  • Patent number: 11445653
    Abstract: The invention describes an equalization mechanism of weight between a central chassis and the side tool-bars of an agricultural machinery and implements, by distributing the weight between the central chassis and the tool-bar frame through pneumatic springs, installed in a slanted position, through specific fixing brackets between the central chassis and the tool-bar frame.

  • Patent number: 11104197
    Abstract: A vertical lifting system for use in farming machines and tools that is formed by a wheel set support arm (01) connected to an articulation support (02) using the pin (04), the articulation support (02) being connected to the wheel hub (05), which is in turn connected to the wheel rim (06). To move the assembly, a hydraulic actuator (07) is connected by the pin (08) to the wheel set support arm (01) and to the articulation support (02) by the pin (09). The height adjustment is provided by the actuator (07), and the mechanism, once actuated, travels around the inside of the wheel rim (06), remaining inside same, and protected in both height adjustment positions of the tool.

  • Publication number: 20200060059
    Abstract: The invention pertains to the peculiar mode of mechanism of multiple integral chassis weight in agricultural machinery and implements, by equalizing the weight of the heavyweight chassis to the lightweight one, ensuring an even distribution of the machine weight on the wheels assemblies, providing perfect and uniform copying of terrain unevenness. The invention is characterized by the proper use of pneumatic springs (1), installed slant (2), through specific fixing brackets (3) and (4) respectively, to the heavyweight chassis (5) and to the lightweight one (6), and such springs (1) own a technical feature that, when pneumatically driven, they apply some force between the chassis (5) and (6), which they are interconnected to, and transfer the weight of the heavyweight chassis (6) to the lightweight one (5) by reaction, equalizing the weight between them both and the machine weight is transferred to the wheels. Such springs (1) can work independently, interconnected, as a closed system or as an active system.
