Detailed Description
The present invention will be further described with reference to the following embodiments and accompanying drawings.
As shown in fig. 1-2, a crushing device of a stone crusher in a slurry balance shield machine comprises driving shafts 1 respectively arranged on the left side and the right side, wherein a plurality of crushing cutters 2 and shifting cutters 3 are sequentially and alternately arranged on the driving shafts 1 on the left side and the right side. A plurality of tooth-shaped cutters 21 are arranged on each crushing cutter 2 at equal intervals; a plurality of arc-shaped cutters 31 are arranged on each poking cutter 3 at equal intervals. The toothed cutters 21 on the same drive shaft 1 are in the same angular position. The arc-shaped cutters 31 on the same driving shaft 1 are in the same angle position. The angular positions of the toothed cutters 21 and the arc-shaped cutters 31 on the same driving shaft 1 are staggered. The crushing knife 2 on the left driving shaft 1 corresponds to the knife shifting 3 on the right driving shaft 1 in position, and the knife shifting 3 on the left driving shaft 1 corresponds to the crushing knife 2 on the right driving shaft 1 in position.
3 trapezoidal piece cutters 32 are welded on each shifting knife 3, the trapezoidal piece cutters 32 on each shifting knife 3 are arranged at equal intervals, the trapezoidal piece cutters 32 on the same driving shaft 1 are located at the same angle position, and the angle positions between the trapezoidal piece cutters 32 on the driving shafts 1 on the left side and the right side are staggered. The trapezoidal block cutter 32 comprises a base 321 and an extrusion block 322 arranged on the base 321, wherein the extrusion block 322 is in a trapezoidal structure.
