Mineral fertiliser distribution and drilling machine - has containers mounted on transport vehicle at field edge in which is driveless extraction worm to transfer material

摘要

The extraction worm (3) issues into an outer pipe connection (4) and has coupling adapters (5.1) to which a transfer worm (8) is connectable by means of corresp. coupling adapters (5.3, 5.4). This latter worm is enclosed in a delivery tube (7) with issue aperture (12) and is driven pref. from the application vehicle. The delivery tube with the transfer worm are retained by a limitedly elastic suspension (13), and are pivotable between work and transport positions, being easily mountable on the application appts. (11). The centering and pick-up parts for the pipe connection and the delivery tube together with the shafts of the extraction and transfer worms are funnel-shaped and conical. USE/ADVANTAGE - For agricultural purposes for applying mineral fertiliser and making drills for sowing, using an arrangement which is favourable from a cost aspect, is fully mechanised, without the need for intervention by the driver of the application vehicle.
