APPARATUS FOR MOVING WORKING MEMBER ALONG SPIRAL PATH Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has rotating radial beam. One end of radial beam rests upon drive running wheel and other end is pivotally connected to immovable central support. Mechanical transmission has flexible coupling free from slippage in first transmission gear, which is fixed on central support. Second transmission gear is mounted for rotation on beam peripheral part. Working member is connected with one of two flexible coupling lines and is mounted on beam for displacement together with flexible coupling line along beam, when it is rotated around central support due to motion of drive running wheel. Apparatus of such construction provides automated spiral tillage of home's or farm grounds of area of up to several hundredths of hectare. EFFECT: reduced labor consumption, increased efficiency and improved quality of cultivated soil. 2 dwg
