WORKING BODY OF FLEXIBLE SECTIONAL SCREW CONVEYOR

The working body of flexible sectional screw conveyer is executed in the form of central bushings with screw blades, which are located on the rope through the openings, adjacent bushings are located in the interaction with each other through the balls, which are mounted in the spherical grooves from two ends and are displaced between them in the circular direction for 90 DEGREE . Central bushings with the blades are executed in the form of metal frame, which has a form of bushing and blades, moreover, the balls are in interaction with the grooves of central bushing. The form of the body is similar to the form of central bushing and blades on their external generatrix and bodies of smaller sizes. The body of cylindrical bushing is made of wire in the form of upper and lower rings of wire with incisions, which are rigidly connected together by vertical pins, which are evenly placed in the circle, moreover, their height is lower than the height of bushing, and from two ends of central bushing are horizontally rigidly welded the cross pieces to the upper and lower rings of wire, which are mounted perpendicularly to each other with spherical grooves for the balls. In this case, the depth of grooves is lower than the radius of ball, theoutlines of the body of blades are less than the blades themselves, they are made in the form of grid with rectangular windows, which are rigidly connected together, and the metal body is filled in with the plastic.
