[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is claimed, but merely represents selected embodiments of the present invention.

[0036] See also Figure 1 、 Figure 4 、 Figure 7 and Figure 8 The present invention provides a lotus root harvesting system, comprising a weeding boat and a lotus root harvesting boat. The weeding boat is equipped with a weeding device, a bionic snake-shaped water gun 9, and a soil cleaning brush 11. The weeding device is used to cut and collect lotus leaves, stems, and aquatic plants, while the soil cleaning brush 11 and the bionic snake-shaped water gun 9 are used to scrub and disperse soil, thereby exposing the lotus roots. The soil cleaning brush 11 can move up and down, cooperating with the high-pressure water gun system of the bionic snake-shaped water gun 9 to carefully scrub and disperse soil, ensuring that the lotus roots are exposed intact.

[0037] The lotus root collection boat is equipped with a water filtering device 36, a cleaning device 37, a lotus root straightening device 38, a lotus root conveyor belt 39, and a high-power water pump 40. The high-power water pump 40 pumps water inside the boat hull, collecting the lotus roots through negative pressure on the water surface. The lotus root straightening device 38 adjusts the direction of the lotus roots so that they can enter the lotus root conveyor belt 39. The lotus roots are cleaned by the cleaning device 37 and, after cleaning, are sent to the lotus root collection basket through the lotus root conveyor belt 39. The whale-swallowing collection device utilizes the principle of negative pressure to smoothly suck the lotus roots into the boat cabin, significantly reducing the risk of damaged and broken lotus roots.

[0038] The lotus root straightening device 38 adjusts the lotus roots into a uniform horizontal arrangement to facilitate subsequent cleaning and packaging. The lotus roots are gently pushed and rolled by the soft protrusions of the rotating disk of the lotus root straightening device 38, and are guided to the horizontal direction by the guide groove. The force and speed are precisely controlled to ensure lossless straightening. Afterwards, the lotus roots enter the cleaning device 37. In the conveyor belt, evenly distributed nozzles spray soft water to clean the soil and impurities on the surface of the lotus roots without damaging the epidermis. The lotus roots roll and are washed to achieve deep cleaning. After cleaning, the lotus roots are smooth and sent to a collection box with a partition via a conveyor belt to prevent collisions and maintain their condition. The process is smooth, highly automated, and efficiency is improved.

[0039] Specifically, see Figure 1 The weeding device includes a vertical weeding blade 1, a conveyor belt 2, a rotating bracket 3, a screw 14, and a front weeding blade 15. The vertical weeding blade 1, conveyor belt 2, and front weeding blade 15 are fixedly connected to the weeding frame. The rotating bracket 3 and one end of the screw 14 are respectively hinged to the weeding frame. The rotation of the motor drives the rotation of the screw to adjust the water immersion depth of the weeding frame. There are two vertical weeding blades 1, one on each side of the front end of the weeding frame, and the front weeding blade 15 is located between the two vertical weeding blades 1. During operation, the vertical weeding blades 1 and the front weeding blade 15 swing up and down and left and right to better cut the aquatic weeds.

[0040] Specifically, see Figure 1 The weeding boat also includes a water grass storage box 5, a first lifting rod 7 and a second lifting rod 18. The water grass storage box 5 is used to collect lotus leaves, lotus stems and water grass transmitted by the conveyor belt 2. After the water grass is full, the rear cover 6 of the water grass storage box is lifted by the first lifting rod 7, and the water grass storage box 5 is lifted by the second lifting rod 18, and is dumped through the conveyor belt inside the water grass storage box 5.

[0041] Equipped with automated navigation and sensors, the weeding boats plan their weeding routes based on maps. An automated weeding system cuts and collects impurities from the water surface, while obstacle avoidance adjusts the operation path. Once completed, the boats automatically dock and unload the collected lotus leaves and weeds via a conveyor belt, completing the initial cleaning of the lotus paddy surface and preparing for subsequent lotus root harvesting.

[0042] Specifically, see Figure 2The bionic snake-shaped water gun 9 comprises an elastic cord 23, a connecting module 24, a spring 25, a telescopic barrel 26, and a rigid module 27. The multiple telescopic barrels 26 are connected by the connecting module 24. The elastic cord 23 or spring 25 is attached to the exterior of the telescopic barrel 26, and the rigid module 27 is attached to the exterior of the telescopic barrel 26. The elastic cord 23 and spring 25 extend and retract, allowing the bionic snake-shaped water gun 9 to move freely, changing angles and extending and retracting freely, effectively completing the flushing action. The bionic snake-shaped water gun 9 utilizes a rope-driven flexible spring transmission mechanism to simulate the bending and extension of a snake, enabling 360-degree free flushing, fixed-point positioning, and energy-saving efficiency. The bionic snake-shaped water gun 9 is terminated by a conical nozzle 10. A slightly wider, flat nozzle is added to the front of the cone. This ensures impact while providing a wider spray range, resulting in a more uniform water flow and dispersing the water, reducing concentrated impact on the lotus root. By adjusting the spray angle, the gun avoids spraying directly at the lotus root, instead aiming at an angle to flush the soil. While ensuring the flushing effect, it minimizes damage to the lotus root.

