Abstract

The invention relates to hoisting machines and can be used, for example, in the mining industry when driving openings. The goal is to enhance operational capabilities and increase reliability. The spiral-screw conveyor includes a flexible casing (BG) 1 with a loading nozzle 2 and a transporting spiral 3 located in it and a drive 4 mounted on the frame. In the place of unloading on the frame is placed emphasis, made in the form of a cam (K). GK 1 is made with discharge openings 7 with lids 8. On the latter, levers 9, 10 with rollers 11 are fixed at the ends for interaction with K, on the surface of which a groove recess is made. In the longitudinal movement of the HA 1 relative to K, the latter interacts with the roller 11 of the lever 9 or 10, depending on the direction of movement of the conveyor and, turning the cover 8, opens or closes the discharge openings 7, respectively. f-ly, 2 ill.

Description

The invention relates to hoisting machines, namely to spiral-4o-screw conveyors, and can be used, for example, in the mining industry when sinking workings and mining operations.

The purpose of the invention is to expand the operational capabilities and increase the reliability of the conveyor.

FIG. schematically shows a spiral-screw conveyor, plan; in fig. 2 is a view A of FIG. one; in fig. 3 - section BB on

FIG. 2

t The spiral-screw conveyor consists of a hard casing 1 with a loading nozzle (2 and transporting it, spiral 3 and drive 4 mounted on the frame 5. On the latter, in place of unloading, there is a stop Step 6. The flexible casing 1 is made with discharge windows 7 with covers 8. On 1 cover panels 8 are fixed levers 9 and 10 with rollers AND at the ends for more reliable interaction with the cam 6, on the surface of which a slot groove 12 is made .

The covers 8 are connected by a flexible casing 1 by means of a threaded joint 13, which can be multi-use. The position of the spiral-screw conveyor in: the space is fixed by means of guide rollers 14 mounted on the axles with the possibility of rotation of the rollers 15. In the course of movement of the spiral-spiral conveyor, the receiving conveyor 16 is placed. The spiral-spiral conveyor operates: as follows.

: Bulk material, for example, hearth of a sort: from a combine, is fed into the loading port of the conveyor 2 and moves trans-: with the porting helix 3 to the place of unloading on the receiving conveyor 16. When the flexible casing 1 is longitudinally displaced relative to the cam 6, roller AND lever 9 or 10 depending on the direction of movement of the conveyor and turning

the cover 8, respectively, opens or closes the discharge openings 7, in the case of opening of the bulk material, for example, rock transported from the bottom of the mountain is unloaded at the discharge point on the receiving conveyor 16. Due to the fact that the distance from the bulk material discharge point to the receiving one the conveyor 16 to the place of development of the rock in the bottom and loading it into the loading nozzle 2 of the conveyor is constantly changing from the minimum at the beginning of the development of the bottom to the maximum in the bottom of the slab (room-pillar system of development) abutment-cam 6, whereby the opening is produced unloading windows 7 is selected closest to slaughter. The cam 6, located in the zone between the levers 9 and 10, ensures reliable interaction with them in the longitudinal movement of the spiral-screw conveyor in mutually opposite directions. Making the connection 13 of the cover 8 with the flexible casing 1 threaded, for example, multiple-use, provides sealing of the discharge port 7 by tightly pressing the cover of the conveyor 8 of the cover 8 while tightening the latter along the thread.
