[0040] The inner cavity of the fixing frame 2 is provided with an adjustment component 6, and the adjustment component 6 includes a double-headed motor 61 embedded in the fixing frame 2. The fixing cylinder 3 is provided with a release component 7 used in conjunction with the adjustment component 6, and the release component 7 includes a threaded rod 72 rotating in the inner cavity of the fixing cylinder 3 to release the solid objects and place the solid objects in a predetermined area to achieve a solid object placement effect;

There is no need to change the delivery method midway, which is more convenient.

[0042] like Figure 5-Figure 10 As shown, the adjustment component 6 also includes a driving circular gear 62 fixed on the two output shafts of the double-headed motor 61, and the inner cavity of the fixed frame 2 is rotatably connected to a double-headed electric push rod 63, and the two piston rods of the double-headed electric push rod 63 are fixedly connected to a driven circular gear 64 used in conjunction with the driving circular gear 62. The double-headed motor 61 provides a unified driving source, which saves the driving force cost. At the same time, the double-headed electric push rod 63 adjusts the meshing stroke between the two groups of driven circular gears 64 and the two groups of driving circular gears 62, and the center of the double-headed electric push rod 63 is fixedly connected to a main bevel gear 65, and then the two groups of driving circular gears 62 and the two groups of driven circular gears 64 drive the main bevel gear 65 on the double-headed electric push rod 63 to rotate forward and reverse;

[0043] The release assembly 7 also includes secondary bevel gears 71 meshing on both sides of the main bevel gear 65 and fixedly connected with the threaded rod 72. The main bevel gear 65 drives the threaded rods 72 on the two sets of secondary bevel gears 71 to rotate in the forward and reverse directions, and the threaded rods 72 are threadedly connected with threaded sleeves 73. The bottom of the threaded sleeve 73 is fixedly connected with a connecting piece 74 that slidably cooperates with the fixed cylinder 3. The bottom of the fixed cylinder 3 is provided with a transverse groove, and the connecting piece 74 is provided with sliding openings that slidably cooperate with the transverse groove on both sides close to the fixed cylinder 3, which plays a role of sliding support for the connecting piece 74 and improves the sliding stability of the connecting piece 74. The bottom of the connecting piece 74 is fixedly connected with a positioning seat 75. The two threaded rods 72 then drive the two sets of positioning seats 75 to clamp and limit the solid objects through the connecting pieces 74 on the two sets of threaded sleeves 73. After the drone 1 cruises to the predetermined delivery area, on the contrary, it drives the two sets of positioning seats 75 to release the solid objects and delivers the solid objects to the predetermined area to achieve the delivery effect of the solid objects.

[0044] The driving assembly 8 also includes a driving bevel gear 82 fixed on the piston rod of the single-head electric push rod 81, and a differential bevel gear 83 is arranged on the outer side of the driving bevel gear 82. The two single-head electric push rods 81 adjust the meshing stroke between the two sets of driving bevel gears 82 and the differential bevel gear 83. Both sides of the differential bevel gear 83 are meshed with driven bevel gears 84, and the outer side of the driven bevel gear 84 is fixedly connected with a rotating rod 85 that rotates with the cylinder barrel 4. The two sets of differential bevel gears 83 drive the rotating rods 85 on the two sets of driven bevel gears 84 to rotate accordingly.

[0045] The supply assembly 9 also includes a cam 91 fixed on the outside of the rotating rod 85, and a connecting rod 92 is movably connected to the outside of the cam 91, and a piston 93 that slides with the cylinder barrel 4 is hinged at the bottom of the connecting rod 92. The two groups of rotating rods 85 drive the two groups of cams 91 to rotate, and the two groups of cams 91 drive the pistons 93 on the two groups of connecting rods 92 to perform work alternately in the four groups of cylinder barrels 4. The outer end of the four-way valve 94 is connected to an intake pipe 95, and an intake valve is provided on the intake pipe 95 and adopts an electric design to supply the boost pressure generated in the four groups of cylinder barrels 4 into the four groups of four-way valves 94, and the four intake pipes 95 provide air source compensation for the four groups of cylinder barrels 4 through the four groups of four-way valves 94;

