| titleOfInvention | Compound classification crushing pipe jacking machine |
| abstract | The utility model relates to a composite grading and crushing pipe jacking machine. The composite grading and crushing pipe jacking machine includes a soil bin cylinder, a cutter head, a drive assembly, an inner crushing cone and an outer crushing cone. The cutter head is arranged at the front end of the soil bin cylinder. A plurality of mud feeding openings are opened on the upper part. The driving assembly includes a driving part and a main shaft connected to the driving part. The inner crushing cone is arranged in the soil bin and fixed on the main shaft. The composite pipe jacking machine can easily control the particle size of the pebble and gravel within the dischargeable range, and has a strong stirring function, and has a high construction efficiency for the pebble and gravel soil body, and it is difficult for the machine to discharge mud for the silty clay. The mouth is blocked or the ground is raised due to poor mud discharge. |
