Description

Technical Field

[0001] The invention belongs to the technical field of tree measurement, and in particular relates to a forestry tree measuring device. Background Art

[0002] Arboretum measurement is an activity that involves measuring various parameters and characteristics of trees or forests. These measurements can be used for a variety of purposes, including forestry management, ecological protection, urban planning, environmental monitoring, etc. When conducting tree measurements, measurement equipment is required.

[0003] A Chinese patent (CN117968487B) discloses a forestry tree measuring device, which relates to the technical field of measuring tools. The device comprises a graduated rod, an installation block being provided at the end of the graduated rod, an internal rotation of which is connected to a drive column, and one end of each of the two drive columns being fixedly connected to a flip rod. Through the coordinated use of the flip rod, the measuring rod, the measuring belt, and the extension plate, during measurement, the two flip rods are controlled to rotate, thereby separating the two measuring rods further and further apart to determine the approximate width of the tree. When the distance between the two measuring rods is greater than the diameter of the tree, the two measuring rods are clamped on both sides of the tree, and the motor is started to rotate in the opposite direction to clamp the two measuring rods on the tree. Therefore, even if the distance between trees in the forest is very small, as long as the space on both sides of the tree is greater than the diameter of the measuring rod, it can be measured. At the same time, there are not many restrictions on the measuring environment. Secondly, the measuring device is in a standing pole state in the initial state, so it is extremely convenient to carry or transport. Although current tree measuring devices can measure trees, when measuring the horizontal spacing between trees, the ground in the measurement area is not necessarily level, resulting in angular deviations in the measurement structure and errors in the measurement data. At the same time, when measuring tree height using lasers, measurement errors can also occur due to different levels of the ground. The actual application effect of the equipment is not good. Therefore, a forestry tree measuring device is proposed. Summary of the Invention

Furthermore, when measuring tree height using lasers, measurement errors may also occur due to differences in ground levelness, resulting in poor practical application of the equipment. The present invention proposes a forestry tree measuring device.

Since the adjustment component is provided with a longer power arm, the height measuring component can be operated with relatively little effort, and during the adjustment process of the height measuring component, the support plate can be deflected to a certain extent under the action of multiple upper springs, so that the support roller rolls on the bottom surface of the mounting shell, while giving the mounting shell a certain supporting force, further reducing the difficulty of operating the height measuring component.

[0044] The spacing measuring assembly 6 includes a bracket 65, which is fixedly mounted on the top surface of the base 4. A main scale 61 is rotatably mounted on the inner side of the bracket 65 via a rotating shaft. Both ends of the main scale 61 are provided with multi-stage receiving teeth 62. A mounting frame 64 is fixedly mounted on the bottom of the main scale 61. A lead cake 63 is fixedly mounted on the inner side of the mounting frame 64. The lead cake 63 is located on the longitudinal center axis of the main scale 61.

[0045] The height measuring assembly 8 includes a mounting shell 81, which is rotatably mounted on the inner side of the mounting slot 7 via a rotating shaft. An arc-shaped gear cover 82 is fixedly mounted on one end of the mounting shell 81, and a guard plate 86 is provided at the other end of the mounting shell 81. An adjusting motor 83 is fixedly mounted on an inner wall of one side of the mounting shell 81, and an adjusting stud 84 is fixedly mounted on one end of the output shaft of the adjusting motor 83. A laser altimeter 85 is mounted on the external thread of the adjusting stud 84. The laser altimeter 85 is slidably connected to the inner walls on both sides of the mounting shell 81. A wiping pad is provided inside the mounting shell 81, and the wiping pad is located on one side of the laser altimeter 85.

