Device for transporting and compacting comminuted materials

Abstract

A device for transporting and compacting comminuted materials, particularly organic plant materials, comprises belt conveyors, located convergently to each other. Transporting and compacting carriers are made from a material accepted for contact with food products, particularly with tobacco material. According to the invention, both belt conveyors, situated at an angle (α, β), respectively, relative to the horizontal direction, are equipped with uniform, continuous and endless belts. Elements increasing the adhesion and preventing sliding between the driving rollers and the surface of the belt are located on the inner surface of the belts of both conveyors, i.e., on the side, facing the driving rollers, while elements increasing the adhesion, preventing sliding between the belt and the transported material, are located on the external surface of the belt.

1 . A device for transporting and compacting comminuted materials, such as organic plant materials, comprising belt conveyors, located convergently to each other, the transporting and compacting carriers of which are made from a material accepted for contact with food products, characterized in that both belt conveyers, situated at an angle relative to the horizontal direction, are equipped with uniform, continuous and endless belts, elements increasing the adhesion and preventing sliding between the driving rollers and the surface of the belt are located on the inner surface of the belts of both conveyers, i.e., on the side facing the driving rollers, while elements increasing the adhesion and preventing sliding between the belt and the transported material are located on the external surface of the belt.  
   
   
       2 . A device according to  claim 1 , characterized in that the elements located on the inner surface of the belt are recesses spaced along the whole belt, across its whole width and arranged in parallel to the motion of the belt.  
   
   
       3 . A device according to  claim 2 , characterized in that the recesses located on the inner surface of the belt are V-shaped.  
   
   
       4 . A device according to  claim 1 , characterized in that the elements located on the external surface of the belt are square or rhomboidal recesses or dimples, repeatably distributed on the whole surface of the belt, one of the diagonals of every dimple/recess being arranged in parallel to the motion of the belt.  
   
   
       5 . A device according to  claim 1 , characterized in that the inclination angle of the belt conveyors relative to the horizontal direction is in the range from 0° to 30°.  
   
   
       6 . A device according to  claim 1 , characterized in that the ratio of the width to the total length of the belt made from polyester and-/or polyolefine is in the range from 1:25 to 1:8.5.  
   
   
       7 . A device according to  claim 1 , characterized in that the carriers are made from a material accepted for contact with tobacco material.
