Description
Technical field
The utility model belongs to corn picker technical field, more particularly to a kind of corn picker silencer with eliminate the noise
Device tail pipe attachment structure.
Background technology
At present, corn picker silencer is connected in most cases using common plug-in type scheme with muffler tail pipe, disappears
Sound device escaping pipe external diameter is fixed as tail pipe internal diameter using clip；But in practical set by manual assembly factor influenceed compared with
Greatly, cause tail pipe to insert silencer length length to be difficult to control；And easily rocked after work long hours work.Now enter for this problem
Row design optimization is improved, and purpose is for convenience of fixed muffler tail pipe.
The content of the invention
The utility model provides a kind of simple structure, the side of installing and using to solve technical problem present in known technology
Just operating efficiency, is improved.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of corn picker silencer and muffler tail pipe attachment structure, including silencer and muffler tail pipe, it is special
Levy and be：Vertical on the silencer to be provided with escaping pipe, one end of the muffler tail pipe is exhaust outlet, muffler tail pipe it is another
One end is by clamp connection escaping pipe, and the muffler tail pipe and muffler outlet piper connection end are provided with reduction nipple, described
The external diameter of reduction nipple is more than the external diameter of muffler tail pipe, and the internal diameter of the reduction nipple is interior more than muffler tail pipe
Footpath, positioning table is formed in reduction nipple and muffler tail pipe inwall.
The utility model can also use following technical measures：
The reduction nipple is along the circumferential direction provided with pretension notch.
The height of the reduction nipple is 65mm.
The reduction nipple is formed with muffler tail pipe integrated punching；
The reduction nipple uses welding structure with muffler tail pipe.
The utility model has the advantages and positive effects that：Because the utility model uses above-mentioned technical proposal, that is, exist
Reduction nipple is set up in the end of muffler tail pipe, and positioning table is formed in reduction nipple and muffler tail pipe inwall, so disappears
The depth of sound device tail pipe insertion muffler outlet piper is consistent, so as to improve the uniformity of assembling；It is fixed reliable, long working
Tail pipe fastening afterwards will get well compared to common plug-in type scheme.In addition, the utility model also has simple structure, reasonable in design, raising
The advantages of efficiency of assembling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is I portions enlarged drawing in Fig. 1；
Fig. 3 is muffler tail pipe structural representation.
In figure：1st, silencer；1-1, escaping pipe；2nd, muffler tail pipe；2-1, exhaust outlet；3rd, clip；4th, reduction nipple；
4-1, positioning table；4-2, pretension groove.
Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Refer to Fig. 1 to Fig. 3, a kind of corn picker silencer and muffler tail pipe attachment structure, including silencer 1 with
Muffler tail pipe 2, vertical on the silencer 1 to be provided with escaping pipe 1-1, one end of the muffler tail pipe 2 is exhaust outlet 2-1,
The other end of muffler tail pipe connects escaping pipe 1-1 by clip 3, and the muffler tail pipe 2 and muffler outlet piper 1-1 are connected
End is provided with reduction nipple 4, the external diameter of the external diameter more than muffler tail pipe of the reduction nipple, the reduction nipple it is interior
Footpath forms positioning table 4-1 more than the internal diameter of muffler tail pipe in reduction nipple and muffler tail pipe inwall.
In order to improve the pretension intensity of clip, increase the bonding strength of muffler tail pipe and muffler outlet piper, the change
Footpath pipe joint is along the circumferential direction provided with pretension notch 4-2.
In order to improve the uniformity of assembling, the height of the reduction nipple is 65mm.
For the reduction nipple and the bonding strength of muffler tail pipe, the reduction nipple and muffler tail pipe of raising
Integrated punching is formed；The reduction nipple can also use welding structure with muffler tail pipe.
Using above-mentioned technical proposal, i.e., reduction nipple is set up in the end of muffler tail pipe, reduction nipple and disappeared
Sound device inner wall of liner forms positioning table, and the depth of such muffler tail pipe insertion muffler outlet piper is consistent, so as to improve dress
The uniformity matched somebody with somebody；Fixed reliable, tail pipe fastening will get well compared to common plug-in type scheme after long working.In addition, this practicality is new
Type also has simple structure, reasonable in design, the advantages of improve efficiency of assembling.
The above is only, to preferred embodiment of the present utility model, not to make any formal to the utility model
Limitation, it is every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations with
Modification, belongs in the range of technical solutions of the utility model.
