[0002] Vegetation refers to the plant communities covering a certain area on the earth's surface. According to the classification of plant community types, it can be divided into meadow vegetation, forest vegetation, etc. It is closely related to natural environmental elements such as climate, soil, terrain, animal kingdom and water conditions. However, due to the large differences in terrestrial environments, a variety of vegetation types have been formed, which can be divided into multi-level classification series such as vegetation types, plant formations and associations.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 , a field vegetation survey and measurement device in this embodiment includes a base 1. By setting the base 1, the whole can be supported, making the whole more stable. A support rod 2 is fixed on the top of the base 1. A sliding rod 3 is slidably connected to the outer surface of the support rod 2. Scale tables are fixed on the outer surfaces of both the support rod 2 and the sliding rod 3. By setting the scale tables, the height of the vegetation can be measured. The measured value is the scale on the support rod 2 plus the scale on the sliding rod 3. A horizontal component 4 is fixed on the outer surface of the sliding rod 3. The horizontal component 4 is used to ensure that the support rod 2 is perpendicular to the ground.

[0022] In addition, a fixing ring 5 slidably connected to the support rod 2 is fixed at the bottom of the sliding rod 3. A fixing rod 6 is fixed inside the right side of the fixing ring 5. Threaded strips are fixed on the outer surface of the fixing rod 6. A through hole is opened on the right side of the fixing ring 5, and a threaded block is fixed on the outer surface of the through hole. By setting the threaded block, the through hole can be closed. When the fixing rod 6 is rotated, the fixing rod 6 will push the fixing plate 7 to move, so that the support rod 2 and the sliding rod 3 are fixed. Threaded holes adapted to the threaded strips are opened inside the threaded block. A fixing plate 7 is fixed on the left side of the fixing rod 6. Sponge pads are fixed on the left side of the fixing plate 7 and the left side wall of the inner cavity of the fixing ring 5. The sponge pads are natural sponge pads. By setting the sponge pads, the support of the fixing plate 7 is more stable, and at the same time, the damage to the support rod 2 caused during fixation is effectively prevented.

[0023] Furthermore, a control rod is fixed to the right side of the fixed rod 6. By providing the control rod, the fixed rod 6 can be conveniently controlled, thus effectively improving the overall practicality. A measuring assembly is rotatably connected inside the sliding rod 3 and penetrates outside the sliding rod 3. The measuring assembly includes a rotating rod 8 rotatably connected to the inside of the sliding rod 3. Two connecting plates are fixed to the outer surface of the rotating rod 8. A torsion spring 9 is fixed between the connecting plate and the sliding rod 3. By providing the torsion spring 9, after pulling the rotating rod 8 to rotate, under the action of the torsion spring 9, the rotating rod 8 will reset, making the whole more practical. A measuring tape 10 is fixed to the outer surface of the rotating rod 8 between the two connecting plates. The measuring tape 10 penetrates to the left side of the sliding rod 3. A limiting plate 11 is fixed to the left side of the measuring tape 10. By providing the limiting plate 11, the measuring tape 10 can be effectively prevented from being completely wound into the sliding rod 3.

[0024] Generally speaking, the height of the vegetation can be measured by the support rod 2 and the sliding rod 3, and the width of the vegetation can be measured by the measuring assembly. The overall structure is simple, effectively improving the practicality of the measuring device.

[0025] Please refer to Figure 2 , in order to make the measuring device easy to level, the leveling assembly 4 in this embodiment includes a mounting box 401 fixed to the sliding rod 3. By providing the mounting box 401, water can be stored. An installation hole is opened at the bottom of the mounting box 401. A sealing gasket is fixed to the outer surface of the installation hole. The inside of the sealing gasket is fixed to the sliding rod 3. By providing the sealing gasket, the sealing performance of the mounting box 401 is effectively improved, thus preventing water from flowing out through the connection.

[0026] In addition, hinge blocks 402 are fixed to both the left and right sides of the sliding rod 3 inside the mounting box 401. A connecting rod 403 is hinged inside the hinge block 402. A floating log 404 is fixed to the side of the connecting rod 403 away from the hinge block 402. By providing the floating log 404, the hinge block 402 can flip following the change of the water level. A water inlet pipe 405 is fixed to the top of the mounting box 401. A sealing cover is threadedly connected to the outer surface of the water inlet pipe 405. Observation windows 406 are inlaid on both the front and back sides of the mounting box 401. By providing the observation windows 406, the internal structure can be conveniently observed.

[0027] In this embodiment, the hinge block 402 includes a connecting block fixed to the sliding rod 3. A rotating rod penetrating to the front of the connecting block is rotatably connected inside the connecting block. The outer surface of the rotating rod is fixed to the connecting rod 403. A prompt arrow is provided on the front of the rotating rod. When the floating log 404 is offset due to the change of the water level, the connecting rod 403 and the prompt arrow can be pushed to rotate.

[0028] Generally speaking, when the measuring device is not level with the ground, the water level inside the installation box 401 is inclined as a whole, so that the floating log 404 pushes the connecting rod 403 and the lifting arrow to deflect, enabling the surveyor to quickly level the measuring device according to the pointer of the lifting arrow. The overall structure is simple, effectively improving the overall practicality.

[0029] The working principle of the above embodiment is as follows:

[0030] Place the base 1 on the ground. If the ground is inclined at this time, the water inside the installation box 401 will be inclined, causing the floating log 404 to push the rotating rod to deflect. At this time, by observing the prompt arrow above the rotating rod, it can be known whether the measuring device is in a horizontal state. At this time, it can be adjusted according to the deflection angle of the lifting arrow to ensure that the measuring device is level with the ground. After the adjustment is completed, the measurement can be completed by pulling the sliding rod 3. The measured value is the sum of the sliding rod 3 and the scale on the support rod 2. The overall structure is simple, and the measuring device can be quickly leveled, making the measurement result more accurate.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
