Description

Technical Field

[0001] This invention relates to the field of foliar fertilization devices, specifically to an improved foliar fertilization device for soybean field planting. Background Technology

[0002] Soybeans are commonly used to make various soy products, extract soybean oil, brew soy sauce, and extract protein, making them a highly regarded source of protein by nutritionists. Therefore, the market demand for soybeans has been substantial in recent years, and their planting area has been expanding, gradually forming a large-scale industry. Because soybeans are a fertilizer-loving crop, their demand for nitrogen and phosphorus fertilizers increases rapidly in the later stages of plant growth, especially during the flowering and grain-filling stages. Relying solely on photosynthesis through leaves and root nutrition is insufficient to meet these needs, often leading to flower and pod drop, and even premature aging, thus affecting soybean yield. Soybean leaves have a strong capacity for nutrient absorption; foliar fertilization allows nutrients to be quickly absorbed by the leaves, meeting the plant's growth needs. Foliar fertilization can also delay leaf senescence and promote plant growth, making it a low-cost, time-saving, labor-saving, and significantly yield-increasing effective measure. Areas for improvement in the use of fertilization equipment include: When using the fertilization device, under normal circumstances, the mixed pesticide solution is loaded into the storage cylinder. The cylinder is then stably fixed below the drone using clamps and connecting plates. The pesticide delivery component and spraying component work together to spray the pesticide solution from the storage cylinder onto the soybean leaves. Warning lights then signal the operator to apply the pesticide, improving fertilization efficiency to some extent. While the spraying component is applying fertilizer to the soybean leaves, the drone maintains a constant altitude to spray the leaves. Because soybeans grow at varying heights, the spraying... The spraying unit, controlled by the drone, maintains a single altitude for spraying pesticides and fertilizers. When spraying fertilizer onto the higher soybean leaves, the distance between the spraying unit and the plant is too small, preventing the spraying unit from effectively and evenly distributing the pesticide. Conversely, when spraying fertilizer onto the lower soybean leaves, the distance between the spraying unit and the plant is too large, preventing the spraying unit from accurately spraying the pesticide onto the soybean leaves. As a result, operators need to observe the drone's fertilization process in real time and adjust the drone's position according to the height of the soybean plants. This not only increases the workload of the operators but also affects the spraying effect on the leaves. Summary of the Invention

Beneficial effects

[0014] This invention discloses an improved foliar fertilization device for soybean field cultivation, which has the following beneficial effects: This invention utilizes a spray assembly, a chuck, clamps, a pesticide storage assembly, and a movable rod. The pesticide storage assembly is installed at the lower end of the machine body, and the two are fixed together by clamps, allowing the pesticide storage assembly to be more stably fixed at the bottom of the machine body.

Implementation

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0025] Please see Figures 1-5 The present invention provides a technical solution: an improved foliar fertilization device for soybean field planting, the structure of which includes a spraying device 1, support legs 2, wings 5, warning lights 3, and body 4. The spraying device 1 is installed at the lower end of the body 4. Support legs 2 and wings 5 ​​are installed around the body 4. A warning light 3 is provided on the top of the body 4 and the two are electrically connected.

[0026] The spraying device 1 includes a spraying assembly Q1, a chuck E3, a clamp W2, a medicine storage assembly R4, and a movable rod T5. The spraying assembly Q1 is located at the lower end of the medicine storage assembly R4 and the two are connected. Movable rods T5 are inserted into both sides of the top of the spraying assembly Q1. The end of the movable rod T5 away from the spraying assembly Q1 is inserted into the lower end of the chuck E3. The chuck E3 is installed on the upper half of the medicine storage assembly R4. The top of the medicine storage assembly R4 is provided with a clamp W2 that engages with it. The medicine storage assembly R4 is installed at the lower end of the machine body 4 through the clamp W2.

