DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 here can be arranged and designed in various different configurations.

[0043] 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 claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0046] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the related technologies, with the gradual maturity of agricultural operation equipment such as small and medium-sized drones and unmanned vehicles, the efficiency and quality of unmanned sowing operations have been effectively improved. Taking drones as an example, drones are usually equipped with mechanical sowing devices for sowing operations. The sowing devices are equipped with sowing parts, which can be used for sowing operations during the flight of the drones to significantly improve the sowing efficiency. However, since the sowing devices are usually large in size, the sowing devices are inconvenient to transport and store during unmanned sowing operations.

[0049] In view of this, the present embodiment provides an operation device, the spreading device carried by the operation device has a foldable function, so as to facilitate transportation and storage, thereby effectively solving the problem of inconvenience in transportation and storage in the prior art. The structure of the drone is described in detail below.

[0050] Figure 1 The structure of the spreading device 100 provided in this embodiment is shown in FIG. Figure 1 ; Figure 2 The structure of the spreading device 100 provided in this embodiment is shown in FIG. Figure 2 ; Figure 3A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 1 This embodiment provides an operation device, which is a drone, including a fuselage (not shown) and a Figures 1 to 3 The sowing device 100 shown. After the fuselage carries the sowing device 100 and flies to the operation destination, the sowing device 100 can be used to spread materials such as pesticides, fertilizers or seeds to complete various agricultural operations and ensure the efficiency and quality of agricultural operations. Of course, in other embodiments, the sowing device 100 can also be carried on other ground walking equipment such as unmanned vehicles, which will not be described in detail in this embodiment.

[0051] Please refer again Figures 1 to 3 In this embodiment, the spreading device 100 specifically includes a base frame 101 , a material box 107 and a spreading mechanism 113 .

[0052] In detail, in this embodiment, the base frame 101 is the main structure of the entire sowing device 100, which can be used to install the entire sowing device 100 on the fuselage of the drone to improve the stability and safety of the entire sowing device 100 and ensure that the entire sowing device 100 performs normal sowing operations. At the same time, the base frame 101 is generally a rectangular parallelepiped structure, which specifically includes a bottom shell 103 and a support plate 105. The bottom shell 103 is a hollow rectangular parallelepiped structure with an opening, and the support plate 105 is arranged at the opening of the bottom shell 103 and is fixedly connected to the bottom shell 103. Setting the bottom shell 103 as a hollow structure can effectively reduce the mass of the sowing device 100 on the one hand, and on the other hand, some driving or transmission structures can be placed in this hollow structure to ensure its safety and stability, thereby ensuring the orderly progress of the sowing operation.

[0053] In detail, in this embodiment, the material box 107 is arranged on one side of the base frame 101 close to the support plate 105, and is specifically fixedly connected to the bottom shell 103, so that the support plate 105 is located between the bottom shell 103 and the material box 107. The material box 107 is used to store materials such as medicines and seeds, and has an inlet 109 and a discharge port 111. The user can add materials to the material box 107 through the inlet 109, and the discharge port 111 can output the materials to the sowing mechanism 113 for easy sowing operations.

[0054] In detail, in this embodiment, a notch 167 is provided at the end of the base frame 101 formed by the bottom shell 103 and the support plate 105. The spreading mechanism 113 includes a shell 115 and a spreading member 121. The shell 115 is a circular tubular structure. The shell 115 can be rotatably arranged on the base frame 101 through the notch 167, specifically, it can be rotatably arranged on the support plate 105, so as to be folded or unfolded relative to the entire base frame 101. At the same time, the shell 115 has an inlet 117, and the inlet 117 of the shell 115 is connected to the material box 107. The spreading member 121 is arranged on the shell 115, and an outlet 119 is provided at a position opposite to the shell 115 and the spreading member 121. The spreading member 121 is used to spread the material output from the outlet 119. Through such an arrangement, when the shell 115 is unfolded relative to the base frame 101, normal sowing operations can be carried out to ensure the sowing width of the sowing mechanism 113, thereby ensuring the sowing efficiency and quality of the UAV; and when the shell 115 is folded relative to the base frame 101, the volume of the sowing mechanism 113 can be reduced, thereby facilitating the transportation and storage of the sowing mechanism 113, thereby improving the convenience and reliability of transportation and storage of the UAV.

