Description

方孔钻机
技术领域
本发明涉及一种钻机，特别是一种地下混凝土灌注桩造孔用的方孔钻机。
背景技术
目前，混凝土灌注桩用的钻机都是钻成一圆孔。
发明内容
本发明弥补了以上缺点，提供了一种方孔钻机。
本发明是通过如下技术方案实现的：
一种方孔钻机，钻杆下端设有电机，电机下端固定于连接臂中间，电机轴C下端固定有齿轮C，齿轮C前后两边分别啮合齿轮A和齿轮B，齿轮A中间设有转轴A，转轴A上端固定于连接臂前端，齿轮B中间设有转轴B，转轴B上端固定于连接臂后端，齿轮A上离转轴A一定距离设有销C，齿轮B上离转轴B一定距离设有销D，销C通过臂杆B铰接销B，销D通过臂杆A铰接销A，销A下端固定于拐臂A的左端，销B下端固定于拐臂B的左端，拐臂A、拐臂B下部分别设有多个刀头；连接臂前后两端分别固定轴杆A和轴杆B，杆A上端通过轴套套接于轴杆A左端，杆A下端固定于拐臂B左端；杆B上端通过轴套套接于轴杆A右端，杆B下端固定于拐臂B右端；杆C上端通过轴套套接于轴杆B左端，杆C下端固定于拐臂A左端；杆D上端通过轴套套接于轴杆B右端，杆D下端固定于拐臂A右端。
本发明具有以下有益效果：
本发明可钻挖成方孔。
附图说明
下面结合附图对本发明作进一步的说明；
图1为本发明的结构示意图；
图2为拐臂、齿轮及连接的底视图；
图3为A—A视图；
图4为B—B视图；
图中：1、钻杆，2、电机，3、轴套，4、轴杆A，5、连接臂，6、转轴A，7、齿轮A，8、臂杆A，9、臂杆B，10、销A，11、销B，12、杆A，13、杆B，14、销C，15、拐臂A，16、拐臂B，17、刀头，18、杆C，19、杆D，20、齿轮C，21、轴C，22、转轴B，23、齿轮B，24、销D，25、轴杆B。
具体实施方式
附图为本发明的一种具体实施例，该实施例钻杆1下端设有电机2，电机下端固定于连接臂5，电机轴C21下端固定有齿轮C20，齿轮C前后两边分别啮合齿轮A7和齿轮B23，齿轮A中间设有转轴A6，转轴A上端固定于连接臂前端，齿轮B23中间设有转轴B22，转轴B上端固定于连接臂后端，齿轮A上离转轴A一定距离设有销C14，齿轮B上离转轴B一定距离设有销D24，销C通过臂杆B9铰接销B11，销D通过臂杆A8铰接销A10，销A下端固定于拐臂A15的左端，销B下端固定于拐臂B16的右端，拐臂A、拐臂B下部分别设有多个刀头。
连接臂前后两端分别固定轴杆A4和轴杆B25，杆A12上端通过轴套套接于轴杆A左端，杆A下端固定于拐臂B左端；杆B13上端通过轴套套接于轴杆A右端，杆B下端固定于拐臂B右端；杆C18上端通过轴套套接于轴杆B左端，杆C下端固定于拐臂A左端；杆D19上端通过轴套套接于轴杆B右端，杆D下端固定于拐臂A右端。
本发明工作时，电机驱动齿轮C旋转，齿轮C带动齿轮A、齿轮B旋转，齿轮A旋转时通过臂杆B推拉拐臂B，齿轮B旋转时通过臂杆A推拉拐臂A，如此，拐臂A和拐臂B便相对往复运动起来，刀头在运动中切土成孔，成孔泥浆由反循环置换。
