Technical Field

[0001] This application relates to the field of spraying technology, and in particular to a turntable assembly, spraying mechanism and mobile platform. Background Technology

[0002] In related technologies, mobile platforms are typically equipped with spraying mechanisms for operation. For example, agricultural plant protection drones use atomizing devices to atomize liquids for spraying during plant protection operations. However, traditional agricultural plant protection drones have complex atomizing disc structures, high maintenance costs, and are prone to problems such as uneven spray particle size and insufficient spray flow rate. Utility Model Content

[0003] The embodiments of this application provide a turntable assembly, a spraying mechanism, and a movable platform to solve at least one of the aforementioned technical problems.

[0004] In a first aspect, an embodiment of this application provides a turntable assembly comprising: a turntable body having an inner circumferential surface and an outer circumferential surface; a feed inlet disposed on the turntable body for introducing material; and multiple discharge outlets disposed at different heights on the outer circumferential surface of the turntable body; wherein the projection of the vertical cross-section of the turntable body is approximately trapezoidal, with one end near the feed inlet corresponding to the short side of the trapezoid and the other end away from the feed inlet corresponding to the long side of the trapezoid; the inner circumferential surface of the turntable body is provided with multiple protruding guide ribs for guiding the material introduced by the feed inlet to the multiple discharge outlets.

[0005] In the turntable assembly designed above, on the one hand, the projection of the vertical cross-section of the turntable body is roughly trapezoidal, with the end near the feed inlet corresponding to the short side of the trapezoid and the other end away from the feed inlet corresponding to the long side of the trapezoid. The shape design of the turntable body is conducive to the smooth flow and dispersion of materials. On the other hand, combined with the guidance of the guide ribs, the material is guided from the feed inlet to multiple discharge outlets at different heights, which is conducive to the height diversion of materials and particle size refinement. The combination of these two aspects takes into account both the spray flow rate requirements and the spray uniformity requirements, and the structure is simple.

[0006] Secondly, an embodiment of this application provides a turntable assembly comprising: a turntable body having an inner circumferential surface and an outer circumferential surface; a feed inlet disposed on the turntable body for introducing material; and a plurality of discharge outlets, including a first set of discharge outlets and a second set of discharge outlets, wherein the first set of discharge outlets is located at a first height on the outer circumferential surface of the turntable body, and the second set of discharge outlets is located at a second height on the outer circumferential surface of the turntable body, the first set of discharge outlets being closer to the feed inlet than the second set of discharge outlets, and the diameter corresponding to the first height being smaller than the diameter corresponding to the second height; wherein the inner circumferential surface of the turntable body is provided with a plurality of protruding guide ribs for guiding the material introduced by the feed inlet to the plurality of discharge outlets.

[0007] In the aforementioned turntable assembly, on the one hand, the diameter of the first set of discharge ports and the second set of discharge ports on the outer circumference of the turntable body is smaller than that of the second set of discharge ports, which is closer to the inlet. This facilitates the smooth flow and dispersion of materials from the inlet to multiple discharge ports. On the other hand, the guide ribs guide the materials from the inlet to multiple discharge ports at different heights, which is beneficial for the height diversion of materials and particle size refinement. The combination of these two aspects takes into account both the spray flow rate requirements and the spray uniformity requirements, and the structure is simple.

[0008] Thirdly, the spraying mechanism provided in this application includes: a power component; and a turntable assembly as described in the first or second aspect above, wherein the turntable assembly rotates under the drive of the power component so that the material is thrown out from the plurality of liquid outlets under the action of centrifugal force.

[0009] Fourthly, an embodiment of this application provides a mobile platform comprising: a platform body; and a spraying mechanism as described in the third aspect; wherein the spraying mechanism is mounted on the platform body.

[0030] The materials used in the embodiments of this application include liquids, solids, or solid-liquid mixtures. For example, liquids include pure liquids or gas-liquid mixtures, such as pesticides, water, and fire-fighting fluids. For ease of description, liquids will be used as the spraying material in the following description, with the inlet described as a liquid inlet, the outlet as a liquid outlet, and the material channel as a liquid flow channel. The same applies to other types of materials.

[0031] The mobile platform in this application embodiment includes, but is not limited to, unmanned vehicles, such as rotary-wing unmanned aerial vehicles and fixed-wing drones. The mobile platform can also be other types of manned vehicles, such as manned aircraft. This application embodiment is not limited to these.