[0046] The specific implementation method is as follows: when measuring the horizontal spacing between trees, the device is directly moved to the measurement area, placed in the middle position between the trees to be measured, and the movable wheel 3 is locked. At this time, the main ruler 61 can always maintain a horizontal state under the action of the lead cake 63 at its bottom, and the multi-step storage teeth 62 are pulled to both sides until the two multi-step storage teeth 62 are respectively attached to the side wall surfaces of the two trees. The vertical on the two multi-step storage teeth 62 is recorded, and the length interval of the main ruler 61 is added to obtain the spacing between the two trees. Even if the ground in the measurement area is uneven, it will not affect the measurement accuracy of the device. At the same time, when measuring the height of the trees, the height measurement component 8 is driven to deflect to a suitable angle. At this time, the angle of the height measurement component 8 with the horizontal direction can be observed through the angle scale disk 2. If the base 4 is in a tilted state, the angle scale disk 2 can be directly rotated so that the angle scale disk 2 and the main ruler 61 are parallel to each other, and accurate angle data can be obtained.

[0047] Through this design, the distance between trees and the height of trees can be measured. Even if the device is in an uneven measurement area, accurate measurement data can be obtained, which greatly reduces the measurement deviation caused by different environments and improves the actual application effect of the equipment.

[0048] The adjusting assembly 5 includes a connecting rod 54, which is rotatably mounted on an outer wall of one side of the base 4. The connecting rod 54 is fixedly connected to one end of a rotating shaft arranged on an outer wall of one side of the mounting shell 81. A power arm 52 is fixedly mounted on one end of the connecting rod 54, and a handle 51 is provided on the top of the power arm 52. A mounting hole is provided inside the connecting rod 54, and a positioning pin 53 is slidably installed in the mounting hole. One end of the positioning pin 53 is embedded in the inside of the positioning hole 12.

[0049] The leveraging support assembly 9 includes a support plate 94, which is rotatably mounted on the inner side of the mounting groove 7 via a rotating shaft. Two side frames 92 are fixedly mounted on one end of the support plate 94, and a support roller 91 is rotatably mounted between the two side frames 92 via a rotating shaft. The support roller 91 is rollingly connected to the bottom surface of the mounting shell 81, and a plurality of top springs 93 are fixedly mounted on the bottom surface of the support plate 94. The bottom ends of the plurality of top springs 93 are fixedly mounted in top holes provided on the top surface of the mounting groove 7.

[0050] The specific implementation method is as follows: when the device is measuring the height of a tree, the guard plate 86 is opened, the adjustment motor 83 is turned on, and the adjustment stud 84 is rotated, thereby controlling the lateral movement of the laser altimeter 85. The wiping pad can clean the laser emission area of ​​the laser altimeter 85. Finally, the laser altimeter 85 is guided out and emits a laser. The power arm 52 is moved by the handle 51, driving the connecting rod 54 to rotate synchronously, thereby driving the height measurement component 8 to deflect, so that the laser emitted by the laser altimeter 85 is exactly located at the top of the tree. The distance data is recorded, and then the horizontal distance between the device and the tree and the deflection angle of the height measurement component 8 can be used to automatically calculate the height of the tree. Since the adjustment component 5 is provided with a long power arm 52, the height measurement component 8 can be operated with relatively little effort. During the adjustment process of the height measurement component 8, the support plate 94 can be deflected to a certain extent under the action of multiple upper springs 93, so that the support roller 91 rolls on the bottom surface of the mounting shell 81, while providing the mounting shell 81 with a certain supporting force, further reducing the difficulty of operating the height measurement component 8.

[0051] Through this design, not only can the deflection angle of the laser altimeter 85 be manually adjusted to ensure the accuracy of the angle adjustment of the laser altimeter 85, but it can also greatly reduce the difficulty of manually adjusting the angle of the laser altimeter 85, saving time and effort, and greatly improving the convenience of using the equipment.

