Technical Field
[0001] The present application relates to the technical field of dredging and sand dredging equipment, and in particular to a well-type grab dredging and dredging ship. Background Art
[0002] With the acceleration of urbanization and the continuous expansion of infrastructure construction, river dredging and port maintenance have become normal work. Traditional dredging methods are often inefficient and have a great impact on the environment. As a highly efficient underwater excavation and cleaning equipment, well-type grab dredging and dredging ships are widely used in port dredging, river cleaning and lake management because they can directly grab sand and silt underwater. This type of ship can effectively remove underwater obstacles and improve the traffic capacity of the waterway by using a grab for excavation, while reducing interference with the aquatic ecosystem.
[0003] At present, well-type grab dredging and dredging ships generally use hydraulic systems to control the opening and closing of the grab.

[0036] When in use, first start the driving assembly to drive the main wheel 4 to unwind and reel the traction chain 5, so that the main wheel 4 drives the synchronous wheel 1 21 to rotate, and the synchronous wheel 1 21 drives the two synchronous wheels 22 to rotate synchronously through the synchronous belt 23, so that the synchronous wheel 22 drives the two auxiliary wheels 19 to rotate synchronously with the main wheel 4, and completes the synchronous rewinding and unwinding of the auxiliary chain 20. At the same time, when the traction chain 5 pulls the traction head 6 and the bucket 7 to move up and down, the auxiliary chain 20 pulls one end of the traction head 6 to be tightened to both sides, thereby improving the stability of the bucket 7 during the lifting and lowering movement.
[0037] Reference Figure 2 and Figure 4 A drainage port 24 is provided at one end of the bucket 7 , a drainage plate 25 is hingedly connected to the interior of the drainage port 24 , and a resistance plate 26 that resists the drainage plate 25 is fixedly connected to one end of the interior of the drainage port 24 .

[0043] The implementation principle of a well-type grab sand dredging and dredging ship in this embodiment is as follows: first, the driving motor 18 is started to drive the driving worm 17 to mesh with the driving worm wheel 16, at which time the driving worm wheel 16 drives the main wheel 4 to rotate, and the main wheel 4 unwinds one end of the traction chain 5, so that the bucket 7 pulls the traction chain 5 through the wellhead 32 under the action of gravity and enters the underwater pre-excavation position, and at the same time, the bucket 7 drives the cone head 9 to form a conflict with the pre-excavation position, and then the hydraulic rod 8 and the vibration motor 10 are started, so that the vibration motor 10 drives the bucket 7 and the cone head 9 to vibrate, and the cone head 9 forms a preliminary crushing on the surface of the pre-excavation position, so that the cone head 9 can be inserted into the pre-excavation position; At the same time, the bucket 7 drives the follower slide bar 13 to slide along the length direction of the follower bin 11, and the follower slide bar 13 drives the counterweight 14 to squeeze the follower spring 15 along the length direction of the follower bin 11 to produce a contraction deformation, and at the same time, the rebound characteristic of the follower spring 15 is used to push the counterweight 14 to slide along the length direction of the follower bin 11, so that the counterweight 14 produces a continuous reciprocating movement along the length direction of the follower slide bar 13, so that the counterweight 14 drives the bucket 7 to produce a stronger shaking, and then the hydraulic rod 8 is used to drive the two buckets 7 to move together around the hinge axis, and close excavation is formed at the pre-excavation position; Then, when the traction chain 5 is driven in the reverse direction to pull the bucket 7 through the wellhead 32 and out of the water surface, the water flow pushes the drainage plate 25 to form a conflict with the contact plate 26 around the hinge shaft, and shields the drainage port 24, thereby reducing the water flow entering the bucket 7 through the drainage port 24 to disperse the materials inside the bucket 7. At the same time, the main wheel 4 drives the synchronous wheel 1 21 to rotate, and the synchronous wheel 1 21 drives the two synchronous wheels 22 to rotate synchronously through the synchronous belt 23, so that the synchronous wheel 22 drives the two auxiliary wheels 19 to rotate synchronously with the main wheel 4, and completes the synchronous winding and unwinding of the auxiliary chain 20. At the same time, when the traction chain 5 pulls the traction head 6 and the bucket 7 to move up and down, the auxiliary chain 20 pulls one end of the traction head 6 to tighten to both sides; Then, the electric slide rail 27 is started to drive the electric slider 28 to drive the bucket 7 to move along the length direction of the support frame 2 to the top of the filter box 29, and then the hydraulic rod 8 is started to drive the two buckets 7 to expand around the hinge axis, and the internal material is poured into the filter box 29 for screening, and then the conveyor 30 is started to transport the screened logistics in the filter box 29 to the storage box 31 for storage.
