<p>Machine for the pneumatic discharge of seeds and fertilisers, which is supported on the ground by means of running wheels and which has at least two supply containers which are at least partially separated from one another and in the respective lower regions of which are arranged in series outlet orifices, from which the material located in the supply container is introduced by means of drivable metering elements in adjustable quantities into injectors connected to pipelines and is delivered to the ground via pipelines, the pipelines together with the injectors being connected to at least one blower via at least one air channel, extending transversely relative to the direction of travel in different lengths and having, at their ends located at distances from one another, outflow orifices which open at least partially into seed coulters arranged movably in a vertical plane on at least one crossmember movable in a vertical plane. In order to provide a compact machine of relatively short constructional length for large working widths and with narrow spacings between the rows of coulters, on the one hand, and, on the other hand, the possibility of the simultaneous discharge of different materials, the materials also being depositable at different points, the lower regions of the supply containers, together with the metering elements arranged in the region of the outer orifices, extend respectively transversely in relation to the direction of travel, and in front of the running wheels are located at least two rows of injectors extending transversely relative to the direction of travel. In another embodiment, a further row of injectors likewise extending transversely relative to the direction of travel of the machine is arranged above the running wheels.</p> |
