The present invention belongs to the field of machines and agricultural implements, more concretely agricultural implements for the mixture and/or distribution of a solid product having variable granulometry, such as, for example, silage, crumbs, clusters, in powder, among others, such as feedstuff and mineral supplements. Moreover, the present invention brings as main advantage, relative to the implements known to the state of the art, the fact that it has a torque limiting means over the movable parts, such as helical pitch threads, augers and/or beater arms, so that there is no overload in the hydraulic system of the implement that is operatively associated to the tractor unit. Further, the invention in question counts on a protection means, with paralyzation and partial reversal and/or rotation reducer, in an independent and/or synchronized form, of the movable parts, in case the hydraulic circuit of the implement detects a pressure that is over the preestablished value, avoiding damages and unscheduled stops of the implement.
ARRANGEMENT INTRODUCED FOR AUTOMATIC PROTECTION AGAINST OPERATIONAL FAILURES IN AN AGRICULTURAL IMPLEMENT FOR MIXTURE AND/OR DISTRIBUTION OF A SOLID PRODUCT, HAVING VARIABLE GRANULOMETRY OF THE MIXER TYPE IMPLEMENT AND/OR DISTRIBUTOR comprising a chassis (01) or a structural base constructed in beams or steel tubes, whereby this chassis or structural base is operatively associated to a tractor unit, such as a wheel tractor, conveyors, or truck (not represented), whereby there is at least one helical pitch thread or auger (04), with bearing shafts in the walls or at the bottom of a reservoir or load box (03), from which there projects a terminal element, such as an hexagonal or splined shaft, coupled to a motor source such as a hydraulic, electrical or pneumatic motor, being characterized by the fact that it comprises a sensing means, such as a pressure or optical or inductive rotation or pressure reading of the circuit, whereby these sensing means (06) interoperate with a computer means through a backplane or a wireless transmission network to activate a volumetric displacement control valve, in case the pressure is exceeded, as well as, the computer means sends an analogic or digital signal for reversing the swivel direction and/or reducing the rotation of the movable parts, in an independent and/or synchronized manner, causing a new round in the circuit in the traction system of these movable parts, whereby in the referred activating there is an additional force that is inherent to the start ramp of the machine or equipment.
