Abstract
The utility model relates to a kind of down-hole coal-gangue separation roller picker, comprise screen frame (unit), be arranged on many roll shafts on described screen frame (unit) and drive the actuating unit of described roll shaft, described roll shaft is provided with multiple screen tray, described screen tray comprises axle sleeve and is arranged on the crushing teeth on described axle sleeve, described axle sleeve is provided with the projection of self-cleaning, described projection stretches in the gap of adjacent screen tray.By axle sleeve being provided with the projection of self-cleaning, projection rotates with axle sleeve, and when the direction of motion is downward, can will fall into sieve aperture, excessive coal cinder is smashed; The coal cinder that can not smash, when the adjacent projection direction of motion upwards time, excessive coal cinder can be brought back on screen tray, ensure material can not block sieve axle; Each projection rotates a circle, and carries out self-cleaning once.
Description
Technical field
The utility model relates to engineering technical field of mechanical equipment, particularly a kind of down-hole coal-gangue separation roller picker.
Background technology
In traditional coal mining system, the spoil that underground mining goes out and coal are transported to the washing of ground washery by raw coal transportation system, and the Piling of Gangue Cheng Shan after sorting, land occupation, causes environmental pollution.In order to " turn mode, adjust structure ", with Resources for construction economizing type, environmentally friendly mining area for target, the production that particularly old mine production link is many, raw coal percentage of shale content is high is actual, is realizing down-hole " coal-gangue separation " particular importance.Roller picker is mainly used in mineral grain graded operation.During work, drive system drives sieve axle to rotate indirectly, and all sieve axles lead to rotation, and then screen tray leads to rotation, and by coal cinder forwards transportation, the coal cinder that granularity is little simultaneously falls from the gap of screen tray, completes screening.But some coal cinder width is less than gap, but length is large, also can fall from the gap of screen tray, occurs that coal cinder blocks the phenomenon of sieve axle.If China Patent No. is the utility model patent of CN201020140626.X, publication date is on November 17th, 2010, discloses a kind of toothed roller type roller screen.The technical scheme adopted is: comprise bearing block, sieve axle, screen tray, base and drive system, be characterised in that: screen tray structure is: the tooth being shaped with 1 ~ 3 row in the outside of wheel hub symmetrical is convex.Bearing block is conjuncted bearing block, and its structure is divided into upper and lower two bodies, and lower body is integrally-built bearing base, and upper body is several independently bearing upper covers.Screen tray diameter on adjacent sieve axle is identical or different.In such scheme, although have tooth convex in the arranged outside of wheel hub, improve raw coal flour effect, be beneficial to the screening of coal.But such scheme still exists coal cinder blocks the defect cannot clearing up sieve axle.
Utility model content
In view of this, the purpose of this utility model is that there is coal cinder for prior art blocks the defect cannot clearing up sieve axle, provides a kind of down-hole coal-gangue separation roller picker.
The utility model discloses a kind of down-hole coal-gangue separation roller picker, comprise screen frame (unit), be arranged on many roll shafts on described screen frame (unit) and drive the actuating unit of described roll shaft, described roll shaft is provided with multiple screen tray, described screen tray comprises axle sleeve and is arranged on the crushing teeth on described axle sleeve, described axle sleeve is provided with self-cleaning projection, described projection stretches in the gap of adjacent screen tray.
A kind of down-hole coal-gangue separation roller picker that the utility model provides, has following beneficial effect: by axle sleeve being provided with the projection of self-cleaning, projection rotates with axle sleeve, and when the direction of motion is downward, can will fall into sieve aperture, excessive coal cinder is smashed; The coal cinder that can not smash, when the adjacent projection direction of motion upwards time, excessive coal cinder can be brought back on screen tray, ensure material can not block sieve axle; Each projection rotates a circle, and carries out self-cleaning once.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model embodiment roller picker;
Fig. 2 is the schematic diagram of the utility model embodiment roller picker;
Fig. 3 is the generalized section of the utility model embodiment roller picker.
