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.

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 the excavation
surface.
[0006] The chain blade is a multi-row chain blade in a width
direction when used. The adjacent returned chain blades used for a

Specific Method of Implementation
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] The chain blade described has different cutters arranged on
the same chain to meet different requirements.
[0031] The chain described includes a concave universal joint and a
convex universal joint.
[0032] The present invention is further described below in
combination with the attached drawings:
[0033] 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;
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
