Description

(54) SCREW CONVEYOR

The invention relates to a hoisting machine building design, namely to screw conveyors, and can be used for oriented loading of working machines with piece parts.

A screw conveyor is known which comprises a fixed conveyor pipe, a transporting and gripping augers rigidly connected by a shaft movably mounted in a bed, and the product is fed to the gripping auger from the hopper of a flj storage bin.

A disadvantage of the known device is the absence of oriented dispensing of piece goods.

The closest to the proposed screw conveyor includes a casing with loading and unloading windows and a bunker transporting a spiral placed in a casing, a detail conductor and an ejector of parts C2.

The disadvantage of this device is the low productivity of the piece-by-piece dispensing of parts, since a maximum of one detail can be performed per revolution of the transporting helix.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by the fact that in the screw conveyor, including the casing with the boot and unloading. The zing windows and the bunker transporting the spiral placed in the casing, the details of the conductor and the ejector of parts, the details of the conductor are made in the form of at least two grooves-streams in the shell, and the casing has magnetic elements placed along the entire length of the grooves; inter-turn spiral segment attached to the transporting helix.

FIG. 1 shows a conveyor section; in fig. 2 is a fragment of the section A-A-ya of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows the arrangement of the ejector from the transfer helix.

The screw conveyor includes a hopper 1, a drive chain 2, a transporting coil 3, which is attached one-end to your drive

25 with a reflective cone 4, placed inside the casing 5, and a detail conductor 6, made in the form of two springs of streams. The casing 5 has magnetic elements 7 placed throughout

30 the length of the grooves. In the area of unloading

window 8 on the transporting helix 3. located in the form of an interturn spiral segment ejector 9.

Screw kbnveyer works as follows.

Parts buried in the hopper 1,; slide along its inclined bottom to the turns of the transporting helix 3, pass through the inter-turn space inside it and fall on the reflective cone 4, which directs the parts mainly to the helix coils 3. Voroshy, they fall into interturnal space and transported on coils to the orienting conductor b ,. where, being in the zone of action of the magnetic elements 7, they sink, orienting themselves, into the grooves-grooves of the component 6 and, resting one end into their walls, a - by the middle part - on the turns of the transporting spiral 3, rise up to the discharge window 8. When lifting in the zone of the window 8, the parts are discharged by means of the ejector 9 into the discharge tray 10.

The invention provides an increase in the productivity of oriented piece delivery of parts from the pile, since during one revolution of the transporting helix into the tray, several parts can be issued depending on the number of grooves-streams in the pipeline, for example, 3.4, etc. In addition, it is possible to perform a device with several unloading trays, i.e. each groove-stream can correspond to a specific tray.
