The dosing device has at least two dosing wheels which can be coupled selectively to the dosing shaft by swivel-mounted coupling elements. The coupling elements are formed as swivel pawls (27) and in the coupling position engage with an entrainment nose (30) into at least one recess of the drive shaft (12) and/or with parts connected to same. In the uncoupled position the swivel pawl bears on the frame of the dosing housing. Where hollow shafts are associated with the dosing wheels these shafts are formed integral with the wheels. The drive element of one dosing wheel can be connected integral with the hollow shaft.
