Claims

[Claims for Utility Model Registration] 1. A rotary excavator 7 is vertically movably connected to the front of the traveling machine body B via an elevating mechanism 8, and the excavator 7 is pivotally supported at the lower part of an excavation transmission case 19. In the road making machine, the cover body 23 is formed of an excavation shaft 21, a large number of excavation claws 22 installed on the outer periphery of the excavation shaft 21, and a cover body 23 that covers the upper part of the excavation claws 22.
The center cover 2 covers the inner digging claw group 22a1.
3a, and a side cover 23b that covers the outer digging claw group 22b on both sides thereof.
By moving b relative to the center cover 23a,
A road making machine characterized in that the upper part of the outer digging claw group 22b is left uncovered. 2. The rotary excavator 7 is connected to the front of the traveling body B via the lifting mechanism 8 so as to be able to rise and fall freely, and the rotary excavator 7 is connected to the traveling body B via the horizontal swing mechanism 31 between the traveling body B and the rotary excavator 7. On the other hand, this road making machine is characterized in that the rotary excavator 7 swings from side to side.
