CONTROLLED AGRICULTURAL TOOL WITH BALANCED ROTATIONAL FORCE Russian patent published in 2015 - IPC A01B59/00 A01D67/00 B62D13/00 

FIELD: agriculture.

SUBSTANCE: tool comprises a trailing assembly, a bearing frame, first and second wheel assemblies and at least one actuator. The trailing assembly is made with the ability to connect the tool to the towing vehicle. The bearing frame is connected to the trailing assembly. Each wheel assembly is connected with the ability of rotation to the bearing frame by the corresponding hinge joint. The actuator is made with the ability to rotate the wheel assemblies around the hinge joints in the first direction, applying the first torque, and the rotation of wheel assemblies around the hinge joints in the second direction opposite the first direction, applying the second torque. The magnitude of the first torque and the magnitude of the second torque are substantially equal. According to the second embodiment the bearing frame is connected to the trailing assembly with the ability of rotation. The first and second wheel assemblies are connected to the bearing frame with the ability of rotation by the first and second hinge joints respectively. The tool also comprises the first and second hydraulic cylinders. The first and second hydraulic cylinders extend respectively between the first and second wheel assemblies and the bearing frame and are made with the ability to rotate the first and second wheel assemblies around the first and second hinge joints. The tool has a connecting rod extending between the first wheel assembly and the second wheel assembly. The rod is made with the ability to transmit torque between the wheel assemblies. In accordance with the third embodiment of the tool the first and second actuators are made with the ability of rotation of the first and second wheel assemblies about the respective hinge joints in the first and second directions. The first and second actuators apply the first and second total torques in the first and second directions. The first and second total torques are substantially equal. The tool also has a connecting rod extending between the first wheel assembly and the second wheel assembly, and the connecting rod is made with the ability of transmission of torque between the wheel assemblies.

EFFECT: constructive implementation enables to equalise the rotational force of the bearing frame wheels coming into contact with the ground.
