Detailed description of the invention
As shown in figures 1 and 3, a kind of mining rectangular slab of stone screening breaker, comprise screening plant and breaker, described screening plant comprises screening frame 1, wherein one end of screening frame 1 is connected with breaker, be provided with dividing plate 4 and transmission device in screening frame 1, dividing plate 4 and the position of screening frame 1 corresponding are equipped with coal breakage district.
Transmission device comprises front sprocket wheel 61 and rear sprocket wheel 62, front sprocket wheel 61 and rear sprocket wheel 62 lay respectively at the two ends of screening frame 1, front sprocket wheel 61 be arranged on the drive unit 3 screening frame 1 outside and be connected, front sprocket wheel 61 and rear sprocket wheel 62 are provided with chain, chain is made up of the chain I 71 be arranged in parallel and chain II 72, is provided with equally spaced coal scraper plate 5 between chain I 71 and chain II 72; As shown in Figure 6, coal scraper plate 5 comprises scraper plate 51, the side of scraper plate 51 is provided with through hole, the axis of through hole and the axis being parallel of scraper plate 51 major axis, axle 52 is provided with in through hole, the two ends of axle 52 fixedly mount connecting ring 53 by bolt 54 attaching nut 55, and connecting ring 53 is fixedly connected with chain II 72 with chain I 71 respectively, and the diameter that the diameter of through hole is greater than axle 52 makes scraper plate 51 rotate along axle under gravity.
As shown in Figure 4 and Figure 5, screening frame 1 is made up of front side board 12, back side panel 13, right baffle-plate 15, base plate 14 and cover plate 11, coal breakage district A10 is provided with in the middle of cover plate 11, base plate 14 is provided with coal breakage district B9, dividing plate 4 offers coal breakage district C81 and coal breakage district D82, be gripper shoe 41 between coal breakage district C81 and coal breakage district D82, dividing plate 4 flushes substantially at the height of the height screened in frame 1 and front sprocket wheel 61 and rear sprocket wheel 62, and coal scraper plate 5 can be moved on dividing plate 4 along chain.
Operation principle of the present invention: as shown in Figure 2, through the coal cinder of primary crushing, be offloaded to screening machine coal unloading hole (namely screening the coal breakage district A on frame cover plate), sprocket rotation before drive unit drives, thus drive chain I, chain II and coal scraper plate to be fed forward by raw coal, when small coal 101 passes through perforate (coal breakage district C and the coal breakage district D) on screening machine dividing plate, by the impact of gravity, via the coal breakage district B that base plate is offered, freely falling body drops to belt conveyor, due to the restriction at the gripper shoe between coal breakage district C and coal breakage district D and scraper plate interval, rectangular coal cinder 102 can not fall, but be transported to hydraulic breaker with coal scraper plate, the sensor of hydraulic breaker detects that rectangular coal passes through, start hydraulic breaker rectangular coal is broken, the ut after fragmentation falls into ribbon conveyer by outlet, when coal scraper plate moves in screening frame, owing to there being the existence (as shown in Figure 4) of dividing plate and gripper shoe, the coal scraper plate (upper strata coal scraper plate) be positioned in dividing plate and gripper shoe is in level, after front sprocket wheel, coal scraper plate at base plate tapping (i.e. coal breakage district B) because the effect of gravity is in vertical state, at base plate, place revert to level again, like this, space between adjacent two coal scraper plates of coal breakage district B is just greater than the space that the upper strata coal scraper plate that corresponds and gripper shoe form, like this, if in the process that coal cinder falls, indivedual rectangular coal cinder due to be along adjacent two upper strata coal scraper plates formed rectangle diagonal fall, the gap so likely formed by upper strata coal scraper plate and gripper shoe and falling, so this rectangular coal cinder also certainly will by the gap between lower floor's coal scraper plate, cause the coal cinder fallen would not be stuck on lower floor's coal scraper plate, thus the shutdown avoiding coal cinder to be brought into interlayer bottom screening machine causing.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
