Description

Technical Field

[0001] The present invention relates to the technical field of soil detection, and in particular to a forest soil composition detection device and a method for using the same. Background Art

[0002] As global climate change intensifies, the stability of forest soil carbon pools is impacted, leading to an increased demand for forest soil composition testing. Traditional testing methods typically involve laboratory soil processing and analysis, which is time-consuming. However, forest environmental samples are susceptible to interference from biological activity and temperature and humidity fluctuations, necessitating rapid on-site testing.

[0003] On-site rapid testing devices often use an integrated drill bit or a fixed sampling tube, which can easily lead to mixing of materials at different sampling points, causing cross-contamination, resulting in a high sample rejection rate, affecting the accuracy of test results, and increasing the cost of repeated sampling.

[0004] Patent CN118794733B discloses a garden soil sampling and drying component detection device and its use method. The above patent realizes the automation of sampling, drying and detection, which is convenient and fast. The soil at a specified depth is sampled through the sampling device without the need for human intervention.

[0057] The detection seat 1 is movably mounted on the outer wall of the connecting seat 2, the detection seat 1 is fixedly mounted on the outer wall of the soil-taking barrel 3, the detection seat 1 is movably mounted on the outer wall of the connecting unit 11, the top of the outer wall of the connecting unit 11 is fixedly connected with a lifting plate 10, the lifting plate 10 is connected to the outer wall of the rotating screw 8 by a thread, the rotating screw 8 is movably mounted on the outer wall of the driving motor 7, the bottom of the outer wall of the lifting plate 10 is fixedly connected to the first motor 5, the first motor 5 is connected to the transmission block 15 through a rotating shaft, a transmission seat 14 is provided on the top of the outer wall of the connecting seat 2, the bottom of the outer wall of the transmission seat 14 is fixedly connected to the soil-taking auger 4, and the transmission seat 14 is movably mounted on the outer wall of the transmission block 15.

[0058] Furthermore, after the sampling of the soil barrel 3 is completed, the lifting plate 10, the connecting unit 11, the connecting seat 2, and the soil barrel 3 are driven upward by the driving motor 7. The limit assembly contacts the connecting seat 2 to prevent the connecting seat 2 from continuing to move, so that the connecting seat 2 and the soil barrel 3 move to the required position. The motor in the detection frame 22 drives the rotating plate 48 to rotate, and the rotating plate 48 drives the soil box 21 to perform a circular motion. The soil box 21 gradually approaches the positioning groove 20. Since the size of the positioning groove 20 is larger than the size of the outer soil box 21, the soil box 21 is gradually inserted into the positioning groove 20. The size of the second unearthing groove 19 is smaller than the size of the inner soil box 21. Therefore, when the first motor 5 drives the transmission block 15, the transmission seat 14, and the soil auger 4, the soil auger 4 drives the soil in the soil barrel 3 to move upward, so that the soil gradually passes through the first unearthing groove 18 and the second unearthing groove 19, and the soil can move into the soil box 21.

[0059] The anti-slip block 47 on the rotating plate 48 resists the soil box 21, preventing the soil box 21 from sliding on the rotating plate 48. The rubber clamping block 49 is in the clamping groove 50, so that the rubber clamping block 49 clamps the soil box 21 to prevent the soil box 21 from deflecting on the rotating plate 48. The rubber clamping block 49 and the anti-slip block 47 prevent the soil box 21 from rotating with the rotating plate 48 as the angle between the rotating plate 48 and the horizontal plane increases, causing the soil box 21 to have the risk of moving on the rotating plate 48; the limit assembly resists the top of the connecting seat 2, thereby ensuring that the positioning groove 20 is in the specified position, ensuring that the soil box 21 can be inserted into the positioning groove 20 when the rotating plate 48 drives the soil box 21; the soil is sent into the soil box 21 through direct contact with the connecting seat 2, avoiding the soil being transferred to the soil box 21 by the transmission mechanism, and cross contamination caused by soil remaining on the transmission mechanism.

[0061] When the positioning block 31 is moved to a position aligned with the positioning slot 30, under the action of the first spring 32, the first spring 32 drives the positioning block 31 to be inserted into the positioning slot 30 on the transmission seat 14. At this time, the transmission block 15 drives the positioning block 31 to perform a circular motion, and the positioning block 31 drives the transmission seat 14 to rotate.

