Joint structure of the instrument, and method for subjecting a structure of instrument to transition between a position of use in the field and a transport position in road.

摘要

A structure of tool has a structure of a car for attaching to a vehicle and wheels for supporting the frame for movement over a surface of the earth.A pivot structure is alternately mounted in the structure of the car and a set of lifting structure is coupled to the pivot through a range of displacement.A toolbar is installed on a set of elevation.The set of displacement move the toolbar to front as it is moved from the position of use in the field to the transport position.The wheels are mounted on the arms to swing to move the wheels into a transport position more closely.All motion is carried out by actuators such as hydraulic cylinders, to automate the process, making it fast and easy.
