Description

Technical Field

[0001] This invention relates to the field of drone deployment technology, and in particular to a deployment device and deployment method thereof. Background Technology

[0002] Existing agricultural drones often experience material jamming during material delivery, requiring the integration of a dedicated mixing device. This results in significant resistance, which can damage the material and compromise effective delivery. Summary of the Invention

[0003] In view of this, the present invention proposes a dispensing device and a dispensing method thereof.

[0004] The dispensing device proposed in this invention includes:

[0005] The storage bin has a discharge port at the bottom and is used to store materials to be delivered.

[0006] A feeding bin is connected to the bottom of the storage box. The feeding bin includes an inner cavity, an inlet communicating with the inner cavity, and a feeding port communicating with the inner cavity. The inlet is connected to the outlet, and the feeding port is located on the side of the feeding bin.

[0007] A turntable is inclinedly disposed in the inner cavity, and the turntable is provided with at least two spaced feeding troughs along the circumference;

[0008] A drive mechanism is connected to the turntable. The drive mechanism is used to drive the turntable to rotate so that when the feeding trough runs to the feeding port, the material in the feeding trough is fed in, and when it rotates to the feeding port, the material in the feeding trough is discharged through the feeding port.

[0009] As can be seen from the above technical solution, the feeding device proposed in this invention places the feeding port on the side of the feeding bin. The tilted arrangement of the turntable ensures that the feeding trough and feeding port are on the same side of the turntable and both are in the direction of rotation of the turntable. This facilitates the transport of materials from the inlet to the feeding port. Furthermore, the rotation of the turntable itself simultaneously acts as a stirrer. The structure is simple, material transport is smooth, material jamming is prevented, and there is no need for a separate dedicated stirring device, thus avoiding damage to the materials. The feeding device enables quantitative feeding of materials, with controllable feeding volume, which improves operational efficiency. Moreover, the layout of the storage bin, feeding bin, turntable, and drive mechanism is reasonable, and the structure is simple and compact, effectively reducing the size of the feeding device, simplifying assembly, and lowering costs.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0021] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0022] like Figure 1-6 As shown, an embodiment of the present invention proposes a dispensing device 100, including a storage bin 10, a feeding bin 20, a turntable 30, and a driving mechanism 40. The storage bin 10 has a discharge port 101 at its bottom and is used to store materials 200 to be dispensed. The feeding bin 20 is connected to the bottom of the storage bin 10 and includes an inner cavity 21, an inlet 22 communicating with the inner cavity 21, and a feeding port 23 communicating with the inner cavity 21. The inlet 22 is connected to the discharge port 101, and the feeding port 23 is located on the side of the feeding bin 20. The turntable 30 is inclinedly disposed in the inner cavity 21, and the edge of the turntable 30 has at least two spaced feeding grooves 31 along its circumferential direction. The driving mechanism 40 is connected to the turntable 30.

[0023] For example, one application of the delivery device 100 of the present invention is for spraying pesticides by drones, and the material 200 may be a Trichogramma wasp capsule or other spherical object effective against crops.

[0024] With the development of drone technology, drones have been widely and extensively applied in many fields such as agricultural plant protection. Drone spraying has advantages such as simple operation, high efficiency, uniform spraying, good atomization effect, environmental friendliness, safety due to separation of humans and pesticides, and low cost. By setting up a delivery device 100 on an existing drone, the delivery of natural enemies of pests is a more environmentally friendly and effective way to protect plants. The delivery device 100 of this invention can fly to the destination via an agricultural drone and accurately deliver Trichogramma wasp capsules or other spherical objects effective against crops in a set quantity.

[0025] In use, the delivery device 100 of the present invention is connected to an agricultural drone, which includes a frame, an arm, a rotor power unit, and the delivery device 100 of the present invention. The arm is mechanically coupled to the frame, the rotor power unit is installed on the arm, and the delivery device 100 of the present invention is detachably installed on the frame for delivering material 200 to cultivated land.

[0026] For example, the material used is Trichogramma bee capsules for controlling corn borers. The rotor power unit rotates to drive the delivery device 100 to rise above the cultivated land and fly along the set route. The delivery device 100 delivers Trichogramma bee capsules to the cultivated land at predetermined time intervals.

