This invention solves these conventional problems and greatly reduces the vibration load acting on the rotary blade from the prime mover, extending the life of the rotary blade by about 40 to 50% and reducing work costs. The purpose is to provide an excellent road cutter device that can operate at high speeds and shorten working time.The main structure of this device is to install a running wheel at the lower rear of the base, and a rotary blade for cutting the road surface at the front side. In the road cutter device, which is equipped with a prime mover that drives the rotary blade on the upper center of the base, the base is made of FRP, a steel plate is laid on the upper center of the base, and a steel plate is placed on the upper center of the base. The prime mover is installed, and the same steel plate and space are installed.
The road cutter device is characterized in that a steel plate of a required thickness is attached to the rear upper surface of the base with the parts separated from each other, and a drive transmission mechanism for the rotary blade is mounted on the steel plate.

This idea uses FRP, which has good vibration absorption properties, as the material for the base, which not only greatly absorbs vibrations, but also places a steel plate under the prime mover.
In addition, by attaching a required steel plate to the upper rear surface at a slight distance from the same steel plate and placing the drive transmission mechanism for the rotary blade on this upper surface, the deflection vibration of the base is suppressed and vibration absorption is made more effective. It is something that In addition, since the steel plate on which the prime mover is placed and the steel plate on which the drive transmission mechanism for the rotary blade is placed are spaced apart, vibration transmission and interference are extremely small, and vibration damping and absorption can be increased. . This has made it possible to extend the life of the rotary blade by about 40 to 50% compared to conventional bases made of steel.

As a result, in the case of the conventional steel base 1, the vibration load acting on the mounting bed 9 of the rotary blade 3 is about 10G when the load is applied, but in this embodiment, it is about 2.1 to 3.3G when the load is applied. This greatly reduced vibration. The lifespan of the diamond rotating blade has been extended by 40 to 50% compared to conventional steel-based blades. The material for the base may be either FRP with reinforcing material such as reinforcing steel or unreinforced FRP.
