DETAILED DESCRIPTION

[0038] 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.

[0039] 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.

[0040] 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, further definition and explanation thereof is not required in subsequent drawings.

[0041] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of the invention is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0044] When the aircraft is performing a spreading operation, different augers are required to spread different granular materials. For example, different augers have spiral blades with different diameters. At the same time, the radial heights of the spiral blades of different augers may also be different. The spreading device in the prior art needs to be equipped with different augers, which will increase the cost to a certain extent, and the user needs to disassemble and assemble it when using it, which requires certain operating difficulties.

[0045] Specifically, if materials of different diameters need to be spread, the spinner connecting rod box assembly needs to be removed, and the auger can be removed after the material discharging fixed cover is installed. Then, the auger suitable for the corresponding diameter needs to be replaced for spreading operations. This operation is inconvenient and difficult.

[0046] In view of this, please refer to Figure 1-Figure 9 The spreading device 1000 and the drone provided in the embodiments of the present invention can solve this problem, which will be described in detail below.

[0047] Please refer to Figure 1 In an embodiment of the present invention, a drone is provided, which includes a sowing device 1000. The sowing device 1000 can be used to sow particles such as seeds, powders, and solid fertilizers. The sowing device 1000 can be suitable for sowing different granular materials without replacing the feeding auger 210, which facilitates the sowing operation and reduces costs.

[0048] The drone mentioned here can be understood as an agricultural drone, which can be a twin-rotor drone, a single-rotor drone or a multi-rotor drone, such as a quad-rotor drone, a six-rotor drone, an eight-rotor drone, etc.

[0049] The drone can operate automatically according to a preset path, flight speed, attitude, etc., or it can be manually controlled by the operator.

[0050] Please continue to refer to Figure 2 Combined with Figure 1 Specifically, the sowing device 1000 includes a storage box 100 and a feeding mechanism 200. The storage box 100 can store materials such as seeds, powders, solid fertilizers, etc. The storage box 100 has a feeding port 101. The feeding mechanism 200 includes a feeding shell 220 and a feeding auger 210 rotatably installed in the feeding shell 220. The feeding auger 210 has a plurality of spiral sections 211, and the discharge flow rates corresponding to at least any two of the plurality of spiral sections 211 are different.

[0051] Among them, when the sowing device 1000 is working, the feed port 101 is only set to correspond to one of the multiple spiral sections 211, so that the material in the storage box 100 can only fall into the spiral section 211 corresponding to the feed port 101. Since the feeding auger 210 has spiral sections 211 with different discharge flow rates, when the sowing device 1000 is working, according to different particulate materials, the feed port 101 corresponds to the spiral section 211 with the required discharge flow rate, and there is no need to replace the feeding auger 210, which facilitates the sowing operation and reduces the cost.

[0052] In addition, in this embodiment, please refer to Figure 1 The spreading device 1000 further includes a spreading mechanism 1100 , which is installed on the material feeding housing 220 , and is used to spread the material in the material feeding housing 220 .

[0053] Specifically, the spreading device 1000 includes a spinner motor, a connecting rod mechanism and a spinner that are connected in sequence. The spinner motor can be installed in the feed shell 220. The spinner motor drives the connecting rod mechanism to move to cause the spinner to swing. During the rotation of the feed auger 210, the material in the feed shell 220 can be transported to the spinner position. The spinner can spread the material in the feed shell 220, thereby realizing the material spreading function of the spreading device 1000.

[0054] It should be noted that in order to facilitate the material conveying function of the feed auger 210, the feed mechanism 200 also includes a driving member 300. The driving member 300 can be a motor. The driving member 300 is connected to the feed auger 210. The driving member 300 is used to drive the feed auger 210 to rotate so as to convey the material in the feed shell 220 to the spinner position.

[0055] It should be noted that the "multiple" mentioned in the present application can be understood as "at least two", that is, the spiral section 211 of the feed auger 210 can be two. At this time, the discharge flow rates corresponding to the two spiral areas are different, so as to adapt to different granular materials, such as granular materials of different diameters.

[0056] Of course, the number of spiral sections 211 of the feed auger 210 may also be three, four, five or six, etc. For example, when the number of spiral sections 211 of the feed auger 210 is four, there may be two spiral sections 211 with the same discharge flow rate, and the remaining two spiral sections 211 may be different. At the same time, a spiral section 211 with a larger or smaller discharge flow rate may be distributed between the two spiral sections 211 with the same discharge flow rate.

