Pneumatic distribution machine i.e. seed drill, for distributing seeds, has pressure sensor attached to conveyor line and detecting pressure acting on line, and dosing device switched on and/or off if line attains preset air pressure

摘要

The machine has a dosing device (2) associated to a storage container (1) and feeding a material accommodated in the storage container into a pneumatic conveyor line (7) using a feed-in device (5), where the line is pressurized by a compressor (6). A pressure sensor (13) is attached to the conveyor line and detects the pressure acting on the line. The sensor is connected to an electronic evaluation device and to an on-board computer, which outputs a signal while obtaining adjusted pressure value. The dosing device is switched on and/or off if the conveyor line attains a preset air pressure.
