Specific embodiment
As shown in figures 1 and 3, a kind of mining rectangular slab of stone screening breaker, including screening plant and breaker, the sieve
Screening device includes screening rack 1, and wherein one end of screening rack 1 is connected with breaker, and 4 He of partition plate is equipped in screening rack 1
Transmission device, partition plate 4 and 1 corresponding position of screening rack are equipped with coal breakage area.
Transmission device includes preceding sprocket wheel 61 and rear sprocket wheel 62, and preceding sprocket wheel 61 and rear sprocket wheel 62 are located at screening rack 1 respectively
Both ends, preceding sprocket wheel 61 are connected with the driving device 3 being arranged on outside screening rack 1, and preceding sprocket wheel 61 and rear sprocket wheel 62 are equipped with chain
Item, chain are made of the chain I 71 and chain II 72 being arranged in parallel, and are equipped between chain I 71 and chain II 72 and are scraped at equal intervals
Coal plate 5；As shown in fig. 6, coal scraper plate 5 includes scraper plate 51, the one side of scraper plate 51 is equipped with through hole, axis and 51 long axis of scraper plate of through hole
Axis it is parallel, axis 52 is equipped in through hole, the both ends of axis 52 pass through 54 attaching nut 55 of bolt and connection ring 53, connection is fixedly mounted
Ring 53 is fixedly connected respectively with chain I 71 and chain II 72, and the diameter of through hole enables scraper plate 51 in weight more than the diameter of axis 52
It is rotated under the action of power along axis.
As shown in Figure 4 and Figure 5, rack 1 is screened by 11 groups of front side board 12, back side panel 13, right baffle-plate 15, bottom plate 14 and cover board
Into equipped with coal breakage area A10 among cover board 11, bottom plate 14 is equipped with coal breakage area B9, and coal breakage area C81 and coal breakage are offered on partition plate 4
For support plate 41 between area D82, coal breakage area C81 and coal breakage area D82, height of the partition plate 4 in screening rack 1 and preceding sprocket wheel 61 with
And the height of rear sprocket wheel 62 is substantially flush so that coal scraper plate 5 can be moved along chain on partition plate 4.
The operation principle of the present invention：As shown in Fig. 2, the coal cinder by primary crushing, is offloaded to screening machine coal unloading hole（Sieve
Select the coal breakage area A in rack cover）, sprocket wheel rotates before driving device drives, so as to drive chain I, chain II and coal scraper plate will
Raw coal is fed forward；Small coal 101 passes through the perforate on screening machine partition plate（Coal breakage area C and coal breakage area D）When, by the shadow of gravity
It rings, via the coal breakage area B opened up on bottom plate, belt conveyor is fallen under freely falling body；Due between coal breakage area C and coal breakage area D
Support plate and scraper plate interval limitation, strip coal cinder 102 is not fallen out, but is transported to hydraulic breaker, liquid with coal scraper plate
Pressure crusher sensor detect strip coal by, start hydraulic breaker strip coal is crushed, broken nuts by
Outlet falls into ribbon conveyer；Coal scraper plate in screening rack when moving, due to there is the presence of partition plate and support plate（Such as Fig. 4 institutes
Show）, the coal scraper plate on partition plate and support plate（Upper strata coal scraper plate）In horizontality, after preceding sprocket wheel, coal scraper plate exists
Bottom plate tapping（That is coal breakage area B）Since the effect of gravity is in vertical state, horizontality is revert to again at bottom plate, this
Sample, the gap between the two neighboring coal scraper plate of coal breakage area B are greater than corresponding upper strata coal scraper plate and support plate
The gap of composition, if in this way, during coal cinder falls, indivedual strip coal cinders are due to being along two neighboring upper strata coal scraper plate
The diagonal of formed rectangle falls, thus possibly through upper strata coal scraper plate and gripper shoe groups into gap and under
Fall, then the strip coal cinder also certainly will can cause the coal cinder fallen that would not be stuck in by the gap between lower floor's coal scraper plate
On lower floor's coal scraper plate, so as to avoid shutdown caused by coal cinder is brought into screening motor spindle interlayer.
Basic principle of the invention and main feature and advantages of the present invention has been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
