Description

Technical Field

[0001] The utility model relates to the technical field of environmental soil collection, in particular to a soil collection device used for environmental detection. Background Art

[0002] Soil collection is a fundamental and critical activity in environmental science and agricultural research, which involves collecting soil samples from different geographical locations for quality analysis, contamination assessment, and detection of soil composition. Traditional soil collection methods often rely on hand tools such as shovels and drilling equipment, which are not only labor-intensive but also inefficient, especially when soil samples need to be obtained from multiple different depths and locations.

[0003] Although existing mechanized soil collection devices have improved collection efficiency, they still have many inconveniences, such as complex equipment, cumbersome operation, difficult maintenance and high cost. In addition, these devices often cause significant disturbance to the soil, which may affect the original state of the sample and thus affect the accuracy of subsequent analysis.

[0004] Therefore, it is necessary to develop a soil collection device with a simple structure, easy operation and maintenance, and little soil disturbance to improve the efficiency and accuracy of environmental monitoring and agricultural research. This new soil collection device should be able to adapt to different soil types and collection environments, while ensuring that the soil samples during the collection process are not contaminated, ensuring the reliability and validity of the obtained data.

[0005] In addition, the soil collection equipment currently on the market often requires a lot of manpower or uses complex mechanical systems in operation, which not only increases the difficulty of operation but also increases the cost. Therefore, designing a device that can efficiently complete soil collection while maintaining ease of operation and cost-effectiveness is an important direction for the development of current soil collection technology.

[0006] The soil collection device provided by the utility model aims to solve the above-mentioned problems by simplifying the mechanical structure and optimizing the operation process, and provides a more efficient, stable and user-friendly soil collection solution to meet the needs of modern environmental monitoring and agricultural research.

[0026] In one embodiment, the operating bracket 2 includes a U-shaped frame 101, a threaded block 102, and a side plate 103.

At this time, the first operating handle 3 is shaken left and right to make the soil fall into the soil collecting chamber 205 from the sampling port 206, and then the second operating handle 8 is rotated in the opposite direction to make the threaded rod 7 drive the sliding guide column 202 to slide upward, and the sliding guide column 202 drives the collecting tube 201 to slide upward until the collecting tube 201 is completely retracted into the sliding groove mouth 204, and finally the first operating handle 3 is rotated to remove the drilling guide rod 1 from the ground, and then the second operating handle 8 is rotated to slide the collecting tube 201 out of the sliding groove mouth 204, and the collected soil can be taken out through the sampling port 206.

[0030] The working principle of the utility model is as follows: first, the operator sets up the operating bracket 2 on the ground, ensures that the side plate 103 of the U-shaped frame 101 is flat on the ground, and steps on the side plate 103 to fix and stabilize the position of the entire device. Then, the operator operates the drilling guide rod 1 to rotate through the first operating handle 3, and the upper end of the drilling guide rod 1 is threadedly connected with the threaded hole of the operating bracket 2 through the external thread 5, so that the drilling guide rod 1 is stabilized during the operation process;

[0031] The lower end of the drilling guide rod 1 is equipped with a cone head 6 and a collector. The cone head 6 helps the drilling guide rod 1 to drill into the ground more easily. The rotation and downward pressure of the drilling guide rod 1 are controlled by the first operating handle 3, and the design of the spiral piece 4 makes the penetration and screwing efficiency of the drilling guide rod 1 in the soil higher, and also helps to push the soil upward, which is convenient for the soil collection action of the collector;

[0032] When the drilling guide rod 1 drills into a proper depth, the operator rotates the second operating handle 8, which is connected to the slide guide column 202 on the collector through the threaded rod 7. The second operating handle 8 is rotated to drive the slide guide column 202 to move downward or upward in the slide guide groove 207 through the rotation of the threaded rod 7, thereby controlling the movement of the collection tube 201. The collection tube 201 extends outward from the slide groove opening 204 to explore the surface or return to the slide groove opening 204. A sampling port 206 is provided at the lower end of the collection tube 201. By shaking the first operating handle 3 left and right, the soil can fall through the sampling port 206 into the soil collection cavity 205;

[0033] After the soil collection is completed, the second operating handle 8 is operated in the reverse direction to move the collection tube 201 upward and completely retract it back into the chute opening 204. Then, the operator uses the first operating handle 3 again to lift the drilling guide rod 1 from the ground, and slides the collection tube 201 out of the chute opening 204 through the second operating handle 8, and takes out the collected soil through the sampling port 206 for analysis;

[0034] In addition, during the entire operation process, the brush plates 106 located on both sides of the operating bracket 2 automatically remove the dirt and residue on the surface of the drilling guide rod 1 during the drilling process, thereby keeping the equipment clean and operating efficiently. The design of these brush plates 106 not only cleans hard or sticky soil, but also can adapt to the cleaning needs of soft soil, ensuring the cleaning and maintenance of the equipment, extending its service life, and maintaining efficient working performance.
