Bulldozing device with width adjusting function for bulldozer
The invention discloses a bulldozing device with a width adjusting function for a bulldozer, and belongs to the technical field of bulldozer auxiliary devices. The device comprises a scraper knife mounting seat, a press rod and a movable insertion rod are movably inserted into the front end and the rear end of the part, connected with an electric telescopic rod, of the outer wall of the top of a lifting plate, and limiting plates are connected to the outer walls of the parts, located at the bottom of the lifting plate, of the press rod and the movable insertion rod in a sleeving mode. According to the device, when two movable scraper knives slide, the extending width of an auxiliary plate can be changed; at the moment, a movable push broach is exposed, and then the electric telescopic rodis started and drives the lifting plate and the press rod to descend; the press rod descends to drive an ejection block to eject the movable push broach towards the rear side, so that the movable pushbroach stretch out of the auxiliary plate; the movable push broach ejects the movable insertion rod upwards in the initial state to stretch a spring; and when the movable push broach continues to moves backwards to enable a positioning groove to be located in the bottom of the movable insertion rod, the spring drives the movable insertion rod to be inserted into the positioning groove to fix themovable push broach.
本发明公开了推土机辅助设备技术领域的一种推土机用具有宽度调节功能的推土器，包括铲刀安装座，所述升降板顶部外壁与电动伸缩杆连接部分的前后两端分别活动插接有压杆和活动插杆，所述压杆和活动插杆位于升降板底部部分的外壁均套接有限位板，在两组活动铲刀滑动时，辅助板伸出的宽度会发生变化，此时活动推刀露出，然后启动电动伸缩杆，电动伸缩杆带动升降板和压杆下降，压杆下降带动顶块将活动推刀向后侧顶，使活动推刀伸出辅助板，且活动推刀在初始状态时将活动插杆向上顶，将弹簧拉伸，当活动活动推刀继续向后移动使定位槽位于活动插杆底部时，弹簧将带动活动插杆插入定位槽中将活动推刀固定。
