Description

Technical Field

[0001] This invention belongs to the field of forestry afforestation tools technology, and in particular relates to a circular afforestation laser positioning instrument. Background Technology

[0002] In forestry afforestation operations, circular, clustered, and ring-shaped afforestation layouts are widely used in scenarios such as barren mountain ecological restoration and large-scale economic forest planting due to their advantages such as good ventilation and light penetration, uniform tree growth space, and ease of later management. However, currently, the industry still uses traditional methods such as manually pulling lines, measuring distances with tape measures, and inserting tags to mark the planting sites for this type of afforestation layout. This method has many technical shortcomings: Firstly, the manual measurement and marking method is extremely inefficient. A single person can only locate a small number of afforestation sites per day, which cannot meet the needs of large-scale afforestation. Secondly, manual operation is prone to visual and measurement errors, resulting in uneven spacing between trees and rows in the planting holes and irregular circumferential distribution, which in turn affects the later growth of trees and reduces the survival rate and quality of the forest stand. Third, most of the existing afforestation positioning tools are structured to suit square grid afforestation, such as positioning rulers and grid frames, which are difficult to adapt to the requirements of circular and clump-shaped afforestation layouts. Moreover, most of the tools are large and heavy, making them difficult to move and operate in complex terrains such as mountains and slopes. Fourth, the traditional marking method of inserting tags is easily affected by factors such as wind and loose soil, which can cause the tags to shift, further reducing the accuracy of the planting location and leading to problems such as missed planting and uneven planting.

[0003] In summary, the industry urgently needs a specialized afforestation positioning tool that can adapt to circular afforestation layouts, provide precise positioning, be easy to operate, be highly efficient, and be adaptable to complex terrains. This tool would address the technical shortcomings of traditional manual positioning methods and existing tools, thereby improving the standardization and scale of circular afforestation operations. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a circular afforestation laser positioning instrument to solve the problems of low efficiency, poor accuracy and inconvenient operation in traditional circular afforestation acupoint positioning. It realizes one-time synchronous and accurate marking of circular afforestation acupoints, improves the efficiency and positioning accuracy of afforestation operations, and is suitable for the operation needs of complex terrains such as mountains and slopes.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: A circular afforestation laser positioning device includes a central positioning component, a circular base, a retractable positioning rod component, a radius adjustment mechanism, and a laser positioning component; The central positioning component is fixedly connected to the center of the lower surface of the disk base; The telescopic positioning rod assembly is provided in five sets. The five sets of telescopic positioning rod assemblies are evenly distributed at an angle of 72° along the radial direction of the disc base. The telescopic positioning rod assembly includes an outer tube and an inner rod. One end of the outer tube is fixed to the edge of the disc base, and the inner rod is slidably disposed inside the outer tube. The radius adjustment mechanism includes a locking component located at the connection between the outer tube and the inner rod, and a length scale engraved on the surface of the inner rod. The laser positioning assembly includes laser units installed at the ends of five inner rods furthest from the outer tube, with the laser emission direction of each laser unit perpendicular to the ground. When the five laser units are activated simultaneously, they can create five evenly distributed afforestation site markers on the ground, centered on the central rod and with a radius equal to the extension length of the positioning rod. The laser units are connected to the inner rods via a threaded, detachable connection, allowing for individual removal and replacement of damaged laser units, thus reducing instrument maintenance costs.

[0006] Furthermore, the center positioning component includes a central rod fixed to the center of the lower surface of the disk base. The end of the central rod away from the disk base is a pointed conical structure, which is used to vertically insert into the ground to form a reference center. The length of the central rod is 1m.

[0007] Furthermore, the surface of the conical structure of the central rod is hardened by quenching to a hardness ≥ HRC45, which enhances the wear resistance and soil penetration ability of the central rod and prevents bending and wear when used in hard soil.

[0008] Furthermore, the locking component is a set screw or snap-fit ​​structure used for positioning and locking after the inner rod extends or retracts. The length scale has a measurement range of 1m to 2m, enabling precise adjustment of the extension length of the positioning rod. The length scale on the surface of the inner rod has a graduation value of 1cm, allowing for fine adjustment of the extension length of the positioning rod and meeting the precise design requirements of different afforestation row and plant spacings.

[0009] Furthermore, an integrated operating handle is fixedly connected to the center of the upper surface of the disc base for carrying, moving, and fixing the instrument.

[0010] Furthermore, the outer surface of the operating handle is covered with an anti-slip rubber sleeve, and the surface of the rubber sleeve is provided with anti-slip texture to improve the grip stability during manual operation and prevent the hand from slipping.

[0011] Furthermore, the outer tube and inner rod of the disc base and the telescopic positioning rod assembly are both made of aluminum alloy. The overall structure is lightweight and has impact and corrosion resistance, making it suitable for afforestation operations in complex terrains such as mountains, slopes, and wastelands.

[0012] Furthermore, the laser device is a high-brightness point laser emitting structure with a laser spot diameter ≤5mm, ensuring the positioning accuracy of afforestation site marking. The laser device is powered by a rechargeable lithium battery, which can work continuously for ≥8 hours on a single charge.

