Abstract
A kind of scraper plate machine-cut bottom be the utility model is related to flexible poppet, it is characterised in that：Outer jar support（2）It is enclosed on inner casing base（1）On, outer jar support（2）There is hydraulic cylinder both sides respectively（6）, hydraulic cylinder（6）Pass through at least two pressing plates（7）With outer jar support（2）It is fixed, adjust top plate（3）With alignment pin B（5）It is fixed on outer jar support（2）Top simultaneously can adjustment angle.In the case where coal-face height changes, the even running on working face of whole scrapper conveyor is allow by the regulation for the poppet that stretches, reduces the flexural deformation of scrapper conveyor to greatest extent, effectively reduces coal mining difficulty, improve the service life of scrapper conveyor.
Description
Technical field
The utility model belongs to coal mine machinery equipment technology field, and in particular to a kind of flexible poppet in scraper plate machine-cut bottom.
Background technology
Poppet is the critical piece of scrapper conveyor, is connected with driving section, main to play support, balance scrapper conveyor driving section
Effect.There is two kinds of " cutting top " or " cutting bottom " according to the different coal winning technologies of working face coal seam distributed architecture.When working face coal seam needs
" cutting bottom " can cause floor undulation to be uneven when exploiting；Scrapper conveyor interlude is flexible connection structure, under normal circumstances all
It is adapted to being uneven for coal-face bottom plate；And head, tail driving section and interlude are Hard link, so head,
How tail driving section adapts to the coal-face for changing drop at this moment, turns into domestic scrapper conveyor manufacturer and compels to be essential
The problem to be captured.
The content of the invention
The defects of being to overcome prior art of the present utility model, there is provided a kind of flexible poppet in scraper plate machine-cut bottom, from
And efficiently solve problems of the prior art.
To achieve the above object, the utility model adopts the technical scheme that：A kind of flexible poppet in scraper plate machine-cut bottom, its
It is characterised by：Outer jar support（2）It is enclosed on inner casing base（1）On, outer jar support（2）There is hydraulic cylinder both sides respectively（6）, hydraulic cylinder
（6）Pass through at least two pressing plates（7）With outer jar support（2）It is fixed, adjust top plate（3）With alignment pin B（5）It is fixed on outer jar support
（2）Top simultaneously can adjustment angle.
The hydraulic cylinder（6）Both sides are provided with multiple cushion blocks（8）Pile is got up, left and right sides hydraulic cylinder（6）By outer jar support（2）
Cushion block is used after jack-up（8）Support, cushion block（8）Use bolt（9）It is fixed.
The regulation top plate（3）It is provided with alignment pin A（4）, adjust top plate（3）Both sides are provided with aperture（10）, to
Fixed head, tail driving section.
Operation principle：Scrapper conveyor head, tail driving section are arranged on regulation top plate, when coal-face height changes
Height by adjusting hydraulic cylinder jacks up outer jar support, and height is supported after adjusting properly with cushion block, and is fixed with fixing bolt；When
Adjusted during coal-face angle change top plate can flexible modulation angle, make head or tail driving section with whole working face all the time
Keeping parallelism.
The beneficial effects of the utility model are：In the case where coal-face height changes, pass through the tune for the poppet that stretches
Section allows the even running on working face of whole scrapper conveyor, reduces the flexural deformation of scrapper conveyor to greatest extent, effectively
Coal mining difficulty is reduced, improves the service life of scrapper conveyor.
Brief description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model left view；
In figure：1- inner casing bases, the outer jar supports of 2-, 3- regulation top plates, 4- alignment pins A, 5- alignment pin B, 6- hydraulic cylinder, 7-
Pressing plate, 8- cushion blocks, 9- bolts, 10- apertures.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Embodiment 1, see Fig. 1-2, a kind of flexible poppet in scraper plate machine-cut bottom, it is characterised in that：Outer jar support 2 is enclosed on inner casing
On base 1, there is hydraulic cylinder 6 the outer both sides of jar support 2 respectively, and hydraulic cylinder 6 is fixed by least two pressing plates 7 and outer jar support 2, adjust
Section top plate 3 is fixed on the outer top of jar support 2 with alignment pin B5 and can adjustment angle.
The both sides of hydraulic cylinder 6 are provided with multiple cushion blocks 8 pile and got up, and left and right sides hydraulic cylinder 6 is used after outer jar support 2 is jacked up
Cushion block 8 is supported, and cushion block 8 is fixed with bolt 9.
The regulation top plate 3 is provided with alignment pin A 4, and regulation top plate 3 both sides are provided with aperture 10, to fixed machine
Head, tail driving section.
The utility model is assembled in head, tail driving section bottom surface, by hydraulic cylinder, then is aided with cushion block support, makes machine
Head or tail driving section remain parallel with whole working face, adapt to the height change of coal-face bottom plate.
