Abstract:
1. A self-propelled bagging machine for storing grain in a sleeve made up of an upper receiving hopper which outlet leads to a grain discharge tunnel over which such folded sleeve fits, said hopper, tunnel and sleeve being mounted on a chassis equipped with running gear and dragging pole, where such hopper outlet comprises a partition wall that is transversally connected to the hopper according to a downward slant plane leading to the discharge tunnel arranged under the vertical projection of the mouth of said hopper, and where such running gear comprises a back single-shaft running gear permanently connected with the wheels, and a smaller front steering running gear; such grain bagging machine being further CHARACTERIZED in that it includes a dual compensated braking device comprising: an adjustable primary hydraulic braking mechanism and an adjustable secondary hydraulic braking mechanism which act simultaneously on the back shaft of the bagging machine, and where a mechanic articulation mounted on the chassis sensitive to pulling variations during the machine operation acts on an inverted operation hydraulic pump for reception and release of braking fluid from and to the secondary braking mechanism circuit for braking compensation.