[0032] Firstly, please refer to Figures 1 to 11This application provides a turntable assembly 100 including a turntable body 12, a liquid inlet 14, and multiple liquid outlets 16. The turntable body 12 has an inner peripheral surface 18 and an outer peripheral surface 20. The liquid inlet 14 is located on the turntable body 12 and is used to introduce liquid. The multiple liquid outlets 16 are located at different heights on the outer peripheral surface 20 of the turntable body 12. The projection of the vertical cross-section of the turntable body 12 is approximately trapezoidal, with the end near the liquid inlet 14 corresponding to the short side of the trapezoid and the end away from the liquid inlet 14 corresponding to the long side of the trapezoid. The inner peripheral surface 18 of the turntable body 12 is provided with multiple protruding guide ribs 22, which are used to guide the liquid introduced by the liquid inlet 14 to the multiple liquid outlets 16.

[0033] In the aforementioned turntable assembly 100, on the one hand, the projection of the vertical cross-section of the turntable body 12 is roughly trapezoidal, with the end near the liquid inlet 14 corresponding to the short side of the trapezoid and the other end away from the liquid inlet 14 corresponding to the long side of the trapezoid. The shape design of the turntable body 12 is conducive to the smooth flow and dispersion of the liquid. On the other hand, combined with the guidance of the guide ribs 22, the liquid is guided from the liquid inlet to multiple liquid outlets 16 at different heights, which is conducive to the height division of the liquid and the refinement of the particle size. The combination of the two aspects takes into account both the spray flow rate requirements and the spray uniformity requirements, and the structure is simple.

[0034] Specifically, the turntable assembly 100 can be applied to, but is not limited to, mobile platforms, including but not limited to aircraft and vehicles. Aircraft include, but are not limited to, drones. The turntable assembly 100 can disperse and atomize the introduced liquid and spray the atomized liquid from the outlet 16.

[0035] Optionally, the turntable assembly 100 further includes a rotating shaft 24, a diverter 26, and a fixing member 28. The diverter 26 is disposed on the inner circumferential surface 18 of the turntable body 12 and is fixedly connected to the turntable body 12 by means of bolts 30 or more. The fixing member 28 is disposed on the side of the diverter 26 facing away from the inner circumferential surface 18 of the turntable body 12. The rotating shaft 24 passes through the turntable body 12 and the diverter 26 and is connected to the fixing member 28. The rotating shaft 24 can be connected to a power assembly, which drives the rotating shaft 24 to rotate, thereby driving the diverter 26 and the turntable body 12 to rotate through the fixing member 28, so that the turntable body 12 disperses and atomizes the introduced liquid and sprays it to the outside from the liquid outlet 16. Optionally, in one embodiment, the end of the rotating shaft 24 is a slotted end, which is threadedly connected to the internal threaded hole of the fixing member 28.

[0036] In one embodiment, the drone can be an agricultural drone. The drone can deliver pesticide to the inlet 14 through a pipe and drive the turntable assembly 100 to rotate via the rotating shaft 24, thereby dispersing and atomizing the pesticide. When performing agricultural operations, the drone can drive the turntable assembly 100 to rotate, thereby dispersing and atomizing the pesticide and spraying it onto the crops.

[0037] The turntable body 12 is the main component for dispersing and atomizing the liquid. When the turntable assembly 100 is working, the turntable body 12 can rotate at high speed driven by the power component. Due to the centrifugal force of the turntable body 12 during rotation, the introduced liquid will collide with the guide ribs 22. After colliding with the guide ribs 22, the liquid is dispersed outward along the guide ribs 22, and finally atomized and sprayed outward from the liquid outlet 16. The turntable body 12 uses centrifugal force to throw the liquid out to ensure the atomization effect when the liquid is thrown out.

[0038] The inlet 14 is used to introduce liquids, such as medicine. Optionally, in Figure 3 In the rotating platform, the inlet 14 is located at the top of the main body of the rotating platform. The pump of the movable platform can be connected to the inlet 14 and the storage tank through a pipeline. During spraying operations, the pump is started to transport liquid from the storage tank through the pipeline to the inlet 14, thereby introducing the liquid into the main body of the rotating platform 12.

[0039] The liquid outlet 16 is located on the outer peripheral surface 20 of the turntable body 12. The liquid outlet 16 can discharge the atomized liquid from the turntable body 12, thereby enabling external spraying. Multiple liquid outlets 16 are located at different heights on the outer peripheral surface 20 of the turntable body 12, so that multiple liquid outlets 16 can be arranged along the height direction of the turntable body 12, thereby forming multiple liquid layers at different heights.

[0040] The projection of the vertical cross-section of the turntable body 12 is roughly trapezoidal, with the end closer to the liquid inlet 14 corresponding to the short side of the trapezoid and the end farther from the liquid inlet 14 corresponding to the long side of the trapezoid. Therefore, when liquid flows from one end of the liquid inlet 14 to the other end farther from the liquid inlet 14, due to the centrifugal force of the turntable body 12 rotating, the liquid will disperse and flow towards the other end farther from the liquid inlet 14, which is conducive to the rapid flow of the liquid.

