UA83029C2 - Modulat tillage machine - Google Patents

Abstract

A modular tillage machine comprises a trailing unit, a main frame, supporting wheels, sectional frames with working elements and mechanisms of attaching to the main frame, rollers with mechanisms of adjusting position thereof, a hydraulic cylinder which arranges the sectional frames in the working and transporting position. No less than two sectional frames, not connected between each other, are attached to the main frame by lever and hinged four-link mechanisms, which include longitudinal control-rods, diagonals, stoppers, central control rods, and rotational axles of the supporting wheels on the main frame are fixed immovably, and the hydraulic cylinder connects the main frame with the trailing unit. The rotational axle of the supporting wheels is arranged at the same axis with hinges of connecting the main frame and the trailing unit. Connections of the main frame with the trailing unit and the hydraulic cylinder are made as a three-point tractor mounting. The invention allows using a wheeled stroke, while carrying out transport movements and carrying out a technological process with the modular tillage machine, and also lowering a load onto the working elements when tripping-over a stone or a rhizome.
