加されて固化される。[Prior Art] As a conventional dredging device, there is a pump type. This pump-type dredging device has a large capacity pump installed on a ship,
Extend a hose from the pump to the bottom of the sea such as the seabed or lake bottom,
I try to suck up sludge with water. And
The sludge dredged in this way is mainly carried to a landfill by a carrier. At the landfill site, a solidifying agent and a coagulant are added to solidify.

るという欠点があった。[Problems to be solved by the invention] However, in the above-mentioned conventional dredging device, when the deposition depth of sludge is small, a part of the intake port of the dredging device is directly exposed to the bottom of the water and sucked up simultaneously with the sludge. The amount of water taken up is too large, and the solidifying agent cannot be mixed until after the treatment of residual water, and there is a disadvantage that the treatment of residual water requires a great deal of cost.

一部外周を覆うように形成されている。As shown in FIG. 2 which is a schematic cross-sectional view taken along the line II-II of FIG. 1, the lower part of the mud collecting plate 10 is formed so as to cover about half of the outer periphery of the tip end portion of the tubular casing 2. The screw conveyor 1 is arranged so as to be rotatable as indicated by an arrow W. That is, in the mud collecting plate 10, the rack gear 10a provided on the inner peripheral portion of the upper end thereof is always meshed with the output gear 18a of the hydraulic motor 18 attached to the tubular casing 2,
The motor 18 is driven so that it can turn. Reference numeral 19 is a bracket for supporting the mud collecting plate 10, and a bearing 20 is interposed between the bracket and the mud collecting plate 10. Also, the mud board 10
Is formed in a cylindrical shape, and is formed so as to partially cover the outer circumference of the cylindrical casing 2.

The drive device of the dredger (not shown) is operated to insert the tip of the vertical screw conveyor 1 into the sludge at the bottom of the water, and the drive device (not shown) of the screw shaft 3 is rotated, while simultaneously driving the screw shaft. A motor (not shown) is rotated. The rotation of the motor causes sludge to be taken into the cylindrical casing 2 through the opening 5.

まれ、水の浸入が防止される。Further, the dredging device is moved in a predetermined direction while the mud collecting plate 10 is inserted in the sludge, but at this time, the mud collecting plate 10 is swung rearward in the traveling direction (direction of arrow A) by the rotation of the motor 18. To be done. Therefore, during the progress, the sludge is pushed against the sludge collecting plate 10 to proceed, and the sludge is collected on the front side of the sludge collecting plate 10. Therefore, the opening 5 is always buried in the sludge, and substantially only the sludge is taken in from the opening 5, and the infiltration of water is prevented.

For example, the sludge discharged from the screw conveyor 1 is dumped to a landfill site via a carrier, a pressure-feeding hose, etc. after a solidifying agent is added and mixed.

進行方向とは逆の方向に来るようにすることもできる。In the above-mentioned embodiment, the mud collecting plate 10 is provided so as to be rotatable in the circumferential direction of the vertical screw conveyor 1, but this is fixed to the outer periphery of the cylindrical casing 2 so that the vertical screw conveyor 1 travels. It is also possible to change the direction of the entire vertical screw conveyor 1 according to the above so that the mud collecting plate 10 comes in the direction opposite to the traveling direction of the vertical screw conveyor 1.
