Beschreibung
Zusammenfassung:The invention discloses a device for seed-metering, comprising a seed-metering housing with a first seed-metering housing and a second seed-metering housing, and a seed-metering disc provided with two groups of negative-pressure-holes, each group comprising a plurality of negative-pressure-holes arranged along a circumferential direction. The first seed-metering-housing is provided with an outer negative pressure cavity and a first seed outlet for matching with negative pressure holes away from the rotation center of the seed-metering-disc on an inner side close to the seed-metering-disc, and a first seed inlet penetrating into an inner space on an outer side. The second seed-metering-housing is provided with an inner negative-pressure-cavity and a second seed outlet for matching with negative-pressure-holes close to the rotation center of the seed-metering-disc on an inner side close to the seed-metering-disc, and a second seed inlet penetrating into an inner space on an outer side.
