Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, specifically a grassland monitoring vegetation cover acquisition device. Background Technology

[0002] A grassland vegetation cover acquisition device is a specialized instrument used for the scientific measurement and analysis of grassland vegetation cover. It typically consists of a grid frame, support legs, a height adjustment mechanism, scale blocks, and other auxiliary measuring tools, enabling it to accurately record vegetation cover conditions to assess ecological health.

[0003] Existing vegetation cover acquisition devices typically use the grid filling method for measurement. However, this method requires human visual observation of vegetation coverage within different grids, which are then marked with different colors before vegetation cover is calculated. In this process, if the area to be monitored is large, the grid frame also needs to be enlarged accordingly, making it inconvenient for operators to carry. Furthermore, relying solely on visual observation by operators can easily lead to errors in measurement results due to differences in individual experience. Summary of the Invention

[0004] The purpose of this invention is to provide a grassland monitoring and vegetation cover acquisition device to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Grassland vegetation cover acquisition device, including:

[0007] Two grid frames;

[0008] A mesh body, wherein the mesh body is disposed between two mesh frames;

[0009] A fixing rod is installed around the bottom of the grid frame;

[0010] It also includes a perforated fixing block, which is installed on the top of two grid frames close to each other on one side. A rotating block is installed on one side of the grid frame, and a rotating bracket is installed on the other side of the grid frame. A rotating column is installed inside the rotating block, and the two ends of the rotating column are rotatably connected to the rotating bracket. A bolt is installed between the two perforated fixing blocks. A sliding groove is opened on the top of one side of each of the two grid frames. A scale block is slidably connected inside the sliding groove. The scale block is provided with several scale lines.

[0011] The inside of the slide is provided with a fixing component for fixing the scale block;

[0012] The mesh frame is provided with mounting components for mounting the mesh body.

[0013] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0014] In one alternative: the fixing component includes a movable groove, which is opened at the top of the scale block. A movable plate is slidably connected inside the movable groove. A spring is fixedly connected between the movable plate and the movable groove. A locking post is installed on the side of the movable plate away from the spring. A plurality of locking slots matching the locking posts are opened inside the movable groove.

[0015] In one alternative: the mounting assembly includes an L-shaped support plate, which is mounted around the top of the grid body, and a first screw is installed between the L-shaped support plate and the grid frame.

[0016] In one alternative: the fixing rod is provided with an adjustment component for adjusting the height of the grid frame.

[0017] In one alternative embodiment: the adjusting assembly includes a movable rod that is slidably connected to the outer wall of a fixed rod. The movable rod has a first threaded hole, and the fixed rod has several second threaded holes. A second screw is installed between the first threaded hole and the second threaded hole, and the bottom end of the movable rod is tapered.

[0018] In one alternative: the cross-sectional shape of both the groove and the slider at the lower end of the scale block is cross-shaped.

[0019] In one alternative: the two mesh frames are symmetrically arranged.

[0020] In one alternative: the rotating block is convex in shape.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention achieves folding of the grid frame by allowing one side of the grid frame to rotate around the rotating bracket until it is parallel to the grid frame on the other side, which greatly reduces the transportation volume and improves the portability for field operations. At the same time, the movable scale block makes the measurement more accurate. The operator only needs to push the moving plate to disengage the locking pin from the slot to adjust the scale position, and the spring will automatically lock it when the hand is released, avoiding the errors caused by traditional handheld rulers.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, such as Figures 1-5 As shown, the grassland monitoring vegetation cover acquisition device includes: two grid frames 100, a grid body 200, a fixing rod 300, and a perforated fixing block 401. The grid body 200 is disposed between the two grid frames 100. The fixing rod 300 is installed around the bottom of the grid frame 100. The perforated fixing block 401 is installed on the top of the two grid frames 100 on one side close to each other. A rotating block 402 is installed on one side of the grid frame 100, and a rotating bracket 403 is installed on the other side of the grid frame 100. A rotating column is installed inside the rotating block 402. 407, the two ends of the rotating column 407 are rotatably connected to the rotating bracket 403, and bolts 404 are installed between the two perforated fixing blocks 401. A sliding groove 405 is provided on the top of one side of each of the two grid frames 100. A scale block 406 is slidably connected inside the sliding groove 405. The scale block 406 is provided with several scale lines. By rotating one side of the grid frame 100, the grid frame 100 on one side drives the rotating bracket 403 to rotate with the assistance of the rotating column 407, so that the grid frame 100 on one side is parallel to the grid frame 100 on the other side, thus achieving folding.

