Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a dispersing device and a UAV. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by onboard computers, either completely or intermittently. They have been widely used in various fields.

[0003] Currently, when drones are used for seeding operations in agriculture, the seeds are dispersed under gravity through a seeding device. Over prolonged operation, this can lead to seed accumulation at the discharge port of the device and uneven distribution, affecting the seeding efficiency. Therefore, improving the seeding efficiency of drone-based seeding devices has become a pressing technical problem to be solved in this field. Summary of the Invention

[0004] This application provides a seeding device and a drone, which can improve the seeding efficiency of the seeding device.

[0005] In a first aspect, a dispensing device is provided, comprising: a hopper component including a first groove with an opening facing the drone; a motor, at least a portion of which is housed in the first groove and connected to the bottom wall of the first groove; and a rotating component including a connecting structure and a sweeping structure, one side of the connecting structure being connected to the side of the motor facing away from the bottom wall, and the other side of the connecting structure being connected to the sweeping structure; wherein at least a portion of the surface of the sweeping structure facing the bottom wall is attached to at least a portion of the surface of the bottom wall facing the drone, the motor is used to drive the rotating component to rotate circumferentially along the motor, and the sweeping structure is inclined relative to the direction of gravity in a plane perpendicular to the rotation direction of the rotating component.

[0006] In this embodiment, a rotating component is provided in the spreading device. This rotating component includes a transfer structure and a sweeping structure. One side of the transfer structure is connected to the side of the motor facing away from the bottom wall, and the other side of the transfer structure is connected to the sweeping structure. At least a portion of the surface of the sweeping structure facing the bottom wall is attached to at least a portion of the surface of the bottom wall facing the drone. On a plane perpendicular to the rotation direction of the rotating component, the sweeping structure is inclined relative to the direction of gravity. Thus, when the motor drives the rotating component to rotate, the sweeping structure can push the material in the hopper component to move, thereby reducing the risk of material residue or accumulation inside the hopper component, facilitating the normal operation of the spreading device and improving the spreading efficiency of the spreading device.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the sweeping structure is a plate-like structure, and the sweeping structure includes a first through hole penetrating the sweeping structure along a direction perpendicular to the thickness of the sweeping structure.

[0008] In this embodiment of the application, by setting the sweeping structure as a plate-shaped structure, and by setting the sweeping structure to include a first through hole penetrating the sweeping structure along a direction perpendicular to the thickness of the sweeping structure, the sweeping structure can operate at a lower power when the rotating component is driven by the motor, so as to balance the spreading efficiency and operating power of the spreading device, reduce the power consumption of the spreading device, and improve the working efficiency of the spreading device.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the sweeping structure includes an interconnected main body and an extension, the extension being located on the side of the main body near the bottom wall, at least a portion of the surface of the extension facing the bottom wall being attached to at least a portion of the surface of the bottom wall facing the drone, and the dimension of the extension gradually decreasing along the direction of gravity in a plane perpendicular to the rotation direction of the sweeping structure.

[0010] In this embodiment, the sweeping structure is configured to include a main body and an extension, with the extension located on the side of the main body near the bottom wall. At least a portion of the surface of the extension facing the bottom wall is attached to at least a portion of the surface of the bottom wall facing the drone. In a plane perpendicular to the rotation direction of the sweeping structure, the dimension of the extension gradually decreases along the direction of gravity. This allows the sweeping structure to smoothly push the material when the rotating component is driven by a motor, effectively reducing the risk of material residue or accumulation inside the hopper component. This facilitates the normal operation of the spreading device and improves the spreading efficiency of the spreading device.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, an extension portion is provided on the outer periphery of the extension portion away from the main body portion, and the extension portion is bent toward the geometric center of the extension portion. Thus, in the embodiments of this application, by providing an extension portion on the outer periphery of the extension portion away from the main body portion, and by bending the extension portion toward the geometric center of the extension portion, the working efficiency of the sweeping structure in pushing materials can be effectively improved, the risk of material residue or accumulation inside the hopper component can be reduced, and the spreading efficiency of the spreading device can be improved.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the dispersing device further includes a baffle component located on the side of the hopper component away from the drone.

