The surface of track 8, the upper puddler and the lower puddler are laid in vertical, lay the upper of upper puddler in vertical
End is connected with the drive mechanism.
During actual use, the pressure sand spraying apparatus is arranged on the front end of the battery truck 7, can conveniently and efficiently carry out clear
Reason and maintenance.
During actual use, the quantity of the pressure sand spraying apparatus is identical with the quantity of track 8, ensures each battery truck
There is sand between 7 rails and the wheel of the battery truck 7, increase the adhesion strength between track 8 and the battery truck 7 wheel, have
Effect prevents the wheel of battery truck 7 from the phenomenon skidded occur.
During actual use, the setting of upper puddler and lower puddler, can be by the thin of shape of luming when upper puddler rotates
Sand is broken up, smashed, and after flowing down to lower puddler naturally under gravity, forces fine sand being transported to sand outlet, so as to
Ensure that fine sand is uniformly spread on track 8 from sand outlet, reduce and the hidden danger of car slipping security incident occurs because locomotive skids.
During actual use, the pressure sand spraying apparatus is arranged on by bolt on the housing of the front end of battery truck 7.
In the present embodiment, the drive mechanism is air motor 2.
In the present embodiment, the air motor 2 is connected with gas pipeline by snap joint 3, is set on the gas pipeline
It is equipped with pneumatic operated valve.
During actual use, the air compressor that is carried using the battery truck 7 introduces the gas after air is compressed
After body pipeline, the pneumatic operated valve is opened, makes the low speed of air motor 2, at the uniform velocity rotate, drives the upper puddler to be turned
It is dynamic, while exhaust side is to producing air pressure during the rotation of the air motor 2 in the sandbox 1, air pressure is to the fine sand in the sandbox 1
There is certain peptizaiton, the effect that realization that can be dual is broken up, smashed to the fine sand in the sandbox 1.
In the present embodiment, closure 6 is provided with the sand inlet.
During actual use, closure 6 is set effectively to ensure in the battery truck 7 in the course of work in the sand inlet
In, the scattered stone of institute's construction tunnel arch enters in the sandbox 1, causes not working to starter motor and upper puddler, meanwhile,
Effectively reduce humid air to enter in the sandbox 1, cause the fine sand phenomenon lumpd occur.
In the present embodiment, the upper puddler is circumferential including upper stirring bar body 4-1 and along the upper stirring bar body 4-1
The multiple stirring rod 4-2 laid from top to bottom, each stirring rod 4-2 are in horizontal layout, the length of the stirring rod 4-2
