[0002] A mini tiller is a small agricultural machine mainly used for soil cultivation in small plots of farmland, orchards, and vegetable gardens. It has a compact structure, is relatively easy to operate, and effectively reduces manual labor intensity while improving cultivation efficiency. Typically, a mini tiller consists of a power system (such as a small engine or motor), a transmission device, operating control components, and actuators (tiller blades, wheels, etc.). The power system provides the necessary power for operation, which is distributed to the wheels via the transmission device to move the machine, while simultaneously driving the tiller blades to rotate at high speed to complete the soil turning operation. Due to its small size and ease of operation, the mini tiller plays an important role in small-plot farming scenarios, becoming a valuable tool for many farmers and small-scale growers. However, most existing mini tillers have a one-piece structure, which is relatively fixed and inconvenient to store; furthermore, when it is necessary to move the work site, such as from one's own farmland to a distant orchard, the transportation process is inconvenient, increasing usage costs and time costs. This contradicts users' demand for convenient and efficient agricultural tools, limiting the flexible application of mini tillers in different scenarios. Summary of the Invention

Specific Implementation Example 1:

[0040] Please refer to Figures 1 to 4 As shown, this embodiment provides a portable micro-tiller, including:

[0041] The machine head 1 is equipped with a drive motor 11, a planetary reducer 12, and a helical gear coupling 13 that are sequentially connected in transmission. The helical gear coupling 13 includes a vertical transmission rod 131 and a horizontal transmission shaft 132 that are connected in transmission to the planetary reducer 12. A gear 133 coupled to the vertical transmission rod 131 is fixedly installed on the horizontal transmission shaft 132. Rotary tillage blades 134 are fixedly installed at both ends of the horizontal transmission shaft 132.

[0042] Connecting rod 2, the connecting rod 2 includes a first connecting rod 21 and a second connecting rod 22, one end of the first connecting rod 21 is detachably installed to the machine head 1, and the other end is detachably connected to one end of the second connecting rod 22;

[0043] Control handle 3, which is detachably mounted on the other end of the second connecting rod 22.

[0044] In this embodiment, the body 1 and the second connecting rod 21 are detachable, the first connecting rod 21 and the second connecting rod 22 are detachable, and the second connecting rod 22 and the control handle 3 are detachable. Thus, when the portable tiller is not needed or the work location of the portable tiller needs to be moved, at least the second connecting rod 22 and the first connecting rod 21 of the portable tiller can be separated, reducing the length of the portable tiller and making it easier to store or transport.

[0045] For preferred options, please refer to [the provided text]. Figure 2 As shown, in this embodiment, the diameters of the first connecting rod 21 and the second connecting rod 22 are different, and the first connecting rod 21 can slide within the second connecting rod 22; the connecting rod 2 also includes a locking member 24, which is disposed at the junction of the first connecting member 21 and the second connecting member 22 to achieve fixation between the two.

[0046] In this embodiment, the outer diameter of the first connecting rod 21 is slightly smaller than the inner diameter of the second connecting member 22, allowing the first connecting rod 21 to extend into and slide inside the second connecting rod 22, thus achieving the telescopic performance of the connecting rod 2. This makes it suitable for different scenarios and facilitates user operation. Furthermore, to prevent the first connecting rod 21 from moving into the second connecting rod 22 under force during the operation of the portable micro-tiller, this embodiment also provides a locking member 24. The locking member 24 is installed at the junction of the first connecting rod 21 and the second connecting rod 22, specifically occupying half of each. After the locking member 24 is locked, the first connecting rod 21 and the second connecting rod 22 can no longer slide relative to each other.

[0047] For preferred options, please refer to [the provided text]. Figure 1 and Figure 2As shown, in this embodiment, the control handle 3 is equipped with a locking button 31 and a switch 32 for starting the drive motor 11 inside the starter head 1. Furthermore, the control handle 3 is also equipped with a power-on base 33, on which a battery pack 4 is detachably mounted.

[0048] In this embodiment, a dual switch, a locking button 31 and a switch 32, is provided to prevent accidental activation of the rotary tiller 134. After the battery pack 4 is installed on the power base 33, it can serve as the working power source for the portable micro-tiller, facilitating its outdoor operation. When the work is finished, the battery pack 4 can be removed for charging.

[0049] For preferred options, please refer to [the provided text]. Figures 1 to 4 As shown, in this embodiment, the portable micro-tiller also includes an auxiliary handle 5, which includes a lifting ring 51 and an adjustable buckle 52 disposed at the closing part of the lifting ring 51. The auxiliary handle 5 is locked onto the second connecting rod 22 by the adjustable buckle 52. Further, the openings of the lifting ring 51 and the adjustable buckle 52 face the same direction, and the adjustable buckle 52 is disposed inside the lifting ring 51. The auxiliary handle 5 is provided with a knob screw 53 at the opening of the lifting ring 51 and the adjustable buckle 52. The knob screw 53 passes through the lifting ring 51 and the adjustable buckle 52 to fix the second connecting rod 22 inside the adjustable buckle 52.

