Description

Technical Field

[0001] The utility model relates to the technical field of plant information collection and detection, in particular to a device for collecting and detecting chemical information of plant volatiles. Background Art

[0002] Plant volatiles are chemical substances released by plants into the surrounding environment, usually having specific odors and chemical compositions. These volatiles have multiple important functions in the plant kingdom. Plant volatiles are usually composed of multiple compounds, including monoterpenes, phenols, aldehydes, ketones, alcohols, etc. Their composition and content may vary due to factors such as plant species, growth environment, and physiological state. Studying plant volatiles is of great significance for understanding plant ecology, plant-insect interactions, agricultural production, etc. Plant volatiles can provide information about plant-plant interactions, the relationships between plants and other organisms, and biological activities in the ecosystem. By collecting and detecting the chemical information of plant volatiles, we can deeply understand the roles and functions of plants in the ecosystem and their impacts on the environment.

[0003] Existing devices for collecting and detecting plant volatiles usually use an adsorption material or device that contacts the plant surface to adsorb volatiles, and then the volatiles can be separated, detected, and identified by an instrument to obtain the chemical composition and structural information of the volatiles.

[0004] However, traditional devices for collecting and detecting plant volatiles may not have high selectivity and sensitivity for volatiles, and require a long analysis time. When adsorbing, gases and impurities that easily enter the detector may occur. Therefore, a device for collecting and detecting chemical information of plant volatiles is proposed to solve the above problems. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a device for collecting and detecting chemical information of plant volatiles, aiming to improve the problems of insufficient sensitivity and easy disorderly adsorption directly in the air in the prior art.

An air pump 5 is fixedly connected to the outer wall of the conduit 6. One end of the air pump 5 is fixedly connected to a chemical sensor 4. A recording tablet 3 is arranged on one side of the outer wall of the chemical sensor 4. A support assembly is arranged at the bottom of the chemical sensor 4;

[0032] Specifically, by placing the plant on the top of the placement base 8 and then covering it with the transparent cylinder 7, only the volatiles of the plant to be detected are inside. At the same time, the transparent body allows the detector to directly observe the plant. Then, pull the sliding column 10 to drive the clamping block 14 to move through the sliding column 10, compress the spring 12. Place the placement rack 15 inside the fixing frame 9 through the grip 13. Release the sliding column 10, and the clamping block 14 is placed inside the placement rack 15 for clamping through the spring 12. Then start the air pump 5 to adsorb the internal gas, and the gas is transported through the conduit 6. The dust impurities in the volatiles are filtered through the filter screen 17. Filtering the volatiles can remove impurities and interfering substances in the air, making the detection results more accurate and reliable. This can avoid interference from other compounds, thereby improving the accuracy and reliability of the detection. Then, it is introduced into the chemical sensor 4 through the conduit 6 for detection. At the same time, the detection inside the chemical sensor 4 is recorded in real time through the recording tablet 3. Real-time recording can provide immediate monitoring data, enabling users to respond and adjust in a timely manner, improving efficiency, strengthening data analysis and decision support, and having the function of historical traceability. It is a very effective data recording and management method.

[0033] Referring toFigure 1 The support assembly includes a support column 1 and a tabletop 2. The top of the tabletop 2 is fixedly connected to the bottom of the chemical sensor 4, and the top of the support column 1 is fixedly connected to the bottom of the tabletop 2;

[0034] Specifically, the recording plate 3 and the chemical sensor 4 are supported by the support column 1 and the tabletop 2, which have high reliability and stability.

On the top of the slide rail 25, a first fixed column 20 is fixedly connected. The outer wall of the first fixed column 20 is slidably connected inside the first limiting groove 22. On the top of the slide rail 25, a second fixed column 21 is fixedly connected. The outer wall of the second fixed column 21 is slidably connected inside the second limiting groove 23;

[0036] Specifically, start the motor 28. The motor 28 drives the worm 18 to move. By utilizing the meshing between the worm 18 and the worm wheel 27, the transmission of large torque and moment is ensured. Thus, the turntable 24 is driven to rotate by the worm wheel 27. Then, the second limiting groove 23 is driven to rotate by the turntable 24. Then, the second fixed column 21 is driven to move by the second limiting groove 23. Subsequently, the first fixed column 20 is driven to move by the second fixed column 21. Thereby, transparent cylinders 7 of different sizes can be fixed, ensuring that the plant container is stably placed inside it, avoiding the plant from swaying or tilting due to movement or shaking, thus affecting the growth and display effect of the plant. At the same time, it is convenient to take and place the transparent cylinder 7 for later maintenance. Transparent cylinders 7 with different diameters can also be fixed to place and detect plants of different sizes.

[0037] Working principle: Place the plant on top of the base 8, cover the transparent cylinder 7, then start the motor 28. Drive the fixedly connected worm 18 to rotate through the motor 28, then drive the meshing-connected worm gear 27 to rotate through the worm 18, and then drive the fixedly connected turntable 24 to rotate through the worm gear 27. At the same time, drive the second limiting groove 23 opened inside the turntable 24 to rotate, so as to drive the slidably connected first fixed column 20 to move in the slidably connected first limiting groove 22 through the second limiting groove 23. At the same time, drive the fixedly connected slide rail 25 to slide inside the slidably connected fixed block 26 through the first fixed column 20 to fix the transparent cylinder 7. Then start the air pump 5 to adsorb the gas inside the transparent cylinder 7 and transport it through the conduit 6. Then transport it through the filter screen 17 inside the fixing frame 9 to filter the impurities in the gas, and then transport it through the conduit 6 to the fixedly connected chemical sensor 4 for detection. At the same time, the detection of the chemical sensor 4 is recorded in real time through the recording tablet 3. Then, the sliding column 10 can be pulled to drive the clamping block 14 to move and compress the spring 12 at the same time. Then pull the handle 13 to drive the fixedly connected placement rack 15 to move, and then drive the fixedly connected slider 16 to slide inside the slidably connected fixing frame 9 through the placement rack 15 to take it out and clean the internal filter screen 17.
