However, when excavating the water bottom with a bucket wheel type excavation device, the soil sucked up by the bucket 2b is lifted above the suction port 5, and then falls into the suction port 5 by the action of gravity, and is absorbed together with the surrounding water. It is sucked up by a pump, and when several buckets 2b rotate in sequence to excavate the earth and sand at the bottom of the water and suck it upward, some of the earth and sand thrown out to the outer periphery by the rotation of the buckets 2b absorbs the surrounding water. There was a problem that the water was contaminated, and furthermore, the mud content was low.

Therefore, the present invention solves the problems of the conventional method by preventing the soil from being scattered around even if some of the soil is thrown out when the bucket excavates and sucks up the soil while rotating, and also prevents foreign matter from being sucked in. The aim is to prevent this from happening.

The present invention provides a bucket wheel type excavation equipment in which a cover that covers the upper half of the bucket wheel is fitted onto the rotating shaft of the bucket wheel, and a plurality of downwardly extending holes are provided on both sides of the front end of the cover. It has a configuration with a cutter attached.

When the bucket of the bucket wheel rotates and sucks up the excavated soil, some of the soil that is thrown outward due to centrifugal force due to the rotation of the bucket is stored in a dam inside the cover that covers the upper half of the bucket wheel. It is dropped into the suction port position in a stopped state. Further, when the ladder is swung from side to side, unnecessary objects such as dust in the direction of swing are pushed away by the cutters attached to both sides of the front end of the cover, so that such unnecessary objects are no longer sucked up by the bucket.

FIG. 1 shows an embodiment of the present invention, in which a bucket wheel 2 is rotatably attached to the tip of a rudder 11 that is attached to the bow of a dredger so that it can rise and fall freely, and the bucket wheel 2 is grounded on the bottom of the water. In the configuration in which excavation is performed by swinging the bucket wheel 2 left and right while rotating, a cover 12 is provided to cover the upper half of the bucket wheel 2 when the bucket wheel 2 is in an excavating position. The cover 12 has a hollow semicircular shape as shown in FIG. 2, and each left and right plate has a rotating shaft 3 of the bucket wheel 2 (see FIG. 4) in the center. It has a hole 13 for insertion, and a plurality of cutters 4 of a required length are attached downwardly at required intervals to the front end of each of the left and right frames so as to push away foreign matter during excavation.

Now, when the hull is fixed with the stern spats and the bucket wheels 2 are rotated and the bucket wheels 2 are swung from side to side along with the rudder 11, each bucket 2b of the rotating bucket wheels 2 will move the earth and sand at the bottom of the water. It is scooped up and lifted one by one, dropped into the suction port position, and sucked up through the suction pipe 6 by the pump on the hull. At this time, due to centrifugal force caused by the rotation of the bucket wheel 2, some of the dirt scooped up by the bucket is thrown outward, but this thrown dirt is caught by the cover 12 and can be scattered around. It disappears. This prevents the surroundings from being polluted. or,
Since some of the earth and sand caught by the cover 12 is sucked up by the pump, the mud content can be improved compared to the case without the cover 12.

The above is an embodiment of the present invention, and a case where the cover 12 is fixed is shown, but it is possible to make the cover 12 rotatable in the front and back direction, and to install a cylinder device or the like between the top of the cover 12 and the ladder 11. Intermediate,
The cover 12 can always cover the upper half of the bucket wheel 2 even when the dredging water depth H is shallow. According to this embodiment, the relative angle with the rudder 11 can be freely changed whether the depth of the dredging water is shallow or deep, and the cover can always be kept in the proper posture as shown in FIG. 1 during excavation.

The reason why the cover 12 is semicircular is to prevent the cover from hitting the bottom surface and getting in the way when the bucket wheel 2 is lowered to the bottom surface and digging begins. However, once excavation has started, it is better to cover the rear of the bucket wheel 2 so that earth and sand do not escape to the rear. Therefore, in the present invention, a sliding cover 15 as shown by the two-dot chain line in FIG.
The sliding cover 15 may be attached so as to be rotatable around the ladder 11, and the sliding cover 15 may be supported via a cylinder device 16 with respect to the ladder 11.
According to this embodiment, the sliding cover 15 is stored in the cover 12 before the start of excavation, and after the start of excavation, it is pulled out from inside the cover 12 downward by the cylinder device, so that it does not get in the way. The rear side of the bucket wheel 2 can be covered without any problems.

Note that the present invention is not limited to the above-described embodiments; for example, the shape of the cover 12 may be
Figure 2 shows the case where the lower ends of the left and right plates and the front and rear plates are straight, but the lower edges of both plates are shaped so that they spread outward, so that they can be placed on them without digging into the sediment at the bottom of the water. Good too.

As described above, according to the bucket wheel excavator for dredging of the present invention, it is possible to prevent part of the earth and sand from scattering and polluting the surrounding area during excavation with the bucket wheel, and it is covered with a cover to prevent mud from being contaminated. In addition, the foreign matter is pushed away by the cutter and is not sucked in, eliminating the risk of clogging the pump, and other excellent effects can be achieved.
