[0009] In one embodiment, the rotating component includes a toggle lever, one end of which is hinged to the lifting plate below the rotating column at the end of the rectangular slot frame. The end of the toggle lever away from the lifting plate is provided with a fastening buckle. Sliding guide rails are provided on opposite sides of the two sets of rectangular slot frames. A sliding rack is provided on the sliding guide rail. An auxiliary fastening lever is provided in the middle of the sliding rack. The auxiliary fastening lever fastens the fastening buckle of the toggle lever. A rotating gear is provided on the rotating column. The sliding rack meshes with the adjacent rotating gear during the guided movement of the sliding guide rail.

[0010] In one embodiment, a negative pressure mechanism is provided in the middle of the outer box. The negative pressure mechanism is used to extract air from the gap between the water storage tank and the outer box. The negative pressure mechanism includes a connecting pipe that is threaded to the outer box. An end baffle is provided at the end of the connecting pipe in the inner cavity of the outer box. A sealing funnel is provided in the middle of the connecting pipe. The conical opening of the sealing funnel faces the inner cavity of the outer box. A connecting pin is provided on the sealing funnel. The connecting pin passes through and is slidably connected to the end baffle before connecting to the sealing funnel. A thrust spring is provided between the sealing funnel and the end baffle, which is penetrated by the connecting pin.

[0011] In one embodiment, the connecting pipe is further provided with a power component, the power component including a rotating ring rotatably connected to the end of the connecting pipe, the rotating ring having a plurality of blades, the inner cavity of the rotating ring having a sliding block, the outer side of the sliding block having a wave groove, the inner cavity of the rotating ring having a push protrusion, the push protrusion passing through and slidably connected to the wave groove, a sliding plate being provided between the sealing funnel and the sliding block, an extension rod being provided between the sliding plate and the sliding block, and an air guide for one-way air leakage from the sealing funnel to the sliding block being provided on the sliding plate.

[0014] In one embodiment, the length of the sliding pin is greater than the thickness of the vent.

[0015] The beneficial effects of this invention are as follows: This invention is an agricultural drone that can quickly replenish liquids and automatically replenish pesticides, avoiding waste of pesticide liquids and environmental pollution; the specific implementation method is as follows:

[0016] The operator first removes the top cover, pulls out the rectangular slot frame along the mounting guide rail, puts the required medicine into the hopper inside the rectangular slot frame, slides the sliding rack to the top of the lever, then stands the lever upright and keeps it vertical, and then places the top cover on the outer box so that the buckle on the lever engages with the auxiliary buckle on the sliding rack, completing the initial operation;

[0017] Continue by removing the sealed water inlet on the top cover, then pour water into the water tank, and then fasten the sealed water inlet to seal the water tank. Next, rotate the blade to drive the agitator spray system to move along the wave groove in the sliding block, further driving the sliding block to slide back and forth within the rotating ring. As the sliding block slides away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, further driving the air in the outer box to flow into the space between the sealing funnel and the sliding plate through the gap in the sealing funnel. As the sliding plate approaches the sealing funnel, the air is compressed and first expands the sealing funnel to abut against the connecting pipe to seal the outer box. When the rotating ring is stationary, it is also in a sealed state, and by pushing the movable baffle away from the fixed plate, it creates a gap and flows out to the space between the rotating ring and the sliding block, completing the exhaust.

[0018] During the exhaust process, the pressure inside the outer box decreases, causing the lifting plate to move closer to the top cover in order to balance the pressure. As it moves closer to the top cover, the actuating rod pushes the sliding rack to slide, causing the rotating gear on the rotating column that is meshed with the sliding rack to rotate. This causes the receiving hopper to drop the medicine into the bottom of the outer box. At the same time, due to the movement of the lifting plate, the liquid above also falls into the bottom of the outer box. The two are mixed and can then begin operation.

[0019] During operation, the drone moves the outer tank while simultaneously driving the pump on the spraying system to discharge the liquid medicine from the outer tank to the nozzle through the water intake pipe, thus completing the spraying. At the same time, due to the consumption of liquid medicine, the lifting plate continues to move in order to further balance the pressure, which in turn drives the sliding guide rail to slide, realizing the automatic replenishment of medicine and liquid medicine during the spraying process. Once the spraying stops, no more liquid medicine medicine needs to be replenished, and the remaining amount of liquid medicine is small and easy to handle.

[0020] To expedite medication and fluid replacement, the drone can be lowered after the liquid in the outer casing attached to the drone has drained. This causes the outer casing to contact the bottom, raising the snap-fit ​​plate. The bending rod then rotates along the rotating connecting rod on the connecting frame, disengaging the snap-fit ​​plate from the outer casing. The drone can then be moved to a new outer casing and the process repeated in reverse to replace the outer casing and achieve rapid medication and fluid replacement.

