Description

Technical Field

[0001] This application relates to the technical field of forestry surveying, and more specifically, to a forestry field surveying instrument. Background Art

[0002] A forestry field surveying instrument is an important device that can accurately and efficiently measure forestry areas, which can reduce the workload of surveyors and improve the accuracy of measurement results. It is widely used in forestry surveying. However, the field environment is complex and changeable, and the cooperative installation of the surveying instrument and the tripod cannot stably support its use, resulting in inconvenient exploration.

[0003] The prior art document with the publication (announcement) number CN221280268U provides a forestry field surveying instrument. In the related technology of this device, the stability of support is improved through a support component, which can adapt to soft muddy ground, avoid subsidence and inclination, effectively improve the stability, and prevent errors in measurement data. Secondly, through the protection component, it is convenient to store and protect the main body of the surveying instrument, avoiding the cumbersome steps of repeated disassembly and installation, saving time and effort, greatly improving the detection efficiency, and enhancing the practicability of the surveying instrument.

[0004] Although the above prior art solution can achieve the related beneficial effects through the structure of the prior art, there are still the following defects: the inserted rod inserted into the soil layer has no anti - detachment structure. The sliding sleeve with elastic abutment forms a reverse force with the inserted rod inserted into the soil layer under the elastic support of the spring, resulting in unstable connection between the inserted rod and the soil layer.

[0005] In view of this, we propose a forestry field surveying instrument. Utility Model Content

[0006] To improve the problems raised in the above background art, this application provides a forestry field surveying instrument.

[0007] The forestry field surveying instrument provided by this application adopts the following technical solutions:

[0008] A forestry field surveying instrument includes:

[0009] A protection cylinder, a ground cone rod, a side rod assembly and an elastic pressing plate;

[0010] The protection cylinder is fixedly installed at one end of the ground cone rod;

[0011] The side rod assembly includes a fixed sleeve plate fixedly installed outside the ground cone rod. A plurality of floor - sticking plates are hinged and installed outside the fixed sleeve plate in an annular equidistant structure. One side of the floor - sticking plate is hinged with a side support rod. A sliding sleeve seat is hinged and installed between the plurality of side support rods. The sliding sleeve seat is elastically slidably matched with the ground cone rod sleeved with a spring member;

[0012] The elastic pressing plate is fixedly connected inside the through opening on one side of the sliding sleeve seat and is engaged with the groove formed on the outer part of the ground cone rod.

[0013] By adopting the above technical solution, the ground cone rod is inserted into the soil layer, the floor tile is abutted against the ground, and the side support rod hinged on one side is used to push the sliding sleeve seat to move upward and be limited, squeezing the spring member to be elastically compressed. The elastic pressing plate installed in the displaced sliding sleeve seat is engaged with the groove formed on the outer part of the ground cone rod, so as to fix the position of the sliding sleeve seat and ensure the stability of the connection and limit between the ground cone rod and the soil layer.

[0014] As an alternative solution of the technical solution of this application document, the ground cone rod is fixedly connected by two parts, namely an insertion rod and a hollow cylinder. An activity groove is formed inside the insertion rod. A convex platform shaft is slidably connected inside the activity groove. A plurality of inclined grooves are formed on the outer part of the convex platform shaft. A nail rod is slidably connected inside the inclined grooves. The nail rod is slidably matched inside the insertion rod. One end of the convex platform shaft provided with an external thread groove is threadedly adapted to the hollow cylinder.

[0015] By adopting the above technical solution, when the convex platform shaft and the hollow cylinder are adjusted by threads, the displaced convex platform shaft squeezes the insertion rod to be limited and extended, increasing the firmness of the connection between the ground cone rod and the soil layer and ensuring the stability of the connection between the ground cone rod and the soil layer.

[0016] As an alternative solution of the technical solution of this application document, the nail rod is arranged in an inclined structure.

[0017] By adopting the above technical solution, by arranging the nail rod in an inclined structure, it can be ensured that the nail rod and the soil layer form a barbed structure, realizing the stability of the connection between the nail rod and the soil layer.

[0018] As an alternative solution of the technical solution of this application document, a column body is fixedly connected to one end of the floor tile.

[0019] By adopting the above technical solution, the column body can ensure that the turning action is smoother when the floor tile presses on the soil layer surface.

[0020] As an alternative solution of the technical solution of this application document, a pull ring rod is fixedly connected to one side of the elastic pressing plate.

[0021] By adopting the above technical solution, the pull ring rod can realize the convenience of stretching and adjusting the elastic pressing plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this application, the ground cone rod is inserted into the soil layer, the floor plate is abutted against the ground, and the side support rod installed by hinge on one side pushes the sliding sleeve seat to move upward in a limited manner, squeezing the spring member for elastic compression.

