In construction, excavator milling heads do a good job of handling basic problems in construction, such as concrete slabs and thick reinforced concrete walls. It can realize the multiple functions of hydraulic breaker and hydraulic tongs, while cutting steel bars in buildings. The material under milling has a very small particle size and can be used directly as recycled material. Grinders are very useful during the excavation of the following rock formations: - hard rock - weathered structured rock formations - solid layered rock formations, capable of drilling 80-120 tons per hour. Excavator milling head can well replace blasting construction and protect the environment. Other functions Milling asphalt mixture or cement concrete pavement can not only replace the expensive road excavator milling head, but also complete the deep processing of the road excavator milling head. The use of the excavator milling head can effectively remove obstacles such as rock formations, concrete structures, hard soil, frozen soil and tree roots during road subgrade construction.

The hydraulic excavator milling head is mainly composed of a hydraulic motor, a transmission device and an excavator milling head. Excavator milling head, as an executive component, is one of the main components of hydraulic excavator milling head. The structure of the hydraulic excavator milling head mainly includes the excavator milling head, the excavator milling head and the excavator milling head seat, where the excavator milling head directly participates in the material of the excavator milling head, its layout and structural parameters It is directly related to the motion and dynamic characteristics of the hydraulic excavator milling head, and has become the key and key content of the excavator milling head customization; due to the complexity of the excavator milling head process, this part of the design is also a part of the hydraulic excavator milling head The difficulty of customization.

Excavator milling heads play a very important role in tunnel construction. In places where many large-scale equipment cannot handle, the combined excavator with excavator milling head can effectively cut the rock and soil in the tunnel, repair the inner wall of the tunnel, and ensure the subsequent tunnel construction. The urban excavation of urban tunnel rock formations is easily affected by road construction and mountain rock formations, and has high requirements for surface settlement. If traditional construction techniques such as blasting or breaking hammer are used, it is easy to cause excessive excavation, which will cause irreversible impacts on surface buildings or mountains.

The hydraulic rock excavator milling head is a hydraulic machine tool used in conjunction with an excavator, driven by an oil motor. Supporting facilities The excavator is given a hydraulic power system to drive the oil motor, and the motor drives the milling head to rotate according to the transmission device. The picks assembled on the milling head thus mill the contacted raw material. It is composed of picks, milling heads, sound card racks, transmissions, drive motors, connection mechanisms, etc. According to the layout of hydraulic rock soil excavator milling head excavator milling head, hydraulic rock soil excavator milling head can be divided into horizontal excavator milling head (also known as oil pressure cutting machine) and vertical excavator milling head (Also known as random cross-section excavators).

According to the principle of cutting and excavation, factors affecting the efficiency of cutting construction include the geological conditions of surrounding rock and equipment performance. The principle of cutting and crushing is to cut, grind and break the surrounding rock. The geological conditions of the surrounding rock mainly include three factors: the physical and mechanical properties of the rock, usually the strength and wear resistance of the rock; Relative relationship, that is, rock joints, interstitial intervals and distribution; geohydrological environment, interstitial water abundance, etc. rock strength. The process of cutting and destroying rock by cutting equipment is the process of rock from elasticity to plasticity to destruction, so the strength of rock is directly related to the crushing efficiency of the cutting machine.
