Abstract
The utility model provides a built-in oil cylinder type big arm of a loader-digger. The built-in oil cylinder type big arm of the loader-digger comprises a big arm, a big arm hydrocylinder and a hydraulic oil rubber pipe. The big arm is in a box-shaped structure and is welded through plate groups. The lower end of the big arm is a big end, and the upper end of the big arm is a small end. The lower end of the big arm is provided with a lower hinge point which is connected with a big arm seat in a hinged mode. The big arm hydrocylinder is arranged in an inner cavity of the big arm. The cylinder body of the big arm hydrocylinder is connected with the big arm seat in a hinged mode. A piston rod is connected to the inner side of a box wall of the big arm. The hydraulic oil rubber pipe is also arranged in the inner cavity of the big arm. Due to the fact that the big arm hydrocylinder and the hydraulic oil rubber pipe are arranged in the inner cavity of the big arm, a protective cover is formed for the big arm hydrocylinder and the hydraulic oil rubber pipe, the big arm hydrocylinder is not prone to being scraped, touched and damaged, the hydraulic oil rubber pipe is sun-proof and aging-proof, and service life of the equipment is prolonged.
