Description

Technical Field

[0001] The invention relates to the field of logging, in particular to a bamboo delimbing feller. Background Art

[0002] Bamboo is a widely distributed species in my country and is used in many aspects, but the problem of felling has always been a difficult problem to solve, which will significantly affect many subsequent work.

[0003] When non-professionals are cutting bamboo, it is difficult for them to use traditional machetes flexibly and efficiently, as it consumes a lot of manpower and has a high time cost. At the same time, modern electric saws are not easy to carry, are limited by power supply, and are heavy, making them difficult to carry during long working hours. These factors make it difficult to meet the needs of saving time and effort, and being convenient and easy to carry.

[0004] Different bamboos have different diameters, and wrapped felling tools need to be suitable for bamboos of different diameters.

[0005] Therefore, the present invention is directed to the above-mentioned problem and proposes a bamboo debranching felling device, which can also be used for removing side branches. Summary of the Invention

[0006] In order to make up for the above shortcomings, the present invention provides a bamboo debranching felling device that overcomes the above technical problems and can remove side branches.
