ABSTRACT:
A distribution device for a single-seed seed drill, comprises a rotatable plate 5 having a peripheral rim 6 and a substantially vertical axis of rotation. The rim 6 has recesses 9 substantially parallel to the axis of rotation and regularly spaced angularly about a circle 10 of the rim, the horizontal section of these recesses and the thickness of the rim corresponding substantially to the size of a seed. The recesses move above a fixed rim 11 in which are provided, directly below the recesses 9 of the rotatable plate, openings 13 for communication with a transport device 14 which leads to a seed drill. A barrier 22, 22' upstream of each opening 13 in the fixed plate, is provided to retain seeds not engaged in the recesses of the rotatable plate. A brake 18, 39 or 52 for the outflow of seeds is interposed between the central portion of the rotatable plate onto which the seeds are fed, and the barrier 22, 23 or 50. In this way, the undesired lodging of two seeds in a same recess is prevented, at the same time that each recess is filled with one seed. The peripheral extent of each seed feeding station can be reduced to the point that as many as twelve feeding stations can be positioned about the periphery of the device, with the result that a seed drill for seeding up to twelve furrows in the ground can be fed.
