Abstract
The open a kind of clear device for coal of the utility model, the conveyer comprising 2 secondary hydraulic supports and be arranged between hydraulic support, described hydraulic support comprises hydraulic pressure after-frame and hydraulic pressure side arm, and the rear end of described hydraulic pressure after-frame is connected with paw unit by passing oil cylinder, and described paw unit drives operation by motor.The utility model adopts paw unit, coal operation clearly can be carried out in hydraulic support rear end, dump is avoided to amass, coal can all be transported by conveyer, also coarse coal is there will not be to pile up built phenomenon, the use of passing oil cylinder can meet paw unit and move forward and backward, and can carry out coal operation clearly more easily.
Description
Technical field
The utility model belongs to colliery loading machine technical field, particularly the clear device for coal of one.
Background technology
At present, the thick half-edge coal seam of exploitation 4 ~ 8m, adopt horizontal fragmentation, work plane is arranged along coal seam thickness direction, the coal-mining method that direction of propulsion advances along bearing, in actual production, one of exploitation method has: as shown in Figure 1, the secondary hydraulic support of work plane accommodated side-by-side 2, hydraulic support includes hydraulic pressure after-frame 1 and hydraulic pressure side arm 2, redoiming conveyor 3 be laid on left and right 2 assistant supports between and delayed support 2m, redoiming conveyor 3 connects belt conveyor 4, when pushing up coal by support tail boom 5 let-down, first the coal fallen within conveyer is transported, after the coal falling into conveyer both sides forms the degree of slipping by slope certainly of 35 ~ 40 °, the coal falling into conveyer both sides subsequently can slip on redoiming conveyor and transport under this gradient.
There are the following problems in actual use for this exploitation method: first, forming length 2 meters, width after roof coal caving at bracket outer tail boom rear is dump 6 more than span length, therefore the coal under being caving cannot all transport by redoiming conveyor, and the rate of extraction is difficult to improve; The second, the coal cinder size under caving coal technology is caving is even, and often cause coarse coal to pile up built phenomenon, top coal cannot be transferred smoothly, and now conveyer is close to idle running, and conevying efficiency is low.
Utility model content
Low for the existing rate of extraction, easily to cause coarse coal accumulation built phenomenon problem, the utility model proposes a kind of clear device for coal.
The technical solution of the utility model is: a kind of clear device for coal, the conveyer comprising 2 secondary hydraulic supports and be arranged between hydraulic support, described hydraulic support comprises hydraulic pressure after-frame and hydraulic pressure side arm, the rear end of described hydraulic pressure after-frame is connected with paw unit by passing oil cylinder, and described paw unit drives operation by motor.
Preferably, described paw unit is rack-mount, and described motor is placed on below described support for driving paw unit.
The useful effect that the utility model has is: the utility model adopts paw unit, coal operation clearly can be carried out in hydraulic support rear end, dump is avoided to amass, coal can all be transported by conveyer, also coarse coal is there will not be to pile up built phenomenon, the use of passing oil cylinder can meet paw unit and move forward and backward, and can carry out coal operation clearly more easily.
Accompanying drawing explanation
Fig. 1 is hydraulic support and conveyer configuration schematic diagram in prior art;
Fig. 2 is the accumulation coal schematic diagram that in prior art, work plane cannot transport;
Fig. 3 is the clear device for coal structural representation of the utility model;
In figure: 1, hydraulic pressure after-frame; 2, hydraulic pressure side arm; 3, Bridge type transfer conveyer; 4, belt conveyor; 5, support tail boom; 6, remaining dump; 7, paw unit; 8, motor; 9, support; 10, oil cylinder is passed; 11, hydraulic support.
Specific implementation method
By reference to the accompanying drawings the utility model is described further:
As shown in Figure 3, a kind of clear device for coal, the conveyer comprising 2 secondary hydraulic supports 11 and be arranged between hydraulic support, in the present embodiment preferably, conveyer adopts Bridge type transfer conveyer 3, described hydraulic support comprises hydraulic pressure after-frame 1 and hydraulic pressure side arm 2, and the rear end of described hydraulic pressure after-frame 1 is connected with paw unit 7 by passing oil cylinder 10, and described paw unit 7 drives operation by motor.
Wherein, described paw unit 7 is arranged on support 9, and described motor 8 is placed on described support 9 below for driving paw unit.
The utility model adopts paw unit, coal operation clearly can be carried out in hydraulic support rear end, dump is avoided to amass, coal can all be transported by conveyer, also coarse coal is there will not be to pile up built phenomenon, the use of passing oil cylinder can meet paw unit and move forward and backward, and can carry out coal operation clearly more easily.
Last it is noted that the foregoing is only explanation embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
