PURPOSE:To obtain a dump truck having different functions in accordance with the kinds of loaded substances, by providing, to the dump truck, a loading chamber having charging and discharging ports which are made at least in part of flexible or elastic members. CONSTITUTION:A partition member 13 made of a flexible or elastic member such as, for example, a rubber sheet, is fixed to a load charging port 11 by means of a securing member 13. A load which is charged from the charging port 11 is stored into a loading chamber 14, and when the amount of the load is increased, the partition member 12 bulges out as shown by 12', and therefore, the inside volume the loading chamber 14' varies in accordance with the amount of the load. A discharge port 15 which is communicated with the loading chamber 14, is integrally incorporated with the partition member 12 with the use of a flexible or elastic member, and is closed by an opening and closing mechanism composed of two shut-off valves 16, a reverse screw and a control handle 17 for rotating the screw. Further the opening degree of the discharge port 15 may be controlled by the same mechanism. |