[0021] The device has a simple structure and automatically replenishes the medicine and liquid by creating negative pressure in the tank through the use of liquid medicine. At the same time, different outer tanks can be quickly replaced. It has good stability and practicality, which is beneficial to the promotion and use of the equipment. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] The following is combined with Figure 1-7 The following describes a specific embodiment of the present invention: an automatic pesticide-replenishing agricultural drone, comprising a drone body, which is a general-purpose agricultural drone, with a water tank installed in its middle for spraying pesticides. This is prior art and not part of the invention, so it will not be described in detail. The drone body is equipped with a spraying system, which mainly consists of nozzles and a pump. The connecting frame on the drone body is equipped with a mounting device for pesticide replenishment. Furthermore, the mounting device includes two sets of fastening plates, which abut against the outer periphery of the outer box. Bent rods are provided below both ends of the fastening plates. The end of the bent rod away from the fastening plate extends outward away from the outer box. A rotating connecting rod is provided at the end of the bent rod away from the fastening plate, and the rotating connecting rod is rotatably connected to the connecting frame on the drone body.

[0034] In practice, after the liquid in the outer box attached to the drone body has drained, the drone body can be lowered so that the outer box contacts the bottom surface, causing the fastening plate to rise. This causes the bending rod to rotate along the rotating connecting rod on the connecting frame, causing the fastening plate to disengage from the outer box. Then, the drone body is moved to the top of the newly loaded outer box, and the above operation is repeated in reverse to replace the outer box and achieve rapid replenishment of liquid and medicine.

[0035] The medicine dispensing mechanism includes an outer box with a top cover and a sealed water inlet. Inside the outer box is a water storage tank supported by piles at the bottom. A water intake pipe for the sprinkler system enters between the outer box and the bottom plate of the water storage tank. A lifting plate is located inside the water storage tank, and a vent pipe connects the lifting plate and the water storage tank, extending through the outer box. A medicine dispensing device is located between the top cover near the side of the water storage tank and the inner cavity of the outer box to evenly dispense the medicine. This device includes two sets of L-shaped mounting rails symmetrically arranged on... On the inner cavity side of the top cover near the outer box, there is a rectangular groove frame in the middle of the mounting guide rail. There are guide rail connecting plates on both sides of the rectangular groove frame. The guide rail connecting plates are fastened to the adjacent mounting guide rails, so that the rectangular groove frame abuts against the top cover. The inner cavity of the rectangular groove frame has several material receiving hoppers, which are box structures with cavities. The material receiving hoppers are arranged in a straight line array in the inner cavity of the rectangular groove frame. There are rotating columns on both sides of the material receiving hoppers. The rotating columns pass through and are rotatably connected to the rectangular groove frame. There are rotating parts on the rotating columns to drive the rotating columns to rotate. Specifically, the inner cavity opening of the rectangular groove frame faces the space between the water storage tank and the outer box.

[0036] Beneficially, the rotating component includes a toggle lever, one end of which is hinged to a lifting plate below a rotating column at the end of a rectangular slot frame. The end of the toggle lever away from the lifting plate is provided with a latching buckle. Sliding guide rails are provided on opposite sides of the two sets of rectangular slot frames. A sliding rack is provided on the sliding guide rails. An auxiliary latching rod is provided in the middle of the sliding rack. The auxiliary latching rod latches onto the latching buckle of the toggle lever. A rotating gear is provided on the rotating column. During the guided movement of the sliding rack along the sliding guide rails, the sliding rack meshes with the adjacent rotating gear.

[0037] In practice, the pressure inside the outer box decreases, causing the lifting plate to move closer to the top cover in order to balance the pressure. As it moves closer to the top cover, the actuating rod pushes the sliding rack to slide, causing the rotating gear on the nearby rotating column to rotate. This causes the receiving hopper to drop the medicine into the bottom of the outer box. At the same time, due to the movement of the lifting plate, the liquid above also falls into the bottom of the outer box, and the two are mixed.

