Description

The digging type dredge boat

Affiliated technical field:

The utility model relates to a kind of dredging water conservancy machinery,, exactly be a kind of digging type dredge boat.

Background technology:

Cutter suntion dredger is waterway dredging, blow the working ship that mud is built up fields, fill is commonly used, and this structure dredge boat blends clod by stirring trowel, and slush pump twists suction mud under water, is sent on the special-purpose mud carrier by dredging tube again, is transported to other places then and dumps.There is following defective in this technology: one,, then take tract because depositing the place of mud must be the low-lying land of no ponding, and of a high price, and do not do contaminated environment for a long time.Two, dredging and desilting often at the harbour, densely populated area such as industrial occupancy, business district, scenic spot, the mud that dredging is come out is not deposited at all with having and is digested, and the mud overwhelming majority that dredging is come out is a water, even designed watertight shutter, mud content still only accounts for a few percent, and operating efficiency is very low.

The utility model content:

In order to address the above problem, the utility model provides a kind of desilting efficiency data height, can directly take the digging type dredge boat of water-bed mud.

The technical solution of the utility model is: a kind of digging type dredge boat, comprise hull, sludger is equipped with at the bow place of hull, this sludger comprises dredge cutter and chain scraper slurry conveying machine, the cutter of dredging comprises the trowel axle of a horizontally set, is fixed with many handles on the trowel axle and is the staggered blade of dredging of 90 degree, and the trowel axle is connected with motor on being fixed in the chain scraper slurry conveying machine by transmission case, can order about down at this motor and rotate, trowel axle two ends are by the front end of bearing fixing in described slurry conveying machine; Described slurry conveying machine middle part is placed in the spill passageway of bow front end, the active thumb wheel of its rear end is fixed on the thumb wheel frame, this thumb wheel frame is hinged with the frame of dredging that is fixed on the boat deck, described slurry conveying machine is equipped with wire rope near the position of front end, and this wire rope is connected with hoist engine on the deck by the pulley that is arranged on the support.

The utility model is when carrying out dredging operation, loosen wire rope by hoist engine, make the slurry conveying machine front end rely on the own wt mud place that sinks under the water, opening motor then orders about the trowel axle by transmission case and revolves to dig and dredge, the mud that the scraper plate of slurry conveying machine will be dug out is scraped and is got and carry on the boat deck, simultaneously the wherein unnecessary river of elimination can be provided with conveyer belt under the slurry conveying machine rear end, can be transported to mud on the cargo ship or on the bank.

As further improvement of the utility model, the mud agitator can be set below the slurry conveying machine rear end, be provided with mixing plant in the bucket, the bucket wall is provided with water inlet pipe, dredging tube and slush pump, inject river by water pump the mud that digs is up stirred into mud, transfer out by flexible pipe then.

The beneficial effects of the utility model are not restricted by the depth in river course, and have only 20% from the mud water content that takes under water, and desilting efficiency data is very high, extensively is adapted to the dredging operation of rivers and lakes, reservoir.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described further:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is a vertical view of the present utility model.

The specific embodiment

Referring to accompanying drawing 1,2, a kind of digging type dredge boat, comprise hull 1, sludger is equipped with at the bow place of hull 1, this sludger comprises dredge cutter and chain scraper slurry conveying machine 2, the cutter of dredging comprises the trowel axle 13 of a horizontally set, be fixed with many handles on the trowel axle 13 and be the staggered blade 3 of dredging of 90 degree, trowel axle 13 is connected with motor 5 on being fixed in chain scraper slurry conveying machine 2 by transmission case 4, can order about down at motor 5 and rotate, trowel axle 13 two ends are by the front end of bearing fixing in described slurry conveying machine 2; Described slurry conveying machine 2 middle parts are placed in the spill passageway of bow front end, and the active thumb wheel 10 of its rear end is fixed on the thumb wheel frame 9, and this thumb wheel frame 9 is hinged with the frame 7 of dredging that is fixed on the boat deck.Motor 14 is connected with active thumb wheel 10 by reducer 12, and bigger torsion can be provided, and motor 14 is provided with overload protection arrangement simultaneously, shuts down in case the cutter of dredging is stuck or just snarls, and prevents to damage because of overload.Described slurry conveying machine 2 is equipped with wire rope 21 near the position of front ends, and this wire rope 21 is connected with hoist engine on the deck by the pulley that is arranged on the support 23.Support 23 crossbeam both sides also are provided with regulates wire rope 22, is used to regulate the inclination angle of support 23.

The utility model is when carrying out dredging operation, loosen wire rope 21 by hoist engine, make slurry conveying machine 2 front ends rely on the own wt mud place that sinks under the water, opening motor 5 then orders about trowel axle 13 by transmission case 4 and revolves to dig and dredge, the mud that the scraper plate 6 of slurry conveying machine 2 will be dug out is scraped and is got and carry on the boat deck, the wherein unnecessary river of elimination simultaneously, below, slurry conveying machine 2 rear ends is provided with mud agitator 15,16, be provided with turbine 24 in the bucket, water pump is by filler pipe 18,19 inject river, with turbine paddle 24 mud in the bucket is stirred into mud, be transported to mud on the cargo ship by slush pump 17 and dredging tube 11 then or on the bank.
