Description

Technical Field

[0001] This utility model relates to the field of grassland ecological parameter measurement technology, and in particular to a grassland vegetation cover and height measurement device. Background Technology

[0002] Grassland vegetation cover and height are key indicators for assessing grassland ecosystem health, productivity, and species diversity. In field ecological surveys, quadrat methods are a commonly used technique for measuring these parameters, typically using gridded quadrats or partitions for fixed-point observation and data collection.

[0003] However, when using existing measuring equipment, surveyors often need to adjust the vertical position of the quadrat frame according to the actual growth height of the vegetation. This adjustment process mostly relies on manual operation, such as through telescopic rods or locking bolts on the bracket. The operation is not only cumbersome, but also greatly reduces work efficiency when it is necessary to frequently change the measuring points or conduct large-scale surveys.

[0004] More importantly, the traditional quadrat grid is usually a fixed structure, and its grid shape and mesh size cannot be changed once it is made. The limitation of this design is that when facing different types or different growth stages of grassland, such as sparse grassland or dense shrubland, the fixed grid is difficult to provide the optimal observation scale, resulting in a large deviation in the cover estimation, which affects the accuracy and universality of the measurement results. Existing grassland measurement tools generally have problems such as cumbersome operation procedures, low adjustment efficiency, and poor adaptability, making it difficult to meet the growing demand of modern ecological research for measurement accuracy and efficiency.

[0005] Therefore, this utility model proposes a grassland vegetation cover and height measuring device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing grassland vegetation cover and height measuring devices, such as cumbersome and laborious height adjustment process, low efficiency, fixed measuring grid structure, and poor adaptability, this utility model aims to provide a grassland vegetation cover and height measuring device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a grassland vegetation cover and height measuring device, including: a column, a protective shell, a telescopic cylinder that can be inserted into the soil for fixing the device; and a lifting drive mechanism, a fixing plate, a rotating column, a locking plate, a drive assembly, and an adjustment structure.

[0008] The lifting drive mechanism is housed within the protective casing and includes a motor, a bevel gear, and a threaded rod. The bevel gear is connected to the output end of the motor and is threadedly driven by the threaded rod, which is coaxially fixed to the column, to achieve electric lifting of the column.

[0009] Furthermore, the fixed plate is fixedly connected to the upper end of the column, the rotating column is rotatably connected to the fixed plate, the locking plate is fixed to the rotating column, and the driving component is used to drive the rotating column to rotate, thereby controlling the locking plate to switch between the two states of locking the column and disengaging from the column; the adjustment structure includes a connecting block rotatably sleeved on the column, a horizontal axis rotatably connected to the connecting block, and a mesh connected to the horizontal axis. This structure can adjust the horizontal angle around the column when the locking plate disengages from the column.

[0010] Preferably, the adjustment structure further includes a limiting ring fixed on the connecting block and a rotating ring rotatably sleeved on the outer periphery of the limiting ring. The horizontal axis is connected to the limiting ring through the rotating ring. This design allows the horizontal axis to slide and rotate, thereby achieving flexible adjustment of the shape of the mesh coverage.

[0011] Preferably, the connecting block has a limiting groove for accommodating and defining the limiting ring. This structure ensures the stability of the connection between the limiting ring and the connecting block.

[0012] Preferably, the adjustment structure further includes a guide rail fixed along its length on the horizontal axis and a spherical slider slidably connected to the guide rail. The mesh is connected to the horizontal axis through the spherical slider, and the operator can conveniently adjust the mesh size of the mesh by moving the position of the spherical slider on the guide rail.

[0013] Preferably, the connecting block is also provided with a receiving groove, which is used to provide clearance space for the rotating handle when the connecting block is rotated around the column, thereby effectively avoiding motion interference between the components.

[0014] Preferably, one end of the connecting plate in the drive assembly is fixedly connected to the rotating column, and the other end is fixedly connected to the rotating handle, forming a rigid transmission path to ensure the accuracy of operation.

