Central dosing feeder for pneumatic distribution machine i.e. sowing machine, has blocking valves actuated independent of each other, where valves cover partial area of dosing bodies, and actuating device projected into housing

摘要

The feeder (1) has dosing bodies (5, 6) arranged in a housing (4), rotatably driven and formed as a cell wheel. The housing is arranged below a storage container ,and a blocking mechanism that is arranged above one of the bodies and blocks supply of material in the storage container to the cell wheel. Blocking valves (8, 9, 10) are actuated independent of each other, and cover a partial area of the dosing bodies. Blocking valves are formed as blocking rotary slide valves, and an actuating device (12) is projected into the housing assigned to the valves (9, 10).
