[0002] Agricultural field measurement is the quantitative or qualitative measurement and recording of crop growth indicators, environmental conditions, and experimental treatment effects in a field setting during agricultural experiments. It is the core link in obtaining experimental data and analyzing experimental results.

[0003] Traditional agricultural experimental field measuring tools are mostly used by attaching one end of the measuring tool to the end of the agricultural experimental field inspection point, and then pulling the measuring tape to assist in the measurement of the agricultural experimental field. However, when using traditional devices, it is difficult to ensure that one end of the measuring tool is stably limited to a fixed area, which causes the measuring tool to easily shift position during measurement, thus affecting the measurement results. Utility Model Content

[0007] As a preferred embodiment of this utility model, a rotating rod is rotatably connected to the bottom of the inner wall of the fixed cylinder, and an adjusting gear is fixedly mounted on the top of the rotating rod, a connecting rod is mounted on the top of the adjusting gear, and an adjusting plate is fixedly mounted on the top of the connecting rod.

[0008] As a preferred embodiment of this utility model, a tension spring is fixedly connected to the side of the inner wall of the fixed cylinder, and the end of the tension spring away from the inner wall of the fixed cylinder is fixedly connected to the outer edge of the rotating rod. A toothed plate is slidably connected to the inner wall of the fixed cylinder, and the protruding teeth of the toothed plate mesh with the protruding teeth of the adjusting gear. A positioning protrusion is fixedly mounted on the side of the toothed plate, and the outer edge of the positioning protrusion is slidably sleeved with the inner wall of the fixed cylinder and the inner wall of the collar.

[0009] As a preferred technical solution of this utility model, a second spring is fixedly connected to the top of the inner wall of the hanging frame, and a positioning rod is fixedly connected to the bottom of the second spring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This agricultural experimental field measuring tool, through the combined use of an adjusting rod and a limiting plate, inserts the cone into the ground. The adjusting rod drives the outer edge of the limiting plate through the inner wall of the sliding groove to the inner wall of the arc-shaped groove. The limiting plate, through the round rod, drives the outer edge of the pushing rod to slide down the inner wall of the cone, thereby assisting the outer edge of the side cone rod to slide in the inner wall of the cone, thus assisting the outer surface of the side cone rod to be inserted with the ground. Then, by rotating the adjusting rod, the outer edge of the limiting plate is limited to the inner wall of the arc-shaped groove, thereby ensuring the stable limiting of the side cone rod with the cone and ensuring the stable limiting of one end of the measuring tape.

[0012] 2. This agricultural experimental field measuring tool, through the cooperation of an adjusting plate and a connecting rod, uses the adjusting plate to drive the connecting rod to rotate, and the connecting rod to drive the adjusting gear to rotate. The adjusting gear then drives the side of the toothed plate to slide within the inner wall of the fixed cylinder, thereby assisting the separation of the convex surface of the positioning protrusion from the inner wall of the collar. This allows for the adjustment of the collar height at the outer edge of the fixed cylinder, facilitating the adjustment of the measuring tape's mounting height according to the required setup environment. Afterward, the adjusting plate is released, and the tension spring, through the rotating rod and the adjusting gear, pushes the convex surface of the positioning protrusion to engage and limit its position with the collar.

A measuring tape 23 is provided on the inner wall of the hanging frame 20. Through the cooperation of spring 5 and side cone rod 4, spring 5 pushes the side cone rod 4 to move in the inner wall of the cone cylinder 3. Then, the outer cone surface of the side cone rod 4 is inserted and limited by the external ground. With the addition of push rod 7, the bottom of push rod 7 near the outer edge is inclined. When push rod 7 moves down, the outer edge of push rod 7 pushes the side cone rod 4 to move away from the inner wall of the cone cylinder 3.

[0017] In a preferred embodiment, the top of the adjusting cylinder 2 is provided with a sliding groove 8, and the bottom of the inner wall of the sliding groove 8 is provided with an arc-shaped groove 9. The top of the push rod 7 is fixedly equipped with a round rod 10, and the top of the round rod 10 is rotatably connected to a limiting plate 11. The shape and size of the outer edge of the limiting plate 11 are adapted to the shape and size of the inner wall of the arc-shaped groove 9 and the inner wall of the sliding groove 8. The top of the limiting plate 11 is fixedly equipped with an adjusting rod 12. Through the cooperation of the adjusting rod 12 and the limiting plate 11, the outer edge of the limiting plate 11 is driven through the inner wall of the sliding groove 8 to the inner wall of the arc-shaped groove 9 by the adjusting rod 12. Then, the adjusting rod 12 is rotated to assist the outer edge of the limiting plate 11 in being limited to the inner wall of the arc-shaped groove 9. Then, the outer edge of the push rod 7 is limited to the inner wall of the cone cylinder 3 by the round rod 10 through the limiting plate 11.

