Abstract
The utility model discloses a dredging cutter for a cutter suction dredger. The dredging cutter comprises an annular base and a plurality of cutter arms fixed on the annular base; the outer circumferences of the cutter arms and the annular base are provided with a plurality of cutter teeth; and a stone preventing plate is arranged in a space enclosed by the plurality of cutter arms, is a steel ring and is fixed with inner surfaces of the cutter arms through a plurality of connectors. The stone preventing plate is arranged in the space enclosed by the plurality of cutter arms, so the stone preventing plate can prevent large block stones from entering suction equipment through gaps of the cutter arms and damaging the suction equipment.
Description
Technical field
The utility model relates to strand and inhales ship, is specifically related to strand and inhales the reamer of dredging peculiar to vessel.
Background technology
Strand suction ship is dredged channel and encloses the sea and make the capital equipment in the construction that its basic functional principle is the certain vacuum of effect generation through centrifugal dredge pump on the ship, sucks the mud that excavates gained, pump and pass through dredging tube line discharge on the ship again.The concrete practice is, the bridge of bow front end is put into below the water surface, through crane span structure foremost reamer rotation under water the mud face dig pine, and through negative-pressure sucking that slush pump produced silt from extracting out under water, and the appointed area that is blown into.
Strand is inhaled in the ship work progress and is run into piece stone branch than multizone through regular meeting, therefore, boulder possibly take place sucked back destruction inhalation device phenomenon by reamer, thereby influence the reamer dredging operation.
The utility model content
The utility model technical problem to be solved is to solve strand to inhale in the ship work progress, and boulder is sucked the problem that inhalation device is destroyed in the back by reamer.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted provides a kind of strand and inhales the reamer of dredging peculiar to vessel; Comprise annular base and be fixed on the said annular base and a plurality of reamer tool arms, be equipped with a plurality of reamer teeth on the outer circumferential surface of reamer tool arm and annular base, be provided with anti-slabstone in a plurality of reamer tool arm enclosed spaces; Said anti-slabstone is steel ring, and fixes with the inner surface of said reamer tool arm respectively through a plurality of connectors.
In such scheme, said connector is a steel pipe.
The utility model because in a plurality of reamer tool arm enclosed spaces, be provided with anti-slabstone, therefore, can stop bigger piece stone to get into inhalation device through the gap between the adjacent reamer arm, avoids stone piece stone to damage inhalation device.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the rear elevation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
Like Fig. 1, shown in Figure 2; The strand that the utility model provides is inhaled the reamer of dredging peculiar to vessel; Comprise annular base 1 and be fixed on the annular base 1 and a plurality of reamer tool arms 2; Be provided with anti-slabstone 3 in a plurality of reamer tool arm 2 enclosed spaces, anti-slabstone 3 is steel ring, and fixes with the inner surface of reamer tool arm 2 respectively through a plurality of connectors 4.Be equipped with a plurality of reamer teeth on the reamer tool arm 2 and on the outer circumferential surface of annular base 1, when annular base 1 rotated with reamer tool arm 2, inciting somebody to action under water through these reamers, the mud face dug pine.
When the utility model uses; Along with the rotation of annular base 1 and reamer tool arm 2, the reamer on annular base 1 and the reamer tool arm 2 mud face under water digs pine, and silt is under the effect of the negative-pressure sucking that slush pump produced; Gap between reamer tool arm 2 sucks; Owing in a plurality of reamer tool arm 2 enclosed spaces, be provided with anti-slabstone 3, therefore, can prevent that bigger stone from getting into from the gap between the reamer tool arm 2; Can not get into inhalation devices such as slush pump, thereby avoid inhalation device is caused damage through the intake that annular base 1 forms.The radius of anti-slabstone 3 can according to the specification of reamer head and with the set positions of intake.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.
Claims (2)
1. strand is inhaled the reamer of dredging peculiar to vessel; Comprise annular base and be fixed on the said annular base and a plurality of reamer tool arms; Be equipped with a plurality of reamer teeth on the outer circumferential surface of reamer tool arm and annular base, it is characterized in that, also comprise the anti-slabstone that is arranged on by in a plurality of reamer tool arm enclosed spaces; Said anti-slabstone is steel ring, and fixes with the inner surface of said reamer tool arm respectively through a plurality of connectors.
2. strand as claimed in claim 1 is inhaled the reamer of dredging peculiar to vessel, it is characterized in that said connector is a steel pipe.
