The dispensing system includes an auger, a housing, and a motor. The auger includes a shaft and helical blades; the helical blades are spirally wound around the shaft, and the tail end of the helical blades has an opening formed between the tail end of the first blade segment and the second blade segment. One end of the shaft is connected to the motor for transmission. After the controller of the unmanned equipment receives a stop feeding command, the controller controls the motor to stop, so that when the auger is stopped, the opening is in an upward position.

The seeding systems mounted on these unmanned devices can be used to spread pesticides, seeds, powders, and other materials to complete the corresponding seeding operations.

[0004] In related technologies, material leakage can occur from the spreading system after the spreading operation stops. Therefore, the leakage problem of spreading systems has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a seeding system and a drone for unmanned equipment, which can effectively improve the problem of seed leakage in seeding systems.

[0024] Furthermore, the cavity wall of the feeding chamber includes a first side wall and a second side wall disposed opposite to each other;

[0025] The end of the shaft away from the motor extends out of the first sidewall and is connected to the spreading device.

[0026] Furthermore, the cavity wall of the feeding chamber includes a first side wall and a second side wall disposed opposite to each other;

[0027] The outer contour of the spiral blade is provided with a groove, and the groove and the outer shell form a channel for material to pass through, so as to convey material to the tail end of the spiral blade through the groove. The groove and the first sidewall are located on the same plane.

In this way, because the spiral blades are spiral-shaped, their tail ends can bear the material, effectively preventing the material at the tail end of the spiral blades from falling under its own gravity and causing leakage. Therefore, the unmanned equipment spreading system and drone provided in this embodiment of the invention can effectively prevent material leakage from the auger of the spreading system.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0065] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0066] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0067] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0070] In related technologies, material leakage occurs from the spreading system of unmanned equipment after the spreading operation stops. The designers of this invention discovered during their research that this problem arises because the spreading system uses an auger to transport the material, and when the auger stops rotating, material easily falls from the opening at the tail end of the auger, causing leakage. Therefore, this invention provides an auger that improves the material leakage problem in spreading systems, as well as a spreading system and unmanned equipment using this auger.

[0071] Please see Figure 1 This invention provides an auger applied to the spreading system 10 of an unmanned device 1 for conveying materials, which effectively improves the problem of material leakage. The unmanned device 1 can be used to spray pesticides, water, or other liquids, or it can also spray solid materials. The unmanned device 1 can be an unmanned vehicle, drone, or unmanned boat, and can be applied in agricultural, industrial, and other scenarios. In the field of plant protection, various operating equipment can be installed on the unmanned device 1 to achieve operations such as spraying pesticides, seeds, and powders.

[0072] The unmanned vehicle can travel on land and can be used in the agricultural industry for plant protection operations such as spraying pesticides or irrigating crops; it can also be used in forest fires for operations such as spraying fire extinguishing liquid; or it can spray solid materials onto target areas.

[0073] This drone can be used for agricultural plant protection operations, spraying crops with liquids such as pesticides and water; it can also be used for spraying fire extinguishing liquids during forest fires; or it can spray solid materials onto target areas.

[0074] This unmanned vessel can be used for water spraying operations, spraying liquids such as pesticides and water; or it can spray solid materials onto target areas.

[0075] In this embodiment, the unmanned device 1 is a drone used for spraying solid materials as an example for specific explanation.

[0076] The unmanned device 1 includes a fuselage 2, arms 3, landing gear 4, a power unit 5, and a dispersing system 10. The arms 3 are located on both sides of the fuselage 2 and connected to it. The landing gear 4 is fixed to the underside of the fuselage 2 to ensure the stability of the unmanned device 1 during takeoff and landing. The power unit 5 is fixed to the end of the arms 3 furthest from the fuselage 2, providing lift for the unmanned device 1's flight. The dispersing system 10 is located on the fuselage 2 and is used to collect and disperse materials.

[0077] Please see Figures 2-5 The spreading system 10 may include an auger 100, a housing 200, a sensing device 300, a motor 400, a spreading device 500, a storage container 600, a transmission assembly 700, and an outer sleeve 800.

[0078] Please continue reading. Figure 2 The storage container 600 is mounted on the machine body 2 and connected to the outer shell 200 for storing materials. The bottom of the storage container 600 is provided with a discharge port (not shown) for discharging materials into the outer shell 200.

