Description

Technical Field

[0001] This invention relates to the field of soil sampling equipment technology, and more specifically, to a static experimental chamber for automatically collecting and sealing samples. Background Technology

[0002] In field experiments, it is often necessary to analyze the effects of different treatments, such as fertilization, irrigation, and straw return, on methane oxidation in soil. It is also essential to assess the impact of pollutants (such as heavy metals and pesticides) on soil physicochemical properties and soil microbial communities. During actual experiments, soil samples need to be collected and preserved regularly for laboratory testing. For some experiments involving soil microorganisms, samples also need to be stored at low temperatures and brought back to the laboratory for analysis. Certain experiments, such as monitoring changes in surface methane and carbon dioxide concentrations, also require periodic gas sample collection.

[0003] Currently, static chambers are commonly used in field experiments to conduct the aforementioned experiments, typically involving periodic sampling at the test site. However, during the experiments, some field sampling points are far from the laboratory, making travel inconvenient and costly. Furthermore, the static chamber must be opened for each sampling process, severely impacting the accuracy of subsequent soil and gas sample collection, ultimately affecting the experimental results. Additionally, static chamber experiments generally require simultaneous soil and gas sampling, which is difficult to achieve in practice. Moreover, even without human interference, most static chambers struggle to maintain a good seal, affecting the experimental results. Summary of the Invention

[0004] To overcome the problem of low efficiency in soil and gas sampling in field experiments in the prior art, the present invention provides a static experimental chamber for automatically collecting and sealing samples.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a static experimental box for automatically collecting and sealing samples, comprising: a box body, wherein the bottom of the box body has an opening for sealing and fixing to the soil, the inside of the box body is provided with a soil sampling mechanism and a soil sealing mechanism, the soil sealing mechanism has multiple sealing containers for sealing soil samples, the soil sampling mechanism is used to grab soil samples and place them into the sealing containers of the soil sealing mechanism, and the box body is also connected to a gas sampling mechanism, which is used to sample and preserve the gas inside the box body.

[0006] In the technical solution of this invention, the box is fixed above the soil to form a good static sealing effect. Soil samples are collected into the soil sealing mechanism through the soil sampling mechanism. Multiple sealing containers set on the soil sealing mechanism can seal multiple soil samples. The gas inside the box is sampled and preserved through the gas sampling mechanism. This enables the regular collection of soil samples and gas samples inside the box. Compared with manual sampling, this can effectively improve efficiency, reduce manpower, time and economic costs, and effectively avoid the impact of human sampling interference on the accuracy of sample experiments.

[0007] Furthermore, the soil sampling mechanism includes a moving drive component and a sampling claw component. The fixed end of the moving drive component is fixedly connected to the housing, and the output end of the moving drive component is connected to the sampling claw component to drive the sampling claw component to move inside the housing. The lower end of the sampling claw component can grasp soil samples.

[0008] In this solution, the sampling claw assembly is driven by a moving drive component to move within the box, so as to grab soil samples multiple times or grab soil samples from different locations and transport them to different storage containers of the soil storage mechanism, thereby reducing the time and labor costs required for regular manual sampling.

[0009] Furthermore, the sampling claw assembly includes a sampling container, a sampling claw piece, and an opening and closing drive mechanism. The bottom of the sampling container has an opening, and the sampling claw piece is hinged around the opening of the sampling container. The fixed end of the opening and closing drive mechanism is fixedly connected to the sampling container, and the output end of the opening and closing drive mechanism is connected to the sampling claw piece to drive the sampling claw piece to open and close.

[0010] In this solution, the sampling claw is driven to rotate by the opening and closing drive mechanism, thereby opening or closing the bottom opening of the sampling container. When the sampling claw is open, the sampling claw assembly moves downward and inserts the lower part of the sampling claw into the soil. Then, the sampling claw is driven to close by the opening and closing drive mechanism, thereby grabbing the soil into the sampling container for subsequent transportation.

