FORESTRY MACHINE MANIPULATOR Russian patent published in 2022 - IPC A01G23/02 B66C1/68 

FIELD: forestry.

SUBSTANCE: invention relates to the field of forestry. The manipulator of the forestry machine contains a turntable (1), on which an boom (2) with a telescopic handle (4) made of inner (6) and outer sections, and a grip (11) with drive hydraulic cylinders (12) are installed. The boom (2) is driven by a hydraulic cylinder (3), and the telescopic handle (4) is driven by a hydraulic cylinder (5). The position of the inner section (6) of the telescopic handle (4) is driven by a hydraulic cylinder (7). A hydraulic pulsator is connected to the hydraulic system of the forestry machine through a separate section of the distributor. The cavities of the hydraulic cylinder (7) of the position of the inner section (6) of the telescopic handle (4) are connected to the hydraulic pulsator through check valves. To limit the vibrations of the grip (11) in the longitudinal plane, the grip (11) is connected to the outer section (6) of the telescopic handle (4) using a limiter (13) made in the form of a cable, the length of which ensures the vertical position of the grip (11) with a horizontal position of the fully extended inner section (6) of the telescopic handle (4).

EFFECT: simplification of the design and increase in the reliability of the manipulator, as well as expansion of its scope.
