[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a novel front-mounted generator automatic charging hybrid micro-tiller, including a chassis 8, a hydraulic power system and a generator module 2 fixedly connected to one side of the top of the chassis 8, a frame 9 fixedly connected to the top of the chassis 8, a battery box control system 1 fixedly connected to the top of the frame 9, a hydraulic clutch 3 drivenly connected to one side of the hydraulic power system and the generator module 2, and an electric clutch 5 fixedly connected to one side of the top of the chassis 8.

[0022] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the electric clutch 5 and the hydraulic clutch 3 are connected to the power output system 4, and the drive shaft in the power output system 4 is fixedly connected to the walking wheels.

[0023] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, an operating armrest 10 is fixedly connected to one side of the frame 9, and an operating system 7 is integrated on the operating table between the two operating armrests 10.

[0024] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the battery control system 1 consists of a battery pack, a battery monitoring module, and a self-charging module. The fuel power system and generator module 2 includes a fuel engine and a generator. The generator charges the battery pack through the self-charging module, and the battery monitoring module monitors the battery pack's charge, voltage, and current parameters. During operation, the fuel engine is started via the control panel, and the fuel clutch 3 transmits power to the output shaft of the power output system 4 to drive the wheels and enable the rear-mounted tiller to perform tillage. Simultaneously, the input of the electric motor 6 is connected to the output of the fuel engine, allowing the generator to supply power to the battery pack. The start / stop of the fuel engine and electric motor 6 is switched via operation buttons on the control panel, allowing the electric motor 6 to consume electrical energy and provide kinetic energy to drive the wheels. Compared to traditional pure fuel-powered tillers, hybrid tillers reduce fuel consumption and emissions to a certain extent, resulting in less environmental pollution. Hybrid tillers are particularly advantageous in areas with high environmental protection requirements, such as farmland around cities and farmland within ecological protection zones. The electric motor 6 features high torque and fast start-up speed, making starting the mini-tiller easier and more convenient. When the electric motor 6 operates alone, its noise level is significantly lower than that of the internal combustion engine, creating a relatively quiet working environment and reducing noise-related health hazards to operators. In some operating scenarios, the use of the electric motor 6 can reduce reliance on fuel and lower fuel consumption. Furthermore, the automatic charging system can fully utilize the energy generated by the internal combustion engine, further improving energy efficiency and reducing long-term operating costs. The electric motor 6 has a relatively simple structure, lacking complex fuel injection systems, pistons, crankshafts, and other components, resulting in lower maintenance workload and costs. Additionally, the hybrid mini-tiller's battery pack has a long lifespan and requires less frequent replacement, further reducing maintenance costs. The automatic charging system features intelligent charging management, employing a combination of constant current and constant voltage charging based on the battery's charging characteristics to avoid overcharging and undercharging, extending battery life. Moreover, the system can automatically detect and alarm for faults during the charging process, such as short circuits and overheating.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the operating system 7 consists of an operating console and a display screen, a start button, a speed adjustment knob, and a tillage mode switching button on the operating console. The display screen is used to display real-time information on battery level, fuel engine speed, and electric motor power.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, multiple sensors are fixedly connected around the frame 9 and chassis 8. The sensors are used to provide feedback on the load of the tillage blades, the driving speed of the micro-tiller, and the battery status. The sensors feed back electrical signals to the operating system 7 to adjust the output power of the fuel engine, the power generation power of the generator, and the driving power of the electric motor 6.

[0027] The usage and advantages of this utility model: The working process of this new front-mounted generator, automatic charging hybrid micro-tiller, is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, during use, the combustion engine is started via the control panel, and the power is transmitted to the output shaft of the power output system 4 via the hydraulic clutch 3 to drive the walking wheels and enable the rear-mounted tiller to perform tillage operations. While the combustion engine is running, the input end of the electric motor 6 is connected to the output end of the combustion engine, so that the generator supplies power to the battery pack. The start and stop of the combustion engine and the electric motor 6 are switched via the operation buttons on the control panel, so that the electric motor 6 consumes electrical energy and provides kinetic energy to drive the walking wheels.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
