Abstract

The utility model relates to a solid fill-mining conveyor, comprising a machine head part and a machine tail part, a chute is connected between the machine head part and the machine tail part, a plurality of discharge ports are arranged on a trough plate of the chute at interval, a plugboard is arranged on the bottom surface of each discharge port, a hydraulic pressure cylinder for controlling a switch of the plugboard and the size of the plugboard is arranged at outer side of the ledge of the chute, and a scraper blade chain is arranged in the chute. When in working, solid filling material isconveyed from the machine tail to the machine head, the hydraulic pressure cylinder is operated to push and pull mechanized plugboard, the discharge port is opened and the size of the discharge portis adjusted, so as to lead the solid filling material to fall off from the discharge port, when the solid filling material is fully filled with the space below the discharge port, the hydraulic pressure cylinder is operated to push and pull mechanized plugboard, and the discharge port is closed, the scraper blade chain in the chute can scrape the solid filling material below the discharge port levelly, so as to realize the transportation and filling of the solid filling material. The conveyor is suitable for various solid filling materials, and has the characteristics of simple structure, lowinvestment, simple process and easy operation.

Description

Solid filling exploitation conveyer

Technical field

The utility model relates to solid filling exploitation conveyer, is particularly useful for the transportation and the filling of mine solid filling exploitation work plane solid filling material.

Technical background

Along with the continuous exploitation of coal resources, formed many artificial spaces underground, cause subsidence, influence house, highway and the farmland etc. on ground; Discarded object spoil in the coal is piled up on ground simultaneously, forms many hillocks, according to incompletely statistics, about 4,500,000,000 t of gangue that whole nation accumulative total over the years is stacked, larger hillock has 1600, about 1.5 ten thousand km of land occupation ², and accumulating amount also increases with the speed of 1.5～2.0 hundred million t every year.A large amount of stackings of gangue cause the mining area ordinary production and have a strong impact on, environment for human survival is brought very big threat and harm, and bring a series of societies and environmental problem, 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 above problem the solid filling production technique has been proposed, promptly utilize solid filling material such as ground spoil, loess, flyash to be filled in the underground goaf, and realize that the key of solid filling material bashing is with the transportation of solid filling material and is filled to the goaf.Therefore, it is particularly important to develop the solid filling material transportation and the stowage unit of a kind of high efficiency, high mechanization.

Summary of the invention

The purpose of this utility model provides a kind of mechanization simple in structure, efficient, small investment, solves the solid filling exploitation transporter of mine solid filling exploitation work plane.

For achieving the above object, solid filling exploitation conveyer of the present utility model, comprise chain-drive section, drive end unit, be connected the chute between chain-drive section, the drive end unit, be interval with a plurality of discharge ports on the frid of chute, be equipped with plate on the bottom surface of each discharge port, the ledge outside of chute is provided with the hydraulic cylinder of control plate switch and size, is provided with scraper chain in the chute.

Described a plurality of discharge port arranges evenly that from lower end to upper end its spacing is about 3m along the chute of solid filling exploitation conveyer; The disembark distance of head of first discharge port in described a plurality of discharge port is about 1.5m.The hydraulic cylinder that described chute is located at the ledge outside is symmetrical arranged.

Solid filling exploitation conveyer of the present utility model, by the discharge port of discharging filling is set on drag conveyor chute frid, control discharge port open and close is set under discharge port and regulates the mechanization plate of discharge port openings of sizes, hydraulic cylinder at chute ledge arranged outside push-and-pull mechanization plate, chute connects the employing Bolt Connection, can realize the efficient mechanization transportation and the filling of mine solid filling exploitation work plane solid filling material, be applicable to multiple solid filling material, as the filling of spoil, flyash, river sand, loess or mixture etc.It is simple in structure, small investment, and technology is simple, operation easily, transportation is good with filling effect, has practicality widely.

Description of drawings

Fig. 1 is the structural representation of solid filling exploitation conveyer.

Fig. 2 is the cross-sectional view of chute discharge port of the present utility model position.

Among the figure: 1-chain-drive section, 2-drive end unit, 3-chute, 4-discharge port, 5-plate, 6-hydraulic cylinder, 7-scraper plate, 8-scraper chain.

The specific embodiment

Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:

Shown in Figure 1, solid filling exploitation conveyer mainly is made of chain-drive section 1, drive end unit 2, chute 3, chain-drive section 1 comprises motor, chute 3 is connected between chain-drive section 1, the drive end unit 2, Bolt Connection is adopted in the connection of chute 3, to increase the intensity that connects, increase solid filling exploitation conveyer simultaneously in flexible degree vertical, horizontal direction.Be interval with a plurality of discharge ports 4 on the frid of chute 3, a plurality of discharge ports 4 arrange evenly that from lower end to upper end its spacing is about 3m along the chute 3 of solid filling exploitation conveyer; The disembark distance of head 1 of first discharge port of work plane below is about 1.5m, and discharge port 5 is shaped as rectangle, is of a size of 500 * 400mm.Be equipped with plate 5 on the bottom surface of each discharge port 4, and be provided with and be welded on chute frid bottom surface and be suitable for the slideway that plate 5 slides, the ledge outside of chute 3 is provided with the hydraulic cylinder 6 of control plate 5 switches and size, hydraulic cylinder 6 is symmetricly set on the ledge outside of chute 3 both sides, in order to push-and-pull mechanization plate 5, control the open and close of discharge port 4 and the openings of sizes of regulating discharge port, thereby effectively control charging quantity, filling velocity and the filling scope of solid filling material.Be provided with in the chute 3 attal is sent into scraper plate 7 and scraper chain 8 in the discharge port 4.

During work, start solid filling exploitation conveyer, slave Caudad heading transportation solid filling material, operation hydraulic cylinder 6 push-and-pull mechanization plates 5, the size of opening discharge port 4 and regulating discharge port, the solid filling material is fallen from discharge port 4, when the solid filling material fell to expiring 4 times side spaces of discharge port, operation hydraulic cylinder push-and-pull mechanization plate 5 was closed discharge port 4, scraper chain in the chute 3 is wipeed the solid filling material of discharge port 4 belows off, realizes the transportation and the filling of solid filling material.
