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.

  • Specific Method of Implementation
  • A chain blade for excavating rock/soil is composed of a chain and a cutter fixed to the chain, and the center line of chain is a space curve.
  • The chain blade described is a multi-row chain blade in a width direction when used. The cutters of adjacent returned chain blades used for a non-excavation surface are arranged in a staggered way in the length direction, and are arranged in an embedded way in width direction, that is, the width of a rock/soil surface excavated by the multi-row chain blade is larger than the width of the non-excavation surface, so that a frame of the chain blade within the annular enclosed area and a frame outside the enclosed area are connected as a whole within the width of the excavation surface.
  • The chain blade described is a multi-row chain blade in a width direction when used. The adjacent returned chain blades used for the non-excavation surface are arranged in an overlapping way, that is, the width of a rock/soil surface excavated by the multi-row chain blade is larger than the width of the non-excavation surface, so that a frame of the chain blade within an annular enclosed area and a frame outside the enclosed area are connected as a whole within the width of an excavation surface.
  • The same cutter of the chain blade described is integrally connected with chain links of multiple chains to enhance the strength and rigidity of the chain blade.
  • The chain blade described has different cutters arranged on the same chain to meet different requirements.

  • The present invention is further described below in combination with the attached drawings:
  • As shown in FIG. 1, the chain blade 1 used for excavating rock/soil includes a concave universal joint 1-1-1 and a convex universal joint 1-1-2. The rotation of concave and convex universal joints can enable chain blade 1 to rotate in the direction parallel to excavation surface, and the rotation between the chain 1-1 and the concave and convex universal joints can enable chain blade 1 to rotate in the direction perpendicular to excavation surface, thus the rotation of two perpendicular planes causes the center line of the traveling track for chain blade 1 to be a space curve;
  • As shown in FIG. 2-FIG. 5, the cutters 1-2 of adjacent returned chain blade 1 used for the non-excavation surface are arranged in a staggered way in the length direction of the chain 1-1, and the structure is arranged in an embedded way in the width direction, thus the width of non-excavation surface is less than that of frame 2A, so that the frame 2A-1 of the chain blade 1 within the annular enclosed area and the frame 2A-2 outside the enclosed area are connected as a whole within the width of the excavation surface.
  • As shown in FIG. 6-FIG. 9, the traveling track of the chain blades 1 used for the excavation surface of the frame 2A-1 within the annular enclosed area of the chain blade of the frame 2A is parallel, the width of the excavation surface is greater than or equal to that of the frame, and the traveling track of the chain blade 1 used for the non-excavation surface is large at both ends and narrowed in the middle, so the width of the non-excavation surface except for the two ends is smaller than that of the frame.
  • As shown in FIG. 10-FIG. 14, the adjacent returned chain blades 1 used for the non-excavation surface are arranged in an overlapping way, and a certain distance is left in the height direction between the adjacent returned chain blades 1, and the center line of the chain blades 1 track forms two closed loops as shown in FIG. 10; the two chain blades 1 used for the excavation surface are arranged in a parallel way, the excavation width is equal to the width of the frame 2B, as shown in FIG. 11; the traveling track of returned chain blades 1 is bent from the ends to the middle, and the middle of the track is arranged along the center line, as shown in FIG. 12 and FIG. 13, the overlapping arrangement of the returned chain blades 1 used for the non-excavation surface making the frame 2B-1 in the annular enclosed area of the chain blades and the frame 2B-2 outside the enclosed area connected as a whole within the width of the excavation surface, as shown in FIG. 14.
  • As shown in FIG. 15, the traveling track of the chain blade 1 is a semi-circular arc, and two chain blades 1 form a full circular structure.
  • As shown in FIG. 16, the chain blade 1A is a chain blade used for excavating rock/soil, which is formed by two chains 1A-1 on the same cutter 1A-2, the tensile load of the chain blade being increased and the adaptability being strong.
  • As shown in FIG. 17, the chain blade 1B is a chain blade with various different cutters (I-type cutter 1B-2 and II-type cutter 1B-3) on the same chain, different cutters are arranged in a line with spaces on the same link, the same kinds of cutters on the adjacent chain links are arranged in a longitudinal staggered way, the section of chain blade is shaped like a tooth, excavating rock/soil at multiple points and small areas, which can reduce the tensile load of the chain blade, and the various geological conditions being able to be adapted to by changing the cutters and the arrangement of the cutters.
