Description

Technical Field

[0001] This invention belongs to the field of submerged plant seeding technology, specifically a submerged plant seeding device and its seeding method. Background Technology

[0002] With increasing awareness of aquatic ecological restoration and environmental protection, the planting and restoration of submerged plants has become an important means to improve water quality and enhance the self-purification capacity of water bodies. However, traditional methods of submerged plant placement mostly rely on manual labor, which is not only inefficient but also difficult to accurately place in large areas, deep waters, or complex environmental conditions.

[0003] Therefore, developing a device that can efficiently, accurately, and safely sow submerged plants into designated water areas is of great significance for promoting the progress of aquatic ecological restoration.

[0004] The existing method of planting submerged plants generally involves pre-planting the plants in containers filled with potting soil and then placing the containers in the designated location. However, this method still requires manual labor, which necessitates manually navigating boats to the designated locations to place the plants one by one. This is especially problematic in shallow waters where boats are not feasible, requiring workers to place the plants in the water. This method is inefficient and carries certain risks. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a submerged plant seeding device and its seeding method. This submerged plant seeding device can rely on drones to fly to designated locations for rapid seeding, greatly improving seeding efficiency and safety.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a submerged plant planting device, comprising at least two drones and a storage box, wherein a sleeve is vertically installed at the bottom of the drone, a winding mechanism is installed at the top of the sleeve, a side bracket is fixed to the side of the storage box, and a suspension rope on the winding mechanism passes through the sleeve and connects to the side bracket. The storage box includes a main frame with a bottom opening and an opening and closing assembly for opening and closing the opening. The opening and closing assembly includes at least two arc-shaped guide holes disposed on the end face of the main frame, an arc-shaped guide strip slidably disposed in the arc-shaped guide holes, and a bottom plate disposed on the arc-shaped guide strip for opening and closing the opening. A pull rope and a return spring are disposed between the tops of the arc-shaped guide strips on the same side, and a side pressure rod for pressing down the pull rope is disposed on the side of the sleeve. This submersible plant seeding device can use drones to lift storage boxes to designated locations. The storage boxes are then lifted by a winding mechanism. During this lifting process, the side pressure rods press down on the pull ropes, causing the top of the arc-shaped guide strips to converge. The bottom plate connected to the guide strips moves, opening the main frame and allowing for seeding. This replaces manual seeding and is more suitable for operation in waters of varying depths, improving both seeding efficiency and safety.

[0007] In the above technical solution, preferably, the drone is provided with a positioning bracket at its bottom, and the bottom of the positioning bracket is provided with a corrugated buffer tube with a through hole in the middle, the bottom of the corrugated buffer tube being connected to the sleeve. This structure can buffer the impact of the storage box on the side pressure rod, avoiding affecting the flight stability of the drone.

[0008] In the above technical solution, preferably, the corrugated buffer tube includes a top seat, a base, and a corrugated tube located between the top seat and the base. The top seat is provided with a plurality of positioning grooves extending laterally from a central through hole, and the base is provided with positioning ribs that align and match the plurality of positioning grooves. This structure allows the positioning ribs to extend into the positioning grooves for positioning after the corrugated tube is compressed, preventing the side pressure rod from swinging or shifting.

[0009] In the above technical solution, preferably, the main frame is divided into several receiving chambers with material dropping gaps. A movable baffle is provided on one side of each receiving chamber to open and close the material dropping gap. A fixed pulley is provided on the top of each receiving chamber, and a limiting bracket is provided on the side of each receiving chamber. A cable is connected to the top of the movable baffle. The cable passes around the fixed pulley, passes through the limiting bracket, and is connected to the lifting seat. A guide rod is provided on the lifting seat, passing through the limiting bracket. A crossbar is provided at the top of the guide rod for being pressed down by the side pressure rod. An adjustment mechanism is provided on the sleeve for adjusting the lateral extension of the side pressure rod. This structure divides the main frame into multiple compartments. By pressing down on the crossbars with side pressure rods, the material drop gaps in the corresponding compartments open when the storage frame rises. For example, when the storage frame is first raised, if the side pressure rod is aligned with only one crossbar, only the crossbar closest to that side pressure rod is pressed down, and only one compartment's drop gap is opened. After this loading, the storage frame is lowered back to its original position, and the lateral extension of the side pressure rod is adjusted by the adjustment mechanism to align it with two crossbars. The next time the storage frame is raised, the two crossbars closest to that side pressure rod are pressed down, opening the drop gaps in both compartments. Since the plants in the previously opened compartment have already been loaded, the plants in the second compartment will be loaded this time. Adjusting the length of the side pressure rod by the adjustment mechanism allows for adjustment of the number of crossbars it aligns with, thus enabling the loading of submerged plants from different compartments into different positions. Different submerged plants can be placed into each compartment according to the loading order, and then categorized for loading.

