Description

Technical Field

[0001] This relates to the field of locking technology, and in particular to drones with rotatable locking pesticide nozzles. Background Technology

[0002] With the development of modern society, people are paying increasing attention to the quality and safety of agricultural products. Against this backdrop, agricultural plant protection drones have gradually become an indispensable tool in modern agriculture. Firstly, compared to traditional manual spraying, agricultural plant protection drones can ensure precise positioning and coverage, improving operational efficiency. Secondly, agricultural plant protection drones can reduce the impact on the environment and ecology, protecting the sustainable development of the ecological environment. Traditional agricultural production, with its large use of chemical fertilizers and pesticides, causes significant pollution and resource waste. Agricultural plant protection drones, however, can precisely spray pesticides and fertilizers according to actual needs, avoiding overuse and reducing the impact on the ecological environment. Furthermore, agricultural plant protection drones can promote the sustainability of agricultural production and accelerate the modernization of agriculture. Finally, the application of agricultural plant protection drones can expand farmers' production space, increase yields and profits, while reducing labor costs and the input of pesticides and fertilizers, making agricultural production more convenient, economical, and efficient.

[0003] In the current development of drones, agricultural plant protection drones can spray liquid pesticides or nutrient solutions such as insecticides, fungicides, herbicides, ripening and defoliating agents, sugar-enhancing agents, and foliar fertilizers. They can also sow solid seeds and perform field surveying. The application of agricultural plant protection drones plays a vital role in controlling pests and diseases and increasing crop yields. However, the traditional structural design of agricultural plant protection drones is not ideal. For example, the existing pumping device structure is not well-designed, resulting in unstable operation, uneven spray droplets, large size, and heavy weight. Furthermore, the limitations of the spray boom's arrangement relative to the fuselage lead to problems such as missed spraying during pesticide application. Therefore, it is necessary to optimize the relevant structures of agricultural plant protection drones to improve their operational efficiency.

[0004] The patent document with patent number ZL202111350976.8, published on February 1, 2022, provides a pesticide application device carried by a drone. Through the cooperation of a water tank, impeller pump, nozzle and fluid pipeline, the drone plant protection equipment has a larger spraying flow, reduces the load on the drone and improves spraying efficiency.

[0005] However, the structure is limited by the fixed nozzle, which restricts its spraying angle and range, thus preventing it from providing a more widely applicable spraying drone. Summary of the Invention

[0006] To address the technical problem that existing pesticide application drones, due to the fixed structure of their nozzles, only have a fixed spraying angle and spraying range, and cannot provide a more widely applicable pesticide application drone, the technical solution provided by this invention is as follows:

[0007] A rotary locking assembly for a drone spray nozzle, the assembly comprising:

[0008] A fixed base for connecting the drone arm, a movable base for connecting the drone spray nozzle, and a sleeve;

[0009] The fixed seat and the movable seat are hollow, allowing water pipes and electrical circuits to pass through them;

[0010] The fixed base is provided with a connecting end at the end away from the machine arm, and a limiting protrusion is provided on the end side wall of the connecting end;

[0011] The inner wall of the sleeve is provided with positioning protrusions;

[0012] The movable seat has a positioning groove at one end near the machine arm;

[0013] The limiting protrusion and the positioning protrusion fix each other, thus fixing the positional relationship between the sleeve and the connecting end.

[0014] The positioning protrusion is also used to insert into the positioning groove to fix the positional relationship between the fixed seat and the movable seat;

[0015] The sleeve can move toward the machine arm to release the fixed positional relationship.

[0016] Furthermore, in a preferred embodiment, the component further includes a large spring for providing continuous pressure to the sleeve toward the movable seat.

[0017] Furthermore, a preferred embodiment is provided in which multiple limiting protrusions are evenly distributed on the end sidewall of the connecting end.

[0018] Furthermore, a preferred embodiment is provided in which the number and position of the positioning grooves correspond to the limiting protrusions.

[0019] Furthermore, a preferred embodiment is provided in which the positioning protrusion is narrower at one end near the movable seat than at the other end.

[0020] Furthermore, in a preferred embodiment, the component further includes: a rotation limiting module, the module including: a rotation limiting seat for connecting to the fixed seat, a rotation limiting handle for connecting to the movable seat, and a rotation limiting buckle for limiting;

[0021] The rotating limiting seat is a circular structure with its outer wall connected to the fixed seat and a rotating limiting stop provided on its inner wall;

[0022] The rotating limit buckle has a double-layer structure. The upper outer wall is provided with a rotating limit protrusion. The rotating limit buckle rotates inside the rotating limit seat. The rotation angle difference X degrees is limited to 360 degrees by the rotating limit protrusion and the rotating limit stop.

