Abstract
The invention discloses a reamer suction device used for a cutter suction dredger, which comprises a reamer body, a reamer shaft, a suction port and a grid, wherein the reamer body is assembled on the reamer shaft; the suction port is arranged on the assembled reamer body and is internally provided with the grid; and an annular reamer outer ring is arranged at the outer ring of the reamer body. The area ratio of suction port area to the whole area of the cutter is related to the soil property in working and ranges from 1/2 to 4/7, and the shape of the suction port is matched with that of the cutter. By adopting the technical scheme, the construction operating efficiency of the cutter suction dredger and the single-ship operating capability can be improved greatly.
Description
Technical field
The present invention relates to technical field of ships, refer in particular to a kind of reamer 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 objective of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, reamer 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 achieving the above object, technical scheme provided by the present invention is: a kind of reamer sucking hole device that is used for cutter suction dredger, it includes cutter hub, mangler shaft, suction inlet, grid, wherein, cutter hub is assemblied on the mangler shaft, cutter hub after the assembling is provided with suction inlet, and a grid is housed in the suction inlet, and the cutter hub outer ring is provided with the reamer outer ring of annular.
The area in the suction inlet zone of described suction inlet is relevant with the soil property of work with the area ratio of the overall region of cutter hub, and between 1/2 to 4/7, and its shape matches with cutter hub.
The shape of described grid is consistent with the shape of suction inlet inner chamber.
The present invention is after having adopted such scheme, after adopting this sucking hole device, can improve the work capacity of cutter suction dredger construction operation efficient and boats and ships list ship greatly, concentration of hydraulic mixture can improve 50% under all constant situation of miscellaneous equipment, and the grid at suction inlet place can prevent that non-essential foreign material from entering the mud quality after causing the suction inlet fault in the suction inlet or having influence on absorption.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Reference numeral: 1-cutter hub, 2-mangler shaft, 3-suction inlet, 4-grid, 5-reamer outer ring.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing 1, preferred embodiment of the present invention is: the described reamer sucking hole device of present embodiment includes cutter hub 1, mangler shaft 2, suction inlet 3, grid 4, wherein, cutter hub 1 is assemblied on the mangler shaft 2, and cutter hub 1 outer ring is provided with the reamer outer ring 5 of annular.Cutter hub 1 after the assembling is provided with suction inlet 3, and the area in the suction inlet zone of suction inlet 3 is relevant with the soil property of work with the area ratio of the overall region of cutter hub 1, and between 1/2 to 4/7, and its shape matches with cutter hub 1.After adopting this suction inlet 3, can improve the work capacity of cutter suction dredger construction operation efficient and boats and ships list ship greatly, concentration of hydraulic mixture can improve 50% under all constant situation of miscellaneous equipment, and a grid 4 is housed in the suction inlet 3, and the shape of grid 4 is consistent with the shape of suction inlet 3 inner chambers.Grid 4 can prevent that non-essential foreign material from entering the mud quality after causing suction inlet 3 faults in the suction inlet 3 or having influence on absorption.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
