Novel scraper knife supporting structure for bulldozer
The invention discloses a novel scraper knife supporting structure for a bulldozer, and belongs to the technical field of bulldozers. The novel scraper knife supporting structure comprises a knife head, a support comprises a connecting cap, a spherical structure is movably inserted into the connecting cap, the spherical structure is connected with a mounting base in a spherical hinge mode, and a bearing pipe is welded to the right end of the spherical structure. A screw pipe is welded to the right end of the bearing pipe. The left end of a movable rod is movably sleeved with a sleeve rod. Themiddle of the outer wall of the screw pipe is fixedly sleeved with an annular base. Only two sets of weld joints are adopted, the number of the weld joints is small, the cost is low, the structure issimple, meanwhile, the support provided with no steering hole, a stress concentration area does not exist, and the bending resistance and the bearing capacity are high. Meanwhile, the length of the support is adjusted through a servo motor, a gear is driven by the servo motor, the screw pipe is driven to rotate through cooperation of the gear and teeth, adjustment of the length of the support is achieved, manpower is not needed, the manual adjusting strength is reduced, use is convenient, and the rotating efficiency is high.
本发明公开了推土机技术领域的一种推土机用新型铲刀支撑结构，包括刀头，所述支撑包括连接帽，所述连接帽上活动插接有球形结构，所述球形结构与安装座以球铰接的形式连接，所述球形结构右端焊接有承重管，所述承重管右端焊接有螺管，所述活动杆左端活动套接有套杆，所述螺管外壁中部固定套接有环形座，本发明只采用两组焊缝，焊缝少，成本低，结构简单，同时该支撑不带有转向孔，不存在应力集中区，抗弯及承重能力强，同时该支撑的长度调节通过伺服电机，伺服电机驱动齿轮，通过齿轮和齿牙的配合，从而带动螺管进行转动，实现支撑的长度的调节，不需要人工，降低人工调节强度，使用方便，转动效率高。
