A connecting rod 2, fig. 4 is an enlarged schematic view of the connecting rod in fig. 1, and referring to fig. 1 and 4, the connecting rod is a hollow structure connected between the handle 1 and the drill bit, and two L-shaped steel wires 8 are arranged in the connecting rod; the vertical parts of the two L-shaped steel wires 8 are all arranged in the connecting rod in a penetrating mode, the tops of the two L-shaped steel wires penetrate through the hollow structure of the handle and are connected with a winch on the handle, and the horizontal parts of the two L-shaped steel wires are arranged at the upper cross section position and the lower cross section position of the transparent organic glass soil column 7 respectively and are used for cutting soil of the upper cross section and the lower cross section of the transparent organic glass soil column 7. Wherein, rotating the winch 4, the winch 4 drives the horizontal part of the L-shaped steel wire 8 to cut the soil body of the corresponding section of the transparent organic glass soil column 7. The steel wire of the upper section of the transparent organic glass soil column can be used for cutting the soil of the upper section, and the steel wire of the lower section of the transparent organic glass soil column can be used for cutting the soil of the lower section.
When the large burial depth soil sampling device is used for carrying out concrete soil sampling operation, the drill bit can be drilled into the soil with large burial depth through the rotating handle 1, so that the drill bit can sample soil, and the transparent organic glass soil column 7 in the drill bit can also obtain the soil. Wherein, because there is the space between the upper and lower cross-section of transparent organic glass earth pillar 7 and the upper and lower cross-section of drill bit, thus, when the drill bit takes out from the soil of big buried depth, wherein the soil body also can pass transparent organic glass earth pillar 7, so be located the soil between transparent organic glass earth pillar 7 and the drill bit and can keep the pressure of the inside soil of transparent organic glass earth pillar, even if soil in the transparent organic glass earth pillar 7 arrives subaerially along with the drill bit, it still can be in fact by on the transparent organic glass earth pillar cross-section and unnecessary soil pressurization under the cross-section down, the pressure value of soil in the transparent organic glass earth pillar and the original pressure value under the big buried depth environment change very little this moment, therefore can consider the same, thereby avoid the soil of sampling to arrive the inflation because of losing pressure after the ground, cause the distortion of soil parameter, be unfavorable for the problem of soil analysis. Moreover, soil bodies on the upper and lower sections of the transparent organic glass soil column can also ensure that soil in the transparent organic glass soil column is not easy to damage, so that the problem that the damaged soil body needs to be repaired before a subsequent test is carried out by utilizing a soil sample is solved.
In addition, because the soil to be analyzed is the soil in the transparent plexiglass column 7, the redundant soil above the upper cross section and below the lower cross section of the transparent plexiglass column 7 needs to be removed before the soil analysis, and the horizontal part 8 of the steel wire can be contracted by rotating the winch 4, so that the redundant soil is cut off, and the soil in the transparent plexiglass column 7 for the soil analysis is obtained.
By means of the technical scheme of the embodiment of the invention, after soil taking is completed, soil in the transparent organic glass soil column is pressurized by soil above the upper section and below the lower section of the transparent organic glass soil column 7 in the drill bit, so that the problems that soil bodies on two sides of a cutting ring are easy to damage and need repairing before testing in the conventional cutting ring soil taking process are solved, and meanwhile, the problem that soil taken from a large buried depth environment expands due to no external pressure when reaching the ground, so that the soil parameters are distorted is solved; meanwhile, the horizontal part of the L-shaped steel wire corresponding to the upper and lower sections of the transparent organic glass soil column 7 is arranged, so that when the drill bit is taken out of the soil, the soil body at the upper and lower sections of the transparent organic glass soil column 7 in the drill bit is cut by the horizontal part of the L-shaped steel wire corresponding to the upper and lower sections of the transparent organic glass soil column 7, a required soil sample with original pressure in the transparent organic glass soil column is obtained, and the accuracy of soil parameter analysis can be guaranteed.

The horizontal part of one L-shaped steel wire is fixed in an annular groove corresponding to the upper section of the transparent organic glass column 7, and the horizontal part of the other L-shaped steel wire is fixed in an annular groove corresponding to the lower section of the transparent organic glass column 7. After cutting soil, the horizontal part shrink of two L type steel wires is finished, so it can become less annular or directly shrink for solid disc, at this moment, in order not to influence operations such as removing transparent organic glass earth pillar, can be fixed in the inside groove of drill bit inboard opening part with the horizontal part of two L type steel wires after the shrink. In the embodiment of the present invention, the inner groove may be disposed in other available areas of the drill bit as required, or the horizontal portion of the retracted L-shaped steel wire may be fixed by any other available means or devices, which is not limited in this embodiment of the present invention.
