<p>The seed sowing machine has a container for seeds or fertiliser, with an outlet (45) in its base through which the contents are discharged. A rotor with radial blades (61) is mounted above this outlet, with a narrow gap between the blade tips and container floor. - The rotor is mounted on an eccentric shaft (62). This shaft can be adjusted to vary the width of the gap and so vary the flow of seed or fertiliser.</p> |
