Description

The invention relates to a mining transport, in particular, to devices for the production of ore.

The purpose of the invention is to increase the reliability of operation and to ensure the regulation of ore output on the conveyor. The drawing shows a device for producing and transporting ore.

The device contains a conveyor 1 installed in the excavation, a main 2 and an additional 3 vibrating feeders with a main 4 and an additional 5 working plates on the sled 6 and 7. Between the runners of the sled below the working plates 4 and 5 there is a conveyor 1 Between the edges 8 and 9 of the discharge sections of the working plates 4 and 5 and the conveyor belt G 1 there are gaps h and hj. Between the plates 4 and 5 there is a window with height h ,.

The vibrating feeder 2 is equipped with an ore flow shutoff 10, and the conveyor belt 1 under the slab 4 is provided with a protective plate 11 (shown by dotted lines).

Vibration actuators, 12 and 13 are associated with slabs. The device is equipped with a protective baffle plate 14, Vibration feeders 2 and 3 are installed in series above the conveyor 1. The distance between the conveyor and the edge of the unloading areas of the working plates of the vibrating feeders h, H.h is variable and decreasing in the direction opposite to the direction of ore transportation. The distance h is chosen from the condition of the free passage of the conditioned piece of ore under the edge 8, the Minimum distance h is chosen from the condition of the free passage of the protruding parts of the conveyor belt (for example, scraper under the edge 9,

Neighboring vibratory feeders can be located with the possibility of placing the discharge part of the plate of one vibro feeder 3 under the protection of the plate 4 of another vibro feeder 2. This can control the total length of two units (and hence the volume of broken rock mass), as well as the distance hj.

In order to prevent the rock mass from the working pins 5 of the vibrating feeder 3 from falling onto the conveyor belt under the working plate 4 of the vibrating feeder 2, the device is equipped with a switch 10 in the form of a metal plate hinged to the working plate 4

at its top. If necessary, the overlay with the help of servomechanisms can be opened, turning around the hinge towards the working plate 4,

. The height of the outlet window h between plates 4 and 5 is equal to the distance between the lower edge of the discharge end of the vibro-feeder 2 and the conveyor belt 1, i.e.,. In addition, the height h may be less than h.

If there is no floor 10 (or if it breaks) to avoid

ore from the vibrating plate 5 on the conveyor under the vibrating plate 4, the conveyor belt is covered with a removable protective plate 11, which is located above the conveyor belt

And under the working plate 4. The plate 11 can be installed on the guides on the slide 6.

The device works as follows.

After penetrating the transport formation: 15, the main reserves of the chamber are burned and repulsed, while the visor-ceiling 16 with a capacity of 3-5 m remains unbroken. After installation

conveyor 1 and vibratory feeders 2 and 3 bring down part of the ceiling on the working plates. In this case, the broken mountain mass can be divided into two zones: the mountain mass shipped by the vibrating feeder 2. (zone I), and the mountain mass shipped by the vibrating feeder 3 (zone II). The release of the rock mass is carried out sequentially. First, the mass in the zone of action is shipped

vibrating feeder 2, and then ship the mountain mass, located on the side of the goaf. This release sequence can be carried out with complete shusk.

ORE from zone I, and then from. of zone II, when the ostagmental bulk of the piles supported by the vibrating feeder 3 is actually shipped, as well as when alternating the output of ore from zones I and II, is not excluded

There is simultaneous operation of vibrating feeders

. In the proposed method of release, the load from the mass is redistributed between the vibrating feeders, which increases

reliability of the device.

At the same time, ore losses in the mined-out space are reduced by increasing the length of the device and by forming a natural barrier.

zone II, in which the ore, remaining relatively stationary, prevents large masses of ore from zone I from rolling into the developed space,

But as the parts of the ceiling-cap are broken, and when the work front is shifted, the device is moved with the help of a winch installed in the transport excavation. The conveyor is shortened by partial dismantling and moving it also with the help of a winch.
