FIELD: agriculture. ^ SUBSTANCE: invention relates to agricultural engineering but is to be utilised in various industries for bulk materials dosage. The seeding apparatus is composed of a housing on one side thereof there being a drive (such as a stepping motor) mounted with the other side covered with a lid. The drive shaft interacts with the seeding apparatus shaft positioned inside the housing. On the shaft there is a reel mounted on the butt-end thereof on the drive mounting side there being a recess provided for intended to accommodate the bearing outer race. The other butt-end of the reel is shaped to match the bearing inner race. Inside the housing on the drive side there is an embossment provided for intended to match the bearing inner race; in the lid there is a recess provided for intended to accommodate the bearing outer race and windows for dust removal. In the housing there are also upper and lower windows arranged for the bulk material passage towards the seed duct and a window for dust removal. In the upper window of the housing two curtains are mounted, fabricated of a resilient and elastic material. ^ EFFECT: proposed seeding apparatus is noted for stability of operation, improved reliability and durability. ^ 2 cl, 6 dwg |
