TILLAGE TOOL FOR RIGS FORMATION Russian patent published in 2008 - IPC A01B13/02 

FIELD: agriculture.

SUBSTANCE: tillage tool purposed for rigs formation consists of plate feed, leg and hob which is set on the axes of the bearings. The plate feed is a rotation body made up of the body and crown which are connected by means of the concave surface; it also contains two journaled perpendicular semi-axes capable of rotating and being fixed by means of ears. The application of the invention allows for forming rigs without mixing soil layers. Consequently, moisture in the lower soil layers remains that is very important in the regions with insufficient level of moisture.

EFFECT: change of angle of slope of the plate feed towards the direction of rotation and angle of slope to vertical ensures the possibility to regulate the height and width of the rig.
