[0002] A dredging bucket of a dredger is disclosed in the Chinese utility model patent application number: CN202321494542.X, the structure of which includes a dredging bucket and a device plate, and the two sides of the outer periphery of the device plate are detachably mounted with a protective plate and a mesh plate, and the protective plate and the mesh plate are respectively integrally formed with a first ear plate and a second ear plate around them. The dredging bucket of the dredger can protect the outer side of the mesh plate inside the dredging bucket through a mesh protective plate on the outer side of the device plate, so that when the dredging bucket is digging the mud on the riverbed, the protective plate can protect the mesh holes on the surface of the mesh plate to prevent stones and sharp objects on the riverbed from squeezing the mesh holes on the surface of the mesh plate; however, by using the mesh plate to discharge the water above the silt, the silt in the bucket can be easily discharged together with the drainage hole.

[0003] Therefore, it is necessary to propose a dredging bucket for dredging to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of the utility model is to provide a dredging bucket of a dredger to solve the problem that the dredging bucket of the existing dredger proposed in the above background technology usually adopts a mesh plate to drain the water above the silt, but when the water is drained in this way, the silt in the bucket is easily discharged together with the water flow.

[0006] Preferably, there are two hanging ears, and the two hanging ears are symmetrically welded to the bucket body.

[0007] Preferably, there are multiple bucket teeth, and the multiple bucket teeth are welded to the bucket body at equal intervals along the longitudinal direction.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1: This embodiment 1 provides a dredging bucket for a dredger, which is directly improved on the dredging bucket of an existing dredger and has a unique structure. Figure 1-3As shown, it includes a bucket body 1, a hanging ear 2 is fixedly installed on the top of the right side of the bucket body 1, a bucket tooth 3 is fixedly installed on the left wall of the opening of the bucket body 1, a first reinforcing plate 6 and a third reinforcing plate 8 are fixedly installed on the front and rear side walls of the bucket body 1, and a plurality of second reinforcing plates 7 are fixedly installed at equal intervals on the bottom of the bucket body 1; there are two hanging ears 2, and the two hanging ears 2 are symmetrically welded on the bucket body 1, there are multiple bucket teeth 3, and the plurality of bucket teeth 3 are welded on the bucket body 1 at equal intervals along the longitudinal direction, the first reinforcing plate 6 is fixedly installed on the bottom of the bucket body 1, the second reinforcing plate 7 is fixedly installed on the top of the bucket body 1, and the first reinforcing plate 6 is arc-shaped, and the arc-shaped surface on the outer side of the first reinforcing plate 6 is flush with the bottom surface of the bucket body 1.

[0018] A rotating shaft 4 is fixedly installed in the bucket body 1 along the longitudinal direction, and the rotating shaft 4 is located at the top of the right side of the bucket body 1. A partition 5 is rotatably mounted on the rotating shaft 4, and the partition 5 divides the bucket body 1 into two left and right chambers. A plurality of water-permeable holes are vertically opened on the front and rear inner walls of the left chamber; a fixing plate 9 is fixedly installed in the water-permeable hole, and a through hole is opened on the fixing plate 9. A slide rod 10 is slidably installed in the through hole along the longitudinal direction, and one end of the slide rod 10 extends outside the bucket body 1 and is fixedly installed with a limit plate 11, and the other end extends into the bucket body 1 A sealing plate 12 is fixedly installed, and a spring 13 is mounted on the sliding rod 10 between the fixing plate 9 and the sealing plate 12; there are various ways to install the fixing plate 9, for example: a plurality of fixing rods are evenly fixedly installed along the circumference of the outer side of the fixing plate 9, and the other end of the fixing rod is fixedly connected to the bucket body 1, which can not only fix and support the fixing plate 9 but also does not affect the circulation of water. The water-permeable hole is a countersunk hole, which is compatible with the sealing plate 12. Setting the water-permeable hole as a countersunk hole can effectively enhance the sealing between the water-permeable hole and the sealing plate 12.

[0019] In the initial state, the spring 13 drives the sealing plate 12 to separate from the water permeable hole. When we use the dredging bucket to remove the silt at the bottom of the river, the dredging bucket will dig out the silt, and the bucket will inevitably contain a large amount of water. Moreover, since the specific gravity of silt is greater than that of water, according to common sense, the upper part of the bucket body is clear water, the middle part is a mixture of silt and water, and the lower part is silt; under the action of pressure, the water permeable hole in the middle and lower part of the bucket body 1 will be blocked by the sealing plate 12, and the water permeable hole in the upper part will remain open due to the smaller pressure. Thereby, the clean water in the upper layer can flow out slowly. During the flow of the clean water in the upper layer, the silt in the middle layer mixture will gradually settle to the lower layer under the action of gravity. In addition, due to the continuous loss of the clean water in the upper layer, the pressure on the sealing plate 12 in the middle of the bucket body 1 becomes smaller, thereby causing the water permeable holes in the middle to be reopened, so that the settled clean water is discharged from the bucket body 1. By utilizing the water pressure, the water permeable holes on the bucket body 1 are opened layer by layer, so that the device can better prevent the silt from flowing out of the dredging bucket with the clean water during the water filtering process.

[0020] When the water in the left chamber is emptied, the sludge can be unloaded. Since there is no water permeable hole in the right chamber, a certain amount of water is stored in the right chamber. When the sludge in the left chamber is gradually poured out, the partition 5 will shift under the action of its own weight and water pressure, so that the water in the right chamber can be discharged from the bottom into the left chamber to flush the sludge adhered to the bottom of the left chamber.

[0021] Embodiment 2: Embodiment 2 differs from Embodiment 1 in that, as shown, a tooth seat is fixedly mounted on the bucket body 1, and the bucket teeth 3 are fixedly mounted on the tooth seat by means of latches. The bucket teeth 3 are fixed by plugging, thereby facilitating replacement of the bucket teeth 3.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
