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.
