At the same time, a feeding piece can also realize uniform delivery of materials to the two outlets, ensuring that the materials delivered to the two outlets are equal and uniform, thereby fully ensuring the uniformity of the feeding operation, fully ensuring the uniformity of the spreading operation, and thus improving the spreading quality. The structure of the drone is described in detail below.

[0046] Figure 1A structural schematic diagram of a spreading device 300 provided in this embodiment; Figure 2 A schematic diagram of the structure of the feeding device 200 provided in this embodiment; Figure 3 This is a partial exploded schematic diagram of the feeding device 200 provided in this embodiment. Figures 1 to 3 The drone provided in this embodiment includes a frame (not shown), a sowing device 300 and a material storage device (not shown).

[0047] In detail, the frame is the main structure of the entire UAV, which is used to install additional equipment such as the sowing equipment 300 and the material storage equipment for agricultural operations such as sowing, and is used to perform flight operations on the other hand to ensure the sowing needs of crops. Among them, the sowing equipment 300 is specifically installed on the frame, the material storage equipment is installed on the sowing equipment 300 or directly installed on the frame, and the material storage equipment is connected to the sowing equipment 300, which is used to transport fertilizers, seeds and other materials to the sowing equipment 300. After receiving the materials, the sowing equipment 300 performs sowing operations to complete the sowing task. Of course, in other embodiments, the UAV can also carry other equipment to perform operations, such as carrying a spray device to spray pesticides, etc.; at the same time, the sowing equipment 300 provided in this embodiment can also be carried on other structures for use, such as being carried on an unmanned vehicle or other movable equipment for use, and is not limited to UAVs, and will not be repeated in this embodiment.

[0048] Please refer again Figures 1 to 3 In this embodiment, the sowing device 300 specifically includes a feeding device 200 and two sowing devices 301. The feeding device 200 is provided with an inlet 206 and two outlets 211, and the material storage device can be directly fixedly connected to the sowing device 300, and the material storage device is connected to the inlet 206 for conveying materials to the inlet 206. The two outlets 211 are respectively connected to the two sowing devices 301, so that the materials input from the inlet 206 can be respectively conveyed from the outlets 211 to the corresponding sowing devices 301 for sowing operations. Of course, in other embodiments, the number of sowing devices 301 and the number of outlets 211 can also be adjusted according to demand, for example, it can be set to three sowing devices 301 and three outlets 211, or four sowing devices 301 and four outlets 211, or even more, which can effectively improve the sowing efficiency under the premise of ensuring the cost, and this embodiment is not limited.

[0049] In detail, in this embodiment, the feeding device 200 specifically includes a feeding shell 201 and a feeding member 213 .

[0050] The feeding housing 201 is a cylindrical hollow structure, and the feeding housing 201 has a feeding chamber 227, an inlet 206 and two outlets 211 are respectively opened on the side wall of the feeding housing 201, and are connected to the feeding chamber 227. Among them, the inlet 206 is used to communicate with the material storage device for material input, and the outlet 211 is used to output the material for the sowing device 301 at the corresponding position to perform sowing operations. Of course, in other embodiments, the shape of the feeding housing 201 can also be adjusted according to needs, for example, it can be set to a square shape, etc., as long as the feeding efficiency and quality can be guaranteed, and this embodiment does not limit it.

[0051] The feeding member 213 is a feeding auger, and the feeding member 213 specifically includes a feeding shaft 215 and blades spirally arranged on the circumference of the feeding shaft 215. The feeding shaft 215 is movably arranged in the feeding housing 201 and is located between the two outlets 211. At least part of the blade is opposite to the inlet 206 and is used to equally transport materials to the two outlets 211 when the feeding shaft 215 rotates. On the one hand, the feeding device 200 is arranged between the two outlets 211 through a feeding piece 213, which can realize two-way transportation of materials to the two outlets 211, can effectively simplify the feeding structure, improve feeding efficiency and quality, save feeding costs, and can also improve the problem of single feeding method in the prior art to meet the feeding needs of simultaneous discharge of materials from the two outlets 211, so that it can be suitable for the sowing operation with two sowing devices 301 to fully guarantee the sowing range of the entire sowing equipment 300; on the other hand, the blades can also transport materials to the two outlets 211 in equal amounts, so that the uniformity of the discharge of materials from the two outlets 211 is guaranteed, thereby fully guaranteeing the uniformity of the feeding of the entire feeding device 200, and then can improve the uniformity of the sowing operation, ensure the sowing quality, so that the sowing equipment 300 not only has the advantages of high feeding efficiency and quality, but also has the advantages of high sowing quality and efficiency.