[0011] Furthermore, the opening and closing drive mechanism includes an opening and closing drive track seat, an opening and closing drive slide plate, and an opening and closing drive motor. The opening and closing drive track seat is fixedly connected to the sampling container, the opening and closing drive slide plate is slidably connected to the opening and closing drive track seat, the fixed end of the opening and closing drive motor is fixedly connected to the opening and closing drive track seat, the output end of the opening and closing drive motor is drively connected to the opening and closing drive slide plate to drive the opening and closing drive slide plate to move along the opening and closing drive track seat, and the end of the opening and closing drive slide plate facing the sampling claw is movably connected to the sampling claw.

[0012] In this solution, the opening and closing drive motor drives the opening and closing drive slide plate to move along the opening and closing drive track seat. Since one end of the opening and closing drive slide plate is movably connected to the sampling claw, the opening and closing drive motor can indirectly drive the sampling claw to perform opening and closing movements, thereby controlling the sampling claw assembly to grab or put down the soil sample.

[0013] Furthermore, one end of the opening and closing drive slide plate is rotatably connected to an opening and closing bearing, the sampling claw is magnetic, and the opening and closing bearing is magnetically attracted to the sampling claw and can roll on the sampling claw.

[0014] Furthermore, the motion drive assembly includes a translation motor, a translation transmission module, a lifting motor, and a lifting transmission module. The output end of the translation motor is connected to the input end of the translation transmission module to drive the output end of the translation transmission module to translate. The output end of the translation transmission module is connected to the lifting transmission module. The output end of the lifting motor is connected to the input end of the lifting transmission module to drive the output end of the lifting transmission module to lift. The sampling claw assembly is connected to the output end of the lifting transmission module.

[0015] In this solution, a translational motor drives a translational transmission module, a lifting motor drives a lifting transmission module, the translational transmission module moves the lifting transmission module, and the lifting transmission module moves the sampling claw assembly up and down, thereby realizing the horizontal and vertical movement of the sampling claw assembly to facilitate the collection and transportation of soil samples.

[0016] In this solution, the bearing and the sampling claw are connected by magnetic adsorption, and the bearing can roll on the sampling claw, thereby realizing the movable connection between the opening and closing drive slide and the sampling claw.

[0017] Furthermore, the sealing container includes a sealing cylinder, a cover plate, and an elastic tightening member. The upper end of the sealing cylinder has an opening, and multiple cover plates are slidably connected to the opening of the sealing cylinder from the center outwards. The elastic tightening member is connected to each cover plate to close the opening of the sealing cylinder. The opening and closing drive slide plate can move outwards to drive the sampling claw to open, allowing the soil sample in the sampling container to fall out. At the same time, the other end of the opening and closing drive slide plate can push the cover plate to open, allowing the soil sample to fall into the sealing cylinder.

[0018] In this solution, the cover plate seals the opening of the cylinder under the action of the elastic tightening component, which can achieve effective sealing of the storage container. When the sampling claw assembly grabs the soil sample and moves it above the storage container, one end of the opening and closing drive slide plate pulls the sampling claw to open, and at the same time, the other end of the opening and closing drive slide plate pushes the cover plate to open, transferring the soil sample into the storage cylinder.

[0019] Furthermore, the upper end of the sealing cylinder is provided with a sealing groove, the lower end of the cover plate is provided with a sealing slide rail, the sealing slide rail is slidably connected in the sealing groove, and the upper end of the cover plate is provided with a force-bearing column, which is used to abut against one end of the opening and closing drive slide plate.

[0020] In this design, the cover plate is guided to slide by a sealing groove and a sealing rail, and a force-bearing column is provided to facilitate the opening and closing of the sliding plate.

[0021] Furthermore, the gas sampling mechanism includes a gas delivery pipe, multiple gas delivery valves, and multiple gas collection bottles. The inlet end of the gas delivery pipe is connected to the housing, and the gas delivery pipe has multiple outlet ends that are respectively connected to each of the gas collection bottles. Each of the gas delivery valves is respectively located at each of the outlet ends of the gas delivery pipe.

