Description

Technical Field

[0001] This utility model relates to the field of agricultural drones, specifically a multi-rotor drone pesticide atomization spraying device. Background Technology

[0002] Agricultural drones, also known as unmanned aerial vehicles (UAVs), are unmanned aircraft used for the protection of agricultural and forestry plants. These drones consist of three parts: a flight platform (fixed-wing, helicopter, or multi-rotor), navigation and flight control, and a spraying mechanism. They perform spraying operations via ground remote control or navigation and flight control, and can spray pesticides, seeds, and other substances. With the rapid development of drone technology, the more widely used "agricultural drones" are gradually replacing "plant protection drones." Agricultural drones are not only used for spraying pesticides but can also perform various tasks such as fertilizing, sowing seeds, and spreading feed, meeting the diverse needs of farmers and improving production efficiency.

[0003] Current multi-rotor drone pesticide atomizing spraying devices, as described in patent announcement number CN218112993U, include a fuselage, two sets of symmetrical arms mounted on the fuselage, and a power unit fixedly connected to the arms. The device is characterized by a detachable protective shell at the lower end of the fuselage, a pesticide tank inside the protective shell, several smaller pesticide tanks inside the pesticide tank, a spraying device on each pesticide tank, a drive unit on the protective shell to drive the spraying device, the smaller pesticide tanks being assembled inside the pesticide tank, a baffle plate inside each smaller pesticide tank, slots on each pesticide tank, and a protective door on the protective shell.

[0004] Regarding the aforementioned technologies, the inventors believe that the fact that the medicine tank is installed inside the protective shell makes disassembly inconvenient. Furthermore, once the medicine in the tank is used up and the aircraft returns to land, workers need to re-prepare the medicine inside the tank, resulting in a long waiting time before the pesticide can be sprayed again. This leads to low efficiency in spraying pesticides on crops. Utility Model Content

[0005] The purpose of this invention is to provide a multi-rotor drone pesticide atomization spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-rotor drone pesticide atomizing spraying device, including

[0008] The docking mechanism includes a drone body, a liquid extraction tube fixedly connected to the bottom of the drone body, a horizontal tube fixedly connected to the bottom of the liquid extraction tube, a medicine tank located below the drone body, an L-shaped liquid tube fixedly inserted through the inside of the medicine tank, one end of the L-shaped liquid tube abutting against the horizontal tube, a guide block fixedly connected at the middle position inside the horizontal tube, a guide rod slidingly inserted through the inside of the guide block, rubber plugs fixedly connected to both ends of the guide rod, symmetrical retaining rings corresponding to the rubber plugs fixedly connected inside the horizontal tube, one side of the rubber plug abutting against the other side of the retaining ring, and a T-shaped push rod fixedly connected inside the L-shaped liquid tube, one end of the T-shaped push rod abutting against the other side of the rubber plug.

[0009] The limiting mechanism includes slide rails symmetrically and fixedly connected to the bottom of the drone body. Slider blocks are slidably connected to opposite sides of the slide rails. Both sets of sliders are fixedly connected to the medicine barrel. Circular grooves are opened on opposite sides of both sets of sliders. Guide grooves are opened on both sides of both sets of circular grooves. Rotary shafts are rotatably connected inside both sets of slide rails. Limiting rotating blocks that match the circular grooves are fixedly connected to opposite sides of both sets of rotating shafts. A feed port is fixedly connected to one side of the top of the medicine barrel.

[0010] As a further embodiment of this utility model: the bottom of the drone body is symmetrically and fixedly connected with a bracket, the medicine barrel is located between the two sets of L-shaped liquid pipes, and the bottom four corners of the medicine barrel are rotatably connected with rollers.

[0011] As a further embodiment of this utility model: reinforcing ribs are symmetrically fixedly connected to the opposite sides of the two sets of sliders, and each set of reinforcing ribs is fixedly connected to the medicine barrel.

[0012] As a further embodiment of this utility model: the top of the feed inlet is threaded with a threaded cap, and an air hole is provided on one side of the top of the medicine barrel.

