Title (EN) MOBILE EQUIPMENT FOR CLEANING SAND AREAS
(FR) MATERIEL MOBILE POUR LE NETTOYAGE DE TERRAINS DE SABLE
Abstract:
(EN) The mobile equipment includes devices for stirring the sand up in depth and picking up particles thereof. The devices include a bladed rotor (3) and a vibrating screen (7) located behind the rotor (3) and to the rear with respect to the direction of movement (f1) of the equipment for catching refuse and letting through the sand. A curved grid (5, 6) lies around the rotor over at least an upper rear quarter thereof so that it lets through sand (S) and small refuse (P) while deflecting large refuse (G) forwards. The devices also include a substantially flat grid (11) located forward of the rotor (3) and to the front with respect to the direction of movement (f1) of the equipment, and interleaved with the bladed (4) rotor (3) for collecting the large refuse (G) deflected by the curved grid (5, 6) and depositing it on a receptacle (12). A device is provided for spraying the sand with a liquid disinfectant solution, and the equipment can be used for cleaning and disinfecting sandy beaches.
(FR) Le matériel mobile comprend des moyens remuant le sable en profondeur et le ramassant en particules. Ces moyens comprennent un rotor muni d'ailettes et, à l'arrière du rotor (3) et en aval par rapport au sens (f1) de déplacement du matériel, un tamis vibrant (7) retenant les déchets et laissant passer le sable, associé à une grille en arceaux (5, 6) entourant le rotor au moins sur un quart supérieur arrière laissant passer le sable (S) et les petits déchets (P), et défléchissant les gros déchets (G) vers l'avant. Ces moyens comprennent aussi, à l'avant du rotor (3) et en amont par rapport au sens (f1) de déplacement du matériel, une grille (11) sensiblement plane faisant peigne avec le rotor (3) à ailettes (4), reprenant les gros déchets (G) défléchis par la grille en arceaux (5, 6) et les déposant sur un réceptacle (12). Des moyens de pulvérisation d'une solution liquide désinfectante sont prévus pour asperger le sable; le matériel peut être utilisé pour le nettoyage et la désinfection des plages de sable.
