Coal-mine-based adjustable equal-distance drilling device for solidified coal

Abstract

The invention discloses a coal-mine-based adjustable equal-distance drilling device for solidified coal, relates to the technical field of coal briquette processing, and solve the problems that existing drilling devices mainly drill coal briquettes through fixed drilling structures, are relatively low in drilling efficiency and cannot quickly adjust the drilling distances of the drilling structures as required. The coal-mine-based adjustable equal-distance drilling device for the solidified coal comprises a coal briquette frame; a fixing plate is fixedly arranged in the middle of the coal briquette frame; an adjusting rod is rotationally arranged in the middle of the fixing plate; and a coal seat is fixedly arranged at the top of the adjusting rod and further comprises a self-locking block. A main rotating shaft and an auxiliary rotating shaft are arranged, the equal-distance synchronous drilling function is provided for a drilling rotating shaft, the main rotating shaft can cooperatewith a telescopic connecting shaft to drive the auxiliary rotating shaft to rotate in the same direction, the coal briquettes are drilled quickly, the drilling efficiency is high, and uniform drillingis realized.

Description

technical field [0001] The invention relates to the technical field of coal block processing, in particular to a coal mine-based adjustable equidistant drilling device for solidified coal. Background technique [0002] Honeycomb coal is a large honeycomb-shaped coal block that is burned as fuel in a honeycomb coal furnace. It is the main household fuel for many residents in East Asia; at present, according to the needs of the environment, honeycomb coal is gradually replaced by anthracite, and anthracite is integrated. With honeycomb coal furnace, it is necessary to use drilling equipment to drill holes in the center of the anthracite coal in order to fill the anthracite coal. [0003] After retrieval, for example, the patent No. CN105945323A discloses a drilling machine with an automatically adjustable center distance. Including the machine table, the upper part of the machine table is equipped with a tool holder; the tool holder is equipped with a drill bit, the tool hold...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a kind of adjustable equidistant drilling device based on solidified coal in coal mines, to solve the problem that the currently used drilling device proposed in the above-mentioned background technology mainly drills coal blocks through a fixed drilling structure, The drilling efficiency is slow, and the drilling spacing of the drilling structure cannot be adjusted quickly according to the needs, and the spacing cannot be adjusted synchronously according to the type of coal block, which is not conducive to the problem of rapid drilling of coal blocks
