Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figures 1 to 4, the cutter head of shield machine structure of the present embodiment, described shield machine comprises main body 1, and described cutterhead 2 is arranged on main body 1 front end, cutterhead 2 for underground excavation soil stone.Drill bit 3 is provided with in the middle part of described cutterhead 2.Described cutterhead 2 is provided with multiple support portion 21, multiplely scrapes broken portion 22 and multiple collection unit 23, and described support portion 21 is extended to form to cutterhead 2 edge by drill bit 3.Support portion 21 is provided with pinch roller 4, described in scrape broken portion 22 and be arranged between adjacent supports portion 21, scrape edge, broken portion 22 and be provided with scraper part 5.Described collection unit 23 is arranged on scrapes between broken portion 22 and support portion 21, and collection unit 23 is depressed in cutterhead 2 surface, and namely collection unit 23 and support portion 21 exist difference in height.Described collection unit 23 is provided with arrival end 231 on cutterhead 2 edge.In technique scheme, hole can be offered on rock mass 6 by drill bit 3, by pinch roller 4 by pressure break around hole, ground be scraped broken by scraper part 5, and rubble is scraped into collection unit 23.
As shown in Figures 1 to 4, further, described support portion 21 is provided with multiple accommodation section 211, and described pinch roller 4 is arranged in accommodation section 211.Describedly scrape broken portion 22 and comprise connecting portion 201 and auxiliary section 202, there is between described adjacent supports portion 21 handing-over end 212, described connecting portion 201 connects auxiliary section 202 and handing-over end 212 respectively, thus makes collection unit 23 both sides be respectively equipped with scraper part 5 and pinch roller 4, is conducive to pulverizing ground.Described auxiliary section 202 is fan-shaped, and auxiliary section 202 comprises two side end faces 203, and described side end face 203 is provided with scraper part 5, described connecting portion 201 both sides are provided with scraper part 5, thus make scraper part 5 be arranged in " Y " type, thus the point of application is excavated in dispersion, is conducive to improving digging efficiency.Described drill bit 3 is convexly equipped in cutterhead 2 surface, and drill bit 3 is triangle, thus is conducive to the excavation of drill bit 3.Described pinch roller 4 is cylindric and surface is provided with lug boss 41.Be provided with pivot in described pinch roller 4, pinch roller 4 can pivot.Described scraper part 5 comprises connector 51 and cutter hub 52, cutter hub 52 comprises the first cutter hub 521 and the second cutter hub 522, first, second cutter hub 521,522 is inclination 45 degree setting, by two cutter hubs, when the first cutter hub 521 maybe cannot use because wearing and tearing depart from, second cutter hub 522 can replace its operation, carries out replacing cutter hub without the need to stopping operation.Described first cutter hub 521 side is provided with mating part 53, and described mating part 53 is provided with side tool body 54.The tip 541 of described side tool body 54 exceeds cutterhead 2 edge, thus can strike off the rock mass 6 beyond cutterhead 2, and brings rubble into collection unit 23 by arrival end 231, avoids cutterhead 2 periphery to be squeezed.Described connector 51 is provided with multiple perforation 511,511 scraper part can be fixed on cutterhead 2 by boring a hole.
