Embodiment Construction

[0031] Such as figure 1 — Figure 4 As shown, the present invention is a self-propelled coal sawing machine that longitudinally cuts the coal seam into lump coal, including a traveling mechanism 1, an operating mechanism 2, a guiding mechanism 3 and an executing mechanism 4, and the operating mechanism 2 is arranged on the traveling mechanism 1. The operating mechanism 2 can reciprocate and rotate 360° on the walking mechanism 1. The guiding mechanism 3 is hinged on the operating mechanism 2. The guiding mechanism 3 can be stretched out or retracted according to whether it is working. The actuator 4 is movable on the guiding mechanism 3. , the actuator 4 can reciprocate up and down along the guide mechanism 3;

[0032] The structure of the executive mechanism 3 is: comprising a driving device 5 and a milling machine driving head 6, the driving device 5 is movably arranged on the guide mechanism 3, the driving device 5 bottom is hinged with a milling machine driving head 6, th...

Abstract

The invention discloses a self-propelled coal sawing machine for longitudinally cutting a coal bed into block coal and a cutting method for cutting the coal bed by using the machine, belonging to the technical field of coal-mining of opencast coal mines. In order to overcome defects in the prior art, the invention provides a self-propelled coal sawing machine for longitudinally cutting a coal bed into block coal and a cutting method for cutting the coal bed by using the machine, which are capable of greatly improving a block forming rate, mining efficiency as well as economic value of the coal mining, and a cutting method thereof. In order to solve the technical problems, According to the technical scheme adopted by the invention, the self-propelled coal sawing machine for longitudinally cutting the coal bed into block coal is characterized in that an operating mechanism is arranged on a travelling mechanism; the operating mechanism can rotate on the traveling mechanism by 360 degrees in a reciprocating manner; a guide mechanism is hinged on the operating mechanism; the guide mechanism can be stretched out or withdrawn according to a condition that whether the guide mechanism is worked or not; an executing mechanism is movably arranged on the guide mechanism; the executing mechanism can move up and down along the guide mechanism in the reciprocating manner. The method for cutting the coal bed by using the machine is also provided. The self-propelled coal sawing machine for longitudinally cutting the coal bed into block coal and the cutting method for cutting the coal bed by using the machine, disclosed by the invention, are mainly used for cutting an opencast coal bed.

Description

technical field [0001] The invention relates to a self-propelled coal sawing machine for longitudinally cutting a coal seam into lump coal and a cutting method thereof, belonging to the technical field of coal mining in open-pit coal mines. Background technique [0002] The price of lump coal of the same coal quality in coal products is much higher than that of pulverized coal. At present, the coal industry is in a downturn, and increasing the yield of lump coal is crucial to improving the efficiency of coal mines. At present, the equipment and technology with large output have caused the coal agglomeration rate to be too low; the mining efficiency of equipment and technology with relatively high agglomeration rate is too low, and the operation is cumbersome. In short, the coal agglomeration rate is low, reducing the value of coal . Contents of the invention [0003] The invention overcomes the deficiencies in the prior art, and provides a self-propelled coal sawing machi...
