Technical Field

[0001] The invention belongs to the technical field of submerged plant planting, and in particular relates to a submerged plant planting device and a planting method thereof. Background Art

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

[0003] Therefore, developing a device that can efficiently, accurately and safely plant submerged plants in designated waters is of great significance to promoting the progress of water ecological restoration work.

[0004] The existing method of planting submerged plants generally involves pre-planting the submerged plants in a container with culture soil, and then placing the container at a designated location. However, this planting method still requires manual labor, and workers need to drive a boat to the designated location to plant the plants one by one. Especially for locations with shallow water levels, it is impossible to drive a boat, and workers need to plant the plants in the water. The planting efficiency is low and there is a certain degree of danger. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a submerged plant planting device and a planting method thereof. The submerged plant planting device can rely on a drone to fly to a designated location for rapid planting, greatly improving planting efficiency and safety.

[0006] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a submerged plant planting device, comprising at least two drones and a storage box, a sleeve is vertically arranged at the bottom of the drone, a winding mechanism is arranged on the top of the sleeve, a side bracket is fixed to the side of the storage box, the lifting rope on the winding mechanism passes through the sleeve and is connected to the side bracket, the storage box comprises a main frame with a bottom opening and an opening and closing assembly for opening and closing the opening, the opening and closing assembly comprises at least two arc-shaped guide holes arranged on the end face of the main frame, an arc-shaped guide bar slidably arranged in the arc-shaped guide hole, and a bottom plate for opening and closing the opening arranged on the arc-shaped guide bar, a pull rope and a reset spring are arranged between the tops of the arc-shaped guide bars on the same side, and a side pressure rod for pressing down the pull rope is provided on the side of the sleeve. This submerged plant planting device can use a drone to lift the storage box to a designated location, and the storage box can be moved upward as a whole by reeling in the reeling mechanism. During the upward movement, the side pressure rod presses down the pull rope, causing the top of the arc-shaped guide bar to gather, and the bottom plate connected to the guide bar moves so that the opening of the main frame is opened, thereby allowing the plant to be planted. This replaces the manual placement method, is more conducive to operations in waters of different depths, and improves the placement efficiency and safety.

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

[0009] In the above technical solution, preferably, a number of accommodating chambers with blanking gaps are divided in the main frame, a movable baffle is provided on one side of the accommodating chamber to be lifted and lowered to open and close the blanking gap, a fixed pulley is provided on the top of each accommodating chamber, and a limiting bracket is provided on the side of each accommodating chamber, a cable is connected to the top of the movable baffle, the cable passes around the fixed pulley and passes through the limiting bracket and is connected to the lifting seat, a guide rod passing through the limiting bracket is provided on the lifting seat, a cross bar for being pressed down by the side pressure rod is provided on the top of the guide rod, and an adjustment mechanism for adjusting the lateral extension amount of the side pressure rod is provided on the sleeve. By adopting this structure, the main frame is divided into multiple storage chambers. The side pressure rods press the cross bars, and the blanking gaps of the corresponding storage chambers can be opened when the storage frame rises. For example, when the storage frame is lifted for the first time, the side pressure rods are only aimed at one cross bar, so only the cross bar closest to the side pressure rod is pressed down, and the blanking gap of only one storage chamber is opened. After completing this delivery, the storage frame is lowered and reset, and then the lateral extension of the side pressure rods is adjusted by the adjustment mechanism to align them with the two cross bars. When the storage frame is lifted next time, the two cross bars closest to the side pressure rods are pressed down, and the blanking gaps of the two storage chambers are opened. The plants in the storage chamber opened last time have already been delivered, so the plants in the second storage chamber will be delivered this time. By adjusting the length of the side pressure rods by the adjustment mechanism, the number of cross bars it is aligned with can be adjusted, so that the submerged plants in different storage chambers can be delivered to different positions, and different submerged plants can be placed in each storage chamber according to the delivery order as needed, and then classified and delivered.

[0010] In the above technical solution, preferably, two first baffles are provided in the main frame body to axially separate the main frame body, and a plurality of second baffles are provided between the two first baffles and the side walls of the main frame body to radially separate the main frame body. The first baffle and any two adjacent second baffles and the side walls of the main frame body are separated to form the accommodating chamber, and the blanking gap is formed between the bottom of the second baffle and the accommodating chamber, and the movable baffle that is lifted and lowered to open and close the blanking gap is slidably provided in the first baffle.

