Description

Technical Field

[0001] This utility model belongs to the field of shrub diameter measurement technology, and in particular relates to a portable shrub diameter measurement device for forestry surveys. Background Technology

[0002] Shrub diameter measurement is a measurement method used in the field of landscaping to evaluate the thickness of shrub seedlings or low shrubs. It refers to the diameter at a specific height close to the ground. The diameter is often used to measure the thickness of seedlings or low shrubs as an indicator of vitality. The larger the diameter, the stronger the vitality of the seedling and the higher the survival rate.

[0003] Currently, most shrub diameter measurement devices are integrated units that cannot be disassembled or folded. As a result, when some parts of the measuring device need to be repaired or replaced, the entire device needs to be transported to a repair shop, which leads to low repair efficiency and can easily reduce measurement efficiency.

[0004] To address this issue, we propose a portable shrub diameter measuring device for forestry surveys. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that when some parts of the measuring equipment need to be repaired or replaced, the entire device needs to be transported to a repair shop, resulting in low repair efficiency and a reduction in measurement efficiency. Therefore, this invention proposes a portable shrub diameter measuring device for forestry surveys.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A portable shrub diameter measuring device for forestry surveys includes a mechanical claw. A fixed inclined plate is fixedly connected to the outer surface of the mechanical claw. A fixed cylinder is fixedly connected to the outer surface of the fixed inclined plate. Two grooves are formed on the outer surface of the fixed cylinder. An adjusting rod is engaged inside each groove. Several identical limiting holes are formed on the outer surface of each adjusting rod. Two electric telescopic rods are fixedly connected inside the mechanical claw. A buffer base is fixedly connected to the telescopic end of each electric telescopic rod. A push handle is fixedly connected to the outer surface of each adjusting rod. A first locking block and a second locking block are jointly provided on the outer sides of the two adjusting rods. A fixed rod is fixedly connected to the outer surface of the first locking block. A support plate is fixedly connected to the top of the fixed rod. A control panel is fixedly connected to one side of the support plate.

[0007] Preferably, a reinforcing plate is fixedly connected to the outer surface of the fixed cylinder, and the outer surface of the reinforcing plate is fixedly connected to the outer surface of the fixed inclined plate.

[0008] Preferably, the inner wall of the reinforcing plate is threaded with four first fixing bolts, and the outer surface of each set of first fixing bolts is in contact with the inner wall of the reinforcing plate.

[0009] Preferably, a dustproof shell is fixedly connected to the outer surface of each of the electric telescopic rods, and the outer surface of each dustproof shell is fixedly connected to the outer surface of the mechanical claw.

[0010] Preferably, a limiting rod is engaged inside a set of limiting holes, and the outer surface of the limiting rod is in contact with the inner wall of the fixed cylinder.

[0011] Preferably, the outer surface of the limiting rod is threaded with two first limiting nuts, and the side of the two first limiting nuts that are close to each other is in contact with the outer surface of the fixing cylinder. The inner wall of the first locking block and the inner wall of the second locking block are threaded with two second fixing bolts, and the outer surface of each second fixing bolt is threaded with a second limiting nut.

[0012] Preferably, a limiting plate is fixedly connected to the outer surface of the fixing rod, and the upper surface of the limiting plate is fixedly connected to the bottom surface of the support plate.

[0013] Preferably, the inner wall of the limiting plate is threaded with two limiting bolts, and the outer surface of each limiting bolt is threadedly connected to the inner wall of the support plate.

[0014] In summary, the technical effects and advantages of this utility model are as follows: 1. By setting up a combination of "first locking block + second locking block + second fixing bolt + second limit nut" to connect the support plate and the adjusting rod, the support plate and the adjusting rod can be separated by unscrewing the second limit nut and the second fixing bolt. The adjusting rod is locked in the fixed cylinder through a groove. The adjusting rod can be taken out of the fixed cylinder by pulling out the limit rod. This enables the rapid disassembly of core components such as mechanical claw, fixed cylinder, adjusting rod, and support plate. When a local part fails, the faulty component can be disassembled and transported for maintenance without having to carry the whole set of equipment, reducing transportation costs and time, avoiding interruption of measurement work due to overall equipment maintenance, and significantly improving maintenance efficiency and measurement continuity. 2. By setting a limit rod to engage with the limit holes at different positions, the length of the adjustment rod extending out of the fixed tube can be freely adjusted. This not only adapts to close-range measurement of low shrubs, but also avoids the inconvenience caused by operators bending over or leaning too close. Furthermore, the components are detachable and smaller in size, making them easy to pack into a transport box and carry. This solves the problem of traditional integrated equipment being "large in size and difficult to transport", and is suitable for mobile measurement needs in complex outdoor terrains such as mountains and forests.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A portable shrub diameter measuring device for forestry surveys includes a mechanical claw 1, a fixed inclined plate 2 fixedly connected to the outer surface of the mechanical claw 1, a fixed cylinder 3 fixedly connected to the outer surface of the fixed inclined plate 2, and a reinforcing plate 10 fixedly connected to the outer surface of the fixed cylinder 3. The outer surface of the reinforcing plate 10 is fixedly connected to the outer surface of the fixed inclined plate 2. The reinforcing plate 10 can reinforce the fixed cylinder 3 and the fixed inclined plate 2 to prevent them from shaking during use.

