Abstract
The utility model discloses a dredging reamer which includes a base and a plurality of reamer arms, wherein one end of every reamer arm is fixed on the base and the other ends of reamer arms are fixed together to form a shape of a cage. A net guarding against stones which is located on the inner side of every reamer arm is also arranged on the base. The net guarding against stones is located on the inner side of every reamer arm to prevent bigger stones from entering an absorption device through gas between reamer arms and avoid damage to the absorption device.
Description
Technical field
The utility model relates to dredge boat, is specifically related to the reamer of dredging.
Background technology
It is dredged channel and the capital equipment of reclaiming land from the sea in constructing that strand is inhaled ship, and its basic functional principle is the certain vacuum of effect generation by centrifugal dredge pump on ship, pumps after the mud that excavates is sucked, then discharges by the dredging tube line on ship.The concrete practice is, the bridge of bow front end is put into below the water surface, by crane span structure dredge foremost reamer rotation under water silt dig pine, and by slush pump produce negative-pressure sucking silt from releasing under water, then be blown into the zone of appointment.
Strand is inhaled in the ship work progress often can run into the zone that stone is arranged, and therefore stone may occur dredged and destroy the phenomenon of inhalation device after reamer sucks, thereby affect dredging operation.
The utility model content
Technical problem to be solved in the utility model is that the existing reamer of dredging of solution can't prevent the problem than the ratchel suction.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of reamer of dredging, comprise base and a plurality of reamer tool arm, described reamer tool arm one end is fixed on described base, the other end is fixed together and surrounds the cage shape, also be fixed with anti-stone net on described base, described anti-stone net is positioned at the inboard of described reamer tool arm.
In the above-mentioned reamer of dredging, described anti-stone net forms round table-like by the reinforcing bar welding.
In the above-mentioned reamer of dredging, described base is circular.
In the above-mentioned reamer of dredging, described reamer tool arm bends to helical form.
The reamer of dredging that the utility model provides is provided with anti-stone net in the inboard of reamer tool arm, can prevent that larger stone from entering inhalation device by the gap of reamer tool arm, thereby avoid damaging inhalation device.
Description of drawings
The structural representation of the reamer of dredging that Fig. 1 provides for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made detailed explanation.
As shown in Figure 1, the reamer of dredging that the utility model provides comprises base 1 and a plurality of reamer tool arm 2, and in present embodiment, reamer tool arm 2 is five.Base 1 is circular, and reamer tool arm 2 bends to helical form, and reamer tool arm 2 one ends are fixed on base 1, and the other end is fixed together and surrounds the cage shape.
Also be fixed with anti-stone net 3 on base 1, anti-stone net 3 is positioned at the inboard of reamer tool arm 2, and anti-stone net 3 forms round table-like by the reinforcing bar welding.
The reamer of dredging that the utility model provides is provided with anti-stone net 3 in the inboard of reamer tool arm 2, can prevent that larger stone from entering inhalation device by the gap of reamer tool arm 2, thereby avoid damaging inhalation device.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
