Description

Technical Field

[0001] This utility model relates to the field of forestry tool technology, specifically a forestry survey marking tool with telescopic function. Background Technology

[0002] In forestry resource surveys, ecological monitoring, afforestation planning, and timber harvesting supervision, marking tools are core equipment for accurate positioning, boundary demarcation, and information recording. Their ease of use and adaptability directly affect survey efficiency and data accuracy. Currently, commonly used marking tools in forestry surveys mainly include fixed-length markers, spray paint cans, measuring tapes, and ordinary marking pens. These tools have significant limitations in complex forest environments. Traditional tools lack flexible length adjustment capabilities, requiring surveyors to frequently change tools when marking quadrat boundaries, tree row spacing, or terrain inflection points with different intervals. Furthermore, existing marking tools have relatively limited functionality, mostly only capable of basic location marking, making it difficult to meet the integrated needs of forestry surveys.

[0003] A search revealed existing technology (application number: CN202023071366.8), which describes "a field marker pole for forestry ecological surveys." This utility model discloses a field marker pole for forestry ecological surveys, comprising a ground stake and a protective device. A connecting plate is fixedly connected to the surface of the ground stake, and a connecting rod is rotatably connected to the top of the ground stake. A protective device is provided at the end of the connecting rod away from the ground stake. The protective device includes a connecting block, the bottom of which engages with the connecting rod. A receiving groove is formed on the surface of the connecting block, and sliders are slidably connected to both side walls of the receiving groove. A first spring is fixedly connected to the top of each of the two sliders. A base plate is rotatably connected to the side of the two sliders closest to each other. A fixing clip is fixedly installed on the surface of the base plate, and marking paper is clamped inside the fixing clip. A pull ring is rotatably connected to the end of the base plate away from the slider. A transparent plastic plate, matching the size of the receiving groove, is fixedly installed on the surface of the connecting block. Two insert rods are slidably inserted into the bottom of the connecting block.

[0004] However, while existing technologies have improved the lifespan of marking paper, enhanced marking stability and protection, and improved the ease and flexibility of operation, thus addressing the problems of easy damage and inconvenient adjustment of traditional marking poles, they still have some shortcomings: the height adjustment function is missing, as different vegetation at different growth stages or different terrain environments require different heights; and while they only have marking functions, additional tools are still needed for surveying.

[0033] In this embodiment, the sampling component and the marking component constitute a forestry survey marking tool with a telescopic function according to this application.

[0034] Understandable, Figure 1 This illustration only schematically shows some components of a forestry survey marker tool with telescopic functionality. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a forestry survey marking tool with scalable functionality can also include features compared to... Figure 1 More or fewer parts.

[0035] It should also be understood that the measuring ruler 10, the lighting lamp 18, and the Velcro 19 were all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] The side cover 4 is provided with a magnetic strip at the contact point with the inner wall of the tool housing 1, which serves as a brake when closed. It is not shown in the figure, and any commercially available one can be used.

[0037] Furthermore, in this embodiment, the tool housing 1 is made of metal and is cylindrical; the rear cover 2 is made of engineering plastic and is cylindrical, with a handle at the other end made of rubber; the rotating plate 6 is made of engineering plastic and is circular; the telescopic rod 11 is made of aluminum alloy and is cylindrical; the foot pedal 16 is made of aluminum alloy and is rectangular; the lighting base 17 is made of engineering plastic and is block-shaped; the telescopic component controls the telescopic rod 11 to slide along the groove of the tool housing 1, adjusting the overall length of the tool; the marking component is used for marking survey points; the measuring component realizes distance measurement; the lighting component provides illumination in low-light environments; the foot pedal 16 facilitates fixing or inserting the tool into the ground using foot strength; integrating telescopic, marking, measuring, and lighting functions, it is suitable for complex forestry survey environments, improving survey efficiency and convenience.

[0038] Specifically, the storage cylinder 3 is threaded onto the rear cover 2 at one end and is located in a cylindrical groove at one end of the tool housing 1. The interior is hollow and the opening faces the rear cover 2.

[0039] In this embodiment, the storage cylinder 3 is made of engineering plastic and is cylindrical. The storage cylinder 3 can be easily put in and taken out by unscrewing the back cover 2 through the thread. After storage, it can be connected to the back cover 2 and then installed back into the groove of the tool housing 1 to achieve sealed storage. It provides a portable storage space for the sample after sampling, avoids loss, and improves the integration of the tool.

[0040] Specifically, the sampling tube 20 is fixedly installed at one end on the telescopic rod 11 away from the tool housing 1 via a connecting column, and the other end is provided with a cylindrical groove and a through groove on the outer wall.

[0041] As a preferred implementation method, the sampling tube 20 is made of stainless steel and is cylindrical. The telescopic rod 11 is extended to a suitable length, the sampling tube 20 is aligned with the collection point, and the tool is pressed or rotated to insert the sampling tube 20 into the sampling. After the sample enters the cylindrical groove, the tool is pulled out to complete the collection. The long groove can be used to observe the sample volume and can also be used to clean up residual samples after collection, realizing the rapid collection of small samples such as soil and bark in forestry surveys. The structure is simple and easy to operate.

[0042] Example 2:

[0043] Based on Example 1, in order to further realize sampling and exploration and facilitate subsequent marking, a marking component and a measuring component are arranged in a groove on one side of the outer wall of the tool housing 1;

[0044] Specifically, the marking components include: a side cover 4, one end of which is rotatably mounted on the inner wall of a long groove on one side of the tool housing 1 via a pin, and the other end of which is provided with a pull plate; and a marking flag 5, which is set in a long groove on one side of the tool housing 1, one end of which is provided with a conical drill block, and the other end of which is provided with a marking flag 5, for a total of two sets.

