[0020] To address the aforementioned problems, this application provides a distributed-powered remote-controlled soil-cultivating machine. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 The distributed-power remote-controlled ridging machine shown includes a tracked chassis 1, a battery pack 2, rotary tillers 10, and a ridging plow 11. A chassis frame 3 is mounted on the tracked chassis 1, and a range extender 5 and a controller 6 are mounted on the chassis frame 3. Two geared motors 4 are mounted on one side of the tracked chassis 1 as the power source. Two points of a three-point suspension frame 7 are rotatably connected to the other end of the tracked chassis 1. The third point of the three-point suspension frame 7 is adjustablely connected to the chassis frame 3 via an electric push rod 8. The three-point suspension frame 7 is equipped with a rotary tiller blade holder 9, and a rotary tiller blade 10 is connected to the rotary tiller blade holder 9. A rotary tiller motor 12 that drives the rotary tiller blade 10 is installed on the three-point suspension frame 7. A ridging plow 11 is installed at the end of the three-point suspension frame 7. The rotation center line of the rotary tiller blade 10 and the plow head of the ridging plow 11 are located on the same vertical plane. A battery pack box 2 is installed in the center of the tracked vehicle body 1, and a battery pack is installed inside it and connected to the controller 6 to power the equipment. At the same time, a remote communication and remote control module is also installed in the controller 6.

[0022] In this application, a tracked vehicle body 1 is used, with the battery pack and range extender 5 working in tandem. Left and right turning on the spot is achieved through two travel reduction motors 4. The controller 6 contains motor drivers, a remote control receiver module, and signal conversion and communication modules, enabling remote control. A three-point suspension structure connects the rear rotary tiller blades 10 and the ridging plow 11 to the vehicle body, and the raising and lowering of the rotary tiller blades 10 is achieved through an electric push rod 8. An additional power source is added, namely a rotary tiller motor 12 installed above the rotary tiller blades 10 to drive the rotary tiller blades 10 to rotate and achieve rotary tillage. Simultaneously with rotary tillage, the rear ridging plow 11 directionally gathers loose soil towards the sugarcane roots, forming a soil ridge structure conducive to its growth. Thus, the forward-moving vehicle body, controller, rotary tiller blades 10, ridging plow 11, drive motor, and connecting components are all modular and can be replaced individually. Simultaneously, the tracked vehicle body propels the equipment, and two motors drive different tracks in conjunction with the controller, enhancing adaptability to different terrains and soil types. Finally, the sequential arrangement of the rotary tiller blades 10 and ridging plow 11 ensures that the soil is first thoroughly broken up before being precisely ridged, avoiding uneven soil accumulation or poor ridging results, thereby significantly improving operational efficiency and ridging quality.

[0023] In one embodiment, to facilitate the connection of various modules, such as Figure 1 . Figure 6 and Figure 7 As shown, the three-point suspension frame 7 includes a triangular plate 71 and a pivot seat. Connecting beams 72 are fixedly connected to two corners of the triangular plate 71. A first pivot seat 73 is fixedly installed at the end of the connecting beam 72. A mounting plate 75 is perpendicular to the plate surface at the other corner of the triangular plate 71. A second pivot seat 74 is installed at the connection between the mounting plate 75 and the triangular plate 71. Threaded holes are provided on the upper and lower surfaces of the mounting plate 75. A connecting seat 76 is fixedly installed at the end of the mounting plate 75. Simultaneously, a third pivot seat 31 is installed on the chassis frame 3, and a bearing seat 32 is installed on the chassis of the tracked vehicle body 1. One end of the electric push rod 8 is rotatably connected to the third pivot seat 31, and the other end is rotatably connected to the second pivot seat 74. A bearing is connected to the bearing seat 32 and connected to the first pivot seat 73 via a pivot shaft. The rotary tiller blade holder 9 is mounted under the lower surface of the mounting plate 75 by screws. The rotary tiller blade 10 is connected to one end of the rotary tiller blade holder 9 and is connected to the gearbox output shaft of the rotary tiller motor 12 via chain drive.

