Combined normal and precision sowing wheel for seed drills

摘要

Combined normal and precision sowing wheel for a seed drill, a precision sowing wheel being connectable to the sowing shaft by means of a positive and clamp-like connection and the precision sowing wheel and the normal sowing wheel being mounted next to one another as separate parts in a sowing housing on a common sowing shaft, the precision sowing wheel being connectable to the normal sowing wheel by means of a coupling pin lockable in at least two operating positions by locking elements, and the precision sowing wheel and the normal sowing wheel each having, in addition to their middle bore, a further bore in which the coupling pin is arranged. In order decisively to simplify the locking elements and the production and assembly of the sowing wheels, the locking elements (10) are made in one piece (Figure 1). <IMAGE>
