Abstract
The utility model discloses a kind of ultrashort slat conveyer, comprise scraper chain, chute and head section, the machine head chain wheel of described head section connects emulsion motor, and described emulsion motor is connected with emulsion power pack, is provided with a governor valve between described emulsion motor and emulsion power pack.Head section emulsion motor of the present utility model substitutes former retarder, fluid coupling, coupler and electrical motor, and such complete machine structure greatly simplifies, and is conducive to very-short-reach transport.Driving surface has emulsion power pack, propulsion source is provided to emulsion motor, emulsion motor is selected to be fixed displacement motor, and on emulsion power pack to emulsion motor duplexure, be connected in series a governor valve to realize " equivalent variable pump ", build " equivalent variable pump " and emulsifying fixed quantity hydraulic motor volume speed-modulating loop to realize permanent torque and export, meet the requirement of ultrashort slat conveyer starting with full load.
Description
Technical field
The utility model belongs to Coal Transportation field of mechanical technique, particularly a kind ofly coal seam thickness about 10 meters, adopts the ultrashort slat conveyer of coal-mining method that horizontal fragmentation, driving surface are arranged along coal seam thickness direction, direction of propulsion advances along bearing for half-edge coal seam.
Background technology
Slat conveyer is a kind of continuative transport machinery having flexible traction mechanism, is the machinery for coal-face fortune coal.Its driving component is scraper chain, holding cutting device is chute, and the sprocket wheel of scraper chain pile warp head, tail is connected into enclosed shape and is placed in chute, and chute is laid completely along transportation route, the coal loaded in work in chute is drawn by scraper chain, slides into unloading end and unload in chute.Slat conveyer is the unique Coal Transport equipment of inclined longwall formula coal-face.
Current slat conveyer type of drive is that electrical motor makes scraper chain operation carry coal through fluid coupling retarder band movable sprocket, and according to inclined longwall formula coal mining feature, Scraper Conveyor in Mining Face can lay more than 100 meter even more than 200 meter long.
For half-edge coal seam and coal seam thickness about 10 meters, usually adopt horizontal fragmentation, driving surface is arranged along coal seam thickness direction, the coal-mining method that direction of propulsion advances along bearing.This coal-mining method face length only has about 10 meters, if adopt the slat conveyer of current manufacturer production, only lays about 10 meters, just shows head especially too heavy.
Utility model content
In order to solve the too heavy problem of existing head, the utility model provides a kind of ultrashort slat conveyer.
The technical solution of the utility model is: a kind of ultrashort slat conveyer, comprise scraper chain, chute and head section, the machine head chain wheel of described head section connects emulsion motor, described emulsion motor is connected with emulsion power pack, is provided with a governor valve between described emulsion motor and emulsion power pack.
Preferably, described scraper chain is round-link chain.
The beneficial effects of the utility model: head section emulsion motor of the present utility model substitutes former retarder, fluid coupling, coupler and electrical motor, and such complete machine structure greatly simplifies, are conducive to very-short-reach transport.Driving surface has emulsion power pack, propulsion source is provided to emulsion motor, emulsion motor is selected to be fixed displacement motor, and on emulsion power pack to emulsion motor duplexure, be connected in series a governor valve to realize " equivalent variable pump ", build " equivalent variable pump " and emulsifying fixed quantity hydraulic motor volume speed-modulating loop to realize permanent torque and export, meet the requirement of ultrashort slat conveyer starting with full load.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ultrashort slat conveyer of the utility model;
Fig. 2 is the connection diagram of the ultrashort slat conveyer of the utility model and hydraulic support;
In figure: 1, emulsion motor; 2, machine head chain wheel; 3, round-link chain; 4, chute; 5, scraper plate.
Detailed description of the invention
By reference to the accompanying drawings the embodiment that the utility model provides is described in further detail:
As shown in Figure 1, a kind of ultrashort slat conveyer, comprise scraper chain, chute 4 and head section, the machine head chain wheel 2 of described head section connects emulsion motor 1, described emulsion motor 1 is connected with emulsion power pack, is provided with a governor valve between described emulsion motor 1 and emulsion power pack.
Wherein, emulsion motor 1 drives machine head chain wheel 2 to rotate thus drives scraper chain to draw coal in chute 4, and round-link chain 3 selected by the present embodiment middle scraper chain.
On scraper chain, fix a scraper plate 5 every a segment distance, and scraper chain and scraper component are placed in chute 4.Chute 4 top scraper chain drives scraper plate 5 that coal body is slided in chute 4 by chain wheel drive and realizes defeated coal; Chute 4 bottom scraper chain and scraper component are returned by chain wheel drive zero load, and formation scraper chain and scraper component are along the upper and lower electrodeless operation of whole scraper plate 5 length.
Ultrashort slat conveyer of the present utility model is connected with adopting jack between hydraulic support, for mining in production process, first pushes away ultrashort slat conveyer near rib, rear moving hydraulic support near ultrashort slat conveyer, to complete a circulation of coal winning technology.Slat conveyer is a kind of continuative transport machinery having flexible traction mechanism, is the machinery for coal-face fortune coal.Slat conveyer is the unique Coal Transport equipment of inclined longwall formula coal-face.
In this description, the utility model is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
