Rotary excavation square pile hole cleaning drill
The invention belongs to the technical field of engineering machinery, and particularly relates to a rotary excavation square pile hole cleaning drill. The rotary excavation square pile hole cleaning drill comprises a power input connection square head and an installation machine frame plate; an installation plate is welded to the bottom of the power input connection square head; the bottom of the installation plate is connected with an outer ring of a slewing bearing with outer teeth; an inner ring of the slewing bearing with the outer teeth is in screw joint to the middle of the top of the installation machine frame plate through a screw; movable grooves are longitudinally formed in the left side and the right side of the top in the installation machine frame plate; bearings are installed on the inner walls of the movable grooves; the inner walls of the bearings are connected with the outer walls of connection columns; the tops of the connection columns are connected with a transmission gear; and when the power input connection square head conducts slewing motion through power input of a rotary excavation drilling machine, the outer gear ring part of the slewing bearing is driven to rotate, and the inner ring and a rack do not rotate. Accordingly, installation supporting and power transmission of the whole hole cleaning drill are achieved, accordingly, hole cleaning in a building pile is completed through a soil clamping plate, safety is higher, and the hole cleaning efficiency is higher.
本发明公开的属于工程机械技术领域，具体为旋挖方桩清孔钻，包括动力输入连接方头与安装机架板，所述动力输入连接方头底部焊接有安装板，所述安装板底部与带外齿回转支承外圈连接，所述带外齿回转支承内圈通过螺钉螺接在安装机架板顶部中间，所述安装机架板内顶部左右两侧均纵向开设有活动槽，所述活动槽内壁安装有轴承，所述轴承的内壁与连接柱外壁连接，所述连接柱的顶部与传动齿轮连接，当动力输入连接方头经旋挖钻机动力输入作回转运动时，便带动回转支撑外齿圈部分转动，而内圈及机架不发生转动。以此来实现了整个清孔钻的安装支撑和动力传递，从而通过夹土板完成了对建筑桩内的清孔，更加的安全，清孔效率更高。