[0046] The spray assembly 10 also includes a three-way pipe 101 connected to the inner end of the four-way valve 94, and the outer end of the three-way pipe 101 is connected to a three-way valve 102, and the three-way valve 102 is connected to a supply and discharge pipe 103 connected to the liquid storage pot 5. The liquid prepared in the two groups of liquid storage pots 5 is supplied to the two groups of three-way valves 102 by the two supply and discharge pipes 103, and the bottom end of the boosting pipe 104 is connected to a nozzle 105, and both ends of the boosting pipe 104 are fixedly connected to support feet 13 staggered with the nozzles 105, and the bottom of the support feet 13 is fixedly connected to a soft pad, which is convenient for stably supporting the drone 1, and the nozzles 105 are distributed in an array along the horizontal axis of the boosting pipe 104, and the nozzles of one row of nozzles 105 are designed to be vertically downward, and the nozzles of the other row of nozzles 105 are designed to be inclined at an acute angle, which is convenient for spraying and delivering liquids in different directions;

[0047] The liquid supplied into the two groups of three-way valves 102 is supplied into the four groups of four-way valves 94 through the two three-way pipes 101. At the same time, after the boost pressure in the four groups of four-way valves 94 merges with the liquid in the arrival period, the prepared liquid is evenly sprayed and delivered to the predetermined area through the nozzles 105 on the two boost pipes 104, thereby achieving the liquid spray delivery effect, reducing the delivery limitations of the drone 1, being suitable for different complex delivery scenarios, and not needing to change the delivery method midway, which is more convenient.

[0048] like Figure 11-13As shown, during the liquid spraying, it is mostly necessary to prepare the liquid to be sprayed from elsewhere and then pour it into the liquid storage pot 5. The liquid cannot be mixed while the drone 1 is flying before it reaches the spraying area, which prolongs the liquid spraying time and is inefficient. A mixing component 11 is provided in the liquid storage pot 5, and the mixing component 11 includes a stirring shaft 111 fixed on the differential bevel gear 83 and rotates with the liquid storage pot 5. The upper and lower sides of the stirring shaft 111 are both sleeved with a mixing rack 112. The two sets of differential bevel gears 83 drive the two sets of mixing racks 112 through the two stirring shafts 111 to mix the liquid added to the two sets of liquid storage pots 5. The raw materials are mixed and evenly stirred, and a mixing blade 113 is fixedly connected to the center of the stirring shaft 111, and a turbulence hole 114 is opened on the mixing blade 113. The mixing blade 113 and the turbulence hole 114 that rotate synchronously with the two stirring shafts 111 further turbulently stir the liquid raw materials in the two groups of liquid storage pots 5, thereby achieving the effect of preparing while flying, saving time and being more efficient. The outer side of the mixing blade 113 is fixedly connected to a scraping strip 115 that cooperates with the scraping wall of the liquid storage pot 5. The scraping strip 115 that rotates synchronously with the two groups of mixing blades 113 can scrape off the liquid raw materials attached to the inner walls of the two groups of liquid storage pots 5, thereby playing an auxiliary cleaning role.

[0049] A working principle of a drone delivery device: During the delivery of solid objects, the double-headed electric push rod 63 is first controlled to open and drive the two sets of driven circular gears 64 to move outward synchronously to the meshing portion of the two sets of driving circular gears 62, and then the double-headed motor 61 is controlled to open and drive the two sets of driven circular gears 64 to rotate through the two sets of driving circular gears 62 that are meshed in place. The two sets of driven circular gears 64 drive the main bevel gear 65 on the double-headed electric push rod 63 to rotate accordingly, and the main bevel gear 65 drives the threaded rods 72 on the two sets of secondary bevel gears 71 to rotate forward successively, and the two threaded rods 72 drive the connecting pieces 74 on the two sets of threaded sleeves 73 to move inward synchronously, and the two sets of connecting pieces 74 drive the two sets of After the positioning seat 75 clamps and positions the solid object, the drone 1 is remotely controlled to cruise to the delivery area with the object in the positioning state. Conversely, the two threaded rods 72 are controlled to drive the two sets of positioning seats 75 to move outward synchronously through the connecting pieces 74 on the two sets of threaded sleeves 73. After the solid objects lose the clamping force of the two sets of positioning seats 75, they fall to the delivery area under the action of their own gravity and return to their original positions. This is repeated to deliver the next round of solid objects. After the delivery of the solid objects is completed, the double-headed motor 61 is first controlled to pause, and then the double-headed electric push rod 63 is controlled to close and drive the two sets of driven circular gears 64 to move inward synchronously to disengage the meshing parts of the two sets of driving circular gears 62.

