A tree growth height measuring device

Abstract

This utility model discloses a tree height measuring device, relating to the field of height measurement technology. It includes a height measuring rod body with graduations on its surface. A rotating seat is fixedly connected to the output end of the height measuring rod body. A pin is rotatably connected to the end of the rotating seat away from the height measuring rod body. A marking mechanism is fixedly connected to the rotating seat via the pin. The marking mechanism assists the user in observing the specific height of the top of the height measuring rod body. Workers measure the specific height of trees using the height measuring rod body, and then bring the measuring rod close to the top of the tree. Compared to directly observing the top of the height measuring rod body, there is a certain angle between the measuring rod and the human eye when observing the measuring rod, making it easier to align with the top of the tree. After adjusting the height of the measuring rod once, the worker can directly move the height measuring rod body in its output state to the bottom of the next sapling for the next test. This solves the problem that existing tree height measuring devices are difficult to use for batch testing of multiple trees.

Description

Technical Field

[0001] This utility model relates to the field of height measurement technology, and in particular to a device for measuring the growth height of trees. Background Technology

[0002] Tree height measurement devices (particularly suitable for measuring seedlings) are specialized equipment designed to monitor and analyze the growth process of seedlings. These devices are commonly used in forestry, horticulture, and agriculture to help researchers and growers track seedling growth rates, health conditions, and responses to environmental changes. Currently, most existing tree height measurement devices achieve their effects using the following technologies;

[0003] Traditional optical measurement techniques are designed based on geometric trigonometry or proportional principles, and height conversion is achieved by manually observing angles or scales;

[0004] Ultrasonic ranging technology calculates distance by transmitting and receiving ultrasonic signals, and combines angle measurement to estimate altitude.

[0005] Laser ranging and 3D modeling technology uses laser pulses to obtain spatial coordinates and combines them with algorithms to construct 3D models.

[0006] Photogrammetry and computer vision enable non-contact measurement through image acquisition and algorithm analysis; telescopic poles and mechanical measurement technology enable accurate readings through physical contact or assisted positioning.

[0007] Currently, existing tree height measurement devices have been found to have at least the following technical problems in practical use;

[0008] Existing tree height measurement devices mostly use height measuring poles to measure the height of trees under five meters to check if they meet growth standards. During the planting stage of saplings, it is necessary to measure the height of saplings in batches. However, when measuring saplings in batches, the existing height measuring poles need to be adjusted to fit the different heights of the trees, as the height of the trees varies. Furthermore, the top of the height measuring pole is difficult to align quickly with the tree due to its height, making batch testing difficult. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a tree growth height measuring device, which solves the problem that existing tree growth height measuring devices are difficult to use for batch testing of multiple trees.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A tree height measuring device includes a height measuring rod body with graduations on its surface. A rotating seat is fixedly connected to the output end of the height measuring rod body. A pin is rotatably connected to the end of the rotating seat away from the height measuring rod body. A marking mechanism is fixedly connected to the rotating seat via the pin. The marking mechanism is used to assist the user in observing the specific height of the top of the height measuring rod body. The marking mechanism includes a connecting rod, a sleeve rod is slidably connected to one end of the connecting rod, and a clamping bolt is threadedly connected to the top of the connecting rod near the sleeve rod.

[0012] Preferably, the end of the connecting rod furthest from the sleeve is inserted into the pin.

[0013] Preferably, the end of the connecting rod away from the sleeve rod is fixedly connected to a first mating plate.

[0014] Preferably, a second docking plate is fixedly connected to the top of the rotating seat at the end away from the height measuring rod body.

[0015] Preferably, both the first and second mating plates have through holes on their surfaces.

[0016] Preferably, a bolt is fitted into both through holes, and a hexagonal nut is threaded onto one end of the bolt that passes through the through hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] By incorporating a connecting rod and a sleeve, workers measure the specific height of trees using the height-measuring rod itself. The sleeve is then positioned close to the top of the tree. Compared to directly observing the top of the height-measuring rod, the sleeve is at an angle to the eye, facilitating alignment with the tree's top. After the height-measuring rod extends to the tree's designated growth height, if the tree's top is higher than the sleeve, it meets the growth specifications; if the top is lower, it does not. After adjusting the sleeve's height once, workers do not need to retract it; they can simply move the height-measuring rod in its output state to the next sapling for direct height measurement. The sleeve design facilitates tree measurement, significantly increasing efficiency and solving the problem of existing tree height measurement devices being unable to perform batch testing on multiple trees.

