Description

Technical Field

[0001] This utility model relates to drought monitoring technology, specifically to a device for monitoring drought conditions in corn kernels. Background Technology

[0002] The impact of drought and water shortage on maize growth is particularly pronounced during the grain-filling stage, a critical period for yield and quality formation. Prolonged water shortage severely inhibits leaf photosynthesis, hindering assimilate synthesis and translocation. Insufficient carbohydrate supply leads to incomplete grain filling, manifesting as reduced grain weight, grain shrinkage, and even abortion. Simultaneously, water stress accelerates plant senescence, causes premature leaf yellowing, shortens the grain-filling period, and further reduces dry matter accumulation. Furthermore, water shortage can disrupt nutrient metabolic balance, affecting starch and protein synthesis and deposition, resulting in decreased grain quality. Ultimately, drought will cause a reduction in the number of grains per ear, a significant decrease in thousand-grain weight, and substantial yield loss, potentially leading to total crop failure. Therefore, ensuring adequate water supply during the grain-filling stage is crucial for high-yield and high-quality maize production.

[0003] Chinese invention patent CN116608373A discloses a field monitoring device for drought resistance of corn and wheat, relating to the technical field of corn and wheat planting and solving the problem of monitoring drought resistance in corn and wheat. It includes a first support column, a second support column, a mounting plate, and monitoring instruments. The second support column is positioned above the first support column, and the top of the second support column is bolted to the mounting plate. Monitoring instruments are mounted on both sides of the mounting plate. The device also includes a fixing plate connected to the top of the mounting plate, the front surface of which is connected to a connecting plate, and a solar panel is mounted on the front side of the connecting plate. A bidirectional telescopic rod is also included. The output end of the bidirectional telescopic rod is fixed to a sliding ball, and the sliding ball and the connecting groove on the rear surface of the solar panel are slidably connected. This allows the angle of the solar panel to be adjusted via the bidirectional telescopic rod during use, enabling the solar panel to better receive sunlight and improving the flexibility of the device.

[0004] Existing corn and wheat drought resistance monitoring devices can only monitor the growth environment of corn crops. However, corn kernels are covered by a coating, and existing monitoring devices cannot specifically monitor the growth microenvironment of the kernels in the corn ear. This leads to discrepancies between the collected data and the actual data, necessitating improvements to the existing monitoring devices. Utility Model Content

[0025] Example 1:

[0026] This utility model provides a device for monitoring drought damage in corn kernels, comprising:

[0027] The detection cone 1 includes a housing 11 and a cone tube 12 connected to the housing 11. A connection hole 13 is provided on one end surface of the cone tube 12 near the housing 11. A microenvironment sensor 120 is connected inside the housing 11. The microenvironment sensor 120 communicates with the outside through the connection hole 13. A reinforcement component for strengthening the connection strength of the cone tube 12 is provided inside the housing 11.

[0028] The detector 3 has a motherboard 31 and a battery 33 connected inside. The detector 3 has a probe 32 that is electrically connected to the motherboard 31. The probe 32 can be inserted into the soil to monitor the soil environment.

[0029] Connecting wire 2 is used to electrically connect the probe cone 1 and the detector 3.

[0030] As can be seen from the above, by setting up the probe cone 1, the detector 3 and the connecting line 2 connecting the two, the user can insert the probe cone 1 from the middle of the side of the corn ear. After the cone tube 12 penetrates the coating and is stably inserted into the kernel, the connecting hole 13 connects the cavity between the coating and the kernel of the ear. At this time, the microenvironment sensor 120 is connected to the cavity, and then the cavity is monitored in real time so that the user can obtain accurate data on the growth environment of the corn kernel in real time.

[0031] The reinforcement assembly includes a knob 14 rotatably connected to the outer casing 11, a lead screw 15 fixedly connected to the knob 14, and a slider 16 threadedly connected to the lead screw 15. The end of the lead screw 15 is rotatably connected to the inner wall of the tapered tube 12. A side groove 17 is provided on the side wall of the tapered tube 12. A limiting rod 18 is connected to the inner wall of the side groove 17. A rotating plate 19 is provided inside the side groove 17. A long groove for accommodating the limiting rod 18 is provided on the rotating plate 19. The upper end of the rotating plate 19 is hinged to the slider 16.

