FIELD: materials handling facilities. ^ SUBSTANCE: proposed feed pipe contains cylindrical drum or pipe which has great number of inlet holes 8 distributed lengthwise the pipe, screw conveyor 3 arranged coaxially inside pipe 2, first device to provide rotation of pipe around its axis, second device to provide rotation of screw conveyor 3 relative to pipe 2, third device to move feed pipe 1 in crosswise direction, and loose material activators forming projections on outer surface of pipe 2 and arranged on pipe in combination with said inlet holes 8. At least two inlet holes 8 and at least two activators are arranged in each cross section along operating part of pipe 2. Moreover, separate projecting elements are provided on outer surface of said pipe 2 to stir loose material and/or projecting elements arranged, at least partially, at a distance from said inlet holes 8 to force loose material to inlet holes. ^ EFFECT: improved reliability of operation of feed pipe at handling of loose material. ^ 5 cl, 23 dwg |
