The patent application (Publication Number: US20240026640A1) describes an excavation machine with a unique cutting head design. The machine includes a vertical frame with a cutting head at the lower end, consisting of two drums positioned side by side. Each drum has a cutting disc or mounting means at its distal end, with the discs having a diameter equal to or greater than that of the drums. The cutting discs are positioned in the same plane, enhancing cutting efficiency. The drums also feature mounting means with bearing surfaces and fasteners for attaching the cutting discs securely.

Furthermore, the excavation machine can include additional cutting discs on separate drums, all positioned in the same plane. The cutting discs may have cutting materials like tungsten carbide or diamond powder on their rims for enhanced cutting performance. The patent also covers a method for cutting metal elements using the excavation machine, involving rotating the drums in opposite directions and translating the cutting head downward. The method includes attaching cutting discs to the drums after removing teeth, ensuring precise cutting in the same plane with the help of bearing surfaces and tapped holes. Overall, the patent highlights a novel excavation machine design with improved cutting efficiency and precision, offering potential benefits in various excavation applications.