[0050] Before the liquid is sprayed, two portions of the same liquid raw material are poured into the two sets of liquid storage pots 5 respectively. The UAV 1 can also be controlled to take off and cruise. During this period, the two single-headed electric push rods 81 are controlled to start synchronously and drive the two sets of driving bevel gears 82 to move outward to the meshing part of the two sets of differential bevel gears 83, and then the double-headed motor 61 is controlled to start again. The double-headed motor 61 drives the two sets of differential bevel gears 83 to rotate through the two sets of driving bevel gears 82 that are meshed in place. The speed bevel gear 83 drives the rotating rod 85 on the two sets of driven bevel gears 84 to rotate accordingly. The two sets of rotating rods 85 drive the pistons 93 on the two sets of connecting rods 92 through the two sets of cams 91 to perform alternate reciprocating work in the cylinder barrel 4, and supply the boost pressure generated in the four sets of cylinder barrels 4 to the four sets of four-way valves 94. When the pistons 93 in the four sets of cylinder barrels 4 are in the return suction state, the suction valves on the four suction pipes 95 are controlled to open, and the outside air is sucked from the four suction pipes 95 through the four sets of four-way valves. 94 arrives in the four groups of cylinder barrels 4 to provide air source compensation for them. When the pistons 93 in the four groups of cylinder barrels 4 are in the process exhaust state, the boost pressure in the four groups of cylinder barrels 4 is supplied to the two three-way pipes 101. At the same time, the two liquid products prepared in the two groups of liquid storage pots 5 also pass through the three-way valves 102 on the two supply and discharge pipes 103 to reach the two three-way pipes 101, and are supplied to the four groups of four-way valves 94 to merge with the boost pressure, and then supplied to the two boost pipes 104, and are evenly sprayed to the predetermined spraying area by two rows of nozzles 105 with different nozzles, until the liquid level sensors 12 on the two groups of liquid storage pots 5 detect that the liquid products therein are sprayed and returned after completion, and two portions of the same liquid raw materials are added again, and so on, until the liquid product spraying is completed, first control the double-headed motor 61 to close, and then control the two single-headed electric push rods 81 to close synchronously and drive the two groups of driving bevel gears 82 to move inward and disengage from the meshing portion of the two groups of differential bevel gears 83 to the initial position;

[0051] During the cruise period when the UAV 1 is spraying and delivering the delivery area, and the two sets of driving bevel gears 82 drive the two sets of differential bevel gears 83 to rotate, the two sets of differential bevel gears 83 drive the mixing racks 112, mixing blades 113 and scraping strips 115 on the two stirring shafts 111 to rotate accordingly, and the two sets of mixing racks 112 mix and evenly stir the liquid raw materials added to the two sets of liquid storage pots 5. At the same time, the two sets of mixing blades 113 and the spoiler holes 114 thereon further disturb and evenly stir the liquid raw materials in the two sets of liquid storage pots 5. During this period, the two sets of scraping strips 115 scrape and clean the liquid raw materials attached to the inner walls of the two sets of liquid storage pots 5. During the cruise period of the UAV 1, the liquid raw materials can be stirred and prepared while flying. After the UAV 1 reaches the predetermined liquid spray delivery area, the preparation of the liquid raw materials in the two sets of liquid storage pots 5 is completed.

[0052] It should be noted that the specific models and specifications of the double-headed motor 61, double-headed electric push rod 63 and single-headed electric push rod 81 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0053] The power supply circuits of the double-headed motor 61, the double-headed electric push rod 63 and the single-headed electric push rod 81 are clear to those skilled in the art and will not be described in detail herein.
