Semi-automatic chain saw capable of reducing noise

Abstract

The invention discloses a semi-automatic chain saw capable of reducing noise, and relates to the technical field of chain saws. The semi-automatic chain saw comprises a shell, a detection mechanism is fixedly connected to the inner wall of the top of the shell and plays a role in judging whether the chain saw is in a lubricating oil lacking state or not, an adding mechanism is fixedly connected to the inner wall of the shell and is close to the bottom of the detection mechanism, and the adding mechanism plays a role in adding lubricating oil. According to the semi-automatic chain saw capable of reducing the noise, through cooperative use of the detection mechanism and the adding mechanism, by means of the working state of the equipment, when the lubricating oil lacks, an equipment body shakes violently, a damping block in the detection mechanism converts mechanical energy into heat energy, gas in a gas film is subjected to thermal expansion, a movable contact makes contact with a fixed contact, the adding mechanism is electrified to realize the effect of automatically adding the lubricating oil, and therefore the effect of automatic judgment is achieved. Compared with an existing chain saw, the automatic judgment effect is added, the problem that the chain saw lacks lubrication is effectively solved in time, and practicability is improved.

Description

technical field [0001] The invention relates to the technical field of chainsaws, in particular to a noise-reducing semi-automatic chainsaw. Background technique [0002] Chain saws, also known as chain saws, are portable saws powered by gasoline engines. They are mainly used for logging and timber production. Motorized chainsaws, non-motorized chainsaws, etc. During the use of current chainsaws, excessive noise often occurs, which seriously affects the user's sense of experience. [0003] The current chainsaw needs to use lubricating oil to lubricate the saw teeth frequently during use. If the lubrication is not carried out in time under the condition of long-term work, the friction between the saw teeth will be very large, causing the chain saw to vibrate violently , the most direct solution at this time is that noise will be generated during use, and the harm of noise is relatively small. The main reason is that the loss of the saw teeth is large, and it is easy to cause...

[0002] Chain saws, also known as chain saws, are portable saws powered by gasoline engines. They are mainly used for logging and timber production. Motorized chainsaws, non-motorized chainsaws, etc., the current chainsaws often have excessive noise during use, which seriously affects the user's sense of experience

[0003] The current chainsaw needs to use lubricating oil to lubricate the saw teeth frequently during use. If the lubrication is not carried out in time under the condition of long-term work, the friction between the saw teeth will be very large, causing the chain saw to vibrate violently , the most direct solution at this time is that noise will be generated during use, and the harm of noise is relatively small. The main reason is that the loss of the saw teeth is large, and it is easy to cause irreparable damage to the saw teeth, which reduces the chainsaw teeth. service life, reducing the usefulness of the chainsaw
