[0027] By setting the mounting plate 4 and the cooperation between the positioning column 41, the sliding groove 42 and the positioning groove 43, the soil can be effectively prevented from entering the collection cavity by setting the mounting plate 4 at the bottom of the sampling cylinder 1 during work, the soil can be stably rotated and discharged through the flow guide groove 2 at the outer edge of the sampling cylinder 1, and after reaching the specified depth, the horizontal rod 8 is counterclockwise rotated, the supporting rod 3 and the connecting rod 5 connected with the horizontal rod 8 are synchronously rotated during the rotation of the horizontal rod 8, the horizontal rod 8 is lifted upward when the positioning column 41 is separated from the positioning groove 43, the positioning column 41 slides upward along the sliding groove 42, the horizontal rod 8 is clockwise rotated after the mounting plate 4 rises to a certain height, and the positioning column 41 is reconnected and fixed in the positioning groove 43, so as to form a collection cavity for the soil to enter, thereby facilitating subsequent sampling, combining punching and sampling organically, and effectively preventing the mud in the upper sampling hole from falling to affect the accuracy of the subsequent sample.

[0028] The top of the supporting rod 3 and the top of the connecting rod 5 are provided with an insertion groove 10, the bottom of the connecting rod 5 is provided with an insertion block 6 matched with the insertion groove 10, the bottom of the fixing rod 7 is provided with an insertion column 12 matched with the insertion groove 10, the insertion block 6 and the insertion column 12 are provided with positioning holes, the supporting rod 3 and the connecting rod 5 are provided with a communication hole communicated with the insertion groove 10, and the communication hole is provided with a positioning bolt 13, the positioning holes and the positioning bolt 13 are matched and positioned, and the supporting rod 3, the connecting rod 5 and the fixing rod 7 are designed to be detachably extended, so that the overall length of the device can be conveniently adjusted according to the required depth of the sampling hole.

[0029] The outer side of the connecting rod 5 and the outer side of the fixing rod 7 are embedded with a scale plate 18, and the scale plate 18 is marked with an angle scale line, so that the overall length of the device can be roughly understood during work, and the corresponding depth of the sampling hole can be conveniently understood.

[0030] Referring to Figure 1 , Figure 2 and Figure 4 , a blocking frame 11 is installed between the connecting rod 5 and the fixing rod 7, the blocking frame 11 is provided with an observation hole for the insertion column 12 to penetrate, the blocking frame 11 is in the shape of a cross, a stepping assembly 14 for auxiliary impact is installed on the fixing rod 7, the stepping assembly 14 comprises a fixed plate 16 fixed on the fixing rod 7 and a protection cylinder 15 installed on the fixing rod 7, a stepping plate 151 is horizontally fixed on the side of the protection cylinder 15, the protection cylinder 15 is hollow to form an installation cavity, the fixed plate 16 is slidingly arranged in the installation cavity, and a supporting spring 17 is installed in the installation cavity corresponding to the fixing rod 7.

[0031] By cooperating with the blocking bracket 11 and the stepping assembly 14 at the bottom of the fixed rod 7, the foot pedal 151 is stepped down. During the stepping of the foot pedal 151, the mounting plate 4 is snapped into the positioning groove 43, which causes the mounting plate 4 to drive the sampling cylinder 1 to descend as a whole. During the stepping of the foot pedal 151, the protective cylinder 15 is driven down, and the support spring 17 is compressed. After the foot is released, the protective cylinder 15 returns to its original position under the action of the compressed support spring 17. Thus, the stepping method can ensure that the soil can stably enter the sampling chamber, preserve the soil stratification structure, and avoid the situation where the soil stratification structure is unclear during the rotation sampling process.

[0032] A guide bar 71 is vertically protruding from the outer edge of the fixed rod 7, and a guide groove 152 is provided at the top of the protective cylinder 15 for the guide bar 71 to slide. Through the cooperation between the guide bar 71 and the guide groove 152, it can be ensured that the protective cylinder 15 can only move up and down.

[0033] Working principle:

[0034] During the initial installation before work, the plug-in post 12 is inserted into the plug-in slot 10 on the support rod 3, and the blocking frame 11 is fitted onto the plug-in post 12. The support rod 3 and the fixed rod 7 are fixedly connected together by the positioning bolt 13. During work, align with the area to be sampled and turn the horizontal bar 8 clockwise. As the horizontal bar 8 rotates, it drives the fixed rod 7 to rotate as a whole. As the fixed rod 7 rotates, it drives the support rod 3 to rotate as a whole, thereby causing the mounting plate 4 to rotate as a whole. During the rotation of the mounting plate 4, the positioning post 41 on the mounting plate 4 abuts against the positioning slot 43, thereby causing the mounting plate 4 to drive the sampling cylinder 1 to rotate as a whole. During the rotation of the sampling cylinder 1, the soil is cleaned up. The soil can be stably discharged through the guide channel 2 on the sampling cylinder 1.

[0035] When the soil is about to exceed the top of the support rod 3, remove the positioning bolt 13, disassemble the fixing rod 7 and replace the corresponding plug block 6, so that the sample sampling device is extended as a whole. After extension, continue to rotate the device to discharge the soil. When the specified depth is reached, rotate the crossbar 8 counterclockwise. During the rotation of the crossbar 8, the support rod 3 and connecting rod 5 connected to it will rotate synchronously. When the positioning column 41 is disengaged from the positioning groove 43, lift the crossbar 8 upward. At this time, the positioning column 41 slides upward along the sliding groove 42. After the mounting plate 4 rises to a certain height, rotate the crossbar 8 clockwise and make the positioning column 41 snap into the positioning groove 43 again.

[0036] When sampling, the pedal 151 is stepped down, and during the process of stepping down the pedal 151, the mounting plate 4 is clamped and mounted in the positioning groove 43, so that the mounting plate 4 drives the sampling cylinder 1 to step down as a whole, and during the process of stepping down the pedal 151, the protection cylinder 15 is driven to step down, and the supporting spring 17 is compressed, after the foot is released, the protection cylinder 15 is restored to the original position under the action of the compressed supporting spring 17, and the sampling can be repeated by stepping, after a period of sampling, the sampling cylinder 1 can be removed as a whole, and the sampled soil in the sampling cylinder 1 can be moved and extruded to slide out through the mounting plate 4.

[0037] All the technical features in the embodiment can be freely combined according to actual needs.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
