CULTIVATOR Russian patent published in 2016 - IPC A01B33/08 A01B71/00 A01B39/08 

FIELD: agriculture.

SUBSTANCE: invention relates to cultivators and tillers, designed for soil cultivation in home gardens or farms. Cultivator comprises working member (1) with reducer (2), steering handle (5), and power unit (7) comprising internal combustion engine (8) and gear (10) to output shaft coaxially connected via clutch with input shaft (3) of reduction gear (2). Cultivator is equipped with damper of vibrations of power unit (7) made, for example, in form of elastic elements (17), through which power unit (7) interacts with reduction gear housing (2) with possibility of its reciprocal-rotary oscillating motion relative to reduction gear (2) in plane perpendicular to axis of rotation of output shaft of internal combustion engine (8). Elastic elements (17) are made and installed relative to power unit (7) and housing with possibility of their elastic deformation in direction of vibrations of power unit (7). Presence of said damper of vibrations provides protection of steering handles (5) of vibration loads created by internal combustion engine (8), as well as protection of steering handles (5), transmission and internal combustion engine (8) of impact loads generated by working element (1) in processing of uneven and non-homogeneous sections of soil.

EFFECT: furthermore, such design improves working conditions of operator, higher efficiency of soil treatment and longevity of transmission and internal combustion engine (8).