[0013] In this embodiment of the application, by providing a baffle component in the spreading device, and the baffle component being located on the side of the hopper component away from the drone, the damage to the hopper component in the spreading device caused by external impacts can be effectively reduced during the use of the spreading device, thereby improving the performance of the spreading device.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the bottom wall includes a second through hole extending through the bottom wall along its thickness direction, and the baffle member includes a third through hole extending through the baffle member along its thickness direction. When the dispensing device is in the open state, at least a portion of the orthographic projection of the second through hole overlaps with at least a portion of the orthographic projection of the third through hole in a plane perpendicular to the thickness direction of the bottom wall. When the dispensing device is in the closed state, in a plane perpendicular to the thickness direction of the bottom wall, the orthographic projection of the portion of the baffle member other than the third through hole covers the orthographic projection of the second through hole.

[0015] In this embodiment, by providing a second through hole penetrating the bottom wall along its thickness direction and a third through hole penetrating the baffle component along its thickness direction, when the spreading device is in the open state, at least a portion of the orthographic projection of the second through hole and at least a portion of the orthographic projection of the third through hole overlap on a plane perpendicular to the thickness direction of the bottom wall. This allows the sweeping structure to smoothly push the material and spread it to the outside of the spreading device through the second and third through holes when the rotating component is driven by the motor. Furthermore, when the spreading device is in the closed state, on a plane perpendicular to the thickness direction of the bottom wall, the orthographic projection of the portion of the baffle component other than the third through hole covers the orthographic projection of the second through hole. That is, the baffle component can block the second through hole in the bottom wall, thereby reducing the risk of material falling from the hopper component when the spreading device is in the closed state, thus improving the performance of the spreading device.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the spreading device further includes a driving component disposed on the sidewall of the first groove away from the first groove, the driving component being used to drive the bottom wall and / or the baffle component to rotate circumferentially along the motor to control the connection or closure between the second through hole and the third through hole.

[0017] In this embodiment of the application, by providing a driving component in the spreading device, and the driving component being disposed on the side wall of the first groove away from the first groove, the driving component is used to drive the bottom wall and / or the baffle component to rotate circumferentially along the motor, so as to facilitate the adjustment of the bottom wall and / or the baffle component according to the usage requirements, so as to control the connection or closure between the second through hole and the third through hole, thereby improving the performance of the spreading device.

[0018] In a second aspect, a drone is provided, including the dispersing device of the first aspect and any implementation thereof. Attached Figure Description

Figure 2 A schematic diagram of the structure of a spreading device 1 provided in another embodiment of this application is shown. Figure 3 An exploded structural diagram of a dispersing device 1 according to an embodiment of this application is shown. Exemplarily, the... Figure 1 and Figure 2 The diagram shows the structure of the same spreading device 1 at different angles. Figure 3 Can be Figure 1 or Figure 2 The diagram shows the explosive structure of the dispersing device 1.

[0040] In some implementations, such as Figures 1 to 3 As shown, the spreading device 1 includes: a hopper component 110, a motor 120, and a rotating component 130. The hopper component 110 includes a first groove 112 with an opening 111 facing the drone. At least a portion of the motor 120 is accommodated in the first groove 112 and connected to the bottom wall 113 of the first groove 112. The rotating component 130 includes a connecting structure 131 and a sweeping structure 132. One side of the connecting structure 131 is connected to the side of the motor 120 facing away from the bottom wall 113, and the other side of the connecting structure 131 is connected to the sweeping structure 132. At least a portion of the surface of the sweeping structure 132 facing the bottom wall 113 is attached to at least a portion of the surface of the bottom wall 113 facing the drone. The motor 120 drives the rotating component 130 to rotate circumferentially. On a plane perpendicular to the rotation direction of the rotating component 130, the sweeping structure 132 is inclined relative to the direction of gravity.

