Description

Technical Field

[0001] The present invention relates to the technical field of soil collection and detection, and more specifically, to a portable soil collection, analysis and detection rod. Background Art

[0002] A soil collection, analysis and detection rod is a portable tool integrating soil sampling and preliminary analysis functions, designed specifically for the fields of agriculture, environmental monitoring and scientific research. Through an integrated design, this device optimizes the process from soil sample collection to rapid detection of key parameters. Its core functions include: multi-depth sampling, real-time physical and chemical index detection, data wireless transmission and intelligent analysis system. The technical highlights are the adoption of a highly wear-resistant stainless steel probe and an anti-corrosion coating to ensure durability in complex soil environments; at the same time, it is equipped with a laser positioning assistance system, which can accurately control the sampling depth error ≤ ±2 cm.

[0003] A soil collection, analysis and detection rod is a device integrating soil collection and preliminary analysis functions. It utilizes advanced sensing technology and data processing capabilities to achieve rapid and accurate collection and analysis of soil samples. In the prior art, such detection rods are usually equipped with various sensors, such as pH sensors, conductivity sensors, etc., which can detect the key physical and chemical indexes of the soil in real time while collecting soil samples. In addition, some high-end detection rods also have a wireless transmission function, which can transmit the collected data to a smart terminal or a cloud platform in real time, facilitating subsequent data processing and analysis by users.

[0004] Currently, during the sampling process of a soil collection, analysis and detection rod, if the depth control is inaccurate, it may lead to insufficient representativeness of the sample. Soils at different depths may have different physical and chemical properties, and inaccurate sampling will affect the accuracy of the analysis results. At the same time, during the collection and transportation process, soil samples are easily contaminated by the external environment, such as cross-contamination between other samples, residues on the tool surface, etc., affecting subsequent analysis results.

[0024] (6) In this solution, the pin screw is inserted into the pin screw hole and abuts against the upper end of the protective sleeve to prevent the upper half cylinder sleeve from rotating.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0033] Embodiment 1:

[0034] Please refer to Figures 1-5 , a portable soil collection, analysis and detection rod, including an operation table 1, a plurality of collection and detection cylinders 6, a protective sleeve 7 and a pair of fixing members 8. A driving motor 2 is fixedly connected to the lower end of the operation table 1, the output end of the driving motor 2 is fixedly connected to a drilling rod 3, a drill bit 4 is fixedly connected to the lower end of the drilling rod 3, an electric control rod 5 is fixedly connected to the middle inside of the drilling rod 3, a plurality of sliding grooves are opened on the outer side of the lower side of the drilling rod 3, and a plurality of collection and detection cylinders 6 are all installed in the sliding grooves, and the electric control rod 5 is located in the middle of the plurality of collection and detection cylinders 6. The protective sleeve 7 is installed at the lower end of the operation table 1 and sleeved outside the drilling rod 3 and the drill bit 4. A pair of plug screw holes are opened on the upper end of the operation table 1, and a pair of fixing members 8 are respectively threadedly connected to the plug screw holes. A pair of fixing grooves 9 are opened on the outer end of the operation table 1, and the fixing grooves 9 communicate with the plug screw holes. The electric control rod 5 is used to control the plurality of collection and detection cylinders 6 to collect and analyze soils at different depths, and while using the protective sleeve 7 to protect the drilling rod 3 and the drill bit 4, it also prevents the collected soil samples from being contaminated. Finally, the pair of fixing members 8 are used to unlock and lock the protective sleeve 7, so as to achieve the purpose of opening during collection and analysis and covering for protection when not in use.

[0035] The collection and detection cylinder 6 includes a sampling cylinder 61, the sampling cylinder 61 is slidably connected in the sliding groove, a detection sensor 62 is fixedly connected to the inner end of the sampling cylinder 61, and a magnetic plate 63 is embedded at one end of the sampling cylinder 61 close to the electric control rod 5. The electric control rod 5 is activated to magnetize and repel the magnetic plate 63, so that the sampling cylinder 61 is horizontally inserted into the soil for collection and sampling, and the detection sensor 62 is used to analyze and detect it.

[0036] The collection and detection tube 6 also includes a magnetic ring 64, which is slidably connected to the inner end of the sampling tube 61 and the outer end of the detection sensor 62. The magnetic ring 64 is fixedly connected to one end of the magnetic ring 64 close to the detection sensor 62 with a wiping ring 68, and the wiping ring 68 is in contact with the detection sensor 62. When the annular hemispherical airbag 65 repels and pushes the magnetic plate 63, the magnetic ring 64 is also repelled and pushed, so that the magnetic ring 64 drives the wiping ring 68 to slide along the outer end of the detection sensor 62 to clean its surface, thereby improving the detection accuracy of the detection sensor 62. Here, when the magnetic ring 64 is repelled by the magnetic force, the sampling tube 61 is inserted into the soil for sampling, and the repulsive force on the magnetic ring 64 is less than the squeezing force of the soil. Therefore, when the soil squeezes into the sampling tube 61, the magnetic ring 64 is pushed back into the sampling tube 61, and the magnetic ring 64 will not fall out of the sampling tube 61.

