Abstract
The invention discloses a throwing type filling conveyor, which comprises a handpiece part, a tail part and a chute connected between the handpiece part and the tail part. Waste rock throwing devices are arranged below the chute, and can axially move along the chute, and adjust waste rock throwing speed. A plurality of discharge openings are formed at intervals in the chute. A plug board is arranged on the bottom surface of each discharge opening. Hydraulic cylinders for controlling the switching of the plug boards are arranged outside the edge of the chute. Scrapers and a scraper chain are arranged in the chute. When the throwing type filling conveyor works, solid fillers are transported from the tail part to the handpiece part, a waste rock throwing belt is moved to be below the discharge openings, a speed regulating motor is started, the hydraulic cylinders are operated to open the discharge openings, the solid fillers fall onto the waste rock throwing belt from the discharge openings, the speed of the waste rock throwing belt is changed to adjust a waste rock throwing distance, and when the solid fillers fill spaces behind and below the discharge openings, the discharge openings are closed, and the waste rock belt is stopped to realize the transportation and filling of the solid fillers. The throwing type filling conveyor is simple in structure and easy to operate, and the filling degree, filling speed and filling distance of the solid fillers can be effectively controlled.

Technical field
The present invention relates to a kind of throwing type stowage conveyer, be particularly useful for transport and the filling of the solid filling material being suspended on mine solid filling exploitation working surface hydraulic support afterbody.
Technical background
Along with the continuous exploitation of coal resources, define many artificial spaces in underground, cause subsidence, affect the house on ground, highway and farmland etc.; Discarded object-spoil simultaneously in coal is piled up on ground, forms many hillocks, and according to incompletely statistics, the whole nation accumulative gangue about 4,500,000,000 t stacked over the years, larger hillock has 1600, land occupation about 1.5 ten thousand km
2, and accumulating amount also increases with the speed of 1.5 ~ 2.0 hundred million t every year.A large amount of heaps of gangue mining area of being rivals in a contest normally produces to cause and has a strong impact on, very large threat and harm are brought to environment for human survival, and bring a series of society and environmental problem, be mainly manifested in: occupy large-area farmland, forest land, a large amount of toxic and harmful is discharged during spontaneous combustion, contaminated environment, harm humans safety.
Solid filling production technique is proposed for above problem, namely the solid filling material such as ground spoil, loess, flyash are utilized to be filled in underground goaf, at present, adopt waste filling production technique can realize spoil and do not go up well, thus decrease the pollution of transit link and ground hillock.And the key realizing solid filling material bashing is by the transport of solid filling material and the equipment being filled to goaf.In existing filling machine, use scrapper conveyor to carry out waste filling, cannot realize continuous uniform ground filling, pack effectiveness is low, thus affects production efficiency.Therefore, a kind of efficient, mechanization and the transport of durable solid filling material and stowage unit is developed particularly important.
Summary of the invention
Technical problem: the object of the invention is the weak point overcome in prior art, provides that a kind of structure is simple, efficient mechanical, small investment, reduces a kind of throwing type stowage conveyer that spoil pollutes, realizes the direct filling of downhole gangue.
Technical scheme: throwing type stowage conveyer of the present invention, comprise chain-drive section, drive end unit, be connected to chain-drive section, chute between drive end unit, the frid of chute is interval with multiple discharge port, the bottom surface of discharge port is equipped with plate, the hydraulic cylinder controlling plate switch and discharge port size is provided with outside the ledge of chute, scraper plate and scraper chain is provided with in chute, the interval, below of described chute is hung with multiple moveable throwing cash device, described throwing cash device comprises symmetrically arranged cylinder, be located at the buncher of waste coal outlet belt on cylinder and head roll, the bottom of described chute is provided with can for the slideway throwing the movement of cash device.
Beneficial effect: the present invention by arranging the discharge port of discharging filling on drag conveyor chute frid, the plate controlling discharge port open and close is set below discharge port, at the hydraulic cylinder of chute ledge arranged outside push-and-pull plate, the adjustable speed waste coal outlet belt of impelling spoil is set below discharge port, the working continuously of mine solid filling exploitation work plane solid filling, uniform pack can be realized, be applicable to many kinds of solids filler, as the filling of spoil, flyash, river sand, loess, building waste or mixture etc.Its structure is simple, easily operates, and transport is good with filling effect, can reduce spoil and pollute, have practicality widely.
