Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a greening planting soil infiltration rate sampling device. Background Art

[0002] Soil infiltration is the dynamic process by which water from rainfall, irrigation, and other sources enters the soil through the mountain surface, where it is transported and stored as soil water under the influence of gravity and matrix potential. It is a crucial link in the mutual conversion and consumption of surface water and groundwater, and a significant factor influencing slope runoff. The soil's ability to infiltrate water, referred to as infiltration capacity, is a quantitative measure of soil infiltration capacity. It refers to the amount of water that passes through a unit area of soil per unit time, maintaining a layer of water at atmospheric pressure above the soil surface. Existing methods for measuring soil infiltration rate in landscaping include manual knife-ring sampling and percolation cylinder sampling. Both methods are complex, with complicated sampling and testing procedures that are prone to unnecessary errors. Both percolation cylinder and knife-ring sampling methods are prone to skew. Relying solely on visual observation can lead to inaccurate angle adjustment, resulting in the collected soil being not perpendicular to the ground. The varying force applied in manual sampling can result in varying degrees of compaction, resulting in poor reproducibility of experimental results. Manual sampling also only allows for the collection of a single sample at a time, making it inefficient.

[0003] There may already be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0007] The sampling structure includes a cylinder, which is inserted into a portal frame. A pressure sensor is installed at the telescopic end of the cylinder.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0025] Example: Through the personnel in this field, all electrical components in this case are connected to their corresponding power supplies through wires, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0026] In order to solve the problems of manual sampling using the ring knife method and the percolation tube method, which are complicated to operate and prone to unnecessary errors, the percolation tube and the ring knife sampling are extremely prone to tilt, and the angle adjustment is inaccurate when relying solely on human visual observation, resulting in the collected soil angle not being perpendicular to the ground, the different forces used in manual soil sampling may cause different densities of the collected soil, resulting in poor repeatability of the experimental results, and manual soil sampling can only collect one sample each time, which is inefficient, this technical solution is designed. The detailed technical solution is as follows;

[0027] See also Figure 1-4 A green planting soil infiltration rate sampling device includes a circular base 1, a control panel 2 is installed on the front wall of the circular base 1, a door frame 3 is installed on the upper wall of the circular base 1, a leveling structure is installed on the side wall of the circular base 1, and a sampling structure is installed on the door frame 3;

[0028] Specifically, the leveling structure includes adjustment components symmetrically arranged in pairs at the four corners of the circular base 1 and a bubble level 4 arranged on the rear end wall of the circular base 1. The adjustment component includes a mounting block 5, on which a bolt 6 is threadedly inserted. An extension rod 7 is installed at one end of the bolt 6, and a support block 18 is movably mounted on the extension rod 7.

[0029] It should be noted that the device is placed on the ground through the support block 18, so that the hollow part of the circular base 1 is aligned with the sampling position. By rotating the bolt 6, one end of the bolt 6 is rotated on the support block 18 through the extension rod 7, so that the bolt 6 is raised and lowered in the mounting block 5 until the bubble in the bubble level 4 is centered. At this time, the sampling structure is perpendicular to the ground, ensuring the accuracy of the adjustment, avoiding the angle of the collected soil not being perpendicular to the ground, and ensuring the repeatability of the experimental results.

[0030] Specifically, the sampling structure includes a cylinder 8, which is inserted into the portal frame 3. A pressure sensor 9 is installed at the telescopic end of the cylinder 8. A horizontal plate 10 is installed on the pressure sensor 9. A plurality of internal threaded sleeves 11 are installed on the lower wall of the horizontal plate 10. A sampling tube is installed on each internal threaded sleeve 11. The sampling tube includes an external threaded neck 12 and a tube body 13. The external threaded neck 12 is installed on the internal threaded sleeve 11 through a thread. The tube body 13 is provided at one end of the external threaded neck 12. A linear displacement sensor 14 is inserted into the portal frame 3. The detection end of the linear displacement sensor 14 is installed on the horizontal plate 10.

[0031] It should be noted that the pressure sensor 9 is provided with a first threshold value. Subsequently, the operator operates the control panel 2 to extend the cylinder 8, which drives the components thereon to descend until the lower end of the tube body 13 touches the ground. The cylinder 8 continues to extend, so that the pressure value detected by the pressure sensor 9 is always maintained at the first threshold value. The soil enters the tube body 13, ensuring that the pressure of different soil sampling tests is the same, thereby avoiding errors.

[0032] The operator sets the sampling depth by operating the control panel 2. As the horizontal plate 10 descends, the detection end of the linear displacement sensor 14 moves along with the descent of the horizontal plate 10. When the pressure value detected by the pressure sensor 9 reaches a first threshold, the linear displacement sensor 14 starts counting. When the value reaches the set sampling depth, the cylinder 8 contracts, causing the pipe body 13 to move above the ground.

[0033] Multiple sampling tubes are provided, and multiple soil samples can be taken in one sampling process, which improves the sampling efficiency. When the sampling is completed, the tube body 13 is rotated, and the tube body 13 drives the external thread neck 12 to disengage the internal thread sleeve 11, and the soil sample in the tube body 13 can be collected;

[0034] As a preferred embodiment, further, a bottom guide rod 15 is installed on the upper wall of the mounting block 5, and the bottom guide rod 15 is movably inserted on the mounting block 5 for guiding and limiting the mounting block 5;

[0035] As a preferred embodiment, further, a top guide rod 16 is installed on the upper wall of the horizontal plate 10, and the top guide rod 16 is movably inserted into the door frame 3 for guiding and supporting the horizontal plate 10;

[0036] As a preferred embodiment, further, the lower end of the tube body 13 is a serrated structure, which facilitates the insertion of the tube body 13 into the soil;

[0037] As a preferred embodiment, further, a vent hole 17 is provided at the upper end of the side wall of the tube body 13 to balance the air pressure in the tube body 13 and facilitate the entry of soil into the tube body 13;

[0038] As a preference, further, the external threaded neck 12 and the tube body 13 are an integral structure.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
