"Electronic-mechanical unblocking device and unblocking of fertilizer application routes". the present utility model patent relates to an electronic mechanical mechanical unblocking and unblocking of fertilizer application pathways (1) which was developed to act, preferably, in the prevention of clogging and obstruction and in the unblocking / unblocking of the dispersion pathways of the fertilizer through vibratory force applied directly to the structure and by gravity, detaching material from the walls of the application tube and dismantling formed calculations, which is characterized by being composed of two modules, one electronic module (2) and the other mechanical (3) both shielded, where the first acts in the activation and disconnection of the second, as well as allows the visualization of the status of its supply and its command to the mechanical module, the mechanical module (3) being composed of a motor and counterweights, which when activated, they produce vibration, and both modules are interconnected by double-bipolar pp cable； the attachment of the vibration module (8) is made to the fertilizer spreading structure by means of metal clamps (9) and its electronic module (2) is attached to the planter structure by means of metal or plastic clamps (9), finally , one of the extremities of the vibration module (8) was designed for coupling of an accordion tubular rubber duct that has the purpose of partially dampening the mechanical energy of the vibration, so as not to transfer the generated force in its entirety, reducing the friction and wear of parts.“dispositivo eletrônico-mecânico desobstrutor e desentupidor de vias de aplicação de adubos”. a presente patente de modelo de utilidade diz respeito a dispositivo eletrônico-mecânico desobstrutor e desentupidor de vias de aplicação de adubos (1) o qual foi desenvolvido para atuar, preferencialmente, na prevenção de entupimentos e obstruções e na desobstrução/desentupimento das vias de dispersão do adubo atr