[0025] This application provides a tree growth height measuring device, which effectively solves the problem that existing tree growth height measuring devices are difficult to use for batch testing of multiple trees.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing tree height measurement devices are difficult to use for batch testing of multiple trees. The overall idea is as follows:

[0028] To address the problems existing in the prior art, this utility model provides a tree growth height measuring device, including a height measuring rod body 1, with scales 2 on the surface of the height measuring rod body 1, a rotating seat 3 fixedly connected to the output end of the height measuring rod body 1, a pin 4 rotatably connected to the end of the rotating seat 3 away from the height measuring rod body 1, and a marking mechanism fixedly connected to the rotating seat 3 through the pin 4. The marking mechanism is used to assist the user in observing the specific height of the top of the height measuring rod body 1. The marking mechanism includes a connecting rod 5, a sleeve rod 7 slidably connected to one end of the connecting rod 5, and a clamping bolt 6 threadedly connected to the top of the connecting rod 5 near the sleeve rod 7.

[0029] The end of connecting rod 5 furthest from sleeve rod 7 is inserted into pin 4.

[0030] The end of the connecting rod 5 away from the sleeve rod 7 is fixedly connected to the first mating plate 8.

[0031] The top of the rotating seat 3, away from the height measuring rod body 1, is fixedly connected to a second docking plate 9.

[0032] Both the first docking plate 8 and the second docking plate 9 have through holes on their surfaces.

[0033] A bolt 11 is fitted into both through holes, and a hexagonal nut 10 is threaded onto one end of the bolt 11 that passes through the through hole.

[0034] The height measuring rod body 1 is the main body for measuring height, and the surface is marked with scale 2 for reading the height.

[0035] Scale 2 is set on the surface of the height measuring rod body 1 to indicate the measured height value.

[0036] The rotating base 3 is fixed to the output end of the height measuring rod body 1 and is used to connect and support the rotation of the marking mechanism.

[0037] The pin 4 is used to rotatably connect the rotating seat 3 to the marking mechanism, so that the marking mechanism can rotate around the rotating seat 3.

[0038] Link 5 is a component of the marking mechanism. One end is inserted into pin 4, and the other end is slidably connected to sleeve 7, serving as a connection and support.

[0039] The clamping bolt 6 is threaded onto the top of the connecting rod 5 near the end of the sleeve rod 7, and is used to fix the position of the sleeve rod 7 on the connecting rod 5.

[0040] The sleeve 7 is slidably connected to one end of the connecting rod 5 and is telescopic. It is used to help users observe the specific height of the top of the height measuring pole body 1 and to facilitate alignment with the top of the tree.

[0041] The first docking plate 8 is fixed at the end of the connecting rod 5 away from the sleeve rod 7, and cooperates with the second docking plate 9 to fix the position of the connecting rod 5 after it is unfolded.

[0042] The second docking plate 9 is fixed on the top of the rotating seat 3 at the end away from the height measuring rod body 1, and cooperates with the first docking plate 8 to fix the position of the connecting rod 5 after it is unfolded.

[0043] The hexagonal nut 10 and the bolt 11 are used to fix the first mating plate 8 and the second mating plate 9 together.

[0044] Bolt 11 passes through the through holes of the first mating plate 8 and the second mating plate 9, and is fixed in place by cooperating with hexagonal nut 10.

[0045] Working principle:

[0046] The first step, according to this application, is to unfold the connecting rod 5 to a position parallel to the rotating seat 3, and align and fit the first docking plate 8 and the second docking plate 9. The first docking plate 8 and the second docking plate 9 are fixed by bolts 11 and hexagonal nuts 10. The sleeve rod 7 can extend and retract inside the connecting rod 5, and the clamping bolt 6 is used to fix the sleeve rod 7.

[0047] The second step, in this application, involves setting up a connecting rod 5 and a sleeve rod 7. Workers measure the specific height of a tree using the height measuring rod body 1, and then bring the sleeve rod 7 close to the top of the tree. Compared to directly observing the top of the height measuring rod body 1, observing the sleeve rod 7 at a certain angle to the human eye facilitates alignment with the tree's top. After the height measuring rod body 1 extends to the tree's prescribed growth height (the height a tree should reach under natural growth conditions within a certain time; if it does not reach the standard, the tree may have growth problems), if the tree's top is higher than the sleeve rod 7, it meets the growth specifications; if the tree's top is lower than the sleeve rod 7, it does not meet the growth specifications. After adjusting the height of the sleeve rod 7 once, workers do not need to retract it; they can directly move the height measuring rod body 1 in its output state to the area below the next sapling to directly measure the tree's height. Because the sleeve rod 7 facilitates tree measurement, it significantly increases measurement efficiency.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
