Description
Technical field
It the utility model is related to a kind of coal mining equipment, and in particular to a kind of sorting of lump coal and breaker composition
Lump coal breaking system.
Background technology
The unearthed colliery in mine is required to crush it, is colliery granule fines by its fragmentation before transport utilizes
After transported and shaped utilization, preferably have impact breaker and hammer to colliery product crushing effect in existing disintegrating machine
Formula disintegrating machine, it is mainly crushed using shock power, applied widely, and crushing members abrasion is small, and replacing is convenient, compared with
Usually applicable knife breaks to crush formula disintegrating machine with double roller and compare to have advantage very much, but it has one for the particle diameter for putting into raw material
Provisioning request, after being unearthed, most of is overall block structure in colliery, when carrying out broken using above-mentioned disintegrating machine, is generally required
Pounded in advance hit processing be fritter raw material, waste the substantial amounts of time；Hammer mill is used as broken equipment in one kind, after it is broken
Material particular diameter it is larger, also need to carry out finished product again sometimes it is in small, broken bits, it is very troublesome, in addition, raw material is after input, to be tiny
The mixture of particle and raw material block, substantial amounts of fine particle need to be fallen by castor bar put into together after, now be easily caused
Solid accumulation at castor bar, not only influences the crushing effect of lump material, while also easily causes the blocking of castor bar, therefore actually broken
Before, often advance with screen cloth and compound is subjected to screening separation, the material block side input of bulk carries out coarse crushing, whole process
Practical operation is very troublesome.
Exist in the prior art and the broken patent of gradation sizing is largely carried out to lump coal, its principal mode is all first to use
Hammer is broken or jaw crusher carries out one-level and crushed, and then carries out two-stage crushing by kibbler roll.One-level is broken and two level is broken
Material is sieved by screening plant between broken, the input kibbler roll that particle is unsatisfactory for requiring is crushed,
Grain meets that what is required is directly sent at finished product.This mode, extremely complex for a set of equipment, especially moving component,
Two sets of disintegrating machines, maintenance cost are very high.Also equipment purchase cost can be significantly increased.
In addition, lump coal, before disintegrating apparatus is entered, pre-screening is highly desirable, and the repetition that can reduce qualified material is broken
It is broken, energy consumption is reduced, it is too small to be also prevented from lump coal particle, the problem of dust emission is big occurs.But existing pre-screening is sieved through sieve,
It is very easy to block sieve aperture, causes follow-up work efficiency to decline or directly shut down.But in existing technology, do not clear up effectively
The device of screen cloth, reciprocating sieve pair has preferable effect with cohesive particle, but the particle for being stuck in sieve aperture can not be removed,
Use for a long time, the work efficiency drop of whole system can be made.But screen cloth is changed to be required for shutting down substantially, it is very troublesome.
The content of the invention
The purpose of this utility model is, there is provided one kind can pre-screening will not putty, and only a set of disintegrating apparatus
Lump coal breaking system.
To achieve these goals, the utility model includes, a pre-sifted separating device and a breaker, the pre-sifted
Separating device includes a casing, and casing top is provided with a back taper hopper, and a combination rotating shaft is fixed in casing, and combination turns
Axle includes an interior axle and an outer shaft, and interior axle is coaxial with outer shaft, and the interior axle passes through the fix bar at both ends and one the
Two grate plates are fixedly connected, and first grate plate is fixed in the outer surface of the outer shaft, and the first grate plate and the second grate plate are provided with flat
Row and uniformly the comb tooth of branch, the spacing being smaller than between the comb tooth of the first grate plate of the comb tooth of second grate plate；
The casing bottom is provided with first feed opening and second feed opening, and the bottom of first grate plate is located at
The top of first feed opening, the bottom of second grate plate are located at the top of the second feed opening；
First feed opening connects with blanking inclined tube, and one end that the blanking inclined tube closes on the first feed opening is provided with one
Base pressure plate, slidably connect to pound with base pressure plate correspondence position and hit bar, pound and hit bar lower end and be fixedly connected with top board, top board and bottom
Be provided with the plate face of pressing plate it is some pound tooth, pound and hit connecting spring between bar and blanking inclined tube top plate, pound and hit on bar fixation and be embedded with
Gear bar, blanking inclined tube upper end, which is fixedly connected with to pound, hits motor, pounds and partial gear is fixedly connected with the rotary shaft for hit motor,
Partial gear engages connection with gear bar,
The blanking inclined tube connects with the blanking tube on breaker top, and the lower section of connectivity part discharging end is provided with a back taper
Shape feed leakage bucket, the lower section of the feed leakage bucket level on blanking tube inwall fix cross the first spreading frame, the first spreading frame
Lower section is provided with a criss-cross second spreading frame, has a folder in the horizontal direction between the second spreading frame and the first spreading frame
Angle, angle are 45 degree, one spreading cone of center bottom Suspending fixation of the second spreading frame；
The bottom of the blanking tube is stretched into breaker, and a broken motor is fixed in bottom in breaker, crushes motor
It is vertically arranged, its top is fixedly connected by power transmission shaft with the bottom center of taper breaker roll, and the breaker roll is covered with one
Wear-resisting housing, the bottom of the blanking tube are stretched into wear-resisting housing, and wear-resisting housing is divided into the first broken portion, second broken from top to bottom
Broken portion and the 3rd broken portion, the first broken portion, the second broken portion and the 3rd broken portion are taper type, and cone angle and breaker roll are equal
