The patent has the following problems:

[0004] First, the water tank is fixed on the belly of the drone. When the liquid medicine is added to the water tank, it is inevitable that the liquid medicine will splash or overflow, which is easy to be contaminated on the drone. The liquid medicine has certain toxicity and corrosiveness, which will reduce the life of the drone.

[0005] Second, the water tank is relatively fragile and is designed to be located in the belly of the drone. During the take-off and landing of the drone, the belly water tank is easily damaged. Summary of the invention

[0006] The object of the present invention is to provide a standard pesticide application device for a plant protection drone to solve the existing problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a standard pesticide application device for a plant protection UAV, comprising a UAV medicine box mounting frame, a bottom drag is fixedly connected to the bottom of the UAV medicine box mounting frame, a medicine box is slidably installed in the UAV medicine box mounting frame, a connecting seat is embedded and installed in the bottom drag, a snap-in hole is provided on the connecting seat, a spray pipe is fixedly connected to the bottom of the bottom drag, the spray pipe is communicated with the inside of the snap-in hole, a connecting head is fixedly connected to the bottom of the medicine box, the connecting head and the snap-in hole cooperate with each other, a drainage groove is provided in the connecting head, a sealing head is slidably installed in the drainage groove, and a ejector pin is fixedly connected in the snap-in hole.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By sliding the medicine box inside the medicine box mounting frame of the drone, the medicine liquid cooperates with the connecting head and the card hole to supply the medicine liquid to the spray pipe for spraying, so that the medicine box can be easily disassembled for filling with medicine liquid, avoiding overflow and contamination on the drone during filling, causing corrosion and damage to the key components of the drone.

[0019] 2. The torsion spring can provide a certain torque to the clamp arm, so that the clamp arm can be clamped inward on the drone medicine box mounting frame, thereby limiting the random upward movement of the medicine box and avoiding the problem of the medicine box sliding out due to the shaking of the drone during the space spraying operation.

[0020] 3. Through the cooperation between the ejector pin and the ejector head, the sealing head can be pushed upward to realize the connection between the drainage groove and the card hole. When the medicine box is lifted out of the drone medicine box installation frame, the return spring will push the sealing head downward to reset and re-seal the inside of the drainage groove, thereby realizing the quick connection between the medicine box and the spray pipe, without the need to remove the connected pipes after removing the medicine box.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0030] Example 1

[0031] A standard pesticide application device for a plant protection drone comprises a drone medicine box installation frame 1, a bottom drag 101 is fixedly connected to the bottom of the drone medicine box installation frame 1, a medicine box 3 is slidably installed in the drone medicine box installation frame 1, a connecting seat 102 is embedded and installed in the bottom drag 101, a snap-in hole 103 is provided on the connecting seat 102, a spray pipe 2 is fixedly connected to the bottom of the bottom drag 101, the spray pipe 2 is communicated with the inside of the snap-in hole 103, a connector 4 is fixedly connected to the bottom of the medicine box 3, the connector 4 and the snap-in hole 103 cooperate with each other, a drainage groove 402 is provided in the connector 4, a sealing head 403 is slidably installed in the drainage groove 402, and a thimble 104 is fixedly connected in the snap-in hole 103.

[0032] In this embodiment, by setting an octagonal drone medicine box installation frame 1 and a medicine box 3, the medicine box 3 can be slidably inserted into the drone medicine box installation frame 1, and the bottom drag 101 will drag the bottom of the medicine box 3, thereby fixing the medicine box 3 inside the drone medicine box installation frame 1, and the bottom of the medicine box 3 fits on the bottom drag 101. At this time, the connector 4 will be directly inserted into the clamping hole 103, and the ejector pin 104 fixed in the clamping hole 103 will be inserted into the drainage groove 402, pushing the plugging head 403 in the drainage groove 402 upward, as shown in FIG. Figure 2 As shown, at this time, the blocking head 403 is pushed out of the drainage groove 402, and the drainage groove 402 is not blocked by the blocking head 403, and then the medicine liquid in the medicine box 3 will flow into the clamping hole 103 through the drainage groove 402, and the clamping hole 103 is connected to the spraying pipe 2, and then the medicine liquid will enter the spraying pipe 2 for spraying. Since a bottom drag 101 is provided under the medicine box 3, the bottom of the medicine box 3 can be protected to prevent the bottom of the medicine box 3 from touching the bottom or colliding with foreign objects during the take-off and landing of the drone, thereby preventing the medicine box 3 from being damaged. Secondly, when it is necessary to add medicine liquid to the inside of the medicine box 3, the medicine box 3 can be directly pulled upward to take the medicine box 3 out of the drone medicine box mounting frame 1. At this time, the blocking head 403 loses the pushing action of the ejector pin 104, and will reset to block the drainage groove 402, thereby preventing the refilled medicine liquid from flowing out of the drainage groove 402 after the medicine box 3 is removed.

