Description
Technical field
The utility model relates to a kind of colliery and uses coal separation equipment, particularly is applicable to the down-hole mechanical movable-sieve jig of sorting 20～350mm particle size fraction coal.
Background technology
Present down-hole mechanical movable-sieve jig; Like patent announcement number is the down-hole mechanical movable-sieve jig of CN101486012A; Announced and a kind ofly comprised casing, assemble and utilize the moving sieve nest that main driving machine structure and toggle drive and the down-hole mechanical movable-sieve jig of material elevator structure on it; The main driving machine structure is arranged in the casing lateral surface, and the material elevator structure adopts two scratch board conveyors that are arranged in juxtaposition that promote transportation lump coal and spoil respectively, and this down-hole mechanical movable-sieve jig takes up room bigger; Acquire a certain degree of difficulty in the underworkings layout; It is applicable to down-hole large section roadway condition of work, arranges with regard to the cross dimensions that needs the kaneh for most underworkings, has been suitable for for light section tunnel, down-hole is just more difficult.
Summary of the invention
The purpose of the utility model provides a kind of improved down-hole mechanical movable-sieve jig; Solved that the bulk that existing down-hole mechanical movable-sieve cradle exists is big, structure compactness issue not; Made full use of condition of work under the existing well, guaranteed the reliability and the security of downhole production, its compact conformation is reasonable; It is little to take up space, easily the mounting arrangements in the down-hole.
The purpose of the utility model is achieved in that and comprises casing, driving mechanism, toggle, moving sieve nest, discharge refuse wheel mechanism and scratch board conveyor; It is characterized in that: the driving mechanism that is installed on the casing is connected with toggle through connecting rod; The suspension rod on the toggle and the upper articulation of moving sieve nest; The front portion of moving sieve nest and casing anterior hinged, the centre is equipped with discharge refuse and takes turns in the casing, and the flange of lower box slate chute is connected the spoil flange and the lump coal of integral type scratch board conveyor respectively and sieves the thing flange thoroughly with lump coal and the flange that sieves the thing chute thoroughly; In the scratch board conveyor cell body, moveable bulkhead is housed; Moveable bulkhead is divided into the scratch board conveyor cell body spoil groove and lump coal and sieves the thing groove thoroughly, and the scratch board conveyor head is installed in the casing front portion, is higher than water surface place.
The beneficial effect of the utility model is: solved existing down-hole mechanical movable-sieve jig and taken problems such as lane space is big, assembling trouble, installation and maintenance requirement skill level height, maintenance difficult; And be applicable to the underworkings condition of work; Satisfy the security and the reliability of down-hole, reduce the colliery operation cost, reduce carbon emission; Reduce noise, reduce environmental pollution.
This down-hole mechanical movable-sieve jig is employed in arranges driving mechanism on the casing, simplify the structure, and has reduced setting height(from bottom), has reduced floor space, makes layout more reasonable, has improved the ability to provide the auxiliary items of main transportation system under equipment and the coal mine.Use the integral type scratch board conveyor; In the middle of the conveying trough of scratch board conveyor, install the dividing plate of separating spoil and lump coal and sieving thing thoroughly additional; Guarantee separated spoil and lump coal and sieved the accuracy of thing packing thoroughly, also reduced the interference with miscellaneous equipment, improved sorting and conevying efficiency.
Description of drawings:
Fig. 1 is the structure chart of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The practical implementation method:
Below in conjunction with accompanying drawing present embodiment is further specified
Can know by Fig. 1-2; The driving mechanism 4 that is installed on the casing 1 is connected with toggle 2 through connecting rod 3; The upper articulation of suspension rod on the toggle 2 and moving sieve nest 5, the front portion of moving sieve nest 5 and casing 1 anterior hinged, the discharge refuse that the discharge spoil is installed in the middle of in the casing 1 takes turns 6; Discharge refuse wheel cross section is a regular hexagon; The flange of casing 1 bottom slate chute 8 and lump coal and the flange that sieves thing chute 9 thoroughly respectively with the spoil flange of integral type scratch board conveyor 10 and lump coal with sieve the thing flange thoroughly and be connected, in scratch board conveyor 10 cell bodies, moveable bulkhead 14 is housed, moveable bulkhead 14 is divided into scratch board conveyor 10 cell bodies spoil groove 12 and lump coal and sieves thing groove 13 thoroughly; Lump coal and the lump coal that sieves thing groove 13 and lower box thoroughly with sieve thing chute 7 thoroughly and be connected, scratch board conveyor head 15 is installed in casing 1 front portion and is higher than water surface place.
Down-hole mechanical movable-sieve jig job step: in underworkings, arrange down-hole mechanical movable-sieve jig, in casing, add water to overfall.Raw coal gets into casing through coal-in port and falls on the moving sieve nest of arranging the inclination angle; Driving mechanism drives moving sieve nest through toggle and does upper and lower reciprocating motion around the pin joint that connects with casing; The promotion raw coal moves ahead; Make raw coal in moving ahead by density stratification, cross downflow weir at the light density lump coal on upper strata and fall into the lump coal of integral type scratch board conveyor and sieve in the thing groove thoroughly through the lump coal chute; Crossing the discharge refuse wheel at the heavy density spoil of lower floor falls in the spoil groove of integral type scratch board conveyor through slate chute; Short grainedly sieve the compass screen surface hole that thing passes on the moving sieve nest and fall into the lump coal of integral type scratch board conveyor and sieve in the thing groove thoroughly through sieving the thing chute thoroughly.The integral type scratch board conveyor is respectively with spoil and lump coal and sieve thing thoroughly and promote and to transport out the water surface, through scratch board conveyor head spoil discharge gate and lump coal and sieve the thing discharge gate thoroughly and discharge respectively.
