It is exported all the way by the second sand inlet 21 from the second sand export 22, so as to guarantee before rail vehicle gauge is changed
Afterwards, enough sands are sprayed between wheel track；
Preferably, if the spacing of the first sand export 12 and the second sand export 22 is S, and the first round of wheel pair is set away from as X1,
And the second wheelspan of wheel pair is set as X2, thenIt may also be said that the first sand export 12 and the second sand export 22
Line space design is the half that rail vehicle becomes gauge difference before and after rail；
For to first shake out channel 10 and second shake out 20 sand supplying of channel mode, can be with are as follows: such as Fig. 1 and Fig. 2 institute
Show, the unit that shakes out of the embodiment of the present application further includes sand filling passageway 30, and sand filling passageway 30 has third sand export 31, and third is shaked out
Mouthfuls 31 contact and communicate with the first sand inlet 11 and the second sand inlet 21, so that sand is concentrated after sand filling passageway 30 to the
One sand inlet 11 and the output of the second sand inlet 21, thus guarantee first shake out channel 10 and second shake out channel 20 have it is more steady
Fixed efficiency of shaking out；
It shakes out channel 10, the second generation type for shaking out channel 20 and sand filling passageway 30 for first, it can be with are as follows: as schemed
Shown in 1 and Fig. 2, the unit that shakes out further includes support substrate 40 and nozzle 50, and support substrate 40 is used to support nozzle 50, nozzle 50
One end is fixedly connected with support substrate 40, and sand filling passageway 30, first shake out channel 10 and second channel 20 that shakes out is both formed in spray
In mouth 50, channel 10 and second shake out channel 20 to guarantee that sand concentration is delivered to first and shakes out, the first sand export 12 and the
Two sand exports 22 are located at the other end of nozzle 50；Specifically, support substrate 40 is the stucco mouth blast tube of sander, nozzle
50 be in Y type, and nozzle 50 is locked in the end of stucco mouth blast tube by hose clamp, so that the installation and replacement of nozzle 50 are convenient,
Nozzle 50 is integrally formed by the vulcanization of rubber, consequently facilitating forming the tandem product for being suitable for different gauge changings, first shakes out
Channel 10 and second shake out channel 20 smooth-sided transition, to reduce the obstruction to sand, first shakes out channel 10 and second
The channel 20 that shakes out preferably is symmetrically set, and more specifically, there are a symmetrical plane, which passes through sand filling passageway
30, the symmetrical plane is parallel with sand filling passageway 30, and sand filling passageway 30 is symmetrical relative to the symmetrical plane, first shake out channel 10 with
Second channel 20 that shakes out is symmetrical relative to the symmetrical plane, with this, ensure that from the first sand export 12 and the spray of the second sand export 22
Sand amount out is essentially the same, in addition, the embodiment of the present application, by the way that nozzle 50 is arranged, in practical application, by nozzle 50
Installation control can expeditiously guarantee that first shakes out channel 10 and second channel 20 that shakes out is respectively aligned to wheel track region.
Based on above-mentioned, the application at least have the following technical effects or advantages:
Embodiments described herein by setting first shake out channel 10 and second shake out 20 two, channel shake out it is logical
Road, while two channels that shake out can be correspondingly arranged from the track with different gauges respectively, when shaking out, sand shakes out logical from two
Road output, to there are enough sands to be sprayed between wheel track in the changed front and back of rail vehicle gauge, to solve
How when gauge changes, the technical issues of guarantee between sand can be effectively sprayed to wheel track, and then improve logical
Cross the wheel track Efficient Adhesive Promotion of stucco generation.
Illustrate the application in order to clearer, below with regard to the list that shakes out in the application by taking Fig. 1-embodiment shown in Fig. 4 as an example
The installation and the course of work of member are illustrated:
By installation control, guarantee nozzle 50 first shake out channel 10 and second shake out channel 20 can be located separately wheel change
Front before and after rail is simultaneously directed at wheel track region
Nozzle 50 is locked in the end of stucco mouth blast tube, the inner hole of sand filling passageway 30 and stucco mouth blast tube by hose clamp
Connection.
When the work of vehicle sander, sand flows into sand filling passageway 30 by blast tube, in 50 inside sand flow of nozzle point
Channel 10 is shaked out from first for two parts and respectively and second channel 20 that shakes out sprays, and due to the symmetric design in structure, is guaranteed
Shake out from two channel ejection sand amount it is essentially the same, the sand of ejection can be respectively acting between the wheel track before and after becoming rail with
Improvement is sticked together.
