Abstract
The invention discloses an exhaust silencer of a damping type engine. The exhaust silencer comprises an air inlet pipe, an expanding chamber, an exhausting pipe and a movable separation plate, wherein a damping plate which is matched with the wall of the expanding chamber along a vertical direction in a sliding manner is arranged inside the expanding chamber and is just aligned to the outlet of the air inlet pipe; a damping spring is arranged on one side, opposite to the outlet of the air inlet pipe, of the damping plate; the exhausting pipe penetrates through the damping plate and is matched with the damping plate in a sliding manner; and the movable separation plate is provided with a through resonant through hole. As the exhaust silencer adopts a structure of combining the damping plate with the movable separation plate, the size of an air inlet space is changed through bidirectional expansion of the damping plate and the movable separation plate when an engine is operated and the exhausting pipe of the silencer exhausts gas, so that operation noises of the engine can be effectively reduced, the vibration of the silencer can be relieved, and the noise pollution caused by the operation of the engine is reduced. The exhaust silencer of the damping type engine has a simple and compact structure and does not increase the manufacturing cost.
Description
Technical field
The present invention relates to a kind of universal machine parts, particularly a kind of engine exhaust system parts.
Background technique
Motor is the detonation generation power through oil plant, therefore, can produce bigger noise in the running; Particularly for general purpose engine, owing to easy to use, can be used for any occasion that needs power, adaptability is stronger; And in the practice, for comparatively concentrated residential quarters, residential belt, road maintenance etc., motor has played irreplaceable effect especially.And in the existing technology,, causing surrounding resident to enjoy the noise puzzlement for the control of noise and unsuccessful, the environment around the influence causes than serious environmental and pollutes.
For overcoming the above problems, existing engine exhaust system has adopted conventional muffler structure, though have certain sound deadening; But noise is still bigger; Particularly along with the raising of rotating speed, simultaneously, silencing apparatus is because the vibration that the exhaust frequency causes is also bigger; This shows that existing baffler does not improve to efficiency the noise pollution that the motor operation causes environment.
Therefore, need improve, can effectively reduce the running noises of motor existing engine exhaust system; And increase with engine speed; Can change the size of exhaust buffering, thereby realize effectively eliminating the noise and reducing vibration, reduce because the noise pollution that the operation of motor causes.
Summary of the invention
In view of this; The purpose of this invention is to provide a kind of damp type engine exhaust muffler; The running noises of motor can be effectively reduced, and, the size of exhaust buffering can be changed with the increase of engine speed; Thereby realize effectively eliminating the noise, reduce because the noise pollution that the operation of motor causes.
Damp type engine exhaust muffler of the present invention; Comprise suction tude, expansion cavity and outlet pipe; Over against the suction tude outlet damping plate that longitudinally is slidingly matched with the expansion cavity wall is set in the said expansion cavity, said damping plate is positioned at the relative side of suction tude outlet damping spring is set; Said outlet pipe passes damping plate and is slidingly matched with it;
The moveable partition board that also comprises the resonance through hole that has perforation; Said suction tude and outlet pipe pass moveable partition board respectively; The suction port apportion moveable partition board both sides of the air outlet of suction tude and outlet pipe; Said moveable partition board cooperates with axially displaceable mode with suction tude and outlet pipe, and the air inlet side that moveable partition board is positioned at outlet pipe is provided with return spring.
Said damping spring at least 3 so that the mode of damping plate producing balanced forces distribute; Wherein a damping spring is coated at outlet pipe.
Also comprise the discharger and the fixed plate that are positioned at expansion cavity, said fixed plate is positioned at the moveable partition board front side and the vent hole of crossing of perforation is set, and said outlet pipe passes stationary barrier forward, and said suction tude is passed stationary barrier and moveable partition board successively; Said discharger passes stationary barrier and moveable partition board successively and can move vertically with moveable partition board and cooperates.
Said return spring between stationary barrier and moveable partition board, return spring quantity and one by one corresponding be enclosed within outlet pipe, suction tude and discharger on corresponding with outlet pipe, suction tude and discharger.
Said return spring between stationary barrier and moveable partition board, return spring quantity and one by one corresponding be enclosed within outlet pipe, suction tude and discharger on corresponding with outlet pipe, suction tude and discharger.
The invention has the beneficial effects as follows: damp type engine exhaust muffler of the present invention; The structure that adopts damping plate and moveable bulkhead to combine is when motor moves, in the time of the exhaust of silencing apparatus suction tude; Two-way expansion through damping plate and moveable bulkhead; Change the size of admission space, can effectively reduce the running noises of motor and the vibration that can alleviate silencing apparatus, reduce because the noise pollution that the operation of motor causes; The present invention is simple and compact for structure, does not increase manufacture cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Accompanying drawing is a structural representation of the present invention.
Embodiment
Accompanying drawing is a structural representation of the present invention; As shown in the figure: the damp type engine exhaust muffler of present embodiment; Comprise suction tude 13, expansion cavity 4 and outlet pipe 16; Over against suction tude 13 outlets the damping plate 2 that longitudinally is slidingly matched with expansion cavity 4 walls is set in the said expansion cavity 4, said damping plate 2 is positioned at the relative side of suction tude 13 outlets damping spring 3 is set; Said outlet pipe 16 passes damping plate 2 and is slidingly matched with it;
The moveable partition board 5 that also comprises the resonance through hole 6 that has perforation; Said suction tude 13 is passed moveable partition board 5 respectively with outlet pipe 16; Suction port apportion moveable partition board 5 both sides of the air outlet of suction tude 13 and outlet pipe 16; Said moveable partition board 5 cooperates with axially displaceable mode with suction tude 13 and outlet pipe 16, and the air inlet side that moveable partition board 5 is positioned at outlet pipe 16 is provided with return spring.
Said damping spring 3 at least 3 so that the mode of damping plate 2 producing balanced forces distribute; Wherein a damping spring is coated at outlet pipe 16; Present embodiment is 3 distributions triangular in shape, makes the damping plate can producing balanced forces.