[0027] Specifically, the material 200 stored in the storage bin 10 enters the inner cavity 21 from the discharge port 101 through the inlet port 22. The drive mechanism 40 drives the turntable 30 to rotate so that the feeding trough 31 feeds material when it reaches the inlet port 22, and when it rotates to the feeding port 23, the material 200 in the feeding trough 31 is fed into the farmland through the feeding port 23.

[0028] The dispensing device 100 proposed in this embodiment of the invention has the feeding port 23 located on the side of the feeding bin 20. The tilted arrangement of the turntable 30 ensures that the feeding trough 31 and the feeding port 23 are on the same side of the turntable 30 and both are in the rotation direction of the turntable 30. This facilitates the transport of material 200 from the inlet 22 to the feeding port 23. Furthermore, the rotation of the turntable 30 itself simultaneously acts as a stirrer. The structure is simple, the material 200 is transported smoothly, preventing jamming and eliminating the need for a separate dedicated stirring device, thus avoiding damage to the material 200. The dispensing device enables quantitative dispensing of material 200, with controllable dispensing volume, improving operational efficiency. Moreover, the layout of the storage bin 10, feeding bin 20, turntable 30, and drive mechanism 40 is reasonable, with a simple and compact structure, effectively reducing the size of the dispensing device 100, simplifying assembly, and lowering costs.

[0029] Optionally, the tilt angle of the turntable 30 relative to the horizontal plane is 20°-70°. Further, the tilt angle of the turntable 30 relative to the horizontal plane is 20°-45°. Specifically, the tilt angle of the turntable 30 relative to the horizontal plane can be 20°, 25°, 30°, 40°, or 45°, etc. Designing the tilt angle of the turntable 30 to 20° or higher allows the material 200 to slide down smoothly; designing it to be greater than or equal to 20° ensures that the material 200 can be smoothly dispensed. The specific design depends on actual design needs. In the embodiments of this invention, the horizontal plane is relative to the dispensing device 100 in its operating state.

[0030] Optionally, the feeding port 23 is inclined downwards on the side wall of the feeding bin 20, and the inclination angle of the feeding port 23 is the same as the inclination angle of the turntable 30. In the embodiment of the present invention, the turntable 30 and the feeding port 23 are inclined and their inclination angles are the same, which makes it easy to rotate to the feeding trough 31 at the feeding port 22 for easy feeding, and also makes it easy to rotate to the feeding trough 31 at the feeding port 23 for smooth feeding of material 200.

[0031] Optionally, the diameter of the feed inlet 22 is configured to be larger than the outer diameter of three materials 200, and the diameter of the discharge outlet 101 is configured to be greater than or equal to the diameter of the feed inlet 22, so that the materials 200 can fall smoothly into the inner cavity 21 and prevent jamming. In actual use, it often happens that two or three materials 200 get stuck at the feed inlet 22 and do not fall into the feeding trough 31, causing the feeding to be unable to proceed normally. In this embodiment, by configuring the diameter of the feed inlet 22 to be larger than the outer diameter of three materials 200, and by setting the turntable 30 to agitate the materials 200, the materials 200 can fall smoothly into the feeding trough 31, avoiding the situation of getting stuck at the feed inlet 22.

[0032] Of course, the diameter of the feed inlet 22 can also be configured to be greater than the outer diameter of 4, 5 or more materials 200, depending on the actual design requirements.

[0033] Optionally, the width of the feeding port 23 in the rotation direction of the turntable 30 is greater than the width of the feeding trough 31 in the rotation direction of the turntable 30, which facilitates material discharge and avoids the situation where the material cannot fall out of the feeding port 23 smoothly due to the feeding port 23 being too small. In the embodiments of the present invention, the width of the feeding port 23 is 1.3-2 times the width of the feeding trough 31, which can be 1.3 times, 1.5 times, 1.8 times, or 2 times, etc., depending on the actual design requirements.