[0033] Example 2

[0034] like Figure 2 , 3As shown in , 5, a pump 105 is fixedly connected through the snap-in hole 103, a plurality of spray heads 201 are fixedly connected below the spray pipe 2, a handle 303 is fixedly connected to the top of the medicine box 3, a filling port 301 is fixedly connected to the front of the medicine box 3, a sealing cover 302 is threadedly installed on the filling port 301, a limiting frame 304 is fixedly connected to the bottom of the medicine box 3, a through hole is opened in the limiting frame 304, a connecting rod 405 is fixedly connected to the top of the sealing head 403, the connecting rod 405 is slidably matched with the through hole, a return spring 406 is sleeved on the connecting rod 405, the upper end of the return spring 406 is fixedly connected to the top head 404, the lower end of the top head 404 is fixedly connected to the sealing head 403, a sealing rubber ring 401 is fixedly connected to the lower edge of the connecting head 4, and the top head 404 is fixedly connected to the bottom of the sealing head 403.

[0035] In this embodiment, by starting the pump 105, the medicine liquid entering the clamping hole 103 can be pressurized and pumped to the spray pipe 2, and then transmitted to the spray head 201 through the spray pipe 2 to be atomized and sprayed on the crops. The handle 303 is used to facilitate the operator to lift the medicine box 3. The sealing cover 302 can be unscrewed to add medicine liquid to the inside of the medicine box 3 through the filling port 301, and then the handle 303 can be screwed on to block the filling port 301. The return spring 406 can provide a certain thrust for the sealing head 403. When the sealing head 403 loses the upward pushing force of the ejector pin 104, it will be reset under the push of the return spring 406.

[0036] Example 3

[0037] like Figure 1 , 2 As shown in , 6, hinged ears 5 are fixedly connected on both sides of the medicine box 3, and clamping arms 501 are arranged on both sides of the medicine box 3. A mounting groove 502 is fixedly connected in the clamping arm 501, and the mounting groove 502 is rotatably matched with the hinged ear 5. A connecting shaft 503 is opened in the hinged ear 5, and a torsion spring 504 is sleeved on the clamping arm 501. One end of the torsion spring 504 is fixedly connected to the inner wall of the connecting shaft 503, and the other end of the torsion spring 504 is fixedly connected to the clamping arm 501.

[0038] In this embodiment, a certain torque can be applied to the clamping arm 501 through the installation groove 502. The clamping arm 501 will be clamped on one side of the drone medicine box installation frame 1 under the torque, and the triangular clamping block at the lower end of the clamping arm 501 can be clamped on a corner of the drone medicine box installation frame 1, thereby clamping the medicine box 3 inside the drone medicine box installation frame 1. When the medicine box 3 needs to be removed, it is necessary to manually push the clamping arm 501 outward to separate the triangular clamping block on the clamping arm 501 from the drone medicine box installation frame 1, thereby releasing the fixation of the medicine box 3 and allowing the medicine box 3 to be lifted upward.

[0039] The working principle and use process of the present invention are as follows: when in use, it is necessary to manually push the clamp arm 501 outward to separate the triangular clamp block on the clamp arm 501 from the drone medicine box mounting frame 1, thereby releasing the fixation of the medicine box 3. At this time, the medicine box 3 can be lifted out from the drone medicine box mounting frame 1 using the handle 303, and then the sealing cover 302 is unscrewed and a certain amount of medicine liquid is added to the medicine box 3 using the filling port 301. When the medicine box 3 is reinserted into the drone medicine box mounting frame 1, the ejector pin 104 and the ejector head 404 cooperate with each other to push the sealing head 403 upward, so that the medicine liquid can be transported from the drain groove 402 to the inside of the clamp hole 103. Starting the pump 105 can pump the medicine liquid in the clamp hole 103 to the spray pipe 2, and finally the spray head 201 is used to atomize the medicine liquid and spray it onto the crops.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
