Description

The cutting member that is used for dredging system
Technical field
The present invention relates to a kind of cutting member that dredging system for example is used for drag head that is used for, it comprises tooth, toothholder and is used near the pipeline that current are provided the edge of a knife that described tooth is provided with a cavity, and described toothholder is provided with one makes it fit snugly in the interior tip of cavity.
Background technology
Such cutting member is known.When dredging system for example drag head when water bottom moves, dig out base material by such cutting member.The base material of digging out is collected in the main body under suitably directed water jet influence, and is sent in the funnel such as a container by a suction tube.
In addition, the water jet of incorporating cutting member into helps cutting operation.Under certain pressure, water is sent in the pipeline in the cutting member, and this pressure should be bigger than the pressure of ambient water.These water jets also stop things such as dirty Hou to invade in the pipeline.
The intensity of cutting process is depended in the wearing and tearing that cutting teeth is subjected to.After the certain hour, must replace cutting teeth with new tooth.The tooth of grinding away has to take apart from toothholder.Equally, the pipeline on the cutting member also must be opened.In fact, obviously the connection and the unpack procedure of pipeline will bring variety of issue, and be undesired as the sealing between pipeline, toothholder and the tooth, this means that thing such as dirty Hou can enter join domain.This is extremely undesirable thing, may be damaged because connect the surface.
Summary of the invention
The purpose of this invention is to provide a kind of above-mentioned cutting member that can address these problems.This purpose realizes like this: toothholder has toothholder passage, a tooth that a tooth passage is arranged, and an end and the toothholder passage of a feed pipe join, and the other end and tooth passage join.
In cutting member of the present invention, the flow path of water is determined by the feed pipe that not only extends in the toothholder but also extend in the tooth.Therefore, need on toothholder and tooth facing surfaces, not seal.Thus, the connection of tooth and toothholder and unpack procedure can be more simple.And can obtain better sealing.
At this on the one hand, can be by sealing system with feed pipe and toothholder channel seal.In addition, by pilot sleeve, can make the relative tooth passage of feed pipe orientation.
In addition, toothholder can have a joint face that is connected to storage chamber, one to open and be connected to cavity on the toothholder passage at described joint face place, and described storage chamber has the feed water inlet that the cavity place on the toothholder passage opens.
The invention still further relates to a drag head that is used for dredging system, it comprises: the one end is useful on the main body of the linkage that connects a suction tube; One is hinged on shield relative with linkage on the main body; Be located at the interior at least one row of shield according to aforementioned cutting member of the present invention, each cutting member all comprises a tooth and toothholder, and described toothholder has a tip, and described tooth has a cavity, tip and cavity closely cooperate, and each cutting member all comprises one near the pipeline that current are provided the edge of a knife; And the water supply installation that is connected with this pipeline.
According to the present invention, toothholder has a toothholder passage, and tooth has a tooth passage, and an end of a feed pipe is inserted in the toothholder passage, and the other end is inserted in the tooth passage.
Describe the present invention below with reference to the cutting member that is combined in as shown in drawings in the drag head.
Description of drawings
Fig. 1 is the phantom drawing of drag head.
Fig. 2 is the front elevation drawing of drag head.
Fig. 3 is the lateral view of drag head.
Fig. 4 is the sectional view of the IV-IV of Fig. 2.
Fig. 5 incorporates the amplification view of the tooth of drag head along the V-V of Fig. 2 into.
Fig. 6 is the sectional view of the drag head of working similar to Fig. 4 sectional view.
The specific embodiment
Drag head shown in Fig. 1-3 comprises main body 1, and the one end is equipped with mounting flange 2.By mounting flange 2, this drag head can excavate the container (not shown) with a suction tube and and couple together.The other end of main body 1 part 4 that is connected through the hinge is carrying a so-called shield 3.The incline direction of shield 3 relative bodies 1 can be regulated by hydraulic piston/cylinder assembly 5.
Shield 3 is carrying two row's cutting members 6,7 of being made up of cutting member 8, and each cutting member 8 all has a nozzle 36 (other row numbers also can).These cutting members are exaggerated and are shown among Fig. 5.Each cutting member 8 comprises a cutting teeth 9 and a toothholder 10.Toothholder 10 has an installing component 11, and installing component 11 is connected to toothholder on the cross bar 12 on every row 6,7.In addition, each tooth 9 all has a cavity 14, and the tip 13 of installing component 11 fits snugly in the cavity 14.By inserting the pin (not shown) of toothholder and tooth, can stop axial displacement.
Each toothholder 10 all has a toothholder passage 15, and the one end is opening wide cavity 16 of formation, and the other end is admitted a feed pipe 17.Feed pipe 17 closely is installed in the toothholder passage 15 by a sealing system 18.In addition, tooth 9 has a tooth passage 19, and this passage is the shape of slight curvature, and the respective curved of feed pipe 17 extends partially in this passage.At the free end of feed pipe 17, feed pipe 17 relative tooth passages 19 are led by pilot sleeve 20.
As shown in Figure 4, the toothholder cavity 16 of each toothholder 10 communicates with feed water inlet 21 in the cross bar 12.Each cross bar limits a storage chamber 22, and storage chamber 22 feed pipe 23,24 is separately supplied with its pressure (hydraulic) water.Each feed pipe 23,24 all is connected on the manifold 25, by feed pipe 26 pressure (hydraulic) water is supplied with manifold.
In addition, nozzle 28 is connected on the main body 1, and nozzle 28 communicates with feed pipe 26 by storage chamber 27 again.
Fig. 6 illustrates the general direction of drag head according to the present invention relative water bottom 29 during cutting operation.By hydraulic piston/cylinder assembly 5, the relative in the following manner main body orientation of shield 3 quilts: make the edge of a knife 30 of tooth directed a little downwards; And make the current of sending from cutting teeth 8 make progress directed a little.Extra current are sent by nozzle 28,31 and 32, enter in main body 1 and the suction tube to force the water bottom material that cuts away.
Though the front is illustrated drag head, can on various dredging systems, use according to cutting member of the present invention, such as dredging system of being with nicking head, scraper bowl or the like.
