DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. Example

[0023] See also Figure 1-Figure 2 As shown, a drone for rice planting includes a drone body 1, a medicine box 11, a peristaltic pump assembly 12, a battery body 13 and a battery slot 14, wherein the drone body also includes four sets of foldable blades and four legs under the drone body 1; The cross-section of the medicine box 11 is T-shaped, and a plurality of snap-in holes are provided on both sides of the T-shaped edge at the top of the medicine box 11. A mounting groove 16 is provided at the bottom of the drone body 1, and the top part of the medicine box 11 is inserted into the mounting groove 16. Since matching snap-in columns 17 are provided on both sides of the inner wall of the mounting groove 16 corresponding to the positions of the snap-in holes, the snap-in holes and the snap-in columns 17 are correspondingly plugged in to complete the fixation of the medicine box 11 to the drone body 1. When the medicine box 11 is lifted up, the snap-in holes are disengaged from the snap-in columns 17, and the medicine box 11 is then translated to remove the medicine box 11 from the mounting groove 16.

[0024] A medicine delivery hole 19 is provided on one side of the T-shaped edge at the top of the medicine box 11. The medicine delivery hole 19 is a hollow structure and is connected to the inside of the medicine box 11. The medicine delivery hole 19 is provided with a hose 110 that passes into the medicine box 11. A medicine delivery column 18 is provided on one side of the inner wall of the mounting groove 16 at a position corresponding to the medicine delivery hole 19. The medicine delivery column 18 is a hollow structure and cooperates with the medicine delivery hole 19. The other side of the medicine delivery column 18 is connected to the peristaltic pump assembly 12. When the medicine box 11 is inserted into the clamping column 17 through the clamping hole, the medicine delivery hole 19 is also inserted into the medicine delivery column 18. A sealing rubber ring can be provided on the medicine delivery column 18 for sealing. When the medicine box 11 is fixed, the medicine liquid in the medicine box 11 is sucked by the peristaltic pump assembly 12, and the medicine liquid passes through the hose 110, the medicine delivery hole 19, the medicine delivery column 18, and the peristaltic pump assembly 12 and then distributed to the spray port of the drone body 1 to complete the drug spraying.

[0025] The medicine box 11 is located near the center of the drone body 1 to maintain the balance of the drone body 1, while the battery body 13 and the battery slot 14 are located on one side of the medicine box 11, and a peristaltic pump assembly 12 is arranged on the other side of the medicine box 11 to maintain the overall balance of the drone body 1.

[0026] The opening of the battery slot 14 is located at the bottom, and a slot buckle 15 is provided at the opening of the battery slot 14. Matching snap-ons are provided on both sides of the outside of the battery body 13 corresponding to the positions of the slot buckle 15. The battery body 13 is inserted into the battery slot 14 from bottom to top. At this time, the battery body 13 is fixed by the buckle and the slot buckle 15 to prevent the battery body 13 from falling. At the same time, the contacts on the top of the battery body 13 contact the contacts in the battery slot 14 to complete the power supply.

[0027] Furthermore, a sealing cover is provided on the top of the medicine box 11, which ensures that the medicine box 11 will not spill during the take-off of the drone. The sealing cover is detachable, which is convenient for cleaning or refilling the medicine box 11. A filling port is provided on the medicine box 11, and the filling port can be connected to the supply platform through a pump pipe to complete the filling of pesticides. Example

[0028] Based on Example 1, refer to Figure 1-Figure 10 , a UAV supply platform for rice planting, comprising a mobile vehicle 7 and a supply platform connected to the mobile vehicle 7, wherein Fig. 9 As shown, the supply platform can be fixed in the bucket of the mobile cart 7, and the supply platform can be flexibly transferred through the mobile cart 7, and the drone body 1 is also placed in the supply platform and fixed and then flexibly arranged following the mobile cart 7.

[0029] In another case, if Fig.10 As shown, wheels are provided at the bottom of the supply platform, and the supply platform is towed by a hook to the tail of the mobile cart 7, so that the supply platform and the UAV body 1 can be moved without affecting the loading of the mobile cart 7 itself.

