The left connecting plate is disposed on one side of the right connecting plate, and a hydraulic drive device is fixedly connected to one side of the left connecting plate. A drive shaft is fixedly connected to one side of the hydraulic drive device, and a mounting base is provided on the outer side of the drive shaft. A protective cover is fixedly connected to one side of the mounting base, and a reinforcing plate is provided inside the protective cover. An outer moisture-proof plate is fixedly connected to the inner wall of the protective cover. This disc-type environmentally friendly dredging cutter head, by setting up a protective cover, an inner moisture-proof plate, an outer moisture-proof plate, a wear-resistant sealing layer, and a reinforcing plate, strengthens the load-bearing capacity and stability of the protective cover itself, extends the service life of the protective material and the protective cover, and solves the problem that the protective shell is thin and will be subject to huge impact forces after long-term use, making it prone to breakage and affecting normal use in the later stages. Existing long cutterheads, in actual use, are usually integrated, have a large driving force, and once the cutterhead itself is worn or gets stuck on a large rock, the entire cutterhead needs to be inspected and replaced.

Four sets of locking holes are opened on both ends of the auger body and the auger cap, and the auger body, the connecting steel pipe and the connecting steel pipe are fixedly installed by locking bolts passing through the multiple sets of locking holes.

[0009] When the cutter body rotates, the cutter blades dredge and agglomerate the underwater sludge, achieving the dredging and agglomerating effect. The cutter body, connecting steel pipe, and connecting steel pipe are connected and installed by locking bolts to ensure the fixation of the cutter body to the internal connecting steel pipe and connecting steel pipe, and the rotation and agglomeration effect is achieved as the connecting steel pipe and connecting steel pipe rotate.

[0010] As a further preferred technical solution of this utility model, a fixing block is welded and installed on the top of both the butt steel pipe and the connecting steel pipe, and the butt steel pipe and the connecting steel pipe are fixedly installed by fixing bolts passing through two sets of auger caps.

[0011] The connecting steel pipe is installed by connecting the two pipes together to facilitate the hydraulic transmission device. It also allows for segmented disassembly, making it easy to replace specific components and perform maintenance.

[0012] As a further preferred technical solution of this utility model; a connecting ring is welded and installed at one end of the inner wall of the connecting steel pipe, and two sets of welding blocks are welded and installed on the inner wall of the connecting steel pipe, and a positioning ring is welded and installed through the welding blocks. A reamer shaft is fixedly installed inside the positioning ring, and a snap-fit ​​end is fixedly installed at one end of the reamer shaft through the positioning ring. A connecting block is welded and installed on the inner wall of the connecting steel pipe on one side of the snap-fit ​​end, and one side of the connecting block is snap-fitted and installed with the snap-fit ​​end.

[0013] The cutter shaft is fixedly installed to the inner wall of the connecting steel pipe, ensuring the drive of the connecting steel pipe. This guarantees the stable rotation of the external cutter body, thereby achieving the effect of cleaning underwater sludge.

[0014] As a further preferred technical solution of this utility model, one end of the docking block is welded and installed with two sets of snap-fit ​​blocks through the auger cover, and the snap-fit ​​blocks are snapped and fixed with the rectangular corresponding grooves opened on the docking ring.

[0015] The connecting steel pipe and the docking steel pipe are secured by a snap-fit ​​mechanism with rectangular corresponding slots on the snap-fit ​​block and the docking ring. This ensures that the connecting steel pipe and the docking steel pipe are firmly locked together during rotation, preventing slippage and ensuring that the two sets of cutter bodies rotate in unison, thus preventing loosening of the cutter body and affecting its use. This extends the service life of the cutter, reduces the frequency of cutter body replacement, reduces the amount of metal material used in the production of the cutter body, and increases the environmental benefits of the cutter.

[0016] As a further preferred technical solution of this utility model; one end of the connecting steel pipe is fixedly installed to one end of the inner wall of the auger cover via a fixed bearing seat.

[0018] Beneficial effects

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The connecting steel pipe and the docking steel pipe are fixed by snapping together through the rectangular corresponding grooves on the snap-fit ​​block and the docking ring. This ensures that the connecting steel pipe and the docking steel pipe are firmly locked together during rotation, preventing slippage during rotation. This would avoid uneven rotation of the two sets of cutter bodies at their installation positions, which could lead to loosening of the cutter body installation and affect its use. This extends the service life of the cutter, reduces the frequency of cutter body replacement, reduces the amount of metal material used in the production of the cutter body, and increases the environmental protection effect of the cutter.

[0021] 2. The cutter body, connecting steel pipe, and connecting steel pipe are fixedly installed using locking bolts through multiple sets of locking holes. The connecting steel pipe and connecting steel pipe are also fixedly installed using fixing bolts through two sets of cutter end caps. Connecting the connecting steel pipe and connecting steel pipe allows for hydraulic transmission to drive them. This also allows for segmented disassembly, facilitating subsequent replacement of specific components and maintenance. Attached Figure Description

[0028] This specific embodiment is a long, environmentally friendly auger.