[0052] The positioning assembly 10 includes an engaging tooth plate 102, and a guide rail is fixedly installed on the inner wall of the mounting groove 7. The engaging tooth plate 102 is slidably installed on the guide rail through the limiting sliding grooves 104 arranged on both sides thereof. The engaging tooth plate 102 and the arc-shaped tooth cover 82 are meshed and connected with each other. Two spring bottom shafts 103 are fixedly installed on the bottom surface of the engaging tooth plate 102, and one end of the two spring bottom shafts 103 passes through and extends to the outside of the base 4. The bottom ends of the two spring bottom shafts 103 are fixedly installed with a positioning base plate 101, and an anti-slip pad is provided on the bottom surface of the positioning base plate 101. There is rotation damping between the angle ruler disk 2 and the top groove.

[0053] The specific implementation method is as follows: when the angle of the height measuring component 8 is adjusted, the arc-shaped tooth cover 82 will also rotate synchronously. When the arc-shaped tooth cover 82 rotates, it can drive the meshing tooth plate 102 engaged with it to move downward, thereby synchronously driving the two spring bottom shafts 103 to move downward, thereby driving the positioning base plate 101 to move downward. At this time, the positioning base plate 101 can come into contact with the ground, thereby giving the device another support contact surface when the movable wheel 3 is locked, thereby further improving the stability of the device, avoiding unnecessary displacement when adjusting the height measuring component 8, and further improving the actual application effect of the device.

[0054] Working principle: When measuring the horizontal spacing between trees, directly move the device to the measurement area, place the device in the middle position between the trees to be measured, lock the movable wheel 3, and the main ruler 61 can always maintain a horizontal state under the action of the lead cake 63 at its bottom. Pull the multi-step storage teeth 62 to both sides until the two multi-step storage teeth 62 respectively fit the side wall surfaces of the two trees, record the vertical on the two multi-step storage teeth 62, and add the length interval of the main ruler 61 to obtain the spacing between the two trees. Even if the ground in the measurement area is uneven, it will not affect the measurement accuracy of the device. At the same time, when measuring the height of the trees, drive the height measurement component 8 to deflect to a suitable angle. At this time, the angle of the height measurement component 8 with the horizontal direction can be observed through the angle scale disk 2. If the base 4 is in a tilted state, the angle scale disk 2 can be directly rotated so that the angle scale disk 2 and the main ruler 61 are parallel to each other, and accurate angle data can be obtained.

[0055] When the device is measuring the height of a tree, the guard plate 86 is opened, the adjustment motor 83 is turned on, and the adjustment stud 84 is rotated, thereby controlling the lateral movement of the laser altimeter 85. The wiping pad can clean the laser emission area of ​​the laser altimeter 85. Finally, the laser altimeter 85 is guided out and emits a laser. The power arm 52 is moved by the handle 51 to drive the connecting rod 54 to rotate synchronously, thereby driving the height measurement component 8 to deflect, so that the laser emitted by the laser altimeter 85 is exactly located at the top of the tree, and the distance data is recorded. Then, the horizontal distance between the device and the tree and the deflection angle of the height measurement component 8 can be used to automatically calculate the height of the tree. Since the adjustment component 5 is provided with a long power arm 52, the height measurement component 8 can be operated with relatively little effort. In addition, during the adjustment process of the height measurement component 8, the support plate 94 can be deflected to a certain extent under the action of multiple upper springs 93, so that the support roller 91 rolls on the bottom surface of the mounting shell 81, while providing the mounting shell 81 with a certain supporting force, further reducing the difficulty of operating the height measurement component 8.

[0056] When the angle of the height measuring component 8 is adjusted, the arc-shaped tooth cover 82 will also rotate synchronously. When the arc-shaped tooth cover 82 rotates, it can drive the meshing tooth plate 102 engaged with it to move downward, thereby synchronously driving the two spring bottom shafts 103 to move downward, thereby driving the positioning base plate 101 to move downward. At this time, the positioning base plate 101 can come into contact with the ground, thereby giving the device another supporting contact surface when the movable wheel 3 is locked, thereby further improving the stability of the device, avoiding unnecessary displacement when adjusting the height measuring component 8, and further improving the actual application effect of the device.
