Definitions
- the invention relates to a shearer loader for mining extraction in longwall construction, with one along a longwall conveyor in the longitudinal direction movable machine body and at least two themselves in their Cutting profile complementary or overlapping cutting rollers.
- Such shearer loaders are usually equipped with two horizontal rollers, whose axes of rotation parallel to the slope and perpendicular to the excavation run, the cutting profiles of two in the direction of Extraction drive of the cutting rollers lying one behind the other in this way supplement or overlap that the upcoming prize at a Passage of the shearer loader is won.
- Cross-conveying is often an obstacle to the performance of this type of rotary cutter loader of the cut material to be cut parallel to the direction of travel running face conveyor.
- the cut material must be cut namely one that runs transverse to the direction of travel of the extraction machine Movement components are forced.
- the cutting tools on the circumference of the cutting rollers on helically running Arrange the aisles that are necessary for the cut extraction material To give movement components in the direction of the conveyor.
- the invention relates to a shearer loader for mining Extraction in longwall construction, with one along a longwall conveyor in Longitudinal direction movable machine body and at least two in their cutting profile complementary or overlapping cutting rollers, thereby characterized in that a cutting roller parallel to the slope extending axis of rotation is arranged and as a horizontal roller for Free cutting of the hanging and another cutting roller with is arranged perpendicular to the horizontal axis of rotation and as Vertical roller is used to cut the lying surface, the horizontal roller is arranged above and in the direction of extraction in front of the vertical roller.
- the in Horizontal roller leading in the direction of the extraction run in a known manner and a collapse into the mining front that exposes the slope.
- the material extracted from the leading horizontal roller falls thereby on the vertical roller working below and behind, which the Extraction goods by their rotating movement towards the Face conveyor granted movement component.
- it cuts Vertical roller loosens the pending material to the lying position.
- the is Support arm carrying vertical roller in the one of the leading one Horizontal roller cut space so that this arm - unlike the State of the art - cannot hinder extraction work.
- both on the horizontal roller and on the Vertical roller the cutting tools are arranged so that the Cutting the material to be extracted runs optimally.
- An advantageous embodiment of the invention provides that the horizontal roller and the vertical roller as well as their drive motors and gears on one common supporting structure are attached. This results in a particularly compact design of this new cutting roller combination including Drive.
- the horizontal roller and / or the vertical roller in can be mounted at different heights in relation to the supporting structure are.
- the Overlap area of both cutting profiles can be set differently, so that total thicknesses that can be cut differently result. The The greatest possible thickness is achieved when both cutting profiles are straight still touch.
- the Support structure in its entirety in relation to the machine body is adjustable in height. This can, if necessary, of Roller cutter loader cut free area following the course of the seam be raised or lowered.
- the desired height adjustability will best accomplished by the common supporting structure around a pivot axis running perpendicular to the excavation joint the machine body is mounted. It is useful for pivoting a hydraulic cylinder between the machine body and the common Supporting structure. By retracting and extending this hydraulic cylinder, the common support structure of horizontal roller and vertical roller easiest way to raise and lower.
- roller body of the vertical roller with radially extending carrier bars for the cross transport of the Horizontal roller loosened material is provided. These takeaways are conveniently located in the face of the vertical roller and take the extraction material cut from the horizontal roller to it throwing on the face conveyor.
- the axis of the horizontal roller with respect to the Dump is angled at an angle. This makes it possible to Support and shift the horizontal roller at both ends so that the otherwise usual one-sided mounting of the horizontal roller can be omitted.
- the machine body - only partially shown - with the Reference number 1 denotes.
- This machine body 1 is along one Longitudinal conveyor 2 can be moved, extending along the front 3 of a Striving for profit stretches.
- a joint 4 On the machine body 1 there is a joint 4 with a horizontal hinge axis, a supporting structure 5 is mounted.
- a Pressure cylinder 6 For pivoting the support structure 5 about the joint 4 is a Pressure cylinder 6 provided.
- the supporting structure 5 carries two cutting tools Cutting rollers, one of which is perpendicular to the horizontal 7 has extending axis of rotation and hereinafter referred to as vertical roller (8) while the other one is horizontal and parallel to the slope 9 has extending axis of rotation and hereinafter called horizontal roller 10 becomes.
- the horizontal roller 10 is in the direction of the winning trip (arrow x) Machine arranged in front of the vertical roller 8 and is used to cut the Hangenden 9.
- the vertical roller 8 is in the direction of the winning trip (arrow x) the machine behind the horizontal roller 10 and is used for Cut free the lying 7 and for the transport of the Horizontal roller 10 cut material to be extracted onto the face conveyor 2.
- this is a total pivotable support structure 5 is rigid in itself and has one rigid, extending over the vertical roller 8 first support arm 11 on the free end of the vertical roller 8 is mounted.
- a housing 12 is also mounted, which has a drive motor 13 for the Vertical roller 8 takes.
- the drive motor 13 and the vertical roller 8 are by one not shown in the drawing, by the arm 11 extending gear train connected.
- a clearing plow 14 is attached, the if necessary behind the vertical roller 8 remaining material to be extracted Face conveyor 2 pushes. Finally, the vertical roller 8 is still radial with itself extending driver webs 15 provided when rotating the Vertical roller 8 the removal of the material to be extracted on the face conveyor 2nd support.
- the support structure 5 in the embodiment according to the Figures 1 and 2 a rigid, laterally next to the horizontal roller 10th extending second rigid support arm 16, at the free end of the Horizontal roller 10 is mounted.
- the rigid support arm 16 continues to enter Housing 17, which has a drive motor 18 for the horizontal roller 10 receives.
- the drive motor 18 and the horizontal roller 10 are by an in the drawing, not shown in detail, through the support arm 16 extending gear train connected.
- the Horizontal roller 10 and the vertical roller 8 with the help of not closer shown aids can be mounted at different heights.
- each The traps complement or overlap the cutting profiles of the two Cutting rollers, however, such that the entire Aspirational strength from the hanging 9 to the lying 7 is gained.
- FIGS. 1 and 2 it cuts in the direction of travel leading horizontal roll 10 first an upper bank of the seam up to Hanging 9 free.
- the cut lottery is cut by the Rotation of the horizontal roller 10 in the working area of the vertical roller 8 promoted.
- the trailing vertical roller 8 then cuts the lower bench of the Seams up to the lying 7 free and promotes the cut loose Extraction material - together with the extraction material of the horizontal roller 10 - on the face conveyor 2.
- the cross-conveyance of the extraction material is carried out by the radially extending clearing webs 15 provided on the vertical roller 8 supported. Any remaining winnings will then be removed from the Clearing plow 14 pushed onto the face conveyor 2.
- the roller cutter loader according to FIGS. 3 and 4 corresponds in its essential parts of the embodiment of Figures 1 and 2, so that for the other corresponding components use the same reference numerals could become.
- the rigid bearing the horizontal roller 10 Support arm 16 replaced by a movable support arm 19 which by means of a Swivel cylinder 20 about a horizontal axis 21 on which the Vertical roller 8 supporting arm 11 is mounted.
- the axis of the horizontal roller 10 with respect to the Dismantling joint also run at an angle. In this case it is possible to shift the horizontal roller 10 on two support arms 16 or 19. This Variant is not shown in the drawing.
