[0007] Preferably, a group of the arc-shaped shift plates are fixedly connected to a plurality of I-shaped elastic members on the outer wall of the bottom end, the outer wall of the bottom end of each group of the I-shaped elastic members are respectively fitted and slidably connected to the inner wall of the bottom end of each group of the arc trough plates, and a plate groove is provided on the top side plate body of each group of the arc trough plates, and the inner wall of each group of the plate grooves can be intermittently fitted and engaged with one side plate body of each group of the arc-shaped shift plates.

[0008] Preferably, each of the two second clamping structures includes a grooved barrel plate fixedly connected to the support rod body, and a beveled slot block is slidably connected to the top inner wall of the grooved barrel plate, and a double-headed arc column is fixedly connected to the central bottom end of the beveled slot block.

[0009] Preferably, the double-headed arc column and the inner wall of the grooved drum plate are fitted and slidably connected, and the two ends of the grooved drum plate near the top are slidably connected with oblique end rods, and the inclined ends of the two oblique end rods are respectively fitted and connected to the outer wall of the double-headed arc column near the top.

[0010] Preferably, the two oblique end rods are provided with an arc-shaped groove on one side of the rod body close to the double-headed arc column, and the oblique groove block and the inner walls of the two arc-shaped grooves can be intermittently fitted and connected, and the bottom end plate of one side of the support plate frame and the top outer wall of the oblique groove block are fixedly connected.

As a result, the arc-shaped plate and the arc-shaped paddle plate can be rotated from an inclined state to a horizontal state through rotation, thereby releasing the simultaneous contact and adhesion connection of a group of symmetrical arc groove plates. When toggling the arc-shaped paddle plate, it is necessary to first press the arc-shaped paddle plate downward to release the limited engagement of the arc-shaped paddle plate, so that the arc-shaped paddle plate is forced to squeeze the multiple I-shaped elastic parts on the bottom end, thereby causing it to deform downward and disengage from the pre-engaged plate groove. At the same time, the multiple rectangular blocks perform limited downward sliding in the corresponding rectangular grooves, thereby separating the fixed connection between the connecting plate and the abutting plate, achieving the effect of quick disassembly.

[0015] The present invention lifts the pesticide storage tank, and the upward-moving support plate frame will simultaneously drive the inclined groove block and the double-headed arc column to move upward together, thereby pushing the two inclined end rods fitted therewith to move in opposite directions, so that the spring fixed to the outer wall of the grooved drum plate is deformed by the force, and the inclined end rod can be driven to reset by the elastic force of the spring itself. Therefore, the second layer of fixed connection can be quickly disassembled by simply moving upward, thereby ensuring the stability of the connection and enabling high-efficiency disassembly.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a detachable pesticide liquid storage tank drone device, including a plant protection drone 1, a frame 11 is fixedly connected to the outer walls of both ends of the plant protection drone 1, and a pesticide liquid storage tank 12 is provided on the plant protection drone 1. The outer walls of both ends of the pesticide liquid storage tank 12 are respectively fixedly connected with a connecting plate 13 and an abutment plate frame 14, and a disassembly portion 2 is provided in the inner walls of the two frames 11. The two disassembly portions 2 each include an abutment plate 21 fixedly connected to the inner walls of the two frames 11 and a support rod 29. The two connecting plates 13 and the two abutment plates 21 can be fitted and connected, and a first clamping structure is also jointly provided between the two connecting plates 13 and the two abutment plates 21, and a second clamping structure is jointly provided between the two abutment plate frames 14 and the two support rods 29; The pesticide storage tank 12 on the plant protection drone 1 is on the same horizontal line as the bottom ends of the two frames 11 .

