[0047] During a drone spraying operation, if the solution runs out or needs to be replenished immediately, the operator refills the solution tank. The solution tank provided by this utility model allows the operator to complete the refill using a variety of refilling tools. The drone can be an unmanned vehicle or an unmanned aerial vehicle; the refilling tool can be any of a scoop, tube, bucket, or bag.

[0048] See also Figures 1 to 3 , exemplarily illustrates another specific embodiment of the solution tank and first cover provided by the present invention and their application to an unmanned aerial vehicle. The solution tank 1 provided by the present invention may include a box body 11 having a receiving cavity 12, and the box body 11 may include a head 13 located on its top side.

[0049] A guide groove 131 is formed on the top surface of the head 13 , and the guide groove 131 extends to a preset position to prevent the solution from flowing to a potential hidden danger area under the action of gravity. Figure 1 In the figure, the preset position is the side of the head 13. A first liquid replenishing port 14 is provided on the top side of the accommodating cavity 12, and the first liquid replenishing port 14 is opened in the guide groove 131. A boss 132 is further provided at the bottom of the groove body of the guide groove 131, and the table surface of the boss 132 is higher than the bottom surface of the groove body of the guide groove 131. The first liquid replenishing port 14 is specifically opened on the table surface of the boss 132. It can be understood that the preset position can also be a droplet recovery hole, and accordingly, the liquid can be recovered into the accommodating cavity 12 through the droplet recovery hole to reduce solution waste.

[0050] In addition, the solution tank 1 may also include a first cover body 15 covering the first fluid infusion port 14, and the first cover body 15 has at least one second fluid infusion port 16. The first fluid infusion port 14 and the second fluid infusion port 16 have different calibers, and a second cover body 17 may also be provided on the second fluid infusion port 16.

[0051] The solution box 1 provided by the present invention is provided with at least two different calibers of refilling ports on the top side of the box body 11 to support the operator to select different injection tools for refilling according to the environmental conditions, which is more versatile. The refilling ports of each caliber are also equipped with corresponding covers to cover the corresponding covers when the corresponding refilling ports are not needed, so as to prevent the internal splashing solution droplets from flying outside the solution box and / or to prevent external debris from falling into the solution box through the corresponding refilling ports. At the same time, the refilling ports of various calibers are all arranged on the boss. Accordingly, the solution dripping during the refilling process can be received by the guide groove and diverted to the preset position of the head to prevent the solution from flowing to the potential hidden danger area, thereby improving the safety of the refilling operation. In addition, by reusing the cover structure to set other refilling ports in addition to the first refilling port, it is possible to avoid the situation where the structural strength is reduced by directly opening multiple refilling ports on the box body, and it can reduce the difficulty of hole processing to a certain extent, making it easier to produce and manufacture.

[0052] As a preferred embodiment, the first liquid inlet 14 is a circular opening, and the ratio of its radius to the maximum length of the box's transverse cross-section can be 1:6, and the ratio of its radius to the maximum width of the box's transverse cross-section can be 1:4.5. Of course, the first liquid inlet 14 can also be configured to be sufficiently large to support the opening of a second liquid inlet 16 on the first cover 15 to accommodate a wider range of filling tools. Figure 1 In the embodiment, the first cover 15 is provided with only one second liquid replenishing port 16. In other specific application examples, the first cover 15 may be provided with multiple second liquid replenishing ports 16. Figure 2 As shown, the first cover 15 is provided with five second liquid inlet ports 16 of different sizes to support various filling tools for liquid inlet operations, which is highly versatile. It is understood that in the case of multiple second liquid inlet ports 16, a corresponding second cover 17 is provided at each liquid inlet of different sizes.

[0053] like Figure 1 As shown, a through slot 133 is further provided on one side of the head 13, with the through slot 133 extending in the height direction. The guide slot 131, where its body extends to the side of the head 13, communicates with the through slot 133. Accordingly, leaking solution, guided by the guide slot 131, flows into the through slot 133 and then, under the influence of gravity, flows to the side of the solution tank 1. This reduces the risk of leaking solution causing a short circuit in the equipment holding the solution tank, thereby reducing the risk of damage to the equipment.

[0054] In the present invention, the boss 132 is provided with a first connection portion 134 that connects to the first cover 15. When the first cover 15 and the boss 132 are connected via the first connection portion 134, the first cover 15 is positioned to cover the first fluid infusion port 14. The central axis of the boss 132 is located eccentrically with respect to the vertical central axis of the solution tank 1, and the boss 132 is positioned adjacent to the through slot 133. Accordingly, the first cover 15 is also provided with a second connection portion 151 that connects to the second cover 17. When the first cover 15 and the second cover 17 are connected via the second connection portion 151, the second cover 17 is positioned to cover the second fluid infusion port 16.

[0055] Specifically, when the first cover 15 is covering the first fluid infusion port 14, the first cover 15 is threadedly engaged with the peripheral side of the boss 132. When the second cover 17 is covering the second fluid infusion port 16, the second cover 17 is snap-fitted to the first cover 15. Of course, the second cover 17 can also be threadedly engaged with the first cover 15.