[0055] It should be noted that, in this embodiment, there are multiple sowing members 121, and the multiple sowing members 121 are sequentially arranged along the extension direction of the housing 115. An outlet 119 is provided at a position of the housing 115 relative to each sowing member 121, so that each sowing member 121 can be used to sow the material output from the corresponding outlet 119, so as to fully improve the sowing width and ensure the sowing efficiency and quality of the drone.

[0056] More specifically, in this embodiment, a notch 167 is provided on both sides of the base frame 101, and a material discharge port 111 is provided on both sides of the end of the material box 107 close to the bottom shell 103. Correspondingly, the spreading device 100 specifically includes two spreading mechanisms 113, which are located on both sides of the material box 107 and are connected to the two material discharge ports 111 one by one. The two shells 115 are rotatably provided on the support plate 105 through the notches 167 at the corresponding positions, so that they can be close to each other (such as Figure 2 ) to ensure the convenience of transportation and storage, or when they are far away from each other (as shown in FIG. Figure 1 As shown in FIG. 1 , the spreading device 100 is simultaneously unfolded relative to the base frame 101 to effectively increase the spreading range of the drone and ensure the spreading efficiency and quality. Of course, in other embodiments, the spreading device 100 may also include multiple spreading mechanisms 113, such as three or four, which will not be described in detail in this embodiment.

[0057] As an optional solution, in this embodiment, the housing 115 of each spreading mechanism 113 has an unfolded position (such as Figure 1) and a folded position relative to the base frame 101 (as shown Figure 2 At the same time, when the housing 115 is in the unfolded position, the housing 115 is connected to the discharge port 111, and the material in the material box 107 can be input into the housing 115 through the discharge port 111 and the inlet 117, and then output to the spreading member 121 through the outlet 119 of the housing 115, so as to be spread by the spreading member 121. When the housing 115 is in the folded position, the housing 115 is separated from the discharge port 111. With such an arrangement, on the one hand, since the shell 115 is only used for spreading operation when it is in the unfolded position, the shell 115 is connected to the discharge port 111 when it is unfolded, which can avoid leakage or accidental spreading in the folded position for transportation and storage; on the other hand, when the shell 115 is in the folded position, since the shell 115 is separated from the discharge port 111, the entire material box 107 can be cleaned at this time. For example, cleaning water can be directly introduced into one of the inlet 109 and the outlet, and the cleaned liquid can be discharged through the other of the inlet 109 and the outlet, so as to effectively clean the residue in the material box 107, thereby ensuring the cleanliness of the material for the next spreading operation, and then ensuring the spreading quality and efficiency.

[0058] Figure 4 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 2 ; Figure 5 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 3 ; Figure 6 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 4 ; Figure 7 for Figure 6 A local enlarged view of point I; Figure 8 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 5 . See Figures 4 to 8 In this embodiment, each housing 115 is rotatably connected to the support plate 105 of the base frame 101 through a first rotation shaft 141. Part of the first rotation shaft 141 is located in the hollow structure of the bottom shell 103, and the other part of the first rotation shaft 141 passes through the support plate 105 and is located outside the hollow structure of the bottom shell 103 to be fixedly connected to the housing 115. Through such an arrangement, when the first rotation shaft 141 rotates relative to the support plate 105, the housing 115 can be driven to rotate synchronously.

[0059] at the same time, Fig. 9 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 6 . See Fig. 9In this embodiment, the spreading mechanism 113 further includes a conveying assembly, which includes a conveying motor 145 and a feeding auger 147. The conveying motor 145 is rotatably disposed on the support plate 105 of the base frame 101 through a second rotating shaft 155, and the conveying motor 145 is located outside the hollow structure of the bottom shell 103, and specifically between the support plate 105 and the material box 107. Part of the second rotating shaft 155 is disposed in the hollow structure of the bottom shell 103, and the other part passes through the support plate 105 and is located outside the hollow structure of the bottom shell 103, so as to be fixedly connected with the conveying motor 145. In addition, the feeding auger 147 is extended and disposed in the housing 115, and is coaxially disposed with the housing 115. The feeding auger 147 includes a shaft body 151 that is detachably matched with the output shaft of the conveying motor 145 and a spiral blade 153 disposed on the circumferential edge of the shaft body 151. When the shell 115 is unfolded relative to the base frame 101 and the UAV performs a sowing operation, the output shaft of the conveying motor 145 cooperates with and is transmission-connected to the shaft 151 of the unloading auger 147 to drive the unloading auger 147 to rotate, so as to output the material input from the inlet 117 of the shell 115 to each outlet 119, so as to facilitate sowing by the sowing member 121.

