Traditional manual harvesting methods have numerous problems: high labor costs, high labor intensity, and low efficiency, making them unsuitable for modern agricultural production. Currently, lotus root harvesting typically uses high-pressure water jets, which also require personnel to enter the pond. This method suffers from low automation, low harvesting efficiency, and limited functionality. Furthermore, it generally requires manual on-site operation, compromising safety and often facing limitations due to environmental and climatic factors. Summary of the Invention

[0009] Specifically, the power supply mechanism includes a storage battery, which is installed in the vehicle body. A generator that provides charging power to the storage battery is installed in the vehicle body. A pulley is installed at the output end of the generator. The pulley is connected to the output end of a gasoline engine via a transmission belt. The gasoline engine is installed in the vehicle body.

[0010] The beneficial effects of this invention are:

[0011] 1. The machine employs helical hollow wheels. The helical propulsion structure relies on the friction between the threads and the contact surface for operation. Two helical hollow wheels are located on both sides of the bottom of the vehicle body, with the threads of the helical hollow wheels on both sides of the vehicle body facing opposite directions. This counteracts the lateral force during forward movement. The helical hollow wheels are designed to be hollow, thus acting as floats to keep the machine afloat. When the two helical hollow wheels turn in opposite directions, the vehicle body moves forward or backward. When the two helical hollow wheels turn in the same direction, the vehicle body moves left or right. The two helical hollow wheels are driven by two travel drive motors located on both sides of the vehicle body. The controller controls the rotation speed of the travel drive motors to achieve the machine's steering. Driven sprockets are installed on the helical hollow wheels. The power sprocket on the travel drive motor drives the helical hollow wheels to rotate through the first chain, thereby moving the machine.

[0012] 2. The sludge removal mechanism consists of three parts: nozzles, cleaning brushes, and cleaning rollers. The cleaning brushes and nozzles are arranged in multiple rows, alternating between each other. Water is pumped into the cleaning rollers by a water pump. The nozzles spray high-speed water to wash away the sludge, while the cleaning brushes also clean the sludge at the same time. One end of the cleaning roller is equipped with a second sprocket. The second chain meshes with both the second and first sprockets. When the waterproof motor is working, it drives multiple cleaning rollers to rotate through the transmission of the second chain, the second sprocket, and the first sprocket, thus realizing rotary sludge removal.

[0013] 3. The structure formed by multiple cleaning rollers is moved downwards by the second and third electric push rods. When the multiple cleaning rollers come into contact with the sludge surface, the second electric push rod stops running, while the third electric push rod continues to move, causing the structure formed by multiple cleaning rollers to rotate around the cleaning rollers connected to the second electric push rods at both ends. This allows the cleaning rollers near the third electric push rod and the cleaning rollers in the middle position to penetrate into the lower part of the sludge, achieving layered cleaning of the sludge.

[0014] 4. After the silt is washed away, the lotus roots will automatically float on the water surface. Open the two collecting plates located at the front of the vehicle to gather the lotus roots together at the front of the conveyor belt. When the conveyor drive motor is working, it drives the conveyor belt to rotate. The baffles on the conveyor belt transport the lotus roots to the collection box. In addition, there are two first electric push rods rotatably connected to the front of the conveyor belt. In the initial state, the front of the conveyor belt is above the water surface. When it is necessary to collect lotus roots, control the first electric push rods to extend and lower the front of the conveyor belt below the water surface. This makes it easier to collect the lotus roots from the water.

[0015] 5. Planting requires digging holes, placing the lotus root, and covering it with soil. First, remove the collection frame. Adjust the conveyor belt to the appropriate position using the first electric push rod. The distance between the conveyor belt and the bottom of the feeding hopper should be greater than the diameter of one lotus root but less than the diameter of two lotus roots. This allows for the transport of one lotus root. Place the female lotus root to be planted into the feeding hopper. As the conveyor belt rotates, the female lotus root in the feeding hopper is secured in the groove between the baffles on the conveyor belt. The lotus root is then delivered to the planting frame. Control the up and down drive motors to operate, which in turn drive the lifting gear to rotate, causing the lifting gear to drive the rack downwards, thus planting the lotus root. The frame moves downwards and submerges in the silt. Then, the drive motor is activated, which rotates the planting plate via a lever, causing the plate to open outwards and create an opening in the silt. Simultaneously, the lotus root falls into the opening. Then, the up and down drive motors are reversed, causing the planting frame to move upwards. The drive motor is then reversed again, and under the action of the torsion spring, the planting plate re-seals the planting frame. The second soil covering plate, which was folded during the planting process, is opened, and the machine moves forward, covering the lotus root surface with soil. Throughout the planting process, the machine maintains a slow and uniform speed. Attached Figure Description

