Description

Technical Field

[0001] This utility model belongs to the technical field of tree measuring equipment, specifically relating to a tree crown width measuring device. Background Technology

[0002] The crown width of a tree refers to the average width of the tree in the north-south and east-west directions. It is commonly used to indicate tree size and serves as a reference standard for measuring tree growth. In landscape design, crown width is used to calculate the number of trees planted per square meter. Crown width is one of the important measurement indicators for measuring each tree in forest survey plots and is also an important parameter for scientific research. Therefore, it is necessary to measure the crown width of trees using a crown width measuring device.

[0003] However, the existing method for changing the measurement direction from east-west to north-south in the use of tree crown width measurement devices usually involves moving the entire measurement device and then repositioning, setting up, and leveling it. The measurement operation requires repeated moving and positioning operations, making the overall measurement work cumbersome, time-consuming, and labor-intensive.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a tree crown width measuring device to solve the problem that the measurement operation requires constant movement of the measuring equipment and repeated positioning, making the overall measurement work cumbersome, time-consuming and labor-intensive.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] A tree crown width measuring device includes two ring bodies and several pressure blocks. Each ring body comprises two identical semi-rings that interlock. Each ring body has a sliding groove. A spring connects each ring body to a pressure block. A slider is slidably mounted between the two ring bodies. A locking bolt is rotatably mounted on the top of the slider. A level compass is fixedly mounted on the top of the slider. A measuring tape is fixedly mounted on the slider. A positioning component is provided on the top of the measuring tape. The positioning component includes a mounting frame, a laser pointer, and a counterweight ball. The mounting frame is fixedly mounted on the measuring tape. A first ring is hinged to the mounting frame. A second ring is hinged to the first ring. A mounting plate is hinged to the second ring. The laser pointer is vertically mounted on the mounting plate.

[0008] Based on the above technical solution, the present invention has made the following improvements:

[0009] Furthermore, the measuring tape has a handle at the bottom of its head; the handle provides a stable gripping area for the operator, making it easy to operate by hand, and making it more convenient, faster and more accurate to adjust the angle and orientation, thus helping to improve measurement efficiency.

[0010] Furthermore, a laser rangefinder is fixedly installed on the top of the measuring tape; after the measuring tape is pulled out and aligned with the outermost edge of the tree canopy by the positioning component, the laser rangefinder is activated to emit a laser to obtain measurement data, which is then calibrated with the scale of the measuring tape to avoid errors caused by a single measurement and improve the accuracy of the measurement.

[0011] Furthermore, an adjusting rod is provided at the bottom of the ring. By inserting the adjusting rod into the ground, the entire measuring device can be firmly fixed, preventing the ring from shifting due to spring twisting during rapid pulling of the measuring tape, which could lead to measurement errors. This ensures stable positioning of the entire device and improves data reliability. Simultaneously, the height of the adjusting rod is adjustable, facilitating adjustment of the insertion depth.

[0012] Furthermore, the bottom of the adjusting rod is tapered; this structural design is simple, adaptable to complex terrain, and can be quickly inserted into the ground, improving the convenience of the device.