[0022] In this solution, the gas collecting bottle is initially in a vacuum state. Since the gas inside the box has a certain pressure, under the influence of the pressure difference, opening the gas supply valve allows the gas in the box to flow into the gas collecting bottle for storage through the gas supply pipe. By setting multiple gas supply valves and multiple gas collecting bottles, the gas inside the box can be collected and stored multiple times, reducing labor costs.

[0023] Furthermore, the opening of the box body faces the soil and has internal teeth, and a partition ring plate is fixedly connected to the lower outer side of the box body. A rotating closing ring is threadedly connected to the outer side of the partition ring plate, and the lower end of the rotating closing ring faces the soil and has external teeth. A space capable of accommodating soil is formed between the box body, the partition ring plate and the rotating closing ring.

[0024] In this solution, the inner teeth are first inserted into the soil by rotating the box, and then the rotating sealing ring is moved downward by rotating the rotating sealing ring, so that the outer teeth are inserted into the soil. This allows a certain amount of soil to be contained in the space between the outer and inner teeth. At the same time, the inner and outer teeth engage with the soil, improving the sealing effect of the box and preventing external interference inside the box.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] I. The static experimental chamber for automatically collecting and sealing samples of the present invention fixes the chamber above the soil to form a good static sealing effect. Soil samples are collected into the soil sealing mechanism through a soil sampling mechanism. Multiple sealing containers on the soil sealing mechanism can seal multiple soil samples. Gas sampling mechanism samples and preserves the gas inside the chamber. It can realize the periodic collection of soil samples and gas samples inside the chamber. Compared with manual sampling, it can effectively improve efficiency, reduce manpower, time and economic costs, and effectively avoid the impact of human sampling interference on the accuracy of sample experiments.

[0027] II. The static experimental chamber for automatically collecting and sealing samples of the present invention has a cover plate that seals the opening of the cylinder under the action of an elastic tightening member, which can effectively seal the storage container. When the sampling claw assembly grabs the soil sample and moves it above the storage container, one end of the opening and closing drive slide plate pulls the sampling claw to open, and at the same time, the other end of the opening and closing drive slide plate pushes the cover plate to open, transferring the soil sample into the storage cylinder, thereby realizing the automatic release and sealing of the soil sample.

In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The technical solution of the present invention will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 refer to Figures 1 to 12 This embodiment discloses a static experimental chamber for automatically collecting and sealing samples. (Reference) Figure 1 , Figure 2 and Figure 9 The static experimental chamber includes a chamber body 1. The bottom of the chamber body 1 has an opening for sealing and fixing to the soil. Inside the chamber body 1 are a soil sampling mechanism 2 and a soil sealing mechanism 3. The soil sealing mechanism 3 has multiple sealing containers 31 for sealing soil samples. The soil sampling mechanism 2 is used to grab soil samples and place them into the sealing containers 31 of the soil sealing mechanism 3. The chamber body 1 is also connected to a gas sampling mechanism 4, which is used to sample and preserve the gas inside the chamber body 1. Multiple sets of soil sampling mechanisms 2 and soil sealing mechanisms 3 can be installed inside the chamber body 1, each capable of sampling the soil separately.

[0033] In this embodiment, the box 1 is fixed above the soil to form a good static sealing effect. The soil sampling mechanism 2 collects soil samples into the soil sealing mechanism 3. The multiple sealing containers 31 set on the soil sealing mechanism 3 can seal multiple soil samples. The gas sampling mechanism 4 samples and preserves the gas inside the box 1. This enables the regular collection of soil samples and gas samples inside the box. Compared with manual sampling, this can effectively improve efficiency, reduce manpower, time and economic costs, and effectively avoid the impact of human sampling interference on the accuracy of sample experiments.

