DETAILED DESCRIPTION

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0042] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0043] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0045] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] To ensure efficient feeding of materials by the drone's feeding assembly, the drone's spreading equipment is typically equipped with a drive mechanism. This drive mechanism comprises a drive assembly and a transmission assembly housed within a housing. The drive assembly drives the transmission assembly, which in turn drives the feeding assembly to perform feeding operations. However, due to the significant differences in the operating environments of the transmission and drive assemblies, the transmission assembly often interferes with the proper functioning of the drive assembly.

[0047] The inventors analyzed the above problems and found that, on the one hand, the transmission assembly needs to be frequently replaced, maintained or repaired, and therefore the chamber where the transmission assembly is installed needs to be frequently in contact with the external environment. The precision requirements of the transmission assembly are low, and the precision requirements of the drive assembly are high. Although frequent contact with the external environment will not affect the transmission effect of the transmission assembly, it will affect the precision of the drive assembly, making it difficult to maintain its precision at a high level; on the other hand, the transmission assembly usually requires a large amount of built-in lubricating oil or lubricant to ensure the transmission effect, and when the lubricating oil or lubricant splashes onto the drive assembly, it will affect the normal operation of the drive assembly, and in severe cases, it may even damage the drive assembly.

[0048] In light of this, this embodiment provides a drone in which the chambers for mounting the drive assembly and the transmission assembly of the spreading device are separated. This effectively reduces the impact of the transmission assembly installation environment and the external environment on the drive assembly, thereby ensuring the operating quality and service life of the drive assembly, and fully guaranteeing spreading efficiency and quality. The following is a detailed description of the structure of this drone.

[0049] Figure 1 This is a schematic diagram of the structure of the drone 100 provided in this embodiment. Figure 1 This embodiment provides a drone 100 that is used to carry a spreading device 113 to perform material spreading operations. Of course, in other embodiments, the drone 100 can also carry other operating equipment to perform other agricultural operations, such as a spraying device to spray pesticides, etc. This embodiment is not limited to this.

[0050] Please refer to the Figure 1 In this embodiment, the UAV 100 specifically includes a fuselage 101 , a payload frame 103 , a landing gear 105 , a storage box 107 and a spreading device 111 .

[0051] The fuselage 101 is the main structure of the drone 100. The payload frame 103 is located below the fuselage 101 and is used to mount the landing gear 105. A material storage box 107 is located within the payload frame 103 and is used to store material. The storage box 107 has a feed port 109 and a discharge port (not shown). The feed port 109 can be one or more and is used to input material. A spreading device 111 is located below the storage box 107 and is connected to the discharge port. The discharge port can output material to the spreading device 111, facilitating the spreading operation.

[0052] Figure 2 An exploded schematic diagram of the spreading device 111 provided in this embodiment; Figure 3 This is a partial structural diagram of the spreading device 111 provided in this embodiment. Figure 2 and Figure 3 In this embodiment, the sowing equipment 111 includes a feeding device 121 and a sowing device 113. The feeding device 121 is connected to the storage box 107, and is used to receive the material output from the discharge port of the storage box 107 and transport the material to the sowing device 113. The sowing device 113 can broadcast the material to complete the sowing operation.

[0053] In detail, Figure 4 The structure of the mounting housing 123 of the feeding device 121 provided in this embodiment is schematically shown. Figure 1 ; Figure 5 The structure of the mounting housing 123 of the feeding device 121 provided in this embodiment is schematically shown. Figure 2See Figures 2 to 5 In this embodiment, the feeding device 121 includes a mounting shell 123, a feeding mechanism and a driving mechanism.

[0054] The mounting housing 123 is a flat, cylindrical structure, fixedly connected to the body 101 to ensure the stability of the entire feeding mechanism, thereby ensuring the stability of the feeding and spreading operations. Furthermore, a feed inlet 135 is provided on the periphery of the mounting housing 123. The feed inlet 135 is opposite and connected to the discharge port of the storage bin 107 to receive the material outputted by the storage bin 107. Furthermore, the mounting housing 123 also defines two mounting chambers 153, which communicate with the feed inlet 135, for mounting the feeding mechanism. Furthermore, a transmission chamber 125 is provided at the end of the mounting housing 123, and a drive chamber 127 is provided on the periphery of the mounting housing 123 for mounting the drive mechanism.