[0030] Specifically, the supply platform includes an operating platform 2, a supply box 6, a limit assembly 3 and a replacement assembly 4. The operating platform is a rectangular box structure. The surface of the operating platform is used to park the drone body 1, so the size of the operating platform is larger than the landing size of the drone body 1, providing a wider and more stable parking space for the drone body 1.

[0031] The limit assembly 3 is located in the operating platform 2. The limit assembly 3 includes a housing 37, a two-way adjustment assembly and a limit plate 31 located in the housing 37. The limit plate 31 extends out of the housing 37 and extends out of the operating platform 2. When the drone body 1 is parked on the operating platform 2, the two-way adjustment assembly is started to drive the limit plates 31 on both sides to approach the drone body 1, and the drone body 1 is clamped and limited by the limit plates 31 on both sides. The replacement component 4 includes a synchronous belt component 41, a support plate 42, and a medicine box limiting groove 43 and a battery limiting groove 44 located on the support plate 42. The synchronous belt component 41 is located in the operating platform 2, and the support plate 42 is located on the operating platform 2 and is connected to the synchronous belt component 41. The positions and sizes of the medicine box limiting groove 43 and the battery limiting groove 44 correspond to and are adapted to the medicine box 11 and the battery body 13 in the drone body 1. A cylinder 45 and a guide column are provided between the medicine box limiting groove 43 and the support plate 42, and a screw lifting component 46 is provided on one side of the battery limiting groove 44.

[0032] The medicine box limiting groove 43 is lifted by the cylinder 45. At this time, the bottom of the medicine box 11 is in the medicine box limiting groove 43. The four side plates 39 of the medicine box limiting groove 43 limit the medicine box 11. As the cylinder 45 is lifted, the medicine box limiting groove 43 drives the medicine box 11 to the top of the inner wall of the installation groove 16, so that the clamping hole of the medicine box 11 is disengaged from the clamping column 17, and then the medicine box limiting groove 43 is driven by the synchronous belt assembly 41 to move horizontally to remove the medicine box 11 from the drone body 1. The process of installing the full medicine box 11 on the drone body 1 through the medicine box limiting groove 43 is the opposite of the above-mentioned steps of removing the medicine box 11.

[0033] Similarly, the battery limiting groove 44 is also used to remove the battery body 13 through the screw lifting assembly 46 and the synchronous belt assembly 41. The entire replacement process reduces manual participation, reduces labor intensity, and reduces contact with pesticides.

[0034] The supply box 6 is fixed on the operating platform 2 and is located on one side of the synchronous belt assembly 41. The supply box 6 is provided with a filling medicine barrel, a charging assembly and a spare battery. When the empty medicine box 11 is replaced by the replacement assembly 4, it is sent to the supply box 6. The medicine in the filling medicine barrel is injected into the empty medicine box 11 by connecting the pump tube, and then the filled medicine box 11 is connected to the drone body 1 through the replacement assembly 4; similarly, the replaced battery body 13 is sent to the side of the supply box 6. At this time, the battery body 13 can be removed, and the fully charged rush battery is placed in the battery limit slot 44, and then installed in the drone body 1 through the replacement assembly 4. At the same time, the charging assembly can also be connected to the battery body 13 for charging. A battery can be set in the charging assembly, and the charging assembly can also be connected to the power generation device of the mobile car 7, so that the mobile car 7 can charge the battery body 13 or the spare battery.

[0035] See also Figure 1-Figure 3 , specifically describe the structure and working process of the limit assembly 3. The bidirectional adjustment assembly includes a positive threaded screw 32, a rotating shaft 33 and a negative threaded screw 34 from left to right. Since the positive threaded screw 32, the rotating shaft 33 and the negative threaded screw 34 are connected as a whole through a coupling, when the rotating shaft 33 is rotated by the motor drive assembly 35, the positive threaded screw 32 and the negative threaded screw 34 rotate synchronously. Since the two limit plates 31 are respectively connected to the positive threaded screw 32 and the negative threaded screw 34 through sliders, when the positive threaded screw 32 and the negative threaded screw 34 rotate, the two limit plates 31 will move closer or farther away synchronously.