[0012] In the above technical solution, preferably, an elastic hook is provided within the main frame for hooking the lift seat at the depressed position, and a tension spring is provided between the lift seat and the limit bracket. This structure allows the elastic hook to hook the lift seat and position it after it is depressed, preventing the lift seat from resetting after it has been depressed, which would cause repeated depressions during subsequent depressions and result in excessive force required after multiple depressions.

[0013] In the above technical solution, preferably, a guiding slope for guiding the falling of plants is provided at the bottom of the main frame.

[0014] In the above technical solution, preferably, magnets are provided on adjacent sides of the two arc-shaped guide strips. With this structure, when the opening of the main frame is blocked and closed by the bottom plate, the magnets attract and fix the arc-shaped guide strips, making the bottom plate positioning more reliable.

[0015] The planting method of the above-mentioned submerged plant planting device includes the following steps: S1: preparing cultivation soil, implanting the submerged plants into the cultivation soil, and placing the submerged plants with the cultivation soil in each containing chamber respectively; S2: controlling the drone to lift the storage box and move it to the delivery location; S3: adjusting the lateral extension of the side pressure rod through the adjustment mechanism, thereby adjusting the number of cross bars aligned with the side pressure rod when it is pressed down, S4: reeling the lifting rope through the reeling mechanism; S5: during the reeling process, the side pressure rod at the bottom end of the sleeve presses the pull rope and the return spring downward, so that the top ends of the two arc-shaped guide bars are gathered, and the bottom plate of the bottom of the arc-shaped guide bar is opened. At the same time, when the side pressure rod is pressed down, the cross bar it is aligned with is lowered, and the corresponding movable baffle is lifted; S5: the plant passes through the blanking gap between the bottom of the second baffle and the containing 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, the present invention has the following beneficial effects: this submerged plant planting device can lift the storage box to the designated position by a drone, and the storage box can be moved upward as a whole by the winding of the winding mechanism. During the upward movement, the side pressure rod presses the pull rope downward, so that the top of the arc-shaped guide bar gathers, and the bottom plate connected to the guide bar moves so that the opening of the main frame is opened, so that the planting is carried out, replacing the manual planting method, which is more conducive to operations in waters of different water depths, and the planting efficiency and safety are improved.

The lifting mechanism 4 is a kind of lifting mechanism that lifts and lowers the lifting device 1 and lifting frame 2. The lifting mechanism 4 is a kind of lifting mechanism that lifts and lowers the lifting device 1 and lifting frame 2. The lifting mechanism 4 is a kind of lifting mechanism that lifts and lowers the lifting device 1 and lifting frame 2. The lifting mechanism 4 is a kind of lifting mechanism that lifts and lowers the lifting device 1 and lifting frame 2. The lifting mechanism 4 is a kind of lifting mechanism that lifts and lowers the lifting device 1 and lifting frame 2. This submerged plant planting device can lift the storage box 2 to the designated position through the drone 1, and the storage box 2 is moved upward as a whole by the winding mechanism 4. During the upward movement, the side pressure rod 12 presses the pull rope 10 downward, so that the top of the arc-shaped guide bar 8 gathers, and the bottom plate 9 connected to the guide bar moves so that the opening of the main frame 6 is opened, so that the planting is carried out, replacing the manual planting method, which is more conducive to operations in waters of different depths, and the planting efficiency and safety are improved.

[0023] In this embodiment, the drone 1 is provided with a positioning bracket 13 at its bottom. 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 cushion the impact of the storage box 2 on the side pressure rod 12, thereby preventing the drone 1 from affecting its flight stability.

[0024] In this embodiment, the bellows buffer tube 14 includes a top seat 15, a base 16, and a bellows 17 positioned between the top and base seats 15 and 16. The top seat 15 is provided with a plurality of positioning slots 18 extending laterally from a central through-hole, and the base 16 is provided with positioning ribs 19 that align with the positioning slots 18. This structure allows the positioning ribs 19 to extend into the positioning slots 18 after the bellows 17 is compressed, preventing the side pressure rod 12 from swinging or deflecting.

