Description

Technical Field

[0001] This utility model relates to the field of plant maintenance technology, specifically to a plant rhizosphere aeration assessment structure. Background Technology

[0002] The aeration of the plant rhizosphere directly affects root respiration, nutrient absorption efficiency, and microbial activity, thus having a crucial impact on plant growth, development, and stress resistance. In agricultural planting, forestry cultivation, and horticultural maintenance, accurately assessing plant rhizosphere aeration is an important prerequisite for optimizing planting management measures and improving plant growth quality.

[0003] Currently, existing methods for detecting rhizosphere aeration suffer from problems such as complex operation, poor sealing of the testing environment, and low data accuracy. For example, a common method involves pre-drilling a deep hole in the soil around the rhizosphere, then inserting a pipe into the hole to extract air, and measuring the gas flow rate to reflect rhizosphere aeration. However, during the testing process, the device cannot effectively isolate the rhizosphere testing area from the influence of external air, resulting in significant errors in the measured gas flow rate data and failing to provide a reliable reference for plant cultivation and management. Utility Model Content

[0004] To address the above issues, this invention proposes a structure for assessing plant rhizosphere aeration. An air pump inflates an airbag, creating a closed rhizosphere testing environment at the bottom of the extraction tube, effectively preventing outside air from entering the testing area and interfering with the test data.

[0005] A plant rhizosphere aeration assessment structure includes a detection host and an extraction pipe connected to the detection host. The detection host contains a detection pipe, an inflation pipe, and an extraction pump. The detection pipe is connected between the air inlet of the extraction pump and the extraction pipe. A gas flow meter is installed inside the detection pipe. An inflation bladder is fitted on the outer wall of the bottom end of the extraction pipe. An air bladder tube connected to the inflation pipe is attached to the inflation bladder. The detection host has an exhaust port and a switching valve. The switching valve allows the inflation pipe and the exhaust port to be connected to the air outlet of the extraction pump. The detection host also has a display screen for displaying detection data.

[0006] Furthermore, the switching valve consists of a valve body and a valve core. The valve body has a valve cavity, and the valve body has a valve inlet pipe connected to the outlet of the air pump and communicating with the valve cavity. The valve body also has a first valve tube and a second valve tube, respectively corresponding to the inflation pipe and the exhaust port and communicating with the valve cavity. The valve core is rotatably positioned within the valve cavity, and its rotation switches between the first and second valve tubes, allowing one to communicate with the valve inlet pipe. Specifically, the valve core body is sealed to the inner wall of the valve cavity. When the first valve tube is connected to the valve inlet pipe, the inflation pipe is connected to the outlet of the air pump, and the passage between the air pump outlet and the exhaust port is closed, indicating an "inflation-sealed state." When the second valve tube is connected to the valve inlet pipe, the passage between the air pump outlet and the exhaust port is opened, and the passage between the air pump outlet and the inflation pipe is closed, indicating a "vacuum detection" state.

[0007] Furthermore, the valve inlet pipe, the first valve pipe, and the second valve pipe are arranged in a "T" shape, and the valve core is equipped with a "T"-shaped three-way conversion pipe. Specifically, by using a "T"-shaped three-way conversion pipe, after the test is completed, the valve core can be rotated to switch the first valve pipe and the second valve pipe, allowing the inflation bag to deflate so that the suction pipe can be removed from the deep hole.

[0008] Furthermore, a partition plate is installed inside the suction pipe to form a secondary pipe. The airbag tube is installed along the secondary pipe, and the inflatable airbag has an inflation nozzle located inside the secondary pipe. The bottom end of the airbag tube is connected to the inflation nozzle. The airbag tube is located inside the secondary pipe to protect the airbag tube and prevent it from being scratched by sharp stones or debris in the soil when the suction pipe is inserted into the deep hole.

[0009] Furthermore, a scale is provided on the outer wall of the suction tube, running along its length. The scale reflects the insertion depth of the suction tube and facilitates the assessment of plant rhizosphere aeration at different depths.

