Abstract
The invention relates to a roll-suction type dredging head for a dredging ship. The roll-suction type dredging head for the dredging ship comprises a dredging head body, a walking frame and a mud discharging pipe, wherein one end of the walking frame is movably connected with the center of the ship edge of the head of a ship hull, the other end of the walking frame is connected with the dredging head body, a mud sucking opening of the mud discharging pipe is located in the dredging head body, and the dredging head body is a spherical frame body defined by a plurality of warp-wise steel rings of the same size and a plurality of weft-wise steel rings of the same size. A plurality of soil-breaking blades are evenly arranged on the outer circumference of the warp-wise steel rings and the weft-wise steel rings at equal angles, the walking frame is a hollow steel pipe, the end, connected with the dredging head body, of the walking frame is connected with the mud sucking opening, a bent pipe is arranged in the middle of the walking frame, and the bent pipe is connected with the mud discharging pipe.
Description
Technical field
The present invention relates to water body desilting field, exactly relate to a kind of dredger with rolling suction desilting
Head.
Background technology
Conventional desilting equipment all exists and back-silts seriously at present, and secondary pollution is caused in construction waters, causes desilting defective.Particularly the desilting of protecting territory ditch, tap water water conservation district, lake and tourist attractions of cleaning need to not reach high desilting density, energy-saving and environmental protection, ecological dredging for many years.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservationly, the dredger of environment-friendly high-efficiency is with rolling suction desilting head.
The technical scheme that the present invention takes is:
A kind of dredger is with rolling suction desilting head, comprise desilting head, row frame and mud pipe, row frame one end is flexibly connected the center on hull head ship edge, the other end connects desilting head, the mud suction mouth of mud pipe is positioned at desilting head, the spherical frame body of described desilting head for being surrounded by the identical warp-wise steel ring of some sizes and some broadwise steel rings varying in size, in described warp-wise steel ring and broadwise steel ring outer circumference, impartial even angle is provided with some blades that break ground, described row frame is hollow steel tube, it is connected with mud suction mouth with one end that desilting head is connected, row frame middle part be provided with bend pipe, described bend pipe is connected with mud pipe.
Further, described each warp-wise steel ring is connected with steel ring isoplanar with the blade that breaks ground in broadwise steel ring outer circumference.
Further, row frame head is fixed in diametric one end of described desilting head, and the other end is fixed in its inner mud suction mouth through minor axis.
Further, on described desilting head, be provided with environmental protection case.
Further, described mud pipe is connected with separate unit or many sludge pumps.
Further, described mud suction mouth is horn-like bend pipe.
Again further, it is characterized in that, described mud suction mouth horn mouth is for arranging down.
The present invention adopts the beneficial effect of above technical scheme to be:
(1) roll suction desilting head and adopt spherical desilting head, on desilting head, be welded with the crisscross blade that breaks ground, desilting head is without power drive, when the reductor on hull drives row frame lifting and moves left and right, the desilting of breaking ground at the bottom under self gravitation effect of desilting head, simple in structure, without power, save the energy.
(2) on desilting head, be provided with environmental protection case, in desilting process, prevent from that underwater mud and impurity are general before being sucked away to the water surface, to cause secondary pollution, environmental protection more.
(3) adopt the capable frame of hollow structure, row frame head connects mud suction mouth, and middle part connects mud pipe through bend pipe again, and row frame plays the effect of mud pipe simultaneously, has saved pipeline and space, and structure is compact and reasonable more.Mud suction mouth adopts down horn-like, and dredging tube can connect one or more slush pump, and the efficiency of inhaling mud is higher, and desilting is more complete.
Accompanying drawing explanation
Fig. 1 is embodiments of the invention figure.
In figure: row frame 1, bend pipe 2, mud suction mouth 3, desilting 4, end axle 5, the blade 6 that breaks ground, warp-wise steel ring 7, broadwise steel ring 8, environmental protection case 9.
The specific embodiment:
In figure, a kind of dredger comprises row frame 1 with rolling suction desilting head, bend pipe 2, and mud suction mouth 3, desilting 4, end axle 5, blade 6 and environmental protection case 9 break ground.The afterbody of described row frame 1 is connected in the center on hull head ship edge through universal joint, head and horn-like port mud suction mouth 3 is down welded to connect, the leading portion of row frame 1 is hollow steel pipe, its hollow parts is provided with bend pipe 2, described bend pipe 2 connects one or more sludge pump through mud pipe, a described desilting 4 spherical frame body that formed by the identical warp-wise steel ring 7 of some sizes and some broadwise steel ring 8 Combination Welding that vary in size, in described warp-wise steel ring 7 and broadwise steel ring 8 outer circumference, impartial even angle is provided with some blades 6 that break ground, each warp-wise steel ring 7 is connected with steel ring isoplanar with the blade that breaks ground in broadwise steel ring 8 outer circumference, desilting 4 one end are welded on row frame 1, its diametric other end is welded in mud suction mouth 3 through minor axis 5, desilting 4 top are also provided with hemispheric environmental protection case 9.
Its operating principle is: the hoist engine on hull pulls row frame 1 to drive desilting 4 to move up and down by steel cable or during side-to-side movement, the blade 6 that breaks ground in desilting 4 breaks ground at the bottom under Action of Gravity Field, the mud being broken out upwards floats and concentrates in environmental protection case, and described horn-like mud suction mouth 3 is drawn into the mud pipe of row frame 1 hollow section through being connected with bend pipe 2 by mud and is discharged to the mound field on riverbank.
