Chain Cutter for Excavating Rock/Soil and Its Application

Abstract

A chain cutter for excavating rock and/or soil has one or more chains and cutters fixed on the chains, such that the central line of the one or more chains can form a spatial curve. Adjacent returning cutters on the chain cutter non-excavating face are staggered in the lengthwise direction of the chains, and are in a mutually embedded arrangement in the widthwise direction, or adjacent returning cutters on the chain cutter non-excavating face are in a stacked arrangement in the lengthwise direction of the chains, i.e. the widths of the chain cutter excavating faces are greater than the widths of the non-excavating faces, such that a machine frame in an annular enclosed region of the chain cutter and a machine frame outside the enclosed region are connected together as one within the width range of the excavating faces.