[0060] Furthermore, in order to ensure that the output shaft of the conveying motor 145 can be detachably matched with the shaft body 151, in this embodiment, the end of the output shaft of the conveying motor 145 close to the shaft body 151 can be set as a flat portion 183 (that is, the end of the output shaft is roughly in a "one" structure), and a connecting hole 185 is provided at one end of the shaft body 151 close to the output shaft, and a slot communicating with the connecting hole 185 is also provided at the end of the shaft body 151 (not shown in the figure). Through such a setting, when the flat portion 183 of the conveying motor 145 is plugged into the connecting hole 185, the two can be combined to perform transmission cooperation to realize material conveying, and when the conveying motor 145 rotates, the flat portion 183 of the conveying motor 145 can be separated from the connecting hole of the shaft body 151 through the slot, thereby realizing the transmission connection between the conveying motor 145 and the shaft body 151 is disconnected.

[0061] As an optional solution, a mounting ring 149 is further provided on the second rotating shaft 155. The mounting ring 149 is a semi-ring structure that is roughly "C"-shaped. The upper end of the semi-ring structure is fixedly connected to the upper end of the conveying motor 145 through a first mounting shaft 169 that is coaxial with the second rotating shaft 155, and the lower end of the semi-ring structure is sleeved outside the second rotating shaft 155. The installation of the mounting ring 149 effectively improves the stability of the conveying motor 145, thereby ensuring the reliability and safety of the conveying motor 145 during the movement of the second rotating shaft 155 after installation, thereby ensuring the efficient performance of the sowing operation.

[0062] In addition, the spreading mechanism 113 further includes a rotating motor 156 and a transmission assembly. The rotating motor 156 is disposed in the hollow structure of the bottom shell 103, and the output shaft of the rotating motor 156 passes through the support plate 105 and then passes through the hollow structure of the bottom shell 103, and is transmission-connected to both the first rotating shaft 141 and the second rotating shaft 155 through the transmission assembly, and the rotating motor 156 is used to simultaneously drive the conveying motor 145 and the housing 115 to move relative to the base frame 101. By setting the rotating motor 156 and the transmission assembly, when the rotating motor 156 rotates forward, the output shaft of the rotating motor 156 rotates forward, which can drive the first rotating shaft 141 and the second rotating shaft 155 to rotate simultaneously, thereby driving the conveying motor 145 and the shell 115 to rotate relative to the base frame 101 at the same time and fold relative to the base frame 101, and make the flat portion 183 of the output shaft of the conveying motor 145 escape from the connecting hole 185 of the shaft body 151 through the slot, so as to facilitate the transportation and storage of the sowing device 100; similarly, when the rotating motor 156 is reversed, the output shaft of the rotating motor 156 rotates in the opposite direction, which can drive the first rotating shaft 141 and the second rotating shaft 155 to rotate simultaneously. The two rotating shafts 155 rotate in opposite directions at the same time, thereby driving the sowing motor 127 and the shell 115 to rotate relative to the base frame 101 at the same time and unfold relative to the base frame 101, so as to facilitate the connection between the inlet 117 of the shell 115 and the discharge port 111 of the material box 107, and the flat shaft 183 of the output shaft of the conveying motor 145 is plugged into the connecting hole 185 of the shaft body 151 of the discharge auger 147, so that the material can enter the shell 115 after passing through the inlet 117, and be transported by the discharge auger 147 in the shell 115 to each outlet 119, and then be broadcast through the sowing member 121 opposite to the outlet 119, thereby ensuring the sowing efficiency and quality.

[0063] Please refer again Figure 8 In this embodiment, the transmission assembly specifically includes a first gear 157, a second gear 159 and a third gear 161. The first gear 157, the second gear 159 and the third gear 161 are all located in the hollow structure of the bottom shell 103 and are shielded by the support plate 105, so that their safety and stability are effectively guaranteed. At the same time, the first gear 157 is sleeved on the output shaft of the rotating motor 156, the second gear 159 is sleeved outside the second rotating shaft 155 and meshes with the first gear 157, and the third gear 161 is sleeved outside the first rotating shaft 141 and meshes with the second gear 159. When the output shaft of the rotating motor 156 rotates forward or reversely, the first rotating shaft 141 and the second rotating shaft 155 can be driven to rotate simultaneously through the first gear 157, the second gear 159 and the third gear 161, thereby fully ensuring that the housing 115 and the rotating motor 156 can be simultaneously unfolded or folded relative to the base frame 101 to meet various operation requirements.

