A lighting lamp 2 is fixedly installed on the top surface of the housing 1. The lighting lamp 2 is fixed to the housing 1 by bolts or rivets to ensure its firm installation and facilitate later maintenance and replacement. The material of the housing 1 can be corrosion-resistant metal or high-strength plastic to ensure durability and stability in the outdoor environment. The lighting lamp 2 is used to provide a uniform light source during the measurement to ensure the accuracy of spectral data collection. A fiber optic cable 3 is connected to the side of the housing 1. The fiber optic cable 3 is connected to an external spectrometer. The interface of the fiber optic cable 3 can be installed by snap connection or threaded connection to ensure the stability and tightness of its connection and avoid interference from external environmental light. The material of the fiber optic cable 3 can be selected as a low-loss fiber optic cable 3 to ensure the transmission quality of the optical signal. Vertical grooves 4 are formed on the surface of the housing 1. The material of the vertical grooves 4 is the same as that of the housing 1 and is made by integral casting or precision cutting to ensure the smooth sliding of the slider 5 in the vertical grooves 4. The inner wall of the vertical grooves 4 is slidably connected with a slider 5. The material of the slider 5 is high-strength plastic or aluminum alloy, which has good wear resistance and corrosion resistance and can maintain the flexibility of sliding during long-term use. One end of the slider 5 is fixedly installed with a disc 6. The disc 6 is fixed to the slider 5 by screws or rivets to ensure that it does not loosen during its movement.

Embodiment

[0027] Please refer to Figures 4-6 , a carrying mechanism is provided at the top of the housing 1. The carrying mechanism includes a handle 11, and the handle 11 is fixedly installed at the top of the housing 1. The handle 11 is fixed to the housing 1 by bolts or welding to ensure its firmness when lifting the device. The material of the handle 11 can be selected from aluminum alloy or engineering plastics to ensure its strength and durability when lifting. A circular groove 12 is formed on the inner side of the handle 11, and a magnet 13 is fixedly installed on the inner wall of the circular groove 12. The magnet 13 is fixed to the inner wall of the circular groove 12 by adhesive or embedded installation to ensure its firmness and suction effect during use. The material of the magnet 13 is a strong magnetic material, such as neodymium iron boron, to ensure its stable suction force on the cylinder 14. A cylinder 14 is installed on the inner wall of the circular groove 12, and the cylinder 14 is adapted to the size of the circular groove 12 to ensure its tight fit when inserted and avoid loosening. The material of the cylinder 14 is ferritic stainless steel, which has good corrosion resistance and magnetic suction performance, to ensure that the cylinder 14 can be firmly fixed in the circular groove 12 under the suction force of the magnet 13. A sweat-absorbing block 15 is fixedly installed at the bottom end of the cylinder 14. The sweat-absorbing block 15 is of a rectangular structure and is fixed to the bottom end of the cylinder 14 by snap or bonding to ensure its stability during use and facilitate disassembly and cleaning. The material of the sweat-absorbing block 15 is pure cotton, which can effectively absorb the sweat secreted by the hand and avoid the situation of slipping off due to hand sweat, especially suitable for use in outdoor high temperature or long-term operation. When the sweat-absorbing block 15 needs to be cleaned, the staff only needs to simply pull it to remove the cylinder 14 and the sweat-absorbing block 15. The disassembly process is quick and convenient, and it can be reinstalled after cleaning to ensure the cleanliness and normal use of the device.

[0028] Working principle: The optical fiber 3 is connected to an external spectrometer. When measuring the soil, only need to place the housing 1 on the ground, then illuminate the soil through the lighting lamp 2, and then collect the spectral data of the soil through the optical fiber 3 and the spectrometer. At the same time, if the ground is uneven, the staff can step on the pedal 9 downward. At this time, the pedal 9 can drive the slider 5 to slide in the vertical groove 4. When the slider 5 moves downward, it can drive the disc 6 to move downward. Subsequently, the disc 6 drives the cutter 7 to move downward until the cutter 7 enters the soil. At this time, the cutter 7 can cut into the soil and seal the periphery of the housing 1. In this way, during the measurement, it can avoid light leakage caused by the uneven ground, thereby causing spectral data errors. And through the set tension spring 8, due to the pulling force of the tension spring 8, the tension spring 8 can pull the slider 5 to slide upward in the vertical groove 4. Subsequently, the slider 5 can drive the disc 6 and the cutter 7 to reset upward. At this time, the cutter 7 is lifted. Through the cooperation of the cutter 7 and the housing 1 designed by the utility model, it can effectively seal the periphery of the housing 1, avoid the light leakage problem caused by the uneven ground, thereby improving the measurement accuracy of the spectral data, avoiding environmental light interference, ensuring that external light does not enter the measurement area through the cutter 7, making the collected spectral data more accurate, reducing the error caused by the uneven terrain, and the staff can control the pedal 9 through a simple stepping action to drive the movement of the slider 5, the disc 6 and the cutter 7. The whole operation process is simple and efficient, adapting to different measurement scenarios. The design of the tension spring 8 enables the cutter 7, the disc 6 and the slider 5 to automatically reset after the measurement is completed, without manual intervention, improving the use convenience and working efficiency of the device. By setting the handle 11, it is convenient to lift the housing 1. And when the staff carries the utility model through the handle 11, the sweat-absorbing block 15 made of pure cotton can absorb the sweat secreted by the hand. In this way, when used outdoors, it can reduce the probability of slipping off due to sweat, facilitating actual carrying. At the same time, when it is necessary to clean the sweat-absorbing block 15, the staff only needs to pull the sweat-absorbing block 15 downward. Subsequently, the sweat-absorbing block 15 can drive the cylinder 14 to leave the circular groove 12. At this time, the sweat-absorbing block 15 can be removed, and then the sweat-absorbing block 15 can be cleaned. When installing the sweat-absorbing block 15, only need to align the cylinder 14 on the sweat-absorbing block 15 and insert it into the circular groove 12. After the cylinder 14 abuts against the inner wall of the circular groove 12, at this time, the magnet 13 can attract the cylinder 14 made of ferritic stainless steel, and then the sweat-absorbing block 15 can be limited. Through the handle 11 set by the utility model, the device is easier to lift and carry, especially in outdoor operations, improving the use convenience. At the same time, the sweat-absorbing block 15 is made of pure cotton, which can effectively absorb the sweat of the hand, reducing the risk of slipping off caused by sweat, especially suitable for outdoor high temperature or long-term operations. The design of the sweat-absorbing block 15 also supports quick disassembly. The staff only needs to perform a simple operation to remove the sweat-absorbing block 15 for cleaning, maintaining hygiene and the good state of the device. And through the insertion of the cylinder 14 into the circular groove 12 and the attraction of the magnet 13 and the ferritic stainless steel material, it is ensured that the sweat-absorbing block 15 is installed firmly and is not easy to loosen.
