PROBLEM TO BE SOLVED: To provide an information and power supply system of an agricultural machine which dispenses with attachment and detachment of a harness for information and power supply when attaching and detaching a work machine mounted on a tractor to perform agricultural work to/from the tractor.SOLUTION: An information and power supply system of an agricultural machine includes a work machine 2 which is mounted on a tractor 1 to perform agricultural work and can be detached from the tractor 1, a transmission unit 16 which is installed on the tractor 1 side, and a reception unit 22 which is installed on the work machine 2. The transmission unit 16 is installed in the vicinity of a connection device 30 which is provided in the rear part of the tractor and enables attachment and detachment to/from the work machine 2. The reception unit 22 is installed in the vicinity of a connector which is provided in the work machine 2 for attachment and detachment to/from the connection device 30. The transmission unit 16 transmits a common electromagnetic wave in which information is put on an electromagnetic wave for transmitting power to the reception unit 22 wirelessly.COPYRIGHT: (C)2014,JPO&INPIT【課題】トラクタに装着して農作業を行う作業機をトラクタから脱着する際に、情報及び給電のためのハーネスの取り付け、取り外しが不要となる農作業機の情報給電システムを提供することを目的とする。【解決手段】トラクタ1に装着して農作業を行いトラクタ1と脱着可能な作業機2と、トラクタ1側に設置される送信部16と、作業機2に設置される受信部22とを有し、送信部16は、トラクタ後部に備えられ作業機2と脱着を可能とする連結装置30の近傍に設置され、受信部22は、作業機2に備えられ連結装置30と脱着するための連結器具の近傍に設置され、送信部16は、電力を伝送する電磁波に情報をのせた共通電磁波をワイヤレスで受信部22へ送信する。【選択図】図2
