Abstract

Appareil de contrôle et de régulation du débit de décharge d'une matière d'un véhicule en mouvement par circuit à réac tion et à boucle fermée. Il comporte un dispositif de détection comprenant une plaque inclinée 46 qui produit un signal correspondant au débit réel d'écoulement de la matière. Ce signal est utilisé, avec un signal indiquant la vitesse du véhicule par rapport au sol, pour corriger la vitesse d'un transporteur 22 qui décharge la matière de fluide d'une trémie 16 dans une chambre 20 dans laquelle la plaque inclinée 46 est placée. Cette matière tombe ensuite sur un distributeur 24 qui la répand sur le sol. Domaine d'application : sablage et salage des chaussées etc.Apparatus for controlling and regulating the discharge rate of material from a moving vehicle by closed loop reaction circuit. It comprises a detection device comprising an inclined plate 46 which produces a signal corresponding to the actual flow rate of the material. This signal is used, along with a signal indicating the speed of the vehicle relative to the ground, to correct the speed of a conveyor 22 which discharges fluid material from a hopper 16 into a chamber 20 in which the inclined plate 46 is placed. . This material then falls on a distributor 24 which spreads it on the ground. Field of application: sanding and salting of pavements etc.
