Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of agricultural drones, and particularly to an anti-vibration medicine storage box for agricultural drones. Background Art
[0002] With the rapid development of precision agriculture technology, agricultural drones are increasingly widely used in plant protection operations, and their efficient and flexible spraying methods have significantly improved the automation level of agricultural production.
[0003] As the core component of the drone plant protection system, the design of the medicine storage box directly affects the spraying accuracy and flight stability.
[0004] Currently, mainstream medicine storage boxes are mostly installed at the bottom of the drone by rigid fixation or simple suspension methods. Although they can meet the basic spraying requirements, in actual operations, multi-directional vibrations and impacts generated by the drone due to air flow disturbances, start-stop speed changes, and flying over complex terrains easily cause the medicine box to shake violently, which in turn leads to problems such as liquid medicine spilling, weight imbalance, and a decrease in spraying uniformity. When the drone suddenly stops or turns, the inertial impact of the liquid in the medicine box will exacerbate the body attitude fluctuations and reduce the flight control accuracy. In addition, traditional medicine storage boxes lack a dynamic attitude stabilization function. When the drone flies obliquely, the medicine box deflects accordingly, further exacerbating the liquid surface fluctuations and affecting the reliability and operation efficiency of the spraying system.
[0005] Therefore, it is necessary to design an anti-vibration medicine storage box for agricultural drones that can keep the medicine storage box always vertically downward during the flight of the drone to reduce the shaking of the liquid medicine and quickly restore the liquid medicine inside to a stable state when the drone suddenly stops or turns. Summary of the Invention
[0006] The present invention provides an anti-vibration medicine storage box for agricultural drones to solve the problems that in actual operations of existing devices, multi-directional vibrations and impacts generated by the drone due to air flow disturbances, start-stop speed changes, and flying over complex terrains easily cause the medicine box to shake violently, which in turn leads to problems such as liquid medicine spilling, weight imbalance, and a decrease in spraying uniformity. When the drone suddenly stops or turns, the inertial impact of the liquid in the medicine box will exacerbate the body attitude fluctuations and reduce the flight control accuracy. In addition, traditional medicine storage boxes lack a dynamic attitude stabilization function. When the drone flies obliquely, the medicine box deflects accordingly, further exacerbating the liquid surface fluctuations and affecting the reliability and operation efficiency of the spraying system.

The pushing bent rod contacts the lifting clamping frame, and the inner arc surface of the lifting clamping frame matches the outer arc surface of the fixed top frame.
[0010] Preferably, it further includes an auxiliary steady-state mechanism for quickly stabilizing the liquid medicine. The auxiliary steady-state mechanism includes a buoyancy plate, a connecting ring sleeve, a connecting rotating plate, a sliding sleeve, a stirring and stabilizing component and a clamping component. Buoyancy plates are symmetrically and slidably connected inside the medicine box. A connecting rotating plate is rotatably connected inside the medicine box. A sliding sleeve is slidably connected outside the connecting rotating plate. A connecting ring sleeve is slidably connected outside the sliding sleeve. Both ends of the connecting ring sleeve are fixedly connected to the corresponding buoyancy plate on one side. The stirring and stabilizing component is installed outside the sliding sleeve and is used to quickly restore the liquid medicine in the medicine box to a stable state. The clamping component is installed outside the connecting rotating plate and is used to limit the position of the sliding sleeve.
[0011] Preferably, the stirring and stabilizing component includes a ball, an inclined slideway and a stirring blade. The ball is rotatably connected inside the connecting ring sleeve. The inclined slideway is provided outside the sliding sleeve. The ball is located in the inclined slideway. The stirring blade is installed outside the sliding sleeve.
[0012] Preferably, the clamping component includes a sliding arc plate, a wedge-shaped clamping block and an unlocking component. Sliding arc plates are symmetrically and slidably connected to both sides of the connecting rotating plate. The wedge-shaped clamping block is installed inside the sliding arc plate. A wedge-shaped block is also fixedly connected to the top of the sliding sleeve. The wedge-shaped clamping block can limit the movement of the sliding sleeve through the wedge-shaped block at the top of the sliding sleeve. The unlocking component is installed on the sliding arc plate and is used to release the restriction on the sliding sleeve.
[0013] Preferably, the unlocking assembly includes a connecting spring and a toggling push rod. The sliding arc plate is connected to the connecting rotating plate through the connecting spring.

The lifting sliding plate is connected to the medicine box through the return spring.
