Embodiment 1

[0028] Embodiment 1: as figure 1 As shown, the present invention includes a drill tube 2, a base 1, a connecting seat 3 and a drill rod 4, the connecting seat 3 and the base 1 are respectively installed at both ends of the drill tube 4, and the drill rod 4 is connected to the connecting seat 3.

[0029] Such as Figure 3 ~ Figure 5 As shown, the drill pipe 2 includes a connecting sleeve 5 and a cylinder body 6 connected to each other. The radius of the connecting sleeve 5 is larger than that of the drill cylinder body 6. Two through holes 7 are opened on the connecting sleeve 6 along the same central axis. It is used to fix the drill tube 2 and the connecting seat 2; the cylinder body 6 is a cylindrical shape formed by two interlocking semicircles, and the lower edge of the drill tube 2 is a cutting edge, which is used to cut the soil when collecting the original pattern; There is an arc-shaped groove 8 along the circumference on the upper cylinder 6, which is used to place a...

Embodiment 2

[0034] Embodiment 2: as figure 2 As shown, this example includes a drill barrel 2, a base 1, a connecting seat 3 and a drill pipe 4, the connecting seat 3 and the base 1 are respectively installed at both ends of the drill barrel 4, the drill pipe 4 is connected with the connecting seat 3, and at the connecting seat 3 An extension rod 16 is also installed between the connecting rod 11 and the drill rod 4 .

[0035] Such as Figure 12 , Figure 13 As shown, the two ends of the extension rod 16 are respectively a structure matched with the end of the connecting rod 11 of the connecting seat 3 and the lower end of the drill rod 4, with a structure for fixing the extension rod 16 and the connecting rod 11, The sleeve 17 of the drill pipe 4 or other extension rod connection ends. Such as figure 2 As shown, it is a schematic diagram of connecting the drill barrel 2, the connecting seat 3, the drill pipe 4 and the extension rod 16 in order. According to the collection depth of ...

Abstract

The present invention relates to a hand-holding original-state pillar collecting device belonging to the technical field of drilling, which comprises a drilling barrel, a base seat, a connection seat and a drilling rod, wherein the connection seat and the base seat are respectively arranged at both ends of the drilling barrel, and the drilling rod is connected with the connection seat. The drilling barrel is combined by two semi circles through grooves mutually engaged in a sliding way. When compacted soil samples are collected, two parts of a barrel body can be separated to obtain better original-state soil samples. When loose soil samples are collected, the drilling barrel can be directly used as a container to study and test the performance of original soil, while soil does not need to be taken out, and thus, the damage for original-state soil samples is avoided. A plurality of drilling barrels can be superposed to form required original-state pillars, so not only original-state pillars can be collected well, but also the collected original-state pillars are convenient to move and do other follow-up work. In a use process, soil sections do not need to dig, and original-state soil samples which are required to have deep inner sections can be obtained. Digging work for collecting field original-state soil samples is reduced.

Description

technical field [0001] The invention belongs to the technical field of drilling, and is a hand-held undisturbed soil column collection device, which is used for collecting soil analysis samples, soil observation and description samples and collecting soil columnar samples, and is suitable for teaching, scientific research and production departments related to soil. Background technique [0002] In the prior art, according to different sampling methods, there are three types of soil drilling drills: direct pressure type, spiral type and hammer pressure type. Regardless of the type of soil drill, the external force is used to make the drill body enter the soil to achieve the purpose of soil extraction. As long as the structure is reasonable, ideal undisturbed soil samples can be obtained by any sampling method. But no matter the direct pressure type, or the drill body of the rotary or hammer drill, an opening of different sizes is opened on the wall of the drill tube to take ...