[0010] In the above technical solution, preferably, the main frame is provided with two first baffles that axially separate the main frame, and a plurality of second baffles that radially separate the main frame are provided between the two first baffles and the side wall of the main frame. The first baffles, any two adjacent second baffles, and the side wall of the main frame are separated to form the receiving chamber. The bottom of the second baffle and the receiving chamber form the material dropping gap. The movable baffle that is slidably disposed in the first baffle to open and close the material dropping gap is raised and lowered.

[0011] In the above technical solution, preferably, the adjusting mechanism includes an adjusting motor fixed on the sleeve and a positioning member with a screw hole. The rotor of the adjusting motor is provided with a non-circular hole that matches the side pressure rod. The side pressure rod passes through the non-circular hole. The outer wall of the side pressure rod is provided with a thread that matches the positioning member. The side pressure rod and the positioning member are threadedly engaged. The lateral extension of the side pressure rod is adjusted by the forward and reverse rotation of the adjusting motor.

[0012] In the above technical solution, preferably, the main frame is provided with an elastic hook for hooking the lifting seat at the pressed-down position, and a tension spring is provided between the lifting seat and the limiting bracket. This structure allows the lifting seat to be positioned by the elastic hook after being pressed down, preventing the already pressed-down lifting seat from resetting and causing repeated pressing during subsequent presses, which would result in excessive force after multiple presses.

[0013] In the above technical solution, preferably, the bottom of the main frame is provided with a guide slope for guiding the plants to fall.

[0014] In the above technical solution, preferably, magnetic blocks are provided on adjacent sides of both of the arc-shaped guide strips. This structure ensures that when the opening of the main frame is blocked and closed by the base plate, the magnetic blocks attract and fix the arc-shaped guide strips, making the base plate positioning more reliable.

[0015] The sowing method of the above-mentioned submerged plant sowing device includes the following steps: S1: Prepare the cultivation soil, plant the submerged plants into the cultivation soil, and place the submerged plants with cultivation soil in each of the receiving chambers; S2: Control the drone to lift the storage box and move it to the delivery location; S3: Adjust the lateral extension of the side pressure rod through the adjustment mechanism, thereby adjusting the number of horizontal bars aligned when the side pressure rod is pressed down; S4: The lifting rope is wound up through the winding mechanism; S5: During the winding process, the side pressure rod at the bottom of the sleeve presses down on the pull rope and the return spring, causing the tops of the two arc-shaped guide bars to converge, opening the bottom plate of the arc-shaped guide bars, and at the same time, the horizontal bar aligned with the side pressure rod is lowered when it is pressed down, raising the corresponding movable baffle; S6: The plant falls through the drop gap between the bottom of the second baffle and the receiving chamber and falls from the opening at the bottom of the main frame of the storage box, completing one delivery.

