Description

Technical Field

[0001] This utility model relates to the field of bamboo felling equipment technology, and in particular to a portable lithium-ion powered bamboo felling chainsaw. Background Technology

[0002] In existing technologies, general-purpose chainsaws used for cutting wood are typically used for cutting bamboo. While existing general-purpose chainsaws (such as lithium-ion chainsaws or chainsaws) can cut wood quickly, when cutting bamboo, the chainsaw suffers from problems such as large guide plates and chains, wide kerf, low rotation speed, and insufficient power matching. In addition, because bamboo is hollow and has strong longitudinal fiber toughness, the cutting speed is slow, the chainsaw is prone to jamming, and the cut surface is uneven, which can easily cause tearing of the bamboo wall, greatly affecting the cutting quality.

[0003] In addition, due to the weight of ordinary wood chainsaws, their large guide plates, and wide chains, they consume a lot of energy. In bamboo forests with high mountains, deep valleys, and steep slopes, they are inconvenient to operate, require a lot of labor from the operators, and pose a high safety risk.

[0004] Therefore, there is an urgent need for a portable lithium-ion battery-powered bamboo chainsaw specifically designed for bamboo felling operations to improve cutting speed, reduce saw jamming, improve the smoothness of the cut surface, reduce tearing of the bamboo wall surface, and improve cutting quality.

[0041] Please refer to the attached document. Figure 1 To be continued Figure 7 As shown, an embodiment of this utility model provides a portable lithium-ion powered bamboo-cutting chainsaw, including a saw body 10. The saw body 10 includes a guide plate 11, a saw chain 12, and a drive device. The guide plate 11 is disposed at the front end of the saw body 10, and the saw chain 12 is wound around the outer periphery of the guide plate 11. The drive device is used to drive the saw chain 12 to rotate along the outer periphery of the guide plate 11. The saw chain 12 includes multiple drive chain segments 121, multiple cutting chain segments 122, multiple connecting segments 123, and a chain shaft 124. Among them, the multiple drive chain segments 121 are arranged in pairs at intervals; the multiple cutting chain segments 122 are respectively connected between two adjacent drive chain segments 121, and the two adjacent cutting chain segments 122 are alternately distributed on opposite sides of the drive chain segments 121; the multiple connecting segments 123 are respectively located on opposite sides of the multiple cutting chain segments 122; the chain shaft 124 is used to connect the cutting chain segments 122, drive chain segments 121, and connecting segments 123 together.

[0042] In this embodiment, the saw chain 12 includes multiple drive chain segments 121, multiple toothed chain segments 122, multiple connecting segments 123, and a chain shaft 124. The drive chain segments 121 are spaced apart in pairs. The multiple toothed chain segments 122 are connected between adjacent drive chain segments 121, and adjacent toothed chain segments 122 are alternately distributed on opposite sides of the drive chain segments 121. The multiple connecting segments 123 are located on opposite sides of the multiple toothed chain segments 122. The chain shaft 124 connects the toothed chain segments 122, drive chain segments 121, and connecting segments 123 together. This design, by alternately distributing the multiple toothed chain segments 122 on opposite sides of the multiple drive chain segments 121, makes the arrangement of the toothed chain segments 122 on the multiple drive chain segments 121 more compact, forming a close tooth pitch. This results in a larger effective cutting area, increased sawing speed, reduced sawing resistance and rebound force, and reduced positive pressure required during sawing, making it easier to hold and more convenient to operate. By optimizing the arrangement of the cutting teeth chain 122, the size of the guide plate 11 and the saw chain 12 is reduced, shortening the saw kerf. This not only increases the chainsaw's rotational speed but also reduces equipment weight and energy consumption. This portable lithium-ion battery-powered bamboo-felling chainsaw is better suited to the hilly bamboo-growing areas of southern China, characterized by high mountains, deep valleys, and steep slopes. It effectively reduces operator workload, improves work efficiency, and lowers safety risks. Furthermore, this portable lithium-ion battery-powered bamboo-felling chainsaw effectively reduces saw jamming, improves the smoothness of the cut surface, reduces tearing of the bamboo wall surface, and enhances cutting quality.

[0043] In some optional embodiments, the toothed chain link 122 is configured as an anti-rebound toothed chain link. Compared with conventional toothed chain links, the anti-rebound toothed chain link can effectively reduce the rebound phenomenon that may occur during operation, and improve the safety and stability of operation.

The connecting base 21 is rotatable relative to the adjustable telescopic rod 20, allowing the angle of the saw body 10 to be adjusted as needed, enabling the operator to better control the cutting angle and improving operational flexibility and precision. The angle adjustment range of the saw body 10 is 0 to 30°, but is not limited to this.

[0051] In some optional embodiments, to ensure a stable connection between the battery mounting base 13 and the connecting base 21, a locking buckle 22 is provided on the connecting base 21 to lock the battery mounting base 13 onto the connecting base 21. When disassembly is required, the operator can simply operate the locking buckle 22 to remove the battery mounting base 13 from the connecting base 21.

[0052] In some alternative embodiments, a handle 23 is connected to the rear end of the adjustable telescopic rod 20, and the adjustable telescopic rod 20 is rotatable relative to the handle 23. The range of rotatable angle of the adjustable telescopic rod 20 relative to the handle 23 is 0-90°, but is not limited thereto.

[0053] In some optional embodiments, a start button 231 is provided on the handle 23 to facilitate quick start of the saw body 10 by the operator. A battery mounting part 232 is provided at the rear end of the handle 23 for mounting a lithium battery. The lithium battery serves as a power source, providing power to the saw body 10 when the adjustable telescopic rod 20 is used. Of course, the power source is not limited to the lithium battery installed in the battery mounting base 13 or the battery mounting part 232; it can also be connected to a battery backpack to provide power to the bamboo-cutting chainsaw.
