摘要：

The seed distributor for a precision seed drill comprises a rotating, perforated drum (2) mounted in end walls (5) and forming a pressurised chamber with them. The novelty is that there are intermediate walls (8) inside the end walls, forming chambers whose pressure is controlled to be intermediate between the external and internal pressures.
