Description

Technical Field

[0001] The utility model relates to the field of forestry engineering machinery, in particular to a special multifunctional forestry harvesting and shearing integrated accessory. Background Art

[0002] Felling is an important activity in forest and tree management, which is mainly divided into four types: main felling, tending felling, renewal felling and low-yield (efficiency) forest transformation felling. Among them, main felling includes three methods: clear felling, selective felling and gradual felling. Tending felling refers to the felling of some trees in the forest during the period from the closure of young forests to the age class before the felling (main felling) of mature forests. Forest tending is the main means and an important part of forest cultivation. In a broad sense, renewal felling includes stand renewal felling and forest belt renewal felling.

[0003] Felling for stand renewal mainly includes thinning, selective felling and diameter-selective felling, while felling for belt renewal mainly includes full-belt felling, broken-belt felling and branch felling. However, the felling head structure technology may not be widely used in China at present, or the main door structure is rarely used. This situation has certain problems, such as low work efficiency and single function.

[0004] In response to these problems, we have improved the existing portal main structure felling head to enhance its working efficiency and functional diversity. This improvement is intended to provide more efficient and practical technical support for my country's forest and tree management, and further promote the sustainable development and utilization of forest resources.
