How does the Horizontal Drum Cutter Spear Parts Work?

The horizontal drum cutter spear parts are core components used for cutting soft rock or hard soil in underground engineering equipment. They are designed to achieve efficient stratum penetration through power drive. This component is usually composed of a main frame, a transmission device and a cutting disc. The main frame is responsible for connecting the external power source and transmitting torque, while the transmission device converts the power into the rotational motion of the cutter disc.

So how do horizontal drum cutter spear parts work?

Multiple groups of carbide tools are distributed on the surface of the cutter disc, which continuously cut the stratum through high-speed rotation. At the same time, the built-in slag discharge channel can timely remove the broken materials to ensure the cleanliness of the working surface.

The characteristics of the horizontal drum cutter spear parts are reflected in the structural adaptability and material durability. The overall modular design is adopted to facilitate the replacement of tool configuration according to different geological conditions. The main structure improves the impact resistance through the enhanced welding process. The cutter disc is treated with a composite heat treatment process to enhance the surface hardness while maintaining toughness, which can cope with the friction loss of different rock formations. The transmission system is equipped with multi-level sealing protection to effectively isolate the intrusion of external impurities and extend the service life of precision components.

During the operation, the power system drives the horizontal drum cutter spear parts to continuously advance, and the cutting force generated by the rotation of the cutter disc achieves crushing and stripping through the contact surface between the cutter and the formation. The cutting depth and feed speed are dynamically adjusted by the hydraulic system to ensure the balance between cutting efficiency and equipment load. The design of the horizontal drum cutter spear parts focuses on energy transfer efficiency, minimizes power loss as much as possible, and makes the mechanical energy more concentrated on the formation damage surface. Daily maintenance should focus on the wear status of the cutter and the lubrication of the transmission system, and replace the excessively worn units in time to maintain the overall operation efficiency.
