The invention refers to a pressurised fertilizing device, which includes a primary feeder device (2), in a front and backward moving fertilizer chute for transport of fertilizer to a fertilizing pipe (7) via an opening designed in the wall of the tube (8a) at which the named primary feeder device (2) is designed to in its foremost end position connect the opening (8a) and form a part of the given wall as well as a second, in the given pipe (7) front and backward moving feeder device(8) for further transport of fertilizer in the named pipe. In order to ensure locking of the first feeder device (2) in its foremost turning position when the pressing piston (8) presses the fertilizer forward in the pipe (7) and at the same time brings about operationally safe and simple hydraulic manoeuvring of the feeder device, the following invention is proposed, that both of the feeder device's hydraulic cylinders (3, 9) are directly connected parallel to a common pressure generating circuit so that, with a pressure direction in the given pressure generating circuit the first feeder device (2) is influenced to perform its feeding movement at the same time as the other feeder device (8) is affected to perform its return movement and vice versa with a reversed direction of pressure in the pressure generating circuit, as well as that a device in inserted which blocks the first feeder device's return movement until the other feeder device has completed a determined part of its feeding movement.<IMAGE> |