[0034] refer to Figures 3 to 6 The soil sampling mechanism 2 includes a moving drive component 21 and a sampling claw component 22. The fixed end of the moving drive component 21 is fixedly connected to the housing 1, and the output end of the moving drive component 21 is connected to the sampling claw component 22 to drive the sampling claw component 22 to move inside the housing 1. The lower end of the sampling claw component 22 can grasp soil samples. Specifically, the moving drive component 21 has at least two degrees of freedom of movement, such as translation in the horizontal X direction and lifting in the vertical Z direction, enabling the moving drive component 21 to drive the sampling claw component 22 to move and perform its function. In some embodiments, the moving drive component 21 may also have three degrees of freedom of movement in the X, Y, and Z directions, making the sampling range of the sampling claw component 22 larger. The lower end of the sampling claw component 22 can be inserted into the soil under the drive of the moving drive component 21 to facilitate the grasping of soil samples.

[0035] In this embodiment, the sampling claw assembly 22 is driven by the moving drive assembly 21 to move within the housing 1, so as to grab soil samples multiple times or grab soil samples from different locations and transport them to different storage containers 31 of the soil storage mechanism 3, thereby reducing the time and labor costs required for regular manual sampling.

[0036] refer to Figure 5 and Figure 6The sampling claw assembly 22 includes a sampling container 221, sampling claws 222, and an opening / closing drive mechanism 223. The sampling container 221 has an opening at its bottom. The sampling claws 222 are hinged around the opening of the sampling container 221. The fixed end of the opening / closing drive mechanism 223 is fixedly connected to the sampling container 221, and the output end of the opening / closing drive mechanism 223 is connected to the sampling claws 222 to drive them to open and close. Specifically, the opening at the bottom of the sampling container 221 is rectangular, and the sampling claws 222 are triangular. The upper end of the sampling claws 222 is horizontally hinged to the side of the bottom of the sampling container 221. The four sampling claws 222 can surround the bottom opening of the sampling container 221, and when closed, they can seal the bottom of the sampling container 221. The bottom of the sampling claws 222 is pointed, allowing them to be inserted into the soil for grasping when open.

[0037] In this embodiment, the sampling claw 222 is driven to rotate by the opening and closing drive mechanism 223, thereby opening or closing the bottom opening of the sampling container 221. When the sampling claw 222 is open, the sampling claw assembly 22 moves downward and inserts the lower part of the sampling claw 222 into the soil. Then, the sampling claw 222 is driven to close by the opening and closing drive mechanism 223, thereby grabbing the soil into the sampling container 221 for subsequent transportation.

[0038] refer to Figure 7 and Figure 8 The opening and closing drive mechanism 223 includes an opening and closing drive track seat 2231, an opening and closing drive slide plate 2232, and an opening and closing drive motor 2233. The opening and closing drive track seat 2231 is fixedly connected to the sampling container 221, the opening and closing drive slide plate 2232 is slidably connected to the opening and closing drive track seat 2231, the fixed end of the opening and closing drive motor 2233 is fixedly connected to the opening and closing drive track seat 2231, and the output end of the opening and closing drive motor 2233 is transmittedly connected to the opening and closing drive slide plate 2232 to drive the opening and closing drive slide plate 2232 to move along the opening and closing drive track seat 2231. The end of the opening and closing drive slide plate 2232 facing the sampling claw 222 is movably connected to the sampling claw 222.

[0039] Specifically, the opening and closing drive track seat 2231 is fixedly connected to the sampling container 221 via a fixed frame 2235. The upper end of the fixed frame 2235 is directly fixed to the outer wall of the sampling container 221, and the lower end of the fixed frame 2235 has a window, on which the opening and closing drive track is fixedly connected. The extension direction of the opening and closing drive track is towards the sampling claw 222, and the opening and closing drive slide plate 2232 is slidably connected to the opening and closing drive track. Therefore, the opening and closing drive slide plate 2232 can slide towards or away from the sampling claw 222. An opening and closing rack 2237 with the same extension direction is provided in the middle of the opening and closing drive slide plate 2232. An opening and closing gear 2238 is coaxially fixedly connected to the output end of the opening and closing drive motor 2233. The gear and rack 2237 mesh with each other, enabling the opening and closing drive motor 2233 to drive the opening and closing drive slide plate 2232 to move along the opening and closing drive track seat 2231. One end of the opening and closing drive slide plate 2232 is movably connected to the sampling claw plate 222. When the opening and closing drive slide plate 2232 moves toward or away from the sampling claw plate 222, it can drive the sampling claw plate 222 to close or open.

