TRACTION MOBILE DEVICE FOR CIRCULAR SOIL TREATMENT Russian patent published in 2018 - IPC A01B33/06 A01B33/08 A01B51/02 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, namely to tools, used, for example, in circular fields. Traction mobile device for circular cultivation of the soil comprises a central support with an arrow connected with the possibility of rotation relative to the support through a vertical shaft with a splined joint and hinge, operating trolley, a chain drive sprocket of the operating trolley, connected by means of a bearing support with a vertical shaft. Vertical shaft is further provided with a coupling adapted to be connected to the sprocket and is connected to the motor, mounted on the boom, by means of the drive of the vertical shaft, and configured to disconnect from the drive of the vertical shaft. Central support is made in the form of a reducer, the drive shaft with a coupling is connected to a vertical shaft, and the driven shafts are connected to the drills.

EFFECT: such a design solution provides increased productivity, mobility and economy of the traction mobile device due to possibility of its installation at any point of the treated surface.
