<p>PROBLEM TO BE SOLVED: To provide a seeding machine in which a grooving depth and a soil covering width are interlocked and changed in conformity to hardness and softness of a field, and soil can be covered with the amount of earth and sand suitable for a seeding groove depth.SOLUTION: A seeding machine is liftably provided with a seeding unit 8 for feeding seeds accumulated in a seeding hopper 1 from a feeding unit 2 to a field at the rearward of a traveling vehicle body 9, is provided with a grooving unit 7 for forming the groove part with the seeds getting therein below the seeding unit 8, and is provided with a soil covering plate 6 for covering and burying soil in the groove part formed by the grooving unit 7. The seeding machine is configured such that the change of the soil covering width of the soil covering plate 6 and the change of a grooving depth of the grooving unit 7 can be interlocked and operated by a soil covering actuator 12, which operates to deepen the grooving depth of the grooving unit 7 by increasing a pressing force of the soil covering plate 6 on a hard soil surface, and to shallow the grooving depth of the grooving unit 7 by decreasing the pressing force of the soil covering plate 6 on a soft soil surface.</p> |
