[0002] In the process of forest resource survey, a variety of precision instruments are needed for data collection and analysis, such as tree height measuring instruments, vegetation density measuring instruments, soil sample collectors, etc. However, there are many shortcomings in the existing forest resource survey instruments and their mounting brackets, which seriously affect the efficiency and accuracy of the survey work. First, the existing mounting brackets are difficult to use under complex forest terrain conditions, such as slopes, swamps, etc., and the traditional fixing method is difficult to ensure the stability and reliability of the equipment. Secondly, these instruments are easily affected by external environmental factors, such as strong light may cause equipment overheating or sensor failure, and rainfall may cause water damage to the equipment, resulting in data distortion or equipment failure. In addition, the existing mounting brackets have poor applicability and cannot be adjusted in height according to the height of different users, which limits the versatility and comfort of the equipment.

[0043] Through the above scheme: the rotation of the transmission screw 60 is controlled by the No. 3 forward and reverse motor 59, and then the extension length of the supporting slide bar 55 is adjusted, so that the ground nails 57 on the base plate 56 can be firmly inserted into the ground, which not only ensures the stability of the entire device under various terrain conditions, but also can quickly adjust the height of the device to adapt to different ground conditions. The operation is simple and fast, and no manual adjustment is required, which greatly reduces the installation time and labor intensity and improves work efficiency.

[0044] In this embodiment, the marking mechanism 6 includes a powder box 61, and four clamping columns 62 used in conjunction with the clamping holes 12 are fixedly installed on the upper end of the powder box 61. The powder box 61 is detachably installed on the lower end of the support sleeve 1 through the four clamping columns 62. A feeding trough 63 is provided in the middle of the upper end of the powder box 61, and a plurality of discharge troughs 65 are provided in a circular array at the lower end of the powder box 61.

It can not only flexibly adjust the opening and closing of the mark as needed to ensure the clarity and accuracy of the mark, effectively avoid investigators from getting lost in complex terrain, and increase safety, but also allow users to choose different powder types according to different marking requirements. It is suitable for a variety of survey and marking scenarios, such as vegetation surveys, terrain measurements, etc.

[0046] In the specific use process of this embodiment, first, start the No. 3 forward and reverse motor 59, the output end of the No. 3 forward and reverse motor 59 drives the transmission screw 60 to rotate, and the transmission screw 60 is threadedly connected with the transmission block 551 on the outer surface of the support slide 55, so the rotation of the transmission screw 60 will drive the support slide 55 to slide in the sleeve 54. Therefore, by adjusting the length of the three support slides 55, the height of the bottom plate 56 can be adjusted, and the stability of the device can be ensured by inserting the ground nail 57 into the ground. When the entire device is firmly fixed, the survey instrument body 7 is placed on the upper end of the support plate 31, and then the adjusting screw 322 is rotated.

Through the cooperation of the three positioning plates 323, the survey instrument body 7 can be clamped and fixed to ensure its stability and safety during use. When the survey instrument body 7 is firmly installed, the protective top plate 332 is slidably sleeved on the three vertical rods 331 through the connecting hole 336 on the protective top plate 332, and then the protective top plate 332 is fixed by clamping the clamping ring 335 with the clamping groove 337. The main body 7 of the survey instrument is protected, which can not only prevent excessive light from affecting the use of the main body 7 of the survey instrument, but also block rain to ensure the normal use of the main body 7 of the survey instrument on rainy days, and then start the No. 1 forward and reverse motor 41, and the output end of the No. 1 forward and reverse motor 41 drives the driving bevel gear 42 to rotate. Since the driving bevel gear 42 and the transmission bevel gear 45 are meshed with each other, the transmission bevel gear 45 rotates accordingly, and the transmission bevel gear 45 is fixed to the lower end of the threaded sleeve 44, so the threaded sleeve 44 also starts to rotate, and the height adjustment screw 2 is threadedly connected with the threaded sleeve 44 through the height adjustment screw 2, so that the height adjustment screw 2 is moved upward in the support sleeve rod 1. The second forward and reverse motor 641 is moved downward, thereby adjusting the height of the survey instrument body 7 fixed inside the mounting mechanism 3 to meet the height requirements of different users. When marking is required, the second forward and reverse motor 641 is started, and the output end of the second forward and reverse motor 641 drives the baffle 642 to rotate through the rotating shaft, so that the through groove 643 on the baffle 642 is aligned with the discharge groove 65 at the lower end of the powder box 61. At this time, the powder flows out through the through groove 643 and the discharge groove 65 to complete the marking work. By controlling the rotation direction and angle of the second forward and reverse motor 641, the opening and closing of the mark can be flexibly adjusted to ensure the accuracy and clarity of the mark.