[0027] The aforementioned clamp W2 is used to cooperate with the medicine storage component R4 to install the medicine storage component R4 at the lower end of the body 4. The two are fixed together by the clamp W2, so that the medicine storage component R4 can be more stably fixed at the bottom of the body 4. At the same time, it is easy for people to remove the medicine storage component R4 from the body 4 so that people can replenish the medicine inside the medicine storage cylinder in a timely manner.

[0028] The drug storage assembly R4 includes an infusion tube R11, a sensor I15, a solenoid valve T12, a drug storage cylinder U14, a level gauge Y13, and a drug guide connector P16. Two infusion tubes R11 are provided and are connected through each other to the lower ends of the drug guide connector P16. Solenoid valves T12 are connected to both infusion tubes R11. A sensor I15 is installed at the lower end of the drug guide connector P16. The top of the drug guide connector P16 is connected through to the lower end of the drug storage cylinder U14, and the two are in communication. A level gauge Y13 is located at the middle of the front end of the drug storage cylinder U14. A chuck E3 is installed on the lower half of the drug storage cylinder U14. The drug storage cylinder U14 is installed at the lower end of the machine body 4 via a clamp W2. The infusion tube R11 is connected to the spray assembly Q1.

[0029] The liquid level gauge Y13 can detect the liquid in the storage tank in real time and transmit the detected data to the processor inside the body 4. The processor determines the time to add pesticide to the storage tank and uses the warning light 3 to transmit the pesticide addition signal to people, thereby improving the efficiency of spraying pesticides using drones.

[0030] The drug delivery connector P16 includes an interconnecting component D21, a flow cavity F23, an adjusting plate G22, and a stacked guide H24. The interconnecting component D21 is located at the lower end of the stacked guide H24. Multiple adjusting plates G22 are connected through the stacked guide H24 and are arranged in parallel on the stacked guide H24. The stacked guide H24 has a flow cavity F23 inside, which is connected to the interconnecting component D21. Infusion tubes R11 are connected through both sides of the interconnecting component D21. A sensor I15 is installed at the front end of the interconnecting component D21. The stacked guide H24 is connected to the drug storage cylinder U14.

[0031] Multiple adjustment plates G22 of varying sizes are arranged sequentially through overlapping guides H24 to form an inverted cone structure.

[0032] The aforementioned adjusting plate G22 is used to cooperate with the stacked guide H24. The stacked guide H24 is divided into equidistant segments by the adjusting plate G22, so that the stacked guide H24 can be extended and adjusted accordingly under the action of multiple adjusting plates G22.

[0033] The overlapping guide H24 includes a protrusion K31, a non-stick pad Z33, and a telescopic sleeve L32. The protrusion K31 is located on the inner side of the non-stick pad Z33. The outer side of the non-stick pad Z33 is fitted and connected to the inner wall of the telescopic sleeve L32. The upper and lower ends of the telescopic sleeve L32 are connected to adjustment plates G22. The lower end of the telescopic sleeve L32 is provided with an interconnecting part D21. The telescopic sleeve L32 has a flow cavity F23 inside.

[0034] The aforementioned non-stick pad Z33 is used in conjunction with the telescopic sleeve L32. The non-stick pad Z33 fits snugly against the inner wall of the telescopic sleeve L32. The surface of the non-stick pad Z33 is covered with many raised dots K31 with a height of about 5 to 9 micrometers, and each raised dot K31 has many waxy protrusions. When the medicine passes through the telescopic sleeve L32, many raised dots K31 work together with the non-stick pad Z33 to repel the medicine, thereby keeping the inner wall of the telescopic sleeve L32 dry and preventing the medicine from remaining on the inner wall of the telescopic sleeve L32, so that the medicine can be fully utilized.