[0016] Compared with the prior art, the present invention has the following advantages: 1. The buffer cushion plate absorbs high-frequency vibrations, while the shock-absorbing spring provides low-frequency buffering. The two work together to reduce the influence of vibrations in different frequency bands on the medicine box. Compared with a single shock-absorbing structure, this design can more effectively suppress compound vibrations, reduce the sloshing amplitude of the liquid medicine, improve the uniformity of pesticide application, and at the same time reduce the increase in energy consumption and structural fatigue of the drone caused by vibrations.
[0017] 2. No matter how the drone tilts, the medicine box always maintains a vertical posture, avoiding the spilling of the liquid medicine and the shift of the center of gravity caused by the tilted liquid surface. The center of gravity of the medicine box is stable, reducing the interference with the flight control system of the drone and improving the flight stability; the liquid surface remains stable, avoiding uneven spraying or overflow of the liquid medicine caused by tilting and sloshing, and improving the precision of pesticide application.
[0018] 3. Automatically adjust the limit state during the acceleration and deceleration stages of the drone to avoid violent swinging of the medicine box due to inertia. This mechanism allows the medicine box to make small adjustments during flight and gradually locks during deceleration, avoiding structural stress concentration caused by instantaneous impact and ensuring the stability of the drone during flight.
[0019] 4. When the liquid medicine sloshes, the floating plate is restricted in its up and down movement range by the sliding sleeve, enabling the floating plate to press the liquid medicine from the top to reduce the sloshing amplitude of the liquid medicine. During the up and down movement of the floating plate, it can drive the sliding sleeve to rotate at the same time. The ball moves along the inclined slideway, driving the stirring blade to generate turbulence, accelerating the stabilization of the liquid medicine and suppressing the liquid surface fluctuation; it is effective for high-viscosity liquid medicine or easily precipitated medicine powder, preventing sedimentation or stratification.
[0020] 5. During the sloshing process of the liquid medicine, the sliding sleeve and the connecting rotating plate rotate, and then drive the convex block to rotate through the arc-shaped rod. During the rotation of the convex block, it cooperates with the return spring to continuously jolt the lifting sliding plate up and down to push the medicine powder settled at the bottom of the medicine box upward, and at the same time cooperate with the stirring blade to quickly dissolve the undissolved medicine powder in water.

DETAILED DESCRIPTION
[0030] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.
[0031] Embodiment 1: An anti-vibration medicine storage box for agricultural drones, such as Figures 1 - 8As shown in the figure, it includes a fixing plate 1, a buffer backing plate 101, a shock-absorbing plate 102, a shock-absorbing spring 1021, a connecting frame 103, a medicine box 2, a medicine adding port 201, a steady-state mechanism and a limiting mechanism. The fixing plate 1 is fixed to the bottom of the drone by bolts. A buffer backing plate 101 is installed between the fixing plate 1 and the drone. The buffer backing plate 101 is made of an elastic material. A shock-absorbing plate 102 is slidably connected to the fixing plate 1. The shock-absorbing plate 102 is connected to the fixing plate 1 through a shock-absorbing spring 1021. Both ends of the shock-absorbing spring 1021 are respectively fixed to the shock-absorbing plate 102 and the fixing plate 1. Both the shock-absorbing spring 1021 and the buffer backing plate 101 can absorb the vibrations generated during the flight of the drone. A connecting frame 103 is fixedly connected to the bottom of the shock-absorbing plate 102. The connecting frame 103 is installed with a medicine box 2 through a steady-state mechanism. Medicine adding ports 201 are opened on both sides of the medicine box 2. The steady-state mechanism can keep the medicine box 2 in a vertical state. The limiting mechanism is installed on the shock-absorbing plate 102. During the deceleration of the drone, the limiting mechanism can limit the medicine box 2 to prevent the medicine box 2 and the liquid medicine inside from shaking violently due to inertia.
