<p>#CMT# #/CMT# The conduit (8) has an end emerging in front of axis of a front axle of a vehicle and another end rejoining a tank. The former end is extended by a nozzle (10). The nozzle includes a fixed part (10') and a removable part (10'') connected with each other by a male or female type rapid fastening or unfastening unit i.e. projecting tenon (20') associated to a locking unit. The fixed part of the nozzle has a U shaped support (15) mounted at the former end of the conduit and including lateral branches receiving the fastening or unfastening unit in respective rear parts. #CMT#USE : #/CMT# Suction conduit for use in a road maintenance vehicle i.e. urban sweeper, for urban road work, to collect solid or liquid rubbish, on a highway zone e.g. channel or gutter, located on sides of the vehicle. #CMT#ADVANTAGE : #/CMT# The end of the conduit is extended by the nozzle in the removable part with the fastening or unfastening unit to permit modulation between different suction modes. The other end of the conduit emerges in front of the axis of the front axle of the vehicle, so as to provide perfect visibility to an operator in a cabin. The male or female type rapid fastening or unfastening unit i.e. projecting tenon, is associated to the locking unit and closely positioned in front of the suction conduit, so that direct soil suction or offset suction is implemented based on the need or ground constraints, without the need of immobilizing the vehicle or depositing structural elements to realize modification, thus reducing a space between the conduit and an active zone of a debris sampling unit in front of the vehicle. The space is minimized to reduce the risk of loss of rubbish on the sides. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a free end part of a suction conduit with a nozzle and rapid fastening unit in offset suction configuration. 8 : Suction conduit 10 : Nozzle 10' : Fixed part 10'' : Removable part 15 : U shaped support 20' : Projecting tenon.</p> |