[0041] It should be understood that the hopper component 110 in this embodiment may be a groove structure with an opening 111 at one end, and the groove may be... Figures 1 to 3 The first groove 112 shown can be used to accommodate various materials, such as seeds, powders, or solid fertilizer granules. The bottom wall 113 of the first groove 112 may be provided with a through-hole structure, that is, the aforementioned materials can be spread outward through the through-hole structure. It should also be understood that the shape of the bottom wall 113 of the first groove 112 can be set according to actual needs on a plane perpendicular to the thickness direction of the bottom wall 113. For example, the shape of the bottom wall 113 can be set as a circle, rectangle, or polygon.

[0042] It should also be understood that the motor 120 in the embodiments of this application may be a DC rotary motor or an AC rotary motor. The motor 120 may be fixedly connected to a portion of the surface of the bottom wall 113 facing the drone. For example, the motor 120 may be disposed in the central region of the surface of the bottom wall 113 facing the drone and welded to the bottom wall 113.

[0043] It should also be understood that the rotating component 130 in this embodiment includes a connecting structure 131 and a sweeping structure 132. One side of the connecting structure 131 can be fixedly connected to the side of the motor 120 opposite to the bottom wall 113. For example, one side of the connecting structure 131 can be welded to the side of the motor 120 opposite to the bottom wall 113. Furthermore, the connecting structure 131 and the sweeping structure 132 can be integrally formed or separately formed. In the case where the connecting structure 131 and the sweeping structure 132 are separately formed, the connecting structure 131 and the sweeping structure 132 can be connected by welding or bolts.

[0044] It should also be understood that the attachment of at least a portion of the surface of the material sweeping structure 132 facing the bottom wall 113 to at least a portion of the surface of the bottom wall 113 facing the drone can mean that at least a portion of the surface of the material sweeping structure 132 facing the bottom wall 113 is in direct contact with but not fixedly connected to at least a portion of the surface of the bottom wall 113 facing the drone.

[0045] It should also be understood that, on a plane perpendicular to the rotation direction of the rotating component 130, the inclined arrangement of the sweeping structure 132 relative to the direction of gravity can mean that at least a portion of the sweeping structure 132 can be configured to be inclined towards the direction of gravity, and the inclination angle of the sweeping structure 132 relative to the direction of gravity can be set according to actual needs. For example, the inclination angle can be set according to the dimensions of the sweeping structure 132 and the height of the first groove 112.

[0046] It should also be understood that the tilting of the sweeping structure 132 relative to the direction of gravity can mean that the tilting angle of the sweeping structure 132 relative to the direction of gravity can be from 0° to 90°. For example, the tilting angle of the sweeping structure 132 relative to the direction of gravity can be set to 45°. As an example, this application embodiment does not limit this.

[0047] In this embodiment, a rotating component 130 is provided in the spreading device 1. The rotating component 130 includes a connecting structure 131 and a sweeping structure 132. One side of the connecting structure 131 is connected to the side of the motor 120 away from the bottom wall 113, and the other side of the connecting structure 131 is connected to the sweeping structure 132. At least a portion of the surface of the sweeping structure 132 facing the bottom wall 113 is attached to at least a portion of the surface of the bottom wall 113 facing the drone. On a plane perpendicular to the rotation direction of the rotating component 130, the sweeping structure 132 is inclined relative to the direction of gravity. Thus, when the motor 120 drives the rotating component 130 to rotate, the sweeping structure 132 can push the material in the hopper component 110 to move, thereby reducing the risk of the material remaining or accumulating inside the hopper component 110, so as to facilitate the normal operation of the spreading device 1 and improve the spreading efficiency of the spreading device 1.

