Dust-falling wheel pick press-planing type combined mining machine for strip mine

Abstract

The invention provides a dust-falling wheel pick press-planing type combined mining machine for a strip mine, and belongs to the technical field of mining machinery. The dust-falling wheel pick press-planing type combined mining machine for the strip mine realizes continuous mining, loading and transporting, transferring and direct coal storage of a lignite strip mine with loose blasting, is lower in purchase cost, saves energy and reduces consumption, is beneficial to cost reduction and benefit increase, realizes green mining, and reduces environmental pollution. The dust-falling wheel pick press-planing type combined mining machine for the strip mine comprises a main machine platform, wherein a cab is arranged on the upper part of the main machine platform; and a travelling crawler belt is arranged on the lower part of the main machine platform. The dust-falling wheel pick press-planing type combined mining machine for the strip mine is characterized in that a planing and mining mechanism is hinged to the front upper part of the main machine platform; the planing and mining mechanism is connected with a lifting hydraulic oil cylinder and a pitching oil cylinder; the lifting hydraulic oil cylinder and the pitching oil cylinder are fixed on the main machine platform; a material receiving shovel mechanism is hinged to the front lower part of the main machine platform; the material receiving shovel mechanism is connected with a material shovel lifting oil cylinder; the material shovel lifting oil cylinder is fixed on the main machine platform; and a screening and transporting mechanism is connected to the material receiving shovel mechanism.

Description

technical field [0001] The invention belongs to the technical field of open-pit mine mining machinery, and in particular relates to an open-pit mine dust-suppressing wheel pick pressure-planing combined mining machine. Background technique [0002] At present, large-scale open-pit coal mines generally adopt the single-bucket-truck process system. Trucks are the gathering positions for workers in the transportation link. This link employs a large number of people and has many potential safety hazards. Tape transportation is the best alternative to mine truck transportation, although the initial investment is relatively high. , but energy saving, safety, less labor, low operating costs, easy to achieve remote control and unmanned intelligence, in line with the development requirements of modern open-pit mines. At present, the tape transportation is mostly used in the semi-continuous process system. On the basis of the single bucket-truck process system, it is changed to a sing...

Problems solved by technology

At present, the tape transportation is mostly used in the semi-continuous process system. On the basis of the single bucket-truck process system, it is changed to a single bucket-mobile crusher-reloader-belt system. The semi-continuous system must have a mobile crushing station, but the current domestic mobile crushing The mobile crushing station has not really passed the test, because the wheel bucket continuous process system of the mobile crushing station is well-equipped to excavate the Quaternary soft rock and soil layer on the topsoil steps, but its body is heavy and inflexible, the supporting links are complicated, the adaptability is weak, and the ability to adapt to the environment Poor (can only be placed on the upper steps of open-pit mines), so there are no engineering examples to replace electric shovels for deep step operations and hard rock blasting

Moreover, in the process of open-pit mining, a large amount of coal / rock dust will be produced, which will greatly pollute the environment and affect the health of workers