[0036] A limit plate 31 extends out of the top of the operating platform 2 and a limit rod 38 is provided. The length of the limit rod 38 is greater than the distance between the two legs of the drone body 1. When the drone body 1 is docked on the operating platform 2, the docking position of the drone body 1 is not accurate enough. The limit rod 38 is driven to move by the two limit plates 31, and then the drone body 1 is clamped to the middle horizontal position.

[0037] Continue reading Figure 1-Figure 3 The synchronous belt assembly 41 is located at the center of the operating platform 2 and is arranged along the long axis direction of the operating platform 2. The shell 37 passes through the synchronous belts of the synchronous belt assembly 41. The synchronous belt assembly 41 will not interfere with the limit assembly 3 when it rotates. The lower edge of the support plate 42 is connected to the synchronous belt of the synchronous belt assembly 41. The operating platform 2 is provided with a groove corresponding to the position where the support plate 42 is connected to the synchronous belt assembly 41.

[0038] The synchronous belt can drive the support plate 42 and the medicine box limiting groove 43 and the battery limiting groove 44 on the support plate 42, or the replaced medicine box 11 and the battery body 13 to move along the movement direction of the synchronous belt assembly 41, that is, the support plate 42 can move back and forth from one side of the supply box 6 to the docked drone body 1.

[0039] The width of the support plate 42 is smaller than the distance between the two legs of the drone body 1. At the same time, support rollers 47 are provided on both sides of the support plate 42 along the moving direction of the synchronous belt, and the support rollers 47 play a supporting role. A tail plate 48 is provided on the side of the support plate 42 close to the supply box 6, and the width of the tail plate 48 is the same as the distance between the two legs of the drone body 1. At the same time, a side plate 39 is provided on the side of the limit rod 38 away from the supply box 6, and the side plate 39 is perpendicular to the limit rod 38.

[0040] Therefore, when the support plate 42 moves toward one side of the drone body 1, the front end of the support plate 42 extends under the drone body 1, and the tail plate 48 of the support plate 42 abuts against the legs of the drone body 1. As the support plate 42 moves with the synchronous belt assembly 41, the tail plate 48 drives the drone body 1 to move toward the side plate 39 until the synchronous belt assembly 41 moves into place. At this time, the drone body 1 is abutted by the side plate 39 and the tail plate 48 at the front and rear ends respectively, and at the same time, the left and right sides are abutted by the limit rod 38. At this time, the drone body 1 completes the limit fixation.

[0041] Furthermore, the operating platform 2 is provided with a moving groove 310 corresponding to the direction in which the limit plate 31 moves along the two-way adjustment component, and a slide rail assembly 36 is provided between the bottom of the shell 37 and the bottom of the inner wall of the operating platform 2. The slide rail assembly 36 is arranged along the transmission direction of the synchronous belt assembly 41. The operating platform 2 is provided with a slide groove 311, and the distance between the two groups of the slide grooves 311 is the same as the distance between the two legs of the drone body 1.

[0042] When the drone body 1 is limited by the tail plate 48, the side plate 39 and the limit rod 38, when the drone body 1 needs to be retracted to the side close to the supply box 6, the tail plate 48 and the limit rod 38 are connected by bolts, and the synchronous belt assembly 41 is reset at this time, and the synchronous belt drives the tail plate 48 and the limit rod 38 to be retracted together, and the drone body 1 is supported by the side plate 39 to slide toward the position of the supply box 6. The width of the moving groove 310 and the sliding groove 311 are both smaller than the diameter of the legs of the drone body 1, so as to prevent the legs of the drone body 1 from falling into the gap between the moving groove 310 and the sliding groove 311.

[0043] like Figure 4 As shown, the drone body 1 is parked on the operating platform 2 , and the two sets of limit rods 38 are at the maximum distance, which is convenient for parking the drone body 1 .

[0044] like Figure 5 As shown, at this time, the limit assembly 3 is started, and the limit rods 38 on both sides are synchronously moved to the middle, and at this time the drone body 1 is in a horizontal center position.

