Abstract

1. A screw of a flexible screw conveyor, including a spiral rigidly connected to a folded screw surface, which is such that, in order to expand technological capabilities, the spiral is made in the form of an extended torus filled with pressure by a working agent. 2. A method of making a screw of a flexible screw conveyor, including the execution of a pocket-camo on a flexible sleeve along a helical line, characterized in that a chamber in the form of an extended torus is pulled into the pocket-cam, the working agent is pressed into it and the resulting as a result of the expansion of the chamber auger to obtain the required pitch. 3. The method according to claim 2, in that, in order to obtain an Archimedean screw surface, the screw is turned out. t ts9 SL 00 with fi.CH

Description

The invention relates to a hoisting and transport machinery, namely, devices for transporting materials, in particular, to sciral conveyors with flexible screws operating in flexible pipes, used for transporting bulk, liquid and other similar materials, as well as methods for their manufacture,

Known screw flexible screw conveyor containing a metal spiral, enclosed in an elastic shell with a longitudinal ridge, directed inside the spiral C.

The most efficient to offer is a screw of a flexible screw guide, including a spiral that is rigidly connected to a folded screw surface 21.

The disadvantage of the known screw is its low flexibility, and

also a lot of weight due to the use of a metal spiral.

The closest to the present invention is a method for manufacturing a flexible screw conveyor, including the execution of a pocket-pocket 2 on a flexible sleeve along a helix.

The disadvantage of this method is that it does not allow the manufacture of augers of large D5 meters.

ABOUT

The purpose of the invention is the expansion of the technological capabilities of the screw of a flexible screw conveyor,

The goal is achieved

the fact that in the screw of a flexible screw conveyor, which includes a spiral rigidly connected to the folded screw surface, the spiral is made in the form of an extended torus filled with pressure by the worker: agent, and in the method of manufacturing the screw it is flexible: on a screw conveyor,

including the execution on the flexible sleeve along the helix of the pocket-camo, in the first, the chamber is drawn in the form of an extended torus, the working agent is fed into it and the tensioner is stretched, resulting in

tata chamber expansion screw to semi- | required step. In addition, to obtain an Archimedean screw surface, the screw is inverted.

Fig. 1 shows a sleeve of matter or a similar material which is converted by means of folds into a screw surface; in fig. 2- a long torus that is converted into a spiral during the manufacture of the screw; in fig. 3 — screw with constant screw surface; FIG. 4, screw with Archimedean screw surface; in fig. 5 is a section A-A in FIG. four,

The auger of the flexible screw conveyor contains a screw surface made of sleeve 1 on which a screw line is applied (for example, in the form of a groove) of the pocket-camo 2. The screw also contains a spiral made in the form of a chamber of a flexible extended torus 3 filled under pressure by the worker an agent.

The torus 3 is manufactured by twisting the flexible tube from both ends and connecting the inverted ends.

The screw according to the proposed method is manufactured as follows.

A flexible material, such as fiberglass, is sewn to sleeve 1. A hemlock of fiberglass is sewn on its surface along a helix to obtain an extended pocket-camouflage 2. In pocket 2, they pull chamber 2, which is made in the form of an extended torus 3. Then chamber under pressure serves air. Torus 3, trying to straighten out, is forced to accept (as it is fixed on the sleeve 1 along a helix) the shape of a spiral of the greatest diameter and the smallest length.

To obtain a screw with an Archimedean screw surface, the resulting screw is inverted by changing the direction of its winding.

The invention will allow to expand the technological capabilities of the screws, to grumble the screws of almost any diameter with a large transverse bending and a lower weight. fug. , 2

Claims (3)

1. The screw of a flexible screw conveyor, comprising a spiral rigidly connected to a folded screw surface, which is explained by the fact that, in order to expand technological capabilities, the spiral is made in the form of an extended torus filled with a working agent under pressure. 2. A method of manufacturing a screw of a flexible screw conveyor, comprising performing on a flexible sleeve along the helical line of a drawstring pocket, characterized in that a drawer is pulled into a drawstring pocket in the form of an extended torus, a working agent is fed under pressure and the resulting expansion is stretched chamber auger to obtain the required step. 3. The method according to claim 2, characterized in that, in order to obtain an Archimedean helical surface, the screw is turned out.
