Description
Technical field
The present invention relates to a kind of digger, and particularly, but not exclusively, relate to a kind of continuous digger of anchor pole with the rotary cutting head being installed in cutting suspension rod place, wherein, the driver part for rotary cutting head is arranged on the region place of cutting suspension rod.
Background technology
Multiple diverse ways and machine are developed to take out mineral and other valuable material under the earth's surface place and earth's surface of the earth.This machine runs usually in very dark mine.
In order to maximize driving and mineral organic efficiency, develop the digger for specific purpose.Some machines are constructed in order to specially from deposit layer or ore bed cutting mineral, and other machine is constructed in order to tunneling in subterranean depth, effectively to produce mine and to be provided for the passage of mineral cutter.Especially, mobile digger occurs as successful equipment, in order to provide direct cutting at ore bed place, and as the measure of quick tunnelling.Usually, mobile digger comprises rotatable or digging head, and it has setting drill bit on a rotating drum, with contact mineral face.Usually, cutting head is installed in movable lever davit place, can regulate height relative at the bottom of tunnel.Along with cutting head rotate and advance in ore bed, the mineral taken out are harrowed pawl (gathering head) and are collected, and are then moved machine and carry backward via conveying equipment, with produce for subsequently from mining site take out discharge stockpile.
Usually the rotation of cutting head is driven by electro-motor, by gear assembly, from electro-motor transmission of drive force.Usually, electro-motor is disposed coaxially in the cutting head of elongation.This layout makes to need a kind of quite complicated gear assembly, and wherein many group planetary gears are around central gear and driving shaft orbital motion.In GB 2476575, WO 00/36230, US 4,047,763 and GB 2018329, the example drive described for continuous digger is arranged.US 6,158,818 describes a kind of by Rock cutting head that is electronic or fluid motor-driven, and motor is attached to cutting head by axle and the gear assembly extending partially across center suspension rod, and wherein motor is arranged on the rear of cutting head by center suspension rod.But, should understand, complicated gear assembly and the complicated operation degree needing a large amount of seal and bearing to improve machine, and because this increasing the needs to regular maintenance and maintenance.The number of workpiece part also improves the risk of Parts Breakdown and the overall weight of machine.Therefore, a kind of driven unit for digger solved the problem is needed.
Summary of the invention
Target of the present invention is to provide a kind of digger, particularly a kind of like this driven unit for digger, it reduces the number of the component working part of the ingredient as system as much as possible, thus provides a kind of light weight, the efficient and drive transmission of the rotary cutting head for digger of strong operability.Another target of the present invention is that the region place be configured to by this driven unit at rotary cutting head takies minimum volume, not hinder tunnel top bolt support fitting machine (roof bolting rig) being immediately positioned at cutting head rear, thus realize the tunnel top bolt support of next-door neighbour's cut surface.
These targets are realized by providing a kind of driving mechanism being arranged on one end place of cutting suspension rod rotary cutting head being arranged on digger place.Especially, cutting suspension rod preferably includes roughly T-shaped structure, and the base portion of ' T ' is attached to digger pivotly, and motor and gear case assembly are arranged on two upsides and the lateral arms place of ' T ' respectively.Especially, the first arm place that motor is arranged on ' T ', or be preferably accommodated in first arm of ' T ', and gear-box is accommodated in second arm of ' T ' with the driver part be associated.The driving shaft extended extends to gear-box from motor between the arms, and the main length being approximately perpendicular to cutting suspension rod is aimed at.Via the one or more gear carriers extending to rotary cutting head from boom arms, driving force is passed to rotary cutting head.
Preferably, cutting machine motor is electronic.Alternately, cutting machine motor can be hydraulic motor.Preferably, cutting machine motor parallel is aimed in the main shaft of rotary cutting head, and this is for minimizing space that motor takies and allowing to drive transmission to be all favourable efficiently.Advantageously, motor and gear-box are accommodated in the end of cutting machine suspension rod, to be immediately arranged on the rear of swivel head.When there is any mechanical problem of associated motor and/or gear-box, keep in repair or safeguard that axis is relatively direct relative to the layout of routine especially, in routine is arranged, these parts are arranged in cutting head integratedly.In addition, avoid and need complicated many groups planetary gear, bearing and seal, thus provide one simply too much, sturdy and durable and drive structure more reliably.
The other favourable part of layout of the present invention is, needs operation single-motor and gear-box with to whole cutting head supply driving force.Therefore, structure of the present invention is provided convenience to use and is better than the conventional higher power motor arranged, conventional layout may comprise the independent motor of two of being accommodated in cutting head, and these two motors have the size that the useful size by the inside of cutting head limits.
According to a first aspect of the invention, provide a kind of digger taking out material from deposit layer, this digger comprises: main frame; Cutting suspension rod, this cutting suspension rod is pivotably mounted on main frame place towards first end; Cutting head, it is rotatably installed in the second end place of cutting suspension rod, and suspension rod can raise relative to main frame and reduce cutting head; Cutting head motor, in order to drive the rotation of cutting head; And gear assembly, this gear assembly can be connected between motor and cutting head with driving, so that power is passed to cutting head from motor; It is characterized in that: this digger comprises driving the single-motor of the rotation of cutting head, this single-motor is arranged on the first side place of suspension rod at the second end place immediately preceding the rear of cutting head; And gear assembly is arranged on the second side place of suspension rod at the second end place immediately preceding the rear of cutting head, at least one driving shaft can be connected between motor and gear assembly with driving.
