Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the utility model includes shield machine scraper 1, and protective shell 2, spring 4, connector 5, piston rod 6, circle
Guide rail 16 and limiter 8；Round guide 16, big end the 6th bolt 14 and the third of round guide 16 are housed on shield cutter 7
Bolt 11 is fixed on the lateral surface of 7 side of shield cutter, and the first bolt 1 of large end face of connector 5 and the second bolt 10 are fixed
Lateral surface in 7 other side of shield cutter, 6 small end cylinder of piston rod stretches out after passing through 16 centre bore of round guide outside connector 5, living
6 small end cylinder of stopper rod is to be slidably matched with 16 centre bore of round guide, and 6 big end cylinder of piston rod is stretched out in 7 side of shield cutter, living
6 big end cylinder exterior of stopper rod has limiter 8, the big end that limiter 8 passes through connector 5 with the 5th bolt 13 and the 4th bolt 12
Face is fixed on the lateral surface of 7 side of shield cutter, and 6 big end cylinder of piston rod is to be slidably matched with 8 hole of limiter, and piston rod 6 is big
End cylinder is provided with multiple axially extending bores, and the side centre bore of protective shell 2 is connect with 1 bottom tab of shield machine scraper, protective shell 2
Other side Large central aperture connect with the small end cylinder of connector 5, the other side Large central aperture of protective shell 2 is small with connector 5
End cylinder is to be slidably matched, and 6 small end cylinder of piston rod is connect with the small centre bore in the other side of protective shell 2, is stretched out outside connector 5
6 small end cylinder jacket of piston rod has a spring 4, one end and the 2 Large central aperture end in contact of protective shell of spring 4, the other end of spring 4 with
The lateral surface of 7 other side of shield cutter contacts.
Lubricating oil 15 is full of between 6 big end cylinder of the piston rod and limiter 8,6 big end cylinder of piston rod is provided with multiple axis
To through-hole, these axially extending bores allow lubricating oil 15 to circulate, in order to avoid the pressure in piston motion of lubricating oil 15 is excessive, cause to limit

Seven bolts 17 and the 8th bolt 18 are fixed in the small centre bore in the other side of protective shell 2.
The operation principle of the utility model：
As shown in Figure 1, when the compression of the spring 4 and elongation, the protective shell 2 being connected on spring 4 moves therewith, and connection is protected
Shield machine scraper 1 on protective case 2 is also elastic therewith, is scraped according to place strata condition adjust automatically shield machine to realize
The function of 1 working face of knife.
In soft soil layer, 4 stress of spring is smaller, and decrement is smaller.The working face of shield machine scraper 1 is in hobboing cutter at this time
（It is not drawn into, is mounted on shield cutter in figure）Before working face, i.e., shield machine scraper 1 contacts the soil body, shield prior to hobboing cutter
After machine scraper 1 shreds the soil body, avoids hobboing cutter and sink into the soil body and eccentric wear occurs.
In ground consisting of hard rock, 4 stress of spring is smaller, and decrement is larger.At this time shield machine scraper 1 in hobboing cutter be in same work
Make plane, since shield machine scraper 1 is connect by spring 4 with shield cutter 7, belongs to flexible connection, rigidity is less than hobboing cutter.Therefore
Attachment device reduces the frictional force that shield machine scraper 1 is subject to, to reduce the abrasion of shield machine scraper 1.
Above-mentioned specific implementation mode is used for illustrating the utility model, rather than limits the utility model,
In the spirit and scope of the claims of the utility model, to any modifications and changes that the utility model is made, all fall
Enter the scope of protection of the utility model.