[0032] Threaded holes are opened on the fixing plate 1. The fixing plate 1 is fixedly connected to the bottom bracket of the drone by bolts. When the drone is flying, the shock-absorbing plate 102, the connecting frame 103 and the medicine box 2 are lifted through the fixing plate 1. The liquid medicine in the medicine box 2 sprays out from the spraying port at its bottom. The vibrations generated during the flight of the drone will be alleviated by the buffer backing plate 101 and the shock-absorbing spring 1021, so as to prevent the liquid medicine in the medicine box 2 from being affected and shaking. During the process of the drone driving the medicine box 2 to fly, no matter what attitude the drone flies in, the steady-state mechanism will keep the medicine box 2 in a vertically downward state all the time. During the flight of the drone, the limiting mechanism will release the restriction on the medicine box 2 under the action of air resistance. When the flight speed of the drone slows down, the limiting mechanism automatically resets due to the decrease in air resistance. During the reset process of the limiting mechanism, the medicine box 2 will be stuck again to prevent the medicine box 2 and the liquid medicine from shaking violently due to inertia and avoid the drone losing balance due to the influence of the medicine box 2. The buffer backing plate 101 absorbs high-frequency vibrations, while the shock-absorbing spring 1021 provides low-frequency buffering. The two work together to reduce the influence of vibrations in different frequency bands on the medicine box. Compared with a single shock-absorbing structure, this design can more effectively suppress composite vibrations, reduce the shaking amplitude of the liquid medicine, improve the uniformity of pesticide application, and at the same time reduce the increase in energy consumption and structural fatigue of the drone caused by vibrations.
[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figure 3As shown, the steady-state mechanism includes a connecting ball 104, a fixed top frame 105, and a connecting sleeve 106. A connecting ball 104 is fixedly connected to the bottom of the connecting frame 103, and a fixed top frame 105 is fixedly connected to the top of the medicine box 2. A connecting sleeve 106 is installed inside the fixed top frame 105. The connecting sleeve 106 is slidably sleeved on the outside of the connecting ball 104. During the flight of the drone, under the action of the connecting sleeve 106, the fixed top frame 105 and the medicine box 2 can always maintain a vertically downward state; it also includes a counterweight 2001, and the counterweight 2001 is fixedly connected to the bottom of the medicine box 2. Under the action of the counterweight 2001, the medicine box 2 can always maintain a vertically downward state.
[0034] Since the drone will tilt slightly in the flight direction during flight, and since the medicine box 2 and the connecting frame 103 are connected through the connecting ball 104, the fixed top frame 105, and the connecting sleeve 106, the medicine box 2 can rotate freely on the surface of the connecting ball 104 through the connecting sleeve 106. Under the influence of the gravity of the medicine box 2, the liquid medicine, and the counterweight 2001, the medicine box 2 always maintains a vertically downward state to avoid the reciprocating shaking of the medicine box 2 and prevent the drone from losing balance due to the influence of the medicine box 2. No matter how the drone tilts, the medicine box 2 always maintains a vertical posture, avoiding the spilling of the liquid medicine and the shift of the center of gravity caused by the tilted liquid surface. The center of gravity of the medicine box 2 is stable, reducing the interference with the flight control system of the drone and improving the flight stability; the liquid surface remains stable, avoiding uneven spraying or overflow of the liquid medicine caused by tilting and shaking, and improving the precision of pesticide application.
[0035] As Figure 3 shown, the limiting mechanism includes a wind plate 3, a return spring 301, a pushing bent rod 302, a lifting clamping frame 303, and a clamping spring 304. The wind plate 3 is slidably connected to the shock-absorbing plate 102. The wind plate 3 and the shock-absorbing plate 102 are connected through the return spring 301. One end of the return spring 301 is fixed on the wind plate 3, and the other end is fixed on the shock-absorbing plate 102. A pushing bent rod 302 is fixedly connected to the wind plate 3. The lifting clamping frame 303 is slidably connected to the bottom of the shock-absorbing plate 102. The lifting clamping frame 303 and the shock-absorbing plate 102 are connected through the clamping spring 304. One end of the clamping spring 304 is fixed on the shock-absorbing plate 102, and the other end is fixed on the lifting clamping frame 303. The pushing bent rod 302 contacts the lifting clamping frame 303, and the inner arc surface of the lifting clamping frame 303 matches the outer arc surface of the fixed top frame 105.
