Description
Technical Field
The utility model relates to a coal mine equipment, in particular to can press down dirt colliery inclined coal bunker that has a down dip.
Background
At present, in order to improve the mining efficiency and benefit and shorten the production preparation period of a mine and a mining area in the mining of coal mine enterprises, the main rubber conveying lane and the mining area rubber conveying lane of the mine are mostly arranged in the same coal seam, rubber belt conveyors of the working face rubber conveying lane, the mining area rubber conveying lane and the mine rubber conveying lane are directly overlapped without buffer space, so that one conveyor belt transportation is formed, and various adverse factors influencing the working face production and various hidden dangers of a coal transportation system are caused.
Firstly, cause the heavy load of rubber belt conveyor along "one dragon" of rubber belt conveyor transportation to shut down easily, influence rubber belt conveyor's safe operation and rubber belt conveyor's life.
Secondly, the production of the working face is greatly influenced, once any link of the rubber belt conveyor in the one-line system fails, the rubber belt conveyor behind the failure point must be stopped for waiting, and balanced production cannot be realized. Thirdly, the unplanned shutdown easily causes hidden troubles to the normal circulation of a working face, roof support and the like. The common method for solving the problems is to increase the capacity of the coal bunker and improve the continuous coal supply capacity of the coal bunker, but is limited by the site and the height, and the enlarging and heightening space of the coal bunker is limited.
In addition, coal dust pollution is serious when coal is transported from a coal bunker by a mining area rubber belt conveyor. In the prior art, a spraying mechanism is arranged above a rubber belt conveyor at intervals, and dust removal and fall are realized by spraying. The spraying is more, the water content in the coal is large, and the surrounding field is muddy; less spray, poor dust removing and falling effect.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the prior art not enough, provide one kind and take up an area of for a short time, capacious, and outwards carry coal raise dust few, the spraying demand is little can press down the colliery coal mine declination bunker.
In order to realize the purpose, the underground coal mine underground inclined coal bunker capable of suppressing dust comprises a coal bunker main body, wherein the top of the coal bunker main body is provided with an opening, and the lower part of the coal bunker main body is provided with a coal outlet and a flashboard, and is characterized in that: the coal bunker main part is enclosed by arc board and bottom plate under last arch bar, both sides wall, the thickening, coal outlet includes preceding coal outlet and back coal outlet, and the two distributes in order along adapted mining area rubber belt conveyor direction to be equipped with the flashboard respectively, the upper rubber belt of adapted mining area rubber belt conveyor is in proper order through preceding coal outlet and back coal outlet, 40-60 degrees contained angles are personally submitted with the level to coal bunker main part central line.
By the design, under the condition of the same height difference, the capacity of the coal bunker can be doubled, coal powder and coal dust are arranged below the coal flow conveyed by the belt conveyor for the matched mining area, most small coal blocks cover the coal powder and the coal dust, and when the belt conveyor for the mining area works, the raised dust is less, and the dust removal spraying amount is less.
Preferably, sliding plates are respectively arranged between the upper arch plate and the thickened lower arc plate and between the thickened lower arc plate and the bottom plate. By the design, the coal can be prevented or reduced from accumulating and caking at corners.
The utility model discloses can press down dirt colliery inclined coal bunker has and takes up an area of fewly, and the storehouse holds greatly, and the little, the little advantage of spraying demand of output coal stream raise dust, is fit for each big colliery and uses.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In the first embodiment, as shown in fig. 1 to 3, the downward-inclined coal bunker for a dust suppression coal mine comprises a coal bunker main body 1, wherein the top of the coal bunker main body 1 is open, and the lower part of the coal bunker main body is provided with a coal outlet and a gate 2. The method is characterized in that: coal bunker main part 1 encloses by last arch bar 11, both sides wall 12, thickening lower arc 13 and bottom plate 14 and becomes, coal outlet is including preceding coal outlet 3 and back coal outlet 4, and the two distributes in order along the 5 directions of adapted mining area rubber belt conveyor to be equipped with the flashboard respectively, coal outlet 3 and back coal outlet 4 are gone out in proper order to the upper rubber belt 6 of adapted mining area rubber belt conveyor 5, 40-60 degrees contained angles are personally submitted with the level to 1 central line L of coal bunker main part. Preferably at a 45 degree angle.
As shown in figures 1 and 3, when in use, the coal powder or the pulverized coal slides downwards along the thickened lower arc plate to form a powder pile 8 on the thickened lower arc plate 13, then flows out from the front coal outlet 3 and falls on the upper rubber belt 6 of the belt conveyor 5 of the matched mining area.
The coal 10 with good fluidity and large jumping property rolls down rapidly on the surface of the powder pile 8, flows out from the front coal outlet 4, falls on and covers the coal powder 9 and the coal dust on the upper layer of the adhesive tape 6.
The above is merely an example of the specific embodiments of the present patent, and the present invention includes but is not limited to the above embodiments, and any coal bunker device described in the claims of the present invention falls into the protection scope of the present patent.
