Abstract

The invention provides a sand sprayer. The sand sprayer comprises a main body; a sand storage chamber is formed in the main body; the sand storage chamber is provided with a sand flow hole which is used for discharge of sand in the sand storage chamber; a channel corresponding to the sand flow hole is formed in the main body; a moving part capable of performing linear reciprocating motion and realizing opening and closing of the sand flow hole is arranged in the channel via sealing sleeving connection. The sand sprayer also comprises an eccentric rotating part, and a motor capable of driving the eccentric rotating part to rotate; the eccentric rotating part is contacted with the moving part, and is used for driving the moving part to perform linear motion; the machine body of the motor isfixedly connected with the main body; and the power output end of the motor is fixedly connected with a rotating shaft of the eccentric rotating part. The sand sprayer is capable of realizing accuratecontrol on sand discharge amount.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle sand spreading equipment, and in particular relates to a sand spreading device. Background technique [0002] Due to the influence of rain, snow, frost, etc. during the operation of rail vehicles, wheel skid problems will occur. However, wheel skidding will bring great harm to the operation of the vehicle: the light ones will scratch the wheels, and the severe ones will prolong the braking distance, which will cause safety accidents. Therefore, in order to ensure the safe operation of the vehicle, a sand spreading device is provided to effectively improve the adhesion between the wheel and the track, thereby reducing the risk of sliding of the rail vehicle. [0003] Chinese invention patent CN103318191B discloses an automatic sand spreading device. The bottom plate of the sand box is connected to the top plate of the sand spreading box and the top of one side of the support plate of the powe...
