Abstract
The utility model discloses an asymmetric suction port device for a cutter suction dredger, which comprises a reamer body, a reamer shaft, a suction port and a grille, wherein the reamer body is assembled on the reamer shaft, the assembled reamer body is provided with the suction port, while a grille is arranged in the suction port, and the outer surface of the reamer body is provided with an annular reamer outer ring; the area ratio of a suction port area of the suction port to an overall area of the reamer body is different according to the excavated soil properties, and the shape of the suction port is matched with that of the reamer body, while the central position of the suction port deviates from the vertical central line of the reamer shaft along the rotating direction of the reamer shaft, so that a deviation angle exists between the vertical central line of the reamer shaft and the central position of the suction port. Due to the adoption of the scheme, the relative area of the suction port is increased, the slurry suction quantity of the cutter suction dredger is greatly increased at each time, the maximization of the suction quantity is realized, and the construction operation efficiency and the operational capability of the single ship are improved.
Description
Technical field
The utility model relates to the technical field of boats and ships, refers in particular to a kind of asymmetric sucking hole device that is used for cutter suction dredger.
Background technology
Cutter suction dredger is widely used in the improvement and the harbour of inland river, seaway and safeguards.Reamer is the tool of production of the indispensability of cutter suction dredger.Improve the suction inlet of reamer device, the projector who improves concentration of hydraulic mixture and be always cutter suction dredger pursues, and the good suction inlet that is complementary with reamer can significantly improve concentration of hydraulic mixture, thereby enhances productivity, and receives the effect of getting twice the result with half the effort.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of simple in structure, asymmetric sucking hole device that is used for cutter suction dredger that can improve the work capacity of cutter suction dredger construction operation efficient and boats and ships list ship greatly is provided.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of asymmetric sucking hole device that is used for cutter suction dredger, and it includes cutter hub, mangler shaft, suction inlet, grid, wherein; Described cutter hub is assemblied on the mangler shaft; Cutter hub after the assembling is provided with suction inlet, in this suction inlet a grid is housed simultaneously, and is provided with the reamer outer ring of annular at the cutter hub external surface; The area ratio of the area in the suction inlet zone of said suction inlet and the overall region of cutter hub is different with excavating soil property; And its shape and cutter hub are complementary; Simultaneously the vertical center line of mangler shaft is departed from along the direction of rotation of mangler shaft in the center of suction inlet, makes to have deflection angle between the center of vertical center line and suction inlet of mangler shaft.
The size of described deflection angle is different because of the maximum cut of mangler shaft rotating speed and suction inlet correspondence, and maximum is no more than 15 °.
The shape of said grid is consistent with the shape of suction inlet inner chamber.
The utility model is after having adopted such scheme; Its great advantage is to increase greatly the once suction slurry amount of cutter suction dredger; Realize the maximization of soakage; Improve the work capacity of its construction operation efficient and boats and ships list ship, concentration of hydraulic mixture can improve 30% under all constant situation of miscellaneous equipment, and the grid at suction inlet place can prevent that non-essential foreign material from getting into the mud quality after causing the suction inlet fault or have influence on absorption in the suction inlet simultaneously.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1; The described asymmetric sucking hole device that is used for cutter suction dredger of present embodiment includes cutter hub 1, mangler shaft 2, suction inlet 3, grid 4; Wherein, described cutter hub 1 is assemblied on the mangler shaft 2, and this cutter hub 1 external surface is provided with the reamer outer ring 5 of annular simultaneously; Cutter hub 1 after the assembling is provided with suction inlet 3, and the suction inlet of this suction inlet 3 zone is different with excavating soil property with the ratio of the overall region of cutter hub 1, and its shape and cutter hub 1 are complementary.Because when in real work, adopting traditional symmetrical expression suction inlet to carry out operation, the cutting point of cutter hub 1 tends to depart from the center of suction inlet 3, can make that so the once suction slurry amount of whole cutter suction dredger is little, and then reduce its operating efficiency.So from above situation; The vertical center line of mangler shaft 2 is departed from the center of the described suction inlet 3 of present embodiment along mangler shaft 2 direction of rotation; Make and have deflection angle between the center of vertical center line and suction inlet 3 of mangler shaft 2; The size of angle is different because of the maximum cut of mangler shaft 2 rotating speeds and suction inlet 3 correspondences, and maximum is no more than 15 °.After the utility model adopts asymmetric suction inlet 3; Can increase the once suction slurry amount of cutter suction dredger greatly; Realize the maximization of soakage, improve the work capacity of its construction operation efficient and boats and ships list ship, concentration of hydraulic mixture can improve 30% under all constant situation of miscellaneous equipment; Owing to the utility model one grid 4 is housed in suction inlet 3 simultaneously, and the shape of grid 4 is consistent with the shape of suction inlet 3 inner chambers.The utility model can prevent that non-essential foreign material from getting into the mud quality after causing suction inlet 3 faults or have influence on absorption in the suction inlet 3 through grid 4 like this, and security reliability is high, is worthy to be popularized.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
