[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[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 claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall 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, it does not need to be further defined or explained 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 accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. 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. Therefore, it 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 and describe, 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 can 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, the spiral blades of different augers have 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 operational 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 discharge fixing cover is installed. Then, the auger suitable for the corresponding diameter needs to be replaced for spreading operations. The operation is inconvenient and difficult.

[0046] In view of this, please refer to Figures 1-9 The spreading device 1000 and the drone provided in the embodiment 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 utility model, a drone is provided, which includes a sowing device 1000. The sowing device 1000 can 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, and solid fertilizers. 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 multiple spiral sections 211, and the discharge flow rates corresponding to at least any two of the multiple 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, the feed port 101 corresponds to the spiral section 211 with the required discharge flow rate according to different granular materials, and there is no need to replace the feeding auger 210, which makes the sowing operation convenient and reduces costs.

[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 feeding housing 220 , and is used to spread the material in the feeding housing 220 .

[0053] Specifically, the spreading device 1000 includes a disc motor, a connecting rod mechanism and a disc that are connected in sequence. The disc motor can be installed in the feed shell 220. The disc motor drives the connecting rod mechanism to move to drive the disc to swing. During the rotation of the feed auger 210, the material in the feed shell 220 can be transported to the disc position. The disc can spread the material in the feed shell 220 to realize 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 feeding auger 210, the feeding mechanism 200 also includes a driving member 300. The driving member 300 can be a motor. The driving member 300 is connected to the feeding auger 210. The driving member 300 is used to drive the feeding auger 210 to rotate so as to transport the material in the feeding shell 220 to the spinner position.

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

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

[0057] Of course, when the number of spiral sections 211 of the feeding auger 210 is four, 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 may be understood as the distance from the outer wall of the rotating shaft of each spiral section 211 of the conveying auger 210 to the highest point of the blade of the corresponding spiral section 211 along the radial direction of the conveying 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 blade pitches of two spiral segments 211 may be the same, while the blade pitch of another spiral segment 211 may be different from the blade pitches of the remaining two spiral segments 211. Furthermore, the blades of the three spiral segments 211 may have the same radial height.

[0063] Of course, it is also possible that, when there are three spiral segments 211 , the pitches of the blades corresponding to the three spiral segments 211 are different, and at the same time, the radial heights of the blades corresponding to the three spiral segments 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 greater the radial height of the blade, the greater 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 blades corresponding to two of the spiral segments 211 may be the same, while the radial height of the blades corresponding to another spiral segment 211 may be different from the radial heights of the blades corresponding to the remaining two spiral segments 211. Furthermore, the pitches of the blades corresponding to the three spiral segments 211 may be the same.

[0067] Of course, it is also possible that, when there are three spiral segments 211 , the radial heights of the blades corresponding to the three spiral segments 211 are the same, and at the same time, the pitches of the blades corresponding to the three spiral segments 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 at the same time, 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 there are two spiral segments 211, 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 blades 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. The specific setting can be made according to the actual material flow requirements, which 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 multiple spiral sections 211 gradually increase along the conveying direction of the feed 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 pitches of the blades corresponding to the plurality of spiral sections 211 gradually increase, and at the same time, the radial heights of the blades corresponding to the plurality of spiral sections 211 gradually increase.

[0077] Please refer to Figure 2 In this embodiment, the feeding auger 210 has three spiral sections 211, and the rotating shafts of the three spiral sections 211 are connected in sequence. At the same time, 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. At the same time, 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 feeding 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, and 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. 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 segment 211 is smaller than the blade pitch of the second spiral segment 211, and the radial height of the blades of the first spiral segment 211 is smaller than the radial height of the blades of the second spiral segment 211. At the same time, the blade pitch of the third spiral segment 211 is greater than the blade pitch of the second spiral segment 211, and the radial height of the blades of the third spiral segment 211 is greater than the radial height of the blades of the second spiral segment 211.

[0080] That is, the feeding auger 210 can realize material conveying of three different material flow rates. At the same time, along the conveying direction of the feeding auger, the discharge flow rate corresponding to the first spiral section 211, the discharge flow rate corresponding to the second spiral section 211, and the discharge flow rate corresponding to 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 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, which can block the spiral section 211 that does not need to be fed. The material blocking member 110 can be installed at an angle 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 can be 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 discharge port, so that the feeding 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 portion of the feed port, so that the unblocked area forms the feed port 101 .

[0086] In this embodiment, there can be two material blocking members 110 , which are spaced apart. The area between the lower edges of the two material blocking members 110 can just correspond to the spiral section 211 of the required material flow, so that the feeding 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 blocks 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 placed in the box 120, so that the material blocking member can simultaneously block the second spiral section 211 and the third spiral section 211, so that the spreading device 1000 can correspond the material flow rate of the first spiral section 211 to the material flow rate.

[0089] Alternatively, in some embodiments, the spreading device 1000 has only one material blocking member 110 in a plate structure, and the feed auger has only two spiral sections 211 with different material flow rates. This one 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 can be three, four or five, etc. For example, the spreading device 1000 has three material blocking members 110, and the feeding 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 only corresponds to one spiral section 211.

[0091] Alternatively, when the spreading device 1000 has three material blocks 110, only two of the material blocks 110 can be used. The feed auger has four spiral sections 211 with different material flow rates. One of the material blocks 110 blocks one of the spiral sections 211, and the other material block 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 plate-shaped 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 . There may be multiple support members 130 . The multiple support members 130 are arranged on the box body 120 . 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 wall of the stop member 110 to maintain the position of the stop member 110 in the box body 120. The distribution position and number of support members 130 can be set according to the required arrangement position of the stop 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 cloth that can be rolled up or unrolled. 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 the 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 members 110 in the form of a winding member can be one, or the number of the material-blocking members 110 in the form of a winding member can be multiple. At least one of the multiple material-blocking members 110 is used to block a partial area of ​​the discharge 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 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, and will not be repeated here.

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

[0099] One end of the blocking member 110 is connected to the box body 120, and the other end of the blocking member 110 is foldable relative to the box body 120. The other end of the blocking member 110 is used to block part of the area of ​​the feed port when it is unfolded, so that the unblocked area forms the feed port 101.

[0100] The number of the material blocking members 110 in the form of folding parts can be one, or the number of the material blocking members 110 in the form of folding parts can 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 part is equivalent to the above-mentioned material blocking member 110 in the form of a plate structure in the unwinding state. When the sowing device 1000 has one material blocking member 110 in the form of a folding part or has multiple material blocking members 110 in the form of a folding part, 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, and 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 stopper 110 may be made of an elastic material, such as elastic fabric, so that the material stopper 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 stopper 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 feed port 101, in order to facilitate the adjustment of the size of the feed port 101, the part of the rod frame of the annular frame along the material conveying direction of the feed auger 210 can be telescopic, and at the same time, the annular frame can be detachably connected to the feed 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, Figure 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 feed 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 there are at least two spiral sections 211 with the same discharge flow rate among the multiple spiral sections 211 of the feeding auger 210, 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 granular materials, and there is no need to replace the feed auger 210, which facilitates the sowing operation and reduces costs.

[0112] To sum up, the sowing 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 installed in the feeding shell 220. The feeding auger 210 has multiple spiral sections 211, and the discharge flow rates corresponding to at least any two of the multiple spiral sections 211 are different. When the sowing device 1000 is working, the feeding port 101 is only set to correspond to one of the multiple 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 granular 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 sowing device 1000 and has all the functions of the above-mentioned sowing device 1000.

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