Description
Technical field
The utility model relates to a kind of filling coal mining chain type feeding system, is particularly useful for that ground solid filling material is delivered to down-hole coal excavation work plane goaf and carries out filling.
Background technology
Along with the continuous exploitation of coal resources, country has put into effect a series of policy, impels enterprise to change " predation " formula mining type in the past, forces enterprise to improve resource recovery rate, associated resources utilization rate." three times " press the exploitation of coal is the problem that merits attention always, and according to incompletely statistics, the present China only mine main of coal mine under the unified-allocation system " three times " presses coal just to reach 127.9 hundred million t, wherein builds down 94.68 hundred million t, accounts for 69% of stagnation pressure coal amount.Simultaneously, a large amount of solid waste spoils is discharged in the colliery aborning, and traditional mode is directly to be stacked at the face of land, forms the distinctive topographical features in colliery " building " hillock.According to statistics, about 4,500,000,000 t of gangue of whole nation accumulative total stacking over the years at present, larger hillock has more than 1600, and land occupation is about 1.5 ten thousand hectares, and accumulating amount also increases with the speed of 1.5～200,000,000 t every year.In addition, a large amount of flyash of discharging during coal field power plant for self-supply produces, discharging over the years reaches more than 500,000,000 t, and annual newly-increased 5～7,000 ten thousand t.A large amount of stackings of gangue and flyash have caused the mining area ordinary production and have seriously influenced, existent environment of people very big threat and harm have been brought, and a series of society and environmental problem have been brought, mainly show: occupy large-area farmland, forest land, when getting angry, spontaneous combustion discharges a large amount of toxic and harmfuls, contaminated environment, harm humans safety.At these problems, from realizing the purpose of resource and environment coordinated development, seeking rational exploitation and utilization mineral resources, protection face of land building and groundwater resources and protection or transforming the ground surface environment technological approaches becomes inevitable.
With spoil, flyash, loess etc. is filler, realized the exploitation of " three times " pressure coal scale, and the goaf carried out filling, reached the emission treatment problem that improves the coal resources rate of extraction and solve solid waste spoil and flyash, had important practical significance and wide application prospect.But how solids such as spoil, flyash, loess are safe and efficient and be transported to from ground economically apart from the dark down-hole of hundreds of rice, ground, and carrying out goaf filling is a great problem, also is one of principal element that becomes the development of restriction industry technology.
Existing rotary-tray type continuous dosing system, filler drops to the shaft bottom with the pallet on the wire rope, for increasing cornerite, increase frictional force, prevent that wire rope from skidding, the sky wheel diameter that is adopted is very big, and the position that head sheave is set up is also higher, cause feeding system braced structures complexity, maintenance is inconvenient.Meanwhile, the lifting of the middle part of the high position of motor vibration and wire rope all has bigger influence to the stability and the reliability of support; Shaft in wall is installed rolling pulley, maintenance difficult.
Summary of the invention
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, safe and efficient, invest little, the filling coal mining chain type feeding system that result of use is good.
Filling coal mining chain type feeding system of the present utility model, comprise motor, gearbox, carry vertical, pallet, striker plate, aboveground rubber conveyer, the down-hole rubber conveyer, be provided with by the top driven wheel in the described conveying vertical, bottom tooth sector and driving chain constitute the chain transmission mechanism, the motor of driven wheel chain drive, gearbox and aboveground rubber conveyer are located on the well head ground of carrying vertical, described pallet is a Foldable tray, Foldable tray is by scraper plate, form with the slide block that is located at the scraper plate both sides with the fanning strip that scraper plate is chimeric and hinged, the slide block fixed interval of scraper plate both sides is on driving chain, driving chain is located in the chute that scraper plate both sides and striker plate fix, and the bottom of fanning strip is provided with back-up block.
The charging aperture of described conveying vertical and discharging opening are the elliptic cone globoidal structure; Described scraper plate is connected with slide block is vertical.
Beneficial effect: the utility model adopts the chain transmission system, and aboveground solid filling material is delivered to big vertical depth down-hole by tray fold safely and efficiently with material from ground, realizes filling coal mining feed intake conveying machineryization, high efficiency.Changed the size of top driven wheel and bottom tooth sector, the transmission device of chain transmission system is located at well head, rubber conveyer unloads to the pallet of charging aperture decline on the filler artesian well, pallet is transported to the shaft bottom discharging opening by the conveying vertical with filler under the speed limit pulling of chain, under the effect of bottom tooth sector, filler is unloaded to the down-hole adhesive tape conveyor, be transported to the filling mining work plane at last, thereby realize filler transportation to the down-hole, prevented the impact of filler effectively bottom equipment from aboveground.Simultaneously, because the positive and negative placement of fanning strip can both be chimeric and hinged with scraper plate, when existing borehole wall serious wear influence with well one side that feeds intake is used, can fanning strip and scraper plate reverse side is chimeric, and motor reversed, carry filler from the opposite side of carrying vertical, carry prolong one times the service life of vertical thereby make.And improved solid filling material in the solid filling coal-mining technique and be transported to the shortcoming of the existing filling system in down-hole, reduced workman's workload and labour intensity, improved work efficiency from aboveground input, it is simple in structure, and it is convenient, time saving and energy saving to implement, highly effective and safe has practicality widely.