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Please see Figure 1 , Figure 2 and Figure 3This invention provides a technical solution: a machine for automatically harvesting and planting lotus roots, comprising a vehicle body 1, wherein a cover 6 is hinged to one side of the vehicle body 1, and two spiral hollow wheels 2 are provided on the lower side of the vehicle body 1. The two spiral hollow wheels 2 are symmetrically arranged about a notch 8, and hollow lugs 3 are rotatably connected to both ends of each spiral hollow wheel 2. The lugs 3 are fixed to the bottom of the vehicle body 1, and a driven sprocket located inside the lug 3 is connected and fixed to one end of each spiral hollow wheel 2. Two drive motors 16 are installed inside the vehicle body 1, and the power sprockets installed at the output end of the drive motors 16 are connected to the driven sprockets through a first chain 25. The spiral hollow wheels 2 are used, and the spiral propulsion structure relies on the friction between the threads and the contact surface for operation. The two spiral hollow wheels 2 are located on the vehicle body 1. The spiral hollow wheels 2 on both sides of the bottom and on both sides of the vehicle body 1 have opposite thread directions to counteract the lateral force when moving forward. The spiral hollow wheels 2 are designed to be hollow, thus acting as floats to keep the machine afloat. When the two spiral hollow wheels 2 turn in opposite directions, the vehicle body 1 moves forward or backward. When the two spiral hollow wheels 2 turn in the same direction, the vehicle body 1 moves left or right. The two spiral hollow wheels 2 are driven by two travel drive motors 16, which are located on both sides inside the vehicle body 1. The controller controls the rotation speed of the travel drive motors 16 to achieve the machine's steering. A driven sprocket is installed on the spiral hollow wheel 2. The power sprocket on the travel drive motor 16 drives the spiral hollow wheel 2 to rotate through the first chain 25, thereby moving the machine.

[0037] See Figure 1 , Figure 2 , Figure 9 and Figure 10A notch 8 is provided on one side of the vehicle body 1 adjacent to the cover 6. An inclined conveyor belt 10 for transporting lotus roots is installed within the notch 8. Multiple baffles are evenly spaced on the outer surface of the conveyor belt 10. A detachable collection frame 13 for storing lotus roots is installed on the side of the vehicle body 1 away from the opening of the notch 8. The upper end of the conveyor belt 10 extends to the upper side of the collection frame 13. A drive roller and a reversing roller are provided within the conveyor belt 10. One end of the drive roller is fixedly connected to the output end of a conveyor drive motor 11, which is fixedly connected to the vehicle body 1 via a support rod. The end of the drive roller away from the conveyor drive motor 11 is fixedly connected to the vehicle body 1 via a bracket. Both ends of the reversing roller are rotatably connected to a first electric push rod 4. Two first electric push rods 4 are symmetrically arranged on one side of the notch 8 near its opening. The cylinder end of the first electric push rod 4 is hinged to the vehicle body 1. A collecting plate 5 is provided on both sides of the opening of the notch 8. One end of the collecting plate 5 is hinged to the vehicle body 1, and a first insert is fixedly connected to one side of the collecting plate 5. A first insert is installed inside the first insert. A U-shaped clamp 49 is inserted, with the other end of the U-shaped clamp 49 inserted into a second sleeve. Both sides of the notch 8 are provided with second sleeves that are connected and fixed to the vehicle body 1, so that both ends of the U-shaped clamp 49 are respectively locked into the first sleeves on the two collecting plates 5, thereby sealing the opening of the notch 8 by the two collecting plates 5. The two ends of the U-shaped clamp 49 are respectively locked into the first and second sleeves, thus restricting the position of the collecting plates 5. After the silt is flushed away, the lotus root will automatically float on the water surface, opening the section located at the front of the vehicle body 1. Two collecting plates 5 gather the lotus roots together at the front of the conveyor belt 10. When the conveyor drive motor 11 is working, it drives the conveyor belt 10 to rotate. The baffles on the conveyor belt 10 transport the lotus roots to the collection frame 13. In addition, the front of the conveyor belt 10 is rotatably connected to two first electric push rods 4. In the initial state, the front of the conveyor belt 10 is above the water surface. When it is necessary to collect the lotus roots, the first electric push rods 4 are controlled to extend, lowering the front of the conveyor belt 10 to below the water surface. This makes it easier to collect the lotus roots from the water.

