Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil microorganism sampling device. Background Art

[0002] Soil microorganisms are a general term for all tiny organisms in the soil that are invisible or unclear to the naked eye. Strictly speaking, they should include bacteria, archaea, fungi, viruses, protozoa and microscopic algae. Their individuals are tiny, generally measured in micrometers or millimeter. There are usually hundreds of millions to tens of billions of them in 1 gram of soil. Their types and numbers vary with the soil-forming environment and the depth of the soil layer.

[0003] In the prior art, conventional soil microorganism sampling devices are mostly rotary digging devices with a spiral feeding rod. During use, when it is necessary to collect soil at a certain depth, the surface soil needs to be dug up, which is time-consuming and labor-intensive. It is impossible to perform accurate sampling according to the required soil sampling depth, resulting in errors in the soil microorganism detection structure, which is not conducive to use. The sampled soil needs to be transferred to the sample feeding device, which can easily cause the soil to be contaminated and affect the detection results. Utility Model Content

[0033] During use, insert the drill bit 8 into the soil where sampling is required. Drive the cylinder 10 to rotate through the grip 12. The cylinder 10 drives the round sleeve 1 to rotate through the second locking mechanism 9. The round sleeve 1 drives the drill bit 8 to rotate through the first locking mechanism 7. The drill bit 8 drives the round sleeve 1 to insert downward into the soil. Observe the depth of the round sleeve 1 inserted into the soil according to the scale line 13. When the round sleeve 1 is inserted to the specified depth, stop rotating. The transmission rod 111 in the driving mechanism 11 is sleeved on the rectangular rod 4 through the rectangular groove 114. The handle 113 drives the transmission rod 111 to rotate within the bearing assembly 112, causing the transmission rod 111 to rotate the rectangular rod 4.

At this time, continue to rotate the round sleeve 1. The round sleeve 1 drives the scraping plates 5 to rotate through the adjustment mechanism 3. The scraping plates 5 scrape the soil into the round sleeve 1. After sampling is completed, the driving mechanism 11 drives the adjustment mechanism 3 to reset. The adjustment mechanism 3 drives the scraping plates 5 to reset, causing the scraping plates 5 to close on the side wall of the round sleeve 1, achieving the effect of sealing the round sleeve 1. Then, remove the round sleeve 1 and the drill bit 8 from the soil. Remove the locking bolt 702 in the first locking mechanism 7 from the threaded hole 701 to separate the round sleeve 1 from the drill bit 8.

Sampling is only carried out when the sampling device reaches the specified depth, making the soil sampling position accurate and the test results more reliable. Avoid secondary transfer and contamination of the soil inside the round sleeve 1, ensuring the accuracy of the test structure. For reuse, select a clean round sleeve 1 and connect and fix it to the drill bit 8 and the cylinder 10 respectively through the first locking mechanism 7 and the second locking mechanism 9 to continue soil sampling.

[0034] In summary, the soil microorganism sampling device can reach the specified depth according to the required sampling depth of the soil before sampling, making the soil sampling position accurate and the test results more reliable. At the same time, after sampling is completed, it can be disassembled and used as a sample delivery device to avoid secondary transfer and contamination of the soil, ensuring the accuracy of the test structure.
