucket tooth comprises a first installation hole and is provided with a placed-in groove and a locating groove, the tooth seat is provided with a second installation hole, the spring is arranged in the second installation hole, the connecting pin is provided with a protruding locating key, the bucket tooth is connected with the tooth seat, the locating key penetrates through the placed-in groove, the connecting pin is inserted to the first installation hole and the second installation hole, and the spring is arranged on the connecting pin in a penetrating mode. The excavator and the bucket tooth connection structure of the excavator have the advantages that the locating key can be enabled to break away from the locating groove, and the connecting pin is enabled to exit through the placed-in groove of the bucket tooth so that the bucket tooth and the tooth seat are enabled to be separated. Therefore, an assembly-disassembly process of the bucket tooth and the tooth seat is easy and simple, and the connecting part can not be damaged.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an excavator and a bucket tooth connection structure thereof. Background technique [0002] Excavator is a kind of construction machinery, which is widely used in construction, road, mine and other engineering fields, and its main function is to carry out excavation operations. [0003] figure 1 It is an outline structure diagram of an excavator in the prior art. As shown in the figure, the working part of the excavator mainly includes a bucket (bucket) 110, an arm (arm) 120 and a boom (boom) 130. Under the action, each component swings around the hinge point to complete actions such as digging, lifting and unloading soil. [0004] Usually, in the tooth connection of the bucket 110 of an excavator in the existing structure, a connecting pin and a locking washer are used to fix the bucket teeth to the tooth seat. figure 2 It is a partial structural schematic diag...