[0043] Specifically, see Figure 1 The weeding boat also includes a solar panel 4 for providing electrical energy to the weeding boat. The solar panel 4 converts solar energy into stored electrical energy, providing clean energy for electronic devices, reducing dependence on fossil fuels and achieving green operations. The electric propulsion system uses solar power to improve energy efficiency, reduce costs, reduce noise and vibration, and enhance operational comfort and boat performance. Figure 1 The brush 22 is fixed to the soil cleaning brush 11. The weeding boat includes a first boat body 16 and a second boat body 20. The second boat body 20 is arranged at the bottom of the first boat body 16. A catamaran 17 is provided on both sides of the first boat body 16. The rear end of the catamaran 17 is provided with a first propeller 8. Wheels are provided on both sides of the bottom of the second boat body 20. The second lifting rod 18 is connected to the catamaran 17 and the aquatic weed storage box 5.

[0044] The weeding and lotus root harvesting boats are constructed from high-strength aluminum alloy, resistant to corrosion and impact, and suitable for brackish water environments. The double-layer hull design features an inner foam or light alloy frame for buoyancy and strength, while the outer layer is abrasion-resistant and scratch-resistant layer, protecting against damage from aquatic weeds and rocks. This ensures lightweight and durability, reduces maintenance costs, and extends the lifespan. Considering the complex terrain of lotus fields, the weeding boats are designed to facilitate transportation and operation. Retractable and retractable wheels allow the boat structure to float on the water, preventing damage to the underwater lotus roots from compaction by the wheels.

[0045] When the weeding boat is working, after the rear wheels 12 and the front wheels 13 are launched into the water, the rear wheels 12 and the front wheels 13 are lifted by the telescopic frame 21, and the hull is driven by the first propeller 8. The conical nozzle 10 is fixedly connected to the bionic snake-shaped water gun 9. After the weeding is completed, the mechanical fish is released through the mechanical fish outlet 19. The mechanical fish scans the lotus root pond, plans the working route of the weeding boat, and flushes water through the conical nozzle 10 of the bionic snake-shaped water gun 9 to collect lotus roots.

[0046] As a preferred embodiment of the present invention, see Figure 6 and Figure 10 The lotus root harvesting system also includes a drone, which includes wings 42 and a main body 44. The main body 44 has claws 43 at its bottom. The drone transports and replaces lotus root collection baskets, thereby improving the harvesting vessel's endurance. The drone transportation system enables rapid and efficient lotus root transportation, reduces manpower, and improves operational safety.

[0047] After cleaning, the lotus roots are placed in a collection bin. When fully loaded, the vessel's lifting device raises them to dock with the drone. The drone's gripper 43 locks onto the collection bin, then takes off vertically to the unloading point. Simultaneously, another drone delivers an empty replacement bin, enabling fast and efficient transportation, reducing manpower and improving speed and safety.

[0048] As a preferred embodiment of the present invention, see Figure 1 The lotus root collecting boat is provided with a vertical lifting device 36, which lifts the lotus root collecting basket.

[0049] As a preferred embodiment of the present invention, see Figure 5 The weeding boat is equipped with a mechanical fish detector that imitates the movement of fish. After the weeding device has finished weeding, the lotus root pond is scanned by the mechanical fish detector, and the position of the lotus roots is identified by sonar and camera, and the data is transmitted back in real time. The weeding boat receives the information, generates a lotus root distribution map, and guides the harvesting operation. The weeding boat locates the lotus roots based on the mechanical fish signal, activates the soil cleaning brush 11 and the bionic snake-shaped water gun 9, brushes and disperses the soil, and gradually exposes the lotus roots. The operator adjusts the strength and direction of the water gun to avoid damaging the lotus roots, and the soft brush cleans carefully to ensure that the lotus roots are intact. After picking, the lotus roots are sucked into the cabin through a whale-swallowing collection device. The automated process ensures the quality and picking efficiency of the lotus roots. Figure 1 The bottom of the second ship body 20 is also provided with a cavity for placing a mechanical fish detector, and a mechanical fish outlet 19 is provided on the cavity. The mechanical fish is automatically recovered after the mission is completed.

[0051] As a preferred embodiment of the present application, refer to Figure 4 、 Figure 8 and Figure 9 , the first hull shell 31 and the second hull shell 33 are fixedly connected. The first hull shell 31 is used to cover the filtered water device 36, the cleaning device 37, the lotus root straightening device 38, and the lotus root conveying belt 39. The track 34 and the retractable frame 35 are mechanically connected. The retractable frame 35 and the second hull shell 33 are mechanically connected to realize the retraction and extension of the track 34. The tail of the second hull shell 33 is provided with a second propeller 32 and a water outlet 41, and the bottom of the second hull shell 33 is provided with a track 34. A high-power water pump 40 is used to pump water in the second hull shell 33 and discharge the pool water out of the second hull shell 33 through the water outlet 41. Figure 3 In the filtered water device main body 28, the corner flange 29, and the right-angled elbow water pipe 30 are mechanically connected. The filtered water device main body 28 is fixedly connected to the second hull shell 33, water is pumped in the lotus root pond, and filtering is performed. After filtering is completed, the water pipe is connected to the cleaning device 37 to clean the lotus roots collected on the lotus root conveying belt 39 for subsequent operation.
