A loading excavator

Abstract

The invention discloses a loading and evacuation integrated machine which comprises a travelling device, an operation room, an excavator device, a loader device, an engine and a high pressure oil pump. A central rotary oil-gas separation electret is arranged below the operation room and composed of a rotary shell, a fixing mandrel and a collecting ring. A shell of the collecting ring is fixedly connected with the rotary shell through bolts. A mandrel of the collecting ring is fixedly connected with the fixing mandrel. A frame comprises a front frame body and a rear frame body which are connected through a hinge. Two steering hydraulic cylinders are symmetrically arranged between the front frame body and the rear frame body. According to the loading and excavation integrated machine, by adoption of the technical scheme, 360-degree rotation of an excavator can be achieved, and all the functions of a loader can be combined; and by adoption of the hinge type hydraulic cylinder steering structure, it is ensured that driving force and resistance are in the same straight line during loading turning, the driving force can be used for maximally overcoming the resistance, and the work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of engineering machinery, in particular to excavators and loaders. Background technique [0002] Most of the existing construction machinery has a single function, and many construction sites require loaders and excavators to work at the same time. In the case of limited space, entering more construction vehicles at the same time will cause the site to be too crowded and cannot be constructed normally. There is a need for a construction machine that can simultaneously function as a loader and an excavator. The rotation between the excavator device and the vehicle frame of the existing loading excavator (i.e. two busy ends) can only turn 180°, which limits the working capacity of the excavator. And when the existing excavator turns, because the vehicle frame is one, only the wheels rotate, and when the excavator is turned under load, the loading direction and the driving force are at a certain angle, causing a part of...

Problems solved by technology

[0002] Most of the existing construction machinery has a single function, and many construction sites require loaders and excavators to work at the same time. In the case of limited space, entering more construction vehicles at the same time will cause the site to be too crowded and cannot be constructed normally. Need a kind of construction machine that can have loader and excavator function at the same time

The rotation between the excavator device and the frame of the existing loading excavator (that is, two busy ends) can only be rotated by 180°, which limits the working capacity of the excavator

And when the existing excavator turns, because the vehicle frame is integrated, only the wheels rotate, so that when the excavator turns under load, the loading direction and the driving force are at a certain angle, causing a part of the driving force to do useless work and resistance.
