Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and in particular to a soil organic matter testing device. Background Technology

[0002] Soil is a loose layer of material on the Earth's surface, composed of various particulate minerals, organic matter, water, air, microorganisms, etc., and can support plant growth. With the increasing number of soil-contaminated sites in China, it is necessary to test the concentration of volatile organic compounds (VOCs) in the soil to understand its VOC pollution status.

[0003] Volatile organic compounds (VOCs) refer to organic compounds with a saturated vapor pressure exceeding 70.91 Pa or a boiling point below 260°C at room temperature. They are the most common pollutants emitted by industries such as petroleum, chemical, pharmaceutical, printing, building materials, and spraying. VOCs in soil possess unique pollution characteristics compared to other pollutants, including concealment, heterogeneity, volatility, and toxicity. Their complex composition and high potential hazards necessitate their priority control in soil pollution remediation.

[0004] Patent application CN110031253B discloses a soil organic matter testing device, including a drill bit, a cylindrical part, and a rotating rod; the upper end of the drill bit is provided with a cylindrical part, and the upper end of the cylindrical part is threadedly connected to the rotating rod; the rotating rod is provided with a plug post, and the plug post is provided with an inlet pipe and an outlet pipe, and the rotating rod is provided with a feed port evenly distributed on the side; the outlet pipe is provided with a downward opening; and a water-spraying drying unit is provided inside the cylindrical part.

[0005] This device separates soil and water in swamps or paddy fields using the centrifugal force of a rotating truncated cone. This prevents excessive moisture in the sludge from affecting the heating and volatilization of volatile organic compounds and reduces the heating time of the sludge. However, due to the relatively complex internal structure of the device, disassembly and maintenance become difficult, which may lead to inconvenience in maintaining the internal components. To address these issues, we have developed a soil organic matter detection device. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The soil organic matter detection device disclosed in this utility model is mainly used in soil testing scenarios.

[0025] Reference Figures 1 to 4 A soil organic matter detection device includes: a drill bit body 1, a sleeve 2 fixedly connected to the top of the drill bit body 1, a top plate 3 provided on the top of the sleeve 2, a sealing plate 19 fixedly connected to the bottom of the top plate 3, the outer side of the sealing plate 19 being slidably connected to the inside of the sleeve 2, baffles 5 being equidistantly arranged inside the drill bit body 1, each baffle 5 having a movable groove 6 on one side, a connecting block 4 being slidably connected inside the movable groove 6, one side of the connecting block 4 being fixedly connected to one side of the inner wall of the drill bit body 1, and a driving component being provided at the bottom of the sealing plate 19 for driving the baffles 5 to rotate.

[0026] The drive assembly includes a protective shell 7, which is located at the bottom of the sealing plate 19. A motor 8 is installed inside the protective shell 7. A lead screw 9 is rotatably connected to the bottom of the protective shell 7. The bottom of the output shaft of the motor 8 is fixedly connected to the top of the lead screw 9. A movable block 10 is threadedly connected to the outside of the lead screw 9.

[0027] Two fixing blocks 12 are provided on the top of the baffle 5. Each fixing block 12 is fixedly connected to one side of an mounting block 13. The mounting block 13 is fixed to the baffle 5 by bolts.

[0028] The movable block 10 has equidistant connecting grooves 11 on its outer side. A first connecting rod 14 is provided inside the connecting groove 11. A second connecting rod 15 is provided between one side of the fixed block 12. A connecting rod 16 is rotatably connected between the first connecting rod 14 and the second connecting rod 15. A nut 17 is threadedly connected to the outer side of the lead screw 9.

[0029] The movable block 10 has equidistant connecting grooves 11 on its outer side. A first connecting rod 14 is provided inside the connecting groove 11. A second connecting rod 15 is provided between one side of the fixed block 12. A connecting rod 16 is rotatably connected between the first connecting rod 14 and the second connecting rod 15. A nut 17 is threadedly connected to the outer side of the screw 9. A flange 18 is fixedly connected to the outer side of the protective shell 7. The flange 18 is installed to the top plate 3 by bolts.

[0030] In the above technical solution, considering that the internal structure of the device is relatively complex, disassembly and maintenance become difficult, which may lead to inconvenience in maintaining internal components, the specific operation is as follows: Using the drive assembly, the motor 8 is started to drive the lead screw 9 to rotate, causing the movable block 10 to move downwards. Using the first connecting rod 14, connecting rod 16, second connecting rod 15, and fixed block 12, multiple sets of baffles 5 can be rotated, opening the baffles 5 downwards. One side of the baffle 5 will then fit against the inner wall of the drill bit body 1. The drill bit body 1 is then used to extract soil from swamps or paddy fields. After extraction, the motor is started again. The machine 8 drives the lead screw 9 to rotate in the opposite direction, causing the movable block 10 to move upward, rotating multiple sets of baffles 5 and closing them to prevent the mud from flowing out. Through the cooperation of the drive component and the baffles 5, the mud can be effectively prevented from flowing out, improving the efficiency of mud extraction. There are gaps between the baffles 5 to allow water to flow out. When maintaining the internal structure of the drill bit body 1, the bolts between the flange 18 and the top plate 3 can be removed, as can the bolts between the mounting block 13 and the baffles 5. Then, the nut 17 and the movable block 10 can be removed from the lead screw 9. This makes it easier to remove each component, making the disassembly and assembly of the overall structure simpler and shortening the maintenance time.

[0031] Reference Figures 1 to 4In a preferred embodiment, the baffle 5 is shaped like a quarter circle; setting the shape of the baffle 5 to a quarter circle allows the baffles 5 to fit together better, improves the overall sealing of the baffles 5, and better retains the mud in the sleeve 2.

[0032] Working principle: In use, the starting motor 8 drives the lead screw 9 to rotate, causing the movable block 10 to move downward. By utilizing the first connecting rod 14, connecting rod 16, second connecting rod 15, and fixed block 12, multiple sets of baffles 5 can be rotated, opening the baffles 5 downward. One side of the baffle 5 will fit against the inner wall of the drill bit body 1. Then, the drill bit body 1 is used to extract soil from swamps or paddy fields. After extraction, the motor 8 is started again to drive the lead screw 9 to rotate in the opposite direction, causing the movable block 10 to move upward, rotating the multiple sets of baffles 5 upward, closing the baffles 5. There are gaps between the baffles 5 to allow water to flow out. Then, the motor 8 is started again to open the baffles 5, and the internal mud is poured out for testing. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
