More specifically, a hydraulic cylinder 2 is fixedly arranged on the upper portion of the grab bucket base 11, the hydraulic cylinder 2 comprises a first hydraulic cylinder 2 and a second hydraulic cylinder 2, and the hydraulic cylinder 2 is used for adjusting the grab bucket through the hydraulic rod 3 to open or close the grab bucket; and one end of the hydraulic rod 3 is connected with the hydraulic cylinder 2, the other end of the hydraulic rod is movably connected with the grab bucket, and the hydraulic rod 3 comprises a first hydraulic rod 3 and a second hydraulic rod 3.

In detail, the left grab bucket 61 is connected to the first hydraulic cylinder 2 through the first hydraulic rod 3, and the right grab bucket 62 is connected to the second hydraulic cylinder 2 through the second hydraulic rod 3.

In more detail, the grab bucket is movably connected to the lower end of the grab bucket base 11 through a shaft pin 5, and the closing or opening of the grab bucket is adjusted through the extension or contraction of the hydraulic rod 3.

As shown in fig. 2, the grab base 11 further includes a movable spring 7 and a mud pipe interface 8, and the mud pipe interface 8 is movably connected with the grab base 11 through the movable spring 7. Specifically, a sludge discharge pipeline is externally connected to the sludge discharge pipe interface 8, sludge in the excavator bucket is cleaned and discharged through the sludge discharge pipeline, and the sludge discharge pipe interface 8 is made of an elastic material, so that the position of the sludge discharge pipe interface 8 is adjusted relatively; more specifically, activity spring 7 one end is connected in grab bucket base 11, the other end connect in mud pipe interface 8 is fixed relatively through activity spring 7 mud pipe interface 8 is used for the protection to support mud pipe interface 8 increases mud pipe interface 8's life, avoids appearing mud pipe interface 8 because of the flexible ageing phenomenon that appears of activity.

As shown in fig. 2, the grab bucket is divided into a left grab bucket 61 and a right grab bucket 62, the left grab bucket 61 and the right grab bucket 62 are symmetrically arranged on both sides of the grab bucket base 11, the end of the grab bucket is provided with a plurality of engaging teeth 7, the engaging teeth 7 are engaged with each other to form a sealed space when the grab bucket is closed, specifically, the end of the grab bucket is provided with a plurality of engaging teeth 7 for the grab bucket to more conveniently grab more sludge, and the engaging teeth 7 of the grab bucket are engaged with each other to form a sealed space when the left grab bucket 61 and the right grab bucket 62 are closed, so that a dredger can clean the sludge in the grab bucket through a sludge discharge pipe; more specifically, the left grab bucket 61 and the right grab bucket 62 are symmetrically arranged on both sides of the grab base 11, so that when the grab buckets are opened, the area of the left grab bucket 61 and the right grab bucket 62 capable of grabbing sludge is larger, and the structure of the grab buckets is more stable.

As shown in figure 2, the bottom of the grab bucket is V-shaped when the grab bucket is closed, and the bottom of the grab bucket is used for increasing the dredging depth of the grab bucket. In some embodiments, the opening of the grab bucket is in a V shape, so that the grab bucket can dig sludge to a deeper depth, and when the sludge discharge pipe cleans the sludge, the sludge slowly flows into the V-shaped bottom of the grab bucket, and the cleaning efficiency of the grab bucket is improved.

As shown in fig. 2, be provided with first dwang 81 in the left side grab bucket 61, be provided with second dwang 82 in the right side grab bucket 62, first dwang 81 one end swing joint in left side grab bucket 61, second dwang 82 one end swing joint in right side grab bucket 62, the first dwang 81 other end with second dwang 82 other end swing joint, it is specific, first dwang 81 one end rotate connect in left side grab bucket 61 is inboard, second dwang 82 one end rotate connect in right side grab bucket 62 is inboard, the first dwang 81 other end with the second dwang 82 other end rotates and connects, in some embodiments, the first dwang 81 other end through bolt swing joint in the second dwang 82 other end.

As shown in fig. 2, a sludge discharge pipe joint 9 is provided at a connection position of the first rotating rod 81 and the second rotating rod 82, the sludge discharge pipe joint 9 is connected to the sludge discharge pipe joint 8, specifically, a sludge pipe joint 9 is arranged at the joint of the first rotating rod 81 and the second rotating rod 82, when the grab bucket is opened, the first rotating rod 81 and the second rotating rod 82 are lengthened to drive the sludge discharge pipe joint 9 to move upwards, when the grab bucket is closed, the first rotating rod 81 and the second rotating rod 82 contract to drive the sludge discharge pipe joint 9 to move downwards, so that the working efficiency of cleaning sludge by the sludge discharge pipe joint 9 is improved, and when the grab bucket opens and falls into silt, first dwang 81 with the cooperation adjustment of second dwang 82 the area that opens of bucket avoids appearing because of opening the area too big, causes the muddy secondary pollution condition of silt when the grab bucket is closed.

When the grab bucket is in dredging operation, firstly, the first hydraulic cylinder 2 and the second hydraulic cylinder 2 are contracted to respectively drive the left grab bucket 61 and the right grab bucket 62 to be opened, the first rotating rod 81 and the second rotating rod 82 are in an extension stage, and the relative height of the mud pipe joint 9 is the highest. Secondly, the grab bucket is put down and wedged into the sludge by the self weight of the grab bucket. Then, first pneumatic cylinder 2 and the extension of second pneumatic cylinder 2 drive the hydraulic stem 3 and make left side grab bucket 61 with right side grab bucket 62 rotates around pivot 5, and then left side grab bucket 61 with the meshing of right side grab bucket 62 interlock tooth 7 makes the grab bucket closure forms confined space, first dwang 81 with second dwang 82 is in its connecting portion moves down in the grab bucket closure process, drives the mud pipe connector 9 that connects in its connecting portion and moves down, because silt has certain mobility in the grab bucket closure process, silt flows to the lower of V type grab bucket, and mud pipe connector 9 moves down simultaneously this moment, drives the mud pipe connector 8 that connects and moves down, and then makes silt carry to mud dumping ground along the mud pipe under the high pressure effect of mud pipe, accomplishes the work of clearance row and send silt. Thereby increasing the dredging effect of the bucket and improving the dredging work efficiency.

The above-mentioned embodiments are only one of the preferred embodiments of the present invention, and the ordinary changes and substitutions performed by those skilled in the art within the technical scope of the present invention should be included in the protection scope of the present invention.
