Technical field
The present invention relates to coal mine machinery field, be specially a kind of downhole gangue transhipment crushing system.
Background technology
Coal is as the main energy sources of China, and it plays extremely important effect in socio-economic development.Gangue is the solid waste that coal is discharged in driving, exploitation and washing process, the digging gangue that downhole gangue produces when mainly comprising stone head driving, and from top board, base plate and extraction comes in being clipped in coal seam rock intercalation spoil etc. in coal mining process.Colliery is through exploiting for many years, and pile up like a mountain for discarded spoil, not only occupies a large amount of soil, and in spoil, contained sulfide understands atmosphere pollution and water source after distributing, and causes serious consequence.The easy oxidation by air of pyrite contained in spoil, liberated heat can impel contained coal weathering so that spontaneous combustion in gangue.The smog that gives off an unpleasant smell and be harmful to during spoil burning, causes neighbouring resident to suffer from chronic bronchitis and the increase of asthma probability, and trees can not normal growth, and the crops underproduction etc.Hillock is by rain drop erosion, and also often make the channel aggradation in neighbouring river, river is polluted.In addition, hillock or Gangue also may produce landslide accident, cause casualty accident.Therefore, it is broken that storage is carried out to spoil in down-hole, can realize the utilization of resources, can protect again to environment.
Summary of the invention
In view of above-mentioned deficiency, the invention provides a kind of downhole gangue transhipment crushing system, can carry out fragmentation, accumulating to spoil in down-hole, save processing cost and time, reduce labour intensity, system architecture is simple, practical.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of downhole gangue transhipment crushing system, comprise drop-bottom car, hole unloaded at the end, waste bin, spoil disintegrating apparatus, air duct, cyclone dust collectors and belt conveyer, described drop-bottom car and the end, unloaded to cheat and be flexibly connected by track, described waste bin be positioned at the end unload hole below, discharging opening bottom waste bin is connected with spoil disintegrating apparatus, described cyclone dust collectors are connected with spoil disintegrating apparatus by air duct, and described belt conveyer is positioned at the side of spoil disintegrating apparatus and the below of cyclone dust collectors.
Further, described spoil disintegrating apparatus also comprises an elevating conveyor, and the end of this elevating conveyor is positioned at the top of described belt conveyer.
Further, the described end, unloads hole and is provided with a charging sluice gate with waste bin is middle.
Further, described waste bin also comprises a discharging lock, be positioned at the discharging opening of waste bin, comprise fixed fence, portable fence, double track and switch handle, described fixed fence is fixed in the discharging opening of waste bin, described double track is located at fixed fence two ends, and described portable fence is flexibly connected with double track, and described switch handle is flexibly connected with portable fence.
Further, described fixed fence is multiple, equidistant placement.
Further, described portable fence is connected with double track by roller.
Further, described portable fence is multiple, equidistant placement.
Further, described fixed fence is equal with the width of portable fence, and equal with the spacing of respective fence.
Further, described portable fence also comprises the connecting rod of a Vertical dimension, and this connecting rod is fixedly connected with described portable fence.
Further, connecting rod one end of described portable fence is dentation end, and this dentation end and described switch handle are connected with a joggle.
The invention has the beneficial effects as follows, this system can carry out accumulating to the spoil produced in coal production process, unloads below, hole and is provided with independent waste bin, stored by the spoil of quantity inequality, saved cost of transportation the end of at; Being provided with discharging lock in discharging opening bottom waste bin, is horizontally openable, prevents discharging opening because normally opening closedown by spoil weight, simultaneously, because discharging lock adopts the structural design of fixed fence and portable fence, the size that discharging opening is opened can be adjusted flexibly, thus control spoil amount; Below discharging opening, spoil disintegrating apparatus is directly set, the spoil that Convergency fracturing stores, has greatly saved time and labour intensity; Cyclone dust collectors are directly discharged into after the dust process of collection on belt conveyer, mix with spoil material, without the need to processing it again.Compared with transporting shattering process with existing gangue in coal mine, this overall system architecture is simple, easy to use, substantially increases accumulating and the crushing efficiency of spoil material, in the transhipment shattering process of gangue in coal mine, have practicality widely.

Detailed description of the invention
For making above-mentioned feature and advantage of the present invention become apparent, special embodiment below, and coordinate institute's accompanying drawing to be described in detail below.
The present embodiment provides a kind of downhole gangue to transport crushing system, as shown in Figure 1, this system comprises drop-bottom car 1, hole 2 is unloaded at the end, waste bin 3, spoil disintegrating apparatus 5, air duct 7, cyclone dust collectors 8 and belt conveyer 9, material to be transported to the end by track and to unload hole 2 by drop-bottom car 1, the end, unloads below hole 2 and connects waste bin 3 by charging sluice gate, discharging opening bottom waste bin 3 is connected with spoil disintegrating apparatus 5 downwards, cyclone dust collectors 8 are connected with spoil disintegrating apparatus 5 by air duct 7, belt conveyer 9 is positioned at the below of the elevating conveyor 6 of spoil disintegrating apparatus 5 and the below of cyclone dust collectors 8.
The discharging opening of waste bin is provided with the discharging lock 4 of a horizontal switch, and as shown in Figure 2 and Figure 3, it is made up of fixed fence 41, portable fence 42, connecting rod 43, switch handle 44 and double track 45.Fixed fence 41 equidistant placement is in the discharging opening of waste bin 3, double track 45 is located at the two ends of fixed fence 41, portable fence 42 is equidistantly connected by connecting rod 43, roller-coaster can be passed through on double track 45, the width of these two kinds of fence is equal, and equal the spacing of respective fence, like this can intact open and close.Containing gear on switch handle 44, be connected with a joggle with the dentalation of portable fence 42, move left and right this portable fence 42 by rocker switch handle 44, thus open and close discharging lock 4.