[0013] The circular laser afforestation positioning instrument provided by this invention has the following advantages compared with the prior art: 1. Significantly improved work efficiency: This invention uses five sets of laser instruments to emit lasers simultaneously, which can accurately mark five circular afforestation holes at once. The work efficiency is 5 to 10 times higher than the traditional manual line measurement method. A single person can complete the location of thousands of afforestation holes in a single day, meeting the needs of large-scale afforestation. 2. High positioning accuracy: The retractable positioning rod assembly of the present invention is engraved with a length scale of 1cm division value, the laser spot diameter of the laser instrument is ≤5mm, and the five sets of positioning rods are evenly distributed along the circumference at 72°, which effectively avoids visual errors and distance measurement errors caused by manual operation, ensuring that the spacing between trees and rows of afforestation holes is uniform and the circumferential distribution is regular, with a positioning accuracy of ≤5mm, thereby improving the survival rate of afforestation and the quality of forest stands; 3. High adaptability: The whole structure is made of aluminum alloy, which is lightweight and sturdy. The pointed conical structure of the central rod is hardened by quenching, which can adapt to various complex afforestation terrains such as mountains, slopes, wastelands, and hard soils. A single person can complete the entire operation without the need for additional auxiliary tools. 4. Easy to operate and low maintenance cost: The radius adjustment of the instrument is achieved by locking and adjusting quickly through locking parts. The operation process is simple and can be mastered without professional skills. The laser unit and the inner rod are connected by a threaded detachable connection. If the laser unit is damaged, it can be disassembled and replaced separately without replacing the whole instrument, which greatly reduces maintenance costs. Attached Figure Description

[0014] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0015] Figure 1 This is a schematic diagram of the structure of the present invention; Figure 2 This is a top view of the present invention.

[0016] In the diagram: 1-Disc base, 2-Retractable positioning rod assembly, 3-Laser instrument, 4-Center rod, 5-Operating handle. Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1 refer to Figure 1-2 As shown, the present invention provides a circular afforestation laser positioning instrument, including a central positioning component, a circular base 1, a retractable positioning rod component 2, a radius adjustment mechanism, and a laser positioning component; The center rod 4 of the center positioning component is made of aluminum alloy, is 1m long, and has a pointed conical structure at the lower end that has been hardened by quenching to a hardness of HRC45. It can be easily inserted into hard soil in mountainous areas to form a reference center. The disc base 1 is an aluminum alloy circular disc with a diameter of 30cm. A 20cm long integrated aluminum alloy operating handle 5 is fixed to the center of the upper surface. The outer surface of the handle is covered with a 5mm thick anti-slip rubber sleeve with diamond-shaped anti-slip texture on the surface of the rubber sleeve. The retractable positioning rod assembly 2 consists of five sets, evenly distributed at a radial angle of 72° along the disc base 1. The outer tube of each set is an aluminum alloy sleeve with a length of 1m, and the inner rod is an aluminum alloy round rod with a length of 1m. The inner rod can extend and retract along the axial direction of the outer tube, with an extension range of 0 to 1m. Combined with the length of the outer tube, the overall extension length of the positioning rod is 1m to 2m. More preferably, the retractable positioning rod assembly 2 is rotatably connected to the disc base 1 and has a certain damping. When not in use, the five sets of retractable positioning rod assemblies 2 can be folded toward the central rod 4, thereby saving space.

[0018] The locking component of the radius adjustment mechanism is a set screw structure, which is located at the free end of the outer tube. By rotating the set screw, the inner rod can be locked and fixed to the outer tube. The inner rod has length graduations on its surface, with a measurement range of 1m to 2m and a graduation value of 1cm. The laser positioning component's laser unit 3 is a high-brightness point laser emitting structure with a laser spot diameter of 3mm. The laser unit 3 is detachably connected to the free end of the inner rod via an M8 thread. The laser unit 3 is powered by a 3.7V rechargeable lithium battery with a capacity of 2000mAh, which can work continuously for 10 hours on a single charge.

[0019] Example 2

[0020] The difference between this embodiment and Embodiment 1 is that: The locking element is a snap-fit ​​structure, located at the connection between the outer tube and the inner rod. Pressing the snap-fit ​​allows for quick extension and locking of the inner rod, making operation more convenient. The laser spot diameter of the laser instrument 3 is 5mm. It is powered by a 5V rechargeable lithium battery with a capacity of 1500mAh, and can work continuously for 8 hours on a single charge. The anti-slip rubber sleeve of the operating handle 5 has striped anti-slip texture, and the hardness of the conical structure of the center rod 4 is HRC50, which makes it more capable of penetrating the soil.

[0021] Method of using the present invention

[0022] S1: With the reference point fixed, the operator holds the operating handle 5 and aligns the conical structure of the center rod 4 vertically with the reference point of the afforestation plot. The center rod 4 is then forcefully inserted into the soil to ensure that the disc base 1 is horizontal and the instrument is stable and does not shake. S2: Positioning radius adjustment. According to the spacing requirements of the afforestation design, loosen the locking device and pull the inner rod along the axial direction of the outer tube. According to the length scale on the surface of the inner rod, adjust the positioning rod to the specified extension length. After adjustment, tighten the set screw or press the buckle to lock the inner rod and the outer tube in place. S3: Laser acupoint marking. Turn on the power switch of laser device 3. Five laser devices 3 simultaneously emit lasers perpendicular to the ground downwards, forming five evenly distributed laser spots on the ground with the central rod 4 as the center and the length of the positioning rod extension as the radius. These spots are the precise marking points for afforestation acupoints. S4: Cyclic operation. After completing a set of acupoint markings, the operator holds the operating handle 5 and pulls the central rod 4 out of the soil, moves the instrument to the next afforestation benchmark point, and repeats steps S1-S3 to achieve standardized and precise positioning of circular afforestation acupoints for the entire forest area.
