DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0025] Please refer to Figures 1-4 As shown in the figure, a kind of field wheat canopy ethylene collection device, comprising: collecting cover 1, the bottom end of collecting cover 1 is equipped with arc-shaped inner hollow plate 2, arc-shaped inner hollow plate 2 is equipped with first annular column plate 3 and second annular column plate 4 respectively on the inside and outside, the bottom end of the inner side wall of collecting cover 1 is equipped with movable groove 5 in vertical direction, movable block 6 is installed in the side wall of first annular column plate 3, movable groove 5 and movable block 6 are adapted, adjustable anti-drop assembly is installed in the bottom end of collecting cover 1.

[0026] Further, the anti-falling assembly includes an anti-falling block 7, a through slot 8, a limiting rod 9 and a first spring 10. The anti-falling block 7 is installed at the end of the movable slot 5. The through slot 8 penetrates the anti-falling block 7. The limiting rod 9 is partially located in the through slot 8. The first spring 10 is arranged in the through slot 8 and connected between the collecting cover 1 and the limiting rod 9. The diameter of the limiting rod 9 at the end outside the through slot 8 is larger than the inner diameter of the through slot 8.

[0027] Through the above technical solution:

[0028] In use, the collecting cover 1 is placed above the arc-shaped hollow plate 2. The first annular column plate 3 is arranged inside the collecting cover 1, and the second annular column plate 4 is arranged outside the collecting cover 1. The innovative nested design not only ensures the stable connection between the collecting cover 1 and the arc-shaped hollow plate 2, but also lays a solid foundation for subsequent sealing operation. Through this structure, the device can effectively resist external interference and maintain overall stability when used in the field, avoiding displacement or damage caused by wind or mechanical impact.

[0029] Next, the anti-falling block 7 is rotated and moved to the end of the movable slot 5. At this time, the first spring 10 uniformly pulls the limiting rod 9 through its preset spring force, so that the limiting rod 9 stably presses the anti-falling block 7, preventing the anti-falling block 7 from being randomly moved during use, thereby effectively preventing the movable block 6 from falling out of the movable slot 5. This design ensures the reliability of the entire device in the complex environment of the field, avoiding the decrease of collection efficiency or the failure of the device caused by loose or falling parts.

[0030] The assembled device is entirely covered over the wheat canopy. At this time, the arc-shaped hollow plate 2 is in direct contact with the ground. Due to its own gravity, the arc-shaped hollow plate 2 will naturally sink in the field and form a close physical contact with the ground. This design utilizes the principle of gravity to ensure the sealing between the device and the ground, effectively preventing the infiltration of external air and the leakage of ethylene gas, providing a guarantee for accurately collecting the ethylene gas released by the wheat canopy.

[0031] The field sand is filled in the arc-shaped hollow plate 2. This step not only forms a physical barrier between the collecting cover 1 and the first annular column plate 3 and the arc-shaped hollow plate 2, isolating part of the external air, but also further enhances the sealing of the collecting cover 1, effectively reducing the escape of ethylene gas. The filling of sand has the following multiple benefits:

[0032] Stability enhancement: The sand increases the weight of the bottom of the collecting cover 1, lowers the overall center of gravity, and makes the device less likely to tip over in the field, especially in windy conditions. The device can maintain stability and is convenient to use: The sand is taken from the field, which is convenient to operate and does not require the carrying of other materials, reducing the cost and difficulty of operation.

[0033] Environment-friendly: using field sand as filling material, avoiding the potential impact of introducing foreign materials on the field environment, meeting environmental protection requirements;

[0034] Due to the movable assembly between the arc-shaped hollow plate 2 and the collection cover 1, the arc-shaped hollow plate 2 has the space to move up and down, and in rainy weather or when the ground is wet and soft, the arc-shaped hollow plate 2 can automatically follow the ground subsidence, realize self-adjustment, and maintain sealing. This design ensures the adaptability and reliability of the device under different field conditions, whether in dry or wet soil conditions, it can maintain good sealing performance to ensure effective collection of ethylene gas;

[0035] When it is necessary to disassemble the collection cover 1 and the arc-shaped hollow plate 2, only need to pull out the limiting rod 9 outwardly, and rotate the anti-dropping block 7 to move the anti-dropping block 7 away from the end of the movable slot 5, which makes the movable block 6 easily move out of the movable slot 5, thereby realizing the separation of the collection cover 1 and the arc-shaped hollow plate 2. This design has the following advantages:

[0036] Easy to clean: after disassembly, the device parts can be easily cleaned and maintained, ensuring the reliability and stability of long-term use;

[0037] Prolong the service life: regular disassembly and cleaning can effectively prevent component aging or clogging, prolong the service life of the device;

[0038] Improve work efficiency: convenient disassembly and maintenance process reduces operation time, improves work efficiency, and makes field work more efficient.