[0052] In detail, in this embodiment, the structures of the two spreading devices 301 are completely the same, and each spreading device 301 includes a spreading housing 302, a spreading motor 303, and a spreading disc 305. The spreading housing 302 is fixedly or detachably connected to the feeding housing 201, and the spreading housing 302 has a spreading channel, which can be connected to the outlet 211 at the corresponding position. The spreading motor 303 is arranged in the spreading housing 302 and is transmission-connected to the spreading disc 305, and is used to drive the spreading disc 305 to rotate so as to spread the material output from the outlet 211. On the one hand, through the cooperation of a feeding piece 213, two outlets 211 and two sowing devices 301, the two sowing devices 301 can perform sowing operations at the same time. Compared with the prior art that one feeding piece 213 can only cooperate with one sowing device 301 for sowing operations, the sowing range is larger, and the sowing efficiency and quality are higher. Moreover, since one feeding piece 213 can feed materials to two sowing devices 301 at the same time, the structure is more compact and has lower cost, which is convenient for maintenance and use. On the other hand, since the blades can discharge equal amounts of materials to the two outlets 211, the materials output from the two outlets 211 to the two sowing devices 301 are equal and uniform, thereby fully ensuring the uniformity of sowing by the two sowing devices 301, thereby fully improving the uniformity of the sowing operation of the entire sowing equipment 300, and further ensuring the sowing efficiency and quality.

[0053] Please refer again Figures 1 to 3 In order to realize that a feeding member 213 can feed materials in equal amounts in both directions when rotating, in this embodiment, the feeding member 213 is configured as a bidirectional conveying auger, and the blades of the feeding member 213 specifically include a first blade 217 and a second blade 219 with opposite rotation directions. The first blade 217 and the second blade 219 are both spiral blades, and along the axial direction of the feeding shaft 215, the length, pitch and height of the first blade 217 and the second blade 219 are the same, and the length of the first blade 217 and the second blade 219 opposite to the inlet 206 is the same. On the one hand, the length, pitch and height of the first blade 217 and the second blade 219 are set to be the same, so that the amount of material that can be conveyed by the first blade 217 and the second blade 219 when rotating is uniform and the same, which can provide sufficient guarantee for conveying equal amounts of materials; on the other hand, since the lengths of the parts of the first blade 217 and the second blade 219 opposite to the inlet 206 are the same, the amount of material input from the inlet 206 to the first blade 217 and the second blade 219 is the same, which can further ensure that the amount of material conveyed to the two outlets 211 by the first blade 217 and the second blade 219 is equal when the feed shaft 215 rotates, thereby fully ensuring the uniformity of two-way feeding, and further ensuring the uniformity of the sowing operation, so as to fully improve the sowing efficiency and sowing quality.

[0054] In detail, in this embodiment, the feeding housing 201 specifically includes an inner housing 203 and an outer housing 205, the outer housing 205 is sleeved outside the inner housing 203, and one end of the inner housing 203 extends from the outer housing 205, a first inlet 207 is provided on the outer housing 205, and a second inlet 209 is provided at a corresponding position on the inner housing 203, and the first inlet 207 and the second inlet 209 together form an inlet 206 of the entire feeding housing 201. At the same time, two outlets 211 are respectively provided in the inner housing 203, and the feeding shaft 215 is specifically provided in the inner housing 203, extending between the two outlets 211, and one end is supported by the inner housing 203, and the other end is supported by the outer housing 205, so as to fully ensure the stability of its rotation, thereby improving the stability of feeding, so as to further ensure the uniformity of feeding, so as to improve the uniformity of spreading.