[0024] In one embodiment, a drive connection structure for a rotary tiller blade 10 is that a rotary tiller blade holder 9 is connected to the lower surface of a mounting plate 75 by screws, and the rotary tiller blade 10 is rotated to one end of the rotary tiller blade holder 9 and connected to the gearbox output shaft of the rotary tiller motor 12 via chain drive.

[0025] In another embodiment, the rotary tiller holder 9 is hollow inside, and a transmission gear is installed therein. The rotary tiller blade 10 is mounted on the rotary tiller holder 9 and is driven by the internal transmission gear. A rotating shaft with a further gear extends from the top of the rotary tiller holder 9 and is connected to the output shaft of the gearbox of the rotary tiller motor 12 via chain drive. In this way, when the rotary tiller blade 10 is tilling, the transmission structure at the blade position is sealed to avoid affecting its normal operation.

[0026] In one embodiment, the rotary tiller 10 employs multiple spoon-shaped blades arranged in a distributed manner, with the blades forming a spiral. The ridging plow 11 has a curved body and is adjustablely connected to the connecting seat 76 via a height adjustment mechanism.

[0027] In this application, the rotary tiller 10 is positioned in front of the ridging plow 11. Its main function is to break up and loosen the soil between the sugarcane rows through high-speed rotation, forming a loose soil structure. The ridging plow 11 follows closely behind, using its special geometry to directionally gather the loose soil towards the sugarcane roots, forming a ridge structure conducive to their growth. This sequential arrangement ensures that the soil is first thoroughly broken up and then precisely ridged, avoiding problems such as uneven soil accumulation or poor ridging effect, thereby significantly improving work efficiency and ridging quality. During operation, the rotary tiller 10 and the ridging plow 11 are connected to the vehicle body via an electric push rod 8 in a three-point suspension structure, and the two are connected by a mounting plate 75. This design allows the rotary tiller 10 to maintain an appropriate working angle during operation, thereby enhancing the soil cutting effect.

[0028] Furthermore, the rotary tiller 10 uses spoon-shaped blades as its main cutting component. Its design is based on the following technical considerations: the curved structure of the spoon-shaped blades generates greater cutting force and soil-turning effect upon contact with the soil. Compared to traditional straight blades, it can cut and toss the soil more efficiently, forming fine soil aggregates that facilitate subsequent hilling. Simultaneously, the geometry of the spoon-shaped blades helps reduce soil adhesion, lowering the blade's resistance in wet or clayey soils, thereby reducing energy consumption and extending blade life. The rotary tiller employs a multi-blade distributed design, with the blades arranged in a spiral pattern to create a larger cutting surface and higher cutting efficiency. The rotary tiller can be equipped with 4-6 blades, the specific number adjustable according to the working width and soil type. Field tests have shown that the spoon-shaped blades can achieve a loosening effect of approximately 50cm in width and 25cm in depth, meeting the agronomical requirements for sugarcane cultivation and hilling.

[0029] The hilling plow 11 is a crucial component responsible for gathering loose soil towards the sugarcane roots. Its design features include: a curved plow body that effectively guides loose soil towards the sugarcane plant roots; and an optimized, arc-shaped conical shovel geometry to reduce soil loss and improve hilling efficiency. A height adjustment device at the top of the plow allows operators to adjust the hilling depth according to soil conditions and the different growth stages of the crop.

[0030] In this application, sugarcane planting plots are typically characterized by narrow row spacing and complex terrain. To adapt to the operational needs between sugarcane rows, the tracked chassis design of this equipment features a narrow track outer edge distance of only 65cm. However, the narrow track design, while meeting the horsepower requirements for both walking and operation, is highly likely to lead to insufficient center of gravity stability. Therefore, a balance between center of gravity stability and horsepower output is achieved through the following methods: In the overall equipment design, the range extender 5 and controller 6 are located near the centerline above the chassis; the battery pack is separately installed near the centerline between the two tracks below the chassis. By lowering the overall center of gravity height, the equipment's anti-tipping ability in narrow row spacing operations is enhanced. Simultaneously, the installation positions of components such as the walking motor with reducer and the working motor with reducer have been calculated based on center of gravity position, torque balance, and power transmission efficiency to ensure a relatively balanced weight distribution between the front and rear, preventing the equipment from tilting forward or backward when operating on slopes.

