The major diameter slurry balance push-bench cutterhead of described applicable gumbo construction, is characterized in that: the outer wall of described cutterhead is provided with several the 5th knife rests distributing along annular space.
The utility model has the advantages that:
The utility model structure design is novel, and the distribution on cutterhead by cutter setting frame and mud discharging mouth, has carried out rational layout, makes cutterhead can be applicable to the complicated soil layers such as gumbo, and practical application effect is good, has greatly improved jacking efficiency.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
Referring to accompanying drawing:
The major diameter slurry balance push-bench cutterhead that is applicable to gumbo construction, comprise disk body 1, the center of disk body 1 is provided with the spindle mounting hole 2 of slurry-water balance type push-bench, spindle mounting hole 2 peripheries are distributed with three row the first knife rests 3, three row the second knife rests 4 radially, every row the first knife rest 3, every row the second knife rest 4 form by the knife rest distributing along cutterhead spaced radial, angle in three row the first knife rests 3, three row the second knife rests 4 between adjacent column knife rest center line equates, between two adjacent row the first knife rests 3, is provided with row second knife rest 4; The cutterhead 1 of every row the first knife rest 3 both sides is provided with a row mud inlet A5, the cutterhead of every row the second knife rest 4 both sides is provided with a row mud inlet B6, and every row mud inlet B6 consists of the rectangular opening of the consistent size in the rectangular opening radially-arranged, size increases gradually and outside.
Every row the first knife rest 3 both sides are respectively equipped with one and are listed as three-tool post 7, and every three-tool post 7 both sides that are listed as are provided with a row mud inlet C8; Every row knife rest 7 both sides are respectively equipped with one and are listed as four blade frame 9, and every four blade frame 9 both sides that are listed as are provided with a row mud inlet D10.
