The height suitable for loading work can be set freely.

  Also, a gas compression urging force that urges the rear side of the swing receiving frame with a gentle biasing force via a gas compressing force so that the entire material conveying conveyor placed on the swing receiving frame is always kept in a substantially horizontal state. Since the equipment is installed, if the material transport conveyor is placed on the swing receiving frame, the entire conveyor always maintains a substantially horizontal state even if no person supports the rear side of the swing receiving frame. In addition, if necessary, it can be adjusted to a required swing height position by a simple operation of pushing down the rear side of the swing receiving frame downward. Therefore, for example, even if it is a single work, the conveyor can be adjusted so as to have a required inclination, so that the man-hour reduction of the asphalt raw material supply work can be realized.

  The longitudinal movement support fixing mechanism includes a linear lateral movement guide member provided on the swing receiving frame, a rolling member attached to the machine frame of the conveyor and linearly laterally guided by the guide member and slidably engaged. And a fixing means for coupling and fixing at the engagement position of the conveyor frame and the swing receiving frame, the rolling member attached to the conveyor frame can freely slide along the guide member. Therefore, the front and rear positions of the conveyor itself can be freely changed along the guide member, and when the conveyor reaches a required front and rear position, the conveyor and the swing receiving frame are connected to each other via fixing means. Can be connected and fixed. Therefore, for example, the front and rear positions of the conveyor can be easily adjusted so that one end (raw material supply side) of the raw material conveyor is placed on the truck bed, and the truck can be pulled while towing. A mechanism capable of storing the conveyor can be realized so as not to obstruct the vehicle.

  In addition, since the stopper frame that defines the retreat position of the conveyor frame relative to the swing receiving frame is attached to the conveyor machine frame, for example, during a raw material supply operation or an asphalt raw material supply device transfer Even if the fixing means is damaged, the stopper member abuts on the upper end side of the swing receiving frame and restricts its downward movement or rearward movement. And safety during transportation can be improved.

Can be fixed. As described above, since it is possible to easily adjust the inclination angle and the front and rear position of the conveyor 16 for conveying the raw material, even after the conveyor 16 is disposed, for example, the loading condition of asphalt raw material on the truck bed The conveyor 16 can be readjusted as needed during the operation without feeling the complexity. In addition, since the stopper frame 38 is provided on the conveyor frame 30, for example, the rear side of the swing receiving frame 22 swings downward with the fixing means 34 disengaged, and the conveyor 16 slides down. Since the stopper member 38 and the entire end side surface of the swing receiving frame 22 come into contact with each other to prevent the conveyor 16 from descending, safety is improved. Further, after the work is completed, the conveyor 16 can be easily stored and fixed by the reverse procedure described above.

As described above, according to the asphalt raw material supply apparatus of the present invention, the asphalt raw material loaded on the truck bed or the like can be easily and safely transferred to the asphalt regenerator even when the asphalt regenerated vehicle is connected to the truck or the like. An asphalt raw material supply device that can be supplied can be provided.
