TRACTION MOBILE DEVICE FOR CIRCULAR SOIL TREATMENT Russian patent published in 2017 - IPC A01B51/00 A01B69/00 A01B49/00 A01B3/68 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building and can be used for agricultural operations on circular fields mechanization. Traction mobile device for circular soil treatment comprises central support, telescopic boom and working carriage. Telescopic boom inner section is connected with the possibility of longitudinal displacement and locking in extreme positions with telescopic boom intermediate element. Working truck is connected with telescopic boom outer section by hinge with two degrees of freedom and is equipped with steering mechanism and process equipment. Working truck comprises diagonally arranged self-aligning and drive wheels, drive to move along the telescopic boom axis. Working truck is made with possibility to vary track in radial direction. Working truck steering mechanism is engaged with drive controlled wheels vertical axes via chain gear. Platforms with power plants in form of hydraulic motors coupled with drive wheels via chain gears are fixed on vertical axes. Telescopic boom intermediate element is equipped with support wheels and winch. Intermediate element support wheels track is equal to track of working truck in transport position. Winch is equipped with rope guide plate. Winch shaft is connected with vertical shaft sprocket by chain transmission, and drum made with possibility of chain transmission disconnection is connected with working truck by cable. On vertical shaft splines a rod is installed made with possibility of vertical displacement and locking in extreme positions. Rod lower part is made rectangular and is articulated with central support. Central support is made in form of grip and is equipped with spring-loaded latch.

EFFECT: such design solution is aimed at higher efficiency, mobility, reliability and simplified design of traction mobile device.
