FEED MIXER AND DISTRIBUTOR Russian patent published in 1996 - IPC

FIELD: agricultural engineering. SUBSTANCE: feed mixer and distributor has hopper 1. Augers 2 and 3 are arranged longitudinally in the hopper. Upper augers 2 are positioned along the side walls of hopper 1, and discharge auger 3 is located on the hopper bottom. There is discharge conveyor 4 in the front part of one side wall of hopper 1. Discharge auger 3 has a discontinuity of its screw over discharge conveyor 4, and its windings on the ends opposite of the discontinuity differ in direction. Hollow shaft 5 of discharge auger 3 is provided with built-in air conduit 6. The inlet end of the air conduit protrudes from the front wall of hopper 1. Shaft 5 of discharge auger 3 has perforation holes near its winding, and it is provided with cross partition 8. The partition is located behind the perforated part of the shaft. Air conduit 6 is pipe 9 with upward-directed guiding diffuser 10. Edges of outlet port 11 are contiguous with the internal surface of shaft 5 in the area of perforation. The free end of pipe 9 is gaged, and this free end is mounted for rotation in partition 8 of shaft 5. Diffuser 10 is provided with sealing 12 around the edges of outlet port 11. The inlet end of pipe 9 of air conduit 6 is provided with rigidly attached locking plate 13 with bolt 14 screwed in the front wall of hopper 1. The inlet end of pipe 9 of air conduit 6 is in communication with pipe 15 for pressure delivery of gaseous medium. EFFECT: less energy-intensive process; higher feed mixing quality. 3 cl, 3 dwg