[0038] Beneficially, a negative pressure mechanism is provided in the middle of the outer tank. This mechanism is used to extract air from the gap between the water storage tank and the outer tank. The negative pressure mechanism includes a connecting pipe threaded to the outer tank. An end baffle is provided at the end of the connecting pipe within the inner cavity of the outer tank. A sealing funnel is provided in the middle of the connecting pipe, with its conical opening facing the inner cavity of the outer tank. A connecting pin is provided on the sealing funnel, passing through and slidingly connected to the end baffle before connecting to the sealing funnel. A thrust spring, penetrated by the connecting pin, is provided between the sealing funnel and the end baffle. The device is also equipped with a power component, which includes a rotating ring rotatably connected to the end of the connecting pipe. The rotating ring has several blades, and further, the number of blades is an odd number greater than two. The inner cavity of the rotating ring is equipped with a sliding block, and the outer side of the sliding block is equipped with a wave groove. The inner cavity of the rotating ring is equipped with a push-pull protrusion, which passes through and is slidably connected to the wave groove. A sliding plate is provided between the sealing funnel and the sliding block, and an extension rod is provided between the sliding plate and the sliding block. The sliding plate is equipped with a venting guide for one-way venting from the sealing funnel to the sliding block.

[0039] Beneficially, the air guide includes a movable baffle, a vent hole in the middle of the sliding plate, the movable baffle being inserted into and abutting against the movable baffle, a fixed plate on the side of the movable baffle near the sealing funnel, the fixed plate abutting against the inner side of the vent hole, a sliding pin in the middle of the movable baffle, the tip of the sliding pin being inserted into and slidably connected to the fixed plate and then connected to the movable baffle, and further, the length of the sliding pin is greater than the thickness of the vent hole.

[0040] In practice, rotating the blades drives the actuating spray system along the wave groove in the sliding block, further causing the sliding block to slide back and forth within the rotating ring. As the sliding block moves away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, further drawing air from the outer box into the space between the sealing funnel and the sliding plate. As the sliding plate approaches the sealing funnel, the air is compressed, first expanding the sealing funnel to seal the outer box against the connecting pipe. When the rotating ring is stationary, it is also in a sealed state, and by pushing the movable baffle away from the fixed plate, it creates a gap and flows out between the rotating ring and the sliding block, completing the exhaust.

[0041] Working principle of this invention:

[0042] In the initial state, the operator first removes the top cover, pulls out the rectangular slot frame along the mounting guide rail, puts the required medicine into the material receiving hopper inside the rectangular slot frame, slides the sliding rack to the top of the lever, then stands the lever upright and keeps it vertical, and then places the top cover on the outer box so that the buckle on the lever engages with the auxiliary buckle on the sliding rack, completing the initial operation;

[0043] Continue by removing the sealed water inlet on the top cover, then pour water into the water tank, and then fasten the sealed water inlet to seal the water tank. Next, rotate the blade to drive the agitator spray system to move along the wave groove in the sliding block, further driving the sliding block to slide back and forth within the rotating ring. As the sliding block slides away from the outer box, the extension rod on the sliding block drives the sliding plate away from the outer box, further driving the air in the outer box to flow into the space between the sealing funnel and the sliding plate through the gap in the sealing funnel. As the sliding plate approaches the sealing funnel, the air is compressed and first expands the sealing funnel to abut against the connecting pipe to seal the outer box. When the rotating ring is stationary, it is also in a sealed state, and by pushing the movable baffle away from the fixed plate, it creates a gap and flows out to the space between the rotating ring and the sliding block, completing the exhaust.

[0044] During the exhaust process, the pressure inside the outer box decreases, causing the lifting plate to move closer to the top cover in order to balance the pressure. As it moves closer to the top cover, the actuating rod pushes the sliding rack to slide, causing the rotating gear on the rotating column that is meshed with the sliding rack to rotate. This causes the receiving hopper to drop the medicine into the bottom of the outer box. At the same time, due to the movement of the lifting plate, the liquid above also falls into the bottom of the outer box. The two are mixed and can then begin operation.

[0045] During operation, the drone moves the outer tank while simultaneously driving the pump on the spraying system to discharge the liquid medicine from the outer tank to the nozzle through the water intake pipe, thus completing the spraying. At the same time, due to the consumption of liquid medicine, the lifting plate continues to move in order to further balance the pressure, which in turn drives the sliding guide rail to slide, realizing the automatic replenishment of medicine and liquid medicine during the spraying process. Once the spraying stops, no more liquid medicine medicine needs to be replenished, and the remaining amount of liquid medicine is small and easy to handle.

[0046] To expedite medication and fluid replacement, the drone can be lowered after the liquid in the outer casing attached to the drone has drained. This causes the outer casing to contact the bottom, raising the snap-fit ​​plate. The bending rod then rotates along the rotating connecting rod on the connecting frame, disengaging the snap-fit ​​plate from the outer casing. The drone can then be moved to a new outer casing and the process repeated in reverse to replace the outer casing and achieve rapid medication and fluid replacement.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.
