Bulldozing shovel blade board cutting edge protection device
The invention discloses a bulldozer blade plate cutting edge protection device which comprises a cutting edge protection mechanism located between a bulldozer blade and a blade plate, connecting beams are symmetrically and fixedly connected to the outer side of the bulldozer blade, lifting hydraulic oil cylinders are hinged to the outer sides of the connecting beams, the blade plate is arranged at the bottom of the bulldozer blade, and the cutting edge protection mechanism comprises two rotating shafts. And connecting rods are fixedly connected to the exteriors of the two rotating shafts, an arc-shaped protective outer lining is fixedly connected between the two connecting rods, an arc-shaped protective inner lining plate is slidably connected to the interior of the protective outer lining, and connecting mechanisms are arranged on the exteriors of the two rotating shafts. The arc-shaped protective outer lining and the arc-shaped protective inner lining plate can rotate to the bottom of the scraper knife plate or rotate to the outer side of the dozer blade by operating the operating rod in the cab of the bulldozer, and the arc-shaped protective outer lining and the arc-shaped protective inner lining plate located at the bottom of the scraper knife plate can replace the scraper knife plate to make contact with the ground. And the scraper knife plate is protected, and meanwhile, the protection mechanism does not need to be disassembled manually.
本发明公开了一种推土铲铲刀板刃口防护装置，包括位于推土铲和铲刀板之间的刃口防护机构，推土铲的外侧对称固定连接有连接梁，连接梁的外侧铰接有提升液压油缸，铲刀板设置在推土铲的底部，刃口防护机构包括两个转动轴，两个转动轴的外部均固定连接有连接杆，两个连接杆之间固定连接有弧形防护外衬套，防护外衬套的内部滑动连接有弧形防护内衬板，两个转动轴的外部有连接机构。本发明通过操作推土机驾驶室内部的操纵杆即可使得弧形防护外衬套和弧形防护内衬板转动至铲刀板的底部或转动至推土铲的外侧，而位于铲刀板底部的弧形防护外衬套和弧形防护内衬板能够代替铲刀板与地面接触，即对铲刀板进行防护的同时无需进行人工进行防护机构的拆卸。