[0013] As a further embodiment of this utility model: a rotating rod is fixedly connected to one end of each of the two sets of rotating shafts away from the limiting rotating block, and a torsion spring is fixedly connected between the two sets of rotating rods and the slide rail.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] With the above-described structure, this invention utilizes the interplay of an L-shaped liquid tube, guide rod, horizontal tube, T-shaped push rod, and limiting rotating block. When the limiting rotating block rotates to a horizontal position, the limiting of the slider can be released. Then, another pesticide tank containing pesticide can be removed, with the L-shaped liquid tube on the tank aligned with the other end of the horizontal tube. The other tank is then pushed towards the tank to be replaced, moving it below the drone body. The other tank moves below the drone body until the L-shaped liquid tube on the other tank abuts against the other end of the horizontal tube. Simultaneously, the T-shaped push rod inside the other L-shaped liquid tube pushes a rubber stopper on one side to press against a retaining ring on the other side, while the other rubber stopper disengages and abuts against the drone body. Afterward, simply rotating the limiting rotating block to misalign with the guide groove completes the replacement of the pesticide tank. This allows for easy replacement of the pesticide tank once the pesticide solution inside is depleted, effectively improving the spraying efficiency of pesticides. Attached Figure Description

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] Please see Figure 1-4 A multi-rotor drone pesticide atomizing spraying device includes a docking mechanism 1, which comprises a drone body 101. A liquid extraction pipe 104 is fixedly connected to the bottom of the drone body 101, and a horizontal pipe 105 is fixedly connected to the bottom of the liquid extraction pipe 104. The liquid extraction pipe 104 and the horizontal pipe 105 are configured to guide the pesticide flow. A pesticide tank 102 is located below the drone body 101, used to hold the pesticide. A feed inlet 203 is fixedly connected to one side of the top of the pesticide tank 102, facilitating the filling of pesticide solution into the tank. A threaded cap 204 is threadedly connected to the top of the feed inlet 203, used to close the feed inlet 203 and reduce the probability of debris entering the pesticide tank 102 from the inside of the feed inlet 203.

[0026] A vent 110 is provided on one side of the top of the medicine container 102. The vent 110 allows outside air to enter, thus maintaining a consistent pressure inside and outside the medicine container 102. A bracket 113 is symmetrically and fixedly connected to the bottom of the drone body 101. The medicine container 102 is located between two sets of L-shaped liquid tubes 103. The bracket 113 provides support and limits the movement of the medicine container 102. Rollers 112 are rotatably connected to the four corners of the bottom of the medicine container 102, facilitating movement and adjustment of the medicine container 102.

[0027] The limiting mechanism 2 includes a slide rail 201 symmetrically fixedly connected to the bottom of the drone body 101. Slider 202 is slidably connected to the opposite side of the slide rail 201. Both sets of sliders 202 are fixedly connected to the medicine barrel 102. The sliders 202 and the slide rail 201 can provide limiting support for the medicine barrel 102 and guide the movement of the medicine barrel 102.

[0028] Two sets of sliders 202 are symmetrically fixedly connected to opposite sides with reinforcing ribs 205. Each set of reinforcing ribs 205 is fixedly connected to the medicine barrel 102. The reinforcing ribs 205 are used to further connect and fix the sliders 202 and the medicine barrel 102, thereby improving the connection stability between the sliders 202 and the medicine barrel 102.

[0029] Both sets of sliders 202 have circular grooves 207 on their opposite sides, and guide grooves 206 are provided on both sides of the two sets of circular grooves 207. The interior of both sets of slide rails 201 is rotatably connected to a rotating shaft 208. The opposite sides of the two sets of rotating shafts 208 are fixedly connected to a limiting rotating block 209 that matches the circular groove 207. The rotating shaft 208 is designed to drive the limiting rotating block 209 to rotate when rotating, so that when the limiting rotating block 209 moves into the interior of the circular groove 207 and rotates to the point of being misaligned with the guide groove 206, it can limit the slider 202, thereby restricting the sliding of the slider 202 and thus fixing the medicine barrel 102. Two sets of rotating shafts 208 are fixedly connected to a rotating rod 211 at the end away from the limiting rotating block 209. A torsion spring 210 is fixedly connected between the two sets of rotating rods 211 and the slide rail 201. The rotating shafts 208 are designed to use their own elasticity to limit the rotation of the rotating rods 211, rotating shafts 208 and limiting rotating blocks 209, so as to reduce the probability that the limiting rotating block 209 rotates to the guide groove 206 for alignment.