[0034] Optionally, such as Figure 4 As shown, the turntable 30 is detachably connected to the drive mechanism 40; the drive mechanism 40 includes a drive motor 41, a reduction gearbox 42 and a rotating shaft 43. The drive motor 41 is connected to the reduction gearbox 42, the reduction gearbox 42 is connected to the rotating shaft 43 and installed in the feeding bin 20, and the rotating shaft 43 extends into the inner cavity 21 of the feeding bin 20 and is detachably connected to the turntable 30.

[0035] In use, the drive motor 41 drives the rotating shaft 43 to rotate through the reduction gearbox 42, thereby driving the turntable 30 to rotate. The turntable 30 and the drive mechanism 40 are detachable, which can be adjusted according to different materials 200 to accommodate the feeding of materials 200 of different sizes. By replacing the turntable 30 with different specifications, materials 200 of different diameters can be fed. The diameter of the pre-fed material 200 plus the diameter of the inner arc of the turntable 30 is smaller than the diameter of the feeding bin 20, which facilitates quick assembly and disassembly.

[0036] Optionally, as shown in 6, the turntable 30 includes a protrusion 32 and at least two spaced blocking portions 33 disposed around the protrusion 32, with a feeding trough 31 formed between adjacent blocking portions 33, and the top of both the protrusion 32 and the blocking portions 33 having an outwardly convex curved surface structure.

[0037] For example, both the protrusion 32 and the blocking part 33 have smooth surfaces, and the protrusion 32 is similar to a frustum. The top of both the protrusion 32 and the blocking part 33 is provided with an outwardly convex curved surface structure, so that the blocking part 33 and the protrusion 32 can perform the function of stirring the material 200 during rotation. Since the outer surfaces of the protrusion 32 and the blocking part 33 are smooth and the outwardly convex curved surface structure is provided, the material 200 can be stirred more flexibly, preventing damage to the material 200. The top of the protrusion 32 is close to the inner wall of the feeding bin 20, and the gap between the protrusion 32 and the inner wall of the feeding bin 20 is smaller than the diameter of the material 200, thereby preventing the material 200 from falling directly into the feeding port 23, so that the material 200 can only fall into the feeding trough 31 and reach the feeding port 23 by rotation.

[0038] Specifically, the bottom of the feeding trough 31 is provided with a support base 34 that supports the bottom of the material 200 by less than 1 / 2. The support base 34 is an arc shape that is adapted to the material 200. The transition area between the protrusion 32 and the blocking part 33 is a concave arc surface, which facilitates guiding the spherical material 200 to fall into the feeding trough 31. The feeding trough 31 is adapted to the size of a single material 200, which facilitates the control of the amount of material 200 fed, and realizes the function of precise feeding of material 200 by a single turntable 30.

[0039] Optionally, the feeding bin 20 is divided into a feeding area and a feeding completion area by the inlet 22 and the feeding port 23. The feeding trough 31 feeds material at the inlet 22, rotates through the feeding area, and then feeds material at the feeding port 23. The feeding device 100 also includes a sensor 50 and a controller 60. The sensor 50 is installed in the feeding bin 20 and located in the feeding area. The sensor 50 is used to detect whether there is material 200 in the feeding trough 31 after passing the sensor 50. The sensor 50 and the drive mechanism 40 are both electrically connected to the controller 60. When the sensor 50 detects that there is no material 200 in the feeding trough 31, the controller 60 controls the drive mechanism 40 to drive the turntable 30 to rotate continuously.

[0040] Optionally, the dispensing device 100 also includes a counter installed in the feeding hopper 20 and located in the dispensing area. The counter is electrically connected to the controller 60 and is used to count the quantity of material 200 entering the feeding port 23 from the dispensing area. The sensor 50 and the counter are implemented using the same device. If a fixed amount of material 200 is detected in the feeding trough 31, the feeding count is performed simultaneously.