[0029] Existing long cutterheads, in actual use, are usually integrated, have a large driving force, and once the cutterhead itself is worn or gets stuck on a large rock, the entire cutterhead needs to be inspected and replaced.

[0030] Its structural diagram is as follows Figures 1-5 As shown. A long, environmentally friendly cutter head includes a cutter head cover 1 installed with the ship's lifting structure, two sets of cutter heads 2 rotatably installed inside the cutter head cover 1, a docking steel pipe 3 and a connecting steel pipe 4 fixedly installed with the two sets of cutter heads 2, and a hydraulic transmission device 5 installed at one end of the connecting steel pipe 4 for driving the cutter heads 2 to rotate. A side shell 11 is welded to one end of the cutter head cover 1, and the hydraulic transmission device 5 is fixedly installed inside the side shell 11. Underwater operations generally generate a certain water pressure, and the side shell 11 provides a certain degree of protection for the hydraulic transmission device 5. Multiple sets of cutter blades 21 are welded to the cutter heads 2. A cutter head cover 31 is welded to one end of both the docking steel pipe 3 and the connecting steel pipe 4.

[0031] Four sets of locking holes 23 are provided at both ends of the cutter body 2 and on the cutter end cap 31. The cutter body 2, the connecting steel pipe 3, and the connecting steel pipe 4 are fixedly installed by locking bolts 22 passing through multiple sets of locking holes 23. When the cutter body 2 rotates, the cutter blades 21 dig and shred the underwater sludge, achieving the sludge-dredging effect of the cutter. The cutter body 2, the connecting steel pipe 3, and the connecting steel pipe 4 are connected and installed by locking bolts 22, ensuring the fixing effect of the cutter body 2 with the internal connecting steel pipe 3 and connecting steel pipe 4, and achieving the rotational sludge-dredging effect as the connecting steel pipe 3 and connecting steel pipe 4 rotate. Fixing blocks 32 are welded and installed on the top of the connecting steel pipe 3 and connecting steel pipe 4. The connecting steel pipe 3 and connecting steel pipe 4 are fixedly installed by fixing bolts passing through two sets of cutter end caps 31. The connecting steel pipe 3 and connecting steel pipe 4 are connected and installed to facilitate the hydraulic transmission device 5 to drive them. It also has the effect of segmented disassembly, which facilitates the subsequent replacement of specific components and maintenance.

[0032] A docking ring 33 is welded to one end of the inner wall of the connecting steel pipe 3. Two sets of welding blocks 42 are welded to the inner wall of the connecting steel pipe 4, and a positioning ring 41 is welded to the welding blocks 42. A cutter shaft 6 is fixedly installed inside the positioning ring 41, and one end of the cutter shaft 6 passes through the positioning ring 41 and is fixedly installed with a snap-fit ​​end 61. A docking block 43 is welded to the inner wall of the connecting steel pipe 4 on one side of the snap-fit ​​end 61, and one side of the docking block 43 is snapped into the snap-fit ​​end 61. The cutter shaft 6 is fixedly installed to the inner wall of the connecting steel pipe 4 to ensure the drive of the connecting steel pipe 4. This ensures the stable rotation of the external cutter body 2, thereby achieving the effect of cleaning underwater sludge. Two sets of snap-fit ​​blocks 44 are welded to one end of the docking block 43 through the cutter cap 31, and the snap-fit ​​blocks 44 are snapped into the corresponding rectangular slots opened on the docking ring 33. The rectangular corresponding slots on the snap-fit ​​block 44 and the docking ring 33 ensure that the connecting steel pipe 4 and the docking steel pipe 3 are firmly locked together during rotation, preventing slippage and ensuring consistent rotation of the two sets of cutter bodies 2. This prevents loosening of the cutter body 2 and affects its use. This extends the service life of the cutter, reduces the frequency of cutter body 2 replacements, reduces the amount of metal used in the production of the cutter body 2, and increases the environmental benefits of the cutter. One end of the docking steel pipe 3 is fixedly installed to one end of the inner wall of the cutter cover 1 via a fixed bearing seat 12. The output end of the hydraulic transmission device 5 passes through the cutter cover 1 and the connecting steel pipe 4 and is fixedly installed to one end of the cutter shaft 6. The hydraulic transmission device 5 and the cutter shaft 6 are connected by a connecting seat 51. Starting the hydraulic transmission device 5 drives the cutter shaft 6 to rotate, thereby rotating the cutter body 2.

[0033] When the cutter head is in use, the hydraulic transmission device 5 drives the cutter shaft 6, causing the cutter shaft 6 to rotate, which in turn drives the connecting steel pipe 4 to rotate, and the connecting steel pipe 4 to rotate the docking steel pipe 3. With both the docking steel pipe 3 and the connecting steel pipe 4 rotating, the externally mounted cutter head 2 rotates to dredge and cut underwater sludge.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
