Description

one

The invention relates to devices for loading and unloading bins and can be used as overloading in open pit mines.

A device for reloading bulk materials is known, comprising a hopper with screens, feed mills, and end face unloading platforms, a crusher and a main conveyor located under the bunker 13

The disadvantages of the known device are its complex structure and low productivity, which in the conditions of a developing career leads to an insufficient capacity of the unloading point of the auto-. : mobile transport.

The purpose of the invention is to improve the design and increase productivity.

This goal is achieved by the fact that the outlet window of the crusher and the feeder are successively located above the main conveyor, and the equipment is equipped with side receiving troughs and adjacent side discharge chambers installed in the bunker.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view,

The device contains an unloading zone 1 of motor transport with two face 2 and two side 3 unloading platforms and a bunker with two compartments 4 and 5. On compartment 4 there are two screens 6, except

0, it is equipped with an autonomous outlet window 7 and is adjacent to the front discharge pads 2. The bunker compartment 5 has two lateral inclined receiving troughs 8, adjacent to the side discharge pads 3. The receiving troughs 8 are inclined towards the crusher 9 installed at the end bunker compartment 5 equipped with a feeder 10

0 to feed the rock mass from the hopper to the crusher. The outlet port 7 of the bunker compartment 4, the feeder 10 and the outlet port of the crusher 9 are successively located above the main conveyor 11.

During operation of the device, dump trucks with a rock mass are fed to the unloading areas 2 and 3 of the unloading area 1. Two of them are unloaded.

0 into the bunker compartment 4, the other two into compartment 5, the mountain mass, which is directed into compartment 4 of the bunker, falls on screens, where it is divided into oversize and sub-groove product. Oversize enters the compartment 5 of the bunker and, together with the rock mass coming from the side discharge pads 3 through the receiving chutes 8, is fed by the feeder 10 to the crusher 9. The sub-product of the jpes discharge port 7 of the bunker compartment 4 enters the cargo-carrying canvas of the main conveyor 11. crushed through the outlet window of the crusher 9 also enters the main conveyor 11, Spilling through structural leaks between the belt of the feeder 10 and the walls of the bunker compartment 5 enters the load-bearing canvas conveyor 11,

The use of the present invention improves the performance of the transfer point.
