Description
Technical field
The present invention relates to Scraper Conveyor in Mining Face and transportation roadway elevating conveyor, a kind of novel bog-head coal
Ply side dump structure.
Background technology
At present, the ratio shared by thin and ultra-thin coal seam in the oldest domestic mining area gets more and more.For keeping away
Exempt from the wasting of resources, it is achieved resources balance is exploited.Each mining area increases thin and ultra-thin coal seam exploitation power
Degree.For meeting the exploitation needs in each mining area, in recent years coal machine profession for girdle particularly 1m with
The exploitation manufacture of lower ultra-thin coal seam fully-mechanized mining equipment, develops the swiftest and the most violent.
The existing thin coal seam scraper blade conveyor all ends of head unloading manner unload form, because scraper plate carries
Machine head uses end to unload mode, causes conveyer head driving section to exist on existing matching equipment and is permitted
Many problems the most fully solve, and are mainly manifested in the following aspects: 1, power part uses old man side
It is arranged vertically, then causes face end support in crossheading delayed excessive to old man side, cause and ventilate at this freely,
Between termination frame and middle frame frame, supporting difficulty, easily causes danger.2, power part uses rib side vertical
Arranging, because thin seam working surface base plate exists bigger drop with transportation roadway base plate, coal-winning machine cuts at head
During coal, the coal that is scattered fragile head power part, and the coal cut off do not enters elevating conveyor, needs artificial
Clear coal, labor strength is big.3, power part uses and is arranged in parallel, owing to decelerator profile affects,
Cause head, tail discharge height excessive.Conveyer head occupies the space above work surface, when
When face height changes, head, tail at conveyer need to cut at the end by force, and workload is big.
Summary of the invention
It is an object of the invention to provide a kind of Novel thin coal seam overlap side dump structure, it is possible to realize scraper plate
Conveyer head and the synchronizing moving of elevating conveyor, and improve handpiece of scraper conveyer, elevating conveyor machine
Tail and hydraulic support arrangement space, reduce head roadway support difficulty thus improve the safety of work surface
Property and coal mining efficiency.
A kind of Novel thin coal seam overlap side dump structure, including conveyer and elevating conveyor, its special feature
It is: being provided with unloading link slot at described transfer conveyor tail, the head of described conveyer is fixed
On the unloading link slot of this transfer conveyor tail.
The coal-ploughing board of arc is wherein installed by the conveyer head above unloading link slot, it is thus possible to
The transfer conveyor tail turning to and then falling into lower section near the coal of conveyer head is made then to be continued by elevating conveyor
Continuous conveying.
Wherein conveyer head includes headstock, is provided with sprocket shaft group, also includes on this headstock
The power part being in transmission connection with this sprocket shaft group, this power part is arranged in the elevating conveyor on rib direction
Outside portion's groove baffle plate, and this power part is parallel with this elevating conveyor middle trough baffle.
Wherein sprocket shaft group is arranged on outside elevating conveyor middle trough baffle.
The most also include hydraulic pressure height-regulating device, this hydraulic pressure height-regulating device simultaneously with the head of conveyer head
The unloading link slot of frame and transfer conveyor tail connects, it is thus possible to regulation headstock is relative to unloading link slot
Height.
Technical scheme, solves the power part installation site that the existing end mode of unloading causes and does not conforms to
Reason problem, it is to avoid the delayed problems of too of hydraulic support that end hydraulic support is arranged with work surface, it is to avoid
The smooth problem of hydraulic support ventilation that end hydraulic support and work surface are arranged.The technical side of the present invention
Case, by changing the unloading manner of head, changing handpiece structure, the installation site of change power part,
Improve conveyer head, transfer conveyor tail and hydraulic support arrangement space, reduce head roadway support
Difficulty, improves safety and the coal mining efficiency of work surface.

Detailed description of the invention
As shown in Figure 1,2,3, 4, the present invention is a kind of Novel thin coal seam overlap side dump structure,
Including conveyer 8 and elevating conveyor 9, at described elevating conveyor 9 tail, unloading link slot 5, institute are installed
The head stating conveyer 8 is fixed on the unloading link slot 5 of this elevating conveyor 9 tail.In unloading
The coal-ploughing board 7 of arc is installed, it is thus possible to make near defeated by conveyer 8 head above link slot 5
The coal sending machine 8 head turns to and then falls into elevating conveyor 9 tail of lower section and then continued defeated by elevating conveyor 9
Send.
Wherein conveyer 8 head includes headstock 1, is provided with sprocket shaft group 2 on this headstock 1,
Also including the power part 3 being in transmission connection with this sprocket shaft group 2, this power part 3 is arranged on rib direction
On elevating conveyor 9 middle trough baffle outside, and this power part 3 and this elevating conveyor 9 middle trough baffle
Parallel.Sprocket shaft group 2 is arranged on outside elevating conveyor 9 middle trough baffle.Additionally include hydraulic pressure to heighten
Device 4, this hydraulic pressure height-regulating device 4 simultaneously with headstock 1 and elevating conveyor 9 machine of conveyer 8 head
The unloading link slot 5 of tail connects, it is thus possible to regulation headstock 1 is relative to the height of unloading link slot 5.
The using method of the present invention is:
During use, coal stream moves to headstock 1 direction from the tail of conveyer 8, when coal flows to reach reprinting
When machine 9 unloads headstock 1 side of link slot 5 upper conveyor 8 head, in the guiding of coal-ploughing board 7
Under effect, coal circulation to an angle of 90 degrees, directly drops to be located at elevating conveyor 9 below headstock 1
Tail, thus continued conveying by elevating conveyor 9.
The present invention unloads coal principle by changing conveyer head, devises the head of overlapping side dumping form
Frame, is arranged on whole power part 3 outside elevating conveyor 9 middle trough baffle in rib direction, and this is heavy
Folded side dumping structure can share the motor of same model, decelerator, sprocket wheel compared with unloading structure with former end
Axle group 2 parts such as grade, thus decrease the kind of same model product.
As shown in Figure 1, 2, the present invention realizes thin coal bed fully-mechanized mining working face conveyor overlap side dumping first
Arrange, headstock 1 is designed to overlapping side dumping structure, runs to unloading of elevating conveyor 9 at coal stream material
When carrying above link slot 5, changed the traffic direction of material by the coal-ploughing board 7 on conveyer 8, from
And further material is unloaded on the unloading link slot 5 of elevating conveyor 9.By this change, permissible
By the Position Design of sprocket shaft group 2 at the rear of unloading port, so that the installation of conveyer power part 3
Position also there occurs change.
As it is shown on figure 3, the envisaged underneath at headstock 1 has hydraulic pressure height-regulating device 4, by this device
The unloading link slot 5 of headstock 1 with elevating conveyor 9 is linked into an integrated entity, it is achieved conveyer 8 and reprinting
The synchronizing moving of machine 9, realizes the adjustment of headstock 1 discharge height simultaneously.
As shown in Figure 4, the present invention unloads coal principle by changing conveyer 8 head, by power part 3
The change of installation site, conveyer 8 drive division is arranged in the middle part of the elevating conveyor 9 in rib direction
Groove baffle plate side, no longer takies the space of face end support.Further improve conveyer 8 head, elevating conveyor 9
The arrangement space of tail and hydraulic support, makes the face end support can be parallel with work surface intermediate support 10
Arrange, improve the ventilation situation of conveyer 8 head and elevating conveyor 9 tail, reduce head roadway support
Difficulty, improves safety and the coal mining efficiency of work surface.
