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。

Abstract: A lubricant reservoir is positioned in each of the three arms of a three cone rotary rock bit to provide lubricant to the bearings located between the cone cutters and the bearing shafts upon which they rotate. A seal is positioned between the cone cutters and the bearing shafts to retain lubricant in the bearing area and to prevent borehole fluids and debris from entering the bearing area. A flexible diaphragm positioned in the lubricant reservoir divides the reservoir into a lubricant portion and a pressure equalizing portion. A vent passage extends from the pressure equalizing portion of the lubricant reservoir to an area on the exterior surface of the bit wherein the borehole fluid pressure on the bit is substantially the same as the borehole fluid pressure on the seal.
Abstract translation: 润滑剂储存器定位在三锥形旋转岩石钻头的三个臂中的每一个中，以向位于锥形切割器和它们旋转的轴承轴之间的轴承提供润滑剂。 密封件位于锥形切割器和轴承轴之间，以将润滑剂保持在轴承区域中并防止钻孔流体和碎屑进入轴承区域。 定位在润滑剂储存器中的柔性隔膜将储存器分成润滑剂部分和均压部分。 排气通道从润滑剂储存器的均压部分延伸到钻头的外表面上的区域，其中钻头上的钻孔流体压力与密封件上的钻孔流体压力基本相同。

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。