[0041] Furthermore, the radii of the rotating disk body 12 corresponding to the liquid outlets 16 at different heights are different, thus the centrifugal force exerted on the liquid by the rotating disk body 12 during rotation is also different. The lower the height of the liquid outlet 16, the larger the radius of the corresponding rotating disk body 12, the greater the centrifugal force exerted on the liquid by the rotating disk body 12 during rotation, and the finer the corresponding atomized particles; conversely, the higher the height of the liquid outlet 16, the smaller the radius of the corresponding rotating disk body 12, the smaller the centrifugal force exerted on the liquid by the rotating disk body 12 during rotation, and the coarser the corresponding atomized particles. In summary, having multiple liquid outlets 16 at different heights on the outer circumferential surface 20 of the rotating disk body 12 is beneficial for liquid height distribution and particle size refinement.

[0042] Multiple guide ribs 22 protrude from the inner circumferential surface 18 of the turntable body 12. When liquid flows into the high-speed rotating turntable body 12 from the inlet 14, the liquid can flow along the inner circumferential surface 18 of the turntable body 12 and hit the guide ribs 22, and then disperse outward along the guide ribs 22, and finally atomize and spray outward from the outlet 16.

[0043] This application does not specifically limit the materials of the turntable body 12 and the guide ribs 22. The material of the turntable body 12 includes, but is not limited to, metal and plastic. The material of the guide ribs 22 includes, but is not limited to, metal and plastic. The materials of the turntable body 12 and the guide ribs 22 can be the same or different. Optionally, in one embodiment, the guide ribs 22 and the turntable body 12 are integrally formed, thereby increasing the connection strength between the turntable body 12 and the guide ribs 22, avoiding gaps that would occur when the turntable body 12 and the guide ribs 22 are connected separately, and thus improving the atomization effect.

[0044] In some implementations, please refer to Figure 9 The guide ribs 22 are distributed in the same clockwise direction from one end of the turntable body 12 near the liquid inlet 14 to the other end of the turntable body 12 away from the liquid inlet 14, around the central axis of the turntable body 12.

[0045] This allows for a larger spraying area and better atomization.

[0046] Specifically, the guide ribs 22 are distributed in a clockwise direction around the central axis of the turntable body 12, from one end of the turntable body 12 near the liquid inlet 14 to the other end of the turntable body 12 away from the liquid inlet 14. On the one hand, the guide ribs 22 can extend from one end of the turntable body 12 near the liquid inlet 14 to the other end of the turntable body 12 away from the liquid inlet 14, making the guide ribs 22 relatively long, which can basically cover the inner circumferential surface 18 of the turntable body 12. Therefore, when the liquid flows along the inner circumferential surface 18 of the turntable body 12, it can have more impacts with the guide ribs 22, thereby improving the atomization effect.

[0047] On the other hand, the guide ribs 22 are distributed in the same clockwise direction around the central axis of the turntable body 12, so that all the guide ribs 22 guide the liquid to the outlet 16 in a substantially the same direction, resulting in a larger spraying range. The liquid sprayed out of the outlet 16 will not collide with each other over a large area, thus reducing the spraying range.

[0048] exist Figure 9 In the illustrated embodiment, the guide ribs 22 are distributed in a clockwise direction around the central axis of the turntable body 12. In other embodiments, the guide ribs 22 are distributed in a counterclockwise direction around the central axis of the turntable body 12. The direction of rotation of the turntable body 12 may be the same as or opposite to the direction of rotation of the guide ribs 22.

[0049] In some implementations, please refer to Figure 9 The angle formed between the guide rib 22 and the inner circumferential surface 18 of the turntable body 12 is an acute angle.

[0050] This can improve the atomization effect.

[0051] Specifically, when the liquid flows along the inner circumferential surface 18 of the turntable body 12, the angle formed between the guide rib 22 and the inner circumferential surface 18 of the turntable body 12 is acute, resulting in a smaller opening between the guide rib 22 and the inner circumferential surface 18 of the turntable body 12. On the one hand, when the liquid flows, the liquid on the inner circumferential surface 18 of the turntable body 12 is less likely to flow out of the turntable body 12 from the bottom of the guide rib 22, thereby increasing the amount of liquid atomization at the liquid outlet 16. On the other hand, the liquid located between the guide rib 22 and the inner circumferential surface 18 of the turntable body 12 has more opportunities to collide with the guide rib 22, thereby improving the refining effect of the liquid outlet 16. In summary, this improves the atomization effect.

[0052] In some examples, the angle formed between the guide rib 22 and the inner circumferential surface 18 of the turntable body 12 is an acute angle T, where T = 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 85 degrees, or other acute angles.

[0053] In some implementations, please refer to Figure 7 and Figure 11 The guide rib 22 includes a first type of guide rib 32 and a second type of guide rib 34 arranged at intervals, and a liquid flow channel 36 is formed between the first type of guide rib 32 and the second type of guide rib 34.