[0055] Figure 4 This is a schematic diagram of the structure of the first feeding member 213 of the feeding device 200 provided in this embodiment. Figure 4 In this embodiment, when the first blade 217 and the second blade 219 rotate in opposite directions, there are many ways to position and arrange the two blades, such as Figure 4 As shown, the first blade 217 has a first end 221 close to the second blade 219, and the second blade 219 has a second end 223 close to the first blade 217. The feed shaft 215 has a center line 226 (interval) with the inlet 206. Figure 2 ) is located at a middle position 225 (approximately located at the middle of the axial direction of the feed shaft 215). The first end 221 and the second end 223 both extend to the middle position 225 and are respectively located at two radial sides of the feed shaft 215. At this time, the first blade 217 and the second blade 219 are not symmetrical with respect to the radial plane where the middle position 225 is located. By extending the first blade 217 and the second blade 219 to the middle position 225 of the feed shaft 215, the circumferential space of the feed shaft 215 can be fully utilized, so that the length and size of the parts of the first blade 217 and the second blade 219 opposite to the inlet 206 are longer, so that the material input into the inlet 206 can fully act on the first blade 217 and the second blade 219, thereby facilitating the first blade 217 and the second blade 219 to evenly drive the material to move toward the two outlets 211, so as to transport the material from the two outlets 211 to the two spreading devices 301 in equal amounts and synchronously, so that the two spreading devices 301 can evenly perform the spreading operation, thereby further improving the spreading efficiency and the spreading quality.

[0056] Of course, in other embodiments, the first end 221 of the first blade 217 and the second end 223 of the second blade 219 may also be spaced apart at positions equidistant from the middle position 225, and do not necessarily have to extend to the middle position 225. As long as the lengths of the parts of the first blade 217 and the second blade 219 opposite to the inlet 206 are equal, this embodiment will not be repeated.

[0057] Figure 5 This is a schematic diagram of the structure of the second feeding member 213 of the feeding device 200 provided in this embodiment. Figure 5 When the first blade 217 and the second blade 219 are not symmetrically arranged relative to the radial plane where the middle position 225 is located, the first end 221 of the first blade 217 and the second end 223 of the second blade 219 can also be connected at the middle position 225. For example, when manufacturing the blade, the first blade 217 and the second blade 219 can be integrally formed or welded after the first blade 217 and the second blade 219 are respectively arranged. By connecting the first blade 217 and the second blade 219 to the first end 221 and the second end 223 close to each other, the overall strength of the blades in the circumferential direction of the entire feeding shaft 215 is fully improved, so as to facilitate the safety, stability and reliability of the material conveying process, and further ensure the stability and reliability of the sowing operation. At the same time, since there is no gap between the first blade 217 and the second blade 219, the material with high viscosity is not easy to be retained between the first blade 217 and the second blade 219, which can avoid material blockage and ensure the smoothness of the feeding operation and the sowing operation, so as to further improve the sowing efficiency and sowing quality.

