Abstract
Matériel permettant de répartir uniformément une quantité de produit pulvérulent ou granulaire avec dosage pondéral continu; régulation et contrôle. Il comprend un châssis 1 mobile portant un tapis doseur bibande 2 alimenté par un silo de stockage 3, de nourrie 4, de vis d'Archimède 5, de trémies tampon. Une goulotte de diffusion 7 répartit ou concentre le produit vers un dispositif de sous-solage. Deux dynamos tachymétriques et un capteur à jauges de contrainte délivrent des tensions nécessaires à un ensemble d'asservissement électronique assurant les fonctions de calcul et de régulation pour obtenir un débit proportionnel à la translation et tenant compte des écarts de masse volumique peut être utilisée dans les travaux publics pour la L'invention peut être utilisée dans les travaux publics pour la répartition de liant hydraulique dans le cas de traitements des sols en place ou en agriculture pour l'amendement des sols.
