Description

Technical Field

[0001] This utility model belongs to the field of tree surveying technology, specifically relating to a device for surveying tree diameter at breast height (DBH) and height. Background Technology

[0002] Diameter at breast height (DBH) and tree height are key indicators for measuring standing tree growth and important attributes of forest resource surveys. Traditional methods for measuring DBH mainly involve direct measurement using measuring tapes, diameter measuring tapes, and calipers; traditional methods for measuring tree height mainly involve direct measurement using Brewles height gauges. The entire measurement process is labor-intensive, prone to errors, and inefficient due to manual data reading and recording, severely restricting the efficiency and quality of forest resource surveys.

[0003] For example, a Chinese patent discloses a measuring device for measuring the diameter at breast height (DBH) and height of trees (publication number CN216385472U), which includes: a body, a DBH measuring mechanism, the DBH measuring mechanism being mounted on the body and used to measure the DBH of trees, and a distance measuring mechanism, the distance measuring mechanism being mounted on the body.

[0004] However, in the aforementioned publicly available documents, measuring the diameter at breast height (DBH) of trees generally requires pulling the rope end to wrap the rope around the tree and press it against the tree's surface. After measurement, the rope end is released, and the reel automatically retracts the rope. However, in practice, because the reel with the rope end automatically retracts the rope, continuous pulling of the rope end is necessary, increasing the workload for the user. Furthermore, during surveying, the user must simultaneously handle the machine and the rope end, making further rope adjustments impossible, thus requiring assistance from another person and increasing personnel deployment. Therefore, those skilled in the art have provided a tree DBH and height measurement device to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to provide a tree diameter at breast height (DBH) and height measurement device that can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A tree diameter at breast height (DBH) and height surveying device includes a body, a height measuring component is provided on the top surface and left end of the body, a DBH measuring component is provided on the left end of the bottom surface of the body, a handle is fixedly installed on the right end of the bottom surface of the body, a square plate is fixedly connected to the bottom surface of the handle, and a clamping component is provided on the left outer wall of the square plate.

[0008] The diameter at breast height (DBH) measuring assembly includes a chamber fixed to the left end of the outer bottom surface of the machine body by bolts. A rotating shaft is rotatably mounted inside the chamber. A rope wheel is fixedly sleeved on the outer wall of the rotating shaft. A rope for measuring the DBH of trees is wound around the outer wall of the rope wheel. A limiting tube that penetrates the chamber is fixed to the front outer wall of the chamber. One end of the rope passes through the limiting tube and extends to the front outer wall of the chamber, where a rope head is fixed. A positioning tube that penetrates the chamber is fixed to the rear outer wall of the chamber.

[0009] The present invention is further configured such that: the clamping assembly includes a U-shaped sleeve fixed to the left outer wall of the square plate by bolts, a second rotating shaft is symmetrically mounted inside the U-shaped sleeve, a connecting block is fixedly sleeved on the outer wall of the two second rotating shafts, and a clamping plate with an arc groove is fixed on the left outer wall of each of the two connecting blocks.

[0010] The present invention is further configured such that: the interior of both clamping plates is provided with an arc-shaped ring, and threaded rods are rotatably connected to the opposite outer walls of the two arc-shaped rings, with the opposite ends of the two threaded rods respectively threaded to the opposite outer walls of the two arc-shaped rings, and a knob is fixed to the outer wall; and several locking teeth are fixed to the inner walls of the two arc-shaped rings.

[0011] The present invention is further configured such that: one end of each of the two rotating shafts extends to the outer top surface of the U-shaped sleeve, and gears are fixed on the outer wall of each shaft, the two gears being meshed; and the other end extends to the outer bottom surface of the U-shaped sleeve, and a knob is fixed on the outer wall of one of the rotating shafts.

[0012] This utility model is further configured such that the outer wall dimensions of the rope head and the inner wall dimensions of the positioning tube are mutually compatible.

[0013] This utility model is further configured such that one end of the rotating shaft extends rotatably to the outer bottom surface of the chamber body and is fixed with a knob.

[0014] The technical effects achieved by this utility model are as follows:

[0015] 1. This utility model relates to a tree diameter at breast height (DBH) and height measurement device. By using a positioning square tube, the rope can be wrapped around and fitted to the tree, and then locked with the rope end. This prevents the rope from retracting on its own, thus avoiding the need to continuously pull the rope end, reducing the workload of the user, and improving practicality.

[0016] 2. The tree diameter at breast height and height surveying device designed in this paper, through the interaction of the rotating shaft, gear and knob, can drive two clamps to open and close. Then, the combined action of the arc ring, threaded rod and knob can limit and lock the device to the tree, avoiding the problem that the user cannot adjust the rope while picking up the machine body and the rope end at the same time, thus further improving the practicality.

[0025] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-3 As shown, a tree diameter at breast height (DBH) and height surveying device includes a body 1. A height measuring component 2 is provided on the left end of the outer top surface of the body 1. The height measuring component 2 can use a laser ranging component or an ultrasonic height measuring component to measure the height of the tree.

[0027] A diameter at breast height (DBH) measuring assembly 3 is provided on the left end of the outer bottom surface of the machine body 1. The DBH measuring assembly 3 includes a chamber 301 fixed to the left end of the outer bottom surface of the machine body 1 by bolts. The threaded connection facilitates disassembly, replacement, and maintenance. A rotating shaft 302 is rotatably mounted inside the chamber 301. A rope pulley 303 is fixedly sleeved on the outer wall of the rotating shaft 302. A rope 304 for measuring the DBH of trees is wound around the outer wall of the rope pulley 303. A limiting square tube 305, which is interconnected with the chamber 301, is fixed to the front outer wall of the chamber 301. The rope... One end of 304 extends through the limiting square tube 305 to the front outer wall of the storage body 301 and is fixed with a rope head 306. When the user pulls the rope head 306, the rope wheel 303 sleeved on the rotating shaft 302 can rotate smoothly, thereby releasing the rope 304 from the inside of the storage body 301. At the same time, a displacement actuator can be installed on the rope wheel 303 or the limiting square tube 305, so that when the rope head 306 is pulled to pull the rope 304 from the inside of the storage body 301 and wrap it around the tree, the diameter at breast height of the tree can be accurately measured.

