Description

The invention relates to the mining industry, and is especially related to the cleaning of spillage formed at the outlets, and can be widely used in other areas of technology where bulk and lumpy material is loaded and unloaded. The purpose of the invention is to simplify the design while reducing downtime of transport equipment. Formed in the process of loading due to inaccurate installation of the trolley under the hatch device of the ore pass or for another reason, spilling, passing through the roar 4 and rolling down on the inclined ramps 7 of chamber 6,

. The invention relates to the mining industry, mainly to the means used when loading trolleys or conveyors under the outlet openings of the ore chutes, and can be widely used in other areas of technology, such as railway transport.

The purpose of the invention is to simplify the design while reducing downtime of transport equipment.

The drawing shows schematically the proposed device for cleaning spills from under the outlet openings of the ore pass.

In the loading unit spill transport equipment in the loading chamber. 1 with a loading hatch 2, a trolley 3, a screen 4 mounted from I-beams on which rails 5 are fixed, a chamber 6 located below the rail tracks, formed by inclined ramps 7 with bunkers 8. In the lower position of the bunker, its front and side walls are like would be a continuation of the inclined ramps 7 that serve as chutes, along which the spillage rolls into the bunker 8. On the wall of the chamber 6 opposite to the hatch 2, two guides 9 are installed in the form of shaped channels, in the cavity of which two pairs of roller bearings 10 and 11, mounted on the rear or side walls of the bunker 8. The upper ends of the guides are Y-shaped with sections 12 and 13, the first of which fits to the trolley 3 and is located above it, and the second is oriented in the direction of the flexible traction element (cable) 14, connected at one end with the axis of the roller bearing 10 and secured at the bottom of the bunker 8, and the other with a winch

• 15. The latter, together with the electric motor 16, is mounted on brackets 17 fixed to the production walls.

20, the device operates as follows.

After installing the trolley 3 under the hatch 2 of the ore pass, the loading process begins. Formed during loading due to the inaccurate installation of the trolley under the hatch. By royalism or for another reason, waking up, passing through the roar 4 and rolling down the inclined ramps 7 of the chamber 20 .6, accumulates in the bunker 8. As the latter is filled in

the electric motor 16 and the winch 15 with the help of a cable I4 lift the bunker 8 along the guides 9. When the bunker approaches the U-shaped part of the guides 9 fixed at the mouth

bunker roller bearings 11 are pushed into section 13 by gravity, and roller bearings 10, fixed to the bottom of bunker 8, under the action of the winch 15, enter section 12 and, as they rise, lead to rotation of the bunker with respect to the axis of roller bearings 11. 45 Hopper overturns. 8

Claims (1)

Claim five A device for cleaning spills from under the outlets of the ore-landing, including a bunker installed in the guides to trap spills, connected to a lifting mechanism 10, different in that that, in order to simplify the design while reducing transport equipment downtime, the guides are arcuate, their upper ends are Y-shaped, the bunker is installed on the inner side of the arcuate guides on two pairs of roller bearings, and the lifting mechanism is connected by a flexible traction element to the bottom of the bunker.
