Description
Technical field
The utility model belongs to the material of belt feeder overlap joint link and reprints the technical field of carrying, and is specifically related to a kind of belt feeder transfer point V-type buffer slide chute.
Background technology
The main transportation mode of mine coal is sealing-tape machine transportation.Due to factors such as turn round in stage progress, the tunnel of roadway opening, the specified transportation range of sealing-tape machine, the path of transportation is always connected together by multi-section sealing-tape machine ladder, the unloading portion that form is generally previous stage occupies a commanding position and is overlapped on afterbody or the middle part of rear one-level sealing-tape machine, coal stream relies on inertia and Action of Gravity Field disengaging our department sealing-tape machine to dump to rear class sealing-tape machine and completes reprinting, and this has just brought up the transfer point of a plurality of various discrepancy in elevation and angle.
Belt feeder transfer point chute is mainly adopted in two ways both at home and abroad at present, and a kind of is dustpan shaped, and another kind is spiral chute type.The latter's spiral chute needs professional equipment to carry out punching press, difficulty of processing is large, and cost Gao Mao, the on-the-spot comparatively complexity of installing, and granular material and coal slime easily cause blocking, be more suitable for the transshipment of high drop (as coal bunker) or clean fine coal, low, the processed complex of cost performance when the belt feeder that is applied in small drop is reprinted, installation are inconvenient.
Current conventional practice is that its deflector chute adopts about 20mm plate iron to be welded at " dustpan " shape deflector chute of drop space mounting.This kind of device can simply complete the task of letting out coal stream under constraint substantially, but in operational process, also exposes many defects.
This kind of transfer point " dustpan " shape deflector chute, upper edge is overlapped in unloading roller horizontal center line position, and base plate is smooth, is about 45 degree with horizontal sextant angle, and both sides side board is perpendicular to base plate; And because needs flow to row constraint by coal gradually, to adapt to smoothly subordinate's sealing-tape machine bandwidth, deflector chute possesses characteristic wide at the top and narrow at the bottom (the upper wide width that is generally greater than unloading roller is 1400mm ~ 1600mm, the lower narrow 750mm left and right that is generally).Two problems and above-mentioned characteristic has in use mainly come out:
A) bulk blocking problem: fully mechanized coal face is in caving process, not exclusively controlled due to top board natural conditions, inevitably want some spoils of let-down, and be arranged in the tup of reprinting the hammer mill slip, apart from base plate, be about 300mm, this laminar spoil that just causes a part of thickness to be less than 300mm becomes " fish that has escape the net ", without fragmentation, enters transport courses.The length of these spoil parts reaches 800mm ~ 2400mm, and width reaches 400mm ~ 1000mm, when through this kind of deflector chute, is very easy to cause blocking in middle and lower part obviously.After blocking occurs, personnel deal with very difficult and danger, and cause all stopping production accidents along the line.
B) due to traditional deflector chute, to connect coal point low, and the gradient is steep, causes coal stream free-falling body to accelerate intense impact deflector chute base plate, and bottom plate wear speed is exceedingly fast; And coal Flow Velocity is available buffer not, the maximum speed that finally can reach with it is fallen on subordinate's sealing-tape machine, easily pounds carrying roller, more seriously makes in flecky the injuring by a crashing object of belt load-bearing surface.And because coal Flow Velocity is uncontrollable without buffering, charcoal piece causes fragmentation when impacting deflector chute base plate, sealing-tape machine and colliding mutually, has reduced piece rate.
Summary of the invention
Easily there is blocking in order to solve traditional " dustpan " type deflector chute in the utility model, and deflector chute base plate is impacted to fierceness, causes the fireballing problem of bottom plate wear, and then propose a kind of belt feeder transfer point V-type buffer slide chute.
The utility model adopts following technical scheme:
A belt feeder transfer point V-type buffer slide chute, comprises some sections of V-type steel plates, between each section of V-type steel plate, by flange, connects, and on described V-type steel plate, has some holes, and abrasion-proof backing block is installed in hole.
The angle of described V-type steel plate is 120 °.
First paragraph top in described some V-type steel plates is connected with arc.
The utlity model has following beneficial effect:
(1) V-type designs without side board, stops blocking and occurs:
From channel section, chute adopts without side board open by design, both wings base plate is V-shaped, angle 120 degree, this open by design characteristic can be blocked bulk spoil nowhere, and experiment discovery, and V-type base plate possesses the well centripetal compliance energy of leading, can be so that the longitudinal landing of strip-shaped materials, the generation of fundamentally having stopped blocking situation.For realizing the on-the-spot unattended duty of sealing-tape machine, ground Automatic Control provides advantage;
(2) high position connects coal, and inclination angle is mild, carries high lump rate:
First paragraph chute adopts a high position to connect coal, makes coal stream accelerate initial contact chute at gravity, has avoided the impact of coal stream to base plate.Base plate adopts level 30 degree inclination angle designs, make the steady crossheading landing of coal levelling, by the friction between coal and cell body, offset part acceleration due to gravity, play good buffer action, and the outlet of chute is that coal flow path direction overlaps with material feeding belt direction towards the service direction of subordinate's sealing-tape machine, the tape speed vis-a-vis that is coal stream is that coal Flow Velocity deducts belt speed, further slow down, reduced coal flowing with time impact with mutually collide, an above high position connects coal, slope landing and low speed and and be with three characteristics, must make former coal cinder damage and decline to a great extent.
(3) wearing and tearing reduce, life:
Because a high position connects coal and slope landing characteristic, coal stream is reduced greatly to chute base plate impulsive force, reduced wearing and tearing, abrasion-proof backing block (accompanying drawing 3) is installed in the punching of chute entire body carrying surface in addition, is more convenient for checking and changes, and the life-span of more traditional chute extends greatly.
(4) protection belt:
Due to coal stream from higher level's belt run quickly from time, the adhesive of raw coal medium sized coal is poor, and the adhesive of smalls is strong, always lump coal is far away when groove to make coal stream, and smalls is nearer, and due to the V-type characteristic of cell body, making angle, bottom is smalls, surface is lump coal, and because slope landing characteristic makes this two-layer no longer mixing, it is anterior for piece rear portion is for last when this just causes coal flowing band, can on the go form rear class belt always lower floor be that last upper strata is the state of piece, when band, lump coal can there is thus one deck carpet sample isolation buffer layer on zone face, add that the low speed that above-mentioned coal stream possesses itself band characteristic, can avoid injuring by a crashing object by actv. protection belt.
