The invention relates to an icebreaking mechanism for an icebreaker, and discloses an icebreaking mechanism which is used for repeatedly knocking an ice surface through cooperation of a crank and icebreaking nails and can be matched with a connecting block to enable the plurality of icebreaking nails to form an arc-shaped shovel surface contour so as to outwards turn over ice cubes, and the icebreaking mechanism is characterized in that a rotating shaft penetrates through one end of a connecting seat; a driving bevel gear is arranged on the rotating shaft, two guide blocks are arranged at the other end of the connecting base and obliquely arranged on the two sides of the connecting base, mounting holes are formed in the guide blocks, one ends of the two fixing frames are arranged on the two sides of the connecting base respectively, the two fixing frames are not parallel, and an included angle exists between extension lines of the two fixing frames. The included angle is an acute angle. Four fixing bases are arranged on the fixing frames at equal intervals, the longitudinal section of each fixing base is in an L shape, the fixing bases on the two fixing frames are opposite, the multiple connecting columns are arranged at the bottoms of the fixing frames at equal intervals, and the transmission shafts are arranged at the ends of the connecting columns and penetrate through the connecting columns.

    本发明一种破冰船用破冰机构公开了一种通过曲柄和破冰钉相配合对冰面进行反复敲击,同时能够配合连接块使得多个破冰钉形成弧形铲面轮廓,对冰块进行外掀翻转的破冰机构,其特征在于转轴穿过连接座的一端,驱动锥齿轮置于转轴上,连接座的另一端上置有两个导向块,两个导向块倾斜置于连接座的两侧,导向块上开有安装孔,两个固定架的一端分别置于连接座的两侧,两个所述固定架不平行,两个所述固定架的延长线之间存在夹角,且夹角为锐角,四个固定座等距置于固定架上,固定座的纵截面为L形,两个固定架上的固定座相对,多个连接柱等距置于固定架的底部,传动轴置于连接柱的端部上,且贯穿连接柱。
