如图1所示，挖掘岩土的链刀1，包括凹型十字节1-1-1和凸型十字节1-1-2，凹型与凸型十字节的转动可使链刀1在平行挖掘面方向的转动，链条1-1与凹、凸型十字节之间的转动可使链刀1在垂直挖掘面方向的转动，这样两个垂直面上的转动使链刀1行走轨迹的中心线是空间曲线；As shown in Fig. 1, the chain cutter 1 for excavating the earth and soil includes a concave ten-byte 1-1-1 and a convex ten-byte 1-1-2, and the concave and convex ten-byte rotation can make the chain cutter 1 In the direction of the parallel excavation surface, the rotation between the chain 1-1 and the concave and convex ten-bytes can cause the chain cutter 1 to rotate in the direction of the vertical excavation surface, so that the rotation of the two vertical planes causes the chain cutter 1 to walk. The centerline of the trajectory is the spatial curve;
如图2～图5所示，非挖掘面的相邻返回链刀1的刀具1-2在链条1-1长度方向是错位布置，宽度方向互相嵌入布置的结构，所以非挖掘面的宽度小于机架2A的宽度，这样链刀1环形封闭区域内的机架2A-1才可以跟封闭区域外的机架2A-2在挖掘面的宽度范围内连接成一体。As shown in FIGS. 2 to 5, the cutters 1-2 of the adjacent return chain cutters 1 of the non-excavation surface are arranged in a misaligned manner in the longitudinal direction of the chain 1-1, and the width direction is embedded in each other, so that the width of the non-excavation surface is smaller than The width of the frame 2A is such that the frame 2A-1 in the annular closed area of the chain cutter 1 can be integrated with the frame 2A-2 outside the closed area within the width of the excavation face.
如图6～图9所示，机架2A在链刀环形封闭区域内的机架2A-1的挖掘面链刀1的行走轨道是平行的，挖掘面宽度大于或等于机架宽度，非挖掘面链刀1的行走轨道是两端大，中间向内收拢的，所以除两端外的非挖掘面的宽度小于机架的宽度。As shown in FIG. 6 to FIG. 9, the traveling track of the chain cutter 1 of the frame 2A in the annular closed area of the chain cutter is parallel, and the width of the excavation surface is greater than or equal to the width of the frame, and non-excavation The walking track of the face chain cutter 1 is large at both ends and is gathered inward in the middle, so the width of the non-excavation face except the ends is smaller than the width of the frame.
如图10～图14所示，非挖掘面的相邻返回链刀1重叠布置，在相邻返回链刀1之间高度方向留置一定距离，链刀1轨迹中心线形成两个闭环如图10所示；挖掘面两条链刀1并排布置，挖掘宽度等于机架2B的宽度如图11所示；返回链刀1行走轨道是在端部向中间弯曲，轨道中部是沿中心线布置的如图12、图13所示，非挖掘面的返回链刀1重叠布置使链刀环形封闭区域内的机架2B-1与封闭区域外的机架2B-2在挖掘面的宽度范围内连接成一体如图14所示。As shown in FIG. 10 to FIG. 14 , the adjacent return chain cutters 1 of the non-excavation surface are arranged in an overlapping manner, and a certain distance is left in the height direction between the adjacent return chain cutters 1, and the center line of the chain cutter 1 forms two closed loops as shown in FIG. 10 . As shown; the two chain cutters 1 of the excavation face are arranged side by side, the digging width is equal to the width of the frame 2B as shown in FIG. 11; the return chain knife 1 is to be bent in the middle at the end, and the middle of the track is arranged along the center line. 12 and 13, the non-excavation surface return chain cutters 1 are arranged in an overlapping manner such that the frame 2B-1 in the annular closed area of the chain cutter and the frame 2B-2 outside the closed area are connected within the width of the excavation surface. The integration is shown in Figure 14.
如图15所示，链刀1的行走轨道为半圆弧形，两条链刀1形成整圆结构。As shown in Fig. 15, the traveling rail of the chain cutter 1 has a semicircular arc shape, and the two chain cutters 1 form a full circular structure.
如图16所示，链刀1A是同一刀具1A-2上有两根链条1A-1的挖掘岩土的链刀，链刀的抗拉伸载荷增加，适应能力强。As shown in Fig. 16, the chain cutter 1A is a chain cutter for excavating rock having two chains 1A-1 on the same cutter 1A-2, and the tensile resistance of the chain cutter is increased, and the adaptability is strong.
如图17所示，链刀1B是同一链条上有多种不同刀具(Ⅰ型刀具1B-2和Ⅱ型刀具1B-3)的链刀，在同一链节上，不同刀具成一字型间隔布置，相邻链节上的同一种刀具纵向错开布置，链刀截面成齿形，多点小面积挖掘岩土，可减少链刀拉伸载荷，通过更换刀具和改变刀具的布置可适应各种不同地质情况。As shown in Fig. 17, the chain cutter 1B is a chain cutter having a plurality of different cutters (I-type cutter 1B-2 and type II cutter 1B-3) on the same chain, and different cutters are arranged in a line at the same link. The same tool on the adjacent links is arranged in a longitudinally staggered arrangement. The chain cutter has a tooth profile. The multi-point small area excavates the rock and soil, which can reduce the tensile load of the chain cutter. It can adapt to various changes by changing the tool and changing the arrangement of the tool. Geological condition.
