Abstract

The present invention provides a hydraulic rotary quick change adapter connector of an excavator-type shovel clamshell excavator which belongs to a quick change adapter connector of engineering machinery. The hydraulic rotary quick change adapter connector is composed of an upper eared plate coupling assembly, a rotary box body and a quick change device, the upper eared plate coupling assembly connects with a connecting rod and a small arm of an excavator; the quick change device connects with a down part of the rotary box body upper coupling assembly. The rotary box body is drove by a hydraulic slave motor, uses an electromagnetic valve for controlling the operating state, the rotary box body rotates 360 degree and drives the scraper bucket rotary movement which can obtain best dredging angle, and is convenient to operate. The adapter connector can rapid change different specialty clamshell excavator for increasing changing efficiency and reducing labour cost greatly; the clamshell excavator can realize 360 degree all-side rotary in working which increases and enlarges high efficiency and convenient working ability of the excavator-type shovel, can realize dredging with all-side and multi-angle, and increase working efficiency of the excavator-type shovel greatly.

Description

technical field [0001] The invention relates to a quick-change connector of construction machinery, in particular to a quick-change connector for excavator bucket hydraulic rotation. Background technique [0002] At present, the bucket of the excavator is directly connected to the connecting rod and arm of the excavator, and can only perform excavation in one direction. When the excavator is working on the field, it is necessary to constantly adjust the excavation position of the excavator to carry out effective excavation. , This will reduce the operating efficiency of the excavator, and at the same time increase the fuel consumption of the excavator and increase the operating cost. Contents of the invention [0003] The object of the present invention is to provide a kind of: excavator bucket can do 360 ° rotation hydraulic rotary quick-change connector of excavator bucket. [0004] The object of the present invention is achieved in this way: the hydraulic rotary quick-...