[0035] The working principle of the above technical solution is explained below: In use, the medicine storage component R4 is installed at the lower end of the machine body 4, and the two are fixed together by clamp W2, which makes the medicine storage component R4 more stably fixed at the bottom of the machine body 4, and at the same time facilitates the removal of the medicine storage component R4 from the machine body 4, so that the medicine can be replenished into the medicine storage cylinder in a timely manner. A chuck E3 is installed on the lower half of the medicine storage component R4. The chuck E3 uses the movable rod T5 to stably install the spray component Q1 at the lower end of the medicine storage component R4. The mixed medicine is injected into the medicine storage cylinder U14, and the medicine storage cylinder U14 is stably installed at the bottom of the machine body 4 by clamp W2. The medicine storage cylinder U14 is connected to the medicine guide connector P16. The overlapping guide H24 on the medicine guide connector P16 is equidistantly spaced by multiple adjusting plates G22. The segmented design allows the overlapping guide H24 to extend and adjust under the action of multiple adjusting plates G22. Telescopic sleeves L32 are installed between each pair of adjusting plates G22. The aircraft 4 sprays fertilizer onto the soybean leaves by flying over the soybean field via its wings 5. During the process of spraying fertilizer onto the soybean leaves, the aircraft 4 maintains the storage cylinder U14 at a certain height. The height of the soybeans is sensed by a sensor I15 installed at the lower end of the storage cylinder U14. Upon receiving the sensor signal, the aircraft 4 adjusts the telescopic sleeves L32 accordingly. The telescopic sleeves L32 extend and retract under the action of the adjusting plates G22 according to the height of the soybeans, causing the adjusting plates G22 to move up and down. An interconnecting component D21 is installed at the lower end of the adjusting plate G22 at the end of the overlapping guide H24. Both sides of the connecting part D21 are connected to infusion pipes R11. The infusion pipes R11, driven by the connecting part D21, move the spray assembly Q1. Under the action of the movable rod T5, the spray assembly Q1 moves up and down on the chuck E3 to adjust to the position corresponding to the soybean. Under the action of the movable rod T5 and the overlapping guide H24, the spray assembly Q1 stably follows the height of the soybean, ensuring that the distance between the spray assembly Q1 and the soybean leaves remains the same, effectively and evenly spraying the pesticide solution and ensuring the accuracy of the spray. The pesticide solution inside the storage cylinder U14 is then transferred downwards to the flow chamber F23 inside the overlapping guide H24. The inner wall of the telescopic sleeve L32 on the overlapping guide H24 is fitted with a non-stick pad Z3. 3. The surface of the non-stick pad Z33 is covered with numerous raised dots K31, each approximately 5-9 micrometers high, and each K31 has many waxy protrusions. When the pesticide solution passes through the telescopic sleeve L32, the numerous raised dots K31, in conjunction with the non-stick pad Z33, repel the pesticide solution, thus keeping the inner wall of the telescopic sleeve L32 dry. This prevents the pesticide solution from accumulating on the inner wall of the telescopic sleeve L32, allowing the pesticide solution to be effectively dispersed and conducted through the interconnecting component D21 to the infusion pipe R11. From there, the pesticide solution is injected into the spraying assembly Q1 for fertilization of the soybean leaves. Simultaneously, the level gauge Y13 on the pesticide storage cylinder U14 can monitor the pesticide solution level inside in real time and transmit the detected data to the processor inside the machine body 4.The processor determines the timing of pesticide application from the storage tank and uses warning light 3 to signal the application, thus improving the efficiency of pesticide spraying using the machine body 4. Example

[0036] Please see Figures 6-7 This invention provides a technical solution: an improved foliar fertilization device for soybean field planting. The spraying component Q1 includes a connecting plate C41, a connector V43, a spraying screw N42, and an insertion hole M44. The upper end of the connecting plate C41 is provided with four insertion holes M44. The inner walls of the connecting plate C41 are provided with connectors V43 that communicate with them. The lower end of the connecting plate C41 is equipped with multiple spraying screws N42. The multiple spraying screws N42 are equidistantly arranged in a ring on the connecting plate C41. The connector V43 is fitted with an infusion tube R11. A movable rod T5 is inserted into the insertion hole M44.