[0036] In the initial state, the wind plate 3 and the return spring 301 are in place. During the flight of the drone, the wind plate 3 slides towards the shock absorbing plate 102 due to the air resistance, and the return spring 301 is compressed. When the wind plate 3 approaches the shock absorbing plate 102, pushing the bent rod 302 will push the lifting and locking frame 303 to slide upward along the shock absorbing plate 102, and the locking spring 304 will be compressed at the same time. After the lifting and locking frame 303 rises to a high position, it will be out of contact with the fixed top frame 105. At this time, the fixed top frame 105 is no longer restricted, and the connecting sleeve 106 can slide outside the connecting ball 104. During the deceleration of the drone, the wind plate The air resistance of the air box 3 is reduced, and the return spring 301 pushes the air plate 3 to slide and return to the direction away from the shock absorbing plate 102, pushing the bent rod 302 to return to its original position, and the locking spring 304 pushes the lifting and lowering locking frame 303 to slide and return to its original position, and then locks it outside the fixed top frame 105 again, so as to restrict the medicine box 2 through the fixed top frame 105 again, and automatically adjust the limit state during the acceleration and deceleration stage of the UAV to avoid the medicine box 2 from swinging violently due to inertia. The mechanism allows the medicine box 2 to be slightly adjusted during flight, and gradually locked during deceleration, so as to avoid the structural stress concentration caused by instantaneous impact, and ensure the stability of the UAV during flight.
[0037] Embodiment 3: Based on embodiment 2, Figures 4 - 8 As shown, it also includes an auxiliary stabilization mechanism for quickly and steadily restoring the medicine liquid, the auxiliary stabilization mechanism includes a buoyancy plate 4, a connecting ring sleeve 401, a connecting rotating plate 402, a sliding sleeve 406, a stirring and stabilizing component and a locking component, the buoyancy plate 4 is symmetrically slidably connected inside the medicine box 2, the connecting rotating plate 402 is rotatably connected inside the medicine box 2, the sliding sleeve 406 is slidably connected outside the connecting rotating plate 402, the sliding sleeve 406 is slidably connected outside the sliding sleeve 406, the connecting ring sleeve 401 is slidably connected outside the sliding sleeve 406, the two ends of the connecting ring sleeve 401 are respectively fixedly connected to the buoyancy plate 4 on the corresponding side, the stirring and stabilizing component is installed outside the sliding sleeve 406, the stirring and stabilizing component is used to quickly restore the medicine liquid in the medicine box 2 to stability, the locking component is installed outside the connecting rotating plate 402, and the locking component is used to limit the position of the sliding sleeve 406.
[0038] like Figure 6 and Figure 7 As shown, the stirring and stabilizing component includes a ball 4011, an inclined slide 4061 and a stirring blade 407. The ball 4011 is rotatably connected inside the connecting ring sleeve 401, the inclined slide 4061 is opened outside the sliding sleeve 406, the ball 4011 is located inside the inclined slide 4061, and the stirring blade 407 is installed outside the sliding sleeve 406. The sliding sleeve 406 can drive the stirring blade 407 to rotate, so that the medicine liquid in the medicine box 2 can be quickly and steadily moved.
[0039] When the medicine box 2 is full of liquid medicine, the buoyancy board 4 is affected by the buoyancy of the liquid medicine and slides to the top of the medicine box 2. As the liquid medicine is continuously sprayed outward, the buoyancy board 4 and the sliding sleeve 406 always descend synchronously with the liquid medicine along the connecting rotating plate 402. When the flight speed of the drone decreases, the medicine box 2 can be restricted, but the liquid medicine inside it will still be affected by inertia and shake in the medicine box 2. Under the restriction of the buoyancy board 4, the shaking amplitude of the liquid medicine will be greatly reduced, and in the process of the liquid medicine shaking, the buoyancy board 4 is pushed to move up and down continuously along the sliding sleeve 406. In the process of the buoyancy board 4 moving up and down, under the action of the ball 4011 and the inclined slide 4061, the sliding sleeve 406 and the connecting rotating plate 40 2 is driven to rotate, and the stirring blade 407 rotates accordingly. During the rotation of the stirring blade 407 in the liquid medicine, shear turbulence can be generated in the liquid medicine, so that the kinetic energy of the shaking is quickly consumed, so that the liquid medicine quickly returns to a stable state; when the liquid medicine shakes, the buoyancy plate 4 is limited by the sliding sleeve 406 in the up and down movement range, so that the buoyancy plate 4 can press the liquid medicine from the top to reduce the shaking amplitude of the liquid medicine, and the buoyancy plate 4 can simultaneously drive the sliding sleeve 406 to rotate during the up and down movement, and the ball 4011 moves along the inclined slide 4061, driving the stirring blade 407 to generate turbulence, accelerating the stability of the liquid medicine, and suppressing the fluctuation of the liquid surface; it is effective for high-viscosity liquid medicine or easy-to-precipitate powder to prevent deposition or stratification.
