摘要：

The drill has a multiple switch (20) comprising a connection bar (25) with several connections (26a-d) for distributor outlets (14). The switch also has a switch bar (27) with connections (28a-d) for distributor sleeves (22) and outlets (29a-d) leading to the seed bin (4). The switch is operated by a power cylinder and the connection bar forms part of an open-bottom bowl arranged in the seed bin. The switch bar has several lengthways slots and is guided by a screw riding in these slots off the connection bar (25). The outlets (29a,d) are holes whose diameter is sufficient to throttle the air flow and provide air resistance in the sleeves. The outlets can also comprise suitably waisted pipe connections.
