AI Technical Summary
Traditional compaction presses suffer from problems when operating on uneven fields, such as uneven compaction density, difficulty in flexibly adjusting posture, easy collision with obstacles and interruption, fixed compaction width, and large space occupation when not in operation.
The self-propelled compactor adopts a steering and compaction mechanism, which includes a main compaction component, an auxiliary compaction component, and a steering component. Through the up-and-down swing of the main compaction component, the free movement of the auxiliary compaction component, and the angle adjustment of the hydraulic cylinder, the soil can be uniformly compacted, flexibly adjusted, and its width can be adjusted.
It improves the uniformity and stability of soil compaction density, enhances the flexibility and adaptability of the compactor, increases operating efficiency, avoids interruptions due to obstacle collisions, and reduces the space occupied by the equipment.