[0054] This allows for the effective guidance of liquids.

[0055] Specifically, the first type of guide ribs 32 and the second type of guide ribs 34 are arranged alternately, forming a liquid flow channel 36 between them. After the liquid flows into the turntable body 12 through the liquid inlet 14, the liquid can enter the liquid flow channel 36. Under the action of centrifugal force when the turntable body 12 rotates, the liquid flow channel 36 guides it to the liquid outlet 16, avoiding or reducing the amount of liquid flowing out from the bottom of the guide ribs 22.

[0056] The height of the guide rib 22 relative to the inner circumference 18 of the turntable body 12 can be designed according to actual needs, and this application does not impose any limitations.

[0057] In some implementations, please refer to Figure 7 , Figure 7a and Figure 11 The first type of guide rib 32 and the second type of guide rib 34 have a height difference at at least some locations.

[0058] Therefore, liquid channels 36 at different heights are formed at locations with height differences, which can divert the liquid in the height direction and increase the atomization amount.

[0059] Specifically, the first type of guide rib 32 and the second type of guide rib 34 have a height difference at at least some locations, and liquid flow channels 36 at different heights are formed at the locations where the height difference exists. When the liquid flows to the location where the height difference exists, the liquid can enter the liquid flow channels 36 at different heights, thereby achieving diversion to different liquid flow channels 36 at different heights, which is applicable to liquids with larger flow rates. For example, when the first type of guide rib 32 and the second type of guide rib 34 have a height difference at all locations, the diverted atomized liquid can be sprayed from the outlet 16 to the outside of the turntable body 12 at different heights, thereby increasing the atomization amount. As another example, when the first type of guide rib 32 and the second type of guide rib 34 have a height difference at some locations, the diverted atomized liquid can merge before reaching the lower layer outlet 16 (such as the last layer outlet 16), and the merged liquid can be sprayed from the lower layer outlet 16 (such as the last layer outlet 16) to the outside of the turntable body 12, thereby increasing the atomization amount.

[0060] In some implementations, please refer to Figure 7a and Figure 11 The first type of guide rib 32 is lower than the second type of guide rib 34 at the end near the liquid inlet 14, and the first type of guide rib 32 is flush with the second type of guide rib 34 at the other end away from the liquid inlet.

[0061] Therefore, the liquid can be diverted near the inlet 14 and the diverted liquid can be merged and converged at a position away from the inlet, so that the turntable body 12 can be adapted to a large liquid inlet volume.

[0062] Specifically, when there is a height difference between the first type of guide rib 32 and the second type of guide rib 34 at some locations, there is a height difference between the first type of guide rib 32 and the second type of guide rib 34 at some locations and no height difference at other locations. In this embodiment, the first type of guide rib 32 is lower than the second type of guide rib 34 at the end near the liquid inlet 14, and the first type of guide rib 32 is flush with the second type of guide rib 34 at the other end away from the liquid inlet, so that there is a height difference between the first type of guide rib 32 and the second type of guide rib 34 at the end near the liquid inlet 14, but no height difference between the first type of guide rib 32 and the second type of guide rib 34 at the other end away from the liquid inlet.

[0063] In some implementations, please refer to Figure 7a Two adjacent second-type guide ribs 34A and 34B, together with the intermediate first-type guide rib 32, form three liquid flow channels 36 at the end near the inlet 14, and two liquid flow channels 36 at the other end away from the inlet 14. Specifically, the liquid flow channel 36B formed by the second-type guide rib 34A and the first-type guide rib 32, the liquid flow channel 36C formed by the second-type guide rib 34B and the first-type guide rib 32, and the liquid flow channel 36A formed between the second-type guide ribs 34A and 34B. For example, when the liquid flow rate is large, the inflowing liquid is split at different heights at the guide ribs near the inlet 14, forming liquid at higher heights and liquid at lower heights. The liquid at higher heights can be preferentially sprayed out from the lower outlet 16 to ensure the liquid spray flow rate, while the liquid at lower heights can fall and be thrown out sequentially along the outlets 16 at different heights. For example, when the liquid flow rate is small, the incoming liquid can fall and be thrown out sequentially along the outlet 16 at different heights to ensure that the liquid is sufficiently abrasive.

[0064] Therefore, the turntable body 12 can be used for large flow rates of liquids.

[0065] Specifically, there is a height difference between the two adjacent second-type guide ribs 34A and 34B and the intermediate first-type guide rib 32 at the end near the liquid inlet 14, so that the two adjacent second-type guide ribs 34A and 34B form a liquid flow channel 36A at the end near the liquid inlet 14, one of the second-type guide ribs 34A and the intermediate first-type guide rib 22 form a liquid flow channel 36B at the end near the liquid inlet 14, and the other second-type guide rib 34B and the intermediate first-type guide rib 22 form a liquid flow channel 36C at the end near the liquid inlet 14, forming a total of three liquid flow channels 36A, 36B and 36C.

