Abstract
The utility model relates to a conveyer of digging the working face and using is combined in the mine, specifically is a combine and to dig tail portion and push away coal device, but including hinging in second cargo airplane revolving platform front end and tilting's lapse shovel board, hinge in combining the machine of digging back supporting part subassembly and passing the lift cylinder between the shovel board rear end upper portion, hinge in second cargo airplane revolving platform rear end one side and combine the angling cylinder between the machine of digging, all hydro -cylinders pass through hydraulic pressure lock and oil pipe connects on bigeminy hydraulic control valve, and bigeminy hydraulic control valve concatenates and digs quick -witted hydraulic system in combining, install the control valve control rod on the bigeminy hydraulic control valve. The advantage that combine and to dig tail portion and push away coal device has as follows: combine and to dig tail portion and push away coal device after the transformation produces coal the back at first cargo airplane and uses the machine of digging of combining to advance the coal (cash) that comes out first cargo airplane with recessional mode directly to shift the coal onto and slide and transport, and it can speedy drivage and the demand when engaging in this profession to have satisfied in the pit any tunnel opening and turn.
Description
Technical field
This utility model relates to the conveying arrangement that mine fully mechanized workface uses, and specifically a kind of fully-mechanized digging machine afterbody pushes away device for coal.
Background technology
At present, coal mine underground tunneling roadway transportation system is mainly by fully-mechanized digging machine first conveyor, coal under fully-mechanized digging machine cut, spoil and other items are transported to fully-mechanized digging machine second conveyor, then at equipment such as the drag conveyor overlapped by second conveyor, rubber conveyers, coal, spoil and other items are transported.But when short distance digging laneway, laneway opening section and fully-mechanized digging machine turn round, because being limited by drift section, and the equipment of installation is more, causes work surface narrow space, pedestrian's difficulty, bring the biggest hidden danger to safety in production.On the other hand, if fully-mechanized digging machine carries second conveyor, when fully-mechanized digging machine driving turning roadway, because by second conveyor length limitation, causing radius of turn big, shipment is extremely difficult, and the tunnel turning driving used time is longer.If not carrying second conveyor, the coal of first conveyor conveying, spoil and other items will directly fall within ground, only by artificial shipment, add labor strength.
Summary of the invention
This utility model is in order to solve the problem that second conveyor is not suitable for using when short distance digging laneway, laneway opening section and fully-mechanized digging machine turn round, it is provided that a kind of fully-mechanized digging machine afterbody pushes away device for coal.
This utility model is achieved through the following technical solutions: a kind of fully-mechanized digging machine afterbody pushes away device for coal, including being articulated with second conveyor rotary table front end and the passage shovel board that can rotate upwardly and downwardly, it is articulated with the hoist cylinder between fully-mechanized digging machine rear support parts and passage shovel board upper rear end, is articulated with the angling cylinder between side, second conveyor rotary table rear end and fully-mechanized digging machine；
All oil cylinders are connected on bigeminy hydraulic control valve by hydraulic lock and oil pipe, and bigeminy hydraulic control valve is serially connected with in fully-mechanized digging machine hydraulic system, and described bigeminy hydraulic control valve is provided with control valve stick.
Time specifically used, control valve stick controls the realization passage of bigeminy hydraulic control valve, and shovel board is upper and lower, left and right is movable, and coordinate fully-mechanized digging machine to advance, retreat and realize coal, spoil of being transferred out by first conveyor and other items passage to trench drag conveyor, goods is transported.
Fully-mechanized digging machine afterbody described in the utility model pushes away device for coal and has the advantage that as follows:
1) easy to operate: during operation, to have only to that driver of roadheader operation control valve stick is upper and lower to be controlled to push away the oil cylinder in device for coal system and stretch length.
2) meet and require: improved fully-mechanized digging machine afterbody pushes away mode that device for coal uses fully-mechanized digging machine to move forward and backward after first conveyor produces coal and first conveyor coal (cash) out is directly shifted onto coal slips and transport, solve originally at laneway opening and when turning the long impact of fully-mechanized digging machine itself produce coal transport, meeting in down-hole any laneway opening and turning can speedy drivage and demand when engaging in this profession.
3) potential safety hazard and labor intensity: eliminate the second conveyor head of former use and personnel carry out the potential safety hazard that left and right promotes time tail is directly connected to produce coal, the personnel that also greatly reduce carry out using when producing coal manually coalingging, and reduce the labor intensity of employee.
4) effect: when driving effect is by original laneway opening and turning, 0.2 meter of work rises to present 0.4 meter work, improves 200%.
5) cost: fully-mechanized digging machine afterbody pushes away the transformation of device for coal system and all uses waste and old Hydraulic Elements, and the leftover pieces etc. scrapping steel process, and significantly reduce cost, has saved substantial amounts of fund.
Accompanying drawing explanation
Fig. 1 is the structural representation that fully-mechanized digging machine afterbody described in the utility model pushes away device for coal, and wherein top is divided into front view, bottom to be divided into top view (in figure, hoist cylinder is not drawn into).
In figure: 1-second conveyor rotary table, 2-elapses shovel board, 3-rear support parts, 4-hoist cylinder, 5-angling cylinder, 6-hydraulic lock, 7-bigeminy hydraulic control valve, 8-control valve stick.
Detailed description of the invention
A kind of fully-mechanized digging machine afterbody pushes away device for coal, including being articulated with second conveyor rotary table 1 front end and the passage shovel board 2 that can rotate upwardly and downwardly, it is articulated with the hoist cylinder 4 between fully-mechanized digging machine rear support parts 3 and passage shovel board 2 upper rear end, the angling cylinder 5 being articulated with between side, second conveyor rotary table 1 rear end and fully-mechanized digging machine；
All oil cylinders are connected on bigeminy hydraulic control valve 7 by hydraulic lock 6 and oil pipe, and bigeminy hydraulic control valve 7 is serially connected with in fully-mechanized digging machine hydraulic system, and described bigeminy hydraulic control valve 7 is provided with control valve stick 8.
