Abstract

The invention provides an adjustable excavator connector and an excavator. The adjustable excavator connector comprises a bucket rod connecting module, an accessory connecting module, an opening adjusting mechanism and a middle retainer, wherein the bucket rod connecting module comprises at least two connecting pins, the accessory connecting module comprises a first supporting piece and a second supporting piece, the first supporting piece and the second supporting piece are arranged in parallel and are connected to the connecting pins in a sliding mode, the opening adjusting mechanism comprises a double-end stud, the thread directions of the two ends of the double-end stud are opposite, one end of the double-end stud is connected with the first supporting piece, the other end of the double-end stud is connected with the second supporting piece, the middle retainer is located between the first supporting piece and the second supporting piece and fixedly connected with the bucket rod connecting module, and the middle retainer is connected with the double-end stud to axially limit the double-end stud. According to the adjustable excavator connector and the excavator, the installation requirements of accessories with different opening sizes can be met by adjusting the opening sizes, and centering can be achieved in the adjusting process.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an adjustable excavator connector and an excavator. Background technique [0002] Excavators and other operating machinery play an important role in the field of construction machinery. During their use, different attachments can be used according to work requirements, such as buckets, grabs, breakers or lifting hooks. A quick connector for the connection between the excavator and different attachments came into being. This device can easily switch the working scene of the excavator and improve work efficiency. However, the same manufacturer may design different sizes for the opening parts when designing the attachments. In addition, the opening parts of the attachments designed by different manufacturers are also different in size, which causes certain troubles for users to choose attachments. [0003] Some existing quick connectors adjust and match the size of th...