[0058] Figure 6 This is a schematic diagram of the structure of the third feeding member 213 of the feeding device 200 provided in this embodiment. Figure 6 In this embodiment, the first blade 217 and the second blade 219 can also be symmetrically arranged with the radial plane where the middle position 225 is located as the symmetry plane. Figure 6As shown, when the first blade 217 and the second blade 219 are symmetrically arranged with the radial plane where the middle position 225 is located as the symmetry plane, the first end 221 of the first blade 217 and the second end 223 of the second blade 219 can also be connected and arranged at the middle position 225 to ensure the strength of the entire blade, thereby ensuring the stability and reliability of the entire feeding process, while avoiding material blockage. Of course, in other embodiments, when the first blade 217 and the second blade 219 are symmetrically arranged with the radial plane where the middle position 225 is located as the symmetry plane, the first end plate of the first blade 217 and the second end 223 of the second blade 219 can also be set to be at the same distance from the middle position 225, ensuring that the lengths and sizes of the parts of the first blade 217 and the second blade 219 relative to the inlet 206 are the same, and this embodiment will not be repeated. In addition, the first blade 217 and the second blade 219 are arranged to be symmetrical in the radial plane relative to the middle position 225, so that the force applied to the first blade 217 and the second blade 219 during the material conveying process is more uniform, and the force applied to the feed shaft 215 by the first blade 217 and the second blade 219 is more uniform, thereby further ensuring the stability of the operation of the feed shaft 215, thereby improving the stability and reliability of the feeding and material spreading operations, and further extending the service life of the feed shaft 215, thereby reducing the use and maintenance costs.

[0059] pass Figures 4 to 6 It can be seen from the comparison that in this embodiment, when the first blade 217 and the second blade 219 rotate in opposite directions, the first blade 217 and the second blade 219 can be symmetrically arranged on the radial plane where the middle position 225 is located, or can be asymmetrically arranged. At the same time, the first end 221 of the first blade 217 and the second end 223 of the second blade 219 can be arranged at the same distance from the middle position 225, or can be directly extended to the middle position 225 and located on both sides of the radial direction of the feeding shaft 215, or can be directly extended to the middle position 225 and connected. Regardless of which solution is adopted, as long as the lengths of the first blade 217 and the second blade 219 opposite to the inlet 206 are the same, it can be ensured that the first blade 217 and the second blade 219 can transport materials to the two outlets 211 in equal amounts, thereby ensuring the uniformity of the materials spread by the two spreading devices 301, so as to fully improve the spreading quality and spreading efficiency of the spreading equipment 300.

[0060] Please refer again Figures 4 to 6Regardless of how the positions of the first blade 217 and the second blade 219 are arranged, in the present embodiment, the feed shaft 215 can be arranged to be coaxial with the feed chamber 227 of the feed shell. By arranging the feed shaft 215 to be coaxial with the feed chamber 227, the stability and smoothness of the feed shaft 215 during rotation are higher. At the same time, when the feed shaft 215 rotates, the first blade 217 and the second blade 219 drive the material to move more evenly, thereby further ensuring that equal amounts of material are delivered to the two outlets 211, so as to improve the uniformity of material delivery and spreading.

[0061] In detail, in order to facilitate the arrangement of the feed shaft 215, in this embodiment, the first inlet 207 can be directly opened in the circumference of the outer shell 205, and the second inlet 209 can be opened in the circumference of the inner shell 203, so that the first inlet 207 and the second inlet 209 can jointly form an inlet 206 opened in the circumference of the feed shell 201. At the same time, the two outlets 211 are respectively opened at both ends of the inner shell 203, so that the feed shaft 215 can be extended along the axis of the feed shell 201 and arranged between the two outlets 211, which is not only convenient for improving the stability of the feed shaft 215, but also conducive to ensuring that the first blade 217 and the second blade 219 can drive the same amount of material movement during the rotation of the feed shaft 215. In addition, it should be noted that in this embodiment, the height of the first blade 217 and the second blade 219 can be set to match the radius of the feeding chamber 227 or be slightly smaller than the radius, so that the first blade 217 and the second blade 219 can drive the movement of materials at various positions in the feeding chamber 227 during rotation, so as to further ensure the uniformity of material transportation and material spreading.

[0062] As an optional solution, in this embodiment, the distances between the two sides of the inlet 206 and the two ends of the feeding housing 201 are the same. The distances between the inlet 206 and the two ends of the feeding housing 201 are made the same, so that the distances between the inlet 206 and the two outlets 211 are the same, so that when the feeding shaft 215 rotates to drive the first blade 217 and the second blade 219 to rotate synchronously, the materials driven by the first blade 217 and the second blade 219 can move synchronously and equally to the two outlets 211, and the two outlets 211 can synchronously and equally transport materials to the two sowing devices 301, so that the two sowing devices 301 can also sow materials synchronously and equally, and further improve the uniformity and synchronization of the sowing operation, and ensure the sowing quality and sowing effect.

