Abstract

This report for Utility Model refers to an improvement introduced in the configuration of drag plates sets installed in a conveyor of the redler type, in a closed circuit circular duct, used for transportation of bulk products, more specifically, for handling vegetable grains and agriculture seeds, such as soy, corn, wheat, rice, oats, barley, coffee and other products. Its major application is for drying and warehousing facilities for grains, which use vertical circular silos, bulk warehouses and also other handling processes employed by agricultural properties, cooperatives, agro-industries and similar industrial facilities. It comprises an innovative replacement of plates of the “U” type currently used, which do not allow the reversing of the change of direction. This improvement to the conveyor corresponds to a new characteristic drawing of the drag plate (8) and respective attachment (9) to the chain, which allows reverting the change of direction of the conveyor chain (1) enabling the sprocket wheel (4) to be used on both sides of said chain along the extension of the circuit. This characteristic allows performance of the conveyor with more flexible configurations as its major benefit, and further reduces the quantity of material used to manufacture the drag plates.

Claims

1. A device comprising:

A tubular conveyor throughout its extension, wherein the transport is done by means of a roll chain (1) composed by metal plates with back reinforcements (9) and carrying plates made of UHMW (8) located peripherally near a semicircle or profiles in “

D”

in opposition originating central spaces or openings (10) and clockwise and anti-clockwise changes, in the same plane, formed by corners provided with indented wheels (4).

2. A device comprising:

a grain conveyor with two independent drag plates (8), forming a pair, symmetrically assembled on the attachments (9) of a conveyor chain (1) with the outlying format of the drag plates (8) is similar to a semicircle with an outer diameter smaller than the internal diameter of a duct (5), forming two gaps or openings (10) in relation to an imaginary axis passing through the center of the semicircles with the gaps correspond to the thickness of a sprocket wheel (4) that is attached to said conveyor chain, with the plates (8) bilaterally mounted on the conveyor chain (1), allowing for a free movement and engaging of the chain with the sprocket wheel (4) on the upper and lower sides of the chain.

3. A device according to claim 2 further comprising:

having each plate is individually fixed to the corresponding attachment (9) by means of setscrews (11).

4. A device according to claim 2 further comprising:

enabling clockwise and anti-clockwise flows.

5. A device according to claim 2 further comprising:

enabling turns of the sprocket wheel in a closed circuit.