[0015] Preferably, the device further includes a positioning sensor, which is disposed on the outer or inner wall of the telescopic cylinder for assisting positioning or data acquisition.

[0016] Preferably, the inner ring of the bevel gear is threaded, and the outer surface of the threaded rod is threaded to match it. The two are driven by threaded engagement. This transmission method not only runs smoothly, but also has good self-locking performance.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of existing grassland measuring devices relying on manual operation for height adjustment, which is cumbersome and inefficient, by setting up a lifting drive mechanism composed of a motor, bevel gear and threaded rod to drive the column to lift. It achieves the technical effect of electric lifting, saving time and effort and precise adjustment.

[0019] 2. This utility model achieves rapid locking or releasing of the column by setting an adjustment and locking assembly consisting of a rotating handle, a connecting plate, a rotating column, and a locking plate. This solves the problem of inconvenience in switching between adjusting the horizontal angle and fixing the height of the measuring device, and achieves the technical effect of flexible operation mode switching and greatly improving the convenience of on-site operation.

[0020] 3. This utility model solves the limitations of traditional measuring nets, which have a single shape and fixed mesh size, making it difficult to adapt to different grassland vegetation characteristics, by setting an adjustment structure including a horizontal axis, guide rail, spherical slider and rotatable connecting block. It realizes the autonomous adjustment of the covering shape and mesh size of the net, and enhances the technical effect of the device's applicability and measurement practicality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example: Please refer to Figures 1 to 4 This utility model provides a grassland vegetation cover and height measuring device, which includes a column 1 and a telescopic cylinder 3 that can be inserted into the soil for fixing. A protective shell 4 is connected to the upper end of the telescopic cylinder 3. The protective shell 4 is sleeved on the outside of the column 1 and provides a space for the lifting drive mechanism inside. A positioning sensor 5 is provided on the outer or inner wall of the telescopic cylinder 3. The positioning sensor 5 is used to assist in positioning or data acquisition.

[0029] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the grassland vegetation cover and height measuring device includes a lifting drive mechanism and an adjustment assembly that integrates locking, rotation and measurement. Furthermore, the two form a specific structural cooperation and transmission relationship, realizing the electric adjustment of height and the coordinated adjustment of measurement angle and measurement grid state.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The lifting drive mechanism, located inside the protective shell 4, includes a motor 7, a bevel gear 8, and a threaded rod 6. The output end of the motor 7 is connected to the bevel gear 8 for transmission. The inner ring of the bevel gear 8 is threaded, and the outer surface of the threaded rod 6 is threaded to match it. At the same time, the threaded rod 6 is coaxially fixedly connected to the column 1. When the motor 7 is working, it drives the bevel gear 8 to rotate. The bevel gear 8 is driven by its internal thread meshing with the external thread of the threaded rod 6, thereby driving the threaded rod 6 to drive the column 1 to perform a smooth vertical lifting motion.

[0031] A fixing plate 9 is fixedly connected to the upper end of the column 1. A rotating hole 10 is provided on the fixing plate 9. A rotating column 12 is rotatably connected to the fixing plate 9 and passes through the rotating hole 10. A locking plate 11 is fixedly mounted on the rotating column 12. A rotating handle 13 is fixedly connected to the rotating column 12 through a connecting plate 14. By operating the rotating handle 13, the locking plate 11 can be driven to rotate through the connecting plate 14 and the rotating column 12, so that the locking plate 11 selectively engages and clamps the column 1 or disengages from the column 1.

[0032] The adjustment structure 2 includes a connecting block 207, a horizontal shaft 201, and a partition net 204. The connecting block 207 is rotatably sleeved on the column 1. The horizontal shaft 201 is rotatably connected to the connecting block 207, and the partition net 204 is connected to the horizontal shaft 201. When the locking plate 11 disengages from the column 1, the operator can drive the connecting block 207 to rotate freely around the column 1 to adjust the horizontal measurement angle of the partition net 204. After adjustment, the locking plate 11 is driven to lock the column 1, thereby locking the horizontal angle and enabling the entire adjustment structure 2 to rise and fall synchronously with the column 1.

