Road cutting machine is used for pavement repairing or trench excavation in the sectors of road, municipal engineering, construction, gas and telecommunication. It is much more minimized, energy saving, easy to transport and dynamic compare with cutting machine with electric motor.
It is therefore an object of the present invention to provide a cutting device for cutting asphalt, concrete and the like, which overcomes the drawbacks of the prior art portable and self-propelled cutting devices. It is another object of the present invention to provide a cutting device for cutting asphalt, concrete and the like, which can be easily attached / detached to a front loader, a slip steering gear or the like self-propelled construction vehicle. It is another object of the present invention to provide a cutting apparatus for cutting asphalt, concrete and the like, wherein at least one cutting blade is mounted on the apparatus and is driven to rotate and cut in a counterclockwise direction with respect to the forward cutting direction.
It is another object of the present invention to provide a cutting apparatus for cutting asphalt, concrete and the like, which comprises a diesel engine for winding a circular cutting device. It is another object of the present invention to provide a cutting device for cutting asphalt, concrete and the like, which is mounted on a frame structure.
The method is easy to adjust to compensate for the normal wear of the drive mechanism for transmitting the engine torque to the cutting blade. In one embodiment, the cutting device of the present invention comprises a diesel or petrol engine mounted on a frame structure, which is detachable and connectable to a front loading vehicle, such as a slip guide.
The cutting assembly is powered by the power output and the pulley drive mechanism (also mounted on the frame structure).
The first cutting blade is included in the cutting assembly such that the rotational force rotated by the pulley drive mechanism rotates the cutting blade radially with respect to the advancing direction of the front loader in a direction opposite to the counterclockwise direction. The frame structure includes a mounting portion and a portion for attaching the frame structure to the loader. The mounting portion preferably comprises a board arranged to be attached to the connecting blade of the front loader.
The device also includes a guide frame or a cleat. With the spring lever mechanism, the cleat extends out of the down from the structure for contacting the surface to be cut in order to define and control the cutting depth. It also preferably includes a shroud or fairing around the cutting blade, and one or more nozzles mounted inside the fairing for providing fluid flow directly on the blade when the blade is engaged and cut.
