Description

Technical Field

[0002] With the growth of global population and the increase of agricultural demand, soil resources are facing increasing pressure. Organic matter content, as one of the important indicators of soil health, directly affects soil fertility, structure and water retention capacity. In addition, organic matter is an important source of nutrients and structural regulator in soil. It can improve the physical, chemical and biological properties of soil and plays a vital role in soil fertility, water retention and air permeability. However, human activities such as over-cultivation, over-fertilization and over-grazing have aggravated the loss of soil organic matter, leading to soil degradation and affecting agricultural productivity. Therefore, how to accurately and real-time monitor the content of soil organic matter has become the key to soil improvement and sustainable agricultural development.

[0003] In the existing soil testing, it is often necessary to manually sample the soil and then use the testing equipment to test the soil samples. When manually sampling, operators may have differences in sampling location, depth, quantity, etc., resulting in poor representativeness of soil samples and failure to accurately reflect the actual situation of the soil in the entire region. In addition, different operators may have different understandings of sampling methods, soil layers, etc., which are prone to deviations and affect the accuracy and reliability of soil testing results. Moreover, manual sampling requires personnel to collect soil samples point by point in a large area, which is labor-intensive and time-consuming, especially in large-scale agriculture or geological exploration, and the efficiency is significantly reduced. At the same time, it is limited to specific areas or easily accessible surface soils, and it is difficult to ensure that soil samples of different terrains and different depths can be fully collected, and the spatial heterogeneity and vertical distribution characteristics of the soil are easily ignored.

The second motor and the second hydraulic valve are in operation, causing the rotating plate to flip 180 degrees and move downward at the same time, and then the second motor and the second hydraulic valve are in operation, and the second motor drives the synchronous belt assembly to transmit, so that when the second threaded rod moves downward, the second threaded rod bottom assembly follows the synchronous movement and rotates. At this time, the telescopic end of the second hydraulic valve is close to the connecting plate, and the three clamping plates are in a closed state, and the ground is broken and drilled into. When the clamping plate enters a certain depth of the ground, the telescopic end of the second hydraulic valve performs a telescopic process, causing the slide plate to move back and forth in the linear direction of the limit rod. Under the action of the third connecting plate, the three clamping plates perform an opening and closing process, thereby sampling the soil sample. When the sampling is completed, the above operation steps are repeated in reverse, so that the sampled soil sample is moved to the bottom of the spectrometer for detection, ensuring that the sample and the spectrometer always maintain a fixed relative position, and can provide consistent lighting conditions and angles during the detection process, thereby improving the accuracy of the spectral signal and avoiding signal attenuation or distortion caused by angle deviation.

[0025] like Figure 7-Figure 9As shown, two slide bars 18 are fixedly connected inside the frame 17, and the two slide bars 18 penetrate and slide with a moving block 19, one side of the moving block 19 is rotatably connected with a gear 27, and the gear 27 is fixedly connected with an L-shaped plate 28 on the side away from the moving block 19, and the other side of the moving block 19 is rotatably connected with a rotating plate 20, and the top surface of the rotating plate 20 is rotatably connected with a synchronous belt assembly 21, and one of the synchronous wheels in the synchronous belt assembly 21 is threadedly connected with a second threaded rod 36, and the second threaded rod 36 is fixedly connected with a fixed frame 29 at the penetration end, and a second hydraulic press 30 is installed inside the fixed frame 29, and the telescopic end of the second hydraulic press 30 is slidably connected with the fixed frame 29, and the penetration end of the second hydraulic press 30 is fixedly connected with a slide plate 32, and the slide plate 32 is arranged in a triangular structure, and the slide plate 32 is slidably connected with a plurality of limit rods 31, so as to realize automated soil sampling, movement and detection. No human intervention is required, which not only improves the sampling speed, but also reduces the errors of human operation. At the same time, it reduces the dependence on operators, saves human resources and time costs. One of the through ends of the limit rod 31 is fixedly connected to the fixed frame 29, and the other through end of the limit rod 31 is fixedly connected to the connecting plate 33. The three ends of the slide plate 32 are rotatably connected to the third connecting plate 34, and the other end of the third connecting plate 34 is rotatably connected to the clamping plate 35.

The connecting shaft of the rotating plate 20 is rotatably connected to the moving block 19, and the through end of the rotating plate 20 is fixedly connected to the gear 27.

[0026] The working principle of this embodiment is as follows: the staff can push the handle 3 and move the entire device to the inspection location under the action of the universal wheel 6. During the movement, the spring column 5 at the bottom of the base plate 1 can be deformed and contracted to reduce the impact of the vibration generated during the movement on the components inside the base plate 1.

[0027] Then, several first motors 9 can be operated simultaneously or intermittently to rotate the first threaded rod 10, so that the slider 8 moves along the linear direction of the first fixed plate 7. When the slider 8 moves, the first connecting plate 11 rotates relative to the slider 8. At the same time, the two ends of the second connecting plate 12 generate transmission for the first connecting plate 11 and the fixed rod 14, so that the triangular plate 13 can move in multiple directions such as up, down, left, right, front and back in the space of the mask 2. Extensive sampling can be carried out in an area, ensuring that data is obtained from different positions, different depths and different soil layers, which is helpful to obtain comprehensive representative data of the soil in the area, rather than relying solely on sampling at a single position, thereby avoiding sample bias.

[0028] When the triangle plate 13 is close to the ground, the first hydraulic machine 15 operates to push the moving block 19 to move along the linear direction of the slide bar 18, and the gear 27 follows the synchronous movement. When the gear 27 contacts the tooth plate 26, meshing transmission is generated. At the same time, the L-shaped plate 28 follows the rotation synchronously, so that the end of the L-shaped plate 28 away from the frame 17 rotates from the top of the gear 27 to the bottom of the gear 27 and slides along the slide groove 25. In addition, the rotating plate 20 follows the gear 27 to rotate synchronously, causing the rotating plate 20 to flip 180 degrees and move downward at the same time.

[0029] Then the second motor 22 and the second hydraulic press 30 are operated, and the second motor 22 drives the synchronous belt assembly 21 to transmit, so that when the second threaded rod 36 moves downward, the bottom assembly of the second threaded rod 36 follows the synchronous movement and rotation. At this time, the telescopic end of the second hydraulic press 30 is close to the connecting plate 33, and the three clamping plates 35 are in a closed state, and the ground is broken and drilled. When the clamping plate 35 enters a certain depth of the ground, the telescopic end of the second hydraulic press 30 performs a telescopic process, prompting the slide plate 32 to move back and forth in the linear direction of the limit rod 31. Under the action of the third connecting plate 34, the three clamping plates 35 perform an opening and closing process, thereby sampling soil samples.

[0030] When the sampling is completed, the above steps are repeated in reverse, so that the sampled soil sample is moved to the bottom of the spectrum detector 16 for detection, and then after sampling a fixed point, the above steps are repeated to implement multi-point sampling detection on the middle of the bottom plate 1.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