[0019] Two grooves 7 are formed on the outer surface of the fixed cylinder 3. An adjusting rod 4 is snapped into the inside of each groove 7. Four first fixing bolts 11 are threadedly connected to the inner wall of the reinforcing plate 10. The outer surface of each set of first fixing bolts 11 is in contact with the inner wall of the reinforcing plate 10. The position of the reinforcing plate 10 can be restricted by the first fixing bolts 11, which can play the role of fixing and limiting.

[0020] Each adjusting rod 4 has several identical limiting holes 6 on its outer surface. The mechanical claw 1 has two electric telescopic rods 22 fixedly connected inside. Each electric telescopic rod 22 has a dustproof shell 21 fixedly connected to its outer surface. The outer surface of each dustproof shell 21 is fixedly connected to the outer surface of the mechanical claw 1. The dustproof shell 21 can protect the electric telescopic rod 22 and prevent external dust and impurities from interfering with it.

[0021] Each electric telescopic rod 22 has a buffer base 23 fixedly connected to its telescopic end, and each adjusting rod 4 has a push handle 15 fixedly connected to its outer surface. A set of limiting holes 6 are connected to a limiting rod 8. The outer surface of the limiting rod 8 is in contact with the inner wall of the fixed cylinder 3. The limiting rod 8 can play a fixed and limiting role, thereby enhancing the stability of the device.

[0022] The outer sides of the two adjusting rods 4 are jointly provided with a first locking block 13 and a second locking block 14. A fixing rod 16 is fixedly connected to the outer surface of the first locking block 13. Two first limiting nuts 9 are threadedly connected to the outer surface of the limiting rod 8. The side of the two first limiting nuts 9 that are close to each other is in contact with the outer surface of the fixing cylinder 3. Two second fixing bolts 19 are threadedly connected to the inner wall of the first locking block 13 and the inner wall of the second locking block 14. A second limiting nut 20 is threadedly connected to the outer surface of each second fixing bolt 19. The position of the limiting rod 8 can be restricted by the first limiting nut 9. The position of the first locking block 13 and the second locking block 14 can be fixed and restricted by the second fixing bolts 19 and the second limiting nut 20, thereby enhancing the applicability of the device.

[0023] A support plate 5 is fixedly connected to the top of the fixed rod 16, and a limiting plate 17 is fixedly connected to the outer surface of the fixed rod 16. The upper surface of the limiting plate 17 is fixedly connected to the bottom surface of the support plate 5. The limiting plate 17 can reinforce the fixed rod 16 and the support plate 5 to prevent them from swaying during use.

[0024] A control panel 12 is fixedly connected to one side of the support plate 5. Two limit bolts 18 are threadedly connected to the inner wall of the limit plate 17. The outer surface of each limit bolt 18 is threadedly connected to the inner wall of the support plate 5. The position of the limit plate 17 can be fixed by the limit bolts 18, which further prevents the fixing rod 16 from shaking.

[0025] The working principle of this utility model is as follows: When in use, if the length of the initially assembled adjustment rod 4 cannot be adapted to the current shrub, such as if there are weeds blocking the shrub, and it is necessary to extend the adjustment rod 4 to avoid the obstruction, the first limit nuts 9 at both ends of the limit rod 8 can be unscrewed counterclockwise, the limit rod 8 can be pulled out, the adjustment rod 4 can be pushed along the groove 7, and its extension length can be adjusted. Then, the limit hole 6 that is aligned can be re-selected and inserted into the limit rod 8, and the first limit nut 9 can be tightened to complete the second length adjustment. The electric telescopic rod 22 can be started by the "calibration" button on the control panel 12, so that the electric telescopic rod 22 drives the buffer base 23 to retract to the shortest state. At this time, the two gripping arms of the mechanical claw 1 are at the maximum opening angle, which makes it easy to fit into the bottom of the shrub later. When performing measurements, the operator holds the push handle 15 on the outer surface of the adjusting rod 4 with both hands, aligns the opening gripping arm of the mechanical claw 1 with the measurement position of the shrub "close to the ground at a specific height", and slowly moves the device to center the shrub branch in the mechanical claw 1 to avoid measurement errors caused by branch deviation. Press the "Measurement Start" button on the control panel 12, and the electric telescopic rod 22 will extend slowly after being powered on, driving the buffer base 23 to descend and stabilize the entire device. When the mechanical claw 1 contacts the surface of the shrub branch, the control panel 12 will display a "Clamping in place" prompt. At this time, the mechanical claw 1 stops closing. The high-precision sensor inside the mechanical claw 1, such as the pressure-sensitive diameter sensor, automatically collects the circumference or diameter data of the shrub's ground diameter after clamping in place and transmits the data to the control panel 12. The display screen of the control panel 12 shows the measurement in real time. The operator can save the data to the built-in memory of the panel through the "Save" button or transmit it to an external device via Bluetooth to complete the ground diameter measurement of a single shrub. After the measurement is completed, press the "Reset" button, the mechanical claw 1 will open, and the device can be moved to measure the next shrub.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