[0037] The collection and detection tube 6 also includes an annular hemispherical airbag 65, which is fixedly connected to the inner end of the sampling tube 61 and is located at the outer end of the detection sensor 62. A pair of rotating grooves are opened on the inner wall of the sampling tube 61, and a sealing plate 66 is rotatably connected in the rotating groove. A torsion spring is installed at the rotating connection of the sealing plate 66. A telescopic bag 67 is fixedly connected to the inner wall of the rotating groove, and the telescopic bag 67 is connected to the annular hemispherical airbag 65 through a pipeline. The telescopic bag 67 abuts against the sealing plate 66. When the magnetic plate 63 is attracted and retracted by the electric control rod 5, the magnetic ring 64 is also subjected to the magnetic force to squeeze the annular hemispherical airbag 65, so that the gas in the annular hemispherical airbag 65 enters the telescopic bag 67 to expand and bulge to push the sealing plate 66, thereby retaining the sample in the sampling tube 61 to prevent the soil sample from falling off.

[0038] The collection and detection tube 6 also includes a limit block 69, which is fixedly connected to the lower end of the sampling tube 61 near the magnetic plate 63. The inner wall of the sliding groove is provided with a limit groove matching the limit block 69. The limit block 69 slides in the limit groove, which can effectively prevent the sampling tube 61 from detaching.

[0039] The protective sleeve 7 includes a pair of upper sleeves 71, which are rotatably connected to the inner wall of the fixing groove 9. The outer end of the upper sleeve 71 is provided with a screw hole matching the fixing piece 8. The upper sleeve 71 is slidably connected with a lower sleeve 72 near one end of the drilling rod 3. The upper sleeve 71 is provided with a T-slot 73 near one end of the lower sleeve 72. A T-block 74 is slidably connected in the T-slot 73, and the T-block 74 is fixedly connected to the lower sleeve 72. The drilling rod 3 and the drill bit 4 are wrapped and protected by a pair of upper sleeves 71 and a pair of lower sleeves 72 to prevent them from falling and being damaged. The T-block 74 slides in the T-slot 73 to guide and limit the lower sleeve 72 to prevent it from falling off.

[0040] The protective sleeve 7 further includes a clamping groove 75 which is opened at one end of the lower half sleeve 72 close to the upper half sleeve 71. A movable clamping block 76 is slidably connected in the clamping groove 75. A pair of support grooves are opened on the inner wall of the clamping groove 75. An anti - detachment block 77 is slidably connected in the support groove, and the anti - detachment block 77 is fixedly connected to the movable clamping block 76. A support spring 78 is installed in the support groove. The anti - detachment block 77 is supported by the elastic force of the support spring 78, so that the movable clamping block 76 slides out of the clamping groove 75 and abuts against the lower end of the upper half sleeve 71, thereby enabling the lower half sleeve 72 to play a supporting role when it is lowered, and preventing the lower half sleeve 72 from being retracted when the detection rod falls.

[0041] The fixing member 8 includes a pin - clamping block 81 which is slidably connected in the pin - inserting screw hole. The lower end of the pin - clamping block 81 is fixedly connected with a pin - clamping screw 82, and the pin - clamping screw 82 is threadedly connected in the pin - inserting screw hole and is located in the fixing groove 9 and abuts against the protective sleeve 7. By inserting the pin - clamping screw 82 into the pin - inserting screw hole and abutting against the upper end of the protective sleeve 7, the rotation of the upper half sleeve 71 is prevented. After the upper half sleeve 71 rotates and the lower half sleeve 72 slides to the top, the pin - clamping screw 82 is screwed into the screw hole and presses the movable clamping block 76, so that the pin - clamping screw 82 is clamped into the clamping groove 75, thereby fixing the rotated upper half sleeve 71 and the lower half sleeve 72.

[0042] The fixing member 8 further includes an auxiliary half - ring 83 which is fixedly connected to the upper end of the pin - clamping block 81. A hook belt is provided between a pair of auxiliary half - rings 83. The auxiliary half - ring 83 can not only facilitate the screwing of the pin - clamping block 81, but also, in cooperation with the hook belt between a pair of auxiliary half - rings 83, facilitate the carrying of the detection rod.

