Abstract: An earth boring method using a multiplicity of motors provides a wide range of rotational torques and speeds for optimum drilling performance. One of the multiplicity of motors is supplied with power to drive the rotary drill string at high speed for drilling a pilot hole with the other motors disengaged from the bull gear. When enlarging the pilot hole into a large diameter hole two or more of the motors are supplied with power and engaged with the bull gear.
Abstract translation: 使用多个电动机的大地钻孔方法提供了广泛的旋转转矩和速度以获得最佳的钻井性能。 多个电动机之一被提供动力以高速驱动旋转钻柱，用于钻出导向孔，其他电动机与大齿轮脱离。 当将导向孔扩大到大直径孔时，两个或多个电动机被供电并与大齿轮啮合。

Abstract: A drill pipe positioner that will lift, position and release a section of drill pipe in proper relation to the drill head and other elements of an earth boring machine and by reversing the action will attach to a section of drill pipe, lift and release it for removal and stacking. A first arm pivots on the support columns and a second arm unit pivots on the first arm. Grippers are attached to the second arm unit for gripping and holding a section of drill pipe.
Abstract translation: 钻杆定位器将提升，定位和释放与钻头和钻孔机的其他元件适当关系的一段钻杆，并通过反向动作将附接到钻杆的一部分，提升并释放 搬运和堆放。 第一臂在支撑柱上枢转，第二臂单元在第一臂上枢转。 夹持器附接到第二臂单元以夹持并保持一段钻杆。

Abstract: An apparatus for supporting the earth formations above an earth boring machine. The lower portion of a reaction post is connected to the support columns of the earth boring machine and the upper portion of the reaction post contacts the earth formations. The upper and lower portions are connected by a threaded connection and a spring maintains a constant rotary force on the threaded connection thereby supplying a constant axial force through the reaction post to the earth formations.
Abstract translation: 用于支撑地面钻孔机上方的地层的装置。 反应柱的下部连接到镗孔机的支撑柱，并且反应柱的上部接触地层。 上部和下部通过螺纹连接连接，并且弹簧在螺纹连接上保持恒定的旋转力，从而通过反应柱向地层提供恒定的轴向力。

Abstract: A hopper for deverting residue and cuttings from the boring machine when drilling upward. The hopper includes a main cylindrical body open at both ends. Two symmetrical deflection elements are pivotably connected to the main body of the hopper. A plate opposite the pins provides support for the deflection elements and allows them to slide to provide adjustment of the size of the central opening.
Abstract translation: 用于在向上钻孔时从镗床中除渣和切屑的料斗。 料斗包括在两端敞开的主圆筒体。 两个对称的偏转元件可枢转地连接到料斗的主体。 与销相对的板为偏转元件提供支撑，并允许它们滑动以提供中央开口的尺寸的调整。
