Specific implementation mode
Figures 1 and 2 show that the application it is this can a concrete application example of the rubble reamer device on cutter suction dredger,
Cutter suction dredger includes hull, (into mud side, i.e., is inhaled in mudstone with the fixed crane span structure 8 of hull, mud suction mouth 4, on the outside of mud suction mouth
Enter the upstream side of mud suction mouth on direction) reamer and (mud is inhaled in spoil disposal side on mudstone sucking direction on the inside of the mud suction mouth
Mouthful downstream side) dredge pump.When work, the processing that extraneous mudstone first passes through reamer flows into mud suction mouth 4, then is inhaled from mud suction mouth 4
Enter in dredge pump.Wherein, reamer and mud suction mouth 4 constitute reamer device, which is arranged the leading portion in crane span structure 8.With it is traditional
Reamer device is identical to be, this reamer device of the present embodiment also includes mud suction mouth 4 and is located on the outside of mud suction mouth (into mud
Side) reamer, wherein mud suction mouth 4 is fixed on crane span structure 8, and reamer includes mangler shaft 1, reamer arm 2 and reamer circle 3.
The key improvements of the present embodiment are：Fixed setting is useful for stopping that bulky grain stone enters suction mud in mud suction mouth 4
Multiple (at least one) fixed blades 5 of mouth 4.It is fixedly installed and is matched with fixed blade 5, will be blocked on reamer circle 3
The rotating blade 6 that bulky grain stone outside mud suction mouth 4 is crushed.
Mounting distance between fixed blade 5 need to determine according to the spherical channel of dredge pump, typically slightly less than the spherical shape of dredge pump
Channel seriously affects inhalant effect if spacing is too small, reduces construction efficiency.
When practical application, the larger stone of build is stuck in mud suction mouth 4 by fixed blade 5, when rotating blade 6 follows reamer circle
3 quickly when rotating to herein, and generating larger impact force and shearing force, broken (rotating blade 6 and fixed blade 5 are opposite by stone
High-speed motion, and the two carries cutting edge), and fixed blade 5 also has the function of broken stone, smashes rear stone and enters
Ni Kou is washed to be inhaled into dredge pump.
In the present embodiment, the cutting edge of above-mentioned rotating blade 6 is directed parallel to reamer circle 3 (plane at place), fixed blade 5
Cutting edge towards perpendicular to reamer circle 3 (plane at place).And rotating blade 6 is the plane blade for being parallel to reamer circle 3.
With reference to shown in Fig. 3 and Fig. 4, above-mentioned rotating blade 6 is fixed on reamer circle 3 by two pieces of fixed otic placodes 7, tool
Body：Multiple countersunk screw holes are offered on rotating blade 6 and fixed otic placode 7, rotating blade 6 and fixed otic placode 7 are by locking
Sunk screw in the countersunk screw holes is fixedly connected, and reamer circle 3 and fixed otic placode 7 are welded and fixed, and is so convenient for rotating knife
The installation and removal of piece 6 are exchanged.The length both ends of rotating blade 6 are arc-shaped structure, and the both ends of rotating blade 6 and reamer
Circle 3 inside rim flush arrangement --- the radius of aforementioned arc-shaped structure is consistent with the internal diameter of reamer circle 3.
With reference to shown in Fig. 3, Fig. 6 and Fig. 7, above-mentioned two pieces fixed otic placodes 7 are separately positioned on the length both ends of rotating blade 6.
One of fixed otic placode 7 is trapezoidal slab construction, opens up that there are four countersunk screw holes thereon.Another fixes 7 rectangle of otic placode
Slab construction is opened up thereon there are two countersunk screw holes.
With reference to shown in Fig. 2 and Fig. 5, above-mentioned each fixed blade 5 is fixedly welded in mud suction mouth 4.Fixed blade 5 includes square
The cutter hub of shape structure and the blade of wedge structure, wherein cutter hub is fixedly welded in mud suction mouth 4, and blade is located at outside mud suction mouth 4
Preferably to coordinate with rotating blade 6.In this way, can either ensure the stability of 5 installation site of fixed blade, and make fixing cutter
Piece 5 can preferably coordinate with rotating blade 6, with efficiency crushing bulky grain stone.
Certainly, above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to make people much of that
Solution present context is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application major technique
The equivalent transformation or modification that the Spirit Essence of scheme is done, should all cover within the protection domain of the application.