[0045] like Figure 6As shown, the replacement component 4 is started, the support plate 42 moves toward the side plate 39, and the tail plate 48 abuts against the legs of the drone body 1 until the other side leg of the drone abuts against the side plate 39. At this time, the drone body 1 is limited and fixed on all four sides by the side plate 39, the tail plate 48 and the limit rod 38.

[0046] like Figure 7 As shown, the tail plate 48 is fixed with the limit rod 38 by bolts. When the tail plate moves through the synchronous belt assembly 41 and drives the limit rod 38 to move, since the limit rod 38 is connected to the limit plate 31 and the limit assembly 31 as a whole, and the shell 37 is slidably connected to the operating platform 2 through the slide rail assembly 36, the tail plate 48 can drive the limit assembly 31 to move toward the supply box 6 as a whole. Since the limit rod 38 clamps the drone body 1 and the side plate 39 also abuts against the legs of the drone body 1, the drone body 1 is moved toward the supply box 6 by the tail plate 48, the limit rod 38 and the side plate 39, which makes it convenient for the drone body 1 to be close to the supply box 6 to replenish the medicine or charge. At this time, the drone body is in a standby state, which is convenient for transportation. Fig. 9 or Fig.10 As shown, the supply box 6 is provided with a folding canopy, and the drone body 1 is moved under the folding canopy for protection.

[0047] like Figure 1 , Figure 2 and Figure 8 As shown, pressing assemblies 5 are provided on both sides of the battery limiting groove 44 corresponding to the positions of the slot buckle 15, and the pressing assembly 5 includes a push rod 51, a spring piece 52 and a hinge rod 53. One end of the push rod 51 is provided with a slope, and the slope cooperates with the press buckle of the slot buckle 15. The other end of the push rod 51 is hinged to the battery limiting groove 44, and the spring piece 52 is located between the push rod 51 and the battery limiting groove 44. The spring piece 52 is a W-shaped structure, one end of the spring piece 52 is fixed to the battery limiting groove 44, and the middle part of the spring piece 52 extends into the battery limiting groove 44. One end of the hinge rod 53 is hinged to the middle part of the push rod 51, and the other end of the push rod 51 is connected to the spring piece 52.

[0048] Specific as Figure 8 As shown in A in the figure, the battery body 13 is inserted and fixed in the battery slot 14, and the snap-in connections on both sides of the battery body 13 are snap-connected with the slot snap-in 15, so the battery body 13 will not fall off.

[0049] like Figure 8As shown in B, the two groups of pressing components 5 are respectively located on both sides of the battery limiting groove 44 and correspond to the positions of the slot buckle 15. When the support plate 42 moves the battery limiting groove 44 to the bottom of the slot buckle 15, the battery limiting groove 44 rises through the screw lifting component 46. At this time, the spring piece 52 is in a reset state, and the protruding part of the spring piece 52 is located in the battery limiting groove. The hinge rod 53 is retracted to drive the push rod 51 to be close to the battery limiting groove 44. When the battery limiting groove 44 rises, since the push rod 51 is higher than the battery limiting groove 44, the push rod 51 contacts the slot buckle 15 first, and the push rod 51 pushes the snap of the slot buckle 15 to unlock. At this time, the battery body 13 in the battery groove 14 falls into the battery limiting groove 44 below under the action of gravity.

[0050] like Figure 8 As shown in C, the battery body 13 falls completely into the battery limiting groove 44 under the action of gravity. At this time, the battery limiting groove 44 can be retracted and sent back to the supply box 6, and then the fully charged battery body 13 is reinserted into the battery limiting groove 44. At this time, the battery body 13 is compressed outward by squeezing the spring sheet 52 by its own gravity, and the hinged rod 53 connected to the spring sheet 52 drives the top rod 51 to open outward.

[0051] like Figure 8 As shown in D, the battery body 13 is in the battery limiting groove 44. At this time, the push rod 51 is opened to both sides, and the battery limiting groove 44 is lifted up again through the screw lifting assembly 46. At this time, the push rod 51 will not contact the slot buckle 15 after opening. At the same time, after the battery limiting groove 44 is lifted, the fully charged battery body 13 is sent into the battery slot 14 until the bayonet of the battery body 13 is engaged with the slot buckle 15.