[0010] Furthermore, the testing unit is equipped with a connection interface, and the air extraction pipe is equipped with a quick connector corresponding to the connection interface. Even further, the connection interface is equipped with a testing port and an inflation port for connecting the testing pipe and the inflation pipe respectively. The quick connector is equipped with a connecting pipe corresponding to the testing port. The top of the airbag tube extends from the top of the quick connector, and the top edge of the airbag tube is equipped with a sealing plug for a tight connection with the inflation port.

[0011] Furthermore, the main testing unit is equipped with a controller connected to the air pump, gas flow meter, and display screen. The switching valve is an electrically controlled valve connected to the controller. The controller can control the movement of the valve core inside the switching valve to switch the interface connection status, making operation simple and convenient.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By inserting the suction tube into the rhizosphere soil, the air pump can be used to inflate the air bladder before testing. After the air bladder expands, it cooperates with the soil to form a closed rhizosphere testing environment at the bottom of the suction tube, effectively preventing outside air from entering the testing area and interfering with the testing data, and significantly improving the accuracy of gas flow rate detection. The device has a compact overall structure, and the switching between the "inflation and sealing" and "suction and testing" states can be quickly achieved through the switching valve, without the need for complicated manual sealing operations.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] like Figure 1-2As shown, a plant rhizosphere aeration assessment structure includes a detection host 1 and an air extraction pipe 2 connected to the detection host 1. The detection host 1 is equipped with a detection pipe 3, an inflation pipe 4, and an air extraction pump 5. The detection pipe 3 is connected between the air inlet of the air extraction pump 5 and the air extraction pipe 2. A gas flow meter 6 is installed inside the detection pipe 3. An inflation bladder 7 is fitted on the outer wall of the bottom end of the air extraction pipe 2. An air bladder tube 8 connected to the inflation pipe 4 is connected to the inflation bladder 7. The detection host 1 is equipped with an exhaust port 9 and a switching valve 10. The switching valve 10 can connect either the inflation pipe 4 or the exhaust port 9 to the air outlet of the air extraction pump 5. The detection host 1 is also equipped with a display screen 11 for displaying detection data. This invention inserts the extraction tube 2 into the rhizosphere soil. Before testing, the extraction pump 5 inflates the air bag 7, causing the air bag 7 to expand and cooperate with the soil to form a closed rhizosphere testing environment at the bottom of the extraction tube 2. This effectively prevents outside air from entering the testing area and interfering with the testing data, significantly improving the accuracy of gas flow rate detection. The device has a compact overall structure, and the switching valve 10 can quickly switch between the "inflated sealing" and "extraction testing" states without the need for complicated manual sealing operations.

[0021] like Figure 3 As shown, in this embodiment, the switching valve 10 is composed of a valve body 12 and a valve core 13. The valve body 12 has a valve cavity inside. The valve body 12 is provided with a valve inlet pipe 14 that is connected to the air outlet of the air pump 5 and communicates with the valve cavity. The valve body 12 is also provided with a first valve pipe 15 and a second valve pipe 16 that correspond to the air filling pipe 4 and the air exhaust port 9 respectively and communicate with the valve cavity. The valve core 13 is rotatably disposed in the valve cavity. The rotation of the valve core 13 switches the first valve pipe 15 and the second valve pipe 16 to communicate with the valve inlet pipe 14. Specifically, the main body of the valve core 13 is sealed to the inner wall of the valve cavity. When the first valve pipe 15 is connected to the valve inlet pipe 14, the inflation pipe 4 is connected to the outlet of the vacuum pump 5, and the channel between the outlet of the vacuum pump 5 and the exhaust hole is closed. At this time, it is in the "inflation and sealing state". When the second valve pipe 16 is connected to the valve inlet pipe 14, the channel between the outlet of the vacuum pump 5 and the exhaust hole is opened, and the channel between the outlet of the vacuum pump 5 and the inflation pipe 4 is closed. At this time, it is in the "vacuum detection" state.

