AI Technical Summary
Most existing ring-type soil samplers require mechanical or electric drive, making them inflexible to operate and difficult to perform soil sampling quickly and accurately.
A manual drop hammer type ring cutter soil sampler was designed, including a sleeve rod, a cap, a drop hammer, a rigid sleeve cover, and a directional base. The drop hammer moves up and down along the sleeve rod under gravity, and the ring cutter is driven vertically into the soil. The verticality is ensured by a level, which simplifies the operation process.
It improves the efficiency and accuracy of soil sampling, reduces manpower input, minimizes the labor intensity of operators, has a simple structure, and makes sampling quick and convenient.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of soil test, specifically relates to a hand drop hammer type cutting ring soil sampler. BACKGROUND
[0002] Currently, two indexes of compaction coefficient and bearing capacity are usually used to control the quality of earthwork backfill. Specifically, when there is no building or structure on the upper part of backfill soil, the compaction coefficient is used to control the quality, and when there is a building or structure on the backfill soil, the compaction coefficient and the bearing capacity need to be controlled. The compaction coefficient is the ratio of the compaction density of backfill soil to the maximum dry density, wherein the compaction density is directly measured on site, and the maximum dry density is measured in the laboratory. Whether the compaction density or the maximum dry density of backfill soil is tested, soil needs to be taken on site.
[0003] The existing soil sampling tools mainly include drilling type, sampler type and cutting ring type, etc. Among them, the cutting ring type soil sampler has the advantages of high sampling efficiency, simple operation and good sample quality, and is widely used in the fields of agriculture, environmental protection, geological exploration, etc. However, most of the cutting ring type soil samplers on the market need to use mechanical or electric devices for driving, and the operation is not flexible enough.
[0004] Therefore, the present inventors propose a hand drop hammer type cutting ring soil sampler. SUMMARY
[0005] In view of the defects of the prior art, the utility model aims to provide a hand drop hammer type cutting ring soil sampler which is flexible to operate and can quickly and accurately sample soil, thereby improving the sampling efficiency.
[0006] The utility model adopts the technical scheme as follows: a hand drop hammer type cutting ring soil sampler, including sleeve rod, cutting ring, setting in sleeve rod top sleeve cap, sliding sleeve setting in sleeve rod drop hammer, and setting in sleeve rod bottom rigid sleeve cover, sleeve rod passes through drop hammer and is welded with rigid sleeve cover, drop hammer slides along sleeve rod axial direction so as to control the depth of ramming, cutting ring sets up on the upper part of rigid sleeve, rigid sleeve and rigid sleeve cover are mutually adapted, the bottom of rigid sleeve is connected with directional base, directional base is used for fixing the position of cutting ring, the bottom of directional base is provided with adjustable supporting leg, directional base is also provided with level on.
[0007] Further, the adjustable supporting leg is threadedly connected with the directional base.
[0008] Further, the directional base is provided with a positioning hole in the center, the hole diameter of the positioning hole is consistent with the outer diameter of the cutting ring; the directional base is welded with the rigid sleeve, and the inner diameter of the rigid sleeve is consistent with the outer diameter of the cutting ring.

[0010] The hand-operated falling hammer type ring knife soil sampler has the following beneficial effects: BRIEF DESCRIPTION OF DRAWINGS
[0011] Fig. 1 The utility model provides a hand-operated falling hammer type ring knife soil sampler.
[0012] Fig. 2 The utility model provides a hand-operated falling hammer type ring knife soil sampler.
[0013] In the figure: 1. cover, 2. sleeve rod, 3. falling hammer, 4. rigid cover, 5. rigid sleeve, 6. directional base, 7. adjustable support foot, 8. level, 9. ring knife, 10. positioning hole. DETAILED DESCRIPTION
[0014] The utility model will be further explained and described below in connection with the drawings and examples.
[0015] Example 1
[0016] As Figs. 1-2 shown, a kind of hand-operated falling hammer type ring knife soil sampler, including sleeve rod 2, ring knife 9, set in the cover 1 of sleeve rod 2 top, falling hammer 3 is slidably placed in sleeve rod 2, and rigid cover 4 is set in the bottom end of sleeve rod 2, sleeve rod 2 passes through falling hammer 3 and is welded with rigid cover 4, falling hammer 3 slides along the axial direction of sleeve rod 2 to control the depth of compaction, ring knife 9 is built-in in the inside upper portion of rigid sleeve 5, rigid sleeve 5 is mutually adapted with rigid cover 4, the bottom of rigid sleeve 5 is connected with directional base 6;Directional base 6 is used to fix the position of ring knife 9 to ensure the accuracy of sampling;Directional base 6 bottom is provided with adjustable support foot 7;Level 8 is fixed on directional base 6, guarantees that ring knife 9 is vertically entered into soil when taking soil, avoid the problem of causing soil sample disturbance.Ring knife soil sampler material uses stainless steel.
[0017] Falling hammer 3 is used to provide the impact force of falling, and ring knife 9 is inserted into soil and sampled.When the surface of rigid cover 4 is flush with rigid sleeve 5, meet the depth of taking soil.
[0018] In use, the operator places the directional base 6 of the manual drop hammer type cutting ring soil sampler on the soil surface, and uses the rigid sleeve 4 to control the sampling depth. Then, the operator adjusts the adjustable support foot 7 to ensure that the level 8 is horizontal, lifts the drop hammer 3 to a certain position on the sleeve 2, so that it is separated from the rigid sleeve 4, and the cutting ring 9 is inserted into the soil by gravity, and the soil sampling is completed.
[0019] After the sampling is completed, the operator can easily take out the cutting ring 9 to obtain the soil sample without additional steps and tools. Therefore, the manual drop hammer type cutting ring soil sampler has the characteristics of simple structure, convenient operation and efficient preparation of soil samples, reduces waste and improves sampling efficiency.
