[0002] Cutter suction dredgers, also known as cutter suction dredgers, are currently used for pre-construction desilting in inland rivers, lakes, and coastal ports. They are a predominant type of dredger. The cutter is the core component of a cutter suction dredger's underwater excavation. While not self-propulsive, cutter suction dredgers utilize a rotating cutter at their front end to loosen soil and sand from the river or seabed. This slurry is then drawn into the pump through a suction pipe and delivered to the discharge area through a discharge pipe. During operation, a cutter suction dredger integrates dredging, transporting, and unloading, achieving high production efficiency. They are suitable for dredging in inland rivers, lakes, and coastal ports with low winds and waves and low currents, and are particularly suited to dredging sand, sandy loam, and silt.

[0003] During the dredging process, the existing cutter head of the suction dredger is easily clogged by the endless stream of long drainage boards, branches and leaves, and various domestic garbage underwater. Once clogged, the cutter head is very troublesome to clean, affecting construction efficiency.

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] In one embodiment, Figure 1-Figure 5 As shown, a sand-taking device for dredging with a cutter suction ship comprises a cutter 1 and a protective cover 2. The cutter 1 comprises a large ring 3, a cutter arm 4, cutter teeth 5, and a hub 6. The side wall of the large ring 3 is fixedly connected to a number of cutter arms 4, and the side walls of the several cutter arms 4 are fixedly connected to a number of cutter teeth 5. The ends of the several cutter arms 4 away from the large ring 3 are commonly fixedly connected to the hub 6. The outer side wall of the large ring 3 is detachably connected to the protective cover 2. The outer side wall of the large ring 3 is provided with a mounting assembly for fixing the protective cover 2. A disassembly assembly is provided inside the large ring 3 for facilitating the disassembly of the protective cover 2. During the dredging process, the cutter 1 of the cutter suction dredger is blocked by a continuous stream of long drainage boards underwater, and it is very troublesome to clean the cutter head. Based on this, a protective cover 2 is installed on the large ring 3 of the cutter 1. Through the protective cover 2, the long drainage boards, branches and leaves, and various domestic garbage that are absorbed are continuously blocked during the rotation of the cutter head, which can significantly reduce the external large-particle garbage entering the cutter head, avoid the cutter head from stopping due to too much debris, and affect the construction efficiency.

[0027] In one embodiment, Figure 4 and Figure 5 As shown, the mounting assembly includes a clamping block 7. Four clamping block grooves 9, each of which is opposed to the other, are defined on the outer wall of the large ring 3. A clamping block 7 is slidably connected to the inner wall of each of the four clamping block grooves 9. A damping spring 8 is fixedly connected between the clamping block 7 and the inner wall of the clamping block groove 9. The side wall of the protective cover 2 is defined with four grooves corresponding to the clamping blocks 7, and the clamping blocks 7 engage with the grooves. When the protective cover 2 is mounted on the large ring 3, the clamping block 7 and the damping spring 8 cooperate. When the grooves of the protective cover 2 correspond to the clamping block 7, the clamping block 7 engages with the grooves of the protective cover 2 under the action of the damping spring 8, quickly securing the protective cover 2.

[0028] In one embodiment, Figure 4 and Figure 5 As shown, the side wall of the clamping block 7 outside the clamping block groove 9 is provided with a chamfer, which makes the clamping of the clamping block 7 smoother.

[0029] In one embodiment, Figure 4 and Figure 5 As shown, the side wall of the block 7 located in the block groove 9 is provided with a protrusion, and the protrusion of the block 7 is slidably connected to the inner side wall of the block groove 9. The protrusion can play a role in limiting the block 7.

[0030] In one embodiment, Figure 4 and Figure 5 As shown, the disassembly assembly includes a limit plate 10 and a pull rod 12. Four limit plate grooves facing each other are opened on the inner side wall of the large ring 3. The inner side walls of the limit plate grooves are all slidably connected to the limit plates 10. The side walls of the limit plates 10 located in the limit plate grooves are rotatably connected to the pull rods 12 through bearings. The pull rods 12 extend through the block grooves 9 and are fixedly connected to the side walls of the block 7. When the protective cover 2 needs to be disassembled and replaced, the pull ring 11 is pulled, and the pull ring 11 drives the limit plate 10 to move out of the limit plate groove and rotate ninety degrees. After rotating ninety degrees, it can be stuck outside the limit plate groove. At this time, the limit plate 10 drives the pull rod 12 to move, and the pull rod 12 drives the block 7 into the block groove 9, so that the block 7 is disengaged from the groove of the protective cover 2.

[0031] Example 2

[0032] In one embodiment, Figure 2 and Figure 5 As shown, the limiting plate 10 is a rectangular parallelepiped. Since the limiting plate 10 is a rectangular parallelepiped, it can be stuck outside the limiting plate slot after rotating ninety degrees.

[0033] In one embodiment, Figure 4 and Figure 5 As shown, a pull ring 11 is fixedly connected to the side wall of the limiting plate 10 away from the pull rod 12, and the pull ring 11 is engraved with anti-slip lines. The pull ring 11 facilitates pulling the limiting plate 10 out of the limiting plate slot.

[0034] In one embodiment, Figure 1 and Figure 2 As shown, the side wall of the protective cover 2 is provided with a plurality of holes, which are convenient for passing mud and sand, and prevent long drainage boards, branches and leaves, and various household garbage from entering.

[0035] The above embodiment discloses a sand collecting device for dredging with a cutter suction vessel. The protective cover 2 is mounted on the large ring 3. Through the cooperation of the clamping block 7 and the damping spring 8, when the groove of the protective cover 2 corresponds to the clamping block 7, the clamping block 7 is engaged with the groove of the protective cover 2 under the action of the damping spring 8, thereby quickly fixing the protective cover 2.

[0036] When the protective cover 2 needs to be disassembled and replaced, the pull ring 11 is pulled, and the pull ring 11 drives the limit plate 10 to move out of the limit plate groove and rotate 90 degrees. Since the limit plate 10 is a rectangular parallelepiped, it can be stuck outside the limit plate groove after rotating 90 degrees. At this time, the limit plate 10 drives the pull rod 12 to move, and the pull rod 12 drives the clamping block 7 into the clamping block groove 9, so that the clamping block 7 is released from the groove of the protective cover 2. The protective cover 2 is a steel protective net.

[0037] During the dredging process, the cutter 1 of the cutter suction dredger is blocked by a continuous stream of long drainage boards underwater, and it is very troublesome to clean the cutter head. Based on this, a protective cover 2 is installed on the large ring 3 of the cutter 1. Through the protective cover 2, the long drainage boards, branches and leaves, and various domestic garbage that are absorbed are continuously blocked during the rotation of the cutter head, which can significantly reduce the external large-particle garbage entering the cutter head, avoid the cutter head from stopping due to too much debris, and affect the construction efficiency.

[0038] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