[0063] A first unearthing groove 18 is provided on the side wall of the soil-taking cylinder 3, and a second unearthing groove 19 is provided in the connecting seat 2. The first unearthing groove 18 is communicated with the second unearthing groove 19. A positioning groove 20 is provided on the side wall of the connecting seat 2, and the positioning groove 20 is communicated with the second unearthing groove 19. The side wall of the resistance block 24 is fixedly connected to the detection frame 22, and the bottom of the inner wall of the detection frame 22 is rotatably connected to the rotating plate 48. A soil-taking box 21 is placed on the rotating plate 48. The outer wall of the soil-taking box 21 is symmetrically provided with a card slot 50, and the outer wall of the rotating plate 48 is symmetrically provided with a rubber card block 49. The rubber card block 49 is movably fitted on the outer wall of the card slot 50, and the side wall of the rotating plate 48 is fixedly connected to the anti-sliding block 47.

[0064] Furthermore, the driving motor 7 between the side plates 16 is used to control the connecting seat 2 and the soil sampling tube 3 to perform soil sampling. After the soil sampling is completed, the connecting seat 2 and the soil sampling tube 3 are moved to the designated position by the driving motor 7 on the horizontal plate 9. The rotating plate 48 and the soil sampling box 21 are driven by the motor to insert the soil sampling box 21 into the positioning groove 20. The soil passes through the first discharging groove 18 and the second discharging groove 19 and enters the soil sampling box 21. The rotating plate 48 and the soil sampling box 21 are reset by the motor. The fourth motor 45 is started. The fourth motor 45 drives the rotating baffle 46 to rotate through the rotating shaft. The rotating baffle 46 gradually contacts the soil sampling box 21. The rotating baffle 46 drives the soil sampling box 21 to move, and the soil sampling box 21 is moved to the conveyor belt on the detection frame 22. The soil sampling box 21 is sent to the detector 54 through the conveyor belt for soil composition detection.

[0065] During the soil testing of other sampling points, the connecting seat 2 and the soil taking tube 3 in the testing seat 1 are taken out, and the unused connecting seat 2 and soil taking tube 3 are taken out from the storage box 23. The positioning groove 20 of the connecting seat 2 is directed toward the testing seat 1, and the connecting seat 2 is pushed into the testing seat 1. In addition, by controlling the motor on the rotating seat 27, the position of the telescopic device 26 on the rotating seat 27 is adjusted, so that the telescopic device 26 is gradually moved to the top of the storage rack 25. By controlling the telescopic device 26, the suction cup at the bottom of the telescopic device 26 adsorbs the soil taking box 21 in the storage rack 25. The motor on the rotating seat 27 is continued to be controlled to rotate the telescopic device 26 to the initial position. The soil taking box 21 is driven to move downward, so that the soil taking box 21 gradually approaches the rotating plate 48, and the soil taking box 21 contacts the rubber clamping block 49, the rubber clamping block 49 is deformed, and the rubber clamping block 49 is gradually inserted into the clamping slot 50. At this time, when the telescopic device 26 contracts, the soil taking box 21 is clamped by the rubber clamping block 49, so that the soil taking box 21 does not move upward with the telescopic device 26, thereby placing the unused soil taking box 21 on the rotating plate 48, so that each sampling test is an independent and pure sample, avoiding the influence of the previous residual soil on the subsequent sampling, and improving the accuracy of the soil composition test results; the connecting seat 2 and the soil taking cylinder 3 are stored in the storage box 23, thereby improving the portability of the equipment.

[0066] Working principle: Move the positioning slot 20 toward the sliding slot 51, push the connecting seat 2 into the detection seat 1, and the driving motor 7 drives the rotating screw 8, the lifting plate 10, the connecting unit 11, and the first motor 5. The first motor 5 drives the transmission block 15 to insert into the transmission seat 14, and the connecting unit 11 is inserted into the connecting seat 2. The second motor 6 drives the cam 33, and the longer end of the cam 33 moves into the fixed slot 35.

[0067] The servo motor 28 drives the first gear 42 and the first bearing plate 29. The first gear 42 drives the second gear 43 and the second bearing plate 44. The first bearing plate 29 and the second bearing plate 44 no longer support the connecting base 2. Soil sampling is performed by driving the motor 7 and the first motor 5.

[0068] By driving the motor 7, the connecting seat 2 and the soil taking tube 3 are reset, the limiting ring 12 contacts the connecting seat 2, the rotating plate 48 drives the soil taking box 21 to be inserted into the positioning groove 20, and the soil enters the soil taking box 21, so that the rotating plate 48 and the soil taking box 21 are reset. The fourth motor 45 drives the rotating baffle 46 and the soil taking box 21, and the soil is detected by the detector 54.