[0057] Of course, when there are four spiral sections 211 of the feeding auger 210, the discharge flow rates of any two of the four spiral sections 211 may be different.

[0058] It is easy to understand that each spiral segment 211 includes a rotating shaft and blades. The blades can be spirally wound around the rotating shaft. The rotating shafts of adjacent spiral segments 211 can be connected. At the same time, the blades of adjacent spiral segments 211 can also be connected. The rotating shaft of one spiral segment 211 is connected to a drive.

[0059] Specifically, the blade pitches corresponding to at least any two of the multiple spiral segments 211 are different, and the radial heights of the blades corresponding to any two of the multiple spiral segments 211 are the same, so that the discharge flow rates corresponding to at least any two of the multiple spiral segments 211 are different. The larger the blade pitch, the greater the discharge flow rate of the spiral segment 211.

[0060] Here, the radial height of the blade can be understood as the distance from the outer wall of the rotating shaft of each spiral section 211 of the feeding auger 210 to the highest point of the blade of the corresponding spiral section 211 along the radial direction of the feeding auger 210 .

[0061] For example, when there are two spiral segments 211 , the pitches of the blades corresponding to the two spiral segments 211 are different, and at the same time, the radial heights of the blades corresponding to the two spiral segments 211 are the same.

[0062] For another example, when there are three spiral segments 211, the corresponding blade pitches of two spiral segments 211 may be the same, and the corresponding blade pitch of another spiral segment 211 may be different from the corresponding blade pitches of the remaining two spiral segments 211. Meanwhile, the corresponding blades of the three spiral segments 211 have the same radial height.

[0063] Of course, it is also possible that, when the number of the spiral sections 211 is three, the corresponding blade pitches of the three spiral sections 211 are different, and at the same time, the radial heights of the corresponding blades of the three spiral sections 211 are the same.

[0064] Alternatively, the radial heights of the blades corresponding to at least any two of the multiple spiral segments 211 are different, and the pitches of the blades corresponding to any two of the multiple spiral segments 211 are the same, so that the discharge flow rates corresponding to at least any two of the multiple spiral segments 211 are different, and the larger the radial height of the blade, the larger the discharge flow rate of the spiral segment 211.

[0065] For example, when there are two spiral segments 211 , the radial heights of the corresponding blades of the two spiral segments 211 and the pitches of the corresponding blades of the two spiral segments 211 are the same.

[0066] For another example, when there are three spiral segments 211, the radial heights of the corresponding blades of two spiral segments 211 may be the same, and the radial height of the corresponding blade of another spiral segment 211 may be different from the radial heights of the corresponding blades of the remaining two spiral segments 211. At the same time, the corresponding blades of the three spiral segments 211 have the same pitch.

[0067] Of course, it is also possible that, when the number of the spiral sections 211 is three, the radial heights of the corresponding blades of the three spiral sections 211 and the corresponding blade pitches of the three spiral sections 211 are the same.

[0068] In addition, the blade pitches corresponding to at least any two of the multiple spiral segments 211 may be different, and the radial heights of the blades corresponding to at least any two of the multiple spiral segments 211 may be different, so that the discharge flow rates corresponding to at least any two of the multiple spiral segments 211 are different.

[0069] For example, when the number of spiral segments 211 is two, the blade pitches corresponding to the two spiral segments 211 are different. At the same time, the radial heights of the blades corresponding to the two spiral segments 211 are different. The radial height of the blade corresponding to the spiral segment 211 with a larger blade pitch is also larger, or the radial height of the blade corresponding to the spiral segment 211 with a larger blade pitch is also smaller.

[0070] For another example, when there are three spiral segments 211 , the corresponding blade pitches of two spiral segments 211 may be the same, while the corresponding blade pitch of another spiral segment 211 may be different from the corresponding blade pitches of the remaining two spiral segments 211 .

[0071] Meanwhile, among the three spiral segments 211 , the radial heights of the corresponding blades of two spiral segments 211 may be the same, while the radial height of the corresponding blade of another spiral segment 211 may be different from the radial heights of the corresponding blades of the remaining two spiral segments 211 .

[0072] Of course, it is also possible that, when the number of spiral sections 211 is three, the corresponding blade pitches of the three spiral sections 211 are different, and at the same time, the radial heights of the corresponding blades of the three spiral sections 211 are the same, which can be specifically set according to the actual material flow requirements, and will not be repeated here.