[0025] In this embodiment, a number of receiving chambers 20 with blanking gaps are formed in the main frame 6. A movable baffle 21 is provided on one side of the receiving chamber 20 to be raised and lowered to open and close the blanking gap. A fixed pulley 22 is provided on the top of each receiving chamber 20, and a limiting 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 and passes through the limiting bracket 24 and is connected to the lifting seat 25. The lifting seat 25 is provided with a guide rod 26 that passes through the limiting bracket 24. A cross bar 27 for being pressed down by the side pressure rod 12 is provided on the top of the guide rod 26. An adjustment mechanism 28 for adjusting the lateral extension amount of the side pressure rod 12 is provided on the sleeve 3. With this structure, the main frame 6 is divided into a plurality of accommodating chambers 20. By pressing the cross bars 27 with the side pressure rods 12, the blanking gap of the corresponding accommodating chamber 20 can be opened when the material storage frame rises. For example, when the material storage frame is lifted for the first time, the side pressure rods 12 are only aligned with one cross bar 27, so that only the cross bar 27 closest to the side pressure rod 12 is pressed down, and the blanking gap of only one accommodating chamber 20 is opened. After completing this feeding, the material storage frame is lowered and reset, and then the lateral extension of the side pressure rods 12 is adjusted by the adjustment mechanism 28 to align with the two cross bars 27, and then the material storage frame is lowered. When the storage frame is lifted once, the two cross bars 27 closest to the side pressure rod 12 are pressed down, and the blanking gap between the two receiving chambers 20 is opened. The plants in the previously opened receiving chamber 20 have been put in, so the plants in the second receiving chamber 20 will be put in this time. By adjusting the length of the side pressure rod 12 through the adjustment mechanism 28, the number of cross bars 27 it is aligned with can be adjusted, so that the submerged plants in different receiving chambers 20 can be put into different positions, and different submerged plants can be placed in each receiving chamber 20 according to the order of placement as needed, and then classified and placed.

The first baffle 29 and any two adjacent second baffles 30 and the side walls of the main frame 6 are separated to form a receiving chamber 20, and a blanking gap is formed between the bottom of the second baffle 30 and the receiving chamber 20. A movable baffle 21 is slidably provided in the first baffle 29 to lift and lower to open and close the blanking 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 matching the side pressure rod 12. The side pressure rod 12 is inserted into the non-circular hole. The outer wall of the side pressure rod 12 is provided with a thread matching the positioning member 32. The side pressure rod 12 is threadedly matched with the positioning member 32. The lateral extension of the side pressure rod 12 is adjusted by rotating the adjustment motor 31 forward and reverse.

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

[0029] To prevent the lifting seat 25 from resetting after it has been pressed down, which would cause repeated pressing during subsequent pressing, resulting in excessive force required after multiple pressing operations, this embodiment also incorporates the following improvements: an elastic hook 33 is provided within the main frame 6 to hook the lifting seat 25 in 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 arcuate surface. When the lifting seat 25 descends and abuts against the elastic hook 33, the top of the elastic hook 33 is subjected to a lateral thrust, causing the elastic hook 33 to deform laterally. When the lifting seat 25 passes over the top of the elastic hook 33, the elastic hook 33 resets and hooks the lifting seat 25. With this structure, the elastic hook 33 can hook the lifting seat 25 after the lifting seat 25 is pressed down, keeping it in place. Before reloading the 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 blanking gap is closed by the falling movable baffle 21.

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

[0031] In this embodiment, magnets 36 are provided on adjacent sides of the two arc-shaped guide strips 8. With this structure, when the opening of the main frame 6 is blocked and closed by the bottom plate 9, the magnets 36 attract and fix the arc-shaped guide strips 8, making the bottom plate 9 more reliably positioned.

[0032] The planting method of the above-mentioned submerged plant planting device includes the following steps: S1: preparing cultivation soil, planting submerged plants in the cultivation soil, and placing the submerged plants with the cultivation soil in each receiving chamber 20; S2: controlling the drone 1 to lift the storage box 2 and move it to the placement location; S3: adjusting the lateral extension amount of the side pressure rod 12 through the adjustment mechanism 28, thereby adjusting the number of cross bars 27 that the side pressure rod 12 is aligned with when it is pressed down; S4: reeling in the lifting rope through the winding mechanism 4. Roll; S5: During the winding process, the side pressure rod 12 at the bottom end of the sleeve 3 presses the pull rope 10 and the return spring 11 downward, so that the top ends of the two arc-shaped guide bars 8 are gathered, and the bottom plate 9 at the bottom of the arc-shaped guide bar 8 is opened. At the same time, when the side pressure rod 12 is pressed down, the cross bar 27 to which it is aligned drops, and the corresponding movable baffle 21 is lifted; S5: The plant passes through the blanking gap between the bottom of the second baffle 30 and the accommodating chamber 20, and falls from the opening at the bottom of the main frame 6 of the storage box 2, completing one delivery.

[0033] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