[0066] Liquid channels 36B and 36C are located above liquid channel 36A, thus forming layered liquid channels 36 at different heights. Moreover, the three liquid channels 36A, 36B, and 36C can receive a large flow rate of liquid at the liquid inlet 14, making it suitable for large flow rates of liquid and meeting atomization requirements.

[0067] The three liquid channels 36A, 36B, and 36C can merge into two liquid channels 36 at the end away from the liquid inlet 14, thereby increasing the atomization amount and spray range of the spray.

[0068] Furthermore, the liquid flow channel 36A has a larger width, which allows the liquid to flow into the liquid flow channel 36A more quickly, avoiding the problem of insufficient atomization caused by poor liquid inlet.

[0069] In some implementations, please refer to Figure 3 The periphery of the multiple liquid outlets 16 is designed with at least one of the following: a sawtooth shape, a wave shape, and a stepped shape.

[0070] This can improve the atomization effect and increase the spraying range.

[0071] Specifically, the periphery of the outlet 16 is designed with at least one of a toothed shape, a wavy shape, and a stepped shape, such that the periphery of the outlet 16 has edges extending in different directions. For example, with the toothed design, the periphery of the outlet 16 has inclined edges extending in different directions relative to the horizontal direction; with the wavy design, the periphery of the outlet 16 has curved edges that change continuously in different directions relative to the horizontal direction; with the stepped design, the periphery of the outlet 16 has horizontal edges and vertical edges that extend parallel and perpendicular to the horizontal direction.

[0072] When the liquid is sprayed from the outlet 16, it collides with these edges, causing the liquid to be further cut and refined at the periphery of the outlet 16, thus spreading it outwards, thereby improving the atomization effect and increasing the spray range.

[0073] exist Figure 3 In the illustrated embodiment, the periphery of the plurality of liquid outlets 16 is designed in a stepped shape. In other embodiments, the periphery of the plurality of liquid outlets 16 may be any one of a sawtooth shape, a wavy shape, and a stepped shape, or a combination of any two or three of these shapes. The periphery designs of the plurality of liquid outlets 16 may be all identical, partially identical, or partially different.

[0074] In some implementations, please refer to Figure 3 , Figure 4 and Figure 6The multiple liquid outlets 16 include multiple sets of liquid outlets 16, including a first set of liquid outlets 38 and a second set of liquid outlets 40. The first set of liquid outlets 38 is located at a first height on the outer peripheral surface 20 of the turntable body 12, and the second set of liquid outlets 40 is located at a second height on the outer peripheral surface 20 of the turntable body 12. The first height is greater than the second height.

[0075] This allows for the distribution of 16 liquid outlets at different heights, increasing the atomization volume and spraying range.

[0076] Specifically, on the outer peripheral surface 20 of the turntable body 12, the height of the first set of liquid outlets 38 is greater than the height of the second set of liquid outlets 40. Therefore, when liquid is sprayed out from the liquid outlet 16, a spray layer is formed at the first set of liquid outlets 38 and another spray layer is formed at the second set of liquid outlets 40. The turntable body 12 can spray at least two spray layers simultaneously in the height direction, thereby improving the atomization amount and spray range.

[0077] exist Figure 6 In the rotating disc body 12, three sets of liquid outlets 16 are formed on the outer peripheral surface 20, namely K1 group liquid outlet 16, K2 group liquid outlet 16, and K3 group liquid outlet 16 from top to bottom. When the rotating disc body 12 rotates, three spray layers can be formed. The first set of liquid outlets 38 can be at least one of K1 group liquid outlet 16 and K2 group liquid outlet 16, and the second set of liquid outlets 40 can be at least one of K2 group liquid outlet 16 and K3 group liquid outlet 16. Figure 6 In the embodiment shown, the first set of liquid outlets 38 includes K1 set of liquid outlets 16 and K2 set of liquid outlets 16, and the second set of liquid outlets 40 may be K3 set of liquid outlets 16.

[0078] In some implementations, please refer to Figure 6 and Figure 11 The guide rib 22 connects the first set of liquid outlets 38 and the second set of liquid outlets 40 in sequence, until it extends to the far end of the turntable body 12 away from the liquid inlet 14.

[0079] Therefore, the guide rib 22 can direct the incoming liquid to the first set of liquid outlets 38 and the second set of liquid outlets 40, which to a certain extent ensures the amount of liquid at the liquid outlet 16.