[0056] More specifically, a flexible connecting band 18 is further provided on the first cover 15, the free end of which is connected to the second cover 17. This flexible connecting band 18 reduces the possibility of the second cover 17 being lost. Furthermore, a plurality of screw-assisting plates 152 may be provided on the first cover 15 and / or the second cover 17. On the first cover 15, the plurality of screw-assisting plates 152 are evenly distributed around the second fluid infusion port 16 to facilitate the operator in twisting the first cover 15 to expose the first fluid infusion port 14, or in placing and tightening the first cover 15 over the first fluid infusion port 14. It is understood that a connecting band structure may also be provided on the head 13, the free end of which may be connected to the first cover 15, to reduce the possibility of the first cover 15 being lost.

[0057] In a specific application example of the solution tank 1 provided by the present invention, the bottom surface of the guide groove 131 can be tilted from high to low, and the connection point between the guide groove 131 and the through groove 133 can be located at the bottom surface of the lower side of the guide groove 131. Accordingly, the solution dripping into the guide groove 131 can flow into the through groove 133 under the action of gravity. Here, the width of the through groove 133 is narrowed from top to bottom to converge the dripping solution.

[0058] like Figure 1As shown, the top surface of the head 13 is further provided with a secondary guide groove 135, and the other side of the head 13 is further provided with a secondary through groove (not shown, refer to through groove 133). The secondary through groove is located on the opposite side of the through groove 133. The secondary guide groove 135 is connected to the groove body of the secondary through groove. The position where the secondary guide groove 135 is connected to the groove body of the secondary through groove is located on the opposite side of the position where the guide groove 131 is connected to the through groove 133. The secondary guide groove 135 and the secondary through groove can assist in the diversion and confluence of liquid droplets to cope with some unexpected situations such as solution splashing.

[0059] In the present invention, the box body 11 also includes a main body 19 located at the bottom side of the head 13. The horizontal cross-section of the connection between the main body 19 and the head 13 is narrowed, and the horizontal cross-sectional area of ​​the accommodating cavity 12 in the main body 19 decreases from top to bottom, so as to help reduce the probability of solution remaining on the inner wall of the accommodating cavity 12.

[0060] Furthermore, in a specific application example, the bottom side of the main body 19 is further provided with a liquid outlet 191 for outputting the solution, and a reinforcement portion 192 is further provided on the side of the main body 19 to reduce the possibility that the main body 19 of the box body 11 supporting the accommodating cavity 12 will deform due to insufficient structural strength when subjected to a large solution pressure. Here, the reinforcement portion 192 is located between the liquid outlet 191 and the bottom side of the head 13. The specific structure of the reinforcement portion 192 can be a depression concave into the box body 11 (such as Figure 1 ), or it may be a protrusion protruding out of the box (not shown).

[0061] Furthermore, in another specific application example, the liquid outlet 191 may include a pumping connection pipe 193 and a water receiving pipe (not shown) respectively connected to the accommodating chamber 12, wherein the pipe body of the pumping connection pipe 193 is arranged to extend obliquely, while the pipe body of the water receiving pipe is arranged vertically. The pumping connection pipe 193 is mainly used to communicate with the solution input port of the pump body (not shown) to transport the solution in the accommodating chamber 12 to the pump body, and then the pump body pressurizes the solution and inputs it to the corresponding spraying end, such as the nozzle.

[0062] Here, the location where the water receiving pipe communicates with the accommodating chamber 12 is located at the lowest position of the accommodating chamber 12. Preferably, the lowest position is a tapered depression (not shown) located at the lowest position in the height direction, and the water receiving pipe is connected to the bottom of the tapered depression. The water receiving pipe and the tapered depression structure can be used to quickly drain the accumulated liquid in the accommodating chamber 12 under specific demand scenarios.

[0063] like Figure 3As shown, the present invention also provides a drone 2, which may include a frame 21 and the solution tank 1 as described above, and the solution tank 1 is arranged on the frame 21. It can be understood that the drone 2 carries the solution tank 1 as described above to operate. When performing the rehydration operation, the operator can selectively use the adapted rehydration port to rehydrate according to all the current filling tools, thereby reducing the possibility of droplets splashing out of the box 11 during the rehydration process and reducing the probability of the corresponding electronic components on the drone 2 being short-circuited and burned by the droplets. At the same time, the solution that leaks during the rehydration process can also be diverted through the provided guide groove 131 to avoid the risk of short circuits caused by the non-directional flow of the solution to the electronic components on the drone 2, making the rehydration operation safer.

[0064] In a specific application example, the main body 19 narrows rapidly at the connection with the head 13. Accordingly, in the horizontal direction, the head 13 has a flange (not shown) extending circumferentially relative to the main body 19, and part of the lower surface of the flange can serve as a connecting surface for connecting the solution tank 1 and the frame 21.

[0065] The drone 2 provided by the present invention may also include a spray system (not shown in the figure), a pumping system (not shown in the figure) and an infusion pipeline (not shown in the figure). The pumping system is used to pump the solution in the solution tank 1 into the infusion pipeline, so that the solution is transported to the spray system via the infusion pipeline, and finally the spray system atomizes the solution into fine droplets and evenly sprays them on the operating target such as crops.

[0066] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered by the protection scope of the present invention.
