Agricultural attachment e.g. plough, for use with e.g. tractor, has wireless signal transmission device and generator including permanent magnet, which moves during vibrations of attachment to convert vibrations into voltage by induction

摘要

The attachment has electronic sensors to output signals corresponding to measured operating parameters of the attachment. A wireless signal transmission device transmits the signals to a control unit. A generator supplying power to the sensors has a spring system with flat springs and a permanent magnet (31) which moves linearly relative to a fixed coil when the attachment vibrates to convert the vibrations into voltage by induction. An independent claim is also included for a mobile agricultural machine with an agricultural attachment.
