Abstract

The utility model relates to an underlying mud supplying shovel of a pneumatic dredge pump, which adopts the structure that three to nine pump body are welded together to form a group; an air inlet pipe and a mud discharging pipe are respectively fixed at the upper part in each pump body; an A cover plate is hinged with the upper end of each mud discharging pipe; the air inlet pipes are gathered to form an air inlet main pipe, and the mud discharging pipes are gathered to form a mud discharging main pipe; Two mud sucking pipes are respectively fixed below each pump body; a B cover plate is hinged with the upper end of the mud sucking pipe; the axial line of each group pump body is vertically welded and fixed with the pulling direction of forward motion; one end of each pump body is pulledand warped upwards; an inclined hopper with a plane bottom is respectively welded at the sealing head of two ends of each pump body and outside each pump body; the mud supplying shovel on the bottom surface of each inclined hopper is positioned at the lower end of the pneumatic dredge pump; an inclined barrier is fixed in each inclined hopper; each inclined barrier is divided into two sections andfixedly welded with each inclined hopper; the upper end of each barrier adopts a steel plate, and the lower end thereof is welded by using a bar steel and takes the shape of a grid; and a wire cabletugged by a ship on the sea penetrates the inclined hoppers. The underlying mud supplying shovel has the advantages of simple structure, convenient operation, environmental protection, high efficiencyand low cost, and can increase the concentration of sucked mud by 20 percent to 30 percent.

Description

The pneumatic dredge pump of underneath type advances mud shovel

Technical field

The utility model relates to a kind of dredge pump and advances mud shovel, particularly relates to a kind ofly advancing the pneumatic dredge pump of underneath type that mud shovel is fixed on every group of pneumatic dredge pump below and advancing mud shovel.

Background technique

As everyone knows, at present, various pneumatic dredge pumps advance mud shovel, all place the pump housing to be separate state outward, upper strata or water all around can enter when advancing mud, thereby reduced to suck the concentration of mud, increased workload, efficient is low, labor intensity is big, the cost height also can polluted seawater in case the muddy water overflow occurs, influences the clarity of seawater.

Summary of the invention:

Main purpose of the present utility model is to overcome above deficiency and provides a kind of and simple in structure, easy to use advance the pneumatic dredge pump of underneath type that mud shovel is fixed on every group of pneumatic dredge pump below and advance mud shovel.

The technological scheme that its technical problem that solves the utility model adopts is: it comprises the pump housing, suction tude, sludge drainage pipe, dredging tube and wire rope, it is characterized in that: the use welded together of the pump housing of one group of pneumatic dredge pump, the top of each pump housing is fixed with suction tude and sludge drainage pipe respectively, the upper end of sludge drainage pipe is hinged with the A cover plate, suction tude on all pump housings is aggregated into house steward A with pipeline, all sludge drainage pipes are aggregated into house steward B with pipeline, the bottom of each pump housing is fixed with two dredging tubes respectively, the upper end of dredging tube has hinged B cover plate, the vertical welding with the direction of advance of pulling of the axis of every group of pump housing is fixing, the end that every group of pump housing is pulled is upturned, the outside at every group of pump housing lower end and two ends end socket place is welded with the tipping bucket that the bottom is the plane, the rear end and the pump housing of tipping bucket are shut, the lower plane of tipping bucket is that into mud shovel is that the lower plane of tipping bucket is that into mud shovel promptly enters the lower end that mud shovel places the pneumatic dredge pump pump housing, tipping bucket opening end internal fixation has the fence of inclination, fence is divided into two sections, the epimere of fence is a steel plate, the weldering of steel plate and fence and tipping bucket is dead, at the both sides of tipping bucket opening end reeve with the ship haulage cable on the sea.

The utility model can also adopt following technical measures: described one group of pump housing is 3-9.

Advantage and the good effect that the utlity model has are: advance the front end that mud shovel places pneumatic dredge pump below tipping bucket, and simple in structure, be convenient to operation, environmental protection is good, and inhaling mud concentration can increase 20--30%, the efficient height, cost is low.

Description of drawings

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

Among Fig. 1: 1. the pump housing, 2. suction tude, 3. sludge drainage pipe, 4.A cover plate, 5. dredging tube, 6.B cover plate, 7. tipping bucket, 8. fence, 9. steel plate, 10. wire rope, house steward 11.A, house steward 12.B.

Embodiment

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.

As shown in Figure 1: the pump housing 1 one-tenth welded together of the utility model 3-9 pneumatic dredge pump is united use for one group, the top of each pump housing 1 is fixed with suction tude 2 and sludge drainage pipe 3 respectively, the upper end of sludge drainage pipe 3 is hinged with A cover plate 4, suction tude 2 usefulness pipelines on all pump housings 1 are aggregated into house steward A 11, all sludge drainage pipe 3 usefulness pipelines are aggregated into house steward B 12, the below of each pump housing 1 is fixed with two dredging tubes 5 respectively, the upper end of dredging tube 5 has hinged B cover plate 6, the lower end of dredging tube 5 is stretched out outside the pump housing 1 and is communicated with tipping bucket 7, the vertical welding with the direction of advance that is spurred by wire rope 10 of the axis of every group of pump housing 1 is fixed into one, because of every group of fixing 3-9 pump housing 1, so big efficient height of power, the end that every group of pump housing 1 is pulled is upturned, the outside at the every group of pump housing 1 two ends end socket and the pump housing 1 place is welded with the tipping bucket 7 that the bottom is horizontal plane, the lower plane of tipping bucket 7 is that into mud shovel promptly enters the lower end that mud shovel places the pneumatic dredge pump pump housing 1, shut the rear end of tipping bucket 7, seawater around the outside can't enter in the tipping bucket 7 that is closed shape, inhale mud concentration thereby can increase, tipping bucket 7 internal fixation have the fence 8 of inclination, two sections on fence 8 minutes, the epimere of fence 8 is that steel plate 9 is dead with tipping bucket 7 welderings, enter in the tipping bucket 7 with seawater around further preventing, its hypomere is welded into lattice-shaped with the bar steel, can stop that booty enters in the tipping bucket 7 in the seawater, ship haulage cable 10 on the both sides reeve 10 usefulness seas of tipping bucket 7 opening ends advances this equipment.

During use, the effect of advancing mud shovel has been played in the bottom of 10 tipping bucket 7 front ends of pulling wire rope, and bottom silt is scooped up in the propelling tipping bucket 7, under the effect of pressure, the cover plate 5 of two dredging tubes 4 is opened, at this moment, under the pulling of wire rope 10, tipping bucket 7 advances continuously, after bottom silt is scooped up, enter discontinuously in the pump housing 1, till filling by two dredging tubes 5, at this moment, the B cover plate 6 of two dredging tubes 5 is closed, and then, feeds high pressure air in house steward A 11 that suction tude 2 gathers, the A cover plate 4 that increases sludge drainage pipe 3 upper ends because of the pump housing 1 internal pressure backs down, mud in the pump housing 1 is discharged by house steward B 12 of sludge drainage pipe 3, and according to aerodynamic principle, this dredge pump sucks bottom silt flatly flatly, seawater because of the outside can't enter in the tipping bucket 7 that is closed shape again, so along with the reach of equipment, and improved the concentration of the mud that shovels out, can increase suction mud concentration 20--30% usually in the seabed.

Its advantage is: simple in structure, and convenient operation, environment protecting is good, and inhaling mud concentration can increase 20--30%, The efficient height, cost is low.
