Abstract

The invention discloses a rotary and quick connector for an excavator. The rotary and quick connector for the excavator comprises a swing actuator, an excavating arm connecting piece and an accessoryconnecting piece. The excavating arm connecting piece is fixedly connected with a cylinder body of the swing actuator, the accessory connecting piece is fixedly connected with the swing output shaft of the swing actuator, and the excavating arm connecting piece is connected with the bottom end of an excavating arm. The accessory connecting piece is hinged to a working accessory through an accessory connecting shaft, and the accessory connecting shaft is perpendicular to the swing output shaft of the swing actuator. The swing actuator can drive the working accessory to adjust the + / -90 degrees,when the swing angle of the working accessory is within the scope of + / -90 degrees, the oblique angle adjustment is realized, and thus the oblique excavation can be carried out, when the working accessory swings to the + / -90 degrees, the working accessory swings to in a horizontal position, and side and horizontal excavation can be carried out. The rotary and quick connector for the excavator canadjust the angle of the working accessory, so that the working accessory meets the requirements of excavation of different directions.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an excavator rotary quick connector. Background technique [0002] The excavator is known as the "King of Prominent Machinery", and its use has always been very extensive. Common applications include earthwork excavation, leveling and other operations. After replacing working tools such as breakers, hydraulic shears, and carpentry clamps, the scope of application is greatly expanded. According to incomplete statistics, there are more than 10,000 types of excavator working tools on the market. At present, in order to facilitate the rapid replacement of various work attachments by excavators on the market, quick connectors are used to install various work attachments on the bottom of the excavator's excavator arm. The quick connector can quickly install and switch various configuration work attributes. The tool greatly improves the working efficiency of the excavator. During excavation, ...