[0073] In order to accommodate different sizes of discharge flow rates and avoid material jamming, the discharge flow rates corresponding to the plurality of spiral sections 211 are gradually increased along the conveying direction of the conveying auger.

[0074] Specifically, along the conveying direction of the conveying auger, the blade pitches corresponding to the plurality of spiral sections 211 may be gradually increased.

[0075] Alternatively, along the conveying direction of the conveying auger, the radial heights of the blades corresponding to the plurality of spiral sections 211 may be gradually increased.

[0076] Alternatively, along the conveying direction of the conveying auger, the pitch of the blades corresponding to the plurality of spiral sections 211 gradually increases, and at the same time, the radial height of the blades corresponding to the plurality of spiral sections 211 gradually increases.

[0077] Please refer to Figure 2 In the present embodiment, the feed auger 210 has three spiral sections 211, the rotating shafts of the three spiral sections 211 are connected in sequence, and the blades of the three spiral sections 211 are also connected in sequence. The pitches of the blades corresponding to any two of the three spiral sections 211 are different, and the radial heights of the blades corresponding to any two of the three spiral sections 211 are also different.

[0078] It can be understood that the feed auger 210 in this embodiment has a first spiral section 211, a second spiral section 211 and a third spiral section 211, the material flow corresponding to the first spiral section 211 is the smallest, the material flow corresponding to the third spiral section 211 is the largest, the material flow corresponding to the second spiral section 211 is between the material flow corresponding to the first spiral section 211 and the material flow corresponding to the third spiral section 211, and the rotating shaft of the first spiral section 211 can be connected to the driving member 300.

[0079] Among them, the blade pitch of the first spiral section 211 is smaller than the blade pitch of the second spiral section 211, and the radial height of the blades of the first spiral section 211 is smaller than the radial height of the blades of the second spiral section 211. At the same time, the blade pitch of the third spiral section 211 is greater than the blade pitch of the second spiral section 211, and the radial height of the blades of the third spiral section 211 is greater than the radial height of the blades of the second spiral section 211.

[0080] That is to say, the feeding auger 210 can realize material conveying of three different material flow rates. Meanwhile, along the conveying direction of the feeding auger, the discharge flow rates corresponding to the first spiral section 211, the second spiral section 211 and the third spiral section 211 gradually increase.

[0081] Please refer to Figure 3In order to facilitate the feeding port 101 to correspond to the spiral section 211 of the required discharge flow rate, the storage box 100 includes a box body 120 and a material blocking member 110. The box body 120 can be installed on the fuselage of the drone. At the same time, the box body 120 can be connected to the feeding shell 220. The box body 120 has a discharge port, and the material blocking member 110 is connected to the box body 120. The material blocking member 110 is used to block a part of the discharge port, so that the unblocked area forms the feeding port 101.

[0082] Specifically, the material blocking member 110 can be a plate structure, and the material blocking member 110 can block the spiral section 211 that does not need to feed. The material blocking member 110 can be installed obliquely in the box body 120. Since the material blocking member 110 is in an inclined state, it can prevent materials from accumulating on the material blocking member 110.

[0083] Of course, in some embodiments, the material blocking member 110 may also be horizontally installed in the box body 120. In this case, the material blocking member 110 is located in a horizontal plane.

[0084] It should be noted that the material blocking member 110 is detachably arranged in the box body 120. By adjusting the position of the material blocking member 110 in the box body 120, the material blocking member 110 can block different partial areas of the feed port, so that the feed port 101 just corresponds to the spiral section 211 of the required material flow.

[0085] There may be multiple material blocking members 110 , and at least one of the multiple material blocking members 110 is used to block a partial area of ​​the feed opening, so that the unblocked area forms the feed opening 101 .

[0086] In this embodiment, there may be two material blocking members 110 , which are spaced apart from each other. The area between the lower edges of the two material blocking members 110 may just correspond to the spiral section 211 of the required material flow rate, so that the feed port 101 only corresponds to the second spiral section 211 .

[0087] Specific as Figure 3 As shown, the material blocking member 110 on the left side blocks the first spiral section 211 , and the material blocking member 110 on the right side can block the third spiral section 211 , so that the feeding port 101 only corresponds to the second spiral section 211 .

[0088] Of course, please refer to Figure 1 When the spreading device 1000 has two material blocking members 110 in a plate structure, only one of them can be used and placed in the box 120, so that the material blocking member can block the second spiral section 211 and the third spiral section 211 at the same time, so that the spreading device 1000 can correspond the material flow rate of the first spiral section 211.