[0064] It should be noted that Fig.10This is a simplified diagram of the electrical control of the spreading device 100 provided in this embodiment. Fig.10 In this embodiment, the sowing device 100 further includes a main control board 179, which is electrically connected to the rotating motor 156 and the conveying motor 145. The main control board 179 can receive signals from a remote control device 177 such as a mobile phone or a computer, and control the start and stop of the rotating motor 156 and the conveying motor 145. At the same time, a magnetic encoder 181 is provided on the rotating motor 156, and the magnetic encoder 181 is used to detect whether the rotation of the housing 115 is in place, so as to feed back information to the main control board 179, so that the main control board 179 can control the start and stop of the rotating motor 156 and the feeding motor. Specifically, when the sowing device 100 needs to be folded for transportation, the output shaft of the rotating motor 156 can be rotated forward to drive the first rotating shaft 141 and the second rotating shaft 155 to rotate at the same time. When the magnetic encoder 181 indicates that the rotation is in place, the signal is fed back to the rotating motor 156, and the rotating motor 156 sends a signal to the main control board 179 to request to stop rotating, and the main control board 179 controls the rotating motor 156 to stop rotating. Similarly, when the spreading device 100 needs to move from a folded state to an unfolded state, the output shaft of the rotating motor 156 can be reversed to simultaneously drive the first rotating shaft 141 and the second rotating shaft 155 to rotate. When the magnetic encoder 181 indicates that the rotation is in place, the signal is fed back to the rotating motor 156. The rotating motor 156 sends a signal to the main control board 179. The main control board 179 controls the rotating motor 156 to stop rotating and controls the conveying motor 145 to move to convey materials, thereby facilitating the spreading operation of the spreading member 121 to ensure the spreading efficiency and quality.

[0065] Please refer again Figures 5 to 7 In this embodiment, two mounting seats 163 are provided at one end of the material box 107 close to the support plate 105, and the two mounting seats 163 are plugged and matched with the two notches 167 opened on the bottom shell 103 in a one-to-one correspondence. In addition, the mounting seat 163 has a mounting cavity 165, and the end of the mounting cavity 165 has an opening. The end of the shell 115 extends into the mounting cavity 165 after passing through the opening. One end of the first rotating shaft 141 is rotatably provided on the base frame 101, and the other end passes through the cavity wall of the mounting cavity 165 and extends into the mounting cavity 165 to be fixedly connected with the shell 115. Through such a setting, the mounting seat 163 of the material box 107 and the support plate 105 can be connected through the first rotating shaft 141, which can further improve the stability of the entire sowing device 100. At the same time, the side wall of the mounting cavity 165 can also limit the rotation range of the shell 115 relative to the base frame 101 to avoid excessive rotation, so as to ensure the safety and reliability of the entire sowing device 100.

[0066] As an optional solution, in this embodiment, the inner side walls of the installation cavity 165 are all configured as arc-shaped walls. By configuring in this way, when the end of the housing 115 rotates in the installation cavity 165, the side walls of the installation cavity 165 are not easy to scratch or damage the housing 115, which can ensure the safety and reliability of the spreading mechanism 113, thereby ensuring the efficiency and quality of the drone spraying operation.

[0067] Optionally, please refer again to Figures 6 to 8 In this embodiment, a second mounting shaft 171 is provided on the inner side wall of the mounting cavity 165 near the lower end of the support plate 105. The second mounting shaft 171 is a hollow shaft. A third mounting shaft 173 is also provided on the inner side wall of the mounting cavity 165 away from the upper end of the support plate 105. The second mounting shaft 171 and the third mounting shaft 173 are both coaxially arranged with the first rotating shaft 141, and the first rotating shaft 141 can pass through the second mounting shaft 171 after passing through the inner side wall of the mounting cavity 165 to be fixedly connected with the housing 115. A mounting hole 175 is provided at a position of the housing 115 opposite to the third mounting shaft 173. The third mounting shaft 173 is plugged into the mounting hole 175. By providing the second mounting shaft 171 and the third mounting shaft 173, the stability and stability of the housing 115 during the rotation process relative to the base frame 101 are further improved, thereby ensuring the accuracy of its movement between the unfolded position and the folded position, and further ensuring the efficiency and quality of the sowing operation.