[0016] Compared with the prior art, this invention has the following advantages: This submerged plant planting device can use a drone to lift the storage box to a designated location. The storage box is then lifted by the winding mechanism. During the lifting process, the side pressure rod presses down on the pull rope, causing the top of the arc-shaped guide strip to converge. The bottom plate connected to the guide strip moves, opening the main frame and allowing for planting. This replaces the manual planting method, making it more suitable for operation in waters of different depths, and improving both planting efficiency and safety. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1 to 5 A submerged plant planting device includes two drones 1 and a storage tank 2. The two drones 1 lift the storage tank 2 from both sides. A sleeve 3 is vertically installed at the bottom of the drone 1, and a winding mechanism 4 is installed at the top of the sleeve 3. The winding mechanism 4 includes a winding bracket, and a winding roller is rotatably installed inside the winding bracket. The roller's shaft is connected to the output shaft of a winding motor fixed on the side of the winding bracket. A side bracket 5 is fixed to the side of the storage tank 2. The lifting rope on the winding mechanism 4 passes through the sleeve 3 and connects to the side bracket 5. The storage tank 2 includes a main frame 6 with a bottom opening and an opening and closing assembly for opening and closing the opening. The opening and closing assembly includes at least two arc-shaped guide holes 7 set on the end face of the main frame 6, an arc-shaped guide strip 8 slidably set in the arc-shaped guide holes 7, and a bottom plate 9 set on the arc-shaped guide strip 8 for opening and closing the opening. A pull rope 10 and a return spring 11 are set between the tops of the arc-shaped guide strips 8 on the same side. A side pressure rod 12 for pressing down the pull rope 10 is set on the side of the sleeve 3. This submersible plant planting device can use a drone 1 to lift the storage box 2 to a designated location. The storage box 2 is then lifted by the winding mechanism 4. During the lifting process, the side pressure rod 12 presses down on the pull rope 10, causing the top of the arc-shaped guide strip 8 to converge. The bottom plate 9 connected to the guide strip moves, opening the main frame 6 and allowing for planting. This replaces the manual planting method and is more suitable for operation in waters of different depths, improving both planting efficiency and safety.

[0023] In this embodiment, a positioning bracket 13 is provided at the bottom of the drone 1, and a corrugated buffer tube 14 with a through hole in the middle is provided at the bottom of the positioning bracket 13. The bottom of the corrugated buffer tube 14 is connected to the sleeve 3. This structure can buffer the impact of the storage box 2 on the side pressure rod 12, so as to avoid affecting the flight stability of the drone 1.

[0024] In this embodiment, the corrugated buffer tube 14 includes a top seat 15, a base 16, and a corrugated tube 17 located between the top seat 15 and the base 16. The top seat 15 is provided with a plurality of positioning grooves 18 extending laterally from a central through hole, and the base 16 is provided with positioning ribs 19 that align and match the plurality of positioning grooves 18. This structure allows the positioning ribs 19 to extend into the positioning grooves 18 for positioning after the corrugated tube 17 is compressed, thus preventing the side pressure rod 12 from swinging and shifting.

[0025] In this embodiment, the main frame 6 is divided into several receiving chambers 20 with material dropping gaps. A movable baffle 21 is provided on one side of the receiving chamber 20 to open and close the material dropping gap. A fixed pulley 22 is provided on the top of each receiving chamber 20. A limit bracket 24 is provided on the side of each receiving chamber 20. A cable 23 is connected to the top of the movable baffle 21. The cable 23 passes around the fixed pulley 22, passes through the limit bracket 24, and is connected to the lifting seat 25. A guide rod 26 is provided on the lifting seat 25, which passes through the limit bracket 24. A crossbar 27 is provided on the top of the guide rod 26 for being pressed down by the side pressure rod 12. An adjustment mechanism 28 is provided on the sleeve 3 for adjusting the lateral extension of the side pressure rod 12. This structure divides the main frame 6 into multiple receiving chambers 20. By pressing down on the crossbars 27 with the side pressure rods 12, the material drop gap of the corresponding receiving chamber 20 can be opened when the storage box rises. For example, if the side pressure rod 12 is aligned with only one crossbar 27 during the first lifting of the storage box, only the crossbar 27 closest to that side pressure rod 12 will be pressed down, and the material drop gap of only one receiving chamber 20 will be opened. After this loading is completed, the storage box is lowered back to its original position, and then the lateral extension of the side pressure rod 12 is adjusted by the adjustment mechanism 28 to align it with two crossbars 27. When the storage box is lifted, the two crossbars 27 closest to the side pressure rod 12 are pressed down, and the material drop gap between the two receiving chambers 20 is opened. Since the plants in the previously opened receiving chamber 20 have already been placed, the plants in the second receiving chamber 20 will be placed this time. The length of the side pressure rod 12 can be adjusted by adjusting the adjustment mechanism 28 to adjust the number of crossbars 27 it is aligned with, so that the submerged plants in different receiving chambers 20 can be placed in different positions. Different submerged plants can be placed into each receiving chamber 20 according to the placement order as needed, and then classified and placed.

