Abstract

It the utility model is related to a kind of engineering machinery engine exhaust structure, including engine exhaust tail pipe, muffler tail pipe, also include deflector, osculum, the deflector is cone, top is arranged on muffler tail pipe, bottom is fixedly mounted on engine exhaust tail pipe, and the osculum is opened on tailpipe, less than muffler tail pipe top；The utility model beneficial effect is：No rain-proof hat type blast pipe ponding damage engine and accessory are effectively prevent, reaches the purpose of Quick drainage.

Description

A kind of engineering machinery engine exhaust structure

Technical field

It the utility model is related to a kind of engine, more particularly to a kind of engineering machinery engine exhaust structure.

Background technology

The gas extraction system effect of engine is while ensureing engine optimum performance, all exhaust, safeties to be transported out of hair Motivation is simultaneously undisturbedly discharged in air；Gas extraction system cuts down exhaust noise to meet regulation and client couple by being equipped with muffler Noise requirements, under nominal situation, gas extraction system must be able to prevent completely the muddy water for coming from road surface splashing, rainwater, cleaning or its The water in his source enters engine body or turbocharger, especially protection post processing annex and related sensor；Exhaust tail Pipe main function is to ensure the smooth of exhaust and stop extraneous destruction, the presence or absence of commonly uses rain-proof hat type and with rain-proof hat type.

Tailpipe without the rainhat infrastructure cost is low, and technique is simple, convenient installation.But due to without rainhat and leading In flow structure, rainy day and other more water conditions, it is possible to water be present and flowed into along inner wall of liner inside engine and muffler, to it Cause the situation of damage；Tailpipe with rainhat：The structure can play the effect of waterproof dustproof, usual high-power engineering machine Tool is more conventional.But rainhat needs tail gas to overcome its Action of Gravity Field to open and close, it is possible to which rainhat be present can not open Situations such as opening, can not closing causes water to flow into muffler and ejection system, causes to damage；Both the above scheme is without anti-scald simultaneously Measure, during maintaining, it is likely to there is a situation where to cause operating personnel to touch scald by mistake.

Utility model content

The utility model solve technical problem be：Tailpipe without rainhat is intake and causes engine and its annex The problem of damaged condition and personnel's maloperation are scalded.

The utility model is to solve the technical scheme that is provided of above-mentioned technical problem：

A kind of engineering machinery engine exhaust structure, including engine exhaust tail pipe, muffler tail pipe, in addition to water conservancy diversion Plate, osculum, the deflector are cone, and top is arranged on muffler tail pipe, and bottom is fixedly mounted on engine exhaust tail Guan Shang, the osculum are opened on tailpipe, less than muffler tail pipe top；Deflector coning, to bottom incline by top Tiltedly, after the liquids such as water enter tailpipe, engine body exterior is flowed out by osculum, while without using there is rain-proof cap to prevent Waste gas overflows from osculum.

The draining hole site is corresponding with deflector terminal position, and when ponding flows into deflector, fast and easy passes through Osculum is emptied.

Also include anti-scald plate, the anti-scald plate is fixedly mounted on tailpipe, and the anti-scald plate is bolted, side Just maloperation and dismounting.

The utility model beneficial effect is：No rain-proof hat type is effectively prevent by the setting of deflector and osculum to arrange Tracheae ponding damages engine and accessory, reaches the purpose of Quick drainage, while anti-scald plate prevents the purpose of maloperation.

Brief description of the drawings

Fig. 1 is a kind of engineering machinery engine exhaust structure schematic internal view；

Fig. 2 is anti-scald plate schematic view of the mounting position

Wherein, 1, engine exhaust tail pipe, 2, muffler tail pipe, 3, deflector, 4, osculum, 5, anti-scald plate.

Embodiment

Referring to the drawings, engine exhaust tail pipe 1 is enclosed on the outside of muffler tail pipe 2 in the utility model, between pass through installation There is deflector 3, the upper end of conical deflector 3 is fixed on muffler tail pipe 2, and lower end is fixed on engine exhaust tail pipe 1 On, osculum 4 is provided with the relative engine exhaust tail pipe 1 in the tendency face of deflector 3, is pacified outside engine exhaust tail pipe 1 Encounter the anti-scald plate 5 of tail pipe equipped with maintenance personal's maloperation is prevented.

When the liquids such as rainwater are carried out such as without rainhat engine exhaust tail pipe 1, typically water can be worked as along tube wall to flowing down Flow to after deflector 3 by the body outside the outflow engine exhaust of osculum 4 tail pipe 1, it is therefore prevented that water is to engine interior Damage.

Claims

1. a kind of engineering machinery engine exhaust structure, including engine exhaust tail pipe, muffler tail pipe, it is characterised in that：Also Including deflector, osculum, the deflector is cone, and top is arranged on muffler tail pipe, and bottom, which is fixedly mounted on, starts On machine tailpipe, the osculum is opened on tailpipe, less than muffler tail pipe top.

A kind of 2. engineering machinery engine exhaust structure according to claim 1, it is characterised in that：The draining hole site It is corresponding with deflector terminal position.

A kind of 3. engineering machinery engine exhaust structure according to claim 1, it is characterised in that：Also include anti-scald plate, The anti-scald plate is fixedly mounted on tailpipe.

A kind of 4. engineering machinery engine exhaust structure according to claim 3, it is characterised in that：The anti-scald plate passes through Bolt is fixed.