[0079] Please continue reading. Figure 3 The outer casing 200 has a feed inlet 210 at its top, which corresponds to the discharge outlet of the storage container 600. For example, it can be connected to the discharge outlet or located below it. A feeding chamber 220 is provided inside the outer casing 200, and the feed inlet 210 communicates with the feeding chamber 220. In this embodiment, two feeding chambers 220 can be selected, both of which communicate with the feed inlet 210. A partition shell 230 can be provided inside the outer casing 200 to divide the internal cavity of the outer casing 200 into two feeding chambers 220.

[0080] Please continue reading. Figure 4 The side of the separator housing 230 away from the feeding chamber 220 is recessed to form a receiving cavity 231, which is used to receive and install the motor 400.

[0081] Please see Figure 3 and Figure 6 The feeding chamber 220 has a wall including a first side wall 241 and a second side wall 242 disposed opposite to each other, and the outer shell 200 is provided with a mounting plate 250. One side of the mounting plate 250 and the second side wall 242 together form a mounting cavity 251, which communicates with the feeding chamber 220 and is used to partially accommodate the auger 100 within the mounting cavity 251 when the auger 100 is accommodated within the feeding chamber 220.

[0082] Please continue reading. Figure 5 One end of the outer casing 200 is provided with a transmission cavity 260, which is connected to both the accommodating cavity 231 and the feeding cavity 220. The transmission cavity 260 is used to accommodate and install the transmission assembly 700. Since the transmission cavity 260 is connected to both the accommodating cavity 231 and the feeding cavity 220, the transmission assembly 700 can be driven by the motor 400, and the auger 100 can be driven by the transmission assembly 700, thereby realizing power transmission. The motor 400 can drive the auger 100 to rotate around its own axis through the transmission assembly 700. Optionally, the transmission assembly 700 can adopt a gear transmission structure.

[0083] Please continue reading. Figure 6 The other end of the outer shell 200 is provided with a plug-in cavity 270, which is connected to the feeding cavity 220 and is used to allow the auger 100 to extend into the feeding cavity 220 through the plug-in cavity 270.

[0084] Please see Figure 4 and Figure 7 An auger 100 is disposed inside an outer sleeve 800, which is connected to a spreading device 500. The auger 100 is used to convey the material inside the outer sleeve 800 to the spreading device 500 so that the spreading device 500 can spread the material. After the outer sleeve 800 and the auger 100 pass through the insertion cavity 270 and extend into the feeding cavity 220, the auger 100 can cooperate with the transmission assembly 700.

[0085] Please continue reading. Figure 4 The sensing device 300 is disposed on the housing 200 and is used to sense the stopping position of the auger 100. In this embodiment, the sensing device 300 is disposed on the side of the mounting plate 250 away from the mounting cavity 251, which facilitates sensing the stopping position of the auger 100 and improves the accuracy of detection. Optionally, the sensing device 300 can be a Hall sensor.

[0086] Please see Figure 8The auger 100 includes a shaft 110, a mounting component 120, and spiral blades 130. The mounting component 120 is located at one end of the shaft 110 and has a sensor 140 mounted on it. Optionally, the sensor 140 is a magnet and can be sensed by a Hall effect sensor. One end of the shaft 110 with the mounting component 120 is connected to a motor 400 for transmission, and the other end extends out of the feeding chamber 220 and is connected to a spreading device 500. The spiral blades 130 are spirally wound around the shaft 110, and an opening 131 is provided at the tail end of the spiral blades 130. In this embodiment, "tail end" refers to the output end of the auger 100 when conveying materials.

[0087] The shaft 110 is configured such that, upon receiving a stop feeding command from the unmanned equipment 1 and the sensor 140 being first sensed by the sensor 300 of the spreading system 10, the shaft 110 stops rotating around its own axis, and the opening 131 faces upward. The stop feeding command represents a command to stop the control motor 400 from operating, thereby stopping the auger 100 from rotating and stopping the material conveying. The stop feeding command can be issued by the user via an operating device.

[0088] This ensures that when the auger 100 is stopped, the opening 131 at the tail end of the spiral blade 130 is facing upwards. When the auger 100 is not conveying, material accumulates between the tail end of the spiral blade 130 and the outer sleeve 800. Since the spiral blade 130 is spiral-shaped, the inner walls of the spiral blade 130 and the outer sleeve 800 can support the material, effectively preventing the material at the tail end of the spiral blade 130 from falling under its own gravity and causing leakage.