[0063] Please refer again Figures 1 to 3 Regardless of the structure of the feeding member 213, in this embodiment, the feeding member 213 can be mechanically driven to rotate by a driving member to fully ensure the feeding and spreading efficiency.

[0064] In detail, in this embodiment, the driving member specifically includes a driving motor 229 and a mounting shell 231. The driving motor 229 is mounted on the end of the feeding housing 201 through the mounting shell 231, and is specifically fixedly connected to the housing 205 and is arranged at the end of the housing 205. The output shaft of the driving motor 229 is coaxially connected to the feeding shaft 215 through the transmission member 230, and the transmission member 230 is a transmission shaft, so that when the driving motor 229 is running, the power of the driving motor 229 can be transmitted to the feeding shaft 215 to drive the feeding shaft 215 to rotate, so that the first blade 217 and the second blade 219 can drive the material to move to the two outlets 211 in an equal amount and synchronously, so as to ensure the uniformity of the feeding operation and the material spreading operation, so as to improve the spreading efficiency and the spreading quality.

[0065] It should be noted that in other embodiments, in order to ensure that the power of the driving motor 229 can be better transmitted to the feeding shaft 215, a reducer or other structure can be added between the feeding shaft 215 and the driving motor 229, or power can be transmitted through a gear set or gear pair, which will not be repeated in this embodiment.

[0066] Figure 7 A schematic diagram of the structure of another spreading device provided in this embodiment; Figure 8 This is an exploded schematic diagram of another spreading device provided in this embodiment. Figure 7 and Figure 8 This embodiment also provides another spreading device 300, in which the feeding housing 201 of the feeding device 200 includes an outer shell 205 and two inner shells 203 partially embedded in the outer shell 205, each inner shell 203 is provided with a feeding chamber 227, and the inlet 206 of the feeding housing 201 is opened at the top of the outer shell 205, and includes a first inlet 207 and a second inlet 209 respectively connected to the two feeding chambers 227. At the same time, two outlets 211 are respectively opened at the ends of the two inner shells 203, and are connected to the two feeding chambers 227 in a one-to-one correspondence.

[0067] Correspondingly, the feeding member 213 includes two parallel and spaced feeding shafts 215, each of which is provided with a blade with a rotation direction. For example, one feeding shaft 215 is provided with a first blade 217, and the other feeding shaft 215 is provided with a second blade 219. The rotation directions of the two can be opposite or the same. Furthermore, the spiral length, pitch and height of the first blade 217 and the second blade 219 outside the two feeding shafts 215 are the same, and the length of each first blade 217 relative to the first inlet 207 is the same as the length of the portion of the second blade 219 relative to the second inlet 209, so that one feeding piece 213 can also convey materials to the two outlets 211 at the same time, and the first blade 217 and the second blade 219 can also convey materials to the two outlets 211 in equal amounts, thereby ensuring the uniformity of the discharge of materials from the two outlets 211, and further ensuring the uniformity of the feeding of the entire feeding device 200, so that the feeding device 200 can effectively improve the feeding efficiency and feeding quality while fully ensuring the uniformity of the feeding operation, and correspondingly ensure the sowing uniformity to improve the sowing quality.

