Title:
LOAD DISCHARGING MECHANISM FOR DUMP TRUCK
Document Type and Number:
Japanese Patent JPH1128961
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To discharge a load in two directions by holding an upper part, of a discharging mechanism freely rotationally in the opening in the rear part, of a deck and performing selection between tight adhesion of the discharging mechanism, by which a load can be moved to the side face of a vehicle body, to the rear part, opening of the deck and release of the discharging device from the rear part opening. SOLUTION: Earth and sand or the like are let flow into a semicylindrical space formed of a cover body 44 via a space S. When oil pressure is transmitted to a hydraulic motor 58, an output shaft 59 is rotated by means of the hydraulic motor 58. The rotation of the output shaft 59 is transmitted to a small gear 60, a large gear 62, and a screw shaft 61 in this order, and consequently, a screw 64 is rotated inside a discharging mechanism 17. As the screw 64 is rotated in the internal space of the cover body 44, the earth and sand flowing into the inside of the cover body 44 via the space S are pushed sideward. For discharging the earth and sand from the back part, in the similar way to an ordinary dump truck, a shielding plate 34 is brought into tight contact with the front face of an intake frame 41 and the space S is closed.