[0080] Specifically, the guide rib 22 protrudes from the inner circumferential surface 18 of the turntable body 12. The projection of the vertical cross-section of the turntable body 12 is approximately trapezoidal, with one end near the liquid inlet 14 corresponding to the short side of the trapezoid and the other end away from the liquid inlet corresponding to the long side of the trapezoid. The guide rib 22 extends from top to bottom along the inner circumferential surface 18 of the turntable body 12 from the liquid inlet 14 to the furthest end away from the liquid inlet 14. After the liquid flows into the liquid inlet 14, the guide rib 22 can guide the liquid from the liquid inlet 14 to the first set of liquid outlets 38 and the second set of liquid outlets 40 in sequence, as well as to the furthest end of the turntable body 12 away from the liquid inlet 14, thereby ensuring the liquid output of the first set of liquid outlets 38 and the second set of liquid outlets 40 to a certain extent.

[0081] Optionally, in Figures 1 to 11 In the embodiment shown, the turntable body 12 is provided with a convex and concave structure 42 at the far end away from the liquid inlet 14. The guide rib 22 can also guide the liquid to the convex and concave structure 42. When the turntable body 12 rotates at high speed, the convex and concave structure 42 can further cut and refine the liquid droplets, thereby increasing the atomization amount and spray range.

[0082] In some implementations, please refer to Figure 3 , Figure 6 , Figure 8 and Figure 10 The first set of liquid outlets 38 are evenly spaced around the outer circumference 20, and / or the second set of liquid outlets 40 are evenly spaced around the outer circumference 20 of the turntable body 12.

[0083] This can improve the uniformity of spraying.

[0084] Specifically, the first set of liquid outlets 38 are evenly spaced around the outer circumference 20, so that the atomized liquid sprayed from the first set of liquid outlets 38 is evenly sprayed along the outer circumference 20 of the turntable body 12 at the height of the first set of liquid outlets 38, thereby improving the spray uniformity of the turntable body 12.

[0085] The second set of liquid outlets 40 are evenly spaced around the outer circumference 20 of the turntable body 12, so that the atomized liquid sprayed from the second set of liquid outlets 40 is evenly sprayed along the outer circumference 20 of the turntable body 12 at the height of the second set of liquid outlets 40, thereby improving the spray uniformity of the turntable body 12.

[0086] Please combine Figure 3 , Figure 6 , Figure 8 and Figure 10 In one embodiment, the first set of liquid outlets 38 are evenly spaced around the outer peripheral surface 20, and the second set of liquid outlets 40 are evenly spaced around the outer peripheral surface 20 of the turntable body 12.

[0087] In one embodiment, the first set of liquid outlets 38 are evenly spaced around the outer peripheral surface 20, or the second set of liquid outlets 40 are evenly spaced around the outer peripheral surface 20 of the turntable body 12.

[0088] In some implementations, please refer to Figure 6 The diameter of the first set of outlets 38 is less than or equal to the diameter of the second set of outlets 40, and / or the opening orientation of the first set of outlets 38 is approximately the same as the opening orientation of the second set of outlets 40.

[0089] Therefore, when the liquid flow rate is large, the liquid can preferentially exit from the lower outlet 16.

[0090] Specifically, the diameter of the first set of liquid outlets 38 is less than or equal to the diameter of the second set of liquid outlets 40, and the first height of the first set of liquid outlets 38 on the outer circumferential surface 20 of the turntable body 12 is greater than the second height of the second set of liquid outlets 40 on the outer circumferential surface 20 of the turntable body 12. In other words, the first set of liquid outlets 38 is above the second set of liquid outlets 40. When the liquid flow rate is large, the liquid can preferentially flow out from the lower second set of liquid outlets 40 under the action of gravity and centrifugal force. Since the diameter of the second set of liquid outlets 40 is not less than the diameter of the first set of liquid outlets 38, the lower second set of liquid outlets 40 can accommodate a large flow rate of liquid, ensuring the continuity of atomized liquid output. The first set of discharge outlets 38 is closer to the feed inlet 14 than the second set of discharge outlets 40.

[0091] The opening direction of the first set of liquid outlets 38 is the same as that of the second set of liquid outlets 40, so that the atomized liquid sprayed from the two sets of liquid outlets 16 is sprayed in basically the same direction, ensuring the amount of atomization in the spraying direction, and the atomized liquid sprayed from the two sets of liquid outlets 16 will not collide over a large area, resulting in a small spraying range.

[0092] In some embodiments, the initial velocity of the first set of liquid outlets 38 is less than the initial velocity of the second set of liquid outlets 40.

[0093] As a result, the atomized particles sprayed from the second set of liquid outlets 40 are finer, improving the atomization effect.