[0040] In this embodiment, the opening and closing drive motor 2233 drives the opening and closing drive slide plate 2232 to move along the opening and closing drive track seat 2231. Since one end of the opening and closing drive slide plate 2232 is movably connected to the sampling claw 222, the opening and closing drive motor 2233 can indirectly drive the sampling claw 222 to perform opening and closing movements, thereby controlling the sampling claw assembly 22 to grab or put down the soil sample.

[0041] refer to Figure 7 and Figure 8 One end of the opening / closing drive slide plate 2232 is rotatably connected to an opening / closing bearing 2234. The sampling claw is magnetic, and the opening / closing bearing 2234 and the sampling claw 222 are magnetically attracted and can roll on the sampling claw 222. In this embodiment, the opening / closing bearing 2234 and the sampling claw 222 are connected by magnetic attraction, and the opening / closing bearing 2234 can roll on the sampling claw 222, thereby realizing the movable connection between the opening / closing drive slide plate 2232 and the sampling claw 222.

[0042] In some other embodiments, the opening and closing drive mechanism 223 may be a motor and a component connected to the motor in a transmission. The output shaft of the motor is directly connected to the part where the sampling claw 222 is hinged to the sampling container 221 through the component connected in a transmission. By driving the hinge part of the sampling claw 222 to rotate, the rotation of the sampling claw 222 is directly realized.

[0043] In other embodiments, one end of the opening / closing drive slide plate 2232 can be slidably connected to the sampling claw 222 via a slider. For example, a slide rail is provided on the outer side of the sampling claw 222, and the slider is slidably connected to the slide rail. Simultaneously, the slider is rotatably connected to the opening / closing drive slide plate 2232. This also enables the opening and closing of the sampling claw 222 by the opening / closing drive slide plate 2232.

[0044] refer to Figure 9 The sealing container 31 includes a sealing cylinder 311, a cover plate 312, and an elastic tightening member 313. The upper end of the sealing cylinder 311 has an opening. Multiple cover plates 312 are slidably connected to the opening of the sealing cylinder 311 from the center to the periphery. The elastic tightening member 313 is connected to each cover plate 312 so that each cover plate 312 closes the opening of the sealing cylinder 311. The opening and closing drive slide plate 2232 can move outward to drive the sampling claw 222 to open so that the soil sample in the sampling container 221 falls out. At the same time, the other end of the opening and closing drive slide plate 2232 can push the cover plate 312 to open so that the soil sample falls into the sealing cylinder 311.

[0045] Specifically, the lower end of the sealing cylinder 311 is inverted conical, and a fixing bolt 32 is provided in the middle of the sealing cylinder 311, which can fix the sealing cylinder 311 to the inner wall of the box 1. There are four cover plates 312, the same number as the sampling claws 222, and their distribution positions correspond one-to-one. The four cover plates 312 cover the upper opening of the sealing cylinder 311 in four equal parts. A circular groove is opened on the outer arc surface of each cover plate 312, and an elastic tightening member 313 is embedded in the circular groove. The elastic tightening member 313 can be an elastic rope or a clamping spring. Under the action of the elastic tightening member 313, when there is no other external force, the cover plate 312 can be closed towards the center to seal the sealing cylinder 311.

[0046] In this embodiment, the cover plate 312 seals the opening of the cylinder under the action of the elastic tightening member 313, which can effectively seal the storage container 31. When the sampling claw assembly 22 grabs the soil sample and moves it above the storage container 31, one end of the opening and closing drive slide plate 2232 pulls the sampling claw 222 to open, and at the same time, the other end of the opening and closing drive slide plate 2232 pushes the cover plate 312 to open, transferring the soil sample into the storage cylinder 311.

