<p>A striking sheet of an icebreaking rod can be hinged on supporting seats evenly distributed on an outer periphery of the icebreaking rod, and comprises an S-shaped smooth curve bended connecting arm (1), which may be a curved-surface plate-shaped arm or rod-shaped crank arm. A removable striking blade device is arranged on the head portion of the S-shaped smooth curve bended connecting arm, and the tail end of the connecting arm is connected with a shaft sleeve (2) and a damping limiting device (5) matched with the shaft sleeve. The striking sheet of an icebreaking rod can reduce the impact force of an icebreaking blade on a hinged shaft and the supporting seats, disperse the impact force borne by the connecting arm and prolong service life. The icebreaking blade is removable, so that using cost is reduced, and maintenance cost is reduced.</p> |
