Abstract
La présente invention a pour objet un procédé et un dispositif de mesure de la densité d'implantation de plantes sur le sol en vue du réglage du débit d'une machine moisonneuse, au moyen d'un champ d'ultra-sons qui pénètre dans la masse des plantes à moissonner pendant que celles-ci ne sont pas encore coupées, à proximité immédiate des outils moissonneurs, devant cuex-ci, la chute d'intensité dudit champ entre ledit émetteur et ledit récepteur étant converti en un signal de commande assurant ledit réglage du débit précité. Selon l'invention ledit camp d'ultra-sons est constitué par au moins une barrière ultra-sonore discontinue formée d'impulsions ultra-sonores modulées en fréquence, dont le temps de transit et/ou le déphasage entre l'émetteur et le récepteur sont également utilisés pour la production dudit signal de commande. Application dans le domaine de la construction des machines agricoles.
