Description

Technical Field

[0001] This utility model relates to the technical field of vegetation root density measurement tools, and in particular to a root density measurement grid. Background Technology

[0002] Traditionally, to measure vegetation root density, a sampling pit is excavated in the target area to construct the test profile. Nails are then fixed around the profile, and marking ropes are stretched across the profile using these nails as a base, creating a marked grid. Root density is then investigated through this grid. This process is overly complex. To simplify, current methods involve stretching marking ropes within a measuring frame to pre-form a marked grid, then fixing the frame to the profile. Root density is then investigated through this grid. However, when using this method, protrusions on the profile prevent the measuring tool from being parallel to the profile, affecting accuracy. Forcing the tool parallel to the profile may damage both the tool and the profile. Utility Model Content

[0003] The purpose of this invention is to provide a root density measurement grid that addresses the existing technical situation, thereby avoiding damage to the measurement grid or the measured profile under pressure and circumventing the problem that the measurement grid is not parallel to the measured profile.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A root density measurement grid includes a measurement frame, which is a rectangular frame structure comprising four frame rods connected end to end, and each frame rod is provided with a slide rail.

[0006] The measuring frame is provided with several dividing mark systems along both the horizontal and vertical directions. Each dividing mark system includes a dividing rope, a first slider, a spring, a second slider, and a third slider. The first slider has a first through hole. One end of the dividing rope passes through the slide rail provided in the corresponding frame rod, the first through hole provided in the first slider, and the spring in sequence, and its end is connected to the second slider. The other end of the dividing rope passes through the slide rail provided in the corresponding frame rod, and its end is connected to the third slider. The spring is in a compressed state, and both the first slider and the third slider abut against the corresponding frame rod.

[0007] Furthermore, the separating rope is detachably connected to the third slider, and each of the frame rods is equipped with a scale.

[0008] Furthermore, the third slider is provided with a second through hole, and its side is provided with a groove that extends into the second through hole. The end face of the third slider away from the corresponding frame rod is provided with a limiting groove, and it also includes a limiting block. The thickness of the limiting block is less than the width of the slide rail provided in the frame rod. The limiting block is set in the limiting groove. The separating rope passes through the second through hole provided in the third slider and is connected to the limiting block.

[0009] Furthermore, each of the frame rods is provided with a sliding groove, and the first slider and the third slider are both located in the sliding groove provided on the corresponding frame rod and are adapted to the sliding groove provided on the corresponding frame rod.

[0010] Furthermore, both the first slider and the third slider are cylindrical structures, and the diameters of the first slider and the third slider are adapted to the width of the grooves provided on the corresponding frame rods.

[0011] Furthermore, the separating cord is made of metal wire.

[0012] Furthermore, the frame rods of the measuring frame are connected end to end by connectors.

[0013] Furthermore, the connector is provided with a connecting hole, which is used to fix the measuring frame on the section to be measured.

[0014] Furthermore, the frame rod is made of plastic.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model provides a root density measurement grid, in which several dividing mark systems are set along the horizontal and vertical directions in the measurement frame, thereby dividing the measurement frame into several measurement units. The dividing mark system adopts a flexible design, so that the dividing rope can adapt to the raised parts of the test section when it touches them. This avoids the damage of the measurement grid and the test section by pressure, and also avoids the problem that the measurement grid is not parallel to the test section, thus improving the accuracy of the measurement.

[0018] 2. This utility model provides a root density measurement grid, in which the dividing rope and the third slider are designed to be detachably connected, so that the dividing mark system can be quickly added or removed. At the same time, the spacing of the dividing mark system in the measurement frame can be adjusted according to the scale on the frame rod to meet different measurement needs.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1:

[0029] Please see Figures 1-4 As shown, a root density measurement grid includes a measurement frame 1, which is a rectangular frame structure consisting of four frame rods 3 connected end to end, and each frame rod 3 is provided with a slide rail 301.

[0030] Specifically, the frame rods 3 of the measuring frame 1 are connected end to end by connectors 4.

[0031] More specifically, the connector 4 is provided with a connecting hole 401, which is used to fix the measuring frame 1 to the section to be measured. In use, the measuring frame 1 is fixed to the section to be measured by nails.