[0013] The beneficial effects of this utility model are as follows: The ring body and pressure spring structure with a pair of semi-ring interlocking rings can quickly adapt to different tree trunk diameters and provide stable fixation, reducing debugging time and improving the versatility of the device; the slider and the horizontal compass work together to quickly and accurately lock onto various measurement positions, avoiding the inefficiency caused by repeatedly moving the entire device when changing measurement directions; the multi-axis rotation design in the positioning component, combined with the counterweight ball, enables the mounting frame to self-balance, allowing the laser pointer to quickly project the laser onto any edge point of the tree canopy and maintain a vertical reference, eliminating the need for manual leveling, which helps reduce measurement errors and solves the problem of the measurement operation requiring constant movement of the entire measuring device and repeated positioning, making the overall measurement work cumbersome, time-consuming, and labor-intensive.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 4 As shown, a tree crown width measuring device includes two ring bodies 1 and several pressure blocks 2. Each ring body 1 comprises two identical semi-rings that interlock. Each ring body 1 has a sliding groove 3. Springs 4 connect each ring body 1 to the pressure blocks 2. The pressure blocks 2 are pressed against the tree trunk, and then the springs 4 are compressed to engage the semi-rings. Under the action of the springs 4, the pressure blocks 2 clamp the tree trunk, and the device is installed on the tree trunk. A slider 5 is slidably installed between the ring bodies 1. A locking bolt 6 is rotatably installed on the top of the slider 5, and a horizontal compass 7 is fixedly installed on the top of the slider 5. By sliding the slider 5 directly on the sliding groove 3 and using the compass in the horizontal compass 7 on the top of the slider 5, the measurement direction can be quickly and accurately adjusted. Then, the locking bolt 6 is rotated for rapid positioning. A measuring tape 8 is fixedly mounted on the slider 5. A positioning component 9 is located at the top of the measuring tape 8. The positioning component 9 includes a mounting frame 91, a laser pointer 95, and a counterweight ball 96. The mounting frame 91 is fixedly mounted at the top of the measuring tape 8. A first ring 92 is hinged to the mounting frame 91 via a first pivot 99. A second ring 93 is hinged to the first ring 92 via a second pivot 98. A mounting plate 94 is hinged to the second ring 93 via a third pivot 97. The first pivot 99 and the third pivot 97 are coaxial. The laser pointer 95 is vertically mounted on the mounting plate 94. Through the three-dimensional rotation of the first pivot 99, the second pivot 98, and the third pivot 97, and with the counterweight ball 96, gravity automatically keeps the mounting plate 94 horizontal, ensuring that the laser beam of the laser pointer 95 is projected vertically. This avoids beam tilting caused by human factors, which could affect measurement accuracy. The measurement personnel then use the vertical beam as a standard to measure the crown width of the tree canopy.

[0022] Specifically, the measuring tape 8 has a handle 12 at the bottom of its tip; the handle 12 provides a stable gripping area for the operator, making it easy to operate by hand, and making it more convenient, faster and more accurate to adjust the angle and orientation, which helps to improve the efficiency of measurement.

[0023] Specifically, a laser rangefinder 13 is fixedly installed on the top of the measuring tape 8. After the measuring tape 8 is pulled out and aligned with the outermost edge of the tree canopy by the positioning component 9, the laser rangefinder 13 is activated to emit a laser and obtain measurement data. This structural design and the scale behavior of the measuring tape 8 are calibrated from two sources to avoid errors in the measurement data caused by a single measurement and improve the accuracy of the measurement.

[0024] Specifically, the bottom of the ring 1 is provided with an adjusting rod 15. By setting the adjusting rod 15, after the adjusting rod 15 is inserted into the ground, the entire measuring device can be firmly fixed, avoiding the problem of the measuring tape 8 being pulled out quickly and the spring 4 twisting, causing the ring 1 to shift and resulting in measurement data errors. This facilitates the stable positioning of the entire device and improves the reliability of the data. At the same time, the height of the adjusting rod 15 is adjustable, making it easy to adjust the insertion depth.

[0025] Specifically, the bottom of the adjusting rod 15 is tapered; this structural design is simple, can adapt to complex terrain, can be quickly inserted into the ground, and improves the convenience of the device.

[0026] The method of using this utility model is as follows: First, insert the adjusting rod 15 into the ground and adjust the height of the device. Then, fasten a pair of half rings around the tree to form a ring body 1, and compress the spring 4 after the pressure block 2 is attached to the tree trunk. Use the elastic force of the spring 4 to clamp and fix the device to the tree trunk. Then, slide the slider 5 on the slide groove 3. Then, pass the other pair of half rings through the slider 5 and fasten them around the tree trunk. Use the level compass 7 to ensure that the device is in a horizontal reference state. During measurement, slide the slider 5 along the groove 3 on the ring 1, determine the target measurement orientation using the horizontal compass 7 at the top of the slider 5, and fix the position of the slider 5 by rotating the locking bolt 6; pull out the measuring tape 8, move it by holding the handle 12 at the bottom of the tape head, and achieve self-balancing of the mounting plate 94 through the combined action of the first rotating shaft 99, the second rotating shaft 98, the third rotating shaft 97 and the counterweight ball 96 in the positioning assembly 9, so that the beam of the vertically placed laser pointer 95 on the mounting plate 94 can be projected vertically, avoiding the beam tilt caused by human factors from affecting the measurement accuracy. Then, the measuring personnel use the vertical beam as a standard to measure the crown width of the tree crown, and at the same time turn on the laser rangefinder 13, and then take readings for both the measuring tape 8 and the laser rangefinder 13 to complete the measurement.
