Description

Technical Field

[0001] This utility model relates to the technical field of soil sampling devices, specifically a sampling device for detecting low-cadmium rice in paddy fields. Background Technology

[0002] Soil sampling refers to the process of collecting soil using sampling devices. The purpose of soil sampling is to understand the properties, composition, and environmental conditions of the soil in order to carry out soil improvement, fertilization, crop planting, and environmental protection.

[0003] Some existing soil sampling devices cannot accurately sample soil at a predetermined depth. If it is necessary to sample soil at a predetermined depth, the upper layer of soil must be dug out before sampling. This method may cause the upper layer of soil to mix into the soil at the predetermined depth, resulting in a messy sample. It also cannot guarantee the integrity of the soil surface and increases the workload of the staff. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a sampling device for rice paddy testing in low-cadmium rice cultivation. This sampling device utilizes the rotation of the sampling component to penetrate deep into the soil, which facilitates sampling operations at a predetermined depth. In conjunction with the setting of the lifting plate, the lifting plate is always in contact with the ground during sampling. When the sampling component penetrates deep into the soil, the lifting plate rises by the same height, which makes it easy for staff to observe the depth of penetration and thus determine whether it corresponds to the predetermined depth. Finally, through the liftable placement component, the soil at the predetermined depth can be easily inserted to achieve accurate soil sampling.

[0005] This invention is achieved by constructing a sampling device for detecting low-cadmium rice in paddy fields, including a first support plate with a rotatable sampling component running through its center.

[0006] The second support plate is connected to the first support plate in parallel via a connecting rod.

[0007] A lifting plate is slidably connected above the second lifting plate and corresponds to the end position of the sampling component;

[0008] The component is positioned above the second support plate and can be raised and lowered.

[0009] The sampling components all penetrate the second support plate and the lifting plate. When the placement component is lowered, it contacts the lifting plate and places the sample.

[0010] Preferably, the sampling assembly includes a drive motor and a sampling rod that rotates with the drive motor. The drive motor is fixed above the first support plate. One end of the sampling rod is connected to the drive motor, and the other end passes through the first support plate, the second support plate, and the lifting plate. A spiral is provided on the outer end of the sampling rod.

[0011] Preferably, both the second support plate and the lifting plate have through holes for the sampling component to pass through. A through hole is provided outside the through hole of the second lifting plate. The lifting plate is kept sliding by a slide rod passing through the through hole. A limit head is also movably installed at the end of the slide rod.

[0012] Preferably, the slide bar is also marked with scale lines.

[0013] Preferably, the placement assembly includes a sampling cylinder, which is disposed between the inner wall of the through hole of the second support plate and the sampling assembly and maintains linear sliding.

[0014] The mounting rod is set on the outside of the sampling tube and one end is fixed to the sampling tube, while the other end slides linearly through the second support plate.

[0015] Place the container, attach it to the outside of the sampling tube, and movably connect it to the end of the mounting rod via a movable connector;

[0016] The elastic element, located on the outside of the mounting rod, is used to push the sampling tube and position the container away from the lifting plate.

[0017] Preferably, a boss is provided on the outer side of one end of the sampling tube, and the mounting rod is fixed on the boss. A discharge hole is provided on the outer side of the other end of the sampling tube. When the placement container is installed on the outer side of the sampling tube, the discharge hole is offset from the placement container.

[0018] Preferably, the end of the mounting rod away from the boss is provided with an external thread, and the container is fixed by being fitted onto the external thread of the mounting rod through the mounting rod via a movable connector.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This sampling device uses a rotating sampling component to enter the soil, which is then raised and lowered synchronously with a lifting plate that is in real time attached to the ground. This transforms the soil sampling depth into a visible displacement, achieving precise positioning and sampling of soil at a predetermined depth compared to traditional sampling methods. This provides reliable samples for scientific research projects and environmental monitoring that have stringent depth requirements, such as soil profile analysis.

[0021] Meanwhile, the rotating soil-entry design significantly reduces soil resistance, thereby reducing the manpower and time costs of sampling operations; the lifting platform intuitively displays the sampling depth, eliminating the need for additional measuring tools, allowing operators to quickly determine whether the predetermined depth has been reached, greatly improving sampling efficiency and simplifying the operation process.

[0022] By precisely connecting the liftable placement component with the sampling tube outlet, soil samples from different depths are prevented from mixing within the placement component during transfer, thus ensuring the purity and integrity of soil samples from a single depth and effectively improving the reliability and accuracy of soil testing and analysis data.

Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0031] As described in the background section, some existing soil sampling devices are unable to accurately sample soil at a specified depth.