[0094] Specifically, please combine Figure 6On the outer circumferential surface 20 of the turntable body 12, the first set of liquid outlets 38 is located above the second set of liquid outlets 40. The projection of the vertical cross-section of the turntable body 12 is roughly trapezoidal, with the end closer to the liquid inlet 14 corresponding to the short side of the trapezoid and the end farther from the liquid inlet corresponding to the long side of the trapezoid. This results in the rotation radius of the turntable body 12 where the first set of liquid outlets 38 is located being smaller than the rotation radius of the turntable body 12 where the second set of liquid outlets 40 is located. According to the centrifugal force F = mω²r, where m is mass, ω is angular velocity, and r is radius, the larger the radius, the greater the initial velocity, and the finer the corresponding atomized particles. In other words, the atomized particles ejected from the second set of liquid outlets 40 are finer than those ejected from the first set of liquid outlets 38, thus improving the atomization effect.

[0095] In some implementations, please refer to Figure 4 , Figure 6 and Figure 10 The main body of the turntable 12 is roughly in the shape of a frustum conical.

[0096] Therefore, the shape of the turntable body 12 is relatively regular, which is conducive to improving the atomization effect and manufacturing efficiency.

[0097] Specifically, a truncated cone can also be called a frustum. The shape of the turntable body 12, which is roughly truncated cone, is relatively regular, avoiding the situation where the sprayed liquid is impacted by the rotating turntable body 12 due to an irregular shape, resulting in a smaller spray range. This is beneficial to improving the atomization effect. Moreover, the regular shape of the turntable body 12 is relatively easy to manufacture, which is beneficial to improving manufacturing efficiency.

[0098] In some implementations, please refer to Figures 1 to 7 The turntable assembly 100 also includes a diverter 26, which is disposed on the turntable body 12 and communicates with the liquid inlet 14 to divert the liquid introduced by the liquid inlet 14.

[0099] This allows the liquid to be introduced into the inlet 14 in an orderly manner, thus ensuring the liquid intake volume.

[0100] Specifically, the diverter 26 is mounted on the turntable body 12 and can rotate synchronously with the turntable body 12. The diverter 26 is connected to the liquid inlet 14. When liquid flows into the liquid inlet 14, the rotating diverter 26 can guide the liquid in an orderly manner to multiple guide ribs 22 on the inner circumferential surface 18 of the turntable body 12, and guide it to the liquid outlet 16. During the liquid flow process, the liquid collides with the guide ribs 22, thereby forming atomized liquid and avoiding blockage of the liquid inlet 14, uneven distribution, slow liquid flow, and uneven atomization.

[0101] The diverter 26 can be fixed to one side of the inner circumferential surface 18 of the turntable body 12 by means of bolts 30 or more. The top of the diverter 26 can divert the liquid introduced by the inlet 14.

[0102] In some implementations, please refer to Figure 3 and Figure 5 The flow divider 26 includes multiple flow divider blades 44, which are evenly spaced in the circumferential direction.

[0103] This can improve the uniformity of atomization.

[0104] Optionally, in one embodiment, the diverter 26 includes a base 46 and diverter blades 44. The base 46 is fixedly connected to the turntable body 12, and the diverter blades 44 are disposed on the top surface of the base 46 and communicate with the liquid inlet 14. The base 46 is fixedly connected to the rotating shaft 24. When the turntable assembly 100 is working, the rotating shaft 24 drives the diverter 26 and the turntable body 12 to rotate synchronously. When the diverter blades 44 rotate, they divert the liquid introduced from the liquid inlet 14 to multiple guide ribs 22.

[0105] Multiple flow divider blades 44 are evenly spaced in the circumferential direction, so that the multiple flow divider blades 44 are evenly arranged on the rotation axis 24 of the flow divider 26, thereby evenly dividing the introduced liquid and making the liquid more evenly distributed to the multiple guide ribs 22 in the circumferential direction, so that the amount of atomized liquid sprayed from the liquid outlet 16 is more uniform and the atomization uniformity is improved.

[0106] Optionally, the diverter 26 is a one-piece molded structure.

[0107] Secondly, please combine Figure 3 and Figure 6 The turntable assembly 100 provided in this application includes:

[0108] Turntable body 12, the turntable body 12 has an inner circumferential surface 18 and an outer circumferential surface 20;

[0109] Liquid inlet 14 is located on the turntable body 12 and is used to introduce materials.

[0110] Multiple liquid outlets 16, including a first group of liquid outlets 38 and a second group of liquid outlets 40. The first group of liquid outlets 38 is located at a first height on the outer peripheral surface 20 of the turntable body 12, and the second group of liquid outlets 40 is located at a second height on the outer peripheral surface 20 of the turntable body 12. The first group of liquid outlets 38 is closer to the liquid inlet 14 than the second group of liquid outlets 40. The diameter corresponding to the first height is smaller than the diameter corresponding to the second height.

[0111] The inner circumferential surface 18 of the turntable body 12 is provided with a plurality of protruding guide ribs 22 to guide the material introduced into the liquid inlet 14 to a plurality of liquid outlets 16.