[0068] Fig.11 A schematic diagram of the local structure of the spreading device 100 provided in this embodiment Figure 7 . See Fig.11 In this embodiment, the housing 115 of each spreading mechanism 113 has a first end and a second end, the first end is rotatably connected to the support plate 105 of the base frame 101, and the inlet 117 is opened at the first end to communicate with the material box 107, and a plurality of outlets 119 are sequentially and spaced in the direction from the first end to the second end to correspond to the plurality of spreading members 121. For example, each spreading mechanism 113 includes three spreading members 121, and each housing 115 is also correspondingly provided with three outlets 119, so that the materials output from each outlet 119 under the conveyance of the unloading auger 147 can be spread out through the spreading member 121 at the corresponding position to complete the spreading operation.

[0069] In detail, in this embodiment, the shell 115 is specifically a circular tube that is arranged in an inclined manner. That is, relative to the first end of the shell 115, the second end of the shell 115 extends in an inclined manner along a preset direction that is at an angle to the horizontal direction, and specifically extends in an inclined manner downward, so that the material entering from the inlet 117 can move toward the second end under the action of gravity. The shell 115 is arranged in an inclined shape, so that the material is more easily transported to the second end under the dual action of gravity and the unloading auger 147, and it can be ensured that the outlet 119 closer to the second end can also effectively transport the material to the corresponding sowing member 121, so as to fully ensure that the discharge of the material at each position within the sowing width of the sowing device 100 is relatively uniform. Of course, in other embodiments, the circular tube can also be arranged to extend in the horizontal direction, and in this case, the unloading auger 147 is used to rotate to transport the material, and this embodiment will not be repeated.

[0070] Please refer again Fig.11 In this embodiment, along the direction from the first end to the second end of the housing 115, among the multiple outlets 119 opened on the housing 115 and corresponding to the multiple spreading members 121, the size of the outlet 119 adjacent to the second end is larger than the size of the outlet 119 adjacent to the first end. By such an arrangement, the discharge speed and discharge amount of each outlet 119 of the housing 115 are relatively uniform, thereby ensuring the spreading effect and quality.

[0071] As an optional solution, in this embodiment, the sizes of the multiple outlets 119 are successively increased along the direction from the first end of the shell 115 to the second end of the shell 115, so as to further ensure that the discharge speed and discharge amount of each outlet 119 of the shell 115 are relatively uniform, thereby further ensuring the sowing effect and quality.

[0072] Please refer again Figure 6 In this embodiment, the sowing member 121 includes a mounting member 125, a sowing motor 127 and a sowing disc 123. In detail, the mounting member 125 includes a mounting cylinder 129 and a plurality of mounting plates 131. The mounting cylinder 129 is sleeved outside the housing 115. The plurality of mounting plates 131 are bent and connected in sequence to form a roughly "C"-shaped structure. One end of the structure after the plurality of mounting plates 131 are connected is connected to the mounting cylinder 129, and the other end is used to install the sowing motor 127 and the sowing disc 123. The sowing motor 127 is located below the sowing disc 123 and is in transmission connection with the sowing disc 123 to drive the sowing disc 123 to rotate. The sowing motor 127 is electrically connected to the main control board 179, so that after the housing 115 is unfolded relative to the base frame 101, the sowing motor 127 is controlled by the main control board 179 to start and drive the sowing disc 123 to sow the material to complete the sowing operation.

[0073] at the same time, Fig.12 This is a schematic diagram of the structure of the spreading disc 123 of the spreading device 100 provided in this embodiment. Fig.12 In this embodiment, the spreading disc 123 includes a disc body 133 and a plurality of paddles 135 disposed on the disc body 133. The disc body 133 is in driving connection with the spreading motor 127. The middle region 139 of the disc body 133 is opposite to the corresponding outlet 119. The plurality of paddles 135 are arranged at intervals around the circumferential edge of the middle region 139 of the disc body 133, and each paddle 135 extends from the middle region 139 of the disc body 133 to the edge of the disc body 133. Through the arrangement of the mounting member 125, the spreading motor 127 and the spreading disc 123 can be installed stably, and the middle region 139 of the spreading disc 123 can face the outlet 119, so that the material output from the outlet 119 can be spread along the plurality of paddles 135 under the driving of the spreading motor 127 and the centrifugal force generated by the rotation of the disc body 133 after reaching the middle region 139. By providing a plurality of paddles 135 , the material can be evenly dispersed in the circumference of the middle region 139 , so that all positions of the disc 133 can discharge the material evenly, thereby ensuring the uniformity of spreading, and ensuring the spreading effect and quality.