[0026] In this embodiment, two first baffles 29 are provided inside the main frame 6 to axially separate the main frame 6. A plurality of second baffles 30 are provided between the two first baffles 29 and the side wall of the main frame 6 to radially separate the main frame 6. The first baffles 29, any two adjacent second baffles 30 and the side wall of the main frame 6 are separated to form a receiving chamber 20. A material dropping gap is formed between the bottom of the second baffles 30 and the receiving chamber 20. A movable baffle 21 is slidably provided inside the first baffles 29 to open and close the material dropping gap.

[0027] In this embodiment, the adjustment mechanism 28 includes an adjustment motor 31 fixed on the sleeve 3 and a positioning member 32 with a screw hole. The rotor of the adjustment motor 31 is provided with a non-circular hole that matches the side pressure rod 12. The side pressure rod 12 passes through the non-circular hole. The outer wall of the side pressure rod 12 is provided with a thread that matches the positioning member 32. The side pressure rod 12 and the positioning member 32 are threadedly engaged. The lateral extension of the side pressure rod 12 is adjusted by adjusting the forward and reverse rotation of the adjustment motor 31.

[0028] In this embodiment, for ease of control, both the winding motor and the regulating motor 31 are controlled via a remote communication module.

[0029] To prevent the already depressed lifting seat 25 from resetting and causing repeated pressure during subsequent presses, resulting in excessive force after multiple presses, this embodiment incorporates the following improvement: an elastic hook 33 is provided within the main frame 6 to hook the lifting seat 25 at its depressed position. A tension spring 34 is provided between the lifting seat 25 and the limiting bracket 24. The top of the elastic hook 33 has an arc-shaped surface. When the lifting seat 25 descends and abuts against the elastic hook 33, the top of the elastic hook 33 experiences a lateral thrust, causing lateral deformation. When the lifting seat 25 passes the top of the elastic hook 33, the elastic hook 33 resets and hooks the lifting seat 25. This structure allows the lifting seat 25 to be positioned by the elastic hook 33 after being depressed. Before the next refilling of submerged plants, the lifting seat 25 can be released by pushing the elastic hook 33 laterally. The lifting seat 25 resets under the tension of the tension spring 34, and the material drop gap is closed by the falling movable baffle 21.

[0030] In this embodiment, in order for the submerged plants to fall smoothly when the material drop gap is opened, the bottom of the main frame 6 is provided with a guide slope 35 for guiding the plants to fall.

[0031] In this embodiment, magnetic blocks 36 are provided on adjacent sides of both arc-shaped guide strips 8. This structure ensures that when the opening of the main frame 6 is blocked and closed by the base plate 9, the magnetic blocks 36 attract and fix the arc-shaped guide strips 8, making the positioning of the base plate 9 more reliable.

[0032] The sowing method of the above-mentioned submerged plant sowing device includes the following steps: S1: Prepare the cultivation soil, plant the submerged plants into the cultivation soil, and place the submerged plants with cultivation soil into each of the receiving chambers 20; S2: Control the drone 1 to lift the storage box 2 and move it to the placement location; S3: Adjust the lateral extension of the side pressure rod 12 through the adjustment mechanism 28, thereby adjusting the number of horizontal bars 27 aligned with when the side pressure rod 12 is pressed down; S4: Operate the winding mechanism 4 to wind up the lifting rope. S5: During the winding process, the side pressure rod 12 at the bottom of the sleeve 3 presses down on the pull rope 10 and the return spring 11, causing the tops of the two arc-shaped guide bars 8 to converge and the bottom plate 9 at the bottom of the arc-shaped guide bars 8 to open. At the same time, when the side pressure rod 12 presses down, the crossbar 27 it is aligned with descends, raising the corresponding movable baffle 21. S5: The plant passes through the material drop gap between the bottom of the second baffle 30 and the receiving chamber 20 and falls from the opening at the bottom of the main frame 6 of the storage box 2, completing one feeding.

[0033] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
