XW90 Horizontai Drum Cutter

The XW milling and excavating machine can be installed on any type of hydraulic excavator, efficiently replacing general configurations such as digging buckets, crushing hammers, and hydraulic shears. It is applied in multiple fields such as open-pit coal mines, tunnel excavation and contour correction, channel groove milling, asphalt concrete pavement milling, rock permafrost milling, and tree root milling. The milling and excavating machine provides a new construction method for tunnel excavation.

Features of XW milling and excavation machine:

1. Wide range of milling and excavation;

2. Low vibration and low noise;

3. Accurately control construction;

4. The material excavated by milling has a small and uniform particle size, which can be directly used as backfill material;

5. Good safety;

6. Simple structure and convenient use.

The key of milling and digging machine consists of oil motor, transmission device and milling and digging head. As the implementation component, the milling head of the longitudinal milling and digging machine is one of the most important components of the milling and digging machine. The structure of milling and digging head mainly includes three parts: milling and digging hub, milling and digging knife and milling and digging knife block, in which milling and digging knife is a part of the raw materials involved in milling and digging, its reasonable layout and structural parameters immediately harm the activity and dynamic model performance of milling and digging machine, so it becomes the main and key content of the design scheme of milling and digging head: At the same time, because of the diversity of milling and digging processing technology, this part of the design is also a difficult problem in the design of milling and digging head.

In this paper, the mining longitudinal milling and digging machine milling head as a scientific research prototype, according to the basic mapping engineering of the original records obtained, first from the theoretical analysis and design of the rational layout of the milling and digging tool completed: Thus, dynamic model simulation is used to systematically study the performance of milling and digging machine. Finally, the cutting Angle, radial interval of sharp tool and other important geometric parameters are improved. Further simulation results show that the performance of milling and digging head has been greatly improved.
