An arrangement for automatic protection against operational failures in an agricultural implement for mixture and/or distribution of a solid product having variable granulometry, said arrangement comprising:
- a chassis or a structural base constructed with beams or steel tubes, the chassis or the structural base operatively associated to a tractor unit;
- at least one helical pitch thread or auger, with bearing shafts in walls or a bottom of a reservoir or a load box, and a terminal element projecting from the at least one helical pitch thread or auger to the walls or the bottom of the reservoir or the load box, wherein the terminal element is coupled to a motor source;
- and
- a sensor that interoperates with a computer through a backplane or a wireless transmission network to activate a volumetric displacement control valve when a pressure limit is exceeded;
- wherein the computer sends an analogic or digital signal for reversing a swivel direction and/or reducing rotation of the at least one helical pitch thread or auger, in an independent and/or synchronized manner, causing a new round in a circuit in a traction system of the at least one helical pitch thread or auger, thereby providing an additional force for disaggregating the solid product that has caused locking of the rotation of the at least one helical pitch thread or auger.
