Subaerial comprehensive winning machine

Abstract

The invention provides a subbaerial comprehensive winning machine, comprising a winning mechanism, a winning mechanism stretching hydraulic device, a wining mechanism hydraulic lifting device, a loading bucket, a stable hydraulic strut, a drag conveyer, a travelling mechanism, a belt conveyer, a belt conveyer rotary lifting mechanism and a main engine frame. For the subbaerial comprehensive winning machine in the invention, the direction and the height of the winning mechanism can be regulated according to the condition of coal rake, the height of the belt conveyer can be regulated according to actual conditions, the belt conveyer can rotate left and right to realize continuous large-range coal extraction transportation, as the spacing of the abreast cutting mechanisms are smaller and more uniform, the particle size of the extracted coal is smaller and more uniform, thus avoiding drilling and blasting, omitting secondary crushing and shipping, operating in serialization, greatly improving comprehensive mechanical degree and coal winning working efficiency, reducing labor intensity and further lowering production cost of subbaerial coal extraction.

Description

technical field [0001] The invention relates to an open-pit comprehensive coal shearer, in particular to an efficient, safe and mechanized open-pit comprehensive coal shearer, which belongs to the technical field of mining equipment. Background technique [0002] At present, the open-pit mining process generally adopts drilling and blasting, and then uses excavators or electric shovels to excavate, load and transport the process, which not only has low production efficiency and high labor intensity, but also the volume of the mined coal is different, and it needs to be carried out many times. Only by crushing can the granularity required for use be achieved, which increases the cost per ton of coal. In addition, a coal cutter newly introduced from abroad has relatively small coal mining height and width, high power and low efficiency, and it is difficult to meet the needs of open-pit mine production. Developing key technologies and equipment for high-yield and high-efficien...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of low coal mining efficiency and the uneven size of the mined coal in the traditional open-pit coal mining process, which needs to be crushed multiple times. The front end of the machine can move up and down, far and near while rotating. The thickness of the cutting coal seam is large, the particle size of the coal block is small and uniform, the maintenance cost is low and convenient, the degree of comprehensive mechanization is high, safe and efficient, and the labor intensity is low. Drilling and blasting can be avoided. , Secondary crushing and shipment, the surface comprehensive coal mining machine that can realize continuous mining operations