[0112] In the aforementioned design of the turntable assembly 100, on the one hand, the diameter of the first set of liquid outlets 38 and the second set of liquid outlets 40 on the outer peripheral surface 20 of the turntable body 12 is smaller than that of the second set of liquid outlets 40 at the first set of liquid outlets 38, which is closer to the liquid inlet 14. This facilitates the smooth flow and dispersion of materials from the liquid inlet 14 to multiple liquid outlets 16. On the other hand, the guide ribs 22 guide the materials from the liquid inlet 14 to multiple liquid outlets 16 at different heights, which is beneficial for the height diversion and particle size refinement of the materials. The combination of these two effects takes into account both the spray flow rate requirements and the spray uniformity requirements, and the structure is simple.

[0113] Specifically, in Figure 6 In the embodiment shown, on the outer peripheral surface 20 of the turntable body 12, the height of the first set of liquid outlets 38 is greater than the height of the second set of liquid outlets 40. Therefore, when liquid is sprayed out from the liquid outlet 16, a spray layer is formed at the first set of liquid outlets 38 and another spray layer is formed at the second set of liquid outlets 40. The turntable body 12 can spray at least two spray layers simultaneously in the height direction, thereby improving the atomization amount and spray range.

[0114] exist Figure 6 In the rotating disc body 12, three sets of liquid outlets 16 are formed on the outer peripheral surface 20, namely K1 group liquid outlet 16, K2 group liquid outlet 16, and K3 group liquid outlet 16 from top to bottom. When the rotating disc body 12 rotates, three spray layers can be formed. The first set of liquid outlets 38 can be at least one of K1 group liquid outlet 16 and K2 group liquid outlet 16, and the second set of liquid outlets 40 can be at least one of K2 group liquid outlet 16 and K3 group liquid outlet 16. Figure 6 In the embodiment shown, the first set of liquid outlets 38 includes K1 set of liquid outlets 16 and K2 set of liquid outlets 16, and the second set of liquid outlets 40 may be K3 set of liquid outlets 16.

[0115] The diameter at the first height is smaller than that at the second height, which facilitates the flow and dispersion of material from the inlet 14 to the multiple outlets 16, thereby ensuring the atomization effect and atomization range.

[0116] For an explanation of the guide rib 22, please refer to the above-described implementation method and the explanation of its beneficial effects of the turntable assembly 100. To avoid redundancy, it will not be elaborated in detail here.

[0117] Thirdly, the spraying mechanism provided in this application includes a power component and a turntable assembly 100 of any of the above embodiments. The turntable assembly 100 rotates under the drive of the power component so that the liquid is thrown out from multiple liquid outlets 16 under the action of centrifugal force.

[0118] Optionally, in one embodiment, the power assembly may include a motor that can be connected to the rotating shaft 24, and the turntable assembly 100 can rotate under the drive of the motor so that the liquid is thrown out from the multiple liquid outlets 16 under the action of centrifugal force.

[0119] Fourthly, the mobile platform provided in this application includes a platform body and a spraying mechanism as described in the above embodiments. The spraying mechanism is mounted on the platform body.

[0120] In the aforementioned spraying mechanism and movable platform, on the one hand, the projection of the vertical cross-section of the turntable body 12 is roughly trapezoidal, with the end near the liquid inlet 14 corresponding to the short side of the trapezoid and the other end away from the liquid inlet 14 corresponding to the long side of the trapezoid. The shape design of the turntable body 12 is conducive to the smooth flow and dispersion of the liquid. On the other hand, combined with the guidance of the guide ribs 22, the liquid is guided from the liquid inlet to multiple liquid outlets 16 at different heights, which is conducive to the height division of the liquid and the refinement of the particle size. The combination of these two aspects takes into account both the spray flow rate requirements and the spray uniformity requirements, and the structure is simple.

[0121] Specifically, the mobile platform includes, but is not limited to, vehicles, ground robots (such as robotic vacuum cleaners), and aircraft. The mobile platform includes a platform body, on which a spraying mechanism can be mounted. Optionally, the mobile platform also includes a liquid storage tank and a pump, both mounted on the platform body. The pump is connected to the liquid storage tank and the inlet 14 via a pipe. When the pump is operating, it can transport liquid from the storage tank to the inlet 14, from which the liquid is guided into a high-speed rotating turntable body 12. The turntable body 12 atomizes the liquid, and the atomized liquid is sprayed out from the outlet 16.

[0122] In some implementations, the mobile platform includes an aircraft.

[0123] Therefore, aircraft can spray atomized liquid from the air, with a large spraying range and good effect.

[0124] Optionally, in one embodiment, the aircraft may be an agricultural drone. The agricultural drone may include a storage tank and a pump, with the pump connected to the storage tank and the inlet 14 via a pipe. When performing agricultural operations, the agricultural drone can deliver the pesticide solution in the storage tank to a high-speed rotating turntable assembly 100 in the air, whereby the turntable body 12 atomizes the solution and sprays it onto the crops.