[0047] refer to Figure 9The sealing cylinder 311 has a sealing groove 3111 at its upper end, and a sealing rail 3121 at its lower end. The sealing rail 3121 is slidably connected to the sealing groove 3111. A force-bearing column 3122 is provided at the upper end of the cover plate 312, which abuts against one end of the opening / closing drive slide plate 2232. In this embodiment, the sealing groove 3111 and the sealing rail 3121 guide the cover plate 312 in a sliding manner, and the force-bearing column 3122 facilitates pushing using the opening / closing drive slide plate 2232. (Reference) Figure 10 and Figure 11 The sealing chute 3111 and the sealing rail 3121 extend radially along the opening section of the sealing cylinder. When the sampling claw assembly 22 opens the sampling claw 222 above the center of the sealing container 31, it can simultaneously push the four cover plates 312 to open in all directions.

[0048] refer to Figure 12 The gas sampling mechanism 4 includes a gas supply pipe 41, multiple gas supply valves 42, and multiple gas collection bottles 43. The inlet end of the gas supply pipe 41 is connected to the housing 1, and the gas supply pipe 41 has multiple outlet ends, each connected to a gas collection bottle 43. Each gas supply valve 42 is located at a different outlet end of the gas supply pipe 41. Specifically, the gas supply pipe 41 includes a main pipe and branch pipes. The main pipe is connected to the air inside the housing 1, and the branch pipes are connected to the main pipe. Each branch pipe is equipped with a gas supply valve 42, which can be a solenoid valve connected to a controller to control the connection of each branch pipe. The outlet of each branch pipe is connected to a different gas collection bottle 43, thereby enabling the periodic collection of gas from the housing 1 and its collection in the laboratory for relevant measurement experiments.

[0049] In this embodiment, the gas collecting bottle is initially in a vacuum state. Since the gas inside the box has a certain pressure, under the influence of the pressure difference, opening the gas supply valve 42 allows the gas in the box 1 to flow to the gas collecting bottle 43 for storage through the gas supply pipe 41. By setting multiple gas supply valves 42 and multiple gas collecting bottles 43, the gas in the box 1 can be collected and stored multiple times, reducing labor costs.

[0050] Example 2 refer to Figures 1 to 12 Similar to Example 1, this embodiment discloses a static experimental chamber for automatically collecting and sealing samples.

[0051] refer to Figure 3 and Figure 4In this embodiment, the motion drive assembly 21 includes a translation motor 211, a translation transmission module 212, a lifting motor 213, and a lifting transmission module 214. The output end of the translation motor 211 is connected to the input end of the translation transmission module 212 to drive the output end of the translation transmission module 212 to translate. The output end of the translation transmission module 212 is connected to the lifting transmission module 214. The output end of the lifting motor 213 is connected to the input end of the lifting transmission module 214 to drive the output end of the lifting transmission module to move up and down. The sampling claw assembly 22 is connected to the output end of the lifting transmission module.

[0052] In this embodiment, the translation motor 211 drives the translation transmission module 212, and the lifting motor 213 drives the lifting transmission module 214. The translation transmission module 212 drives the lifting transmission module 214 to move, and the lifting transmission module 214 drives the sampling claw assembly 22 to move up and down, thereby realizing the horizontal and vertical movement of the sampling claw assembly 22 to facilitate the collection and transportation of soil samples.

[0053] Specifically, in this embodiment, reference is made to... Figure 3 and Figure 4 The translational transmission module 212 includes an upper rail plate 2121, a lower rail plate 2122, a flat gear plate 2123, an outer guide bearing 2124, an inner guide bearing, a stabilizing ring 2125, and a translational gear 2126. The upper rail plate 2121 and the lower rail plate 2122 are arranged in parallel and are both fixedly connected to the inner sidewall of the housing 1. The flat gear plate 2123 is fixedly connected to the upper side of the lower rail plate 2122. The lower rail plate 2122 has control grooves 2127 on both sides of the flat gear plate 2123, and the upper rail plate 2121 also has control grooves 2127. The outer guide bearing 2124 is disposed between the upper rail plate 2121 and the lower rail plate 2122, and the outer ring of the outer guide bearing 2124 is rolled in the control grooves 2127 of the upper rail plate 2121 and the lower rail plate 2122.