[0041] In an embodiment of the present invention, the sensor 50 can detect whether the feeding trough 31, which has rotated to the feeding area, contains a fixed amount of material 200. If not, a feedback signal is sent to the controller 60, which controls the drive mechanism 40 to drive the turntable 30 to rotate. The controller continues to detect whether the next feeding trough 31, which has rotated to the feeding area, contains a fixed amount of material 200. The rotation of the turntable 30 also agitates the material 200 at the feed inlet 22 so that it can fall into the feeding trough 31. If the sensor 50 detects that the feeding trough 31 contains a fixed amount of material 200, the controller 60 controls the drive mechanism 40 to drive the turntable 30 to rotate so that the feeding trough 31 rotates to the position corresponding to the feeding inlet 23, thereby discharging the fixed amount of material 200 from the feeding inlet 23. This achieves the quantitative dispensing of material 200, and the dispensing amount is controllable, which can improve the work efficiency.

[0042] For example, the feeding trough 31 is designed with 5 compartments, each with a 72° angle. The original position is controlled by the controller 60, which includes a main control board 61 with an STM32 main control chip. The sensor 50 can be a diffuse reflection photoelectric switch, which is a commonly used counting sensor. Understandably, the sensor 50 is not limited to a miniature diffuse reflection photoelectric switch, as long as it can be used to detect materials and count feeding, and feed back material information signals to the main control board 61. Due to the tilted setting of the turntable 30, the two feeding troughs 31 located at the feed inlet 22 are used for feeding, the feeding trough 31 located in the feeding area, which corresponds to the sensor 50, is used for feeding detection, the feeding trough 31 located at the feeding inlet 23 is used for feeding material 200, and the last compartment is the empty feeding trough 31 after feeding, located in the feeding completion area. The turntable 30 rotates 72° each time. As the turntable 30 rotates, the positions of each feeding trough 31 change. The feeding trough 31 located in the feeding area for feeding detection rotates to correspond with the feeding port 23. The empty feeding trough 31 corresponding to the feeding port 23 and after the material 200 has been fed, rotates to the feeding completion area. The previously empty feeding trough 31 rotates to the feeding port 22 to re-feed material. This process is repeated until feeding is complete. If no material is detected after 5 consecutive rotations, the sensor will send an alarm signal to remind that no material is available. The storage tank 10 needs to be refilled. The alarm signal can be a buzzer, vibration, or LED light.

[0043] When sensor 50 detects that there is no material 200 in the feeding trough 31, it sends a feedback signal to the main control board 61. The main control board 61 controls the drive mechanism 40 to drive the turntable 30 to rotate until material 200 is detected. Then, it rotates the turntable 30 to correspond with the feeding port 23, completing one feeding of material 200. Each time the drive mechanism 40 receives a signal, it drives the turntable 30 to rotate by a set angle of 72°. The sensor 50 performs a no-material detection alarm or pre-feed confirmation. The feeding device 100 is controlled by the user to feed material 200. The main control board 61 communicates with the user through the STM32 main control chip and obtains the feeding instructions. The existing logic program control system realizes quantitative and angle control, and the feeding is achieved by rotating the turntable 30 to a fixed angle.

[0044] Of course, the number of feeding troughs 31 is not limited to 5, but depends on the actual design needs. Assuming the number of feeding troughs 31 is X, the angle by which the drive mechanism 40 drives the turntable 30 to rotate once is θ, θ = 360° / X; if X is 5, then θ is 72°; if X is 2, then θ is 180°; if X is 3, then θ is 120°; if X is 4, then θ is 90°; if X is 6, then θ is 60°.

[0045] For example, such as Figure 4 As shown, the controller 60 also includes a base 62, a signal transmission unit 63, and an angle sensor 64. The base 62 is connected to the feeding bin 20. The main control board 61 and the angle sensor 64 are located inside the base 62. The angle sensor 64 is electrically connected to the main control board 61 and is used to control the angle at which the drive mechanism 40 drives the turntable 30 to rotate. The signal transmission unit 63 is connected to the lower end of the base 62 and is used for signal transmission and communication with the user. The user can be a mobile phone, computer, or other terminal.

[0046] Optionally, the feeding bin 20 and the storage box 10 can be detachably connected, thereby facilitating the assembly and disassembly of the storage box 10 and the feeding bin 20.