[0068] For details, please refer again Figure 7 and Figure 8 In order to drive the two feeding shafts 215 to move at the same time, in this embodiment, the driving member can be specifically configured to include a driving motor 229 and a transmission assembly. The feeding housing 201 forms a motor cavity 319 between the two feeding chambers 227. The driving motor 229 is disposed in the motor cavity 319 and is shielded by a motor cover 309 disposed outside the motor cavity 319. The feeding housing 201 is provided with a gear cavity (not shown) at the end near the driving motor 229. The outer cover of the gear cavity is provided with an end cover 311, and the transmission assembly is disposed in the gear cavity. The transmission assembly specifically includes a first gear 313, a second gear 315 and a third gear 317 which are meshed in sequence. The second gear 315 is located between the first gear 313 and the third gear 317. The second gear 315 is connected to the drive motor 229. The first gear 313 and the third gear 317 are connected to the two feeding shafts 215 respectively, so that when the drive motor 229 drives the second gear 315 to rotate, the first gear 313 and the third gear 317 on both sides can be driven to drive the two feeding shafts 215 to rotate, so as to drive the first blade 217 and the second blade 219 to transport materials to the two outlets 211 in equal amounts, so that the two sowing devices 301 at the corresponding positions can perform sowing operations in equal amounts, so as to effectively ensure the sowing efficiency and quality.

[0069] At the same time, compared with the solution of using two drive motors 229 to drive the two feeding shafts 215 to move simultaneously, this embodiment uses one drive motor 229 to drive the two feeding shafts 215 to move simultaneously, thereby further improving the feeding efficiency and quality, so as to further improve the sowing efficiency and quality.

[0070] Taking the structure of the first spreading device 300 as an example, the installation process, working principle and beneficial effects of the drone provided by the embodiment of the present invention are described in detail below:

[0071] When the UAV is installed, the two assembled spreading devices 301 can be installed at the two ends of the assembled feeding device 200, and connected to the two outlets 211 at the two ends of the feeding device 200 to form a spreading device 300; then, the spreading device 300 is installed on the frame of the UAV, and the storage device is installed on the upper end of the spreading device 300, and connected to the spreading device 300 through the inlet 206. In the process of assembling the feeding device 200, the inner shell 203 can be placed in the outer shell 205, and then the feeding shaft 215 can be placed inside the inner shell 203, and the lengths of the first blade 217 and the second blade 219 relative to the inlet 206 are the same, and then the driving motor 229 is installed on the outer shell 205 through the mounting shell 231, and the feeding shaft 215 and the driving motor 229 are matched through the transmission member 230.

[0072] When the UAV performs a spreading operation, it can fly to the destination and then start the drive motor 229 to drive the feed shaft 215 to rotate. Since the first blade 217 and the second blade 219 are exactly the same, and the distance between the inlet 206 and the two outlets 211 is the same, the lengths and sizes of the first blade 217 and the second blade 219 relative to the inlet 206 are exactly the same, so the first blade 217 and the second blade 219 can drive the material input from the inlet 206 to move toward the two outlets 211 in an equal amount and synchronously, so that the two outlets 211 can transport the material to the two spreading devices 301 in an equal amount and synchronously, thereby facilitating the two spreading devices 301 to perform material spreading operations in an equal amount and synchronously.

[0073] In the above process, on the one hand, the feeding device 200 is arranged between the two outlets 211 through a feeding piece 213, which can realize bidirectional transportation of materials. Compared with the use of two feeding pieces 213 to realize bidirectional feeding, it can effectively simplify the feeding structure, improve feeding efficiency and quality, and save feeding costs. Moreover, discharging materials through the two outlets 211 can also improve the problem of single feeding method in the prior art, so as to meet the feeding demand of discharging materials from the two outlets 211 at the same time, so that it can be applied to the sowing operation with two sowing devices 301 to fully guarantee the sowing range of the entire sowing equipment 300; on the other hand, the blades can also convey materials to the two outlets 211 in equal amounts, so that the uniformity of the discharge of materials from the two outlets 211 is guaranteed, thereby fully guaranteeing the uniformity of the feeding of the entire feeding device 200, and then improving the uniformity of the sowing operation, ensuring the sowing quality, so that the sowing equipment 300 not only has the advantages of high feeding efficiency and quality, but also has the advantages of high sowing quality and efficiency.

[0074] In summary, the embodiments of the present invention provide a feeding device 200, a spreading device 300 and a drone with high feeding efficiency and quality, low cost, high feeding and spreading uniformity and stability, and high spreading efficiency and quality.

[0075] 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.