[0048] In some implementations, such as Figures 1 to 3 As shown, the sweeping structure 132 is a plate-shaped structure, and the sweeping structure 132 includes a first through hole 133 that penetrates the sweeping structure 132 along a direction perpendicular to the thickness of the sweeping structure 132.

[0049] It should be understood that the sweeping structure 132 in the embodiments of this application can be configured as a plate-like structure, and the shape of the plate-like structure can be set according to actual needs on a plane perpendicular to the thickness direction of the sweeping structure 132, such as a rectangle or a polygon.

[0050] It should also be understood that the shape of the first through hole 133 can be set according to actual needs. On the plane perpendicular to the thickness direction of the sweeping structure 132, the shape of the first through hole 133 can be set as a circle, rectangle or polygon, etc. It should also be understood that the number of the first through holes 133 on the sweeping structure 132 can be set as one or more. As an example, this application embodiment does not limit this.

[0051] In this embodiment, by setting the sweeping structure 132 as a plate-shaped structure and including a first through hole 133 extending through the sweeping structure 132 along a direction perpendicular to its thickness, the sweeping structure 132 can operate at a lower power when the motor 120 drives the rotating component 130 to rotate, so as to balance the spreading efficiency and operating power of the spreading device 1, reduce the power consumption of the spreading device 1, and improve the working efficiency of the spreading device 1.

[0052] Figure 4 A schematic diagram of the structure of a rotating component 130 provided in an embodiment of this application is shown.

[0053] In some implementations, such as Figure 4 As shown, the sweeping structure 132 includes a main body 134 and an extension 135 connected to each other. The extension 135 is located on the side of the main body 134 near the bottom wall 113. At least a portion of the surface of the extension 135 facing the bottom wall 113 is attached to at least a portion of the surface of the bottom wall 113 facing the drone. In a plane perpendicular to the rotation direction of the sweeping structure 132, the size of the extension 135 gradually decreases along the direction of gravity.

[0054] It should be understood that the main body 134 and the extension 135 of the sweeping structure 132 in the embodiments of this application can be integrally formed or separately formed. When the main body 134 and the extension 135 are integrally formed, the main body 134 and the extension 135 can be formed by stamping. Or when the main body 134 and the extension 135 are separately formed, the main body 134 and the extension 135 can be connected by welding.

[0055] It should also be understood that the attachment of at least a portion of the surface of the extension 135 facing the bottom wall 113 to at least a portion of the surface of the bottom wall 113 facing the drone can mean that the at least a portion of the surface of the extension 135 facing the bottom wall 113 is in direct contact with but not fixedly connected to the at least a portion of the surface of the bottom wall 113 facing the drone.

[0056] It should also be understood that, on a plane perpendicular to the rotation direction of the sweeping structure 132, the gradual decrease in the dimension of the extension 135 along the direction of gravity can mean that the dimension of the extension 135 along the direction of gravity decreases either continuously or discontinuously.

[0057] In this embodiment, the sweeping structure 132 is configured to include a main body 134 and an extension 135, with the extension 135 located on the side of the main body 134 near the bottom wall 113. At least a portion of the surface of the extension 135 facing the bottom wall 113 is attached to at least a portion of the surface of the bottom wall 113 facing the drone. In a plane perpendicular to the rotation direction of the sweeping structure 132, the size of the extension 135 gradually decreases along the direction of gravity. This allows the sweeping structure 132 to smoothly push the material when the motor 120 drives the rotating component 130 to rotate, effectively reducing the risk of material residue or accumulation inside the hopper component 110, thus facilitating the normal operation of the spreading device 1 and improving the spreading efficiency of the spreading device 1.

[0058] In some implementations, such as Figure 4 As shown, an extension portion 136 is provided on the outer periphery of the extension portion 135 away from the main body portion 134, and the extension portion 136 is bent toward the geometric center of the extension portion 135.

[0059] It should be understood that one or more extension portions 136 may be provided on the outer periphery of the extension portion 135 away from the main body portion 134, such as Figure 4 As shown, the extension 135 has three outer extensions 136 on its outer periphery away from the main body 134, and all three outer extensions 136 are bent toward the geometric center of the extension 135.

