An apparatus for separating grains of seed or fertilizer includes a separating device having a housing with a housing base for mounting on an agricultural machine. A releasable housing cover is arranged on the housing base in a releasable manner. A grain sump receives the grains introduced into the housing interior to be separated out. A rotatable separating disc having openings is positioned in the housing interior. An overpressure region is formable in the housing cover on a front side of the separating disc during operation, such that a flow can form from the overpressure region through the openings to the rear side of the disc and grains separated can be localized near the openings. A grain transfer device includes a feed, a wall bushing and an outlet, wherein the separated grains can be introduced through the feed into the bushing and discharged from the housing interior through the bushing.

Apparatus and method for separating out grains of seed, fertilizer or the like

A single-grain sowing device comprising: a drum rotatable about an axis of rotation, a cavity formed in the drum, wherein an end face of the cavity is delimited by a sowing disc, in which multiple sowing holes are arranged on a notional circular path at a distance to each other, a body arranged in the cavity, rotatable about an axis arranged at a distance and parallel to the axis of rotation, with one part of the surface thereof resting against the sowing disc such that, when the sowing disc rotates, same temporarily seals a respective passed sowing hole on the inside, wherein the body can be rolled out on an outer casing surface surrounding the cavity, and a pressure spring, wherein the pressure spring presses the body against the casing surface.

Device for single-grain sowing

A coulter with a coulter disc for delivering agricultural materials into soil along one direction F of travel, a height measuring apparatus which is located in the region of the coulter disc for measuring a penetration depth Tof the coulter disc into the soil, a coulter holder for swivelling holding of the coulter disc on a coulter frame and height setting relative to the coulter frame, the penetration depth T of the coulter disc being controllable/adjustable depending on the measured penetration depth T.
