Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a new type of micro-tiller structure with dual-use (oil and electricity) and unlimited range. Background Technology

[0002] Mini tillers are small agricultural machines popular among farmers for their portability, flexibility, versatility, and affordability. Their compact size and easy mobility make them ideal for small plots of land, making them frequently used for land preparation in hilly areas, greenhouses, vegetable gardens, and orchards. The main functions of a mini tiller include tilling, ridging, ditching, and weeding. Their small size makes them suitable for dry land, paddy fields, and orchards in plains, mountains, and hills. The tilling function allows for free movement in the field, making them easy to use and store. The ridging height can be adjusted using the mini tiller itself. Ditching is achieved by using appropriate blades; different models of mini tillers have different ditch depths. Weeding is achieved by changing the blades, making it very convenient and quick.

[0003] Existing mini-tillers are mostly fuel-powered and generally bulky. They are typically powered by either gasoline or diesel. These mini-tillers are complex to operate and pose certain dangers, consume a lot of energy, pollute the environment, are inconvenient to start, and are not convenient for the elderly and women to use. After the busy farming season, they are often left idle at home, which can easily lead to rust. Furthermore, the fuel in the tank can easily evaporate and be emptied. Therefore, there is a need for a new type of mini-tiller that can run on both gasoline and electric power with unlimited range to meet people's needs. Utility Model Content

[0011] Preferably, a control unit is mounted on the side of the battery box, a transmission gearbox is installed between the engine and the permanent magnet brushless motor, and multiple lead-acid batteries are installed inside the battery box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting up a gasoline engine and a permanent magnet brushless current machine, when the main body of the device is used, the gasoline engine or the permanent magnet brushless current machine drives the main body of the device to move as a whole. The driving wheels are rotated by the power of the gasoline engine or the permanent magnet brushless current machine. When the gasoline engine is used, it can charge multiple lead-acid batteries in the battery box. When more power is needed, it can switch to the fuel engine to work, so that the staff can select the oil and electricity mode according to the site environment, so that the main body of the device can maintain good working efficiency for a long time.

[0013] (2) By setting up a blade changing crowbar and a tillage blade, the blades to be plowed are installed at the front end of the main body of the device through the blade changing crowbar. When the main body of the device is started to till the land, it helps the workers to cut away the weeds that are blocking the operation. While the main body of the device moves, the tillage blade at the rear end tills the cut ground. When it is necessary to plant crops, it is more convenient to fill the soil and cover it, thus improving the applicability of the main body of the device. Attached Figure Description

[0019] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a novel micro-tiller structure with dual-use (oil and electricity) and unlimited range, including a main body 1, a bracket 2 installed at one end of the main body 1, a battery box 3 installed on the top of the bracket 2, a connecting seat 4 installed on the side of the bracket 2, a gasoline engine 5 installed at one end of the battery box 3, a fuel tank 6 installed at one end of the gasoline engine 5, an engine 7 installed at the bottom of the gasoline engine 5, a permanent magnet brushless motor 8 installed at one end of the engine 7, a waterproof cover 9 installed on the side of the permanent magnet brushless motor 8, and a connecting seat 4 at one end... An operating handle 10 is installed, and a control mounting plate 11 is installed on the side of the operating handle 10. A gear shift lever 12 is installed at one end of the control mounting plate 11. A handle 13 is installed at one end of the operating handle 10, and a clutch grip 14 is installed at the other end of the operating handle 10. A light 20 is installed at one end of the battery box 3, and a horn 21 is installed at the other end of the battery box 3. A bent locking rod 25 is installed on the side of the connecting seat 4, and the bent locking rod 25 is adapted to the operating handle 10. A control unit 22 is installed on the side of the battery box 3. A transmission gearbox 23 is installed between the motor 7 and the permanent magnet brushless current generator 8. Multiple lead-acid batteries 24 are installed in the battery box 3. When using the main body 1, fuel is added to the fuel tank 6, and the gasoline engine 5 powers the main body 1, controlling the kinetic energy of the motor body 22 and rotating the wheels 17. When electric power is required, the battery box 3 can be switched to power supply mode, allowing the permanent magnet brushless current generator 8 to drive the wheels 17. The operator holds both ends of the operating handle 10 and uses the handle 13 and clutch grip 14 to operate the motor. By controlling the main body 1 of the device and using the engine 7 and the permanent magnet brushless motor 8 for hybrid operation, the operating range and working efficiency of the main body 1 can be improved. While using the engine 7 for power, the current generated by the permanent magnet brushless motor 8 can be recovered to charge the lead-acid battery 24 and supplement the operating range of the main body 1. The transmission gearbox 23 can adjust the speed of the main body 1. Through hybrid power supply, the main body 1 can work under high load for a long time, improving the working efficiency during agricultural work.

[0020] Example 2: Figure 1 and 4As shown, a front support rod 15 is installed at one end of the bracket 2, a blade changing pry bar 16 is installed at the bottom of the bracket 2, two traveling wheels 17 are installed at one end of the bracket 2, a mudguard 18 is installed at one end of the traveling wheels 17, and a tillage blade 19 is installed at one end of the main body 1 of the device. The cutting blade is installed at one end of the front support rod 15 through the blade changing pry bar 16. When the traveling wheels 17 rotate, the blade cuts the weeds at the front end to prevent them from blocking or tangling the main body 1 of the device. The tillage blade 19 at the rear end of the main body 1 is used to rotary till and turn the soil, helping the workers to plant crops better. When the traveling wheels 17 rotate, the mudguards 18 at both ends prevent soil from splashing, giving the workers a good operating space. The remaining features are the same as in embodiment 1.

[0021] The working principle is as follows: When using the main body 1, fuel is added to the fuel tank 6, and the gasoline engine 5 powers the main body 1. The control unit 22 controls the kinetic energy and drives the walking wheels 17 to rotate. When electric power is required, the battery box 3 can be used to switch to the power supply mode, so that the permanent magnet brushless motor 8 drives the walking wheels 17. The operator holds both ends of the operating handle 10 and controls the main body 1 through the handle 13 and the clutch lever 14. The cutting blade is installed at one end of the front support rod 15 through the blade changing pry bar 16. When the walking wheels 17 rotate, the blade cuts the weeds at the front end, preventing them from blocking or tangling the main body 1. The tilling blade 1 at the rear end of the main body 1 cuts the weeds. The device performs rotary tillage on the fields, helping workers to better cultivate crops. The hybrid operation of the engine 7 and permanent magnet brushless motor 8 improves the endurance and work efficiency of the main unit 1. While the engine 7 provides power, the current generated by the permanent magnet brushless motor 8 can be recovered to charge the lead-acid battery 24, supplementing the endurance of the main unit 1. The transmission gearbox 23 allows for speed regulation of the main unit 1. When the wheels 17 rotate, the mudguards 18 at both ends prevent mud from splashing, providing workers with good operating space. The hybrid power supply allows the main unit 1 to work under high load for extended periods, improving work efficiency during agricultural operations.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