[0089] Please see Figure 9 The unmanned device 1 also includes a controller 20, which is electrically connected to the spreading system 10 and is used to control the spreading system 10 to perform or stop spreading operations. Further, in this embodiment, both the sensing device 300 and the motor 400 are electrically connected to the controller 20. The sensing device 300 is configured to send a sensing signal to the controller 20 when it first senses the sensing element 140 after receiving a stop feeding command, so that the controller 20 controls the motor 400 to stop based on the sensing signal, thereby causing the shaft 110 to stop rotating around its own axis and the opening 131 to face upwards.

[0090] It should be noted that, since the sensing element 140 is mounted on the mounting component 120, the sensing element 140 can be sensed by the sensing device 300 once for every revolution of the shaft 110 driven by the motor 400. Even if the sensing device 300 senses the sensing element 140, it will not send a sensing signal if a stop feeding command is not received. Therefore, the controller 20 does not control the motor 400 to stop, ensuring normal material conveying. After the controller 20 receives the stop feeding command, to ensure the auger 100 is in the stopped state, the controller 20 does not immediately control the motor 400 to stop, but continues to control the motor 400 to run until the sensing device 300 senses the sensing element 140 for the first time after the controller 20 receives the stop feeding command, and then sends a sensing signal to the controller 20. The controller 20 then controls the motor 400 to stop based on the sensing signal. In this way, when the motor 400 stops, the shaft 110 stops rotating around its own axis, and the sensing element 140 is in the position sensed by the sensing device 300. In this state where the auger 100 is stopped, the opening 131 remains facing upward, thereby preventing the material at the tail end of the spiral blade 130 from falling under its own gravity and causing leakage.

[0091] Optionally, in this embodiment, since there are two augers 100, each auger 100 can be equipped with a sensor 140, and thus there can be two sensing devices 300, which respectively detect the sensors 140 on the two augers 100, thereby ensuring that when the two augers 100 are in the stopped position, the openings 131 at the tail ends of both augers 100 are facing upwards. Alternatively, in other embodiments, only one sensing device 300 and sensor 140 can be provided, detecting only the stopped position of one auger 100. This sensing device 300 can emit a sensing signal to achieve synchronous control of the two augers 100 by the controller 20. To ensure that the openings 131 of both augers 100 are facing upwards when stopped, it is only necessary to ensure accurate initial installation position during the installation of the augers 100. That is, when the auger 100 with sensor 140 is in the position sensed by the sensing device 300, the opening 131 of that auger 100 is facing upwards, and then the other auger 100 is installed in the position where the opening 131 is facing upwards.

[0092] Please continue reading. Figure 8 In this embodiment, the spiral blade 130 may include a first blade segment 132 located at the tail end and a second blade segment 133 adjacent to and connected to the first blade segment 132. The end of the first blade segment 132 away from the second blade segment 133 is provided with an end wall 134, and an opening 131 is formed between the end wall 134 and the second blade segment 133.

[0093] It should be noted that the end wall 134 is the very end from which the material is output by the spiral blade 130. The first blade segment 132 is formed by spiraling the spiral blade 130 around the shaft 110 360°, starting from the end wall 134. The second blade segment 133 is formed by spiraling the spiral blade 130 around the shaft 110 360°, starting from the connection point with the first blade segment 132. In other words, the opening 131 is formed between the corresponding parts of the end wall 134 at the tail end of the spiral blade 130 and the second blade segment 133. This ensures that the tail end of the auger 100 faces upwards, and the opening 131 remains upwards, preventing material leakage.

[0094] Please see Figure 8 and Figure 10 Furthermore, the shaft 110 is configured such that, after the unmanned equipment 1 receives a stop feeding command and the sensing element 140 is first sensed by the sensing device 300 of the spreading system 10, the shaft 110 stops rotating around its own axis, and the end wall 134 is in the same horizontal plane as the sensing element 140 with the end wall 134 facing upward. That is, when the shaft 110 is in the stopped state, the end wall 134 and the sensing element 140 can be considered to be in the same horizontal plane and flush, with the end wall 134 facing upward, thereby ensuring that the tail end of the spiral blade 130 faces upward and preventing material leakage.

