Description
55~
This invention relates to soil sampling equipment.
It is frequently desirable to obtain samples of soils in various areas and at varying depths for analysis. In most operations in which the soil sample is required, speed and convenience in obtaining the sample whereby a large number of samples may be obtained in a short period of time are prime factors.
In investigations of the distribution, type and physical proper-~ ties of the soil below ground sur:~ace level, it is often desirable to 7 be able to extract continuous, preferably undisturbed7 samples of soil.
The sampling method of sub-surface exploration provides practically con-tinuous and representative samples of the sub-soil and is probably the best ~ method yet devised for obtaining detailed and reliable information on the ,~ characteristcs of the sub-soil. A common and efficient type of sampler is the drive sampler which consists essentially of a tube which is ,~ advanced into the soil in the axial direction. There are various types of . ~ .
drive sàmplers 1n general use and these may be broadly classified in two groups, namely, open samplers and piston samplers. In the case of open samplers, the tube is always open at the lower end; the soil enters the tube as soon as it is forced into the ground. With piston samplers, on 0~ ~ the other hand, the lower end of the tube is temporarily sealed,as by a ; 20 piston or a plug, so that soil can be prevented from entering the sarnpler until it has been driven into the soil to the desired sampling depth.
; At that depth, the piston is released or retracted o that further advance of the sample into the soil forces a sample into the lower end of the tube.

Canadian Patent No. 623,475 issued July 11, 1961 to P.J. Parsons provided a soil sampling device comprising a tubular drill rod having at ~; least one soil sample-receiving opening in the side wall thereof, a piston assembly in the drill rod and having a pair of spaced connected pistons providing a soil sample-receiving chamber therebetween.

Andersson provided soil sampling equipment of the retracted-piston type which could be operated by means of a single line of extensions, thereby materially reducing the advancing and withdrawal time. Such equipment consisted of the combination of a tubular housing, a sample tube detach-ably connected at its upper end to the housing and formed at its lower end with a cutting edge, and a piston slidably mounted within the sample tube and adapted to seal off the lower end thereof. A piston rod was con-nected to the upper end of the piston and extended upwardly through the sample tube and the housing, the piston rod being formed at its upper end with an enlarged head portion adapted with the piston in its fully extended position, to engage the upper edge of the housing, so that downward pres-sure applied to the upper end of the rod would be transmitted to both the housing and the piston. A plurality of arcuate lugs were on the rod and were spaced apart longitudinally thereof. A plurality of arcuate segments were formed on the inner surface of the housing and were likewise spaced apart longitudinally thereof. The lugs and the segments were adapted to cooperate releasably to lock the rod and the housing in downwardly drivable engagement upon partial retraction of the piston through the sample tube, and in upwardly drivable engagement upon further retraction of the piston to its fully retracted position. A plurality of stop members were provided on the inner surface of the housing intermediate of the arcuate segrnents, the stop members cooperating with the arcuate lugs to limit the rotational rnovement of the rod relative to the housing, thereby to facilitate align-ment of the lugs and the segments for intercoupling the rod and the

Figure 6 is a vertical cross-section of the soil sampling device of another aspect of this invention.
As seen in Figures 1 and 2, the soil sampling device 10 is mounted on a pick-up truck l.l~by means of a universal mounting 12 constituted by a pair of angle arms rigidly secured at a right angle to one another with one arm (ulmumbered)~extending along the longitudinal length of the bed of the truck, and a second arm 14 extending along the transverse width of the bed of the truck, with the angle arms being attached by bolts 13a to the existing stake pockets of the pick-up truck. Secured to the universal mounting is a power box 16 containing ~therein an electrically powered motor 17 to provide hydraulic fluid ; under pressure by means of hydraulic pump 17a. The electrical con-nection to the~power box lS in the form of a control box system 18, oDtD;which the operating controls are attaehed, the actual connection ~ 20 ~ being~by means of a female plug l9/male plug 20 connection. Suitable ;; wires namely, 22, 23 and 24 from a 12-volt battery (not shown) to the control box 1~, 21~from the battery (not shown) to the motor 17, and 21a between the control box 18 and the motor 17, are also shown.
As seen in Figure 4, secured to the universal mounting 12 is the casing 25 of hydraulic cylinder 26, sheathed by a protective box 27. The securement is by means of a saddle 30 secured by a T-bar 31 to ,. . . . . .

spaced-apart fixed hollow rectanc3ll1al- yuide sleeves 32.
The free rod end 33 of the hydraulic cylinder 26 is secured to a collar 34 of an open cage 35, witllin which is secured hydraulically powered rotary motor 36, which motor is provided with a pair of hydraulic feed lines 37. The cage 35, includes upper and lower plates 38 inter-connecting a pair of hollow rectangular guide rods 39 slidable along guide rods 40, whereby the motor 36 is vertically slidable along the guide rods 40. The motor 36 drives an auger 41 which is threaded to the drive shaft (not shown) of the motor 36 to provide a positive yet easily changed connection. If desired, the auger 41 may be mounted by means of safety shear pin 42 to minimize auger damage.
Thus, the auger 41 is rotatably driven (by the rotary motor 36 as well as being vertically oscillatable by the rod 33 of the hydraulic cylinder 36.
~ yoke 43a is also secured to the rod 33 of the hydraulic cylinder 26, an adjustable preselected distance, e.g. about 8", above ; ~ the collar 34. Yoke 43a is secured to rods 40 which are in turn secured to the fixed portlon~44~of the soil sample box 45. Yoke~43a and rods 40 are mounted to slide with respect to guide sleeves 32 between an upper : ~ :
limit, where the yoke 43a abuts the end of casing 25 of hydraulic cylin-der 26, and a lower limit, where the soil sample box rests atop the soil.
Thus, the hydraulic cylinder rod 33 provides vertical oscillation of the ,.
soil sample box 45 as well.
The soil sample box 45 includes a fixed portion 44 including a top wall 47 and a front wall 48. A removable portion of the sample box is provided which includes a pair of side walls 49, a rear wall 50 and a bottom wall 51. The top wall 47 and bottom wall 51 are provided with I 1, _ '.:~'' ' -' ' ' :

