COMBINED TILLAGE TOOL Russian patent published in 2007 - IPC A01B49/02 

FIELD: agricultural engineering, in particular soil tillage equipment.

SUBSTANCE: tillage tool has frame with hitching device, disk batteries positioned at an angle to transverse line of tillage tool, and tines with hoes. Disk batteries are equipped with supporting devices, each being formed as disk mounted on one or both ends of battery and provided with shell. Disk with shell has smaller diameter than battery disk. Shell is positioned at outer side of disk battery. Shell of supporting device is formed as truncated cone mounted with its greater base on disk. Diameter of cone exceeds maximum diameter of shell. Width of supporting device shell is less than distance between battery disks but greater than height of battery disk sphere segment. Average diameter of shell is less than diameter of battery disk by value equal to tillage depth to which tillage soil deepens during operation of tillage tool. Depth by which hoes deepen into soil may be adjusted by varying height of attachment of hoe tines to frame.

EFFECT: simplified construction and convenient maintenance and operation of tillage tool.