[0022] In this embodiment, the valve inlet pipe 14, the first valve pipe 15, and the second valve pipe 16 are arranged in a "T" shape, and the valve core 13 is provided with a "T"-shaped three-way conversion pipe 17. Specifically, by using the "T"-shaped three-way conversion pipe 17, after the test is completed, the valve core 13 can be rotated to switch the first valve pipe 15 and the second valve pipe 16 to conduct, so that the inflatable airbag 7 can be deflated to facilitate the removal of the suction pipe 2 from the deep hole.

[0023] In this embodiment, a partition plate 18 is provided inside the suction pipe 2 to form a secondary pipe 19. The airbag tube 8 is arranged along the secondary pipe 19, and the inflatable airbag 7 is provided with an inflation nozzle located inside the secondary pipe 19. The bottom end of the airbag tube 8 is connected to the inflation nozzle. The airbag tube 8 is located inside the secondary pipe 19 to protect it from being scratched by sharp stones, debris, etc. in the soil when the suction pipe 2 is inserted into the deep hole.

[0024] In this embodiment, a scale 20 is provided on the outer wall of the air extraction tube 2, running along its body. The scale 20 can reflect the insertion depth of the air extraction tube 2, and at the same time facilitates the detection and evaluation of the aeration of the plant rhizosphere at different depths.

[0025] like Figure 4 As shown, in this embodiment, the detection host 1 is provided with an interface 24, and the suction pipe 2 is provided with a quick connector 21 corresponding to the interface 24. Furthermore, the interface 24 is provided with a detection port and an inflation port respectively connecting to the detection pipe 3 and the inflation pipe 4. The quick connector 21 is provided with a connecting pipe 22 corresponding to the detection port. The top end of the airbag tube 8 extends from the top end of the quick connector 21, and the edge of the top end of the airbag tube 8 is provided with a sealing plug 23 that seals tightly with the inflation port. Specifically, the interface 24 and the quick connector 21 adopt a plug-in detachable connection structure, which facilitates the replacement of suction pipes 2 of different lengths and improves the portability of the device.

[0026] In this embodiment, the detection host 1 is also equipped with a controller 25 connected to the air pump 5, the gas flow meter 6, and the display screen 11. The switching valve 10 is an electric control valve connected to the controller 25. The controller 25 can control the movement of the valve core 13 inside the switching valve 10 to switch the interface connection state, which is simple and convenient to operate.

[0027] The working principle of this utility model is as follows: First, a deep hole is drilled at the root zone to be tested. After the air extraction tube 2 is inserted to the depth to be tested, the switching valve 10 connects the air bladder tube 8 with the air outlet of the air extraction pump 5. The air extraction pump 5 is started to extract air from the deep hole and inflate the air bladder 7, causing the air bladder to expand and seal the gap between the air extraction tube 2 and the inner wall of the deep hole, thus creating a closed environment at the opening of the air extraction tube 2. The switching valve 10 switches to close the channel between the air bladder tube 8 and the air outlet of the air extraction pump 5. At the same time, the channel between the air outlet of the air extraction pump 5 and the exhaust port 9 is connected. The air extraction pump 5 continues to extract air, and the gas flow meter 6 detects the gas flow rate and displays it on the display screen 11. After the reading detected by the gas flow meter 6 stabilizes, the gas flow rate is recorded as the test data. The larger the test data, the better the root zone aeration, and vice versa.

[0028] The beneficial effects of this utility model are as follows: By inserting the air extraction tube 2 into the rhizosphere soil, the air pump 5 can be used to inflate the air bag 7 before testing. After the air bag 7 expands, it cooperates with the soil to form a closed rhizosphere testing environment at the bottom of the air extraction tube 2, effectively preventing outside air from entering the testing area and interfering with the testing data, and significantly improving the accuracy of gas flow rate detection. The overall structure of the device is compact, and the switching valve 10 can quickly switch between the two states of "inflated sealing" and "air extraction testing", without the need for complicated manual sealing operations.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