[0047] Optionally, the storage bin 10 has a first latching part on its outer side wall at the discharge port 101, and the feeding bin 20 has a second latching part on its inner side wall at the feed port 22. The first latching part and the second latching part are rotatably latched together. Understandably, the first latching part can also be located on the inner side wall of the discharge port 101, and the second latching part can also be located on the outer side wall of the feed port 22.

[0048] Optionally, the dispensing device 100 further includes a fastener 70, which secures the dispensing bin 20 and the storage bin 10 to limit relative rotation between them.

[0049] For example, the top of the storage box 10 is provided with a feeding port 103, and the lower part of the storage box 10 is provided with a guiding part 104. The guiding part 104 is connected to the feeding port 103 and the discharge port 101, and the inner diameter of the guiding part 104 gradually decreases in the direction of the discharge port 101, forming a funnel shape.

[0050] like Figure 4-5 As shown, the feeding bin 20 also includes a connector 213, an upper shell 211, and a lower shell 212. The connector 213 is annular and forms a feed inlet 22 on the top of the upper shell 211. The lower shell 212 is connected to the bottom of the upper shell 211. The connector 213, the upper shell 211, and the lower shell 212 together form an inner cavity 21. The first latching part consists of multiple protrusions 102 on the outer periphery of the bottom of the storage bin 10. The second latching part consists of a limiting groove 2131 on the inner periphery of the connector 213 that is adapted to the bottom of the storage bin, and multiple through grooves 2132 on the top periphery of the connector 213 that communicate with the limiting groove 2131 and are adapted to the protrusions 102. The bottom of the storage bin 10 can be rotated so that the position of the protrusions 102 corresponds to or is misaligned with the through grooves 2132, so that the storage bin 10 and the feeding bin 20 can be detachably connected.

[0051] In use, the protrusion 102 is aligned with the through groove 2132 so that the bottom of the storage box 10 can be inserted into the limiting groove 2131 of the connector 213. By rotating the bottom of the storage box 10, the mounting protrusion 102 is rotated to be misaligned with the mounting slot, thus restricting the bottom of the storage box 10 in the limiting groove 2131. By rotating the mounting protrusion 102 to be aligned with the mounting slot, the bottom of the storage box 10 can be removed from the limiting groove 2131, thus achieving a detachable connection between the storage box 10 and the feeding bin 20. The fastener 70 can be an M4 screw, which is inserted from the bottom edge of the connector 213 into the inner periphery of the bottom of the storage box 10, thereby pressing the protrusion 102 on the outer periphery of the bottom of the storage box 10 tightly against the inner wall of the limiting groove 2131 of the connector 213, thereby restricting the relative rotation of the feeding bin 20 and the storage box 10, and effectively fixing the connection between the storage box 10 and the feeding bin 20.

[0052] like Figure 7 As shown, an embodiment of the present invention provides a dispensing method S100 for a dispensing device, comprising:

[0053] A dispensing device 100 is proposed, such as Figure 1-6As shown, the dispensing device 100 includes a storage bin 10, a feeding bin 20, a turntable 30, and a drive mechanism 40. The storage bin 10 has a discharge port 101 at its bottom and is used to store the material 200 to be dispensed.

The feeding trough 31 feeds material at the inlet 22, rotates through the feeding area, and then feeds material at the feeding port 23. The feeding device 100 also includes a sensor 50 and a controller 60. The sensor 50 is installed in the feeding bin 20 and located in the feeding area. The sensor 50 and the drive mechanism 40 are both electrically connected to the controller 60.

[0056] The feeding method S100 also includes: sensor 50 detecting whether there is material 200 in the feeding trough 31 passing through sensor 50; when sensor 50 detects that there is no material 200 in the feeding trough 31, controller 60 controls drive mechanism 40 to drive turntable 30 to rotate continuously.

[0057] Optionally, the dispensing device 100 also includes an alarm device that is communicatively connected to the sensor 50. The dispensing method S100 further includes: if the sensor 50 continuously detects that there is no material 200 in the feeding trough 31 for a preset number of times, the alarm device generates an alarm signal and feeds back the alarm signal to the user. The alarm signal may be a buzzer, vibration, or LED light, etc.
