TILLER Russian patent published in 2009 - IPC A01B33/02 A01B13/08 

FIELD: agriculture.

SUBSTANCE: tiller consists of frame with facility for coupling with power module and working tools rigidly secured on frame by means of holders. The working tools have curvilinear working surface, a curvilinear breaking edge and reverse-double-pointed chisels. Curvature of working surfaces faces axis of symmetry of the tool. The frame is made in form of a front and back longerons and side beams installed at an angle to longerons. The holders of working tools are secured on the frame symmetrically relative to lengthwise axis of the tool and in pairs. Distance between lengthwise-vertical planes of identical holders of neigbour working tools on the beam is at ratio to the distance between transverse-vertical planes led through a heel of the front and point of the following working tool as (500-700):(50-150). Angle between axis of each side beam and lengthwise axis of the frame is within ranges of 50-70 degrees. Distance between front holders of working tool fastened on neighbour beams is in interval of 700-1000 mm. The tool is equipped with a roller, hinged on the frame and kinematically connected to it by means of device regulating depth of tilling. A vertical pole is assembled in the centre of the front longeron. The upper part of the vertical pole is connected to the central part of the back longeron and its ends by means of braces thus forming isosceles triangle.

EFFECT: facilitating upgraded quality of soil treatment and reliability of process.