Furthermore, in the embodiment of the present invention, after the cut transparent plexiglas column is taken out of the drill and before the drill with the empty transparent plexiglas column is implanted into the soil again to collect the soil, the winch is controlled to perform corresponding operations to release the horizontal parts of the two contracted L-shaped steel wires, reduce the horizontal parts of the two L-shaped steel wires into a ring shape, and correspondingly move and fix the horizontal parts of the two L-shaped steel wires from the inner groove of the inner layer of the drill to the grooves corresponding to the upper and lower sections of the transparent plexiglas column.
Like this, when steel wire 8 did not use, can make steel wire 8 have the position that can block in the drill bit, avoid when soil sampling device removes, this steel wire takes place to rock and damages each part that can collide or influence the effect of gathering soil inside the drill bit.
The horizontal part of the steel wire is fixed on the inner side of the drill bit, so that the manufacturing cost of the soil sampling device can be saved, and more notches can be prevented from being arranged in the drill bit with smaller volume; of course, in different embodiments, a person skilled in the art may also arrange other components inside the drill according to actual needs, which can clamp the steel wire 8 when the steel wire 8 is not used, as long as the steel wire 8 can be kept from shaking, and the invention is not limited to this.
Optionally, in another embodiment, the outer diameter of the clear perspex column 7 is the same as the drill bit inner diameter; the transparent organic glass earth pillar is fixed in the drill bit is inside and is laminated with the drill bit inner layer that the opening corresponds. Correspondingly, in this embodiment, refer to fig. 1 and fig. 3, so the user can put into the drill bit back with transparent organic glass earth pillar through the opening of drill bit, and the drill bit can the snap-on in the drill bit inside and laminate with the drill bit inlayer that the opening corresponds to can need not adjust the position of transparent organic glass earth pillar again, reduce user's operation, also less in addition set up more notch in the drill bit inboard. Of course, in the embodiment of the present invention, a notch for fixing the column of clear plexiglas may be provided on the inner side of the drill, or any other available fixing method or device may be used to fix the column of clear plexiglas in the drill, which is not limited to this embodiment of the present invention.
Optionally, in one embodiment, the connection between the handle and the connecting rod has an inner surface thread and an outer surface thread respectively; the connecting rod and the drill bit are respectively provided with an inner surface thread and an outer surface thread at the connecting part. Referring to fig. 1, in the present embodiment, the connecting rod may be connected to the handle and the drill bit by threads, respectively, and then there are inner surface threads and outer surface threads, respectively, at the connection of the handle and the connecting rod; the connection of the connecting rod to the drill bit also has internal and external surface threads, respectively. For example, where the handle is connected to the connecting rod with internal threads, then where the connecting rod is connected to the handle with external threads; whereas if the connection to the connecting rod in the handle has an outer surface thread, the connection to the handle in the connecting rod has an inner surface thread. Of course, in the embodiment of the present invention, the handle and the connecting rod and the drill and the connecting rod may be connected by any other available method, such as inserting, and the connection manner between the handle and the connecting rod and the connection manner between the drill and the connecting rod may be different or the same, and the embodiment of the present invention is not limited thereto.
Alternatively, in this embodiment, referring to fig. 1 and 4, the connecting rod 2 according to an embodiment of the present invention may include a plurality of sub-connecting rods 2a, 2b, 2c that are threadedly connected. Wherein, to arbitrary sub-connecting rod, the junction of its one end has the surface screw thread, and the junction of the other end has the internal surface screw thread, can guarantee like this that arbitrary two sub-connecting rods are supporting to be connected.
Optionally, in this embodiment, referring to fig. 1 and 3, the transparent organic glass column is marked with capacity scales, and the capacity scales are increased from any cross section to another cross section along the side surface of the transparent organic glass column. Then the user can use the capacity scale on the transparent organic glass earth pillar as the reference after having obtained transparent organic glass earth pillar, takes out the soil of corresponding volume in order to carry out subsequent operation from transparent organic glass earth pillar to avoid the user still need measure the soil of corresponding volume again, reduced user operation. The volume scale can be sequentially increased by pointing to another section by taking any section of the transparent organic glass soil column as a reference, and parameters such as specific units, scales and the like of the volume scale can be set according to requirements, so that the embodiment of the invention is not limited.
Alternatively, in another embodiment, the L-corner portions of the two L-shaped steel wires are arc-shaped, and the L-corner portions have smooth surfaces, so that when the horizontal portion of the steel wire is cutting soil, since the horizontal portion is in direct contact with the soil of the upper and lower sections of the clear plexiglas column, if the L-corner portions are right-angled, the right angle is easily worn to break the steel wire. Therefore, in the present embodiment, the L-shaped corner portion is formed in a circular arc shape, so that the corner portion is prevented from being in direct contact with cut soil or other portions, thereby prolonging the service life of the steel wire.
Accordingly, referring to the embodiment shown in fig. 1 and 3, the L-shaped corner portions of the L-shaped steel wires 8 are formed in a circular arc shape, so that the service life of the steel wires 8 can be prolonged.