[0037] The aforementioned connector V43 is used to mate with the connecting plate C41. The connecting plate C41 is connected to the infusion tube R11 through the connector V43. The infusion tube R11 will then transmit the mixed medicine inside the medicine storage cylinder U14 to the inside of the connecting plate C41 through the connector V43. The medicine inside the connecting plate C41 will then disperse and flow into each spraying nozzle N42.

[0038] The spraying rotor N42 includes a rotating disk E51, a snap-fit ​​component Y54, a funnel I56, a rotating shaft T52, a connecting piece P57, a conical segment U55, and rotating blades R53. The snap-fit ​​component Y54 is located in the middle of the rotating disk E51. The lower end of the conical segment U55 is connected to the middle of the upper end of the rotating disk E51. The end of the conical segment U55 away from the rotating disk E51 is connected to the funnel I56. Three rotating blades R53 are provided on the rotating disk E51. The three rotating blades R53 are located on the rotating disk E51 through the rotating shaft T52. The rotating blades R53 are connected to the snap-fit ​​component Y54 through the rotating disk E51. The funnel I56 is installed at the lower end of the connecting disk C41, and the two are connected.

[0039] The conical section U55 is provided with multiple spray holes that are connected to it.

[0040] The rotating blade R53 has multiple equally spaced contact plates P57 inserted inside, which causes the rotating blade R53 to rotate under the action of the rotating disk E51. The multiple contact plates P57 can work with the rotating blade R53 to disperse and spray the sprayed medicine, effectively expanding its spraying range.

[0041] The working principle of the above technical solution is explained below: In use, the connector C41 has an insertion hole M44 that mates with the movable rod T5, allowing the connector C41 to be mounted on the lower end of the chuck E3 via the movable rod T5. Multiple equidistant, annularly arranged spray nozzles N42 are mounted on the connector C41. The connector C41 is connected to the infusion tube R11 via a connector V43, which then transmits the mixed medicine solution inside the medicine storage cylinder U14 through the connector V43. Inside the connecting plate C41, the liquid medicine inside C41 is dispersed and flows into the funnels I56 in each spraying rotor N42. The cone-shaped section U55 at the lower end of the funnel I56 has numerous spray holes, allowing the liquid medicine entering the funnel I56 to be sprayed outwards through these holes. A rotating disk E51 is installed at the lower end of the funnel I56, and the rotating disk E51 is connected to three rotating blades R53 via a rotating shaft T52. The rotating disk E51, positioned at a distance from the ring, rotates under the action of the snap-fit ​​connector Y54. The three rotating blades R53 above it are pulled outwards by centrifugal force under the action of the rotating shaft T52, thus cooperating with the rotating disk E51 to spray and disperse the pesticide solution sprayed from the spray holes on the conical section U55. Multiple equidistant contact plates P57 are inserted inside the rotating blades R53. As the rotating disk E51 rotates, the contact plates P57 work in conjunction with the rotating blades R53 to disperse the pesticide solution. The pesticide solution is sprayed out through the gaps between the contact plates P57, effectively expanding the spraying range. Through the connecting disk C41, under the action of the movable rod T5 and the pesticide guide connector P16, the pesticide solution can be accurately and efficiently sprayed evenly onto the soybean leaves, thereby improving the fertilization effect of the spray assembly on the soybean leaves and reducing the workload of the operators.

[0042] In summary, this invention employs a combination of a spraying device, outriggers, wings, warning lights, and a body to form a new and improved foliar fertilization device for soybean field cultivation. The pesticide storage component is installed at the lower end of the body, and the two are fixed together by clamps, allowing the pesticide storage component to be more stably fixed below the body. This also facilitates the removal of the pesticide storage component from the body, enabling timely replenishment of pesticide solution into the storage tank. The chuck installed on the pesticide storage component is connected to the spraying component via a movable rod, and the spraying component then connects with the pesticide storage component. The two work together to achieve a spraying effect, effectively spraying pesticide solution onto the soybean leaves.
