Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and figure 2 As shown, a side-side mining drilling rig in an open-pit coal mine includes a local machine assembly 4 installed with a crawler belt assembly 3 to facilitate the overall movement of the local machine assembly 4 . The machine assembly 4 includes: an engine assembly 8, a fuel oil tank 6 used in conjunction with the engine assembly 8; a shed 10 located on the top of the machine assembly 4, and a shed 10 between the shed 10 and the track assembly. Into the cab 11 between the 3; the engine assembly 8 provides power for the movement. The inner top of the scaffold 10 is provided with a hoist drill changing assembly 9; the drill tool assembly 12 installed and disassembled is replaced by the hoist drill changing assembly 9. Moreover, a coal drill bit is provided at the end of the first root of the drill...

Abstract

The invention discloses an open-pit coal mine end slope drilling rig. The open-pit coal mine end slope drilling rig comprises a crawler assembly and a local assembly; the local assembly comprises a shed frame and a winch drilling replacement assembly; a front vise assembly and a power head assembly are separately arranged in the front and rear directions of the bottom of the local assembly; the front vise assembly and the power head assembly are connected to a drilling tool assembly with spiral blades on the outer surface in a driving manner; a conveyor belt assembly is arranged below the rearends of the front vise assembly, the power head assembly and the local assembly; and a shovel plate assembly and a rear support assembly driven by a hydraulic cylinder to swing up and down are separately hinged to the front end and the rear end below the local assembly. The open-pit coal mine end slope drilling rig has the advantages that through the coordination of multiple systems, the effectsof automatic replacement of drilling tools and automatic drilling are achieved.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a drill truck for side-side mining in an open-pit coal mine. Background technique [0002] A large proportion of my country's open-pit coal mines are located in slippery areas, and the slope design is gentle. At the same time, the depth of coal seams is large, and the range of mine fields is wide, which leads to a large number of end-side coal resources in open-pit coal mines. The end-side coal mining technology is a technology that uses the exposed coal seam of the open-pit coal mine stope to arrange coal mining equipment for raw coal mining. It does not need to be stripped separately. It has the characteristics of low cost of coal resource mining, high production efficiency, and no ground subsidence. It is of great significance to improve the recovery rate of coal resources in my country's mining industry and enhance the economic benefits of coal enterprises. However, at present...