[0020] Adopting the above solution: when removing the pesticide storage tank 12 placed under the plant protection drone 1, the arc-shaped shift plate 25 on the arc groove plate 22 is moved to drive the arc panel 23 and the multiple I-shaped elastic members 27 connected by the multiple rectangular blocks 26 to perform limited sliding, such as Figure 3 and Figure 5 As shown, the arc plate 23 and the arc-shaped shift plate 25 are rotated from the tilted state to the horizontal state, thereby releasing the simultaneous contact and connection of a set of symmetrical arc groove plates 22, achieving the effect of quick disassembly; Then the pesticide storage tank 12 is lifted up, and the support plate frame 14 that is forced to move upward will simultaneously drive the inclined groove block 231 and the double-headed arc column 232 to move upward together, thereby pushing the two inclined end rods 233 that are attached to them to move in opposite directions, thereby squeezing the spring 236 fixed to the outer wall of the groove drum plate 230 and deforming it. Subsequently, the elastic force of the spring 236 itself can be used to drive the inclined end rod 233 to reset, so that the second layer of fixed connection can be quickly disassembled by simply moving upward, ensuring the stability of the connection and efficient disassembly.

[0021] The two first clamping structures each include two groups of symmetrical arc groove plates 22. The bottom ends of the two groups of arc groove plates 22 are fixedly connected to the connecting plate 13 and the top outer wall of the abutting plate 21 respectively. The inner walls of the two groups of arc groove plates 22 are fitted and rotatably connected with a group of symmetrical arc panels 23, and a plurality of rectangular grooves 24 are opened on the outer wall of one group of arc panels 23. An arc-shaped shifting plate 25 is also fitted and connected to the outer wall of one group of arc panels 23. A group of arc-shaped shifting plates 25 and the inner wall of the arc groove of the arc groove plate 22 are fitted and slidably connected, and a group of arc-shaped shifting plates 25 are fitted and slidably connected. A plurality of rectangular blocks 26 are fixedly connected to the inner wall of the plate 25, and each group of rectangular blocks 26 is respectively fitted and slidably connected to the inner wall of each group of rectangular grooves 24. A plurality of I-shaped elastic members 27 are fixedly connected to the outer wall of the bottom end of a group of arc-shaped shift plates 25, and the outer wall of the bottom end of each group of I-shaped elastic members 27 is respectively fitted and slidably connected to the inner wall of the bottom end of each group of arc-groove plates 22, and a plate groove 28 is opened on the top side plate body of each group of arc-groove plates 22, and the inner wall of each group of plate grooves 28 can be intermittently fitted and snapped into the plate body of one side of each group of arc-shaped shift plates 25.

[0022] The above solution is adopted: the operator manually moves the arc-shaped dial plate 25 on the arc groove plate 22, so that it drives the arc plate 23 connected by multiple rectangular blocks 26 to rotate together, and the rotating arc-shaped dial plate 25 also drives the multiple I-shaped elastic members 27 connected to the bottom end to slide in a limited manner, so that the arc-shaped dial plate 25 can be rotated, such as Figure 3 and Figure 5 As shown, the arc plate 23 and the arc-shaped pick plate 25 are rotated from the inclined state to the horizontal state, thereby releasing the simultaneous contact and connection of a set of symmetrical arc groove plates 22. When the arc-shaped pick plate 25 is moved, it is necessary to press the arc-shaped pick plate 25 downward to release the limit engagement of the arc-shaped pick plate 25, so that the arc-shaped pick plate 25 is forced to squeeze the multiple I-shaped elastic members 27 on the bottom end, thereby deforming it downward and disengaging from the pre-engaged plate groove 28. At the same time, the multiple rectangular blocks 26 are limited and slid downward in the corresponding rectangular grooves 24, thereby separating the fixed connection between the connecting plate 13 and the abutting plate 21, achieving the effect of quick disassembly.

