The angular cutting edge 306, with measuring structures 5 on the inner ring 1 and outer ring 2, allows the inner ring 1 and outer ring 2 to be pressed vertically into the grass soil using the sharp structure of the cutting edge 306. When pressing the inner ring 1 and outer ring 2, the protective cover 301 can be fastened to the top of the inner ring 1 and outer ring 2. The inner ring 1 and outer ring 2 are then pressed down by the protective cover 301 and the picking structure 4 on the protective cover 301. After the inner ring 1 and outer ring 2 are inserted and stabilized, the protective cover 301 can be removed and placed on an open ground. When it is necessary to transfer the inner ring 1 and outer ring 2, the bottom ends of the inner ring 1 and 2 can be inserted into the first annular groove 302 and the second annular groove 303, thereby preventing the cutting edge 306 from accidentally injuring the operator.

[0026] As a technical optimization of this utility model, the ring wall cross-section of the insert ring 304 is L-shaped, and the ring wall cross-section of the mounting ring 305 is L-shaped. When installing the cutting edge 306, the insert ring 304 needs to be inserted into the bottom end of the inner ring 1 or the outer ring 2 first, then the mounting ring 305 with an L-shaped cross-section is welded first, and finally the cutting edge 306 is welded to the bottom end of the insert ring 304. The insert ring 304 can rotate, and the cross-sectional design of the mounting ring 305 improves the stability of the insertion of the cutting edge 306.

[0027] As a technical optimization of this utility model, the measuring structure 5 includes a support bar 501. The inner ring 1 and outer ring 2 are provided with a support bar 501 with a cross-section of "+". Two sets of fixing blocks 502 are fixedly connected to the support bar 501.

A positioning post 505 is fixedly connected to the mounting block 504. The support bar 501 is provided with a positioning hole 506. The positioning post 505 is inserted into the positioning hole 506. After the inner ring 1 and the outer ring 2 are fully inserted into the soil, the support bar 501 is placed at the top of the inner ring 1 and the outer ring 2, so that the positioning post 505 is inserted into the positioning hole 506 on the support bar 501. The fixing block 502 is inserted into the inner ring 1, completing the positioning and installation of the support bar 501. The float rod 503 passes through the limiting ring 8 and its bottom end is placed inside the inner ring 1.

[0028] As a technical optimization of this utility model, the support bar 501 is provided with a water injection structure 6. The water injection structure 6 includes a water injection cylinder 601. Two water injection cylinders 601 are fixedly connected to the support bar 501. A drain valve 602 is fixedly connected to each water injection cylinder 601. One drain valve 602 is located between the inner ring 1 and the outer ring 2, and the other drain valve 602 is located inside the inner ring 1. When the drain valve 602 of the water injection cylinder 601 is opened, one drain valve 602 injects water into the inner ring 1, and the other injects water between the inner and outer rings. The water level in the inner ring 1 is raised until the soil reaches saturation. During the water injection process, the rise of the float 503 is observed. The float 503 rises with the water level. After the soil is saturated, the drain valve 602 is closed and the time is recorded. As water gradually seeps into the soil, the water level in the inner ring 1 drops, and the float 503 also drops. Based on the relative position changes of the scale line 10 on the float 503 and the marker block 9, the water level drop values ​​at different time points are read. After recording the data multiple times, the soil moisture infiltration rate of the grassland is calculated using relevant formulas.

[0029] As a technical optimization of this utility model, the protective cover 301 is provided with a picking structure 4, which includes a fixed base 401.

A connecting block 403 is fixedly connected to the rotating shaft 402. A handle 404 is fixedly connected to the connecting block 403. By holding the handle 404 and rotating the rotating shaft 402, the handle 404 is rotated to a suitable angle, and the inner ring 1 and the outer ring 2 are transferred to the cleaned area.

[0030] When using this invention, first select a suitable grassy measurement location, clear away debris and weeds in the area to make the ground as flat as possible for easy installation of the subsequent device. Hold the handle 404 and rotate the shaft 402 to rotate the handle 404 to a suitable angle, then transfer the inner ring 1 and outer ring 2 to the cleared area. Using the sharp structure of the blade 306, press the inner ring 1 and outer ring 2 vertically into the grass soil. When pressing the inner ring 1 and outer ring 2 in, the protective cover 301 can be fastened to the top of the inner ring 1 and outer ring 2. Press down the inner ring 1 and outer ring 2 using the protective cover 301 and the lifting structure 4 on the protective cover 301, and then insert the inner ring 1 and outer ring 2 stably. After that, the protective cover 301 can be removed and placed on an open ground nearby. When it needs to be transferred... When inner ring 1 and outer ring 2 are connected, the bottom ends of inner ring 1 and 2 can be inserted into the first annular groove 302 and the second annular groove 303, thereby avoiding accidental injury to the operator by the cutting foot 306. When installing the cutting foot 306, the insert ring 304 needs to be inserted into the bottom end of inner ring 1 or outer ring 2 first, then the mounting ring 305 with an L-shaped cross section is welded first, and finally the cutting foot 306 is welded to the bottom end of the insert ring 304. The insert ring 304 can rotate, and the cross section design of the mounting ring 305 improves the stability of the insertion of the cutting foot 306.

[0031] After the inner ring 1 and outer ring 2 are fully inserted into the soil, the support bar 501 is placed at the top of the inner ring 1 and outer ring 2, so that the positioning post 505 is inserted into the positioning hole 506 on the support bar 501, and the fixing block 502 is inserted into the inner ring 1, completing the positioning and installation of the support bar 501. The float rod 503 passes through the limiting ring 8 and its bottom end is placed inside the inner ring 1. The limiting ring 8 is fixed to the support bar 501 by four support rods 7. The scale block 9 cooperates with the scale line 10 on the float rod 503 to accurately measure water level changes. At the same time, the ball bearing 12 on the fixing sleeve 11 is in rolling connection with the float rod 503 to reduce the friction when the float rod 503 slides. Open the water injection cylinder 601. Water valve 602 is used to inject water into the inner ring 1, and another water valve injects water between the inner and outer rings, causing the water level in the inner ring 1 to rise until the soil is saturated. During the water injection process, the rise of the float rod 503 is observed. The float rod 503 rises with the water level. After the soil is saturated, the water valve 602 is closed and the time is recorded. As water gradually seeps into the soil, the water level in the inner ring 1 drops, and the float rod 503 also drops. Based on the relative position change of the scale line 10 on the float rod 503 and the marker block 9, the water level drop value at different time points is read. After recording the data multiple times, the infiltration rate of grassland soil water is calculated using relevant formulas.
