This seed drill is of the type comprising at least one drum which is driven by a continuous rotary movement about a horizontal axis close to the ground and which comprises peripheral chambers, in which the grains are concentrated before being deposited. Each chamber (34) of this drum (1) is associated with a closing flap (35') which itself is associated with means permitting its automatic opening when the corresponding chamber reaches the position in which the grains are to be released. Under the main hopper (13), there are fixed secondary hoppers (12) which are each associated with a distributing drum, and the connection between the main hopper (13) and the secondary hoppers (12) is made by means of a set of slides (14-15), by virtue of which it is possible to displace the secondary hoppers longitudinally and transversely in relation to the direction of travel of the tractor carrying the seed drill. <IMAGE> |
