Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil sampling technology, and in particular to a soil pollution stratification sampling device. Background Technology
[0002] With the continuous development of industry, the soil in many areas has been polluted to varying degrees. In order to better reflect the pollution status of soil at different depths and to ensure the representativeness and accuracy of sampling results, it is necessary to use a soil sampling drill to sample the polluted soil in layers.
[0003] Currently, existing soil sampling drills have relatively simple structures. When performing stratified sampling, workers need to hold the drill handles with both hands and then slowly rotate and press down on the drill to allow the drill bit to gradually enter the soil. If the workers apply uneven force with their hands or their body posture is incorrect, it will cause uneven axial force on the drill, resulting in the drill tilting. Tilting the drill will make the actual drilling path longer, resulting in a greater measured sampling depth than the true depth when drilling vertically, which will affect the accuracy of the measurement data. To address this issue, we propose a soil pollution stratified sampling device. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil pollution stratification sampling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A soil pollution stratified sampling device includes a column, a sampling drill connected to the bottom end of the column, a connecting cover fitted on the outside of the sampling drill, a slot adapted to the column at the top of the connecting cover, and support plates symmetrically distributed on the lower side of the connecting cover.
[0007] Preferably, the inner wall of the slot is glued with a rubber sleeve, and the other end of the rubber sleeve abuts against the outer wall of the column.
[0008] Preferably, the side of the support plate is glued with a rubber sheet, and the outer side of the rubber sheet is evenly distributed with anti-slip particles.
[0009] Preferably, the connecting cover has U-shaped blocks symmetrically connected to its sides, and the inner wall of the U-shaped blocks is connected to a connecting shaft, with the support plate movably sleeved on the outside of the U-shaped blocks.
[0010] Preferably, a connecting ring is sleeved on the outer side of the connecting cover, and a positioning rod is connected to the lower side of the connecting ring. The top of the support plate is provided with a connecting groove that matches the positioning rod.
[0011] Preferably, the inner side of the connecting ring is symmetrically connected with sliders, the outer wall of the connecting cover is provided with a groove adapted to the slider, and the inner wall of the groove is vertically connected with a connecting spring, the other end of the connecting spring being fixedly connected to the slider.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 A soil pollution stratified sampling device includes a column 1, a sampling drill 2 connected to the bottom of the column 1, and a connecting cover 3 fitted on the outside of the sampling drill 2. A handle is provided at the top of the column 1. The stratified sampling principle of the column 1 and the sampling drill 2 is existing and will not be described in detail here. The top of the connecting cover 3 has a groove adapted to the column 1. The groove allows the column 1 to move downward, so that the sampling drill 2 can drill smoothly into the soil. Support plates 4 are symmetrically distributed on the lower side of the connecting cover 3. The two sets of support plates 4 can be used to position the connecting cover 3. The limiting of the connecting cover 3 can be used to guide the column 1 and the sampling drill 2 vertically, thereby effectively ensuring that the sampling drill 2 samples vertically downward.
[0023] Furthermore, refer to Figure 3 It can be seen that the inner wall of the slot is glued with a rubber sleeve 12, and the other end of the rubber sleeve 12 abuts against the outer wall of the column 1. Through the glued rubber sleeve 12, the outer wall of the column 1 can be effectively prevented from sliding continuously in the slot inside the connecting cover 3, thereby realizing the protection operation of the column 1. Since the inner wall of the rubber sleeve 12 abuts against the column 1, the vertical drilling of the column 1 and the sampling drill 2 can be guaranteed.
[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the support plate 4 has a rubber plate 5 glued to its side, and anti-slip particles are evenly distributed on the outer side of the rubber plate 5. The reliability of the support plate 4 when it is placed on the ground can be guaranteed by setting the rubber plate 5 and multiple sets of anti-slip particles.
[0025] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the side of the connecting cover 3 is symmetrically connected with U-shaped blocks 6, and the inner wall of the U-shaped blocks 6 is connected with a connecting shaft 7. The support plate 4 is movably sleeved on the outside of the U-shaped blocks 6. Through the cooperation of the U-shaped blocks 6 and the connecting shaft 7, the rotation requirements of the support plate 4 can be met. Therefore, the support plate 4 can be folded after use to reduce the floor space occupied by the device.
[0026] Furthermore, refer to Figure 3 It can be seen that a connecting ring 8 is sleeved on the outer side of the connecting cover 3, and a positioning rod 9 is connected to the lower side of the connecting ring 8. A connecting groove that matches the positioning rod 9 is opened at the top of the support plate 4. In use, the folded support plate 4 can be limited by the cooperation of the connecting ring 8 and the positioning rod 9, so as to effectively prevent the support plate 4 from rotating continuously during transportation.
[0027] Furthermore, refer to Figure 3It can be seen that the inner side of the connecting ring 8 is symmetrically connected with the slider 10, the outer wall of the connecting cover 3 is provided with a groove that matches the slider 10, and the inner wall of the groove is vertically connected with the connecting spring 11. The other end of the connecting spring 11 is fixedly connected to the slider 10. Through the cooperation of the slider 10 and the connecting spring 11, the limiting effect on the support plate 4 can be effectively guaranteed.
[0028] Furthermore, refer to Figure 1 and Figure 4 It can be seen that the top of the connecting cover 3 is provided with a threaded groove 13, and the top of the column 1 is connected with a threaded ring 14. In use, through the mutual cooperation of the threaded groove 13 and the threaded ring 14, after use, the top of the connecting cover 3 can be sleeved on the outside of the threaded ring 14, thereby realizing the limiting and fixing of the connecting cover 3, so as to prevent the connecting cover 3 from continuously sliding along the outer wall of the column 1 during transportation and producing abnormal noise.
[0029] Working Principle: When using this utility model, the worker can first place the column 1 to the area where sampling is required, and then rotate the connecting cover 3 to make the threaded groove 13 inside it rotate out from the inside of the threaded ring 14. Then, by pushing down the connecting cover 3, the bottom end of the connecting cover 3 abuts against the ground. Then, the worker can lift the connecting ring 8 to drive the two sets of positioning rods 9 connected to its lower side to move upward under force, thereby releasing the restriction on the support plate 4. Then, the two sets of support plates 4 can rotate along the outer wall of the connecting shaft 7 under gravity and abut against the ground. At this time, the worker can step on the support plate 4 and then rotate the handle at the top of the column 1 to insert the sampling drill 2 into the soil for sampling. After sampling, the worker can pull the sampling drill 2 out of the soil and push the soil inside the sampling drill 2 into the sampling container so that the worker can conduct subsequent testing on the pollution. The above is the complete working principle of this utility model.
