Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, and in particular to a pesticide spraying device for aircraft. Background Technology

[0002] In the process of agricultural modernization, agricultural aviation technology has been continuously innovated and widely applied. Aircraft, with their advantages of high efficiency and ability to cover large areas of farmland, have become powerful tools for pesticide spraying operations. To meet the stringent requirements of agricultural production for precise and efficient pesticide application, pesticide spraying devices are a key component of aircraft.

[0003] Currently, in pesticide spraying systems mounted on aircraft, the pesticide storage tank is closely connected to monitoring equipment such as level detectors. When the pesticide in the storage tank is depleted, operators face two options: either refill the storage tank directly on the aircraft, or replace the storage tank. If replacement is chosen, the monitoring equipment is firmly fixed to the tank, meaning the first step in disassembling the tank is to remove the monitoring equipment. Even though some storage tanks use quick-release connectors or interfaces to connect to level gauges and other equipment, allowing for easy separation and installation of these devices from the old tank, the process remains cumbersome. Each tank replacement requires repeated disassembly and reassembly, significantly increasing the installation time. Even more challenging is that when it is necessary to change to a storage tank of different depths, the equipment may need to be adjusted to ensure that level gauges and other equipment can accurately measure the liquid level. This undoubtedly slows down the operation process, brings many inconveniences to the busy actual pesticide spraying work, and seriously affects the efficiency of the operation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pesticide spraying device for aircraft, so as to solve the technical problems mentioned in the background art.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A pesticide spraying device for an aircraft, comprising: an aircraft body and a mounting plate, wherein the aircraft body and the mounting plate are detachably connected; a pesticide storage tank, detachably mounted on the aircraft body; a transition box, disposed on the mounting plate and located on the side of the mounting plate facing the pesticide storage tank, the transition box providing a position for a level gauge; a mounting groove, formed on the side of the transition box facing the pesticide storage tank, the mounting groove being adapted to the pesticide storage tank; and a connecting block, disposed on the side of the pesticide storage tank facing the transition box. On one side of the box, the connecting block is used to connect the medicine storage box and the transition box. The connecting block has a slot. The locking block is slidably connected to the transition box. The locking block is adapted to the slot and is used to fix the position of the connecting block. The transition box is set on the side of the mounting plate facing the medicine storage box. It is specially designed to provide an installation position for monitoring equipment such as level gauges, so that the monitoring equipment can be separated from the medicine storage box. When replacing the medicine storage box, it is not necessary to disassemble the monitoring equipment. The detachable connection between the aircraft body and the mounting plate should be easy to operate and firm and reliable, and will not loosen during flight.

[0006] In a further embodiment, multiple ejector springs are provided. The ejector springs are located on the side of the locking block away from the medicine storage tank. The ejector springs are installed inside the transition box. The ejector springs are used to push the locking block to move towards the connecting block. The elastic performance of the ejector springs should meet the requirement of normal operation under various environmental conditions and should not fail due to changes in temperature and humidity. The installation position of the springs should be precise to ensure that the force pushing the locking block is uniform.

[0007] In a further embodiment, a fixing rod is connected to a locking block at one end and passes through a transition box at the other end; a fixing key is installed on the transition box, and the fixing key is used to limit the position of the fixing rod. The materials of the fixing rod and the fixing key should have sufficient strength and wear resistance. The fixing key should limit the fixing rod in a way that is easy to operate and will not loosen on its own under flight vibration.

[0008] In another embodiment, a drug outlet is provided on the drug storage box, and the drug outlet is located on the side of the drug storage box facing the transition box; a drug inlet is provided on the transition box, and the drug inlet is located on the side of the transition box facing the drug storage box. The inner diameter of the drug inlet is adapted to the outer diameter of the drug outlet. The shape and size accuracy of the drug outlet and the drug inlet should be high. A sealing ring can also be added inside the drug inlet to ensure the sealing performance during docking and prevent drug leakage. The position design of the drug outlet and the drug inlet should facilitate the connection operation between the drug storage box and the transition box.

[0009] In a further embodiment, a sealing block is slidably installed inside the drug outlet, the sealing block being adapted to the drug outlet and used to seal the drug outlet; a push rod is stably installed inside the drug inlet, the push rod being used to push the sealing block to open the drug outlet, wherein the sealing block has good sealing performance and can effectively prevent drug leakage; the length and position of the push rod are designed reasonably to ensure that the sealing block can be accurately pushed during docking without damaging the sealing block.

[0010] In a further embodiment, a limiting rod is slidably installed inside the medicine outlet. One end of the limiting rod is connected to the sealing block. The limiting rod is used to limit the movement trajectory of the sealing block. The material of the limiting rod should have a certain rigidity to prevent deformation during the movement of the sealing block. The fit between the limiting rod and the medicine outlet should be smooth and should not affect the normal movement of the sealing block.

[0011] In a further embodiment, a return spring is stably installed inside the drug outlet. The return spring is located outside the limiting rod and is used to reset the sealing block so that the sealing block seals the drug outlet. The spring has a suitable elastic coefficient to ensure that the sealing block resets quickly without damaging the sealing block and related components. The spring also has good durability and can withstand multiple expansion and contraction cycles.

