SUBSURFACE CULTIVATOR FOR CREATION OF GRASS COVER BETWEEN ROWS OF PERENNIAL PLANTS Russian patent published in 2015 - IPC A01B39/16 A01B49/02 

FIELD: agriculture.

SUBSTANCE: subsurface cultivator for creation of grass cover in between rows of perennial plants comprises a frame (1), support wheels with regulatory mechanisms, the subsurface blades (14 and 15), the shoe (13), the chisel (16) and racks (2, 3 and 4). The front rack (2) is fastened to the frame (1) with two L-shaped plates and clamps. On the front side of the front rack (2) a rod scraper is mounted. Each of the two rear racks (3 and 4) is formed integrally with toe steps (11 and 12) and represents a right and left half portions of one shoe configuration. The toe steps (11 and 12) are mounted in the direction of extension length of the subsurface blades (14 and 15). The working width of the blades (14 and 15) in operation is 2400 mm, and the span angle is 80є. The toe steps (11 and 12) are fixed to the frame (1) via supporting sleeves (9 and 10) made of a vertically positioned plate bent in the middle part at an angle of 60є, and in front perpendicular to it, there are plates of rectangular shape. The rear beam of the frame (1) is pivotally mounted to two rods (17 and 18) with a roller (19) consisting of a central axis, rotating in the hubs, on which the U-shaped profiles are fixedly mounted. Transfer of the roller (19) to the operating and transporting position is performed by means of a hydraulic cylinder (20).

EFFECT: creation of grass cover of weeds between rows of perennial plants, reduction of negative impact of propulsion tractor units on soil, reduction of flow of moisture from the soil.
