Abstract

The utility model relates to a dredging apparatus-a shovel-style dredger, in particular to a dredging apparatus for river channels. The utility model can be used by utilizing an old ship body and dynamic, driving, pushing equipment, etc and by being added with improved dredging equipment. The improved dredging equipment is characterized in that a dredge hopper is replaced by a shovel blade, a heavy mud delivering system is replaced by a light mud delivering belt, a mud protecting cover is added to avoid the mud waste, a sledge type gliding board is adopted to reduce the friction and to control the shovel blade to dredge, one dredging system is changed into two dredging system, and position-dredging is changed into all way-shipping for dredging all the way. The river bed is flat after being dredged, and the high work efficiency of the routine work of a storehouse and a quay in an operating area is not affected.

Description

Shovel-style dredger

The utility model earthmoving type dredger relates to the sludger of a kind of sludger, particularly river course.

In existing dredger, all have the low shortcoming of work efficiency: grab dredger is not that circulation is dredged, and can not employ one's time to the best advantage; Cutter suction dredger in the defeated mud of pipeline, because of earth than great, easily precipitation, stop up, must water down mud for water, actual ejection mud is few, and hull is huge, the preceding stern of ship, the steady mud of ripples deposits easily.Use for many years the entrance of Changjiang River, and it is little to produce effects; Though bucket chain dredge cycle operation continuously is because of dredging the location, whenever transposition, must stop work, and needing shift equipment, the riverbed that dug is uneven, big because of bucket weight again, many buckets and riverbed friction are very big, and power drain is many, and when bucket moves and turns to, because of nothing is protected mud equipment, waste mud is many.

The utility model earthmoving type dredger purpose is to propose the continuous sludger that a kind of equipment is simple, the mud degree of utilization is high.

The task of the utility model earthmoving type dredger is finished like this: the utility model earthmoving type dredger comprises hull, power, driving, propelling and earthmoving type sludger, and this sludger comprises perching knife, transmission shaft, defeated mud band, defeated bucket, accompanies axle, tripod pillar, slide plate, protects mud cover, two pin pillars, drops down mud groove, dump band and unload bucket.When hull advances, dredge continuously with perching knife, and push to the mud that is dug next from the knife back, enter by the rectangular mouth on the slide plate and to protect the mud cover, when defeated mud band enters and fills mud from protecting mud cover end opening, carry toward transmission shaft by anticlockwise direction from suitable for reading come out, the mud when transmission shaft turns to the below in the defeated bucket is poured into automatically and is dropped down the mud groove and drop down into cabin.

The utility model earthmoving type dredger compared with prior art has following advantage: the one tunnel navigates one the tunnel dredges, and the riverbed that dug is smooth, does not influence the routine of warehouse, operational zone harbour; The work efficiency height by designed capacity, surpasses than five times of the bucket chain dredge work efficiency of high efficiency.

Fig. 1 is the birds-eye view of the utility model earthmoving type dredger

Comprise by earthmoving type dredger shown in Figure 1: hull 1, perching knife 2, transmission shaft 3, defeated mud band 4, defeated bucket 5, accompany axle 6, tripod pillar 7, slide plate 8, protect mud cover 9, two pin pillars 10, drop down mud groove 11, dump band and unload bucket 12, also comprise power, driving, propelling and driving system in addition.(all not shown among the figure).

Transmission shaft 3 horizontal hull 1 forebodys that are contained in, outboard is stretched out at two ends, the left and right sides, respectively adorns three fixing tip toothed discs on projecting shaft, drives defeated mud band rotation, and two pin pillars 10 are adorned on the top, and dress drops down mud groove 11 and feeds cabins below the transmission shaft.

Accompany above the axle 6 tripod pillars 7 that are contained on the hull 1 latter half of slide plate 8, respectively adorn the tip toothed disc that three diameters are slightly less than the shaft gear dish.

Slide plate 8 adopts sledge types to be contained in width below the tripod pillar 7 and is greater than wide two times to three times of perching knife 2, and the middle part is opened one and is slightly larger than the wide oblong openning of perching knife.Bottom surface dress colter formula perching knife 2 or other perching knives.Utilize hull to advance, mud shovel is risen, push to, enter by the rectangular mouth on the slide plate and protect mud cover 9 from the knife back.About the slide plate front portion,, be buckled on the defeated mud band skeleton, help traction respectively by a chain cable.

Above the defeated mud band 4 many defeated buckets made from sheet steel or other materials 5 as Qian shape are installed, are made defeated mud band 4 become a succession of defeated bucket 5.The chain as three bicycle types is installed in the bottom surface.The skeleton of defeated mud band.Former and later two handles are respectively pressed upper bush, above two gloves on transmission shaft 3, below two gloves accompanying the axle 6 on.One on 1 meter of the every spacing of skeleton dress crossbeam with the copper pipe cover in the above, about with two pin pillars:

The most crash-resistant material of tripod pillar 7 usefulness is contained on the slide plate 8 that protects outside the mud cover 9, goes up by accompanying axle 6.

Protect mud cover oblong openning of Ge Kai about in the of 9, defeated mud band 4 enters from end opening, fills mud and goes out from suitable for reading.

The transmission shaft of dump band 12 upper ends will be a little more than embankment, and the axle of accompanying of lower end is contained in hull bottom.The light metal that an activity is installed below the dump mouth drops down the mud groove.Groove latter half of, the bipod pillar of dress activity.(will a little less than the middle part of the side)

The utility model earthmoving type dredger, can be dredged when hull moves continuously owing to adopt said structure.Be characterized in replacing dredge bucket with perching knife shovel mud, install additional and protect mud cover 9 and can reduce the mud waste, slide plate 8 adopts sledge types to reduce friction, control the perching knife degree of depth of dredging, and abolishes shift equipment and heavy a succession of defeated bucket, uses defeated mud band and light defeated bucket 5 instead.Prior art central authorities one place dredged to be changed about hull two places into and dredges, and utilizes obsolete vessel body and power thereof that dredging equipment is installed as far as possible, to reduce expenses.

Action operation: defeated mud band 4 is around transmission shaft 3 and accompany axle 6 by the anticlockwise direction rotation, enters from protecting mud cover 9 end openings, fills mud and comes out from suitable for reading, is transported to transmission shaft 3 and locates downwards, and mud is poured into automatically and dropped down mud groove 11, drops down into cabin.

The utility model earthmoving type dredger work efficiency is as follows:

1 large-scale dredger: perching knife is wide 1 meter, about two totally 2 meters, perching knife buries 0.2 meter and sets shipping agency speed per hour 5000m, 2000 cubic meters of per hour dredging.

2 middle-size and small-size dredgers: perching knife is wide 0.5 meter; About two totally 1 meter.Perching knife buries 0.2 meter, sets 3000 meters of shipping agency speed per hours, 600 cubic meters of per hour dredging.