[0030] Both sets of rotating rods 211 have stop bars 213 at their bottoms, and the two sets of stop bars 213 are fixedly connected to the two sets of slide rails 201 respectively. The stop bars 213 limit the rotation of the rotating rods 211. A lever 212 is fixedly connected to the opposite sides of both sets of rotating rods 211. A diagonal bar 214 corresponding to the lever 212 is symmetrically fixedly connected to the top of the medicine container 102 away from the diagonal bar 212. The diagonal bar 214 is used to move towards the diagonal bar 212 to push the diagonal bar 212 to slide along the diagonal bar 214, thereby driving the rotating rods 211, the rotating shaft 208, and the limiting rotating block 209 to rotate. This allows the medicine container 102 to be unlocked simply by pushing the other set of medicine containers 102 towards the medicine container 102 to be replaced.

[0031] An L-shaped liquid tube 103 is fixedly installed inside the pesticide tank 102. One end of the L-shaped liquid tube 103 abuts against a horizontal tube 105. The L-shaped liquid tube 103 is designed to connect with the horizontal tube 105, thereby guiding the pesticide inside the drone body 101 into the horizontal tube 105. A guide block 106 is fixedly connected to the middle of the horizontal tube 105. A guide rod 107 slides through the guide block 106, and the guide block 106 guides the sliding of the guide rod 107.

[0032] Both ends of the guide rod 107 are fixedly connected to rubber plugs 109. Symmetrically fixed inside the horizontal tube 105 are retaining rings 108 corresponding to the rubber plugs 109. The rubber plugs 109 are designed to move synchronously with the guide rod 107, allowing them to be sealed when they abut against the retaining rings 108. A side rubber plug 109 abuts against a side retaining ring 108. A T-shaped push rod 111 is fixedly connected inside the L-shaped liquid tube 103. One end of the T-shaped push rod 111 abuts against the other side rubber plug 109. The T-shaped push rod 111 is used to push the rubber plug 109 and guide rod 107 when the L-shaped liquid tube 103 connects to the horizontal tube 105, causing one side retaining ring 108 to open and the other side retaining ring 108 to be blocked.

[0033] In this embodiment, the main body 101 of the drone is existing technology and will not be described in detail here.

[0034] In use, the drone body 101 is activated, enabling it to carry the pesticide tank 102 into flight. After reaching the location where pesticides will be sprayed, the pump inside the drone body 101 draws pesticide liquid from the tank 102 through the suction pipe 104, horizontal pipe 105, and L-shaped liquid pipe 103, and then sprays it onto the crops. When the pesticide in the tank 102 is depleted, the drone body 101 returns and lands. Then, another tank 102 filled with pesticide is retrieved, and the two diagonal rods 214 on the other tank 102 are aligned with the two sets of levers 212. Then, the other medicine barrel 102 is pushed towards the bottom of the medicine barrel 102 to be replaced. As the inclined rod 214 continues to move towards the medicine barrel 102 to be replaced after contacting the two sets of levers 212, the levers 212 can slide along the top of the inclined rod 214, thereby driving the rotating rod 211 and the rotating shaft 208 to rotate. When the rotating shaft 208 rotates, it can drive the limiting rotating block 209 to rotate. When the limiting rotating block 209 rotates to the horizontal position, the two sets of medicine barrels 102 come into contact, and at the same time, the sliders 202 on the two sets of medicine barrels 102 also come into contact, so that when the other set of medicine barrels 102 continues to move, it can push the other... The side medicine tank 102 moves accordingly, causing the L-shaped liquid tube 103 on the medicine tank to be replaced detach from one end of the horizontal tube 105. At this time, the limiting block 209 slides along the guide groove 206. As the two sets of medicine tanks 102 move, it slides into the corresponding guide groove 206 on the other set of sliders 202. At the same time, the other set of sliders 202 engages with the slide rail 201. When the slider 202 on the medicine tank to be replaced detaches from the slide rail 201, the limiting block 209 slides into the corresponding circular groove 207 on the other set of medicine tanks 102. At this time, the torsion spring 210 returns to its deformation, thereby bringing... The rotating rod 211, the rotating shaft 208, and the limiting rotating block 209 rotate, causing the limiting rotating block 209 to rotate to be misaligned with the guide groove 206, thereby limiting the slider 202 and the other set of medicine barrels 102. At this time, the L-shaped liquid tube 103 on the other set of medicine barrels 102 moves to abut against the other end of the horizontal tube 105. At the same time, the T-shaped push rod 111 inside the L-shaped liquid tube 103 pushes the rubber plug 109 on the other side of the guide rod 107 to disengage from the other side and abut against the other side retaining ring 108, while the rubber plug 109 on one side moves to abut against the retaining ring 108 on the other side, thereby completing the replacement of the medicine barrel 102.

[0035] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
