A device for separating out grains of seed, fertilizer, or the like, having a separating device that operates according to the positive-pressure principle, the separating device comprising: - a housing that is formed with a housing base to be mounted on a frame or on a seed line of an agricultural machine and a housing cover that is detachably arranged on the housing base for opening and closing a housing interior; - a grain sump configured to receive grains of seed, fertilizer, or the like that are introduced into the housing interior and are to be separated out; - a separating disc that is rotatably mounted in the housing interior and has an arrangement of openings; - a positive-pressure region that can be formed, during operation, in the housing cover on a front side of the separating disc such that a flow can be formed from the positive-pressure region toward the rear side of the separating disc through the openings, whereby separated grains can be localized near the openings or adjacent thereto; and - a grain transfer device that is composed of a feed, a wall duct, and an outlet on the housing cover, it being possible for the separated grains to be introduced through the feed in the wall duct after being released from the separating disc and to be guided out of the housing interior by same via the outlet, a grain receiver being arranged in the vicinity of the feed that defines a feed opening for a grain inlet that is connected to the wall duct and detachably arranged on the inside of the housing cover (4, 30); characterized in that a forced grain scraper is arranged in the vicinity of the feed, that is detachably arranged on the grain receiver and is configured to assist in releasing separated grains from the separating disc. - a housing that is formed with a housing base to be mounted on a frame or on a seed line of an agricultural machine and a housing cover that is detachably arranged on the housing base for opening and closing a housing interior; - a grain sump configured to receive grains of seed, fertilizer, or the like that are introduced into the housing interior and are to be separated out; - a separating disc that is rotatably mounted in the housing interior and has an arrangement of openings; - a positive-pressure region that can be formed, during operation, in the housing cover on a front side of the separating disc such that a flow can be formed from the positive-pressure region toward the rear side of the separating disc through the openings, whereby separated grains can be localized near the openings or adjacent thereto; and - a grain transfer device that is composed of a feed, a wall duct, and an outlet on the housing cover, it being possible for the separated grains to be introduced through the feed in the wall duct after being released from the separating disc and to be guided out of the housing interior by same via the outlet, a grain receiver being arranged in the vicinity of the feed that defines a feed opening for a grain inlet that is connected to the wall duct and detachably arranged on the inside of the housing cover (4, 30); characterized in that a forced grain scraper is arranged in the vicinity of the feed, that is detachably arranged on the grain receiver and is configured to assist in releasing separated grains from the separating disc.