[0089] Alternatively, in some embodiments, the spreading device 1000 has only one material blocking member 110 in a plate structure, and the conveying auger has only two spiral sections 211 with different material flow rates. The material blocking member 110 blocks the spiral sections 211 with one material flow rate, so that the feeding port 101 only corresponds to the other spiral section 211.

[0090] Of course, in some embodiments, the number of material blocking members 110 may be three, four, or five, etc. For example, the spreading device 1000 has three material blocking members 110, and the conveying auger has four spiral sections 211 with different material flow rates. The three material blocking members 110 block any three of the spiral sections 211 with different material flow rates, so that the feeding port 101 corresponds to only one spiral section 211.

[0091] Alternatively, when the spreading device 1000 has three material blocking members 110, only two of the material blocking members 110 may be used, and the conveying auger has four spiral sections 211 with different material flow rates, one of the material blocking members 110 blocks one of the spiral sections 211, and the other material blocking member 110 blocks two spiral sections 211 at the same time, so that the feeding port 101 only corresponds to one spiral section 211.

[0092] In order to facilitate the detachable installation of the material blocking member 110 in the box body 120, please refer to Figure 4 The material storage box 100 in this embodiment further includes a support member 130 , and there may be multiple support members 130 . The multiple support members 130 are arranged in the box body 120 , and the support members 130 are used to support the material blocking member 110 .

[0093] Multiple support members 130 can support the lower edge and side walls of the material blocking member 110 to maintain the position of the material blocking member 110 in the box body 120. The distribution position and number of support members 130 can be set according to the required position of the material blocking member 110 in the box body 120, which will not be repeated here.

[0094] Please refer to Figure 5 In some embodiments, the material blocking member 110 can be a winding member, that is, the material blocking member 110 can be rolled up or unrolled, such as a rollable or unrollable cloth, one end of the material blocking member 110 is connected to the box body 120, and the other end of the material blocking member 110 can be rolled relative to the box body 120.

[0095] The other end of the material blocking member 110 is used to block a portion of the feed opening in the unfolded state (equivalent to the unwinding state), so that the unblocked area forms the feed opening 101.

[0096] Specifically, in this embodiment, one end of the material blocking member 110 has a hook, which is connected to the box body 120 through the hook, and the other end of the material blocking member 110 also has a hook, which is connected to the conveying shell at different positions through the hook, thereby achieving blocking of different spiral sections 211, so that the feeding port 101 corresponds to the spiral section 211 that just corresponds to the required material flow rate.

[0097] The number of the material blocking member 110 in the form of a winding member may be one, or the number of the material blocking member 110 in the form of a winding member may be multiple. At least one of the multiple material blocking members 110 is used to block a partial area of ​​the feed port, so that the unblocked area forms the feed port 101. It is easy to understand that the function of the material blocking member 110 in the form of a winding member in the unwinding state is equivalent to the above-mentioned material blocking member 110 in the form of a plate structure. When the spreading device 1000 has one material blocking member 110 in the form of a winding member or has multiple material blocking members 110 in the form of a winding member, the arrangement of the material blocking member 110 can refer to the relevant content of the above-mentioned material blocking member 110 in the form of a plate structure, which will not be repeated here.

[0098] In addition, in some embodiments, the material blocking member 110 may also be a folding member, that is, the material blocking member 110 may be extended or folded, and the material blocking member 110 may be equivalent to a plate structure when in the extended state.

[0099] One end of the material blocking member 110 is connected to the box body 120, and the other end of the material blocking member 110 is foldable relative to the box body 120. The other end of the material blocking member 110 is used to block a part of the discharge port in the unfolded state, so that the unblocked area forms the feeding port 101.

[0100] The number of the material blocking members 110 in the form of folding members may be one, or the number of the material blocking members 110 in the form of folding members may be multiple. At least one of the multiple material blocking members 110 is used to block a partial area of ​​the feed port, so that the unblocked area forms the feed port 101. It is easy to understand that the function of the material blocking member 110 in the form of a folding member in the unwinding state is equivalent to the above-mentioned material blocking member 110 in the form of a plate structure. When the spreading device 1000 has one material blocking member 110 in the form of a folding member or has multiple material blocking members 110 in the form of a folding member, the arrangement of the material blocking member 110 can refer to the relevant content of the above-mentioned material blocking member 110 in the form of a plate structure, which will not be repeated here.

