ZEMLYAKOV'S CULTIVATOR FOR SOIL RIPPING AND ROOT CUTTING OF WEEDS WITH MECHANISED DRIVE, CARRIED BY HANDS AND SHOULDER BELT Russian patent published in 2009 - IPC A01B33/00 A01B1/06 

FIELD: agriculture.

SUBSTANCE: cultivator has lighter autonomous drive. Master shaft of drive with axial slit opening is detachably connected to slit teeth of the first end of straight steel extension shaft. Shaft is installed in fixed protective-support pipe. Pipe is detachably connected with its first end to drive body, and by its second end - to reducer body. The second slit end of straight steel extension shaft is detachably connected to input shaft of reducer. Spidery cutting tool is detachably joined to output shaft of reducer. Tool has solid base of disk-like shape, with diametre D. Along peripheral part of base there are balanced bracket-like beam plates with width h. Plates are directed along axis of disk-like base, relative to one of two its surfaces, opposite to reducer body, and provides for axial length ψ of cutting tool. In center of disk-like base there is a through form opening, by means of which it is installed and fixed at outlet shaft of reducer. Bracket equipped with support wheel is detachably and movably fixed to reducer body. Width h of bracket-like, beam plates is arranged from 1/7 to 1/2 of value relative to overall diametre D1 of cutting tool. Axial length ψ of tool is arranged with value from 1/2 relatively to width h of single bracket-like beam plate up to 3/4 relatively to overall D1 diametre of cutting tool. Angle between axis of straight extension steel shaft and axis of outlet shaft of reducer is equal to 90°.

EFFECT: in case of such cultivator design quality of soil cultivation increases, besides cultivator has low weight, may be easily held in hands in process of working operations performance, is easily disassembled and assembled and may be easily transported in road bag.