[0043] A cleaning brush strip 10 is fixedly connected to one end of the lower half sleeve 72 close to the drill bit 4. When the lower half sleeve 72 slides up and down, the cleaning brush strip 10 is used to partially clean the soil impurities adhering to the outer end faces of the drilling rod 3 and the drill bit 4.

[0044] Working principle:

[0045] First, turn a pair of fixing members 8 to disengage them from abutting against the upper half barrel sleeve 71. Then, slide the lower half barrel sleeve 72 upward to the top. Next, rotate the upper half barrel sleeve 71 and place it in the fixing groove 9. Then, turn the fixing member 8 so that the latch screw 82 passes through the screw hole and presses against the movable latch 76 to snap it into the latching groove 75, thereby fixing the opened protective sleeve 7. Then, drive the drilling rod 3 and the drill bit 4 to rotate by the drive motor 2 to drill the soil to a certain depth. Subsequently, activate the electric control rod 5 to magnetize and repel the magnetic plate 63. At the same time, the magnetic ring 64 is also repelled. After the sampling cylinder 61 is inserted into the soil, push the magnetic ring 64 back into the sampling cylinder 61 and press the magnetic ring 64 against the annular hemispherical airbag 65, so that the gas in the annular hemispherical airbag 65 enters the telescopic airbag 67 to expand and bulge, pressing and rotating the sealing plate 66. Use a pair of sealing plates 66 to block the taken soil sample to prevent the soil from slipping. And the detection sensor 62 analyzes and detects until when the electric control rod 5 attracts and recovers the magnetic plate 63, at the same time, the magnetic ring 64 is magnetically attracted to press the annular hemispherical airbag 65 again, so that a pair of telescopic airbags 67 fully press the sealing plate 66, thereby using a pair of sealing plates 66 to separate and block the collected soil. Then, take out the drilling rod 3 from the soil. When sampling, also activate and magnetize the electric control rod 5 to repel the collection and detection cylinder 6, so that the sampling cylinder 61 slides out and the magnetic ring 64 pushes the soil in the sampling cylinder 61 out.

[0046] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0047] The present invention controls multiple collection and detection cylinders 6 through an electric control rod 5 to collect and analyze soils at different depths, enabling more accurate acquisition of soil samples at different depths, improving the representativeness of the samples, ensuring the accuracy of the analysis results, and solving the problem of insufficient representativeness of samples caused by inaccurate depth control of the existing soil collection, analysis, and detection rod; the protective sleeve 7 is opened during collection and analysis and covered for protection when not in use, which can effectively prevent the collected soil samples from being polluted by the external environment. When the lower half sleeve 72 slides up and down, the cleaning brush strip 10 can partially clean the soil impurities adhering to the outer end faces of the drilling rod 3 and the drill bit 4, reducing the pollution of impurities to subsequent sampling and samples; when the annular hemispherical airbag 65 is affected by magnetic force, it repels and pushes the magnetic ring 64, causing the magnetic ring 64 to drive the wiping ring 68 to slide along the outer end of the detection sensor 62 to clean its surface, thereby improving the accuracy of detection by the detection sensor 62; inside the collection and detection cylinder 6, when the electric control rod 5 is magnetized to attract and retract the magnetic plate 63, the magnetic ring 64 is affected by magnetic force to squeeze the annular hemispherical airbag 65, causing the gas in the annular hemispherical airbag 65 to enter the telescopic bladder 67 and expand to push the sealing plate 66, thereby retaining the sample in the sampling cylinder 61 and preventing the soil sample from falling off; the protective sleeve 7 wraps and protects the drilling rod 3 and the drill bit 4 through a pair of upper half sleeves 71 and a pair of lower half sleeves 72 to prevent them from falling and being damaged; the T-shaped block 74 slides in the T-shaped groove 73 to guide and limit the lower half sleeve 72 to prevent it from falling off; a movable latch block 76 is slidably connected in the latching groove 75, and the elastic force of the support spring 78 causes the movable latch block 76 to slide out of the latching groove 75 and abut against the lower end of the upper half sleeve 71, enabling the lower half sleeve 72 to play a supporting role when lowered to prevent the lower half sleeve 72 from being retracted when the detection rod falls; the upper half sleeve 71 is prevented from rotating by inserting the pin screw 82 into the pin screw hole and abutting against the upper end of the protective sleeve 7; after the upper half sleeve 71 rotates and the lower half sleeve 72 is slid to the top, the pin screw 82 is screwed into the screw hole and squeezes the movable latch block 76, causing the pin screw 82 to be stuck in the latching groove 75 to fix the rotated upper half sleeve 71 and the lower half sleeve 72. The auxiliary half ring 83 not only facilitates the screwing of the latch block 81, but also cooperates with the hook belt, facilitating the carrying of the detection rod.