[0101] Please refer to Figure 7-Figure 9The material storage box 100 includes a box body 120 and a material blocking member 110, the material blocking member 110 is connected to the box body 120, and the box body 120 can be installed on the fuselage of the drone. The material blocking member 110 here can be understood as a cylindrical structure, the upper port of the material blocking member 110 is connected to the box body 120, and the lower end of the material blocking member 110 is formed with a feeding port 101 connected to the upper port, and the material blocking member 110 can be deformed so that at least one of the position and size of the feeding port 101 can be adjusted to adapt to one of the multiple spiral sections 211.

[0102] The feeding port 101 may be connected to the feeding housing 220 , or the feeding housing 220 may be installed on the fuselage of the UAV.

[0103] For example, the material blocking member 110 may be made of an elastic material, such as elastic fabric, so that the material blocking member 110 can be deformed to change the position of the feeding port 101 to correspond to the spiral sections 211 at different positions.

[0104] Alternatively, the material blocking member 110 is deformed to change the size of the feeding port 101 so as to correspond to spiral sections 211 of different sizes.

[0105] Of course, according to actual conditions, the material blocking member 110 may be deformed and the position and size of the feeding port 101 may be adjusted to fit one of the multiple spiral sections 211 .

[0106] In this embodiment, the material blocking member 110 includes a connected annular frame and a cylindrical elastic fabric member, the elastic fabric member is connected to the box body 120, the annular frame can be a rectangular frame, the annular frame is used to define the feeding port 101, in order to facilitate the adjustment of the size of the feeding port 101, the part of the rod frame of the annular frame along the material conveying direction of the feeding auger 210 can be telescopic, and at the same time, the annular frame can be detachably connected to the feeding shell 220 through a snap-on structure, so as to selectively adapt to one of the three spiral sections 211.

[0107] For example, Figure 7 In the embodiment, the annular frame can be connected to the feeding housing 220 so that the feeding port 101 only corresponds to the second spiral section 211 . At this time, the material in the storage box 100 can only fall into the second spiral section 211 .

[0108] For example, Figure 8 In the embodiment, the annular frame can be connected to the feeding housing 220 so that the feeding port 101 only corresponds to the first spiral section 211 . At this time, the material in the storage box 100 can only fall into the first spiral section 211 .

[0109] For example, Fig. 9In the embodiment, the annular frame can be connected to the feeding housing 220 so that the feeding port 101 only corresponds to the third spiral section 211 . At this time, the material in the storage box 100 can only fall into the third spiral section 211 .

[0110] It should be noted that, in some embodiments, there are multiple storage boxes 100, and the feeding ports 101 of the multiple storage boxes 100 are used to selectively correspond to one of the multiple spiral sections 211. Generally speaking, the number of storage boxes 100 and the number of spiral sections 211 can be the same, or, when the multiple spiral sections 211 of the feeding auger 210 have at least two spiral sections 211 with the same discharge flow rate, the number of storage boxes 100 can be less than the number of spiral sections 211, so that one storage box 100 can match the spiral sections 211 with the same discharge flow rate.

[0111] That is to say, by preparing multiple storage boxes 100 with different sizes or positions of feed ports 101, when the sowing device 1000 is working, the feed port 101 of the storage box 100 can correspond to the spiral section 211 of the required discharge flow rate according to different particulate materials, and there is no need to replace the feed auger 210, which facilitates the sowing operation and reduces costs.

[0112] To summarize, the spreading device 1000 includes a storage box 100 and a feeding mechanism 200, the storage box 100 has a feeding port 101, the feeding mechanism 200 includes a feeding shell 220 and a feeding auger 210 rotatably mounted in the feeding shell 220, the feeding auger 210 has a plurality of spiral sections 211, and the discharge flow rates corresponding to at least any two of the plurality of spiral sections 211 are different, wherein when the spreading device 1000 is working, the feeding port 101 is only arranged to correspond to one of the plurality of spiral sections 211, so that the material can only fall into the spiral section 211 corresponding to the feeding port 101.

[0113] Since the feeding auger 210 has spiral sections 211 with different discharge flow rates, when the spreading device 1000 is working, the feeding port 101 is made to correspond to the spiral section 211 with the required discharge flow rate according to different particulate materials. There is no need to replace the feeding auger 210, which facilitates the spreading operation and reduces costs.

[0114] The drone includes the above-mentioned spreading device 1000 , and the drone has all the functions of the above-mentioned spreading device 1000 .

[0115] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
