Lightened garden pneumatic saw

Abstract

The invention discloses a lightened garden pneumatic saw. The lightened garden pneumatic saw comprises a back box, a corrugated hose and a saw box, wherein a storage battery and a high-pressure air blower are fixedly connected in the back box; the left end of the saw box is fixedly connected with a back handle; the upper end of the saw box is fixedly connected with an upper handle; both the back handle and the upper handle have telescopic structures constructed by slide nesting of a fixed handle and a movable handle; a wind disk is fixedly connected in the saw box; a wind wheel is rotationally connected in the wind disk; the two sides of the lower part of the wind disk are communicated with an air inlet tube and an air outlet tube led out of the saw box; a rotation shaft of the wind wheel is led out of the wind disk and is fixedly connected with a driving chain wheel; the right part of the saw box is rotationally connected with a driven chain wheel; a saw chain is arranged between the driving chain wheel and the driven chain wheel. The handheld operating part has the advantages of light weight, low vibration, convenience in use, high accuracy, avoidance of fatigue after long-term use, convenience in maintenance and replacement, adjustable extension length and higher user friendliness.

Description

technical field [0001] The invention relates to garden equipment, in particular to a lightweight garden pneumatic saw. Background technique [0002] Garden pruning is an indispensable work in urban construction. It prunes the trees used for urban greening into various special shapes that may be neat or funny. Saws and chainsaws, among which high-branch saws are mainly used for large-scale rough pruning, while electric saws are used for fine trimming. Their joint cooperation saves a lot of time and labor in garden pruning. However, chainsaws are used as general products. , it is less pertinent to garden pruning, and there are many shortcomings in actual use. First, as a highly integrated mechanical device, its structure is complex, and it is troublesome to replace the saw chain of the wearing parts. Difficult. Secondly, the weight is heavy.

[0002] Garden pruning is an indispensable work in urban construction. It prunes the trees used for urban greening into various special shapes that may be neat or funny. Saws and chainsaws, among which high-branch saws are mainly used for large-scale rough pruning, while electric saws are used for fine trimming. Their joint cooperation saves a lot of time and labor in garden pruning. However, chainsaws are used as general products. , it is less pertinent to garden pruning, and there are many shortcomings in actual use. First, as a highly integrated mechanical device, its structure is complex, and it is troublesome to replace the saw chain of the wearing parts. Difficult. Secondly, the weight is heavy. Under the premise of ensuring the effective cutting length, the weight of the current chainsaw is about six to seven kilograms. The main motor takes up too much weight. Increased work intensity not only affects the accuracy of pruning, but also can easily lead to safety accidents when using this high-risk equipment in a fatigued state; again, because of its complex structure, its cutting extension length cannot be adjusted, and it is still difficult to prune roadside trees. Good, but when trimming the trees in the middle position, it is often necessary to reach into the bushes, which is very troublesome; finally, it relies on the electric motor to drive, and the vibration is large during use, which affects the operation accuracy

The above shortcomings are particularly prominent when the chainsaw is used in garden pruning, and it is urgent to solve