Detailed Description of the Embodiment

[0031] The following further describes this application in detail with reference to the drawings of the specification.

[0032] Refer to Figures 1-5 , in a forestry field measuring instrument recorded in the embodiment of this application, a forestry field measuring instrument includes: a protective cylinder 1, a ground cone rod 2, a side rod assembly 3 and an elastic pressing plate 4;

[0033] The protective cylinder 1 is fixedly installed at one end of the ground cone rod 2;

[0034] The side lever assembly 3 includes a fixed sleeve plate 31 fixedly installed outside the ground cone rod 2. A plurality of floor plates 32 are hingedly installed outside the fixed sleeve plate 31 in an annular equidistant structure. One side of the floor plate 32 is hingedly installed with a side support rod 33. A sliding sleeve seat 34 is hingedly installed between the plurality of side support rods 33. The sliding sleeve seat 34 is elastically slidably matched with the ground cone rod 2 sleeved with a spring member. One end of the floor plate 32 is fixedly connected with a cylinder 35;

[0035] The elastic pressing plate 4 is fixedly connected in the through hole on one side of the sliding sleeve seat 34 and is clamped and matched with the groove opened on the outside of the ground cone rod 2.

[0036] For this forestry field measuring instrument, by inserting the ground cone rod 2 into the soil layer, the floor plate 32 abuts against the ground, and the side support rod 33 hingedly installed on one side is used to push the sliding sleeve seat 34 to move upward in a limited manner, squeezing the spring member for elastic compression. The elastic pressing plate 4 installed in the displaced sliding sleeve seat 34 is clamped and matched with the groove opened on the outside of the ground cone rod 2, realizing the position fixation of the sliding sleeve seat 34, ensuring the stability of the insertion and limit of the ground cone rod 2 and the soil layer, and the floor plate 32 can shield the outside of the ground cone rod 2, ensuring the safety of the ground cone rod 2 during use.

[0037] Refer to Figure 2 and Figure 3 In the forestry field measuring instrument described in the embodiment of the present application, the ground cone rod 2 is fixedly connected by two parts, namely an insertion rod 21 and a hollow cylinder 22. An activity groove is opened inside the insertion rod 21. A boss shaft 23 is slidably connected in the activity groove. A plurality of inclined grooves are opened on the outside of the boss shaft 23. A nail rod 24 is slidably connected in the inclined grooves. The nail rod 24 is slidably matched inside the insertion rod 21. One end of the boss shaft 23 with an external thread groove is threadedly adapted to the hollow cylinder 22, and the nail rod 24 is arranged in an inclined structure.

[0038] For this forestry field measuring instrument, when the boss shaft 23 is threadedly adjusted with the hollow cylinder 22, the displaced boss shaft 23 squeezes the insertion rod 21 to extend outwards in a limited manner, increasing the firmness of the connection between the ground cone rod 2 and the soil layer, ensuring the stability of the connection between the ground cone rod 2 and the soil layer. The nail rod 24 arranged in an inclined structure can ensure that the nail rod 24 and the soil layer form a barbed structure, realizing the stability of the connection between the nail rod 24 and the soil layer.

[0039] Refer to Figure 5 and Figure 1 In the forestry field measuring instrument described in the embodiment of the present application, a pull ring rod 41 is fixedly connected to one side of the elastic pressing plate 4.

[0040] For this forestry field measuring instrument, the convenience of stretching and adjusting the elastic pressing plate 4 can be realized by using the pull ring rod 41.

[0041] Working principle: When using this device to insert and limit the support with the soil layer, the operator first manually turns out one of the floor attachments 32. At this time, the turned-out floor attachment 32 pushes the laterally supported rod 33 installed by hinge to lift the sliding sleeve seat 34, and squeezes the spring member sleeved outside the ground cone rod 2 for elastic pressing;

[0042] When the sliding sleeve seat 34 is displaced, the multiple laterally supported rods 33 installed by hinge outside it will all pull out and expand the floor attachment 32, exposing the conical end of the ground cone rod 2;

[0043] Then, insert the ground cone rod 2 into the soil layer. The floor attachment 32 is in close contact with the ground, and pushes the sliding sleeve seat 34 to rise to an appropriate height. The elastic pressing plate 4 fixedly installed in the sliding sleeve seat 34 is then clamped and limited with the groove opened outside the ground cone rod 2 to ensure the stability of the connection between the ground cone rod 2 and the soil layer;

[0044] Finally, rotate the boss shaft 23 clockwise to be thread-fitted with the hollow cylinder 22. The upwardly moving boss shaft 23 squeezes the nail rod 24 that is slidably fitted outside to be limited and extended, improving the firmness of the connection between the ground cone rod 2 and the soil layer. Then, open the measuring device in the protective cylinder 1 to conduct measurement.