aligned apertures 52, 53 te .~ccommo~ t~ rlle au~er ~perturc 53 is surrounded by cylinder 54.
In use, activation of the llydraulic cylinder 26 provides a co-operative vertical movement and forces the soil sample box 45 to the ground level and at the same time forces the auger 41 through the soil sample box to the preselected depth (i.e., 8"3 into -the soil which is equal to the adjustable spacing between the yoke 43a and the collar 34. The rotation of the auger 41 provides a self-feeding of the sample into the soil sample box 45. This generally takes less than 30 seconds.
The hydraulic cylinder 26 is activated in the reverse direction to raise the auger 41 and the soil sample box 45 above the ground. In this position, the soil sample box 45 is approximately 16" above the ground. The soil samples may now be taken from the soil sample box by withdrawing the removable portion.
The embodiment of Figures S and 6 includes the same mounting frame and hydlaulic system as that of Figures 1-4. The bottom portion includes a probe tube 120 secured to the free rod end 133 of the hydrau-lic cylinder 126. The probe tube 120 includes a mouth 111 so that the diameter of the core sample is less than the diameter of the probe tube ~20 120. The probe tube 12~ is provided with three spaced-apart, vertical, soil removal slots 113, 114, llS, each provided selectively with a hand-operated baffle 116, 117, lI8 and 119. The upper such slot 113 is pro-vided with baffles 116, 117, 118; the end slot 114 is provided with baffles 117 and 118; and the lower such slot is provided with baffles 118 and 119.
The probe tube 120 is encased by a cylinder 110 which is secured to the cylinder rod 133 at a location above the probe tube 120.

The cylinder 110 is verticallv ~v 8~l~ hctw~cn a rest position out of contact with the soil, and a 10WeL pOsitioll positioned atop the soil.
The cylinder 110 is provided with a frusto-conical open end 112 through which the probe tube 120 is adapted to be forced into the soil.
In use, activation of the hydraulic cylinder forces the cylinder 110 into contact with the soil and forces the probe tube 120 a selected distance into the ground. Withdrawal of the cy]inder 110 and the probe tube 120 brings with it an undisturbed core of soil sample. The upper 10 113, mid 114 and/or lower 115 strata of the core can be separately re-moved through use of the respective slots and hand-operated baffles 117, 118, and 119.

aligned apertures 52, 53 te .~ccommo~ t~ rlle au~er ~perturc 53 is surrounded by cylinder 54.
In use, activation of the llydraulic cylinder 26 provides a co-operative vertical movement and forces the soil sample box 45 to the ground level and at the same time forces the auger 41 through the soil sample box to the preselected depth (i.e., 8"3 into -the soil which is equal to the adjustable spacing between the yoke 43a and the collar 34. The rotation of the auger 41 provides a self-feeding of the sample into the soil sample box 45. This generally takes less than 30 seconds.
The hydraulic cylinder 26 is activated in the reverse direction to raise the auger 41 and the soil sample box 45 above the ground. In this position, the soil sample box 45 is approximately 16" above the ground. The soil samples may now be taken from the soil sample box by withdrawing the removable portion.
The embodiment of Figures S and 6 includes the same mounting frame and hydlaulic system as that of Figures 1-4. The bottom portion includes a probe tube 120 secured to the free rod end 133 of the hydrau-lic cylinder 126. The probe tube 120 includes a mouth 111 so that the diameter of the core sample is less than the diameter of the probe tube ~20 120. The probe tube 12~ is provided with three spaced-apart, vertical, soil removal slots 113, 114, llS, each provided selectively with a hand-operated baffle 116, 117, lI8 and 119. The upper such slot 113 is pro-vided with baffles 116, 117, 118; the end slot 114 is provided with baffles 117 and 118; and the lower such slot is provided with baffles 118 and 119.
The probe tube 120 is encased by a cylinder 110 which is secured to the cylinder rod 133 at a location above the probe tube 120.

The cylinder 110 is verticallv ~v 8~l~ hctw~cn a rest position out of contact with the soil, and a 10WeL pOsitioll positioned atop the soil.
The cylinder 110 is provided with a frusto-conical open end 112 through which the probe tube 120 is adapted to be forced into the soil.
In use, activation of the hydraulic cylinder forces the cylinder 110 into contact with the soil and forces the probe tube 120 a selected distance into the ground. Withdrawal of the cy]inder 110 and the probe tube 120 brings with it an undisturbed core of soil sample. The upper 10 113, mid 114 and/or lower 115 strata of the core can be separately re-moved through use of the respective slots and hand-operated baffles 117, 118, and 119.
