UPROOTING DEVICE Russian patent published in 2019 - IPC A01G23/06 

FIELD: machine building.

SUBSTANCE: invention relates to the forestry machine building, in particular to the stumps uprooting devices in forest clearings and burns during the reforestation. Device consists of frame 1, support plate 2, working body in the form of two-armed lever, in which lower part the rooter bits 3 are mounted, the rack and pinion mechanism 4, gear wheel 5, vertical axis of rotation 6, the rooter bits rotation hydraulic cylinders 7, the rack and pinion mechanism movement external hydraulic cylinder 8, gripping mechanism, consisting of sections 9, made two-level and with different lengths for the stump guaranteed girth. Sections position changing is controlled by means of the hydraulic cylinder 11 by turning of the double-arm levers 10 in the hinges 12. Frame 1 is made in the form of inclined rack-frame, which is integral with the support plate 2. Rooter bits 3 are pivotally connected to the frame 1, which upper arm is connected to the frame by the hydraulic cylinders 7. Device is made rotatable on the vertical axis of rotation 6 around the stump due to the rack and pinion mechanism 4 movement, which is engaged with the gear wheel 5, and the external hydraulic cylinder 8.

EFFECT: this rooter device implementation allows the stumps uprooting within the each of their boundaries, eliminating the stump pulling together with the ground, as well as the unit maneuvering around the stump, and therefore reduces the harmful effects on the soil and increases productivity.
