Forestry work vehicle

Abstract

Abstract THE BASIC WORK VEHICLE COMPRISES A CHEMICAL SPRAYER CARRIED BY A ROUGH TERRAIN FOUR-WHEEL DRIVE CHASSIS, ARTICULATED FOR STEERING. THE SPRAYER IS CARRIED BY THE REAR-HALF OF THE ARTICULATED CHASSIS, IS DIRECTED UPWARDLY AND REARWARDLY, AND HAS THREE JET OPENINGS, EACH WITH ITS OWN MISTPRODUCING SPRAY HEAD, TO SPRAY A WIDE SWATH WITH SATISFACTORY UNIFORMITY. THE BLOWER IS DRIVEN BY A HYDRAULIC MOTOR WHICH MAKES IT EASILY SUPPLIED WITH POWER FROM THE FORWARD HALF OF THE VEHICLE ON WHICH THE ENGINE AND PUMPS ARE MOUNTED. THE HYDRAULIC MOTOR IS OF THE POSITIVE DISPLACEMENT TYPE AND HAS A BY-PASS PROVIDED WITH A PRESSURE RELIEF VALVE WHICH PREVENTS DAMAGE WHEN THE HYDRAULIC FLUID IS SHUT OFF BY A MANUAL CONTROL VALVE. THE VEHICLE CARRIES A HYDRAULICALLY RAISEBLE V SHAPED PLOW AT ITS FRONT END FOR SHEARING OR BENDING ASIDE LIGHT UNDERGROWTH AND CAMMING FRAME BARS OVERHEAD FOR FACILITATING PASSAGE UNDER LOW LIMBS OF TREES. A TRAILER HITCH IS PROVIDED AND A LARGE CHEMICAL TANK IS SHAPED TO GIVE ACCESS TO THE HITCH UNDER IT. ATTACHMENTS FOR THE HITCH INCLUDE A FIRE LANE PLOW AND AT LEAST ONE PLANTER FOR PLANTING TREE SEEDS OR SEEDLINGS. BECAUSE OF THE ARTICULATION, THE VEHICLE WITH TRAILER CAN "SNAKE" A WINDING COURSE AMONG TREES, WITH THE FRONT WHEELS, REAR WHEELS AND TRAILER ALL FLOWING THE PATH CLEAR BY THE V SHAPED PLOW AT THE FRONT.
