| 摘要 | The sowing depth and pressure applied to the unit (6) comprising a seeding coulter (4) and a pressing cylinder (5) of a seed drill (1) may be easily adjusted by means of a drag rod gear (40) linked to an intermediate frame (14) and provided with drag rods (7) that converge in the direction of travel (8). The intermediate frame (14) is in turn hinged to the joints (16) of frame (3), seed hopper (2) or of a leading or supporting machine by means of a supplementary drag rod gear (41). The supplementary drag rod gear (41) may swivel. The sowing depth may thus be easily adjusted. The convergence of the additional drag rod gear (41) may also be adjusted or switched, and the additional drag rod gear (41) may also swivel. The sowing depth and the pressure applied on the seeding coulter (4) and pressing cylinder (5) of all units (6) of a seed drill (1) or sowing machine may thus be easily adjusted from a central location. | ||||||