[0055] The feeding mechanism includes two feeding assemblies 129, each of which is at least partially installed in the two mounting chambers 153 of the mounting shell 123. Each feeding assembly 129 includes a feeding shell 131 and a feeding member 133. The feeding shell 131 is generally cylindrical in structure and can at least partially extend into the corresponding mounting chamber 153 of the mounting shell 123. At the same time, the feeding shell 131 is provided with an inlet 137 and an outlet (not shown). The inlet 137 is located on the peripheral side of the feeding shell 131, opposite to and connected to the feed port 135, and is used to receive material input from the feed port 135. The outlet is located at the end of the feeding shell 131 and is used to output material. The feeding member 133 is movably provided in the feeding shell 131 and is used to output material input from the inlet 137 to the outlet.

[0056] Correspondingly, the number of spreading devices 113 corresponds to the number of two feed assemblies 129. Each spreading device 113 is located at the end of the corresponding discharge housing and communicates with the outlet of the corresponding feed assembly 129 to spread the material output from the corresponding outlet. Each spreading device 113 includes a spreading motor 115, a spreading disc 119, and a protective cover 117. The protective cover 117 is connected to and communicates with the outlet of the corresponding feed assembly 129 to receive the material output from the corresponding outlet. The spreading motor 115 is located outside the protective cover 117, and the spreading disc 119 is located inside the protective cover 117. The spreading motor 115 can drive the spreading disc 119 to rotate to broadcast the material output from the outlet, thereby completing the spreading operation.

[0057] Of course, in other embodiments, the number of the feeding assembly 129 can also be set to one. When the number of 129 is set to one, the installation shell 123 only needs to be provided with one installation chamber 153, and the number of the spreading device 113 is also correspondingly set to one, which is not limited in this embodiment.

[0058] The drive mechanism specifically includes a drive assembly 139 and a transmission assembly 141. The drive assembly 139 is disposed within the drive chamber 127, while the transmission assembly 141 is disposed within the transmission chamber 125, i.e., the two are separated. The drive assembly 139 is in transmission connection with the transmission assembly 141 via an output shaft 151. The transmission assembly 141 is also in transmission connection with the feed members 133 of the two feed assemblies 129. Driven by the drive assembly 139, the two feed assemblies 129 are driven simultaneously to transport material. This allows the two feed assemblies 129 to deliver material to their respective spreading devices 113, allowing both spreading devices 113 to simultaneously perform spreading operations, ensuring a uniform spreading range.

[0059] By this arrangement, the drive assembly 139 and transmission assembly 141 of the feeding device 121 are located in the separated transmission chamber 125 and drive chamber 127, respectively. Therefore, lubricating oil or other liquids such as lubricants in the environment where the transmission assembly 141 is installed are unlikely to splash or move into the drive chamber 127, thereby less likely to affect the accuracy and normal operation of the drive assembly 139. This can reduce the chance of damage to the drive assembly 139, extend the service life of the drive assembly 139, and ensure the efficiency and quality of feeding and sowing. Furthermore, the transmission assembly 141 and the drive assembly 139 are separated. When the transmission chamber 125 is opened to replace, maintain, or repair the transmission assembly 141, the external environment will not affect the drive assembly 139 in the drive chamber 127. Therefore, the drive assembly 139 can maintain a high level of accuracy, further ensuring the efficiency and quality of feeding and sowing.

[0060] Figure 6 This is a schematic diagram of the structure of the driving assembly 139 of the feeding device 121 provided in this embodiment. Figure 2 、 Figure 3 as well as Figure 6In this embodiment, the drive assembly 139 includes a reduction motor 149, which is a composite structure composed of a motor and a reducer. The output shaft 151 of the reduction motor 149 is in transmission connection with the transmission assembly 141. Combining the motor and reducer into the reduction motor 149 makes its structure more compact and reliable, facilitates the direct output of power to the transmission assembly 141 after deceleration, and can ensure transmission efficiency and quality. At the same time, because the reduction portion of the reduction motor 149 has high precision requirements, the reduction motor 149 and the transmission assembly 141 are separated. This can also effectively reduce the impact of lubricating oil or lubricant in the transmission chamber 125, or impurities in the external environment, on the reduction motor 149, effectively ensuring the reduction precision and quality, thereby fully ensuring the reliability and stability of the feeding and spreading operations. Of course, in other embodiments, the drive assembly 139 can also be configured to include a motor and a reducer, with the output shaft of the motor in transmission connection with the reducer, and the output shaft 151 of the reducer in transmission connection with the transmission assembly 141 to ensure transmission efficiency, which is not limited to this embodiment.