[0028] A positioning square tube 307, which is interconnected with the storage unit 301, is fixed to the rear outer wall of the storage unit 301. The outer wall dimensions of the rope end 306 and the inner wall dimensions of the positioning square tube 307 are matched. One end of the rotating shaft 302 extends to the outer bottom surface of the storage unit 301 and is fixed with a knob 308. After the rope 304 is pulled out from inside the storage unit 301 and wrapped around the tree once, the rope end 306 is inserted into the inside of the positioning square tube 307 to fix the rope 304. Then, the knob 308 is turned to... The rotating shaft 302 is driven to rotate in the opposite direction, which in turn drives the rope wheel 303 to retract the rope 304, thereby causing the rope 304 to adhere to the surface of the tree. At the same time, the rotating shaft 302 is a damping shaft, which can self-lock after rotation, thus ensuring that the final measurement data is relatively accurate. After the measurement is completed, the rope end 306 is taken out from the inside of the positioning square tube 307, and then the knob 308 is turned to retract the rope 304 onto the rope wheel 303. The operation is simple and convenient.

[0029] A handle 101 is fixedly installed on the right end of the outer bottom surface of the machine body 1. A square plate 102 is fixedly connected to the outer bottom surface of the handle 101. A clamping component 4 is provided on the left outer wall of the square plate 102. When the user holds the handle 101, the clamping component 4 on the square plate 102 can be placed between the two outer sides of the tree. The clamping component 4 includes a U-shaped sleeve 401 fixed to the left outer wall of the square plate 102 by bolts. The threaded connection facilitates disassembly, replacement and maintenance in the future. Rotating shafts 402 are symmetrically rotated inside the U-shaped sleeve 401. Connecting blocks 403 are fixedly sleeved on the outer walls of the two rotating shafts 402. Clamping plates 404 with arc grooves are fixed on the left outer walls of the two connecting blocks 403. One end of the two rotating shafts 402 extends to Gears 409 are fixed on the top and outer walls of the U-shaped sleeve 401. The two gears 409 are meshed. The other end extends to the bottom surface of the U-shaped sleeve 401. A knob 410 is fixed on the outer wall of one of the rotating shafts 402. Turning the knob 410 drives one of the rotating shafts 402 to rotate one of the gears 409. Due to the meshing connection of the gears 409, the other gear 409 drives the other rotating shaft 402 to rotate synchronously, thereby realizing the opening and closing effect of the clamping plate 404, which is convenient for clamping trees. Then, the shaft locking device installed on the bottom surface of the U-shaped sleeve 401 locks one of the rotating shafts 402 to prevent it from spinning and affecting the subsequent clamping effect.

[0030] Both clamping plates 404 have an arc-shaped ring 405 inside. Threaded rods 406 are rotatably connected to the opposite outer walls of the two arc-shaped rings 405. The opposite ends of the two threaded rods 406 extend threadedly to the opposite outer walls of the two arc-shaped rings 405, and a knob 407 is fixed to the outer wall. Several locking teeth 408 are fixed to the inner walls of the two arc-shaped rings 405. When the diameter at breast height (DBH) of the tree to be measured is different, the knob 407 can be turned to drive the threaded rods 406 to rotate. With the assistance of the guide rods set between the arc-shaped rings 405 and the clamping plates 404, the arc-shaped rings 405 are pushed to move back and forth, thus allowing the two arc-shaped rings 405 to move back and forth. 05. The device interlocks with the outer walls of trees of different sizes (after the threaded rod 406 pushes the arc ring 405 to fit against the tree, the threaded rod 406 is locked by the shaft locking device installed on the outer wall of the clamping plate 404, ensuring the stability of the clamping). At the same time, the frictional resistance between the arc ring 405 and the tree is increased by the action of the locking teeth 408, which allows the device to be clamped onto the tree to be measured. Thus, the rope 304 can be pulled around the tree without the assistance of others, and the problem of the user being unable to adjust the rope 304 while holding the machine body 1 and the rope end 306 is avoided, further improving the practicality.

[0031] The working principle of this utility is as follows: When in use, the user quickly picks up the machine body 1 by holding the handle 101, then finds a relatively flat outer wall of the tree to be measured, and then turns the knob 410 to drive the rotating shaft 402 to rotate, so that the connecting block 403 can achieve the opening and closing effect of the clamping plate 404.

[0032] Simultaneously, by turning the knobs in sequence, the threaded rod 406 is rotated, which in turn pushes the arc-shaped ring 405 to move, so that the two arc-shaped rings 405 engage with the outer wall of the tree, allowing the device to be attached to the tree to be measured.

[0033] At the same time, the user pulls the rope end 306 to make the rope wheel 303 rotate on the rotating shaft 302 to achieve the unwinding effect of the rope 304. After the rope 304 is wrapped around the tree once, the rope end 306 is inserted into the inside of the positioning square tube 307 to fix the rope 304.

[0034] Next, turn knob 308 to drive rotating shaft 302 to rotate in the opposite direction, causing rope wheel 303 to retract with rope 304, so that rope 304 fits against the surface of the tree, ensuring that the final measurement data is more accurate. After the measurement is completed, rope 304 can be retracted into the chamber 301.

[0035] Finally, the height of the tree is measured using height measurement component 2.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