[0074] As an optional solution, in this embodiment, three paddles 135 are arranged at intervals on each disk body 133, and the three paddles 135 are evenly spaced and arranged at the circumferential edge of the middle area 139 of the disk body 133 to fully ensure the uniformity of spreading. Of course, in other embodiments, the number of paddles 135 on the disk body 133 can also be adjusted and selected according to needs, and this embodiment will not be repeated.

[0075] Further optionally, in the present embodiment, in the two spreading mechanisms 113 distributed on both sides of the material box 107, the rotation direction of the spreading motor 127 of each spreading mechanism 113 is the same, that is, the three spreading motors 127 of the same spreading mechanism 113 have the same rotation direction. At the same time, the rotation directions of the spreading motors 127 of the two spreading mechanisms 113 located on both sides of the material box 107 are opposite, that is, the rotation direction of the three spreading motors 127 of the spreading mechanism 113 on one side of the material box 107 is opposite to the rotation direction of the three spreading motors 127 of the spreading motor 127 on the other side of the material box 107. By setting the rotation directions of the spreading motors 127 located on one side of the material box 107 to be consistent and setting the rotation directions of the spreading motors 127 located on both sides of the material box 107 to be opposite, the spreading range of the spreading device 100 is wider, and the distribution of the material particles during spreading is more uniform, so that the spreading efficiency and quality can be fully guaranteed.

[0076] Furthermore, in this embodiment, each paddle 135 is provided with a bent portion 137 bent toward the front side of the rotation direction of the corresponding spreading motor 127 at one end away from the disc body 133. On the one hand, the material output from the middle area 139 to the position of the paddle 135 can be blocked by the setting of the bent portion 137 to prevent it from being thrown upward directly, so as to ensure that it can be spread along the extension direction of the paddle 135, thereby ensuring the spreading range and spreading uniformity, so as to improve the spreading quality and effect; on the other hand, since the rotation directions of the spreading motors 127 on both sides of the material box 107 are opposite, and the bending direction of the bent portion 137 of each paddle 135 is consistent with the rotation direction of the spreading motor 127 at the corresponding position, the bending directions of the paddles 135 on both sides of the material box 107 are opposite, thereby making the spreading range of the entire spreading device 100 wider, further ensuring the uniformity of particle distribution during spreading, and further improving the spreading efficiency and quality.

[0077] The following is a detailed description of the installation process, working principle and beneficial effects of the drone equipped with the spreading device 100 provided in the embodiment of the present invention:

[0078] When the drone is installed, the shell 115 of the spreading device 100 can be adjusted to the unfolded position relative to the base frame 101, and then the spreading device 100 can be installed on the fuselage. In the process of adjusting the position of the shell 115, the remote control device 177 can first send an unfolding signal to the main control board 179, so as to control the rotation of the rotating motor 156 of the spreading device 100 through the main control board 179, so as to drive the shell 115 and the conveying motor 145 to rotate relative to the base frame 101 at the same time. When the magnetic encoder 181 feedbacks that the rotation is in place, the main control board 179 can be used to control the rotating motor 156 to stop rotating.

[0079] When the UAV performs a spreading operation, the conveying motor 145 is engaged with the unloading auger 147, and the main control board 179 controls the conveying motor 145 to start to drive the unloading auger 147 to rotate. The material passes through the unloading port 111 of the material box 107 and is input from the inlet 117 of the shell 115, and is output to each outlet 119 driven by the unloading auger 147; the main control board 179 controls the spreading motor 127 to start and spread the material output from the outlet 119 to the middle area 139 of the disk 133.

[0080] When the spreading operation is completed and the spreading device 100 needs to be transported or stored, the spreading device 100 can be removed from the fuselage, and then a folding signal is sent to the main control board 179 through the remote control device 177 to control the rotating motor 156 to reverse through the main control board 179, so as to simultaneously drive the shell 115 and the conveying motor 145 to move to the folding position relative to the base frame 101. After the magnetic encoder 181 indicates that the folding position has been reached, the rotating motor 156 can be controlled to stop driving through the main control board 179.

[0081] In the above process, the sowing device 100 sets the shell 115 of the sowing mechanism 113 to be rotatable relative to the base frame 101, so that when the shell 115 is unfolded relative to the base frame 101, the sowing width of the sowing mechanism 113 can be guaranteed, and the sowing efficiency and quality can be guaranteed. When the shell 115 is folded relative to the base frame 101, the volume of the sowing mechanism 113 can be reduced, making the transportation and storage of the sowing mechanism 113 more convenient and reliable.

[0082] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