[0023] The lower outer wall of the rotating limit buckle is provided with rotating limit teeth;

[0024] The end of the rotating limit handle is provided with a rotating limit threshold. The rotating limit buckle is coaxial with the rotating limit handle and rotates at the end of the rotating limit handle. Through the cooperation of the rotating limit tooth and the rotating limit threshold, the rotation angle is limited to X degrees.

[0025] Furthermore, a preferred embodiment is provided in which there are two rotating limit thresholds, which are disposed opposite to each other at the ends of the rotating limit handle.

[0026] Based on the same inventive concept, the present invention also provides a drone spray nozzle, wherein the fixed end and the movable end of the nozzle are connected by the drone spray nozzle rotation locking assembly.

[0027] Based on the same inventive concept, the present invention also provides a drone arm, the arm including the aforementioned nozzle.

[0028] Based on the same inventive concept, the present invention also provides a drone, which includes the aforementioned arm.

[0029] Compared with the prior art, the advantages of the technical solution provided by the present invention are as follows:

[0030] The drone spray nozzle provided by this invention, based on the existing technology, realizes a rotatable nozzle structure through a telescopic rotating sleeve. In different application scenarios, the angle of the nozzle can be adjusted and the distance between the nozzles can be changed as needed, making it more applicable.

[0031] The drone spray nozzle provided by this invention, due to its adjustable nozzle design, allows for functional switching without changing different models of spraying components in operations requiring high spray concentrations, simply by adjusting the angle, thus bringing the nozzles closer together.

[0032] The drone spray nozzle provided by this invention, through the combination of a spring-loaded cone and a groove, can visualize the angle of displacement through sound and touch, increasing the positioning capability of the gear and improving the user experience.

[0033] The drone spray nozzle provided by this invention, through a limiting function, avoids damage to the internal wiring and pipelines of the nozzle due to excessive rotation of the nozzle structure.

[0034] The drone spray nozzle provided by this invention achieves a wide range of adjustable angles within the positive angle range of 0-360 degrees through a double-layer limiting function. Furthermore, by installing it at the 180-degree position in the positive angle, it achieves bidirectional 180-degree adjustment, thus protecting the internal wiring and pipelines of the nozzle while ensuring a wide range of adjustable angles.

[0035] The drone spray nozzle provided by this invention can be freely adjusted between 0 and 360 degrees, which greatly improves the applicability of drones equipped with this nozzle. It can meet any working needs and conditions simply by changing the nozzle angle, without the need to replace the nozzle, thus improving operation and usage efficiency.

Detailed Implementation

[0046] To make the advantages and benefits of the technical solution provided by the present invention clearer, the technical solution provided by the present invention will now be described in further detail with reference to the accompanying drawings, specifically:

[0047] Implementation Method 1: Combination Figure 1-4 This embodiment describes a rotary locking assembly for a drone spray nozzle, the assembly comprising:

[0048] The fixed seat for connecting the drone arm, the movable seat 4 for connecting the drone spray nozzle, and the sleeve 3;

[0049] The fixed seat and the movable seat 4 are hollow, allowing water pipes and electrical circuits to pass through them;

[0050] The fixed base is provided with a connecting end 11 at the end away from the machine arm, and a limiting protrusion 111 is provided on the end side wall of the connecting end 11;

[0051] The inner wall of the sleeve 3 is provided with a positioning protrusion 31;

[0052] The movable seat 4 is provided with a positioning groove 41 at one end near the machine arm;

[0053] The limiting protrusion 111 and the positioning protrusion 31 fix each other and fix the positional relationship between the sleeve 3 and the connecting end 11.

[0054] The positioning protrusion 31 is also used to be inserted into the positioning groove 41 to fix the positional relationship between the fixed seat and the movable seat 4;

[0055] The sleeve 3 can move toward the machine arm to release the fixed positional relationship.

[0056] Specifically:

[0057] The fit between the fixed seat and the movable seat 4: Both the fixed seat and the movable seat 4 are hollow, used to transmit media through water pipes and electrical circuits. The end of the fixed seat away from the machine arm has a connecting end 11, and a limiting protrusion 111 is provided on the end side wall of the connecting end 11. The end of the movable seat 4 near the machine arm has a positioning groove 41. Through the fit between the connecting end 11 and the positioning groove 41, a positional relationship is established between the fixed seat and the movable seat 4.

[0058] The fitting relationship of sleeve 3: Sleeve 3 is a key component connecting the two parts. The inner wall of sleeve 3 is provided with a positioning protrusion 31, while the connecting end 11 of the fixed seat is provided with a limiting protrusion 111. These two protrusions cooperate with each other to fix the positional relationship between sleeve 3 and connecting end 11.

[0059] The positioning protrusion 31 and the positioning groove 41 are fitted together: To ensure the positional relationship between the fixed seat and the movable seat 4, the positioning protrusion 31 is also used to insert into the positioning groove 41. This fit further fixes the positional relationship between the fixed seat and the movable seat 4.

