AI Technical Summary

Technical Problem

The existing seam filling equipment lacks a stirring device when using asphalt, resulting in uneven asphalt mixture and prone to segregation; in addition, the equipment can only perform linear seam filling operations in a single direction, and when encountering transverse cracks, it needs to be redirected, which is inefficient.

Method used

A highway subgrade maintenance pavement seam filling device is designed, equipped with a storage box, a rotating plate, agitating rod and a seam filling device. The asphalt is stirred and evenly conveyed through the motor drive system, and the lateral movement of the seam filling device is realized through the reciprocating screw and sliding block mechanism to adapt to cracks in different directions.

Benefits of technology

It effectively avoids the separation of asphalt during use, ensures the uniformity of the mixture, and improves the flexibility and working efficiency of the seam filling equipment, so as to handle transverse cracks more conveniently.
