Problems solved by technology
However, there are many problems in the use of high-branch saws in the prior art, which are specifically manifested in the following aspects: 1. Sawdust will be generated during operation, and the sawdust is easy to fall in the air, and even fall into the eyes of the operator, affecting the operation ; Two, in the process of sawing larger branches, it is easy to cause the bark to tear during the falling of the branches, causing secondary injuries to the tree and expanding the wound of the tree; three, during the operation, the operating personnel It is necessary to overcome the large reaction force during the operation of the saw blade

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] High branch saw provided by the invention, such as Figure 1-8 As shown, it includes a handle 1 and an annular saw blade 2 located at one end of the handle 1, and also includes an outer cover 3 located on the outer side of the annular saw blade 2 and arranged around the annular saw blade, between the outer cover 3 and the annular saw blade 2 There is a gap for the flow of sawdust. The outer cover 3 is provided with a bayonet 4 for exposing part of the circular saw blade 2 to contact with the branches to be sawed. The outside of the outer cover 3 is also provided with a net cover 5 for collecting sawdust. The outer cover 3 is connected to the net. There is a channel for the flow of sawdust between the covers 5; a position adjustment member is provided between the outer cover and the handle, and the position adjustment member can be adjusted so tha...

The invention provides a high-branch saw and a sawing method for branches, which includes a handle and a circular saw blade located at one end of the handle, and also includes a cover located on the outside of the circular saw blade and arranged around the circular saw blade. The gap between the cover and the circular saw blade is There is a gap for the flow of sawdust in between, and the outer cover is provided with a bayonet for exposing part of the circular saw blade to contact with the branches to be sawed, and the outside of the outer cover is also provided with a net cover for collecting sawdust. There is a channel for the sawdust to flow; a position adjustment piece is also arranged between the outer cover and the handle. The invention solves the problem of flying sawdust during the operation of the high-altitude saw, optimizes the working environment, effectively reduces the reaction force of the saw blade on the human body during the operation of the high-altitude saw, and solves the problem of the large branches on the bark when sawing and falling. The problem of tearing, avoid causing larger wounds to the tree.
Description
【Technical field】 [0001] The invention belongs to the technical field of forestry and garden maintenance equipment, and in particular relates to a high-branch saw and a sawing method for branches. 【Background technique】 [0002] High branch saw refers to high branch pruning saw, which is one of the commonly used garden machines for pruning trees in landscaping. However, there are many problems in the use of high-branch saws in the prior art, which are specifically manifested in the following aspects: 1. Sawdust will be generated during operation, and the sawdust is easy to fall in the air, and even fall into the eyes of the operator, affecting the operation ; Two, in the process of sawing larger branches, it is easy to cause the bark to tear during the falling of the branches, causing secondary injuries to the tree and expanding the wound of the tree; three, during the operation, the operating personnel It is necessary to overcome the relatively large reaction force during ...