[0060] The movable capability of sleeve 3: Sleeve 3 has the ability to move towards the machine arm. This means that the positional relationship between the fixed seat and the movable seat 4 can be released by moving sleeve 3. In this way, the connection position can be adjusted or the connection can be released.

[0061] In summary, the mating relationship between the fixed seat, the movable seat 4, and the sleeve 3 is achieved through the limiting protrusion 111, the positioning protrusion 31, the positioning groove 41, and the mobility of the sleeve 3. These mating relationships ensure a reliable connection and allow for flexible adjustment of the connection angle.

[0062] Among them, combined Figure 5 In this embodiment, a gear shift pin 32 is also provided inside the fixed base, and a slide 43 and a gear shift groove 44 are also provided at the end of the movable base 4. The gear shift pin 32 is connected to the fixed base by a spring. The spring provides pressure to the gear shift pin 32 toward the gear shift groove 44. When moving, the gear shift pin 32 slides into the slide 43, and when fixed, it slides into the gear shift groove 44 to provide a gear shift feel. The gear shift is matched with the position of the positioning groove 41 and the positioning protrusion 31, which realizes the advantage of quickly and directly inserting the positioning protrusion 31 into the positioning groove 41 without the need for additional rotation to find the matching position of the positioning protrusion 31 and the positioning groove 41.

[0063] Specifically:

[0064] The positioning protrusion 31 and the positioning groove 41 are engaged: As previously described, the positioning protrusion 31 is used to determine the positional relationship between the fixed seat and the movable seat 4, and is inserted into the positioning groove 41 to ensure that their relative positions are stable.

[0065] The engagement of the gear shift pin 32 with the slide rail 43: The slide rail 43 is located at the end of the movable seat 4, and the gear shift pin 32 moves through the slide rail 43. This engagement allows the gear shift pin 32 to slide into the slide rail 43 during movement, thereby achieving gear position adjustment.

[0066] The engagement of the gear shift pin 32 with the gear shift groove 44: When the gear shift pin 32 needs to be fixed, it slides into the gear shift groove 44. This engagement provides additional stability, ensuring that the positions of the fixed seat and the movable seat 4 are fixed.

[0067] In summary, these mating relationships form a stable connection system between the fixed seat, the movable seat 4, the positioning groove 41, and the positioning protrusion 31, while also providing the advantages of quick positioning and adjustment.

[0068] The advantages of the gear shift pin 32 are as follows:

[0069] Gear position feel: The gear position pin 32 is connected to the fixed base via a spring and slides into the slide rail 43 when moving and into the gear position groove 44 when stationary. This design allows the operator to feel the presence and position of the gear during use, thus facilitating accurate selection of the required gear. Gear position feel helps the operator to more precisely control and adjust the operating status of the system or equipment.

[0070] Quick Positioning: Since the gear shift pin 32 slides directly into the slide rail 43 or gear shift slot 44, the operator can adjust the gear position through simple moving or fixing operations. Compared with other methods, such as rotating or adjusting more complex mechanisms to find the accurate mating position, the design of the gear shift pin 32 makes the positioning and adjustment process simpler, more convenient and faster.

[0071] Stability: The gear shift pin 32 is connected to the fixed base by a spring and is held in place by the pressure provided by the spring, moving towards the gear shift groove 44. This design ensures the stability of the gear shift pin 32 during movement and fixation. The mating relationship between the gear shift pin 32 and the slide 43 and gear shift groove 44 also provides additional stability, preventing the gear shift pin 32 from accidentally disengaging or losing its fixation.

[0072] In summary, the gear shift pin 32 in this embodiment offers advantages such as tactile feedback, quick positioning, and stability. These advantages enable the operator to accurately select the gear position and quickly adjust it through simple moving or fixing operations. The design of the gear shift pin 32 simplifies the operation process, improves work efficiency, and provides reliable stability.

[0073] Implementation Method 2: This implementation method is a further limitation of the UAV spray nozzle rotation locking assembly provided in Implementation Method 1. The assembly further includes a large spring 2, which is used to provide continuous pressure to the sleeve 3 toward the movable seat 4.

[0074] Implementation Method 3: This implementation method is a further limitation of the UAV spray nozzle rotation locking assembly provided in Implementation Method 1. There are multiple limiting protrusions 111, which are evenly distributed on the end sidewall of the connecting end 11.

[0075] Implementation Method 4: This implementation method is a further limitation of the UAV spray nozzle rotation locking assembly provided in Implementation Method 3. The number and position of the positioning grooves 41 correspond to the limiting protrusions 111.

[0076] Implementation Method 5: This implementation method is a further limitation of the UAV spray nozzle rotation locking assembly provided in Implementation Method 3, wherein the positioning protrusion 31 is narrower at one end near the movable seat 4 than at the other end.