[0038] See Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9The water pump 30 installed inside the vehicle body 1 has a suction pipe 48 installed at its inlet end, with the lower end of the suction pipe 48 extending to the lower side of the vehicle body 1. The water pump 30 is located on the side of the collection frame 13 opposite to the notch 8. Multiple hollow cleaning rollers 20 are arranged in parallel on the lower side of the conveyor belt 10. The multiple cleaning rollers 20 are rotatably installed between the outer shell 21 and the support plate 24. The two ends of the cleaning rollers 20 pass through the outer shell 21 and the support plate 24, respectively. Multiple rows of cleaning brushes 26 are evenly installed on the outer surface of the cleaning rollers 20, and multiple rows of nozzles are evenly installed on the outer surface of the cleaning rollers 20, with the nozzles and cleaning brushes 26 arranged alternately. Rotary joints 27 are installed at both ends of the cleaning rollers 20. Two water supply pipes 29 are installed at the output end of the water pump 30, and the two water supply pipes 29 extend to the outer shell, respectively. On the outer side of the 21 and the outer side of the support plate 24, the ends of the two water supply pipes 29 away from the water pump 30 are each equipped with a water distribution pipe 28. The rotary joints 27 at both ends of the cleaning roller 20 are connected to the two water distribution pipes 28 respectively. The output end of the waterproof motor 34 installed inside the outer casing 21 is equipped with a first sprocket 35. The end of the cleaning roller 20 near the outer casing 21 is fitted with a second sprocket 36 that is connected and fixed to the cleaning roller 20. The second sprocket 36 is located inside the outer casing 21. The second chain 33 inside the outer casing 21 meshes with the first sprocket 35 and the second sprocket 36. The cleaning roller 20 in the middle position among the multiple cleaning rollers 20 is rotatably installed in the U-shaped frame 32. A third electric push rod 31 is connected and fixed at the middle position of the horizontal part of the U-shaped frame 32. 31 is located on the side of the notch 8 near the collection frame 13, and the cylinder end of the third electric push rod 31 is rotatably connected to the vehicle body 1. Among the multiple cleaning rollers 20, the cleaning roller 20 furthest from the third electric push rod 31 has a second electric push rod 7 rotatably connected to both ends. The cylinder end of the second electric push rod 7 is fixedly connected to the vehicle body 1 and is located on the upper side of the vehicle body 1. The sludge removal mechanism consists of three parts: a nozzle, a cleaning brush 26, and a cleaning roller 20. The cleaning brush 26 and the nozzle are arranged in multiple rows, with the cleaning brush 26 and the nozzle arranged alternately. Water is delivered to the cleaning roller 20 by a water pump 30. The nozzle sprays high-speed water to wash away the sludge, and the cleaning brush 26 also cleans the sludge at the same time. A second sprocket 36 and a second chain 33 are provided at one end of the cleaning roller 20. When the waterproof motor 34 is engaged with both the second sprocket 36 and the first sprocket 35, it drives multiple cleaning rollers 20 to rotate via the transmission of the second chain 33, the second sprocket 36, and the first sprocket 35, thus achieving rotary sludge removal. The structure formed by the multiple cleaning rollers 20 is moved downwards by the second electric push rod 7 and the third electric push rod 31. When the multiple cleaning rollers 20 come into contact with the sludge surface, the second electric push rod 7 stops moving, while the third electric push rod 31 continues to move, causing the structure formed by the multiple cleaning rollers 20 to rotate around the cleaning rollers 20 connected to the second electric push rods 7 at both ends. This allows the cleaning rollers 20 near the third electric push rod 31 and those in the middle position to penetrate deeper into the lower part of the sludge, achieving layered sludge removal.The sludge-removing mechanism, formed by multiple cleaning rollers 20, can be adjusted according to different water depths via a second electric push rod 7 and a third electric push rod 31, thus expanding the machine's usability.

