Description
Technical field
The utility model belongs to a kind of silencing means, specially a kind of muffler on weeder.
Background technology
Muffler be prevent sound transmission and allow air-flow by a kind of device, be eliminate air power noise weight
Want measure.Muffler is mounted in air powered equipment（Such as air blower, air compressor machine, boiler exhaust mouth, generator, water pump row
The larger equipment of gas port noise）Gas channel on or inlet and exhaust system in reduction noise device.The type of muffler is very
It is more, but study carefully its noise elimination mechanism, and they can be divided into six kinds of main types, i.e. resistive muffler, resistant noise-reducing device, impedance
Complex deafener, microperforated panel muffler, aperture muffler and active muffler.
Grass trimmer be it is a kind of for cutting the grass on a lawn, the machine tool of vegetation etc..And its dynamical system, it is traditional with small size gasoline
Oil machine or the conventional combustion power system that diesel engine is representative.The characteristics of this dynamical system is：Power is larger, continue working when
Between it is long, but its it is maximum the disadvantage is that noise and vibrate it is larger, so needing the preferable muffler of performance to reduce the harm of noise.
Utility model content
The purpose of this utility model is to provide a kind of weeder trumpet type silencer, to reduce the noise of weeder.
In order to achieve the above object, the technical solution adopted in the utility model is：Including terminal pad, terminal pad is used for and mowing
Machine is fixed.The cylinder being fixedly connected is equipped in terminal pad, cylinder is the shell for waiting wall thickness.The top of the cylinder is equipped with out
Mouth pipe, bottom are equipped with inlet tube.Partition board equipped with multilayer parallel arrangement in the cylinder, partition board is equipped with venthole, so that empty
Gas passes through.It is weakened equipped with sound proof housing for stopping noise at the top of venthole.Sound proof housing is fixed on logical by lacing wire
The top of stomata；It is equipped with silencing cotton in cavity between partition board and partition board, further eliminates noise.
As a further improvement of the utility model, the bottom of the terminal pad be equipped with protrusion positioning step, be used for
Grass trimmer is attached.
As a further improvement of the utility model, the sound proof housing be it is intermediate it is protruding upward, etc. wall thickness arch
Shape is used for reflection sound wave, is further weakened to noise.
The outlet end of the outlet is horizontally disposed as a further improvement of the utility model, prevents outdoor sundries
Or rainwater is fallen into silencer.
The partition board is welded and fixed with cylinder inboard wall as a further improvement of the utility model,.
Be welded and fixed at the top of the outlet and cylinder as a further improvement of the utility model, it is described into
The bottom of mouth pipe and cylinder is welded and fixed.
The silencing cotton is two-component silencing cotton as a further improvement of the utility model, respectively polypropylene and poly-
Ester.Polypropylene is also known as PP, has excellent heat resistance, can be used for a long time at a temperature of 110 °.Fire protecting performance（Anti-flammability）It is non-
It is often good, life and device security can be effectively improved.
The beneficial effects of the utility model：Simple in structure, low production cost, and it is easy to use, fire-proof and water-proof goes dry effect
Fruit is good.Requirement that can also be according to user and applying working condition, adjust the quantity of partition board, to adjust the degree of noise reduction.
