Embodiment Construction

[0017] see Figure 1-Figure 3 , the bottom plate 1 of the excavator base of the present invention is a U-shaped structure with left and right upward warping edges, a central hole 15 is opened in the middle of the bottom plate 1, and a central cylinder 7 enclosing the central hole 15 is arranged outside the central hole 15. . A front leg bushing 13 is installed vertically on both sides of the front end of the base plate 1, and a rear leg bushing 2 is horizontally installed on both sides of the rear end of the bottom plate 1; Cylindrical structure with through holes. The periphery of the central cylinder 7 is enclosed by the rear baffle 5 of the fuel tank and the front baffle 22 of the fuel tank, and together with the bottom plate 1 forms a closed cavity—that is, the auxiliary fuel tank. The fuel tank rear baffle 5 is in a convex shape symmetrical to the axis, and the fuel tank front baffle 22 is in a concave shape symmetrical to the axis. . In the auxiliary fuel tank, there...

Abstract

The invention relates to an excavator base with an embedded auxiliary fuel tank. A central cylinder is arranged outside a central hole of the base; a closed cavity, namely the auxiliary fuel tank, is formed at the periphery of the central cylinder; the front part and the rear part of each side of a rear baffle plate of the fuel tank are respectively provided with a hole; the four holes are fuel pipe channels; each fuel pipe channel penetrates through the inner part and the outer part of the base and is communicated with a central hole in the central cylinder; and four fuel tank inner ribbed plates are distributed in the auxiliary fuel tank, so that the auxiliary fuel tank is divided into four small fuel tanks. The auxiliary fuel tank is added to the base, so that the independent and continuous working efficiency of an excavator is greatly improved; due to the design of the base, the gravity center of the excavator is lowered; the requirement of the excavator working under complicated terrain environment is met; and box-type structures are arranged on two sides of the base, so that the structural strength of the base is guaranteed, and the weight of the base is reduced.

Description

technical field [0001] The invention relates to a component of an engineering excavator, in particular to a base of the excavator, on which a built-in auxiliary fuel tank is provided. Background technique [0002] At present, from the perspective of chassis classification, excavators are divided into two categories: wheeled and crawler excavators, and their bases are generally composed of fixed frames and slewing bearings. As an important part of the excavator chassis, it provides fixation and support for the excavator on-board slewing platform, central slewing joint, off-board drive shaft and chassis walking system. The base of the existing category only plays the role of connection and support, and does not have a built-in fuel tank itself. Therefore, there are shortcomings such as short independent and continuous operation time of the excavator in the field, a relatively high center of gravity, and poor operating stability. Contents of the invention [0003] The prese...
