AI Technical Summary
Technical Problem
Existing sand spreading devices suffer from uneven sand spreading and sand deposition, which affects the control of track adhesion.
Method used
The system employs a combination of a pneumatic motor, a reducer, and a spiral auger. The pneumatic motor drives the spiral auger to output sand in a measured quantity, and multiple distribution compartments are set in the distribution box for even distribution. A sealing cylinder plate is used to prevent sand blockage.
Benefits of technology
It achieves uniformity and reliability in sand conveying, improves the adhesion coefficient between wheel and rail, avoids slippage, and enhances the accuracy of sand output and the reliability of the device.
