Drill barrel structure of rotary drilling rig
The invention provides a drill barrel structure of a rotary drilling rig. A piston, a pressing rod and a lock hook are installed in a drill barrel, a push rod and a rack push rod are installed at thetop of the drill barrel, a power pressing disc makes contact with the rack push rod firstly during soil unloading, and the lock hook is driven to rotate through the rack push rod, a linkage assembly and the pressing rod so as to control a bin door on the drill barrel to be opened and closed; and then the power pressing disc makes contact with the push rod, and the piston is driven to move throughthe push rod so as to push soil in the drill barrel to enable the soil to fall off from the drill barrel. According to the drill barrel structure of the rotary drilling rig, the soil unloading qualityand the soil unloading working efficiency can be effectively improved, and automatic opening and closing of the bin door are achieved; and the rotary drilling rig does not need to unload the soil through shaking, so that noise pollution is greatly reduced, the phenomena of damage to health of constructors and noise disturbing are avoided, meanwhile, auxiliary personnel do not need to be arrangedto knock the drill barrel or open and close the bin door, and personnel waste caused by knocking of the drill barrel or opening and closing of the bin door is avoided.
一种旋挖钻机钻筒结构，钻筒内安装有活塞、压杆和锁钩，钻筒顶部安装有推杆和齿条推杆，卸土时动力压盘先与齿条推杆接触，通过齿条推杆、连动组件、压杆带动锁钩转动从而控制钻筒上的仓门开、闭；然后动力压盘再与推杆接触，通过推杆带动活塞移动，以推动钻筒内的泥土，使泥土从钻筒内掉落。该旋挖钻机钻筒结构可以有效提高卸土质量和卸土的工作效率，并实现仓门的自动开、闭；旋挖钻机无需通过抖动进行卸土，从而极大地降低了噪音污染，避免损害施工人员的健康和发生噪音扰民现象，同时也无需设置辅助人员以敲打钻筒或开、闭仓门，避免由此产生的人员浪费。
