Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge construction, in particular to a ground slot cutting device for road and bridge construction. Background Technique

[0002] Although the concrete slot cutting machine is a small tool with a simple structure, it plays a huge role in the construction of cement roads. Slot cutting is also an essential link in the construction, directly affecting the strength and service life of the road surface. Its working principle is to complete the slot cutting operation by driving a diamond saw blade with power. When the existing ground slot cutting device for road and bridge construction cuts the ground of the road and bridge, debris is easy to fly randomly and relatively loud noise is easily generated. For example, in the patent authorization announcement number CN 109371790 B, although the slot cutting quality can be improved and the service life can be extended, the slot cutting is open during operation, so sealed slot cutting cannot be achieved, and the problems of random flying of debris and generation of relatively loud noise cannot be solved. Content of the Utility Model

[0006] Furthermore, the slitting assembly includes two support foot plates fixed to the lower surface of the vertically adjustable platform. A rotating shaft is fixed between the lower ends of the two support foot plates through a bearing. A cutting blade is fixed in the middle on the outer side of the rotating shaft. An arc-shaped protective plate is arranged between the support foot plates and is located above the cutting blade. When the rotating shaft rotates, it can drive the cutting blade to rotate. By rotating the cutting blade, a slit can be made in the road surface. During slitting, the protective plate prevents debris from flying around randomly.

[0007] Furthermore, the cutting driving member includes a motor fixed to the lower surface of the vertically adjustable platform. Pulley wheels are fixed to the end of the output shaft of the motor and one end of the rotating shaft respectively. The two pulley wheels are driven by a transmission belt. By running the motor, the pulley wheels can be driven to rotate. Through the transmission of the pulley wheels and the transmission belt, the rotating shaft can be driven to rotate.

[0008] Furthermore, the dust removal assembly includes a dust suction head arranged at the lower side of one end inside the support frame, and a dust collector is fixed to one side of the support frame.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: By running the motor, the pulley wheels can be driven to rotate. Through the transmission of the pulley wheels and the transmission belt, the rotating shaft can be driven to rotate. When the rotating shaft rotates, it can drive the cutting blade to rotate. By rotating the cutting blade, a slit can be made in the road surface. By extending and contracting the electric telescopic column, the vertically adjustable platform can be driven to move up and down.