[0012] In a further embodiment, the height of the drug outlet facing the transition box is at most equal to the height of the connecting rod. The relationship between the height of the drug outlet and the height of the connecting rod should be strictly controlled during the design and manufacturing process, and the error should be controlled within a very small range.

[0013] In a further embodiment, the internal cross-section of the drug outlet is stepped, with its maximum diameter being larger than the diameter of the sealing block and its minimum diameter being smaller than the diameter of the sealing block. The dimensional accuracy of the diameters of each part of the stepped drug outlet must be high, and the transition between different diameter parts must be smooth so as not to affect the movement of the sealing block.

[0014] In a further embodiment, the cross-section of the portion of the card block that enters the mounting groove is semi-circular, wherein the size of the semi-circular portion is adapted to the card groove, and the surface is smooth to reduce frictional resistance and improve the service life of the card block.

[0015] Beneficial effects: 1. By setting the transition box on the mounting plate and providing a liquid level gauge installation position, and by making the aircraft body and the mounting plate, as well as the medicine tank and the aircraft body, detachably connected, and by connecting blocks, slots, and the transition box's locking blocks, ejection springs, and fixing keys, the liquid level gauge and other monitoring equipment can be installed separately from the medicine tank. This eliminates the need to disassemble the monitoring equipment when replacing the medicine tank, thus simplifying the medicine tank replacement process, significantly shortening the medicine tank installation time, and improving operational efficiency.

[0016] 2. By utilizing the interlocking structure of the pesticide outlet on the storage tank, the pesticide inlet on the transition tank, and the sealing block, limiting rod, return spring inside the outlet, and the top rod inside the inlet, the pesticide outlet is opened and the pesticide is delivered when the storage tank and the transition tank are connected, and the outlet is sealed when they are separated. This achieves precise control of pesticide delivery, avoids pesticide leakage, and ensures the smooth operation of pesticide spraying. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in this utility model are described clearly and completely. Obviously, the described embodiments are only some, not all, of the embodiments in this utility model. All other embodiments obtained by those skilled in the art based on the embodiments in this utility model without creative effort are within the scope of protection of this utility model.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1-8 A pesticide spraying device for an aircraft includes: an aircraft body 1 and a mounting plate 2, the aircraft body 1 and the mounting plate 2 being detachably connected; a pesticide storage tank 3, detachably mounted on the aircraft body 1; a transition box 4, disposed on the mounting plate 2 and located on the side of the mounting plate 2 facing the pesticide storage tank 3, the transition box 4 providing a liquid level gauge mounting position; a mounting groove 401, formed on the side of the transition box 4 facing the pesticide storage tank 3, the mounting groove 401 being adapted to the pesticide storage tank 3; a connecting block 301, disposed on the side of the pesticide storage tank 3 facing the transition box 4, the connecting block 301 being used to connect the pesticide storage tank 3 and the transition box 4, the connecting block 301 having a slot; and a locking block 5, slidably connected to the transition box 4, the locking block 5 being adapted to the slot, the locking block 5 being used to fix the position of the connecting block 301.

[0030] The device achieves detachable connection between the aircraft body 1 and the mounting plate 2, and between the medicine tank 3 and the aircraft body 1, which facilitates the overall installation, disassembly and maintenance of the device; the transition box 4 provides an independent installation position for the level gauge, and the medicine tank 3 is stably connected to the transition box 4 through the cooperation of the connecting block 301, the slot and the locking block 5.

[0031] Multiple ejector springs 6 are provided. The ejector springs 6 are located on the side of the locking block 5 away from the medicine storage box 3. The ejector springs 6 are installed inside the transition box 4. The ejector springs 6 are used to push the locking block 5 to move towards the connecting block 301.

[0032] The elastic force of multiple ejector springs 6 is used to push the locking block 5 towards the connecting block 301, ensuring that the locking block 5 can be smoothly locked into the slot of the connecting block 301, and securely connecting the medicine storage box 3 and the transition box 4.

[0033] The fixing rod 501 is connected to the locking block 5 at one end and passes through the transition box 4 at the other end; the fixing key 8 is installed on the transition box 4 and is used to limit the position of the fixing rod 501.

[0034] The fixed rod 501 is connected to the card block 5 and passes through the transition box 4. With the help of the fixed key 8 installed on the transition box 4, the position of the fixed rod 501 is limited, preventing the card block 5 from accidentally sliding out of the card slot and enhancing the connection stability.

[0035] The medicine outlet 302 is provided on the medicine storage box 3, and the medicine outlet 302 is located on the side of the medicine storage box 3 facing the transition box 4; the medicine inlet 402 is provided on the transition box 4, and the medicine inlet 402 is located on the side of the transition box 4 facing the medicine storage box 3, and the inner diameter of the medicine inlet 402 is adapted to the outer diameter of the medicine outlet 302.