[0039] See Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16A planting frame 22 is provided on the side of the bottom of the vehicle body 1 away from the notch 8. The upper end of the planting frame 22 is slidably installed in the positioning frame 23. The positioning frame 23 is fixed to the bottom of the vehicle body 1 and communicates with the internal space of the vehicle body 1. The positioning frame 23 is located directly below the collection frame 13. The bottom of the planting frame 22 is sloping. A planting plate 19 for sealing the bottom of the planting frame 22 is provided at the bottom of the sloping surface. Support shafts 43 are fixedly connected to the two parallel sides of the planting frame 22. Shaft holes are opened on the two parallel sides of the planting plate 19 so that the support shafts 43 are inserted into the shaft holes, completing the rotational connection between the planting plate 19 and the planting frame 22. A torsion spring 45 is snapped on the planting plate 19. The two ends of the torsion spring 45 are respectively sleeved on the two support shafts 43. The free part at the end of the spring 45 contacts the positioning rod 44, which is fixedly connected to the planting plate 19. The output end of the opening drive motor 39 installed on one side of the planting frame 22 is connected to the planting plate 19 through the pull rod 40. The output end of the up and down drive motor 41 installed on one side of the positioning frame 23 is equipped with a lifting gear 42, which meshes with the rack 46. The vertically arranged rack 46 is installed on one side of the planting frame 22. The bottom of the feeding bin 9 located on the upper side of the conveyor belt 10 is inclined. The two parallel sides of the feeding bin 9 are both fixedly connected to the lugs 37. The lower ends of the two vertical rods 38 fixedly connected to the lower surface of the lugs 37 are both fixedly connected to the vehicle body 1. The planting frame 22 is provided with a first soil covering plate on the side away from the notch 8. 17, wherein the upper end of the first soil covering plate 17 is fixedly connected to the vehicle body 1, and the lower end of the first soil covering plate 17 is hinged to the second soil covering plate 18. Planting requires completing the processes of digging holes, placing lotus roots, and covering with soil. First, the collection frame 13 is removed, and the conveyor belt 10 is adjusted to an appropriate position by the first electric push rod 4. The distance between the bottom of the conveyor belt 10 and the feeding bin 9 is required to be greater than the diameter of one lotus root and less than the diameter of two lotus roots, so that one lotus root can be conveyed. The female lotus root to be planted is placed into the feeding bin 9, the conveyor belt 10 rotates, and the female lotus root in the feeding bin 9 is stuck in the groove between the baffles on the conveyor belt 10. Then the lotus root is sent to the planting frame 22. The upper and lower drive motors 41 are controlled to work, and the upper and lower drive motors 41 drive the lifting gear 42 to rotate, so that the lifting gear 42 rotates. The descending gear 42 drives the rack 46 to move downwards, causing the planting frame 22 to move downwards and submerge in the silt. Then, the drive motor 39 is activated, which drives the planting plate 19 to rotate via the pull rod 40, causing the planting plate 19 to open outwards and create an opening in the silt. At the same time, the lotus root falls into the opening. Then, the up and down drive motor 41 is reversed, causing the planting frame 22 to move upwards. The drive motor 39 is then reversed, and under the action of the torsion spring 45, the planting plate 19 re-seals the planting frame 22. The second soil covering plate 18, which is folded during the planting process, is opened, and the machine moves forward, covering the lotus root surface with soil. Throughout the planting process, the machine maintains a slow and uniform speed.

[0040] See Figure 1 and Figure 17 The vehicle body 1 is equipped with a storage battery 14 and a generator 15 that provides charging power to the storage battery 14. The output end of the generator 15 is equipped with a pulley, which is connected to the output end of the gasoline engine 12 installed in the vehicle body 1 via a transmission belt 47. When the gasoline engine 12 is working, it drives the generator 15 to work. The electrical energy generated by the generator 15 is stored in the storage battery 14, providing a continuous source of power for electrical equipment.