[0060] It should also be understood that after the extension portion 136 is bent toward the geometric center of the extension portion 135, the angle between the bent extension portion 136 and the direction of gravity can be set according to actual needs. As an example, this application embodiment does not limit this.

[0061] It should also be understood that the extension portion 136 and the extension portion 135 can be integrally formed or separately formed. For example, when the extension portion 136 and the extension portion 135 are integrally formed, the extension portion 136 and the extension portion 135 can be formed by stamping.

[0062] In this embodiment of the application, by providing an extension portion 136 on the outer periphery of the extension portion 135 away from the main body portion 134, and by bending the extension portion 136 toward the geometric center of the extension portion 135, the working efficiency of the sweeping structure 132 in pushing the material can be effectively improved, the risk of the material remaining or accumulating inside the hopper component 110 can be reduced, and the spreading efficiency of the spreading device 1 can be improved.

[0063] In some implementations, such as Figure 1 and Figure 2 As shown, the spreading device 1 also includes a baffle component 140, which is located on the side of the hopper component 110 away from the drone.

[0064] It should be understood that, on a plane perpendicular to the thickness direction of the baffle component 140, the orthographic projection of the baffle component 140 can be greater than the orthographic projection of the bottom wall 113, so as to shield and protect the bottom wall 113.

[0065] It should also be understood that the shape of the baffle component 140 can be set according to actual needs. For example, on a plane perpendicular to the thickness direction of the baffle component 140, the shape of the baffle component 140 can be set as a circle, rectangle or polygon, etc.

[0066] In this embodiment of the application, by providing a baffle component 140 in the spreading device 1, and the baffle component 140 being located on the side of the hopper component 110 away from the drone, the damage to the hopper component 110 in the spreading device 1 caused by external impacts can be effectively reduced during the use of the spreading device 1, thereby improving the performance of the spreading device 1.

[0067] Figure 5 A schematic diagram of the structure of a hopper component 110 provided in another embodiment of this application is shown. Figure 6 A schematic diagram of the structure of a baffle component 140 provided in another embodiment of this application is shown.

[0068] In some implementations, such as Figure 1 , 2As shown in Figures 3, 5, and 6, the bottom wall 113 includes a second through hole 115 extending through the bottom wall 113 along its thickness direction, and the baffle member 140 includes a third through hole 141 extending through the baffle member 140 along its thickness direction. When the spreading device 1 is in the open state, at least a portion of the orthographic projection of the second through hole 115 overlaps with at least a portion of the orthographic projection of the third through hole 141 on a plane perpendicular to the thickness direction of the bottom wall 113. When the spreading device 1 is in the closed state, on a plane perpendicular to the thickness direction of the bottom wall 113, the orthographic projection of the portion of the baffle member 140 other than the third through hole 141 covers the orthographic projection of the second through hole 115.

[0069] It should be understood that the shapes of the second through hole 115 and the third through hole 141 in the embodiments of this application can be set according to actual needs. For example, on a plane perpendicular to the thickness direction of the bottom wall 113, the shapes of the second through hole 115 and the third through hole 141 can be set as circles, rectangles, or polygons, etc. It should also be understood that the number of the second through hole 115 and the third through hole 141 can be set to one or more. Specifically, the number of the second through hole 115 and the third through hole 141 can be set according to actual needs. As an example, the embodiments of this application do not limit this.

[0070] It should also be understood that when the spreading device 1 is in the open state, the overlap of at least a portion of the orthographic projection of the second through hole 115 and at least a portion of the orthographic projection of the third through hole 141 on a plane perpendicular to the thickness direction of the bottom wall 113 can mean that the second through hole 115 can communicate with the third through hole 141 so that the material in the first groove 112 can be spread to the outside of the hopper component 110 through the second through hole 115 and the third through hole 141 in sequence.

