PRINCIPAL SUPPORTING STRUCTURE FOR A PORTABLE MACHINE USED, WHEN FULLY EQUIPPED, IN TAKING EARTH CORE SAMPLES DURING EARTH OR SOIL TESTING OPERATIONS

摘要

ABSTRACT OF THE DISCLOSUREA principal supporting structure for a portable machine used, whenfully equipped, in taking earth core samples during earth or soil testing opera-tions, in one embodiment, is essentially an upstanding hydraulic cylindersub-assembly, comprising, a hydraulic cylinder serving as the principalvertical stationary body of this portable machine, a piston rod serving as theprincipal vertical extendable body of this portable machine, an elongated guidemember secured to the exterior of the hydraulic cylinder, a sleeve slidable upand down the hydraulic cylinder, while following the elongated guide member,force transmitting tie rods secured between the extendable end of the piston rodand the sleeve, and a base, preferably removably secured to the bottom of thehydraulic cylinder and having radially extending legs terminating in receivingportions each having a removable earth penetrating stake, and thereby beingready to receive other sub-assemblies to complete the overall portable machine,such as a hydraulic driving power unit sub-assembly mounted on the sleevewhich slides up and down the hydraulic cylinder, comprising, in turn, a drivinghydraulic motor and its attachment accessories to secure and to rotate a hollowcore digging auger, a transverse header box having a sheave mounted at each ofits ends and in turn mounted on the extendable end of the piston rod, and alsohaving a capstan secured to the attachment accessories of the hydraulic motorto receive and to power a rope passing over the sheaves of the transverse headerbox, when the end of the rope is attached, for example, to a calibrated hammerused in preparing a core sample, and the other end of the rope is guided by anoperator to and from the capstan, where the rope is wound around at least onetime, a hydraulic control sub-assembly secured to the elongated guide member onthe hydraulic cylinder at a height for convenient manipulation by an operator,comprising, in turn, a multiple valve sub-assembly to direct hydraulic liquid tothe hydraulic motor for operation in either rotational direction and to directhydraulic liquid to the hydraulic cylinder to extend or to retract the piston, ahydraulic liquid control valve optionally serving with the hydraulic controlsub-assembly as a throttle to control the speed of all hydraulic motions, and/ora combined hydraulic power source and distribution sub-assembly, comprising,in turn, a hydraulic pump, a motor to drive the hydraulic pump, a hydraulicliquid tank, a housing to secure together the hydraulic pump, motor, and tank inconveniently handled power pack, and hydraulic hoses and fittings to conducthydraulic liquid to and from the often remotely located power pack, during thedistribution of the hydraulic liquid, via the hydraulic control sub-assembly, tothe hydraulic cylinder sub-assembly and to the hydraulic driving power unitsub-assembly, when earth core samples are being taken during soil testingoperations, and in other embodiments using a pneumatic system, and for abasic power source, using either gasoline or diesel engines, or electricalmotors.