[0061] Please refer to the Figures 2 to 5 In this embodiment, the drive chamber 127 is formed between the outer walls of the two mounting chambers 153 of the mounting housing 123 and is disposed adjacent to the transmission chamber 125. A connecting hole 163 is formed in the wall of the transmission chamber 125, communicating with the drive chamber 127. The output shaft 151 of the reduction motor 149 is adapted to fit within the connecting hole 163 and, after passing through the connecting hole 163, is in transmission connection with the transmission assembly 141. The connecting hole 163 formed in the wall of the transmission chamber 125, adapted to fit the output shaft 151, allows the transmission chamber 125 and the drive chamber 127 to be separated to the greatest extent possible. This ensures that neither the environment within the transmission chamber 125 nor the external environment easily affects the drive assembly 139 within the drive chamber 127, thereby further ensuring the reliability, service life, and operational precision of the drive assembly 139, thereby fully guaranteeing the efficiency and quality of feeding and spreading.

[0062] As an optional solution, in this embodiment, each transmission chamber 125 is a semi-enclosed chamber having a first opening 165. The feeding device 121 also includes a first cover plate 159, which covers the transmission chamber 125 to isolate the transmission chamber 125 from the external environment, thereby ensuring the accuracy and proper operation of the transmission assembly 141, ensuring transmission efficiency, and thus ensuring feeding and spreading efficiency. Furthermore, the provision of the first cover plate 159 facilitates replacement, maintenance, and repair of the transmission assembly 141, and facilitates installation and removal operations.

[0063] Furthermore, in this embodiment, the drive chamber 127 is a semi-enclosed chamber having a second opening 167, and the feeding device 121 further includes a second cover plate 161. The second cover plate 161 is disposed outside the drive chamber 127 to further isolate the drive assembly 139 from the external environment, thereby further improving the reliability and safety of the drive assembly 139, reducing the impact of the external environment on the driving environment, ensuring its operating accuracy, and thus further improving feeding and spreading efficiency. Furthermore, the provision of the second cover plate 161 facilitates replacement, maintenance, and repair of the drive assembly 139, and also facilitates installation and removal operations.

[0064] Please refer again Figure 2 and Figure 3 In this embodiment, the transmission assembly 141 specifically includes a first gear 143, a second gear 145, and a third gear 147, which are sequentially meshed and disposed within the transmission chamber 125. The second gear 145 is in transmission connection with the output shaft 151 of the reduction motor 149, the first gear 143 is in transmission connection with one of the two feed members 133, and the third gear 147 is in transmission connection with the other of the two feed members 133. This allows the reduction motor 149 to rotate the second gear 145, thereby simultaneously driving the rotation of the first gear 143 and the third gear 147, thereby simultaneously driving the movement of the two feed members 133, thereby discharging material input from the inlet 137 to the outlet, thereby facilitating the spreading device 113 at the outlet to perform a spreading operation.

[0065] It should be noted that in this embodiment, the first gear 143 and the third gear 147 are identical in size and structure to ensure uniform feeding of the two feeding members 133, thereby ensuring uniform spreading of the two sowing devices 113, and effectively improving sowing quality. Of course, the structures of the first gear 143, the second gear 145, and the third gear 147 can also be directly configured to be identical to facilitate the manufacture and processing of the gears and save manufacturing and processing costs. In addition, in other embodiments, the size of the middle second gear 145 can be set smaller, and the size of the first gear 143 and the third gear 147 on both sides can be set larger, so that the transmission assembly 141 also has a deceleration function, can adapt to the user's sowing needs, and ensure sowing quality. This is not limited in this embodiment.

