Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] figure 1 A structural schematic diagram of an embodiment of the hinge mechanism of the present invention is given. The hinge mechanism 400 of the embodiment of the present invention is mainly used in an excavator, and usually the excavator includes: a fuselage 100 (ie, the cab, as the main body of operation control), and a boom 200 connect...

Abstract

The embodiment of the present invention relates to the field of engineering machinery technology, and provides an excavator, which includes a fuselage, a boom arranged on the fuselage, a bucket mechanism connected to the boom, and a hinge mechanism. The hinge mechanism It includes a first hydraulic swing cylinder arranged on the arm of the excavator, and a hinge shaft connected with the rotor of the first hydraulic swing cylinder and swinging left and right with the rotation of the rotor. In the excavator provided by the embodiment of the present invention, the hinge mechanism is applied to the boom of the excavator, and the left and right rotation of the boom is replaced by a structure in which the first hydraulic swing cylinder drives the hinge shaft to swing left and right, so as to avoid frequent rotation of the fuselage, thereby solving the problem of The fatigue problem of the driver in the cab can improve the operation quality and efficiency; the second hydraulic swing cylinder drives the bucket mechanism to move up and down, and the rotation range is larger than that of the traditional excavator, which improves the maximum working space of the excavator.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of engineering machinery, and in particular to an excavator. Background technique [0002] Excavators are widely used in municipal, transportation, farmland, water conservancy and modern military engineering and other fields, and are a major fortification equipment. Existing excavators are mainly driven by linear oil cylinders and other auxiliary mechanisms. Their structures largely limit the maximum working space and flexibility. However, frequent rotation will inevitably increase the fatigue of the driver, which will greatly affect the quality of work and work efficiency. Contents of the invention [0003] An embodiment of the present invention provides an excavator, which is used to solve the problem in the prior art that the driver's cab of the traditional excavator needs to rotate frequently during operation and cause driving fatigue, so as to improve the operation quality a...
