[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Combination Figures 1 to 3 A field experiment marking device includes a top plate 1 and a hook plate 6. Support plates 2 are fixedly connected to the left and right sides of the top plate 1. Moving wheels 3 are fixedly connected to the bottom of the support plates 2. Support mechanisms 5 are provided on the two support plates 2. Limiting mechanisms 4 are provided on the support mechanisms 5.

[0033] The support mechanism 5 includes a movable component 51 and a fixed component 52, with the fixed component 52 disposed on the movable component 51;

[0034] The moving component 51 includes a long rod 512, which is fixedly connected between two support plates 2. Slide plates 511 are fixedly connected to the upper and lower surfaces of the long rod 512 respectively. A long plate 514 is fixedly connected to the top of the hook plate 6. A connecting rod 515 is fixedly connected to the top of the long plate 514. A circular groove 513 is opened inside the connecting rod 515. Slide grooves 516 are opened at the top and bottom of the inner wall of the circular groove 513.

[0035] The circular slot 513 is set to be open on both the left and right sides. The surface of the long rod 512 is inserted into the inside of the circular slot 513. There are two slide plates 511 and two slide grooves 516. The surface of the slide plate 511 is slidably connected to the inside of the slide groove 516.

[0036] The fixing component 52 includes insertion slots 521, which are densely arranged inside the long rod 512. Square seats 526 are fixedly connected to the front and rear sides of the long plate 514 respectively. A second reinforcing plate 529 is fixedly connected between the bottom of the square seat 526 and the long plate 514. A T-shaped groove 525 is opened on the top of the square seat 526. A T-shaped block 527 is slidably connected inside the T-shaped groove 525. A movable plate 524 is fixedly connected to the top of the T-shaped block 527. An installation plate 523 is fixedly connected to the top of the movable plate 524. A plug rod 522 is fixedly connected to the side of the installation plate 523 near the long rod 512. A first reinforcing plate 528 is fixedly connected to the bottom of the installation plate 523 and the left and right ends of the movable plate 524 respectively. The insertion slots 521 are set with openings on the front and rear sides. The surface of the plug rod 522 is inserted into the insertion slot 521. The plug rod 522 is set on the left and right sides of the connecting rod 515.

[0037] Furthermore, the connecting rod 515 moves on the surface of the long rod 512, while the sliding plate 511 slides in the sliding groove 516. After adjusting the distance between the two hook plates 6, the moving plate 524 can be pushed again to drive the T-block 527 to slide in the T-groove 525. At the same time, the moving plate 524 drives the mounting plate 523, and the mounting plate 523 drives the insertion rod 522 to be inserted into the insertion slot 521, which facilitates the positioning and fixing of the connecting rod 515. This makes it convenient for the hook plate 6 to distinguish and divide the required experimental field width when digging trench lines in the land.

[0038] Example 2

[0039] See Figure 1-4 Furthermore, based on Embodiment 1, the limiting mechanism 4 further includes a connecting seat 44, which is densely and fixedly connected to the left and right sides of the square base 526. A connecting plate 41 is fixedly connected to the side of the moving plate 524 away from the long plate 514. Telescopic plates 45 are fixedly connected to the bottom ends of the connecting plate 41 respectively. A long groove 43 is opened on the top of the connecting seat 44. Screws 42 are threadedly connected to the connecting seat 44 and the telescopic plate 45. The top of the long groove 43 is set as an opening, and the surface of the telescopic plate 45 is inserted into the long groove 43.

[0040] Furthermore, after the telescopic plate 45 is stretched and inserted into the long slot 43, the connecting seat 44 and the telescopic plate 45 are threadedly fixed by the screw 42, which facilitates the position limit and fixation of the moving plate 524, and can fix the position of the long plate 514.

[0041] In actual operation, when this device is used to divide the space for field experiments, it is necessary to use the hook plate 6 to dig a horizontal trench line in the soil. At this time, it is necessary to adjust the distance between the two hook plates 6. The long plate 514 can be pushed to move the connecting rod 515 on the surface of the long rod 512, while the sliding plate 511 slides in the sliding groove 516. After adjusting the distance between the two hook plates 6, the moving plate 524 can be pushed again to move the T-block 527 in the T-slot 525. At the same time, the moving plate 524 moves the mounting plate 523, and the mounting plate 523 moves the insertion rod 522 to be inserted into the insertion slot 521, which facilitates the limiting and fixing of the position of the connecting rod 515.

[0042] After the telescopic plate 45 is stretched and inserted into the long groove 43, the connecting seat 44 and the telescopic plate 45 are threaded and fixed with screws 42, which makes it easy to limit and fix the position of the moving plate 524. This can fix the position of the long plate 514. At the same time, with the cooperation and support of the second reinforcing plate 529 and the first reinforcing plate 528, the hook plate 6 can move stably under the trench line. When the hook plate 6 is held by the handle on the top plate 1, the required experimental ground width can be distinguished when the hook plate 6 is digging trench lines in the ground.
