Dredger

Abstract

The invention discloses a dredger. The dredger comprises a dredger body, a main control table mechanism, a working mechanism and a walking mechanism. A cab, an operation table, a power device, a crawler, a guide wheel, a drive wheel, a rotary device, a movable arm, a movable arm oil cylinder, a bucket column, a bucket column oil cylinder, a bucket oil cylinder, a bucket oil cylinder fixing groove,a rocking rod, a connecting rod, a rocking rod fixing groove, a universal positioning device, bayonet devices, a bucket and an rescue device. The dredger is reasonable in design, through the cooperation of the bucket oil cylinder fixing groove, the rocking rod fixing groove, the universal positioning device and the bayonet devices, the problems that an existing dredger works in narrow space difficultly, and is low in efficiency are successfully solved, and the rescue device is arranged, so that the dredger has a self-rescue function in severe environments.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to a dredger. Background technique [0002] A dredger, also known as an excavator, is a machine that uses a bucket to excavate materials above or below the bearing surface and load it into a transport vehicle or unload it to a stockyard. Dredgers are mainly used for engineering construction, such as: roads, breeding ponds, underground engineering, emergency excavation and so on. The main feature of the dredger is that it is powerful and can complete projects that cannot be completed by manpower. However, in some special occasions such as underground construction, due to the limited activity space due to environmental restrictions, the materials cannot be easily shoveled out, and the entire fuselage needs to be adjusted before the operation. The whole process is cumbersome and wastes manpower and energy consumption, and the efficiency is also low. [0003] It is difficul...

AI Technical Summary

Problems solved by technology

However, in some special occasions such as underground construction, due to the limited activity space due to environmental restrictions, the materials cannot be easily shoveled out, and the entire fuselage needs to be adjusted before operation. The whole process is cumbersome and wastes manpower and energy consumption, and the efficiency is also low.

[0003] It is difficult to walk on some complex ground, and other sundries are easily embedded in the track, causing jamming. It is difficult for the operator alone to return to normal, and other help is needed
