Description

Technical Field

[0001] The utility model belongs to the technical field of geological prospecting equipment and relates to a surface soil sampling device for geological prospecting. Background Art

[0002] Surface soil, especially eluvial and diluvial deposits, is a kind of loose overburden with the widest distribution in metal ore areas. The geochemical anomalies in these soils directly come from the weathering products of ore bodies and surrounding rocks. Therefore, such anomalies have the most definite prospecting significance and play the greatest role in prospecting practice. Sampling and chemical measurement of surface soil not only make the operation more convenient and simple, but also reduce the cost required for prospecting, and the prospecting effect is better. Secondly, the observation of soil sampling profiles also plays an indicative role in geological prospecting. Therefore, during the geological prospecting process, we not only need to sample hard geology such as rocks, but sometimes also need to sample surface soil, which requires the use of soil sampling devices.

[0003] In the prior art, there are various soil sampling devices, but most of their sampling parts cannot be opened. Therefore, when encountering soil with relatively high viscosity, it is difficult to take out and clean the sampled soil after sampling; or the soil must be crushed and loosened, resulting in the inability to observe its profile state. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a surface soil sampling device for geological prospecting aiming at the above problems existing in the prior art, which is intended to facilitate the observation of the soil profile state after sampling.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A surface soil sampling device for geological prospecting, characterized in that the device comprises a first sampling part and a second sampling part, and both the first sampling part and the second sampling part are in the shape of a round shovel; the top ends of the first sampling part and the second sampling part are respectively and sequentially fixed with a first connecting pipe and a second connecting pipe, and the second connecting pipe is inserted into the first connecting pipe; the first sampling part is sleeved outside the second sampling part, and the first sampling part and the second sampling part can be assembled into a cylindrical shape; two handles are fixed at the top of the first connecting pipe, and rubber sleeves are sleeved on each handle; the device further comprises a plurality of bolts, and each bolt can fix the first connecting pipe and the second connecting pipe together.

[0006] Preferably, a connecting sleeve is sleeved on the first connecting pipe, a pedal extends and is fixed to one side of the outer circumference of the connecting sleeve, and the included angle between the top surface of the pedal and the axis of the connecting sleeve is 70° to 80°.

[0007] Advantages of the utility model:

[0008] 1. In this sampling device, both the first sampling part and the second sampling part are in the shape of a round shovel and can be joined together to form a cylindrical structure. Therefore, when they are joined, they can be used for sampling. After separation, it is convenient for us to observe the soil profile and take out and clean the sampled soil inside.

[0009] 2. After this sampling device is disassembled, it can form two independent shovels. When we conduct sampling operations in the wild, we can use it to clean the soil surface until the appropriate sampling depth is reached. The characteristic of its variable structure makes its application scenarios more diverse and more convenient to use.

[0010] 3. In this sampling device, the position of the pedal can be adjusted arbitrarily, enabling us to continuously adjust the position of the pedal according to the change of the sampling depth, making this device more convenient. Description of the Drawings

[0014] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0015] As Figure 1 and Figure 2 shown, a surface soil sampling device for geological prospecting, this device includes a first sampling part 1 and a second sampling part 2, and both the first sampling part 1 and the second sampling part 2 are in the shape of a round shovel; the tops of the first sampling part 1 and the second sampling part 2 are respectively fixed with a first connecting pipe 3 and a second connecting pipe 4 in sequence, and the second connecting pipe 4 is inserted into the first connecting pipe 3; the first sampling part 1 is sleeved outside the second sampling part 2, and the first sampling part 1 and the second sampling part 2 can be joined into a cylindrical shape; two handles 5 are fixed at the top of the first connecting pipe 3, and a rubber sleeve 6 is sleeved on each handle 5; this device also includes a number of bolts 7, and each bolt 7 can fix the first connecting pipe 3 and the second connecting pipe 4 together.

[0016] In this sampling device, the first sampling part 1 and the second sampling part 2 are both in the shape of a round shovel and can be assembled together to form a cylindrical structure. We only need to use bolts 7 (or latches) to fix the first connecting tube 3 and the second connecting tube 4 together, and then hold the handle 5 with both hands and insert the cylindrical structure into the soil, so that part of the soil can be retained in the cylindrical structure to complete the sampling of the soil. After the sampling is completed, we pull it out, then remove the bolt 7 or the latch, pull up or rotate the first connecting tube 3, so that the first sampling part 1 and the second sampling part 2 can be separated or overlapped, which makes it convenient for us to observe the cross-section of the soil. And after the first sampling part 1 and the second sampling part 2 are separated, we can easily take out the soil inside and clean it up to avoid interference with the next sampling analysis.

[0017] After the sampling device is disassembled, it can form two independent shovels. When we conduct sampling operations in the field, we can use them to clean the soil surface until the appropriate sampling depth is reached. Its variable structure makes its application scenarios richer and more convenient to use.

[0018] like Figure 1 and Figure 2 As shown, a connecting sleeve 8 is sleeved on the first connecting tube 3, and a pedal 9 is fixed to one side of the outer periphery of the connecting sleeve 8, and the top surface of the pedal 9 and the axis of the connecting sleeve 8 form an angle of 70° to 80°. In this sampling device, the pedal 9 is arranged on one side of the outer periphery of the connecting sleeve 8, and the connecting sleeve 8 is sleeved on the first connecting tube 3. Therefore, when we step on the pedal 9 with force, the stepping force on the pedal 9 will decompose an external bending force on the connecting sleeve 8, and then it will be stuck on the first connecting tube 3, so that we can use the pedal 9 to increase the force to insert the device into the soil, and the position of the pedal 9 can be adjusted at will, so that we can continuously adjust the position of the pedal 9 according to the change of the sampling depth, making the device more convenient.

[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