[0031] To provide sufficient driving force despite its narrow track design, this equipment employs a distributed power system to ensure optimal performance in complex operating environments. Specifically, the travel motor paired with a reducer ensures good traction on various terrains, meeting the need for flexible movement in the narrow rows of sugarcane fields. On the other hand, the work motor paired with a reducer provides powerful cutting and turning capabilities to meet the operational needs under different soil conditions, and its high power output allows the rotary tiller blades 10 to operate continuously under high loads. Field verification has shown that this equipment not only meets the requirements for narrow passage in sugarcane fields but also achieves operating horsepower comparable to traditional tractor-driven tillers, while maintaining a stable center of gravity and significantly reducing the risk of rollover.

[0032] To enhance the equipment's adaptability and stability in complex terrain conditions, the third and fourth sets of driven wheels are designed as floating wheels in the tracked chassis. These floating wheels are connected to the tracked chassis via an elastic device, enabling them to float within a certain range in the vertical direction, thus giving the tracked system greater flexibility. When the equipment encounters uneven terrain such as stones or ditches in sugarcane fields, the floating wheels can adaptively adjust their position according to the ground undulations, maintaining the effective contact area between the tracks and the ground and avoiding the risk of equipment rollover due to concentrated local forces.

[0033] During operation, the adaptive adjustment of the floating wheels maintains good contact between the tracks and the ground, maximizing traction and operational efficiency. Furthermore, the floating wheel design effectively absorbs the impact of terrain changes, reducing the influence of overall machine vibration on critical components such as the controller and battery pack, thereby improving the equipment's operational stability and lifespan.

[0034] This application employs a hybrid power system that combines battery packs and range extenders for power supply, ensuring continuous operation while reducing energy consumption and emissions, thus improving the equipment's environmental performance. Two independent drive motors with reducers drive the tracked chassis, enabling differential speed control of the left and right tracks. This allows for on-the-spot turning in confined spaces, significantly enhancing the equipment's maneuverability. A remote control system allows operators to precisely control the equipment from a safe distance, reducing labor intensity and improving operational safety. A three-point suspended cutter mounting structure, combined with an electric push rod lifting system, allows for adjustment of the working depth according to different crops and soil conditions, making it suitable for various agronomic requirements.

[0035] The workflow for this application is as follows: Workflow: 1. The range extender starts and establishes a stable power output. The relevant controllers in the electrical control cabinet within the controller await remote control commands, and the battery pack enters standby mode. The control system activates all mechanisms, ensuring that key components such as the travel motor with reducer, the work motor with reducer, and the electric push rod are in normal working condition.

[0036] 2. Movement commands are sent via remote control. Upon receiving the signal, the relevant modules within the controller drive the walking motor and reducer, propelling the tracked chassis to the work area. The working depth and tilt angle of the tillage plow and rotary tiller are adjusted using an electric push rod to adapt to different soil conditions.

[0037] 3. The working motor, equipped with a reducer, receives control signals from the controller and distributes power to the rotary tillage blades according to a preset transmission ratio via the working gearbox. This distributed power system ensures that each actuator receives independent and stable power input, preventing machine downtime due to a single power source failure.

[0038] 4. The rotary tiller blades rotate at high speed driven by the working motor and reducer. The blades contact the soil and produce the following effects: Loosen the soil between the sugarcane rows with a width of about 50cm and a depth of about 25cm to meet the requirements for sugarcane hilling. Cultivating and cutting off the roots of weeds destroys their growing environment; Optimize soil aggregate structure to improve soil permeability and water retention.

[0039] 5. The ridging plow follows closely behind the rotary tiller blades, using its unique geometry to gather loose soil towards the roots of the sugarcane plants. Through real-time adjustments with an electric pusher, it creates a ridge structure conducive to sugarcane growth.

[0040] 6. The implement continues to advance along the sugarcane ridges, with inter-row cultivation and hilling operations carried out simultaneously. The motor driver inside the controller has a function to monitor motor indicators. When an abnormality is detected, the system automatically stops working to ensure work quality and equipment safety.