[0066] It should also be noted that, in other embodiments, the transmission assembly 141 can also be set as a matching structure of a pulley and a transmission belt, or a matching structure of a sprocket and a chain. For example, when it is set as a pulley and a transmission belt, the two pulleys can be respectively connected to the two feeding members 133, and any one of the two pulleys is connected to the output shaft 151 of the reduction motor 149. The transmission belt is sleeved outside the two pulleys so that when any one pulley rotates, the other pulley can be driven to rotate, thereby realizing synchronous feeding and then synchronous sowing to ensure sowing efficiency and quality. This embodiment is not limited to this.

[0067] Figure 7 This is a partial structural diagram of the feeding device 121 provided in this embodiment. Figure 7 In this embodiment, the feed member 133 is a feed auger. The feed member 133 specifically includes a feed shaft 155 and blades 157 spirally arranged around the feed shaft 155. The first gear 143 and the third gear 147 are respectively connected to the two feed shafts 155 to drive the blades 157 to rotate, thereby conveying the material to the outlet for the corresponding spreading device 113 to perform the spreading operation.

[0068] It should be noted that in this embodiment, the two feed members 133 have identical structures. Identical structures mean that the feed shafts 155 of both are of the same length, the feed shafts 155 have the same dimensions relative to the inlet 137, and the blades 157 have the same pitch, height, length, and length relative to the inlet 137. This arrangement ensures that the two feed members 133, driven by a single reduction motor 149, can uniformly feed material, thereby ensuring that the two spreading devices 113 can perform uniform spreading operations, thereby improving feeding and spreading efficiency and increasing agricultural work efficiency.

[0069] It should also be noted that in this embodiment, the two feed shafts 155 can be arranged in parallel, and the two blades 157 can be arranged to rotate in opposite directions. This arrangement not only makes the power transmission process more stable and reliable, and the feeding and spreading operations more uniform, but also effectively increases the spreading range, ensuring that the two blades 157 spread the material in two complementary directions, thereby fully improving the spreading quality and efficiency.

[0070] The following is a detailed description of the installation process, working principle, and beneficial effects of the drone 100 provided in an embodiment of the present invention:

[0071] When installing the drone 100, the payload frame 103 can be first installed on the fuselage 101, and the spreading device 111 can be installed. Then, the spreading device 111 can be installed on the fuselage 101 and connected to the storage box 107. Then, the storage box 107 and the landing gear 105 can be installed on the payload frame 103. When installing the spreading device 111, the reduction motor 149 can be first installed in the drive chamber 127 of the installation housing 123, the two feeding members 133 can be installed in the two installation chambers 153 respectively, and the first gear 143, the second gear 145 and the third gear 147 can be installed in the transmission chamber 125. The second gear 145 is connected to the output shaft 151 of the reduction motor 149, and the first gear 143 and the third gear 147 are connected to the feeding shafts 155 of the two feeding members 133 respectively.

[0072] When performing sowing operations, the reduction motor 149 and the sowing motor 115 can be started. The reduction motor 149 drives the second gear 145 to rotate, thereby simultaneously driving the first gear 143 and the third gear 147 to rotate, so as to drive the two feeding parts 133 to rotate at the same time, so as to respectively output the materials input from the inlet 137 from the outlet to the corresponding sowing plate 119. The sowing plate 119 rotates under the drive of the sowing motor 115 to sow the materials.

[0073] In the above process, the feeding device 121 respectively arranges the driving component 139 and the transmission component 141 in the separated transmission chamber 125 and the driving chamber 127, which can not only effectively reduce the impact of the lubricating oil in the installation environment of the transmission component 141 on the driving component 139, but also reduce the impact of the external environment on the driving component 139, thereby fully ensuring the working quality and service life of the driving component 139.

[0074] To sum up, an embodiment of the present invention provides a feeding device 121, a spreading device 111 and a drone 100 in which the chambers for installing the drive component 139 and the chamber for installing the transmission component 141 are separated, which can effectively reduce the impact of the installation environment of the transmission component 141 on the drive component 139, thereby ensuring the working quality and service life of the drive component 139.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
