9. The use method of the cutting device for road and bridge expansion joint construction as claimed in claim 8, comprising the steps of:
a. the motor (4) works to drive the driving disc (401) to rotate, and through the sliding fit action of the guide column (402) and the guide frame (501), thereby utilizing the guide post (402) fixed at the eccentric position of the bottom end of the driving disk (401) to drive the guide frame (501) to longitudinally slide in a reciprocating way, the connecting rod (502) fixed at the rear side of the guide frame (501) pushes the piston disk (502a) to longitudinally slide in a reciprocating way, during the backward movement process of the piston disk (502a), the piston disc (502a) is used as a suction power source to suck the water in the water tank (6) into the transfer tank (3) along the communicating pipe (301), and in the process that the piston disc (502a) moves towards the front side, water in the transfer tank (3) is sprayed out to the bottom side of the cutter (701) along a spray head (303) at the bottom end of the discharge pipe (302) by using a piston disc (502a), so that the temperature reduction of the cutter (701) and the water spraying dust reduction at the position of the expansion joint are realized;
b. in the process that the guide frame (501) slides back and forth in a reciprocating manner under the driving of the guide column (402), a support arm (503) hinged to the outer side of the guide frame (501) synchronously swings, the sliding fit action of a guide groove (503a) and a guide shaft (201) is utilized to keep the outer end part of the support arm (503) in a front and back swinging state, a brush head (505) at the bottom end of a cleaning rod (504) at the end part of the support arm (503) swings back and forth, and the cutting position of an expansion joint is cleaned in advance by the brush head (505);
c. the output end of the motor (4) drives the transmission shaft (204) to synchronously rotate through the transmission belt (206) in the rotating process, the gear (205) at the bottom end of the transmission shaft (204) drives the gear ring (702) at the outer end part of the cutter (701) to rotate, and then the cutter (701) at the outer side of the cutting shaft (7) is driven to keep a rotating state, so that the cutter (701) extending out of the frame (1) downwards cuts the position of the bridge expansion joint, and the cutter (701), the spray head (303) and the brush head (505) are ensured to be synchronously opened and stopped.
