Overload protection mechanism for dozer blade
The invention discloses a dozer blade overload protection mechanism which comprises a U-shaped connecting beam, a lifting hydraulic oil cylinder and a dozer blade, auxiliary mechanisms used for assisting the dozer blade in dodging action are symmetrically arranged between the U-shaped connecting beam and the dozer blade, and each auxiliary mechanism comprises two elastic telescopic lugs fixedly connected to the lower portion of the outer portion of the dozer blade. A fixed shaft is fixedly connected between the two telescopic lugs, a gear is fixedly connected to the middle of the fixed shaft, an elastic telescopic rack is arranged above the gear, and the elastic telescopic rack is located on the outer side of the dozer blade; a stabilizing mechanism used for improving the connecting stability of the dozer blade is arranged between the U-shaped connecting beam and the dozer blade and comprises an elastic telescopic rod fixedly connected to the upper portion of the outer portion of the dozer blade, and an inclined telescopic rod hinged to the middle of the U-shaped connecting beam is arranged outside the elastic telescopic rod. By means of the mechanical driving mechanism, the dozer blade can make the avoiding action in time, and the situation that the dozer blade continuously extrudes large hard objects and is damaged is avoided.
本发明公开了一种推土铲过载保护机构，包括U形连接梁、提升液压油缸和推土铲，U形连接梁和推土铲之间对称设置有用于辅助推土铲做出避让动作的辅助机构，辅助机构包括固定连接在推土铲外部下方的两个弹性伸缩耳，两个伸缩耳之间固定连接有固定轴，固定轴的中部固定连接有齿轮，齿轮的上方设置有弹性伸缩齿条，弹性伸缩齿条位于推土铲的外侧；U形连接梁和推土铲之间设置有用于提升推土铲连接稳定性的稳定机构，稳定机构包括固定连接在推土铲外部上方的弹性伸缩杆，弹性伸缩杆的外部设置有铰接在U形连接梁中部的倾斜伸缩杆。本发明通过机械式驱动机构的方式使推土铲能够及时做出避让动作，避免推土铲持续挤压大型硬物而发生损坏。