[0036] This ensures that the drug outlet 302 on the drug storage box 3 and the drug inlet 402 on the transition box 4 can be precisely aligned when they are connected. The inner diameter of the drug inlet 402 is compatible with the outer diameter of the drug outlet 302, ensuring that the drug can flow smoothly from the drug storage box 3 into the transition box 4.

[0037] A sealing block 304 is slidably installed inside the drug outlet 302. The sealing block 304 is adapted to the drug outlet 302 and is used to seal the drug outlet 302. A push rod 403 is stably installed inside the drug inlet 402 and is used to push the sealing block 304 to open the drug outlet 302.

[0038] The sealing block 304 slides within the drug outlet 302 to seal the drug outlet 302 and prevent drug leakage; the push rod 403 inside the drug inlet 402 can push the sealing block 304 to open the drug outlet 302 during docking and control drug delivery.

[0039] A limiting rod 303 is slidably installed inside the medicine outlet 302. One end of the limiting rod 303 is connected to the sealing block 304. The limiting rod 303 is used to limit the movement trajectory of the sealing block 304.

[0040] The limit rod 303 is slidably installed inside the medicine outlet 302 and connected to the sealing block 304, which limits the movement trajectory of the sealing block 304 and ensures that it can accurately open and close the medicine outlet 302.

[0041] The return spring 7 is stably installed inside the medicine outlet 302. The return spring 7 is located outside the limit rod 303. The return spring 7 is used to reset the sealing block 304 so that the sealing block 304 seals the medicine outlet 302.

[0042] When the push rod 403 stops pushing the sealing block 304, the reset spring 7 uses its elastic force to push the sealing block 304 back to its original position, resealing the drug outlet 302 and preventing drug leakage.

[0043] The height of the medicine outlet 302 facing the transition box 4 is at most equal to the height of the connecting rod.

[0044] This ensures that the medicine outlet 302 and the connecting rod will not interfere with each other during the connection process between the medicine storage box 3 and the transition box 4, thus ensuring a smooth connection operation.

[0045] The internal cross-section of the medicine outlet 302 is stepped, with its maximum diameter being larger than that of the sealing block 304 and its minimum diameter being smaller than that of the sealing block 304.

[0046] The internal diameter of the medicine outlet 302 is designed in a stepped shape, which provides space for the installation and movement of the sealing block 304, and at the same time plays a limiting role when the sealing block 304 is reset, ensuring the sealing effect.

[0047] The cross-section of the portion of the card block 5 that enters the mounting groove 401 is semi-circular.

[0048] The design incorporates a semi-circular cross-section for the portion of the card block 5 that enters the mounting slot 401, resulting in a tighter fit between the card block 5 and the slot, a more stable connection, and smoother insertion and removal.

[0049] During use, first, the mounting plate 2 with the transition box 4 is detachably connected to the aircraft body 1, and equipment such as the level gauge is installed in the position provided by the transition box 4. When installing the medicine storage tank 3, the connecting block 301 facing the transition box 4 of the medicine storage tank 3 is aligned with the mounting groove 401 on the transition box 4 and pushed in. Multiple ejection springs 6 push the locking block 5 towards the connecting block 301, so that the locking block 5 can be smoothly locked into the locking groove of the connecting block 301. Then, the fixing rod 501 is used to fix the transition box 4. With the key 8 engaged, the position of the fixing rod 501 is defined, securely connecting the medicine storage tank 3 and the transition tank 4. At this time, the medicine outlet 302 on the medicine storage tank 3 and the medicine inlet 402 on the transition tank 4 are precisely aligned. During the alignment process, the push rod 403 inside the medicine inlet 402 pushes the sealing block 304 inside the medicine outlet 302, overcoming the elastic force of the return spring 7. The sealing block 304 moves along the trajectory defined by the limiting rod 303, opening the medicine outlet 302, and the medicine flows from the medicine storage tank 3 into the transition tank 4. When replacing the medicine storage box 3, first disconnect the fixing key 8 from the connecting rod, then lift the medicine storage box 3 upwards. During the upward movement of the medicine storage box 3, it will gradually squeeze the locking block 5, causing the locking block 5 to move into the transition box 4, thereby disengaging the locking block 5 from the slot and achieving the purpose of removing the medicine storage box 3. During the process of removing the medicine storage box 3, the return spring 7 will gradually push the sealing block 304 to seal the medicine outlet 302. During the entire connection process between the medicine storage box 3 and the transition box 4, since the height of the medicine outlet 302 facing the transition box 4 is at most equal to the height of the connecting rod, interference between the two is avoided. In addition, the internal stepped diameter design of the medicine outlet 302 provides installation and movement space for the sealing block 304 and limits it during reset, ensuring the sealing effect. The semi-circular cross-section design of the part of the locking block 5 entering the installation groove 401 allows the connecting block 301 to squeeze the locking block 5 into the transition box 4, and allows the locking block 5 to fit tightly with the slot, making the connection stable and the insertion and removal smooth.

[0050] The figures shown in the accompanying drawings are illustrative and are intended only to more intuitively demonstrate the key structure and connection relationships of the pesticide spraying device for aircraft according to this invention. In practical applications, the appearance and size of the device can be adjusted and optimized according to specific needs.
