Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically to a fixing mechanism for the pesticide box of an agricultural drone. Background Technology

[0002] Unmanned aerial vehicle (UAV) plant protection refers to the use of drones for the maintenance of agricultural and forestry plants. Drones used for plant protection, also known as agricultural drones, can use fixed-wing, single-rotor, or multi-rotor drones as flight platforms, with spraying mechanisms mounted on them. Spraying operations are achieved through ground remote control or GPS flight control, and can spray pesticides, seeds, powders, etc. Currently, the pesticide tanks of agricultural drones are generally clipped to the upper part of the drone frame or suspended from the lower part of the drone body, locked with bolts. While the connection structure is simple, the bolts are relatively scattered, making disassembly inconvenient during use.

[0003] To address the aforementioned issues, this application provides a fixing structure for the pesticide container of an agricultural drone, which improves the convenience and stability of connecting the pesticide container to the drone body. Utility Model Content

[0004] To solve the above problems, this utility model provides a fixing mechanism for the pesticide box of agricultural drones.

[0006] The connecting assembly includes several limiting arms, which form limiting slots with the main body of the medicine box. Several limiting pieces are provided at the bottom of the connecting column, and the limiting slots are used to accommodate the limiting pieces. The limiting arms and the connecting column are detachably connected.

[0007] As an optimization, the lower part of the connecting column is provided with several docking blocks, the docking blocks are provided with connecting grooves, and the end of the limiting arm opposite to the connecting column is movably provided with a limiting pin, and the connecting groove is used to accommodate the limiting pin.

[0008] The limiting arm has a lateral adjustment cavity inside, and a first tightening spring is installed inside the lateral adjustment cavity. One end of the limiting pin is connected to the first tightening spring.

[0009] As an optimization, a vertical adjustment cavity is provided on the upper part of the docking block, and a locking rod is provided inside the vertical adjustment cavity. The lower end of the locking rod can extend into the connecting groove.

The outer end of the limiting pin is a pointed tip, and a vertical limiting hole is provided at the end of the limiting pin that connects to the connecting groove. The limiting hole is used to accommodate the locking rod.

[0011] As an optimization, the middle part of the connecting column is provided with a connecting thread, the lower end of the connecting thread is adjacent to the mating block, and the connecting thread is connected to a locking sleeve. When the locking sleeve rotates downward, it can press the locking rod downward into the limiting hole.

[0012] As an optimization, a connecting ring is provided on the top of the medicine box body, the limiting arm is connected to the upper side of the connecting ring, and the limiting slot is located on the inner side of the connecting ring.

[0013] As an optimization, a carding inlet is formed between adjacent limiting arms. The limiting piece is fan-shaped and enters the limiting slot downward through the carding inlet. The limiting piece can be screwed into the lower side of the limiting arm by rotating the connecting column.

[0014] The beneficial effects of this plan are as follows:

[0015] This application sets a connecting column on the lower side of the drone body and a limiting arm on the top of the medicine box. The limiting arm connects the limiting plate and the connecting column in a double manner, and the connection between the drone body and the medicine box is reinforced by a locking sleeve.

It is used in conjunction with a motherboard, memory modules, storage media, and power supply, which is AC power or a lithium battery. When a display screen is provided, a graphics card is also included.

[0028] like Figures 1-9 As shown, the pesticide tank fixing mechanism for plant protection drones includes a drone body 1 and a pesticide tank body 2. A connecting post 3 is provided at the bottom of the drone body 1, and a connecting component is provided at the top of the pesticide tank body 2. The connecting post 3 and the connecting component are detachably connected.

[0029] The connecting assembly includes several limiting arms 4, and a limiting groove 6 is formed between the limiting arms 4 and the main body of the medicine box 2. Several limiting pieces 5 are provided at the bottom of the connecting column 3, and the limiting groove 6 is used to accommodate the limiting pieces 5. The limiting arms 4 and the connecting column 3 are detachably connected.

[0030] The upper and lower surfaces of the connecting piece can be made of frosted or silicone material to increase the friction between the connecting piece and the limiting groove 6, preventing relative movement between them. Meanwhile, the height of the limiting groove 6 should be equal to or slightly greater than the thickness of the connecting piece, allowing the connecting piece to snap into the limiting groove 6.