[0077] Implementation Method Six: Combination Figure 5-8 This embodiment further defines the rotating locking assembly for the drone spray nozzle provided in Embodiment 1. The assembly further includes a rotation limiting module, which includes a rotation limiting seat 51 for connecting to the fixed seat, a rotation limiting handle 53 for connecting to the movable seat 4, and a rotation limiting buckle 52 for limiting.

[0078] The rotating limiting seat 51 has a circular structure, with its outer wall connected to the fixed seat and a rotating limiting stop 511 provided on its inner wall;

[0079] The rotating limit buckle 52 has a double-layer structure. The upper outer wall is provided with a rotating limit protrusion 521. The rotating limit buckle 52 rotates inside the rotating limit seat 51. The rotation angle difference X degrees is limited by the rotating limit protrusion 521 and the rotating limit stop 511 to reach 360 degrees.

[0080] The lower outer wall of the rotating limit buckle 52 is provided with a rotating limit tooth 522;

[0081] The end of the rotating limit handle 53 is provided with a rotating limit threshold 531. The rotating limit buckle 52 is coaxial with the rotating limit handle 53 and rotates at the end of the rotating limit handle 53. Through the cooperation of the rotating limit tooth 522 and the rotating limit threshold 531, the rotation angle is limited to X degrees.

[0082] Figure 6 The diagram shown is a cross-sectional view of the CC line, where the inner and outer rings are: the inner ring is the rotation limit buckle 52, and the outer ring is the rotation limit seat 51.

[0083] Figure 7 The diagram shown is a cross-sectional view of the BB line, where the inner and outer rings are: the inner ring is the rotation limit buckle 52, and the outer ring is the rotation limit handle 53.

[0084] The limit switch 53 is fixedly connected to the inside of the movable seat 4 through the fixing hole 532 and screw 42.

[0085] Specifically:

[0086] The engagement between the rotating limit seat 51 and the fixed seat: The rotating limit seat 51 is a ring structure, and its outer wall is connected to the fixed seat. A rotating limit stop 511 is provided on the inner wall of the rotating limit seat 51. This design allows the rotating limit seat 51 to be tightly connected to the fixed seat and remain stable. The rotation of the rotating limit seat 51 is supported and restricted by the fixed seat, thereby achieving the limitation of the rotation angle.

[0087] The engagement of the rotating limit buckle 52 and the rotating limit seat 51: The rotating limit buckle 52 is a double-layer structure, with a rotating limit protrusion 521 on the upper outer wall. The rotating limit buckle 52 is located inside the rotating limit seat 51 and can rotate within it. Through the engagement of the rotating limit protrusion 521 and the rotating limit stop 511, the rotation angle difference of the rotating limit buckle 52 can be limited to X degrees, thus achieving 360-degree rotational limitation. This design allows the nozzle to rotate 360 ​​degrees without exceeding 360 degrees, achieving the maximum rotation angle while ensuring the safety of the internal pipeline. The rotating limit buckle 52 can rotate within the rotating limit seat 51 and maintain a stable position.

[0088] The engagement of the rotating stop 52 and the rotating stop handle 53: The lower outer wall of the rotating stop 52 is provided with a rotating stop tooth 522. The end of the rotating stop handle 53 is provided with a rotating stop sill 531. The rotating stop 52 and the rotating stop handle 53 are coaxial, and the rotation angle of the rotating stop handle 53 is limited to X degrees by the engagement of the rotating stop tooth 522 and the rotating stop sill 531. This design allows the rotating stop handle 53 to connect with the rotating stop 52 and rotate, while limiting the range of rotation angle.

[0089] In summary, the components in the rotary limiting module have a close fit. The rotary limiting seat 51 is connected to the fixed seat, and the rotary limiting buckle 52 is located inside the rotary limiting seat 51, achieving rotational limiting through the rotary limiting protrusion 521 and the rotary limiting stop 511. The rotary limiting buckle 52 is coaxial with the rotary limiting handle 53, and the rotation angle is limited by the cooperation of the rotary limiting tooth 522 and the rotary limiting threshold 531. These fits ensure the stable operation of the rotary limiting module and accurate angle control.

[0090] Implementation Method Seven: This implementation method is a further limitation of the UAV spray nozzle rotation locking assembly provided in Implementation Method Six. There are two rotation limit thresholds 531, which are arranged opposite to each other at the ends of the rotation limit handle 53.

[0091] Similarly, in this embodiment, there are two rotating limiting teeth 522, which are arranged opposite to each other on the lower sides of the rotating limiting buckle 52.

[0092] Implementation Method 8: This implementation method provides a drone spray nozzle, wherein the fixed end 1 and the movable end of the nozzle are connected by the drone spray nozzle rotation locking assembly provided in Implementation Method 1.
