The utility model provides the agricultural machine field with a cotton seed bed seed drill, mainly characterized in that a plurality of vertical and transversal cutting knives are arranged on one side of a piece-cutting plate, a plurality of raised heads are distributed on one side of a aperture-making plate, a plurality of seeds discharging flutes are arranged on one side of a seeding plate with a plurality of seeding holes distributed in the seeds discharging flutes. The piece-cutting plate, the aperture-making plate and the seeding plate can be separated, or the piece-cutting plate and the seeding plate are arranged back to back on the same plate body, or the aperture-making plate and the seeding plate are coplanarly arranged on the same plate body, or the piece-cutting plate and the seeding plate back to back arranged with the aperture-making plate and the seeding plate coplanarly arranged on the same plate body. The hair bundles of a seeds discharging brush are correspondingly consistent with the distance and numbers of the seeds discharging flutes. A plurality of seeds apertures can be made on the seed bed for one time through pressing the aperture-making plate, a plurality of nutritional clods can be cut on the seed bed through pressing the piece-cutting plate, and the seeds discharging brush can be utilized for seeding in every seed aperture for one time, with the advantages of obviously enhancing the efficiency of aperture-making, piece-cutting and seeding, greatly reducing the labor intensity of the cotton planters, and the like.
