Shield machine dramatically increases the mobility of the cutting soil body, improves the stock-removing efficiency of shield machine, reduce cutter in progradation
Abrasion.Shield machine continues to push ahead, and goat's horn knife starts to cut the soil body, because the goat's horn knife of installation has certain difference in height,
Substantially increase stock-removing efficiency of the shield machine in sand soft rock stratum.Treat that fish tail knife, dual-pilot cutter, goat's horn knife fully enter skiver
After work, the hobboing cutter being arranged on cutter head panel starts to cut, and greatly reduces the degree of wear of hobboing cutter.
Preferably, adjacent the goat's horn knife and dual-pilot cutter is highly consistent.
By using above-mentioned technical proposal, goat's horn knife is highly consistent with dual-pilot cutter, prevents shield machine in the course of the work, knife
Tool occurs the situation of breaking because height fall is excessive.
Preferably, during the cutter head panel rotation, the dual-pilot cutter shear action of fish tail knife knife face side is in fish tail knife knife face
The region of the adjacent dual-pilot cutter of opposite side.
By using above-mentioned technical proposal, in rotary course, the dual-pilot cutter of fish tail knife side is carried out cutter head panel first
Cutting, when the dual-pilot cutter of fish tail knife opposite side is cut to same position, the dual-pilot cutter of the side can be cut before in advance just
The unhewn part of knife, greatly improves stock-removing efficiency.
Preferably, the center of the cutter head panel opens up fluted, and the groove is embedded in the knife tail of fish tail knife.
By using above-mentioned technical proposal, the knife tail of fish tail knife is embedded in cutter head panel, the phase of fish tail knife and cutter head panel
Junction product is only bolted compared to fish tail knife, the increase of its connection area, has effectively been disperseed fish tail knife and has been acted only on bolt
On active force.
Preferably, the groove is T-slot, and the knife tail of the fish tail knife is T-shaped.
It is T-shaped cooperation by using above-mentioned technical proposal, between fish tail knife and groove, its active force is scattered more uniform.
Preferably, the outer layer welding of the goat's horn knife is provided with alloy-layer.
By using above-mentioned technical proposal, the alloy-layer of goat's horn knife outer layer, goat's horn knife is effectively reduced on sand soft rock stratum
In the rate of wear.
In summary, the utility model has the advantages that：For shield machine when cutting the sand soft rock soil body, fish tail knife is first
The sand soft rock soil body is first cut, for shield machine during driving, the dual-pilot cutter for being arranged at fish tail knife both sides then cuts the soil body, shield
Structure machine dramatically increases the mobility of the cutting soil body, improves the stock-removing efficiency of shield machine, reduce cutter in progradation
Abrasion.Shield machine continues to push ahead, and goat's horn knife starts to cut the soil body, substantially increases shield machine cutting in sand soft rock stratum
Cut efficiency.After fish tail knife, dual-pilot cutter, goat's horn knife fully enter cutwork, the hobboing cutter being arranged on cutter head panel starts to cut
Cut, greatly reduce the degree of wear of hobboing cutter.Meanwhile the alloy-layer for being arranged at goat's horn knife outer layer also substantially increases the resistance to of cutter
The degree of wear.
