Description

[Technical field]

[0001] The utility model belongs to the technical field of soil sampling, and in particular relates to a soil sample collecting device. [Background technology]

[0002] In the field, rock and soil sampling and exploration requires the use of a sampler to dig the ground. For rock and soil sampling at a certain depth, the sampler is generally inserted directly into the soil surface for sampling. During the sampling process, in order to make the sampler more stable and labor-saving, a fixed cone is usually provided to fix the sampler on the soil surface. For example, a mineral exploration raw soil sampler disclosed in the utility model patent with publication number CN213902939U fixes the entire sampler on the soil surface through a fixed shaft when in use. After the sampling tube is sampled, since it and the fixed shaft are both mounted on a mounting frame, the fixed shaft needs to be pulled out of the soil surface at the same time. When the next sampling is performed, the fixed shaft needs to be reinserted into the soil surface to fix the mounting frame, which is very inconvenient to use. [Utility Model Content]

When in use, the stand is fixed on the soil surface to be sampled by the supporting and fixing mechanism, and sampling is performed by the sampling mechanism, which is not only more stable and labor-saving, but also after the sampling mechanism has completed sampling, the sampling mechanism can be detached from the stand through the detachable connecting mechanism to unload the soil. At this time, the stand and the supporting and fixing mechanism are still fixed on the soil surface. When sampling is performed again, the sampling mechanism can be directly reinstalled on the stand by the detachable connecting mechanism, which is very convenient to use.

[0034] Specifically, the detachable connection mechanism 4 includes: a detachable mounting member 41, which is arranged on the stand 1, and the sampling mechanism 3 is arranged on the detachable mounting member 41; a first movable fixing member 42, which is provided with a first limiting fixing groove 421, and one end is hinged on the stand 1; a second movable fixing member 43, which is provided with a second limiting fixing groove 431, and one end is hinged on the stand 1, and the second movable fixing member 43 and the first movable fixing member 42 can be relatively rotated to close and dock, or rotated back to back to unfold; when the second movable fixing member 43 and the first movable fixing member 42 are relatively rotated to close, the edge of the detachable mounting member 41 is located in the first limiting fixing groove 421 and the second limiting fixing groove 431 to fix the detachable mounting member 41. That is, the detachable installation of the detachable mounting member 41 and the sampling mechanism 3 arranged thereon is realized.

[0035] In addition, a first fixing ear 51 is provided at one end of the first movable fixing member 42 away from the hinged end, and a second fixing ear 52 is provided at one end of the second movable fixing member 43 away from the hinged end.

[0036] Further, the stand 1 includes an annular support plate 11, an annular mounting plate 12 relatively arranged above the annular support plate 11, and a height adjustment mechanism 13 arranged between the annular support plate 11 and the annular mounting plate 12 for adjusting the distance between the annular support plate 11 and the annular mounting plate 12. The detachable connection mechanism 4 is arranged on the annular mounting plate 12. When the detachable mounting member 41 is installed on the annular mounting plate 12, the sampling mechanism 3 on the detachable mounting member 41 passes through the annular mounting plate 12 and the annular support plate 11 in sequence. According to the actual working environment, the distance between the annular mounting plate 12 and the annular support plate 11 is adjusted by the height adjustment mechanism 13 to facilitate sampling by the sampling mechanism 3.

[0037] More specifically, the height adjustment mechanism 13 includes a height adjustment screw 131 threadedly connected to the annular support plate 11, an adjustment ball 132 provided at one end of the height adjustment screw 131 close to the annular mounting plate 12, and an adjustment sleeve 133 provided on the annular mounting plate 12 and rotatably connected to the adjustment ball 132.

[0038] Further, there are a plurality of height adjustment screws 131, and the plurality of height adjustment screws 131 are arranged along the circumference of the annular support plate 11. By adjusting different height adjustment screws 131, the parallelism between the annular mounting plate 12 and the annular support plate 11 can be adjusted.

[0039] Furthermore, the sampling mechanism 3 includes a sampling screw 31 threadedly connected to a detachable mounting member 41, a sampling rotating handle 32 provided at one end of the sampling screw 31, and a sampling spiral blade 33 provided at the other end of the sampling screw 31. The sampling rotating handle 32 is rotated to drive the sampling screw 31 to rotate relative to the detachable mounting member 41, that is, to drive the spiral blade 33 to rotate up and down to extend into or withdraw from the soil surface, thereby achieving soil sampling.

[0040] Specifically, the support and fixing mechanism 2 includes a plurality of support rods 21 arranged along the circumference of the annular support plate 11, and a fixing member 22 arranged at one end of the support rods 21 away from the annular support plate 11. The fixing member 22 is fixed on the soil surface, and the support rods 21 support the stand 1, so that the stand is stable and does not swing during sampling, which is convenient for sampling.

[0041] More specifically, the support rod 21 is hinged on the annular support plate 11, and a limiting protrusion 211 is provided at the hinged end of the support rod 21 and the annular support plate 11, and the limiting protrusion 211 is used to limit the support rod 21 from turning upward relative to the annular support plate 11. When not in use, the support rod 21 can be turned inward and folded for easy carrying, and when in use, the support rod 21 is turned outward and unfolded, and is limited by the limiting protrusion 211 to achieve supporting the stand 1.

[0042] Further, the fixing member 22 includes an insertion portion 221, an annular receiving groove 224 circumferentially arranged outside the insertion portion 221, a plurality of arc-shaped limiting claws 222 circumferentially hinged in the annular receiving groove 224, a toggle portion 223 rotatably arranged on the insertion portion 221, and a connecting rod connecting the toggle portion 223 and the arc-shaped limiting claws 222. When the toggle portion 223 is toggled, the connecting rod drives the arc-shaped limiting claws 222 to rotate, so as to drive the plurality of arc-shaped limiting claws 222 to rotate and expand or be stored in the annular receiving groove 224. When in use, the arc-shaped limiting claws 222 are stored in the annular receiving groove 224. After the insertion portion 221 is inserted into the soil, the toggle portion 223 is toggled to rotate and expand the arc-shaped limiting claws 222 through the connecting rod, so that the fixing member 22 is firmly fixed in the soil.