[0031] like Figure 8 As shown, the lower part of the connecting column 3 is provided with a plurality of docking blocks 7, the docking blocks 7 are provided with connecting grooves, and the end of the limiting arm 4 opposite to the connecting column 3 is movably provided with a limiting pin 8, and the connecting groove is used to accommodate the limiting pin 8.

[0032] The limiting arm 4 has a lateral adjustment cavity inside, and a first tightening spring 9 is installed inside the lateral adjustment cavity. One end of the limiting pin 8 is connected to the first tightening spring 9.

[0033] Under the action of the first tightening spring 9, the limiting pin 8 can remain in an outward extended state, and at the same time, the limiting pin 8 can also be retracted into the transverse adjustment cavity by force.

[0034] like Figure 8 and Figure 9 As shown, the upper part of the docking block 7 is provided with a vertical adjustment cavity, and a locking rod 10 is provided inside the vertical adjustment cavity. The lower end of the locking rod 10 can extend into the connecting groove.

[0035] A limiting ring 13 is provided in the middle of the locking rod 10. A second support spring 11 is provided between the limiting ring 13 and the bottom of the vertical adjustment cavity. The outer end of the limiting pin 8 is a pointed tip. A vertical limiting hole 14 is provided at one end of the limiting pin 8 that connects to the connecting groove. The limiting hole 14 is used to accommodate the locking rod 10.

[0036] The limiting hole 14 can be set through the locking rod 10, or it can be set as follows: Figure 9 The groove shown is sufficient to restrict the rotation of the limiting pin 8. Under the action of the second support spring 11, the locking rod 10 is in an upward-raised state, which does not affect the connection between the limiting pin 8 and the mating block 7.

[0037] like Figure 8 As shown, the middle part of the connecting column 3 is provided with a connecting thread, and the lower end of the connecting thread is adjacent to the mating block 7. The connecting thread is connected to a locking sleeve 12. When the locking sleeve 12 rotates downward, it can press the locking rod 10 downward into the limiting hole 14.

[0038] The locking sleeve 12 has anti-slip texture on its exterior to facilitate rotation of the locking sleeve 12.

[0039] like Figure 4 and Figure 8As shown, a connecting ring 15 is provided on the top of the medicine box body 2, the limiting arm 4 is connected to the upper side of the connecting ring 15, and the limiting slot 6 is located on the inner side of the connecting ring 15.

[0040] The connecting ring 15 and the limiting arm 4 can be fixed or integrally formed.

[0041] like Figure 4 As shown, an inlet is formed between adjacent limiting arms 4. The limiting piece 5 is fan-shaped. The limiting piece 5 enters the limiting slot 6 through the inlet. The limiting piece 5 can be screwed into the lower side of the limiting arm 4 by rotating the connecting column 3.

[0042] When using the device, first inject the mixed medicine into the main body 2 of the medicine box, and set the medicine box vertically upward;

[0043] The connecting column 3 of the drone body 1 is inserted from top to bottom between multiple limiting arms 4, so that the limiting piece 5 passes through the card slot downward and contacts the top of the medicine box body 2.

[0044] Rotate the main body 1 of the drone so that the limiting piece 5 is inserted into the limiting slot 6, and the limiting arm 4 limits the limiting piece 5.

[0045] When the limiting arm 4 is positioned opposite the docking block 7, the limiting pin 8 is engaged in the connecting groove;

[0046] Rotate the locking sleeve 12 from top to bottom, so that the locking sleeve 12 gradually moves downward and presses against the locking rod 10, so that the lower end of the locking rod 10 moves downward into the limiting hole 14, thereby limiting the position of the limiting pin 8.

[0047] After use, rotate the locking sleeve 12 upwards to remove the locking rod 10 from the limit hole 14.

[0048] Rotating the drone body 1 can cause the limiting plate 5 and the limiting arm 4 to be misaligned, making it easier to separate the drone body 1 from the medicine box body 2.

[0049] Since the outer end of the limiting pin 8 is a pointed tip, rotating the drone body 1 will cause the docking block 7 to squeeze the pointed tip of the limiting pin 8, causing the limiting pin 8 to retract into the lateral adjustment cavity, thus separating the drone body 1 from the medicine box body 2.

[0050] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any appropriate changes or modifications made by a person skilled in the art to the fixed mechanism for the pesticide box of an agricultural drone that conforms to the claims of this utility model should fall within the patent protection scope of this utility model.