[0071] It should also be understood that when the spreading device 1 is in the closed state, the orthographic projection of the portion of the baffle component 140 other than the third through hole 141 covering the orthographic projection of the second through hole 115 on a plane perpendicular to the thickness direction of the bottom wall 113 can mean that the second through hole 115 is sealed by the portion of the baffle component 140 other than the third through hole 141, so that the material is contained inside the first groove 112, reducing the risk of leakage of the material in the first groove 112 when the spreading device 1 is in the closed state.

[0072] In this embodiment, by providing a second through hole 115 penetrating the bottom wall 113 along its thickness direction, and by providing a third through hole 141 penetrating the baffle component 140 along its thickness direction, when the spreading device 1 is in the open state, at least a portion of the orthographic projection of the second through hole 115 and at least a portion of the orthographic projection of the third through hole 141 overlap on a plane perpendicular to the thickness direction of the bottom wall 113. This allows the sweeping structure 132 to smoothly operate when the motor 120 drives the rotating component 130 to rotate. The material is pushed and spread to the outside of the spreading device 1 through the second through hole 115 and the third through hole 141. Secondly, when the spreading device 1 is closed, on the plane perpendicular to the thickness direction of the bottom wall 113, the orthographic projection of the portion of the baffle component 140 other than the third through hole 141 covers the orthographic projection of the second through hole 115. That is, the baffle component 140 can block the second through hole 115 of the bottom wall 113 to reduce the risk of material falling in the hopper component 110 when the spreading device 1 is closed, thereby improving the performance of the spreading device 1.

[0073] In some implementations, such as Figures 1 to 3 As shown, the spreading device 1 also includes a driving component 150, which is disposed on the side wall 114 of the first groove 112 away from the first groove 112. The driving component 150 is used to drive the bottom wall 113 and / or the baffle component 140 to rotate circumferentially along the motor 120, so as to control the connection or closure between the second through hole 115 and the third through hole 141.

[0074] It should be understood that the drive component 150 can be electrically connected to the bottom wall 113 and / or the baffle component 140 to determine whether the bottom wall 113 and / or the baffle component 140 rotates clockwise or counterclockwise in a plane perpendicular to the thickness direction of the bottom wall 113. For example, a first gear structure is provided on the side of the drive component 150 near the bottom wall 113 and / or the baffle component 140, and a second gear structure corresponding to the first gear structure is provided on the outer periphery of the bottom wall 113 and / or the baffle component 140 near the drive component 150, so that the drive component 150 drives the bottom wall 113 and / or the baffle component 140 to rotate circumferentially along the motor 120.

[0075] It should also be understood that the driving component 150 for driving the bottom wall 113 and / or the baffle component 140 to rotate circumferentially along the motor 120 can mean that the driving component 150 can be used to drive the bottom wall 113 and / or the baffle component 140 to rotate clockwise or counterclockwise in a plane perpendicular to the thickness direction of the bottom wall 113, so as to control the connection or closure between the second through hole 115 and the third through hole 141.

[0076] In this embodiment of the application, by providing a driving component 150 in the spreading device 1, and the driving component 150 being disposed on the side wall 114 of the first groove 112 away from the first groove 112, the driving component 150 is used to drive the bottom wall 113 and / or the baffle component 140 to rotate circumferentially along the motor 120, so as to adjust the bottom wall 113 and / or the baffle component 140 according to the usage requirements, so as to control the connection or closure between the second through hole 115 and the third through hole 141, thereby improving the performance of the spreading device 1.

[0077] In some implementations, such as Figure 7 As shown, Figure 7 A schematic diagram of a drone 160 according to an embodiment of this application is shown. The drone 160 includes the dispersing device 1 in any of the above embodiments. Exemplarily, the dispersing device 1 can be connected to the remote controller of the drone 160 via a wireless network or Bluetooth, and the remote controller can be used to control the dispersing device 1 on the drone 160 in real time.

[0078] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
