Description
Technical field
The invention belongs to Dredging Technology field, more particularly to a kind of dredging drag head two-sided vomerine tooth of band bath.
Background technology
At present, free floating suction dredge(r) is dug in the engineering of closely knit class soil property dredging, due to closely knit class soil property compactness is high,
Grain composition preferably etc. properties, many difficulty and trouble are brought to Dredging Process.Due to pointed tooth, the structure limitation of flat tooth makes
It breaks ground after burying and scarce capacity or cannot effectively bury;Even if being applicable in vomerine tooth to excavate it, similarly cannot effectively bury
Or resistance is excessive after burying, it is impossible to which realization is continuously broken ground.Therefore in the engineering construction of closely knit class soil property, time-consuming and laborious, labor
Fatigue resistance is big, low production efficiency, of high cost, exists and spends the technical problems such as more human and material resources and financial resources.
Invention content
The present invention provides a kind of dredging drag head band bath twin wrest to solve technical problem present in known technology
Tooth.
The object of the present invention is to provide one kind have it is simple in structure, it is easy to assembly, increase the perturbed force to closely knit class soil property,
Energy continuous effective completes action of burying, loosen the soil, break ground and dig, and improves the efficiency for excavating closely knit class soil property, reduces the labor of crewman
Fatigue resistance reduces the construction period, and dredging drag head the features such as suitable for excavating closely knit class soil property uses band to wash by water two-sided vomerine tooth.
The present invention is composed of toothholder and tooth, and the dredging drag head two-sided vomerine tooth of band bath is made of, toothholder toothholder and tooth

The vomerine tooth is composite structure, is made of toothholder and tooth, toothholder is welded at drag head wear-resistant block position, and tooth is with the side of insertion
Formula install, tooth top is installed into sealing rubber ring, along toothholder fluting at be inserted into, you can use.Mounted vomerine tooth it is noted that the tooth wing with
The angle in direction is navigated by water, this angle can be controlled at 15~45 ° or so.Two-sided vomerine tooth is washed away with water function is blown using high pressure
Ability soil is loosened, be aided with the cooperation of the appropriate speed of a ship or plane, effect is more preferable.Two tooth wings simultaneously, after vomerine tooth buries, profit
It is effectively broken ground with the tooth wing so that closely knit class soil property is cut, and cutting output is big in advance before drag head is reached, conducive to rake below
Tooth excavates and the suction of dredge pump.Under certain ship's speed, operation of digging is carried out, earth of being digged can backward be transported along tooth wing upper surface
It is dynamic, hold-up of the earth in suction inlet forepart of being digged can be greatly reduced so that work of digging is more effective.
The present embodiment vomerine tooth is installed at the wear-resistant block position of drag head, can efficiently use the weight of drag head so that vomerine tooth is easy
In burying;The machine cut ability for the sluicing ability and vomerine tooth for blowing water function can be utilized simultaneously, hence it is evident that strengthen drag head
It breaks ground ability;It only needs to dismount after rake teeth abrasion, replace denticle, without welding, more efficient without special fixation, cost is lower,
It is convenient and time-saving.The present embodiment, which has, makes closely knit class soil property be cut in advance before being excavated by rake teeth, plays what is loosened the soil and dig
Effect effectively increases break ground ability and the amount of breaking ground of rake teeth, improves construction production efficiency, reduce the duration, suitable for digging
Dig the good effects such as the ship dredging constructions such as closely knit class soil property.