[0039] Please refer to Figures 1-5 As shown in the figure, the inner top end of the collection cover 1 is provided with a conical cover 11, the air inlet end of the conical cover 11 is provided with a filter screen plate 12, one side of the filter screen plate 12 is provided with a plurality of elastic components, and the air outlet end of the conical cover 11 is provided with a gas collection assembly.

[0040] Further, the sidewall of the collection cover 1 is provided with a motor 13, the output end of the motor 13 is connected with a rotating shaft 14, the rotating shaft 14 extends into the inside of the collection cover 1, and the plurality of elastic components are uniformly arranged around the outer periphery of the rotating shaft 14;

[0041] Further, the elastic component includes an elastic rod 16, an elastic ball 17 and a second spring 18, the elastic rod 16 is connected to the outer wall of the rotating shaft 14, the elastic ball 17 is arranged at the end of the elastic rod 16 away from the rotating shaft 14, and the second spring 18 is connected between the elastic rod 16 and the elastic ball 17;

[0042] The inner wall of the conical cover 11 is provided with an open box cover 15, and the open end of the open box cover 15 faces the filter screen plate 12. A plurality of elastic assemblies are arranged inside the open box cover 15, and the total length between the elastic rod 16 and the elastic ball 17 is greater than the straight line distance from the rotating shaft 14 to the inner wall of the open box cover 15.

[0043] Through the above technical solutions:

[0044] In use, the filter screen plate 12 is installed at the air inlet end of the conical cover 11, which is particularly important in the complex field environment. Due to the complex and changeable field environment, dust, particulate matter and other impurities are easily generated. The filter screen plate 12 plays a crucial role in this regard, as it can efficiently filter the air entering the conical cover 11, effectively removing dust, impurities and other particulate matter, and ensuring the purity of the collected ethylene gas. This filtering design not only prevents impurities from entering the device, but also avoids interference with subsequent gas treatment and analysis processes, thereby ensuring the accuracy and reliability of the entire collection process.

[0045] Over time, the filter screen plate 12 will gradually accumulate dust during continuous operation, which will gradually block the filter holes of the filter screen plate 12, reducing its filtering efficiency and affecting the overall performance of the device. At this time, the motor 13 can drive the elastic assembly installed on the outer periphery of the rotating shaft 14 to rotate, and the elastic rod 16, the elastic ball 17 and the second spring 18 rotate together with the rotating shaft 14. Since the total length between the elastic rod 16 and the elastic ball 17 is greater than the straight line distance from the rotating shaft 14 to the inner wall of the open box cover 15, the elastic rod 16 assumes a curved state inside the open box cover 15. When the elastic rod 16 and the elastic ball 17 move to the open end of the open box cover 15, the elastic rod 16 will quickly change from a curved state to a straight state. In the straight state, the elastic ball 17 will knock the filter screen plate 12, which can effectively knock off the dust on the filter screen plate 12, achieving automatic cleaning. The second spring 18 plays a key role in this process, further enhancing the elasticity between the elastic rod 16 and the elastic ball 17, making the knocking action more powerful and the cleaning effect more significant.

[0046] Through the periodic knocking of the elastic assembly, the dust on the filter screen plate 12 is effectively removed, ensuring the durability and stability of the filtering effect. This automatic cleaning mechanism reduces the need for manual maintenance, reduces the difficulty and labor intensity of operation, and improves the automation level of the device.

[0047] Further, please refer to Figure 1 and Figure 3As shown, the gas collecting assembly includes a first gas duct 19, a gas pump 20, a second gas duct 21 and a gas collecting balloon 22, the first gas duct 19 is connected to the gas outlet end of the conical cover 11, the gas pump 20 is installed at the gas outlet end of the first gas duct 19, the second gas duct 21 is connected to the gas outlet end of the gas pump 20, and the gas collecting balloon 22 is installed at the gas outlet end of the second gas duct 21.

[0048] Specifically, during the gas collecting stage of the wheat canopy ethylene collection device in the field, the gas pump 20 is first started as the core power source, which generates negative pressure through the first gas duct 19 to efficiently extract the ethylene-containing gas in the collecting cover 1 and transport it to the gas pump 20 along the first gas duct 19; then, the gas pump 20 transports the gas to the gas collecting balloon 22 through the second gas duct 21, the gas collecting balloon 22 is made of high air-tightness material to ensure that the gas does not leak and guarantee the accuracy of subsequent analysis and processing; during the entire gas collecting process, the gas pump 20 continuously and stably operates, the gas duct remains unobstructed, the capacity change of the gas collecting balloon 22 is monitored in real time, and it is replaced or emptied in time to maintain the continuity and stability of the gas collecting process; in addition, by reasonably selecting the gas pump 20 and optimizing the design of the gas duct and the gas collecting balloon 22, the gas collecting efficiency is improved, the purity and storage safety of the ethylene gas are ensured, and reliable guarantee is provided for subsequent gas analysis and processing.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