[0045] In this embodiment, the side cover 4 is made of engineering plastic and is in the shape of an arc plate; the marking flag 5 consists of a plastic flag surface and a metal rod; by pulling the pull plate of the side cover 4, the long slot is opened, the marking flag 5 is taken out, the conical drill block is aligned with the survey marking point, and the metal rod is pressed or tapped to insert the marking flag 5 into the ground to complete the marking; when it is necessary to retrieve the marking after the marking is completed, the marking flag 5 is pulled out and put back into the long slot, the side cover 4 is closed, and the survey point marking is completed quickly. The colored flag surface has high recognition and is convenient for subsequent positioning and review.

[0046] Specifically, the measuring components include: a rotating shaft 7, which is through and fixedly mounted on the rotating plate 6; a rotating base 8, which is fixedly mounted on one end of the rotating shaft 7 and rotatably mounted in the groove of the tool housing 1; a torsion spring 9, which is mounted on one side of the rotating shaft 7, with one end fixedly connected to the rotating plate 6 and the other end fixedly connected to the rotating base 8; and a measuring ruler 10, which is wound around and mounted on the other side of the rotating shaft 7, with one end fixedly mounted on the rotating shaft 7 and the other end provided with a limiting piece.

[0047] With this setup, the rotating base 8 is made of engineering plastic and is cylindrical; the torsion spring 9 is made of spring steel; and the measuring ruler 10 is a fiber tape measure. Pulling the limiting plate of the measuring ruler 10 causes the tape measure to unfold from the rotating shaft 7, allowing measurement of the distance between survey points or the growth diameter of trees. After measurement, releasing the limiting plate resets the torsion spring 9, causing the rotating shaft 7 to rotate and retract the tape measure, which is then wound around the rotating shaft 7. This enables rapid short-distance measurement without the need to carry an additional tape measure, improving the tool's practicality.

[0048] Example 3:

[0049] Based on Example 1, in order to accommodate different users and sampling depths, a telescopic component is arranged on one side of the telescopic rod 11.

[0050] Specifically, the telescopic assembly includes: a brake plate 12, which is fixedly installed on one end of the telescopic rod 11 near the rear cover 2, and has a cylindrical groove on one side; a first spring 13, which is installed in the groove on the same side as the brake plate 12 on the tool housing 1, with one end fixedly connected to the brake plate 12 and the other end fixedly connected to the inner wall of the groove on the tool housing 1; a sliding block 14, which is slidably installed in the cylindrical groove on the brake plate 12; and a second spring 15, which is installed in the cylindrical groove on the brake plate 12, with one end fixedly connected to the inner wall of the brake plate 12 and the other end fixedly connected to the sliding block 14.

[0051] The brake plate 12 is made of aluminum alloy and is circular in shape. The first spring 13 and the second spring 15 are both made of spring steel. The sliding block 14 is made of engineering plastic, with one side cylindrical and the other side hemispherical. Pressing the sliding block 14 compresses the second spring 15, causing the sliding block 14 to disengage from the positioning groove of the tool housing 1. At this time, the telescopic rod 11 can be pulled and slid along the groove of the tool housing 1 to the required length. Releasing the sliding block 14 causes the second spring 15 to reset and push the sliding block 14 into the corresponding positioning groove, fixing the position of the telescopic rod 11. The first spring 13 assists in buffering and resetting the telescopic rod 11 when it extends, realizing the rapid adjustment and locking of the tool length to adapt to different survey scenarios.

[0052] Specifically, the lighting components include: a light lamp 18, which is installed in the semi-circular groove of the lighting base 17 via Velcro 19; one end of the Velcro 19 is fixedly installed on one side of the lighting base 17, and the other end is attached to the other side of the lighting base 17.

[0053] In this embodiment, the lighting lamp 18 is a high-intensity LED lamp; when lighting is needed, the switch of the lighting lamp 18 is turned on, and the LED lamp illuminates the survey area; when lighting is not needed, the switch is turned off; if replacement or charging is required, the lighting lamp 18 can be removed by tearing off the Velcro 19, and after the operation is completed, it can be fixed back by the Velcro 19, which solves the lighting needs in low light environments during forestry surveys. The Velcro fixing method facilitates the disassembly and maintenance of the lamp body; when it is necessary to send signals for communication, the lighting lamp 18 can be used to emit signals directly through light by shaking, which is convenient to operate.

[0054] In actual use, when lighting is needed, the user can attach the lighting lamp 18 to the telescopic rod 11 via Velcro 19, or remove the lighting lamp. After selecting a sampling site, the user can use the tool to sample. The extension of the telescopic rod 11 can be adjusted according to the user's comfort or the sampling depth. Press the sliding block 14 and pull the sampling tube 20 to make the telescopic rod 11 slide in the groove of the tool housing 1. After sliding to the required length, the sliding block 14 will pop out of the groove on the outer wall of the tool housing 1 under the action of the second spring 15. After sampling, the back cover 2 can be rotated off and the storage tube 3 can be rotated off to collect the sampled soil. When surveying forests, the measuring ruler 10 can be pulled to measure the diameter of trees and other plants. After the survey, when marking is needed, the side cover 4 can be pulled to take out the marking flag 5 in the groove and temporarily fix the marking flag 5 to the marking location through the sharp end.

[0055] The lighting 18 can also be other types of lighting to provide convenient illumination in low light conditions. It is not limited to high-intensity LED lights, as long as it can provide reconnaissance lighting and transmit communication signals through light.

[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