[0050] In this embodiment, an auxiliary handle 5 is provided to facilitate better user control of the portable tiller. When using the portable tiller, the user can hold the control handle 3 with one hand and the auxiliary handle 5 with the other, making two-handed control more effortless and easier to operate than one-handed control. Furthermore, the adjustable buckle 52 can slide on the second connecting rod 22. When the user determines the appropriate height, rotating the knob screw 53 can lock the adjustable buckle 52 and the lifting ring 51 onto the second connecting rod 22. The adjustable buckle 52 and knob screw 53 allow adjustment of the specific position of the lifting ring 51 on the second connecting rod 22, enabling the portable tiller to adapt to different working environments and to accommodate different operator body shapes.

[0051] For preferred options, please refer to [the provided text]. Figure 2 and Figure 3 As shown, in this embodiment, the machine head 1 includes a first housing 14 and a second housing 15, which are fastened together and form an internal mounting cavity for fixing and installing the drive motor 11, the planetary reducer 12 and the helical gear mating part 13; the two ends of the horizontal transmission shaft 132 extend out of the first housing 14 and the second housing 15 respectively and are fixedly installed with the rotary tiller blade 134.

[0052] In this embodiment, the drive motor 11, planetary reducer 12, and helical gear fitting 13 are disposed in the receiving cavity formed by the fastening of the first housing 14 and the second housing 15. Thus, during the operation of the portable micro-tiller, foreign objects can be prevented from entering and affecting the transmission connection between the three components, and the normal operation of the portable micro-tiller can be ensured. Specific Implementation Example 2:

[0054] Please refer to Figure 5 and Figure 6 As shown, the main difference between this embodiment and the first embodiment is that the connecting rod 2 in this embodiment is provided with an elastic rope 23. For other structures, please refer to the first embodiment, which will not be described again here.

[0055] like Figure 5 and Figure 6 As shown, in this embodiment, the connecting rod 2 further includes an elastic rope 23, which is disposed inside the first connecting rod 21 and the second connecting rod 22 so that the first connecting rod 21 and the second connecting rod 22 can be folded relative to each other.

[0056] In this embodiment, an elastic rope 23 is provided inside the first connecting rod 21 and the second connecting rod 22. The elasticity of the elastic rope 23 can be used to separate, fasten, and fold the first connecting rod 21 and the second connecting rod 22. This makes it easier to store the portable micro-tiller and improves the connection strength between the first connecting rod 21 and the second connecting rod 22. Specific Implementation Example 3:

[0058] Please refer to Figure 7 As shown, the main difference between this embodiment and the first embodiment is that the portable micro-tiller in this embodiment also includes a sliding baffle 6. For other structures, please refer to the first embodiment, which will not be described again here.

[0059] As shown in the figure, in this embodiment, the portable micro-tiller also includes a sliding baffle 6. The sliding baffle 6 includes a base plate 61 and a baffle 62. The base plate 61 is disposed on the outer side of the first housing 14 and the outer side of the second housing 15. The baffle 62 is connected to the base plate 61 and can slide up and down relative to the base plate 61.

[0060] In this embodiment, the base plate 61 is installed on the outside of the first housing 14 and the outside of the second housing 15, and a vertical slide rail is provided on the side of the base plate 61 away from the first housing 14 or the second housing 15. A slider is provided on the baffle 62, and the slider is installed on the vertical slide rail and can slide up and down on the vertical slide rail, thus realizing the slidable connection between the base plate 61 and the baffle 62. When using the portable micro-tiller, the baffle 62 can slide up and down relative to the base plate 61 according to the undulation of the terrain during the forward movement, without hindering the loosening of soil by the rotary tiller blade 134 or the movement of the portable micro-tiller. At the same time, the two sliding baffles 6 on both sides can push away the branches and leaves extending between the two rows of crops to avoid contact with the rotary tiller blade 134, thus preventing the rotary tiller blade 134 from damaging the crops. Specific Implementation Example 4:

[0062] Please refer to Figure 8 As shown, the main difference between this embodiment and the first embodiment is that the portable micro-tiller in this embodiment also includes a cleaning brush 7. For other structures, please refer to the first embodiment, which will not be described again here.

[0063] like Figure 8 As shown, in this embodiment, the portable tiller also includes a cleaning brush 7, which is disposed on the front side of the rotary tiller blade 134. When the user pushes the portable tiller forward, the cleaning brush 7 contacts the soil surface before the rotary tiller blade 134, thereby sweeping away debris on the soil surface, such as leaves, stones, and grass roots, from the path of the rotary tiller blade, ensuring that the working soil area is relatively clean and reducing the possibility of debris getting tangled in the blade. This effectively cleans debris and ensures smooth soil loosening operations.

[0064] Specifically, high-strength, wear-resistant nylon brushes can be selected. Furthermore, a rotating brush can also be used, and the rotating brush is connected to the drive motor 11. The drive motor 11 drives the rotary tiller 134 to operate while simultaneously driving the rotating brush to rotate, so as to separate debris from the soil surface and sweep it to both sides of the path of the rotary tiller 134.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
