Description

The invention relates to the mining industry and can be used in underground mining with mass blasting of rock mass.

A device for discharging bulk materials is known, comprising a platform for discharging and delivering ore from blocks to transport tanks and an electric drive til.

The disadvantages of the known device is that the device is stationary and is designed to release ore from a single point of release, which leads to disruption of horizontal contact of the ore being produced with overlying rocks, clogging of the ore by these rocks and loss of ore in the bottom of the block.

The closest in technical essence and the achieved result is a device for the release of bulk materials, including at least two feeders, each of which is made in the form of a frame, equipped with a tension and driving drums and a carrier tape and mounted on rails by means of, fixed on it track rollers 21.

The disadvantages of this device include the impossibility of producing a non-uniform, ore varying in composition, and uneven distribution of ore over the block area.

The aim of the invention is to expand the functional capabilities of the device by varying the width of the outlet in the exhaust process depending on the change in the produced material.

The goal is achieved by the fact that in the device, which includes at least two feeders, each of which is made in the form of a frame, equipped with tensioning and driving drums and a carrier tape and mounted on the direction of cich by means of supporting rollers fixed to it, endless and the tension drums are spring-loaded relative to the frame, and each frame is mounted on rails with the possibility of independent longitudinal movement and is equipped with a deflecting roller, which is installed with the possibility of transverse otnosito.pno movement of the frame and frictional engagement with carrier tape.

FIG. 1 shows the device, a general view of FIG. 2 shows the constructive execution of the movement unit of the feeder in the absence of a load on the upper branch of the carrier tape, section A-A, type B.

The device contains feeders 1, which form an outlet 2 for the release of bulk material 3. Each feeder is made in the form of frame 4 and is provided with a carrier endless belt 5, driving 6 and tension 7 drums. The support rollers 8 are fixed to the frame. The tension drums are spring-loaded with respect to the frame by springs 9. Each frame is equipped with a deflecting roller 10 and an actuating mechanism 11. The frames are mounted on the guides 12 by means of support rollers.

The device works as follows.

At the initial moment, the feeders 1 are closed and the outlet 2 between the tension drums 7 is absent, and the bulk material 3 is located on top of the feeders. When the drive drums 6 rotate, the feeders 1 move and create an outlet 2. The working outlet of the outlet is selected from the output of the medium conditioning start. produced material. The feeds 1 move synchronously along the guides 12 on the support rollers 8 and allow the outlet opening to move along the entire length of the discharged area. The movement of feeders is uniform reciprocating.

The movement of the feeders is ensured by the load of the produced material - on the top of the branch of the endless belt 5. At the same time, the frame 4 is shifted to the right or left depending on the direction of rotation of the drive drum, and the endless belt 5 runs off or runs onto the produced ore. .

Permanent reciprocating movement of feeders along the entire length of the discharge area allows maintaining a constant horizontal plane of the produced material throughout the entire discharge. This is important when discharging ore in blocks under collapsed rocks to reduce clogging and loss of ore.

Springing of the tension drums allows changing the width of the outlet hole for the passage of conditioned pieces of minimum and maximum sizes, and their fluctuations intensify the process. In the process of releasing material with a particle size equal to the smaller limit of the conditioned piece, przpkiny 9 is relaxed, the outlet opening is narrowed. With the approach of pieces with dimensions equal to the larger limit of the conditioned piece, the springs 9 are compressed under the action of the arching effect of large pieces and the discharge opening increases.

The production of large oversized pieces is carried out by sledun formation.

When one or both feeders appear in the outlet of a large oversized piece, it is diluted to the sides for the duration of its passage, and then immediately reduced to the establishment of a working outflow discharge from separacTt ' i.

At the moment when the lumpy material hangs, one of the feeders, located under the roof of the suspended output and not having the S load from above, will be deprived of the opportunity to move along the heading 12. To move this feeder following the previous one and keep the working width above the bottom.

10 holes, the actuator 11 deflecting roller 10 presses the endless rotary belt 5 to the clutch 13, which is connected to the roller 8. In this case, the feeder 1 is displaced along guide rails 12 without being loaded from above. After the hangup collapses, the actuator 11 is turned off and the device operates in a predetermined mode.

-: -. . . .

The use of the invention will allow the production of ore from cleaning units of various granulometric composition, to simplify the structures

And the bottoms of the blocks, as well as to reduce the loss and clogging of the ore upon release, by keeping the ore in horizontal contact with the overlying collapsed rocks. P L / I / g. 2 i
