Description
Technical field
The utility model is about engine art, especially with regard to a kind of harvester smoke exhaust pipe.
Background technique
The agricultural machinery harvester market segments are common have wheat harvester, corn picker, rice harvester, cotton harvester,
Potato harvester etc. gathers in the hot dry weather in season, the more heat of Tail Pipe Temperature are very according to the work characteristics of harvester itself
It is careless slightly extremely in red heat state heat, nigh combustibles (for example crop material) will be fallen and ignited, for After-treatment technics
Part-smoke exhaust pipe is more demanding.
On vehicle, smoke exhaust pipe is mounted on catalytic muffler the catalytic muffler of existing majority harvester, is then being arranged
Heat shield is wrapped up outside smoke pipe to be thermally shielded.Since external heat shield is fixed using extension spring-type or needle button, cause to discharge fume
The full package difficulty of pipe is big, and vibration may also lead to heat shield and loosen when work.Secondly, package heat shield crack is easy to fall into work outside
Object stalk, smoke evacuation tail pipe high temperature causes to ignite, or even burns vehicle.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing
Technology.
Utility model content
The purpose of this utility model is to provide a kind of simple and reasonable harvester smoke exhaust pipe, the harvester smoke exhaust pipes
To coat entirely on the fixed smoke exhaust pipe of type collet, and be conducive to smoke exhaust pipe arrangement, reduce the installation procedure of operator, reduce because
Heat shield loosens the failure for the combustibles that cause to ignite.
To achieve the above object, the utility model provides a kind of harvester smoke exhaust pipe, comprising: silencer connecting tube,
One end is connect with catalytic muffler, and the other end has smoke exhaust pipe socket；Smoke exhaust pipe, one end have expanding heterointerface, are used for
Be adapted to grafting with the smoke exhaust pipe socket of the silencer connecting tube, then by hose clamp, screw bolt and nut by silencer connecting tube with
Smoke exhaust pipe locking connects, and the tube body periphery on the upside of the expanding heterointerface offers external screw thread；And cladding is heat-insulated with type entirely
Set, is set on the smoke exhaust pipe, should have with one end inner circumferential of type collet and be adapted to the external screw thread of the smoke exhaust pipe
Internal screw thread.
In a preferred embodiment, silencer connecting tube and catalytic muffler are integrally formed.
In a preferred embodiment, expanding heterointerface offers multiple U-shaped openings.
In a preferred embodiment, multiple U-shaped openings are circumferentially uniformly opened up along the side wall of expanding heterointerface.
In a preferred embodiment, heat insulation foam built in expanding heterointerface.
Compared with prior art, harvester smoke exhaust pipe according to the present utility model has the following beneficial effects:
1, this programme will be coated entirely on the fixed smoke exhaust pipe of type collet, be conducive to smoke exhaust pipe arrangement, be reduced operator
Installation procedure, reduce and loosen the failure for the combustibles that cause to ignite because of heat shield.
2, silencer connecting tube is connect by this programme hose clamp with smoke exhaust pipe, and heat insulation foam built in heterointerface is played to larynx
Bind round heat-insulated effect, reduce hose clamp because the combustibles that ignite caused by the heat transfer high temperature of silencer connecting tube and smoke exhaust pipe therefore
Barrier.
3, the heterointerface of this programme smoke exhaust pipe can replace the size of hose clamp, meet silencer connecting tube difference ruler
Very little installation requirement.

Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
As shown in Figure 1, utilizing smoke-exhausting pipe of engine according to the harvester smoke exhaust pipe of the preferred embodiments of the present invention
Existing structure increases the post-processing catalytic muffler arrangement that conventional harvester can be widely used in type heat insulation structural.The receipts
The specific structure of cutting mill smoke exhaust pipe includes: hose clamp 1, silencer connecting tube 2, full cladding with type collet 5 and smoke exhaust pipe 6, wherein
Full cladding is set on smoke exhaust pipe 6 with the fixation of type collet 5, is conducive to smoke exhaust pipe arrangement, is reduced the installation procedure of operator,
It reduces because heat shield loosens the failure for the combustibles that cause to ignite.Silencer connecting tube 2 is connect with smoke exhaust pipe 6 by hose clamp 1, is arranged
Heat insulation foam built in the heterointerface of smoke pipe 6 plays the effect heat-insulated to hose clamp, reduces hose clamp because of silencer connecting tube and smoke exhaust pipe
Heat transfer high temperature caused by ignite the failures of combustibles.
Specifically, as shown in Fig. 2, silencer connecting tube 2 plays the role of connecting catalytic muffler, one end and catalysis
