Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to a rapid soil sampler. Background Technology

[0002] Environmental monitoring refers to determining the value of environmental quality factors, and then determining environmental conditions and their trends. Currently, most environmental monitoring methods use soil sampling and testing. Soil sample collection and pretreatment are crucial steps in soil science research and environmental monitoring.

[0003] Existing samplers require inserting the device into the soil, allowing the soil to enter the sampling hole, and then pulling the device out. During operation, it is often difficult to accurately control the sampling depth, resulting in inaccurate sampling results when sampling soil at different depths. Furthermore, only a single sample can be collected at a time. Therefore, this application proposes a rapid soil sampler. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that soil is difficult to extract from the sampling hole, and to propose a rapid soil sample collector.

[0005] The technical solution of this utility model: a rapid soil sample collector, including a mounting plate, and further comprising:

[0006] A sampling rod is fixedly mounted on a mounting plate. The sampling rod has multiple sampling slots arranged at equal intervals. A sampling block is slidably installed in the sampling slot. The sampling block has a sampling hole. A conical block is fixedly installed at the bottom of the sampling rod. The sampling rod is equipped with a guide mechanism to drive the sampling block to take samples.

[0007] Optionally, the guiding mechanism includes a connecting plate fixedly mounted on a mounting plate, a threaded rod threadedly mounted on the connecting plate, a fixed block slidably mounted inside the sampling rod, the fixed block being rotatably connected to the threaded rod, a track block fixedly mounted inside the sampling rod, a slider symmetrically slidably mounted inside the track block, a guide plate hinged to the slider, one end of the guide plate being hinged to the fixed block, a fixed plate fixedly mounted to one end of the slider, the fixed plate being slidably connected to the track block, the fixed plate being fixedly connected to the sampling block, and a sealing mechanism provided on the sampling rod for sealing when the sampling groove is inserted into the soil.

[0008] Optionally, the sealing mechanism includes a sleeve rotatably mounted on the sampling rod, the sleeve having multiple through holes at equal intervals, the through holes coinciding with the sampling groove, and an installation rod fixedly mounted on the sleeve.

[0009] Optionally, a groove is provided inside the sampling rod, and a connecting rod is fixedly installed on one side of the fixing block, with the connecting rod located inside the groove.

[0010] Optionally, the track block is provided with a guide groove, and a protrusion is fixedly installed on one side of the slider, the protrusion being located in the guide groove.

[0011] Optionally, a rotating block is fixedly installed at one end of the threaded rod, and an anti-slip block is provided on the rotating block.

[0012] Optionally, a connecting column is fixedly installed on the mounting plate, and the connecting column is fixedly connected to the connecting plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. By rotating the threaded rod to move the fixed block downward, the guide plate is squeezed to both sides. The guide plate moves the fixed plate on one side of the slider, and the sampling block on the fixed plate is pushed out of the sampling groove. The soil is squeezed into the sampling hole. The reverse threaded rod moves the sampling block into the sampling groove, which realizes accurate sampling of soil at different depths and improves the diversity of samples.

[0015] 2. By setting a rotating sleeve on the sampling rod, the sampling groove can be sealed before the soil is inserted and pulled out, so as to prevent soil from entering the sampling groove during the process of inserting and pulling out the soil, which would cause inaccurate sampling.

[0016] This invention enables soil sampling at different depths, improving sampling accuracy, convenience, and sampling diversity. Attached Figure Description

[0029] Example

[0030] like Figure 1-2 As shown, the present invention proposes a rapid soil sample collector, which includes a mounting plate 1 and a sampling rod 2. The sampling rod 2 is fixedly mounted on the mounting plate 1. The sampling rod 2 has multiple sampling slots 22 arranged at equal intervals. A sampling block 8 is slidably installed in the sampling slots 22. The sampling block 8 has a sampling hole 7. A conical block 6 is fixedly installed at the bottom of the sampling rod 2 to facilitate the insertion of the sampling rod 2 into the soil. The sampling rod 2 is provided with a guide mechanism to drive the sampling block 8 to take samples.