[0032] In this embodiment, for example, the frame rod 3 is a plastic part; the frame rod 3 and the connector 4 are connected by plugging.

[0033] The measuring frame 1 is provided with several dividing mark systems 2 along both the horizontal and vertical directions. The dividing mark system 2 is used to divide the measuring frame 1 into several measuring units, that is, to form a mark grid within the measuring frame 1.

[0034] Specifically, the separating marking system 2 includes a separating rope 5, a first slider 6, a spring 7, a second slider 8, and a third slider 9. The first slider 6 has a first through hole 601. One end of the separating rope 5 passes through the slide 301 in the corresponding frame rod 3, the first through hole 601 in the first slider 6, and the spring 7 in sequence, and its end is connected to the second slider 8. The other end of the separating rope 5 passes through the slide 301 in the corresponding frame rod 3, and its end is connected to the third slider 9. The spring 7 is in a compressed state, and both the first slider 6 and the third slider 9 abut against the corresponding frame rod 3.

[0035] According to the above design, the dividing mark system 2 is a flexible structure, which allows the dividing rope 5 to adapt to changes when it touches the raised part on the test section (when the dividing rope 5 touches the raised part on the test section, the spring 7 is compressed and the second slider 8 moves closer to the first slider 6).

[0036] In this embodiment, for example, the separator rope 5 is a metal wire.

[0037] In addition, the separator cord 5 can also be a non-metallic wire.

[0038] In the above technical solution, preferably, a positioning groove 602 is provided on the end face of the first slider 6 near the second slider 8, and the end of the spring 7 near the first slider 6 is located in the positioning groove 602. The positioning groove 602 is used for positioning the spring 7.

[0039] It should be noted that, given that the dividing rope 5 is relatively thin, the misalignment distance between the horizontal dividing rope 5 and the vertical dividing rope 5 within the measuring frame 1 is negligible.

[0040] Example 2:

[0041] Please see Figures 5-7 As shown, based on Embodiment 1, the separating rope 5 is detachably connected to the third slider 9, and each frame rod 3 is provided with a scale (not shown in the figure).

[0042] By designing the separator rope 5 and the third slider 9 as a detachable connection, the separator marking system 2 within the measuring frame 1 can be added or removed as needed, and its arrangement can be redistributed evenly with reference to the scale on the frame rod 3 to accommodate different measurement requirements. For example, Figure 1 In the diagram, the marking grid is 10×10, but it can be adjusted to 8×8, 5×5, etc., depending on the measurement requirements.

[0043] Specifically, the third slider 9 is provided with a second through hole 901, and its side is provided with a groove 903 that extends into the second through hole 901. The end face of the third slider 9 away from the corresponding frame rod 3 is provided with a limiting groove 902, and it also includes a limiting block 10. The thickness of the limiting block 10 is less than the width of the slide 301 provided in the frame rod 3 (so that the limiting block 10 can pass through the slide 301 provided in the frame rod 3). The limiting block 10 is set in the limiting groove 902. The separating rope 5 passes through the second through hole 901 provided in the third slider 9 and is connected to the limiting block 10.

[0044] According to the above design, the separator rope 5 and the third slider 9 are designed for quick disassembly, which facilitates rapid assembly and disassembly. The quick disassembly operation is as follows: pull the limiting block 10 out from the limiting groove 902, and move the separator rope 5 out through the gap groove 903.

[0045] In the above technical solution, preferably, each frame rod 3 is provided with a groove 302, and the first slider 6 and the third slider 9 are both located in the groove 302 provided on the corresponding frame rod 3 and are adapted to the groove 302 provided on the corresponding frame rod 3. After adding the groove 302 to the first slider 6 and the third slider 9, it is convenient to adjust their positions when rearranging the separating marking system 2.

[0046] In this embodiment, for example, both the first slider 6 and the third slider 9 are cylindrical structures, and the diameters of the first slider 6 and the third slider 9 are adapted to the width of the groove 302 provided on the corresponding frame rod 3.

[0047] In addition, the second slider 8 is also a cylindrical structure.

[0048] Of course, the above are only preferred embodiments of this utility model and are not intended to limit the scope of application of this utility model. Therefore, any equivalent changes made to the principle of this utility model should be included within the protection scope of this utility model.