[0032] As can be seen from the above, after the user inserts the conical tube 12 into the corn cob, the knob 14 can be rotated to drive the lead screw 15 to rotate. The rotating lead screw 15 drives the slider 16 to slide inside the conical tube 12. The sliding slider 16 will drive one end of the rotating plate 19 to move, thereby causing the rotating plate 19 to rotate around the limiting rod 18. The rotating plate 19 will be inserted into the corn cob, enhancing the connection stability between the conical tube 12 and the corn cob.

[0033] Example 2:

[0034] This utility model provides a device for monitoring drought damage in corn kernels, comprising:

[0035] The detection cone 1 includes a housing 11 and a cone tube 12 connected to the housing 11. A connection hole 13 is provided on one end surface of the cone tube 12 near the housing 11. A microenvironment sensor 120 is connected inside the housing 11. The microenvironment sensor 120 communicates with the outside through the connection hole 13. A reinforcement component for strengthening the connection strength of the cone tube 12 is provided inside the housing 11.

[0036] The detector 3 has a motherboard 31 and a battery 33 connected inside. The detector 3 has a probe 32 that is electrically connected to the motherboard 31. The probe 32 can be inserted into the soil to monitor the soil environment.

[0037] Connecting wire 2 is used to electrically connect the probe cone 1 and the detector 3.

[0038] As can be seen from the above, by setting up the probe cone 1, the detector 3 and the connecting line 2 connecting the two, the user can insert the probe cone 1 from the middle of the side of the corn ear. After the cone tube 12 penetrates the coating and is stably inserted into the kernel, the connecting hole 13 connects the cavity between the coating and the kernel of the ear. At this time, the microenvironment sensor 120 is connected to the cavity, and then the cavity is monitored in real time so that the user can obtain accurate data on the growth environment of the corn kernel in real time.

[0039] The reinforcement assembly includes a knob 14 rotatably connected to the outer casing 11, a lead screw 15 fixedly connected to the knob 14, and a slider 16 threadedly connected to the lead screw 15. The end of the lead screw 15 is rotatably connected to the inner wall of the tapered tube 12. A side groove 17 is provided on the side wall of the tapered tube 12. A limiting rod 18 is connected to the inner wall of the side groove 17. A rotating plate 19 is provided inside the side groove 17. A long groove for accommodating the limiting rod 18 is provided on the rotating plate 19. The upper end of the rotating plate 19 is hinged to the slider 16.

[0040] As can be seen from the above, after the user inserts the conical tube 12 into the corn cob, the knob 14 can be rotated to drive the lead screw 15 to rotate. The rotating lead screw 15 drives the slider 16 to slide inside the conical tube 12. The sliding slider 16 will drive one end of the rotating plate 19 to move, thereby causing the rotating plate 19 to rotate around the limiting rod 18. The rotating plate 19 will be inserted into the corn cob, enhancing the connection stability between the conical tube 12 and the corn cob.

[0041] To facilitate the insertion of the rotating plate 19 into the corn cob, the lower end of the rotating plate 19 is set with a pointed tip.

[0042] The motherboard 31 is equipped with a control chip, a soil moisture sensor, and a wireless communication module. The motherboard 31 is electrically connected to the probe 32. The data collected by the microenvironment sensor 120 can be transmitted to the motherboard 31 via the connection line 2. The motherboard 31 transmits this information and soil monitoring data together to the target personnel through wireless transmission.

[0043] The outer shell 11 has a larger diameter than the conical tube 12. When the conical tube 12 is inserted into the corn cob, the outer shell 11 can block the insertion opening to prevent insects or other substances from entering and contaminating the fruit.

[0044] The outer shell 11 is connected to a surrounding membrane 121 near the tapered tube 12. The surrounding membrane 121 is a rubber ring membrane, which makes the surrounding membrane 121 deformable and convenient for the surrounding membrane 121 to wrap around the insertion port of the tapered tube 12.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
