っている。Generally, an asphalt finisher for paving the roadbed and making roads includes, in order from the front of a traveling vehicle, a hopper for storing asphalt mixture, a feeder for transporting the asphalt mixture in the hopper, and a feeder for transporting the asphalt mixture from the hopper. The structure consists of a screw that spreads the asphalt mixture (paving material) left and right, and a screed that spreads the asphalt mixture spread by the screw. There is a floating type that is attached to the swinging end of a movably provided leveling arm. In this case, the front end of the leveling arm is pivotally supported by the vehicle and extends in the longitudinal direction of the vehicle, and the screed is attached to the rear end, which is the swinging end, in a suspended state. ing. Then, by using the screed's own weight, a certain surface pressure is applied to the asphalt mixture to spread it evenly, or a double-acting cylinder is attached to the screed, and only the pressure in the hydraulic circuit on one side of this double-acting cylinder is changed. The screed is raised slightly, and the asphalt mixture is spread evenly with a surface pressure that is smaller than the surface pressure caused by the screed's own weight.

作が可能な減圧弁１４と同一構成のものとしてもよい。Hereinafter, an embodiment in which the present invention is applied to an asphalt finisher will be described with reference to the drawings. Reference numeral 1 in FIG. 1 is a running vehicle of Asphalt Fini Nya AF, the basic structure of which is well known. This traveling vehicle 1 is composed of a vehicle body 2, wheels 3, a driver's seat 4, and the like. A hopper 5 for storing asphalt mixture (paving material) is provided at the front of a vehicle body 2 of a traveling vehicle 1. The asphalt mixture in this hopper 5 is transferred to the rear of the vehicle body (to the right in Figure 1) by a feeder (path shown) at the bottom of the car body, and then spread evenly to the left and right by a screw (path shown). It is designed to be leveled by a screed 6. The screed 6 is of a floating type and is attached in a suspended state to the swinging end of a leveling arm 7 that is provided on the body of the traveling vehicle l so as to be swingable up and down. The leveling arm 7 has a front end pivotally supported by the vehicle body 2 via a support shaft 8 on both sides of the vehicle body 2, and extends in the longitudinal direction of the vehicle body 2. A screed 6 is installed. Note that the support shaft 8 is
It is operated to move up and down by a pivot cylinder 9. A hydraulic screed cylinder (hydraulic device) 10 is provided between the driver's seat 4 and the rear end of the screed. That is, this screed cylinder 10 consists of a cylinder main body 10a and a rod 10b, and the end of the cylinder main body tOa is rotatably connected to the driver's seat 4, and the end of the rod lOb or the rear end of the leveling arm 7 is rotatably connected to the cylinder. combined. Reference numeral 11 in FIG. 2 indicates a hydraulic circuit connected to the screed cylinder 10, in which 12 is a hydraulic power unit, 13 is a relief valve, and 14 and 15 are pressure reducing valves with relief mechanisms. Among these, the pressure reducing valve 14 is
Remote control is possible. According to the above-mentioned asphalt finnonya AF, the screed cylinder 10 allows the screed 6 to obtain a desired paving pressure via the leveling arm 7, and the screed is finished! ' The pressure of the pressure reducing valve 15 in the hydraulic circuit ll in 10 is set to a constant value, and the pressure of the pressure reducing valve 1 is set to a constant value.
By remotely setting the set pressure in step 4 to an arbitrary value,
The advancing force of the rod 10b of the screed cylinder 10 is changed to adjust the surface pressure of the screed 6 against the paved surface. Thereby, the surface pressure of the screed 6 against the asphalt mixture can be set arbitrarily. Also, mouth] 0
If a greater external force is applied to b, the opening 10b will move back or the set pressure will remain constant. Therefore, by adjusting the set pressure of the screed cylinder 10, the surface pressure of the screed 6 against the asphalt mixture can be set to be greater than or less than the own weight of the screed 6. Thereby, the surface pressure of the screed 6 against the asphalt mixture due to the swinging of the leveling arm 7 can be arbitrarily set so as to obtain the best paving condition. Note that the pressure reducing valve 15 in the hydraulic circuit 11 may have the same configuration as the pressure reducing valve 14 that can be remotely operated.
