Description

Technical Field

[0001] The utility model relates to the technical field of soil samplers, in particular to a sampler for soil monitoring. Background Art

[0002] With the increasing awareness of environmental protection and the need for agricultural production, soil monitoring has become an important task. Soil monitoring can not only understand the soil quality status, but also provide a scientific basis for agricultural production. In the process of soil monitoring, sampling is one of the key links. Traditional soil sampling methods are mostly manual sampling, which has problems such as uneven sampling and difficult to control sampling depth. It is labor-intensive and has low sampling efficiency. In addition, most samplers still have problems such as inaccurate positioning and inflexible sampling mechanisms during the sampling process, resulting in inaccurate sampling results and unable to meet the accuracy requirements of soil monitoring.

[0008] Preferably, a magnetic groove is provided on the inner wall at the top of the slide groove on the outer surface of the sampling tube. The magnetic groove cooperates with the magnetic pin to further enhance the stability of the slider in the slide groove and ensure that the slider does not move or fall off during the sampling process.

[0009] Preferably, the outer surfaces of both ends of the handle are wrapped with rubber rings, which can increase the friction between the handle and the operator's hand, making the operation more stable and preventing accidental injuries due to slipping during use.

[0010] Preferably, a connecting ring is installed on the outer surface of the top end of the first connecting rod, and a thread is provided on the inner wall of the connecting ring, so that the connecting ring serves as a limiting connection for the connecting plate.

[0011] Preferably, a connecting ring is installed on the top outer surface of the connecting plate, and a thread is provided on the outer surface of the connecting ring. The connecting plate is slid to the bottom end of the handle, and then the connecting ring is rotated so that the connecting ring and the connecting ring are engaged with each other, thereby maintaining the stability of the connecting plate when carried.

[0012] Preferably, multiple groups of positioning rings are fixedly installed on the outer surfaces of the multiple groups of positioning rods, and the positioning rings can increase the insertion depth of the positioning rods in the soil and improve the positioning stability of the sampler.

[0013] It can be seen from the above technical solutions that this application has the following beneficial effects:

[0014] 1. The utility model realizes accurate positioning of the sampler through multiple sets of positioning rods fixedly installed on the external board, solving the problem of inaccurate positioning of the traditional sampling method. The insertion of the positioning rod can ensure that the sampler is stably fixed at the predetermined sampling position, thereby greatly improving the accuracy of the sampling point and providing more reliable data support for subsequent soil monitoring and analysis.

[0015] 2. The utility model utilizes a sampling mechanism composed of a slider and a scraper. By pulling the slider, the scraper slides along the inner wall of the sampling tube, thereby easily pushing the soil sample out of the sampling tube. This design not only improves the sampling efficiency, but also ensures the uniformity and integrity of the soil sample, avoiding the problems of uneven sampling or sample damage that may occur in traditional methods.

[0025] Furthermore, a magnetic pin 916 is fixedly installed on the top outer surface of the slider 914. The addition of the magnetic pin 916 makes the positioning of the slider 914 in the slide groove more stable, preventing the slider 914 from accidentally sliding during the sampling or pushing out of the soil sample, thereby affecting the sampling effect.

[0026] Furthermore, a magnetic groove 917 is provided on the inner wall at the top of the slide groove on the outer surface of the sampling tube 911. The magnetic groove 917 cooperates with the magnetic pin 916 to further enhance the stability of the slider 914 in the slide groove, ensuring that the slider 914 does not move or fall off during the sampling process.

[0027] Furthermore, both ends of the outer surface of the handle 1 are wrapped with rubber rings 2, which can increase the friction between the handle 1 and the operator's hand, making the operation more stable and preventing accidental injuries caused by slipping during use.

[0028] Furthermore, a connecting ring 5 is installed on the outer surface of the top end of the first connecting rod 3 , and a thread is provided on the inner wall of the connecting ring 5 . The connecting ring 5 serves as a limiting connection for the connecting plate 7 .

[0029] Furthermore, a connecting ring 6 is installed on the outer surface of the top end of the connecting plate 7, and a thread is provided on the outer surface of the connecting ring 6. The connecting plate 7 is slid to the bottom end of the handle 1, and then the connecting ring 6 is rotated so that the connecting ring 6 and the connecting ring 5 are engaged with each other, thereby maintaining the stability of the connecting plate 7 when being carried.

[0030] Furthermore, multiple sets of positioning rings 912 are fixedly installed on the outer surfaces of the multiple sets of positioning rods 9. The positioning rings 912 can increase the insertion depth of the positioning rods 9 in the soil and improve the positioning stability of the sampler.

These positioning rods 9 can be inserted into the soil as needed to fix the position of the sampler and ensure the accuracy of the sampling point. When the positioning is completed, the operator can hold the handle 1 and rotate and adjust the first connecting rod 3 and the second connecting rod 4 so that the sampling tube 911 can penetrate to the predetermined sampling depth. Since the second connecting rod 4 is connected to the sampling tube 911, the sampling depth of the sampling tube 911 can be conveniently controlled by adjusting the angle and length of the second connecting rod 4. After the sampling is completed, the operator can pull the slider 914 to move in the slide groove through the handle 913. The movement of the slider 914 drives the scraper 915 to slide along the inner wall of the sampling tube 911, thereby pushing the soil sample out of the sampling tube 911. The design of the scraper 915 can ensure the uniformity and integrity of the soil sample and improve the sampling quality.
