Abstract
Moissonneuses-batteuses dans lesquelles des moyens sont prévus pour alerter le conducteur lorsque les cribles risquent de se colmater. Une moissonneuse-batteuse comprend des moyens de nettoyage du grain, un ventilateur, et un appareil propre à indiquer un colmatage des moyens de nettoyage; cet appareil comprend des palpeurs 52 percevant le courant d'air et délivrant plusieurs premiers signaux, un organe de contrôle 54 qui réagit à la différence entre ces signaux et un signal prédéterminé en délivrant plusieurs seconds signaux, et des moyens avertisseurs 56 qui réagissent à la polarité des seconds signaux. L'organe de contrôle 54 contient un élément à seuil 60 pour délivrer un signal et un détecteur 62 qui répond à chaque premier signal et en en délivrant un second.Combine harvesters in which means are provided to alert the operator when the screens may become clogged. A combine harvester comprises means for cleaning the grain, a fan, and an apparatus suitable for indicating a clogging of the cleaning means; this apparatus comprises probes 52 perceiving the air current and delivering several first signals, a control member 54 which reacts to the difference between these signals and a predetermined signal by delivering several second signals, and warning means 56 which react to the polarity of the second signals. The controller 54 contains a threshold element 60 for providing a signal and a detector 62 which responds to each first signal and by providing a second.
