Abstract
The utility model discloses a roadheader cutting device which belongs to the technical filed of roadheaders and is mainly suitable for rigid rock drift tunneling. The roadheader cutting device comprises a cutting arm, a speed reducer, a motor and a cutting rotary drum, wherein the cutting rotary drum is provided with at least two rows of hobbing cutters. The cutting arm is put downwards to be in a proper position, the motor is started, the speed reducer drives the cutting rotary drum to move, and the hobbing cutters are installed on the cutting rotary drum and used for cutting rocks. The roadheader cutting device has the following beneficial effects: the hobbing cutters installed on the cutting rotary drum are used for breaking the rocks, and are suitable for rigid rock drift construction with the rock rigidity being more than 10 as the hobbing cutters have large rigidity, the rock breaking efficiency is high, and the abrasion is less.
Description
Technical field
The utility model relates to a kind of fully-mechanized digging machine, is specifically related to a kind of fully-mechanized digging machine cutting means, is applicable to the fully-mechanized digging machine cutting means of hard rock tunnelling.
Background technology
The comprehensive mechanized development machines that adopt of capital construction mine laneway construction at present, multiple functions such as comprehensive mechanized development machine collection driving, muck, fortune coal, supporting are one, have improved tunnelling speed greatly more.Comprehensive mechanized development machine generally is made up of cutting units, shovel board, Department of Transportation, body, running part, back supporting, hydraulic system, water system, lubricating system, electrical system 10 parts.Wherein, cutting units is made up of cutterhead, pars contractilis, reductor, motor, is welded with pick on the cutterhead.Make cutterhead flexible through pars contractilis, thereby utilize pick to break rock.Because there are problems such as pick insufficient rigidity, so though comprehensive mechanized development machine effect in full coal petrography, alternate heading is good at present, and in the hard rock tunnel, the pick wearing and tearing are bigger, cause drivage efficiency not high.
Summary of the invention
The purpose of the utility model is to provide a kind of fully-mechanized digging machine cutting means that is applicable to hard rock tunnelling construction, mainly is the improvement to the comprehensive mechanized development machine cutting means.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is following: a kind of fully-mechanized digging machine cutting means, it comprises cutting arm, reductor, motor, cutting drum, and at least two row's hobboing cutters are housed on described cutting drum.The position that hobboing cutter is installed on described cutting drum is welded with junction plate, and described hobboing cutter is installed on the bearing at cutter shaft two ends through cutter shaft; Described bearing is welded on the junction plate.The quantity of hobboing cutter is provided with as required.
The beneficial effect of the utility model is that this cutting means breaks rock through the hobboing cutter that is installed on the cutting drum, and hobboing cutter rigidity is big, and wearing and tearing are few, applicable to formation hardness greater than 10 hard rock roadway construction.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the hobboing cutter scheme of installation.
Among the figure: 1, cutting arm, 2, reductor, 3, motor, 4, cutting drum, 5, hobboing cutter, 6, cutter shaft, 7, cutter bearing, 8, junction plate, 9, baffle plate.
The specific embodiment
As shown in Figure 1, a kind of fully-mechanized digging machine cutting means is made up of cutting arm 1, reductor 2, motor 3, cutting drum 4: two row's hobboing cutters 5 are housed on cutting drum 4.Hobboing cutter quantity and arrangement are confirmed according to cutting drum diameter and institute's construction tunnel formation hardness.Described hobboing cutter 5 is the disc hobboing cutter.
As shown in Figure 2, the position that hobboing cutter is installed on cutting drum 4 is welded with junction plate 8, and described hobboing cutter is installed on the bearing 7 at cutter shaft 6 two ends through cutter shaft 6, and bearing 7 is welded on the junction plate 8.For preventing that rock fragment from getting in the cutting drum 4, in cutting drum 4 inboards baffle plate 9 is housed, baffle plate 9 is welded on cutting drum 4 inboards.
Cutting opening in hobboing cutter place is installed on cutting drum 4, is welded to connect plate 8.Junction plate 8 be by two block plates be welded into rectangular-shaped, horizontal steel plate is welded on the cylinder, vertical steel plate stretches in the cylinder.Bearing 7 is welded on the vertical junction plate, and highest point is concordant with horizontal connecting plate.
Cutting arm 1 is lowered into correct position, and then, motor 3 starts, and drives cutting drums 4 motions through reductor 2, and hobboing cutter 5 is installed on the cutting drum 4, because hobboing cutter rigidity is big, can be used for cutting hardness greater than 10 hard rock.
Claims (5)