[0031] like Figure 2-3 As shown, this embodiment also includes a guiding mechanism, which includes a connecting plate 3 fixedly mounted on the mounting plate 1. A threaded rod 4 is threadedly mounted on the connecting plate 3. A fixing block 9 is slidably mounted inside the sampling rod 2, and the fixing block 9 is rotatably connected to the threaded rod 4. A track block 14 is fixedly mounted inside the sampling rod 2, and a slider 15 is symmetrically slidably mounted inside the track block 14. A guide plate 10 is hinged to the slider 15, and one end of the guide plate 10 is hinged to the fixing block 9. A fixing plate 12 is fixedly mounted to one end of the slider 15, and the fixing plate 12 is slidably connected to the track block 14. The fixing plate 12 is fixedly connected to the sampling block 8. When the sampling rod 2 is inserted into the soil and the threaded rod 4 is rotated, the threaded rod... 4 is threadedly connected to the connecting plate 3. The threaded rod 4 moves downward continuously. One end of the threaded rod 4 drives the fixed block 9 to move downward. The fixed block 9 presses against the guide plate 10. Since the guide plate 10 is hinged to the slider 15, the guide plate 10 drives the slider 15 to move to both sides. The slider 15 drives the fixed plate 12 to move. The sampling block 8 on the fixed plate 12 moves out of the sampling groove 22. The sampling block 8 comes into contact with the soil and is pressed. The soil enters the sampling hole 7. The threaded rod 4 is reversed. At this time, the fixed plate 12 moves the sampling block 8 back into the sampling groove 22 to complete the sampling of soil at different depths. The sampling rod 2 is equipped with a sealing mechanism to seal the sampling groove 22 when it is inserted into the soil.

[0032] like Figure 4-5As shown, this embodiment also includes a sealing mechanism, which includes a sleeve 18 rotatably mounted on the sampling rod 2. The sleeve 18 has multiple through holes 20 evenly spaced on it, and the through holes 20 coincide with the sampling groove 22. An installation rod 16 is fixedly mounted on the sleeve 18. Before inserting and removing the soil, the sleeve 18 is rotated to make the through holes on the sleeve 18 misaligned with the sampling groove 22. The inner wall of the sleeve 18 seals the sampling groove 22, preventing soil of different depths from entering the sampling groove 22 during insertion and removal, and preventing soil of different depths from remaining in the same sampling groove 22, thus improving sampling accuracy. When sampling, the sleeve 18 is simply rotated back to its original position, at which point the through holes 20 coincide with the sampling groove 22, and the sampling block 8 can be moved out of the sampling groove 22 for sampling.

[0033] like Figure 1-3 As shown, a sliding groove 11 is provided inside the sampling rod 2, a connecting rod 13 is fixedly installed on one side of the fixing block 9, the connecting rod 13 is located in the sliding groove 11, a guide groove 17 is provided on the track block 14, a protrusion 19 is fixedly installed on one side of the slider 15, the protrusion 19 is located in the guide groove 17, a rotating block 5 is fixedly installed on one end of the threaded rod 4, an anti-slip block is provided on the rotating block 5, and a connecting column 21 is fixedly installed on the mounting plate 1, the connecting column 21 is fixedly connected to the connecting plate 3.

[0034] Working principle: Before inserting into the soil, rotate the sleeve 18 to misalign the through hole on the sleeve 18 with the sampling groove 22, and the inner wall of the sleeve 18 seals the sampling groove 22. After insertion, rotate the sleeve 18 back to its original position. At this time, the through hole 20 coincides with the sampling groove 22. Rotate the threaded rod 4. Since the threaded rod 4 is threadedly connected to the connecting plate 3, the threaded rod 4 moves downward continuously. One end of the threaded rod 4 drives the fixing block 9 to move downward. The fixing block 9 presses against the guide plate 10. Because the guide plate 10 and the sliding plate 10 are connected, the sliding plate 10 is pressed against the guide plate 10. The hinged block 15 causes the guide plate 10 to move the slider 15 to both sides. The slider 15 moves the fixed plate 12, and the sampling block 8 on the fixed plate 12 moves out of the sampling slot 22. The sampling block 8 comes into contact with and is squeezed by the soil, and the soil enters the sampling hole 7. The threaded rod 4 is reversed. At this time, the fixed plate 12 moves the sampling block 8 back into the sampling slot 22 to complete the sampling of soil at different depths. This realizes the sampling of soil at different depths, improves sampling accuracy, improves convenience, and has high sampling diversity.

[0035] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
