The invention relates to agricultural machine-building, in particular to planting apparatuses of planting machines. The planting apparatus comprises two tangential disks, one of which is rigid and the other is elastic and contacts four pressure rollers in the area of keeping seedlings by outer surface thereof and two releasing rollers in the areas of putting in and freeing the seedlings by internal surface thereof. The pressure rollers are disposed in pairs at the edges of the bases of two spring-loaded swinging sectors of a triangular shape, which are pinned radially on a pivoted arm, the rotational axis of which coincides with the rotational axis of the disks. The releasing rollers are disposed on two L-shaped brackets, the rotational axis of which also coincides with the rotational axis of the disks. On the internal surface of the spring-loaded swinging sectors supporting surfaces of the arched shape are arranged, which contact the hinged arm. The construction proposed allows raising the reliability and improving the quality of operation of the planting apparatus. |
