Description
Technical field
The present invention relates to strand and inhale shipborne equipment technical field, refer to especially a kind of being arranged on strand suction ship for digging the strand suction device of sand, sand discharge.
Background technology
It is a kind of for Dredger Filling Engineering that strand is inhaled ship, is suitable for excavating the working ship of the more loose river bed of soil property such as sandy soil, mud, is used for the construction in inland river, lake region and coastal port area, is topmost a kind of in existing dredge boat.The stern of this dredge boat has two guide piles, and while dredging, wherein an insertion river bed, as guide pile, pulls dredge boat with anchor hawser, centered by guide pile, swing and dredge, during reach, picture two legs are walked, and with another root steel column, alternately change stake, and the reamer process of dredging is fan-shaped and advances.The operation process of this cutter suction dredger can complete work one-time continuous such as dredging, transport mud, dump, is the dredge boat that a kind of efficiency is high, cost is low.
When the strand suction boatman of prior art does, need first the silt that is deposited on river bed, lakebed is stirred, then utilize slush pump that these muddy solidliquid mixtures are extracted out, then the silt wherein mixing is filtered out to the position that is discharged into appointment.But at present too complicated for stirring the apparatus structure of silt, greatly increased the cost of manufacture that strand is inhaled ship, and, in river bed, lakebed precipitating toward contact the solid that many volumes are larger, such as stone etc., in strand, inhales boatman while doing, the solid that these volumes are larger also can be stirred, and tend to be accompanied by silt and be inhaled into and inhale in sand tube, the equipment at cabin rear portion (such as slush pump etc.) is caused to damage, the normal work that impact strand is inhaled ship.
Summary of the invention
The present invention proposes a kind of strand and inhales device, has solved the problem of strand suction apparatus structure complexity in prior art.
Technical scheme of the present invention is achieved in that strand suction device, comprising:
Hydraulic motor, is connected with the power output shaft by its driving, and described power output shaft tilts to extend to front lower place;
Reamer head, is arranged on described power output shaft, by described power output shaft, drives its rotation, is provided with some reamer teeth on described reamer head;
Inhale sand tube, its import is positioned at the back lower place of described reamer head, and its port of export is connected with slush pump entrance point.
As preferred embodiment a kind of, described reamer head comprises:
Internal fixation disc, is fixed on the centre position of described power output shaft, and described internal fixation disc plane of living in is vertical with described power output shaft;
Outer retainer plate, is positioned at same plane coaxial setting with described internal fixation disc, and described outer retainer plate is located on the periphery of described internal fixation disc, is symmetrically fixed with to synchronize reinforcing rib between described outer retainer plate and described internal fixation disc;
Reamer arm, its quantity is many and circumferentially uniform along described outer retainer plate, one end of described reamer arm is fixed on the side surface of described outer retainer plate under oblique, oliquely downward round and smooth extension be fixed on the end of described power output shaft of the other end, is all fixed with a plurality of described reamer teeth on the reamer arm described in each.
As another preferred embodiment, the reamer tooth described in each includes base portion and tooth portion, and described base portion is fixed on corresponding reamer arm, hinged between described tooth portion and corresponding base portion, and all tooth portions are clockwise or counterclockwise and arrange.
As another preferred embodiment, between described tooth portion and corresponding base portion, all by jointed shaft, realize hingedly, on described jointed shaft, be all penetrated with spacer pin.
As the improvement to technique scheme, the import department of described suction sand tube is provided with sieves.
Adopted after technique scheme, the invention has the beneficial effects as follows: this strand is inhaled device and utilized hydraulic motor to drive power output shaft to rotate, then by power output shaft, drive reamer head to rotate, utilize the some reamer teeth on reamer head to stir being deposited in water-bed silt, last under the effect of slush pump, these muddy solidliquid mixtures are inhaled into inhales sand tube discharge, and it is simple that the strand of this structure is inhaled apparatus structure, operate more convenient, greatly reduced the cost of manufacture that strand is inhaled ship.
Stability when reamer head takes internal fixation disc and the synchronous frame mode rotating of outer retainer plate can increase the rotation of reamer head, contact area when many reamer arms that upwards arrange in retainer plate week outside can increase the rotation of reamer head and between precipitation silt, improves the operating efficiency that whole strand is inhaled device.
Reamer tooth is set to the hinged frame mode of base portion and tooth portion, to be the most serious position of taking up wear because twist reamer tooth while inhaling device work, be set to this split type structure and can after the wearing and tearing of tooth portion, only change tooth portion, reduce the maintenance cost that strand is inhaled device.
In the import department of inhaling sand tube, solid (for example stone) that sieves can be larger by the volume stirring is set and is blocked in and inhales outside sand tube, to avoid it to enter, inhale the equipment such as slush pump that damage cabin rear portion in sand tube.