[0031] The inside of the slide 405 is provided with a fixing component for fixing the scale block 406;

[0032] The mesh frame 100 is provided with mounting components for mounting the mesh body 200.

[0033] In one embodiment, such as Figure 3 As shown, the fixing component includes a movable groove 501, which is located on the top of the scale block 406. A movable plate 502 is slidably connected inside the movable groove 501. A spring 503 is fixedly connected between the movable plate 502 and the movable groove 501. A locking post 504 is installed on the side of the movable plate 502 away from the spring 503. The sliding groove 405 has several locking slots 505 that match the locking posts 504. By pushing the movable plate 502 backward, the movable plate 502 compresses the spring 503. At this time, the movable plate 502 synchronously drives the locking post 504 to move, causing the locking post 504 to disengage from the locking slot 505, and then the scale block 406 can be moved. When it is necessary to fix the scale block 406, by releasing the movable plate 502, under the action of the spring 503, the movable plate 502 drives the locking post 504 to engage with the inside of the locking slot 505, thereby achieving fixation.

[0034] In one embodiment, such as Figure 1 As shown, the mounting assembly includes an L-shaped support plate 601, which is installed around the top of the grid body 200. A first screw 602 is installed between the L-shaped support plate 601 and the grid frame 100. By installing the first screw 602 between the L-shaped support plate 601 and the grid frame 100, the L-shaped support plate 601 can be fixed, making it easy to replace the grid body 200 with different specifications.

[0035] In one embodiment, such as Figure 4 As shown, the adjustment assembly includes a movable rod 701, which is slidably connected to the outer wall of the fixed rod 300. The movable rod 701 has a first threaded hole 702, and the fixed rod 300 has a plurality of second threaded holes 703. A second screw 704 is installed between the first threaded hole 702 and the second threaded hole 703. The bottom end of the movable rod 701 is tapered. By moving the movable rod 701 up and down, and then aligning the second threaded hole 703 with the first threaded hole 702, the second screw 704 is installed inside the first threaded hole 702 and the second threaded hole 703, thus achieving fixation.

[0036] In one embodiment, such as Figure 1 and Figure 5 As shown, the cross-sectional shape of the slider at the lower end of the slide groove 405 and the scale block 406 is cross-shaped; this facilitates sliding while preventing the scale block 406 from coming off.

[0037] In one embodiment, such as Figure 1 As shown, the two grid frames 100 are symmetrically arranged, which makes the device structure more balanced and improves stability.

[0038] In one embodiment, such as Figure 2 As shown, the rotating block 402 is convex in shape.

[0039] The above embodiments disclose a grassland monitoring vegetation cover acquisition device. In use, by first installing grid bodies 200 of different specifications, and then fixing the L-shaped support plate 601 between the L-shaped support plate 601 and the grid frame 100 with a first screw 602, the vegetation cover is monitored by filling the grid. During this process, pushing the moving plate 502 backward causes it to compress the spring 503. Simultaneously, the moving plate 502 drives the locking post 504 to move, causing the locking post 504 to disengage from the locking slot 505, after which the target can be moved. Ruler block 406 helps personnel more accurately determine the area covered by vegetation. When it is necessary to fix the ruler block 406, by releasing the moving plate 502, under the action of the spring 503, the moving plate 502 drives the locking post 504 to be locked into the inside of the locking slot 505, thereby achieving fixation. When it is no longer needed, the grid frame 100 on one side can be rotated, so that the grid frame 100 on one side drives the rotating bracket 403 to rotate with the assistance of the rotating post 407, thereby making the grid frame 100 on one side parallel to the grid frame 100 on the other side, achieving folding and easy storage.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