[0018] In a preferred embodiment, a rotating rod 15 is rotatably connected to the bottom of the inner wall of the fixed cylinder 13, and an adjusting gear 14 is fixedly mounted on the top of the rotating rod 15. A connecting rod 25 is mounted on the top of the adjusting gear 14, and an adjusting plate 24 is fixedly mounted on the top of the connecting rod 25. Through the cooperation of the adjusting gear 14 and the adjusting plate 24, the adjusting plate 24 drives the adjusting gear 14 to rotate through the connecting rod 25, and the adjusting gear 14 drives the rotating rod 15 to rotate.

[0019] In a preferred embodiment, a tension spring 16 is fixedly connected to the side of the inner wall of the fixed cylinder 13, and the end of the tension spring 16 away from the inner wall of the fixed cylinder 13 is fixedly connected to the outer edge of the rotating rod 15. A toothed plate 17 is slidably connected to the inner wall of the fixed cylinder 13, and the protruding teeth of the toothed plate 17 mesh with the protruding teeth of the adjusting gear 14. A positioning protrusion 18 is fixedly mounted on the side of the toothed plate 17, and the outer edge of the positioning protrusion 18 is slidably sleeved with the inner wall of the fixed cylinder 13 and the inner wall of the collar 19. Through the cooperation of the tension spring 16 and the rotating rod 15, the tension spring 16 pulls the rotating rod 15, thereby assisting the rotating rod 15 to push the toothed plate 17 and the positioning protrusion 18 to move away from the inner wall of the fixed cylinder 13 through the adjusting gear 14.

[0020] In a preferred embodiment, a second spring 22 is fixedly connected to the top of the inner wall of the hanging frame 20, and a positioning rod 21 is fixedly connected to the bottom of the second spring 22. The shape and size of the positioning rod 21 near the bottom outer edge are adapted to the shape and size of the inner wall of the measuring tape 23. Through the cooperation of the second spring 22 and the positioning rod 21, the second spring 22 pushes the positioning rod 21 down in the inner wall of the hanging frame 20, thereby using the outer edge of the positioning rod 21 near the bottom to stably connect with the inner wall of the measuring tape 23.

[0021] In a preferred embodiment, there are four side cone rods 4, which are evenly distributed on the inner wall of the cone cylinder 3. The connection structure on the sides of the four side cone rods 4 is completely identical. By adding the four side cone rods 4, when a single push rod 7 slides in the inner wall of the cone cylinder 3, the outer edge of the push rod 7 near the bottom pushes the four side cone rods 4 to slide in the inner wall of the cone cylinder 3, thereby further assisting in the stable erection of the cone cylinder 3.

[0022] Working principle: When the device is in use, the cone cylinder 3 is inserted into the ground. Then, the adjusting rod 12 drives the outer edge of the limiting plate 11 through the inner wall of the sliding groove 8 to the inner wall of the arc-shaped groove 9. The limiting plate 11 then drives the outer edge of the pushing rod 7 to slide within the inner wall of the cone cylinder 3. This pushes the outer edge of the side cone rod 4 to slide within the inner wall of the cone cylinder 3, thus assisting the end of the side cone rod 4 away from the inner wall of the cone cylinder 3 to be inserted into the ground. This further assists in stabilizing the device's insertion into the ground. The positioning rod 21 is then moved upwards, assisting the bottom of the measuring tape 23 to overlap the bottom of the inner wall of the hanging frame 20. Finally, the positioning rod 21 is released. Spring 22 pushes the outer edge of positioning rod 21 to limit its position against the inner wall of measuring tape 23. Adjusting plate 24 drives adjusting gear 14 to rotate via connecting rod 25. Adjusting gear 14 then drives positioning protrusion 18 to move via toothed plate 17. This helps the convex surface of positioning protrusion 18 to separate from the inner wall of collar 19. Then, collar 19 moves along the outer edge of fixed cylinder 13, allowing collar 19 to adjust the height of measuring tape 23 according to the installation environment. Afterward, adjusting plate 24 is released, and tension spring 16 pulls rotating rod 15 to reset, thus helping the convex surface of positioning protrusion 18 to align with the inner wall of collar 19.