[0032] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 5 This utility model provides a sampling device for detecting low-cadmium rice in paddy fields, including a first support plate 1, with a rotatable sampling component running through the center.

[0033] The second support plate 4 is connected to the first support plate 1 in parallel via the connecting rod 3;

[0034] The lifting plate 5 is slidably connected above the second lifting plate 4 and corresponds to the end position of the sampling component;

[0035] The component is positioned above the second support plate 4 and can be raised and lowered.

[0036] The sampling components all penetrate the second support plate 4 and the lifting plate 5. When the placement component is lowered, it contacts the lifting plate 5 and places the sample.

[0037] In this embodiment, the sampling assembly includes a drive motor 2 and a sampling rod 6 that rotates with the drive motor 2. The drive motor 2 is fixed above the first support plate 1. One end of the sampling rod 6 is connected to the drive motor 2, and the other end passes through the first support plate 1, the second support plate 4, and the lifting plate 4 respectively. A spiral is provided on the outer end of the sampling rod 6.

[0038] As described above, the spiral at the outer end of the sampling rod can not only be screwed into the soil, but also transport the upper soil layer upwards, facilitating the transport and sampling of deep soil layers.

[0039] In this embodiment, both the second support plate 4 and the lifting plate 5 are provided with through holes for the sampling component to pass through. A through hole is provided outside the through hole of the second lifting plate 4. The lifting plate 5 is kept sliding by a slide rod 7 passing through the through hole. A limit head 8 is also movably installed at the end of the slide rod 7.

[0040] In this embodiment, the slide bar 7 is also marked with scale lines. By setting the scale lines, it is convenient for staff to observe the depth when operating the device to take samples, so as to achieve accurate sampling of soil at a specified depth.

[0041] In this embodiment, the placement component includes a sampling cylinder 9, which is disposed between the inner wall of the through hole of the second support plate 4 and the sampling component and maintains linear sliding.

[0042] The mounting rod 10 is set on the outside of the sampling cylinder 9 and one end is fixed to the sampling cylinder 9, while the other end passes through the second support plate 4 and slides in a straight line.

[0043] The container 12 is placed on the outside of the sampling tube 9 and is movably connected to the end of the mounting rod 10 via the movable connector 13;

[0044] The elastic element 11 is provided on the outside of the mounting rod 10 to push the sampling cylinder 9 and the container 12 away from the lifting plate 5.

[0045] In this embodiment, a boss 901 is provided on the outer side of one end of the sampling cylinder 9, and the mounting rod 9 is fixed on the boss 901. A discharge hole 902 is provided on the outer side of the other end of the sampling cylinder 9. When the placement container 12 is installed on the outer side of the sampling cylinder 9, the discharge hole 902 is offset from the placement container 12.

[0046] In this embodiment, the end of the mounting rod 10 away from the boss 901 is provided with an external thread, and the placement container 12 passes through the mounting rod 10 and is fixed by the movable connector 13 sleeved on the external thread of the mounting rod 10.

[0047] Furthermore, the placement container has an arc-shaped structure, which makes it easy to fit against the outside of the sampling tube and also easy to remove. It is preferred to use two placement containers that are correspondingly attached to the outside of the sampling tube.

[0048] As described above, the movable connection between the container and the mounting rod, as well as the shape of the container, facilitates placement and retrieval, thereby enabling soil sampling and subsequent testing.

[0049] In use, the sampling device first determines the required soil depth, then moves the device to the soil to be sampled, keeping the lifting plate 5 in contact with the ground (due to gravity, the lifting plate is lowered to its lowest point, aligning with the end of the sampling rod 6). Then, the drive motor 2 starts, causing the sampling rod 6 to rotate. Because the sampling rod 6 has a spiral on its outer side, it can penetrate deep into the soil during rotation, simultaneously conveying the soil upwards until it falls onto the lifting plate 5. As the sampling rod 6 penetrates deeper into the soil, the lifting plate 5 remains in contact with the soil surface, thus causing it to rise and fall under the action of reaction force. The plate 5 moves towards the second support plate 4, which pushes the slide rod 7 to slide. The staff can observe the scale on the slide rod 7 to determine the soil depth. When the appropriate depth is reached, the staff first cleans the soil on the lifting plate 5, and then presses down the sampling cylinder 9, which drives the placement container 12 to descend until the end of the sampling cylinder 9 contacts the lifting plate 5. At this time, the sampling rod 6 rotates, and the soil is conveyed by the screw, passing through the through hole of the lifting plate 5 and the sampling cylinder 9, and then discharged from the discharge hole 902 and falls into the placement container 12, thus realizing the accurate sampling of soil at a specified depth.

[0050] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
