DISTRIBUTOR Russian patent published in 1997 - IPC

FIELD: agricultural engineering; drills. SUBSTANCE: drive shaft 2 is installed in hopper 1 coaxially with feed opening 8 of bottom 7 Head 3 of lever 4 provided with trunnion 5 is connected with shaft 2 by means of thread. Nut 13 fixes head 3 relative to shaft 2. Blade 6 rests flat on bottom 7 crossing the edge of feed opening 8. Blade 6 is mated with trunnion 6 through vertical hole. Flange 12 with skirt 9 resting on bottom 7 is made on shaft 2. Port 10 opening to bottom 7 is made in skirt 9. Port 10 engages with blade 6 through its vertical edge. With shaft 2 rotating, blade 6 under action of seeds, thrust against vertical edge of port. Surface of blade 6 will take position along chord of feed opening 8. Seeds, moving along surface, will pass in flow to edge of feed opening 8 through port. Skirt 9 and flange 12 will prevent getting of seeds, not entrained in flow, into feed opening 8. Amount of seeds can be changed by changing fixed position of lever 4 relative to shaft 2. EFFECT: enlarged operating capabilities. 3 dwg
