mining backhoe loader

Abstract

The invention discloses a mining loader-digger. The mining loader-digger comprises a traveling mechanism, a digging mechanism, a conveying mechanism, a driving assembly, a hydraulic assembly, and an electrical assembly, which are all moveably connected with one another, wherein the digging mechanism, the conveying mechanism, a driving cabinet, the hydraulic assembly and the electrical assembly are supported by a chassis of the traveling mechanism and move together as the chassis moves. According to the mining loader-digger, by means of coordination and cooperation of the traveling mechanism, the digging mechanism, the conveying mechanism, the hydraulic assembly, and the electrical assembly, specified actions can be finally implemented by hydraulic and electrical actuators, and a mechanical transmission mechanism, and then various operation processes can be completed.

Description

technical field [0001] The invention belongs to the technical field of excavating loaders, in particular to a mining excavating loader. Background technique [0002] It is known that along with the extensive application of excavating conveyors in roads, construction and mining, China has become the world's largest country in the production and consumption of excavators; and the excavators currently in use mostly use internal combustion engines as drives, and during construction work Not only the noise is high, the energy consumption is high, and the environment is polluted, but also its cost is very high; in addition to its large size, it is difficult or even impossible to construct in a narrow space. Although there are currently small excavating conveyors that can Construction in a small area, but because the width of its fuselage is set to 1750mm, it still cannot minimize the construction area, so that it is still impossible to carry out mechanical construction in some nar...

[0002] It is known that along with the extensive application of excavating conveyors in roads, construction and mining, China has become the world's largest country in the production and consumption of excavators; and the excavators currently in use mostly use internal combustion engines as drives, and during construction work Not only the noise is high, the energy consumption is high, and the environment is polluted, but also its cost is very high; in addition to its large size, it is difficult or even impossible to construct in a narrow space. Although there are currently small excavating conveyors that can Construction in a small area, but because the width of its fuselage is set to 1750mm, it still cannot minimize the construction area, so that it is still impossible to carry out mechanical construction in some narrow mines and tunnels; at the same time, these small During the construction, the digging conveyor transports the excavated materials through multiple sets of concave transmission shafts to support and drive the conveyor belt to convey the materials. Each set of concave transmission shafts is composed of three transmission shafts, because the transmission shaft acts as a load-bearing support And the function of conveying materials, so it is easy to be damaged when the construction time is long, and this kind of sunken transmission shaft is very inconvenient to operate during installation, maintenance, disassembly and replacement, because when there is a problem with a set of sunken transmission shafts, it needs to be dealt with Three transmission shafts are a waste of time in installation and disassembly, and the conveyor belt supported by such transmission shafts can only make the loaded materials accumulate upward through the middle part, that is, △-shaped accumulation to obtain more In this way, it is inevitable that the material will be scattered along the two sides of the conveyor belt. At the same time, the loading amount of the material cannot be increased sufficiently, resulting in the construction area being dirty and the transmission efficiency is extremely low. In severe cases Greatly affected the progress of the construction
