| description | An engineering machinery rotary work arm comprises a bucket rod and a drill rod and further comprises a connection device of the bucket rod and the drill rod. The engineering machinery rotary work arm is characterized in that the bucket rod and the drill rod are connected through the connection rod, and the connection rod enables the drill rod to rotate around the bucket rod. Specifically, the connection device comprises a first oil cylinder, a first rotary arm and a second rotary arm, wherein the first rotary arm and the second rotary arm are connected in a rotatable mode, the first oil cylinder is connected with the second rotary arm and the drill rod, the first rotary arm is connected with the second rotary arm in a rotatable mode, and the first rotary arm is connected with the drill rod in a rotatable mode. Due to a rotary connection structure between the drill rod and the bucket rod, the engineering machinery rotary work arm enlarges a work face of the drill rod, reduces operation intensity of an operato |