[0023] The two second clamping structures each include a groove cylinder plate 230 fixedly connected to the rod body of the support rod 29, and the top inner wall of the groove cylinder plate 230 can be fitted and slidably connected with an inclined groove block 231, and the central bottom end of the inclined groove block 231 is fixedly connected to a double-headed arc column 232, and the double-headed arc column 232 and the inner wall of the groove cylinder plate 230 are fitted and slidably connected, and the two ends of the groove cylinder plate 230 near the top are penetrated and slidably connected with an inclined end rod 233, and the inclined end rods 233 have one end of the rod body that fits and connects with the outer wall of the double-headed arc column 232 near the top, and the two inclined end rods 233 are provided with an arc groove 234 on one side of the rod body near the double-headed arc column 232, and the inclined groove block 231 and the inner wall of the two arc grooves 234 can be intermittently fitted and clamped, and the bottom plate of one side of the plate frame 14 is fixedly connected to the top outer wall of the inclined groove block 231; The two oblique end rods 233 are fixedly connected to a hollow disk 235 on the side of the rod body away from the double-headed arc column 232, and a spring 236 is fixedly connected between the outer wall of one end of the two hollow disks 235 and the outer walls of both ends of the grooved drum plate 230. Two double-headed sleeve rods 237 are fixedly connected to the rod body of the support rod 29, and the inner walls on the other side of the two double-headed sleeve rods 237 are respectively fitted and slidably connected to the rod bodies of the two oblique end rods 233.

[0024] The above scheme is adopted: the pesticide storage tank 12 is lifted up, and the plate frame 14 that is forced to move upward will synchronously drive the inclined slot block 231 to move upward, and the upward movement of the inclined slot block 231 will drive the connected double-headed arc column 232 to move upward together, thereby pushing the two inclined end rods 233 that are attached to it to move in opposite directions. The inclined end rod 233 that is passively limited and translated in the groove drum plate 230 will be squeezed by the force and deformed by the spring 236 fixed to the outer wall of the groove drum plate 230, and then the spring can be used to The elastic force of 236 drives the oblique end rod 233 to reset, so as to facilitate the next re-engagement between the oblique groove block 231 and the two arc grooves 234, until the oblique groove block 231 and the double-headed arc column 232 are completely separated in the groove barrel plate 230, thereby the second layer of fixed connection can be quickly disassembled by simply moving upward. The above-mentioned loading and unloading means between the plant protection drone 1 and the pesticide storage tank 12 are fast and simple, easy to operate, ensure the stability of the connection, and can also be disassembled efficiently.

[0025] The working principle and use process of the present invention are as follows: when the pesticide storage tank 12 placed below the plant protection drone 1 is disassembled, the operator manually moves the arc-shaped dial plate 25 on the arc groove plate 22, so that it drives the arc panel 23 connected by multiple rectangular blocks 26 to rotate together. The rotating arc-shaped dial plate 25 also drives the multiple I-shaped elastic members 27 connected to the bottom end to perform limited sliding, so that the pesticide storage tank 12 can be disassembled by rotating, such as Figure 3 and Figure 5As shown, the arc plate 23 and the arc-shaped pick plate 25 are rotated from the inclined state to the horizontal state, thereby releasing the simultaneous contact and connection of a set of symmetrical arc groove plates 22. When the arc-shaped pick plate 25 is moved, it is necessary to press the arc-shaped pick plate 25 downward to release the limit engagement of the arc-shaped pick plate 25, so that the arc-shaped pick plate 25 is forced to squeeze the multiple I-shaped elastic members 27 on the bottom end, thereby causing it to deform and move downward, disengaging from the previously engaged plate groove 28. At the same time, the multiple rectangular blocks 26 are limited and slide downward in the corresponding rectangular grooves 24, thereby separating the fixed connection between the connecting plate 13 and the abutting plate 21, achieving the effect of quick disassembly. After the first layer of fixing means is disassembled, the pesticide storage tank 12 can be lifted up accordingly, and the upwardly moved support plate frame 14 will simultaneously drive the inclined slot block 231 to move up, and the upward movement of the inclined slot block 231 will drive the connected double-headed arc column 232 to move up together, thereby pushing the two inclined end rods 233 attached to it to move in opposite directions. The inclined end rod 233, which is passively limited and translated in the groove drum plate 230, will be forced to squeeze and deform the spring 236 fixed to the outer wall of the groove drum plate 230. Subsequently, the elastic force of the spring 236 itself can drive the inclined end rod 233 to reset, facilitating the next re-engagement between the inclined slot block 231 and the two arc-surface slots 234, until the inclined slot block 231 and the double-headed arc column 232 are completely separated in the groove drum plate 230, thereby quickly removing the second layer of fixing by simply moving upward.