[0033] As a preferred embodiment, in order to achieve flexible adjustment of the shape of the mesh 204, please refer to... Figure 2 and Figure 4 In the adjusting structure 2, a limiting ring 206 is fixed on the connecting block 207, and a limiting groove 208 is also provided on the connecting block 207 to accommodate and limit the limiting ring 206. The horizontal shaft 201 is rotatably sleeved on the outer periphery of the limiting ring 206 through the rotating ring 205. The rotating ring 205 is fixedly connected to the horizontal shaft 201. This structure allows the horizontal shaft 201 to rotate around the axis of the limiting ring 206 and slide along its axial direction, thereby changing the overall shape of the partition net 204.

[0034] As another preferred embodiment, in order to achieve autonomous adjustment of the mesh size of the 204 mesh, please refer to... Figure 4 A guide rail 202 is fixed on the horizontal axis 201 along its length. The mesh 204 is connected to the horizontal axis 201 through a spherical slider 203, and the spherical slider 203 can slide in the guide rail 202. By moving the grid line connected to the spherical slider 203, the size of the mesh can be changed to adapt to different densities of vegetation.

[0035] As another preferred embodiment, to facilitate the rotation of the connecting block 207 and avoid structural interference, please refer to... Figure 2 and Figure 4 The connecting block 207 is also provided with a receiving groove 209. When it is necessary to rotate the connecting block 207 around the column 1 to adjust the horizontal angle, the receiving groove 209 provides space for the rotating handle 13 to avoid the rotation, ensuring the smoothness of the adjustment process.

[0036] As another preferred embodiment, to clarify the driving method of the locking plate 11, please refer to... Figure 3 The rotating handle 13 is fixedly connected to one end of the connecting plate 14, and the other end of the connecting plate 14 is fixedly connected to the rotating column 12, forming a rigid transmission structure. This ensures that the action of operating the rotating handle 13 can be accurately transmitted to the rotating column 12, thereby controlling the rotation of the locking plate 11.

[0037] As a further limitation on the transmission method of the lifting drive mechanism, the inner ring of the bevel gear 8 is provided with threads, and the outer surface of the threaded rod 6 is provided with matching threads. The two achieve transmission through thread meshing, which results in smooth transmission and self-locking.

[0038] Working principle: When the device is working normally, first insert the telescopic cylinder 3 and the positioning sensor 5 into the soil, then turn on the motor 7 on the inner wall of the protective shell 4, so that its output end drives the bevel gear 8 to rotate, thereby causing the threaded rod 6 to rotate on the inner wall of the bevel gear 8, and then causing the threaded rod 6 to drive the column 1 to move vertically up and down together. At this time, manually turn the rotating handle 13 to drive the connecting plate 14 to rotate, thereby causing the rotating column 12 to rotate and slide in the rotating hole 10 on the inner wall of the fixed plate 9, so that the locking plate 11 rotates around the rotating column 12 to open and close. When closed, the locking plate 11 locks the column 1 and moves with it, thereby adjusting the height. When open, the connecting block 207 can rotate around the column 1 to adjust the horizontal angle, thus realizing the height and horizontal adjustment of the device, making it easier to measure height and improving the practicality of the device.

[0039] Adjustment structure 2 is used to adjust the mesh size of the mesh 204. First, rotate handle 13 to place it in receiving groove 209 and drive connecting block 207 to move and rotate together. Limiting ring 206 is placed in limiting groove 208. Horizontal shaft 201 slides on limiting ring 206 through rotating ring 205. Thus, during the rotation of connecting block 207, horizontal shaft 201 can adjust its angle through rotating ring 205 and limiting ring 206, thereby adjusting the covering shape of mesh 204. Furthermore, by moving mesh 204, the connected spherical slider 203 can slide on guide rail 202, thereby independently adjusting the size of the mesh. Ultimately, the size and shape of mesh 204 are adjusted, improving the practicality of the device.