[0040] like Figure 5 and Figure 8 As shown, the locking assembly includes a sliding arc plate 403, a wedge-shaped block 4031 and an unlocking assembly. The sliding arc plate 403 is symmetrically connected to the sliding on both sides of the connecting rotating plate 402. The wedge-shaped block 4031 is installed in the sliding arc plate 403. The top of the sliding sleeve 406 is also fixed with a wedge block. The wedge-shaped block 4031 can limit its movement through the wedge block on the top of the sliding sleeve 406. The unlocking assembly is installed on the sliding arc plate 403, and the unlocking assembly is used to release the restriction on the sliding sleeve 406.
[0041] like Figure 5 and Figure 8 As shown, the unlocking assembly includes a connecting spring 404 and a toggle push rod 405. The sliding arc plate 403 and the connecting rotating plate 402 are connected via the connecting spring 404. One end of the connecting spring 404 is fixed on the sliding arc plate 403, and the other end is fixed on the connecting rotating plate 402. The sliding arc plate 403 is fixedly connected with a toggle push rod 405. The top of the toggle push rod 405 passes through the medicine box 2, and the toggle push rod 405 can slide along the medicine box 2.
[0042] During the process of the sliding sleeve 406 descending along the connecting rotating plate 402, the wedge-shaped block at the top of the sliding sleeve 406 continuously pushes the sliding arc plate 403 to slide along the connecting rotating plate 402 through the wedge-shaped block 4031. When the sliding sleeve 406 is out of contact with the wedge-shaped block 4031, the sliding arc plate 403 can slide back along the connecting rotating plate 402 under the push of the connecting spring 404, thereby causing the wedge-shaped block 4031 to restrict it from the top of the sliding sleeve 406. After the spraying of the liquid medicine is completed, the sliding sleeve 406 descends to the lowest point along the connecting rotating plate 402, and the drone flies back and re-adds liquid medicine into the medicine box 2. At this time, the two sliding arc plates 403 are pushed closer to each other by toggling the push rod 405, so that the wedge-shaped block 4031 is out of contact with the sliding sleeve 406. At this time, under the action of the buoyancy of the liquid medicine, the buoyancy plate 4, the connecting ring sleeve 401, the sliding sleeve 406 and other components will slide upward and return to their original position along the connecting rotating plate 402.
[0043] like Figure 5 and Figure 8 As shown, it also includes a throwing lifting component for pushing the powder at the bottom of the medicine box 2 upward, and the throwing lifting component includes an arc rod 4021, a protrusion 4022, a lifting slide 5 and a return spring 501. The bottom of the connecting rotating plate 402 is fixedly connected with the arc rod 4021, and the protrusion 4022 is fixedly connected to the arc rod 4021. The bottom of the medicine box 2 is slidably connected with the lifting slide 5, and the lifting slide 5 is connected to the medicine box 2 through the return spring 501. One end of the return spring 501 is fixed on the lifting slide 5, and the other end is fixed on the medicine box 2. During the rotation of the connecting rotating plate 402, the lifting slide 5 can be pushed to slide upward by the arc rod 4021 and the protrusion 4022, thereby throwing the powder at the bottom of the medicine box 2 upward.
[0044] The sliding sleeve 406 rotates and drives the connecting rotating plate 402 to rotate. The connecting rotating plate 402 rotates and drives the arc rod 4021 and the bump 4022 at the bottom to rotate. The bump 4022 rotates and drives the lifting slide plate 5 to rise along the medicine box 2 and compress the return spring 501. When the bump 4022 is out of contact with the lifting slide plate 5, the return spring 501 drives the lifting slide plate 5 to descend and reset. When the connecting rotating plate 402 drives the arc rod 4021 to rotate, the bump 4022 cooperates with the return spring 501 to The lifting slide plate 5 is continuously slid up and down to push the medicine powder deposited at the bottom of the medicine box 2 upward, and the medicine powder thrown upward will quickly dissolve into the water under the stirring of the stirring rod; during the shaking of the medicine liquid, the sliding sleeve 406 and the connecting rotating plate 402 rotate, and then the protrusion 4022 is driven to rotate through the arc rod 4021. During the rotation of the protrusion 4022, it cooperates with the return spring 501 to make the lifting slide plate 5 continuously shake up and down to push the medicine powder settled at the bottom of the medicine box 2 upward, and at the same time cooperate with the stirring blade 407 to make the undissolved medicine powder quickly dissolve into the water.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
