SOIL CULTIVATION DEVICE Russian patent published in 2008 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: soil cultivation device comprising two rows of disks (1, 3, Fig. 1) mounted under an angle of attack, flat cutting working members (2) mounted behind front row disks (1), along their travel lines, and rollers (5). The working members are attached to frame (6). Back row disks (2) are installed between the travel lines of front row disks (1). Back row disks (3) are equipped with working elements (4) installed discontinuously on their periphery. Besides that the distance between the rows of disks (1, 3) is determined according the formula L<B/2tgα, where L is the distance between the disk rows; B is the spacing between disks in a row; α is the angle of attack (the disk positioning angle relative to the device direction of travel).

EFFECT: accumulation and preservation of moisture; protection against erosion, decreased power consumption of soil cultivation process due to increased degree of soil clod pulverisation and decreased tractive resistance of device.