[0095] It should be noted that the position of the sensing element 140 on the mounting member 120 is not specifically limited, as long as the shaft 110 stops rotating around its own axis when the sensing element 140 is sensed by the sensing device 300, and the opening 131 faces upward. In this embodiment, the sensing element 140 can be selected to be in a horizontal position relative to the mounting member 120 when it is sensed by the sensing device 300. In other embodiments, it can also be in a vertical position or an inclined position, for example.

[0096] Furthermore, by stopping the shaft 110 from rotating around its own axis, the end wall 134 and the sensing element 140 are positioned in the same horizontal plane passing through the axis of the shaft 110. In other words, the horizontal plane where the end wall 134 and the sensing element 140 are located passes through the axis of the shaft 110, which can be considered as the tail end of the helical blade 130 being spirally wound half a turn to the horizontal, thereby improving the material-bearing capacity of the helical blade 130.

[0097] In this embodiment, the mounting member 120 is generally disc-shaped. After the auger 100 is installed in the feeding chamber 220, the mounting member 120 is housed in the mounting chamber 251. A long strip-shaped mounting portion 121 protrudes from one side surface of the mounting member 120. The mounting portion 121 has a mounting hole 122 along its length direction, and the sensing element 140 is installed in the mounting hole 122. The shaft 110 is configured such that when the unmanned equipment 1 receives a stop feeding command and the sensing element 140 is first sensed by the sensing device 300 of the dispersing system 10, the shaft 110 stops rotating around its own axis, and the end wall 134, the mounting portion 121, and the sensing element 140 are in the same horizontal plane.

[0098] It should be noted that when the shaft 110 is in a stopped state, the mounting part 121 is horizontally positioned, and the mounting hole 122, along the extension direction of the mounting part 121, is also horizontally positioned. This facilitates the sensing device 300's sensing of the sensing element 140, improving the accuracy of position detection. Furthermore, with the end wall 134, the mounting part 121, and the sensing element 140 all on the same horizontal plane, it further ensures that the end wall 134 faces upwards, ensuring that the tail end of the spiral blade 130 faces upwards, preventing material leakage.

[0099] Please see Figure 3 and Figure 11 In addition, in order to prevent material from accumulating on the side wall of the outer casing 200 during conveying, in this embodiment, a groove 135 is provided on the outer contour of the spiral blade 130.

[0100] It should be noted that, because the gap between the spiral blade 130 and the outer shell 200 is small when passing through the outer shell 200 to ensure the conveying effect, when there are materials with larger particle sizes, these large particles may block the cavity wall of the feeding chamber 220 at the position corresponding to the spiral blade 130 during the conveying process, causing material accumulation. Therefore, by providing grooves 135 on the spiral blade 130, even large particles can pass through the grooves 135 when the spiral blade 130 rotates, thereby being conveyed towards the tail end of the spiral blade 130.

[0101] Furthermore, after the auger 100 is installed in the feeding chamber 220, a channel for material passage is formed between the groove 135 and the outer casing 200, and the groove 135 and the first side wall 241 are located on the same plane. In this way, when the material is conveyed to the first side wall 241, it is not easy for the material to accumulate on the first side wall 241, and it can continue to be conveyed to the tail end of the spiral blade 130 through the groove 135. This can prevent problems such as the motor 400 burning out due to the accumulation of material on the first side wall 241, and the spiral blade 130 being damaged due to the spiral blade 130 cutting the accumulated material.

[0102] In summary, the auger 100, spreading system 10, and unmanned device 1 provided in this embodiment of the invention, when the unmanned device 1 receives a stop feeding command and the sensing element 140 is first sensed by the sensing device 300 of the spreading system 10, the shaft 110 stops rotating around its own axis, and the opening 131 faces upward. This ensures that when the auger 100 is stopped, the opening 131 at the tail end of the spiral blade 130 is in an upward-facing state. When the auger 100 is stopped conveying, because the spiral blade 130 is spiral-shaped, its tail end can bear the material, effectively preventing the material at the tail end of the spiral blade 130 from falling under its own gravity and causing leakage. Therefore, the auger 100, spreading system 10, and unmanned device 1 provided in this embodiment of the invention can effectively prevent leakage of the auger 100 in the spreading system 10. Furthermore, by providing the groove 135, material can be prevented from accumulating on the first sidewall 241, avoiding burnout of the motor 400 or damage to the spiral blade 130 due to material accumulation.

Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
