industries, thermal power plants. It allows you to increase the efficiency of averaging and reduce material spillage through buckets. A device for overloading and averaging bulk materials contains a rotatable tubular working body 3 mounted on the undercarriage with discharge windows in which buckets 6 are installed. The lateral walls of the latter are connected with transporting spirals 7 and 8 fixed to the inner side of the working body between which the rear wall is located each bucket. An annular chamber 10 of U-shaped cross section with radial partitions is fixed at the end of the working organ, and protective covers placed inside the chamber of the tray 12 and on the lateral sides are fixed on the undercarriage. In the process, the bulk material in the stack is loosened by the ripper, taken by the buckets and guided by transporting spirals to the receiving conveyor 13. 1 h. item f-ly 5 ill.

The invention relates to devices for handling and averaging materials, such as coal or ore, previously poured into a stack in layers with different contents of the useful component, and can be used in the coal, mining, coking, chemical industries, thermal power plants and others.

The purpose of the invention is to increase the efficiency of averaging and reduce material spillage through buckets.

FIG. 1 depicted proposed device, general form; on FIG. 2 - view BUT in fig. one; in fig. 3 - section B — B on FIG. one; in fig. four - section B — B on FIG. 3; in fig. five - section G — T on FIG. four. Device for overloading and averaging

The bulk materials contain a chassis support consisting of a self-propelled chassis 1 with a supporting metal structure 2, on which is mounted a tubular working body 3 with a drive 4 and a ripper 5. On the tubular working body 3 there are windows in which buckets b are placed, with each side wall which are associated with two flat transporting spirals 7 and 8, attached to the inside of the working body. At the ends of the tubular working body 3 posted mechanisms 9 of the bobbin type. At the discharge end of the working body fixed annular chamber 10 U-shaped section with radial partitions 11 for receiving movable bulk material, which is then unloaded on the tray 12, mounted on the suspension support, and on the conveyor 13. To prevent premature emptying of the annular chamber 10 on the suspension support safety guards 14 are installed on the inside of the chamber in its side zone.

A guide plate 15 is also attached to the metal structure 2 along the entire length of the working member, which occupies a middle or lower position depending on the movement of the device in one or the other direction.

The device works as follows.

Moving along the rails located on both sides along the stack of bulk material, the device hits the pile 16 and collapses it with the ripper 5. Moving in the direction indicated by arrow I and rotating along arrow II, the working body 3 with its buckets 6 scoops the collapsed material, lifts it up and pours out of the buckets inside the working body 3. The transporting spirals 7 and 8, rotating together with the working body, move the material to the end of the working body, the material is poured into the cells of the annular chamber 10, the latter unloads it on the tray 12, from which the material enters the conveyor 13. In the process of rolling and translational movement, an additional, almost perfect, averaging of the material is achieved, which improves its quality.

When moving the machine in the direction indicated by arrow II, the guide plate 15 is located in the middle position. When the working movement of the machine in the opposite direction, the direction of rotation of the working body does not change, the flap 15 is lowered downwards, which ensures the filling of the bucket 6 with the loose material scooped by them. All other operations are repeated without rearrangement and rotation of the machine.
