FIELD: agricultural engineering, in particular, equipment for sowing of pasty mixture of seeds with nutritive substances. ^ SUBSTANCE: sowing apparatus has hermetically sealed vessel for seed and nutritive substance mixture. Vessel has charging throat with cover, air supply branch pipe and replaceable gauged spray nozzles. Apparatus is further provided with shanks, seed guides and coverers made in the form of chain of disks, which are connected with one another through flexible coupling equipped with spacer. Three middle disks have larger diameter than other disks. Flexible coupling is pivotally fixed at attachment points on shank cheeks. Shanks are attached to frame through hanger composed of four symmetrically arranged tie-rods equipped with damping member. Lower ends of damping members are disposed in telescopic bushings, which are fixed in pairs at right and left sides, at rear and front sides. Seed guides and shanks are positioned independently with regard to one another. ^ EFFECT: improved uniformity of seed embedding depth and seed spreading and, correspondingly, increased yield. ^ 3 cl, 4 dwg |
