Description

Technical Field

[0001] The present application relates to the technical field of dredging equipment, and in particular to an adjustable cutter dredging device for a cutter suction dredger. Background Art

[0002] Cutter suction dredgers, also known as cutter suction dredgers, are mostly used in filling projects and are suitable for excavating riverbeds with loose soil such as sandy soil and silt. Cutter suction dredgers use cutters to break up the silt and then suck the silt out of the river channel through pipes for subsequent dredging.

[0003] An existing patent (publication number: CN221072785U) discloses an adjustable reamer, including a top plate and a bottom plate, with several mounting plates arranged between the top plate and the bottom plate, the mounting plates connecting the top plate and the bottom plate, and several cutter heads evenly arranged on the mounting plates, and the two ends of the mounting plates in the length direction are slidably arranged on the top plate and the bottom plate respectively.

[0004] The above-mentioned adjustable reamer has several return springs, and the return springs are respectively placed in the slide grooves, one end of the return spring is connected to the slider and the other end is connected to the slide groove. The return spring drives the slider to slide toward the direction close to the driving rod. During the overall rotation, when the speed is fast, the mounting plate is subjected to a large centrifugal force and is easy to move outward, resulting in poor stability of the cutter head during dredging, affecting the dredging effect. Secondly, the plug block is inserted into the slot and the bolt passes through the plug block and the cutter head to removably mount the cutter head on the mounting plate. The detachable setting of the cutter head can facilitate the replacement of the damaged cutter head when the cutter head is damaged. Since the cutter head is operated underwater for a long time, the bolts are prone to rust, which makes it difficult to disassemble and inconvenient to replace the cutter head. Utility Model Content

[0007] A penetrating connecting groove is provided on the surface of each mounting block, a cutter head is sleeved on the outer surface of each mounting block, a connecting block is slidably connected to the front and back of each cutter head, and each connecting block is plugged into a connecting groove adjacent to it.

[0008] Through the above scheme, the design of the mounting block, connecting groove and connecting block realizes the rapid disassembly and installation of the cutter head. The installation can be completed by simply fitting the cutter head with the mounting block, and the connection can be released by pulling the connecting block. This design not only simplifies the process of replacing the cutter head and reduces the difficulty of operation, but also effectively avoids the problem of disassembly difficulties caused by rusted bolts. The cutter plate is connected to the power disc through a hydraulic rod, and the inclination angle of the cutter plate can be adjusted according to actual needs, thereby optimizing the digging depth and range of the reamer. The application of displacement sensors realizes precise control of the displacement of the cutter plate, ensuring the accuracy and efficiency of dredging operations. The cutter head is made of high-hardness wear-resistant alloy steel, which has excellent wear resistance and corrosion resistance. It can remain sharp for a long time in harsh dredging environments, reducing the frequency of replacing the cutter head and reducing maintenance costs. At the same time, the connecting column and the cutter disc are fixed with bolts and provided with rubber pads for shock absorption, which is convenient for overall transportation and assembly.

[0009] Furthermore, the outer surface of the connecting column is fixedly connected to a power disk, and the outer surface of the power disk is hinged to multiple hydraulic rods, and the output end of each hydraulic rod is hinged to the blade adjacent to it.

[0010] Through the above solution, the inclination angle of the blade can be adjusted by controlling the extension and contraction of the hydraulic rod.

[0011] Furthermore, a group of springs are fixedly connected between each connecting block and the cutter head adjacent thereto.

[0012] Through the above solution, by setting the spring, the purpose of automatic resetting of the connecting block can be achieved, and the installation convenience of the cutter head can be improved.

[0013] Furthermore, both side edges of one end of each mounting block away from the blade are configured as bevels, and the top and bottom edges of each connecting block are configured as rounded corners.

[0014] Through the above solution and the above arrangement, it is possible to squeeze the two connecting blocks away from each other when the connecting block contacts the inclined surface of the mounting block.

[0015] Furthermore, the material of each of the cutter heads is high-hardness wear-resistant alloy steel.

[0016] Through the above solution, the material has excellent wear resistance and corrosion resistance, and can remain sharp for a long time in harsh dredging environments, thereby improving dredging efficiency, while reducing the frequency of replacing the cutter head and lowering maintenance costs.

[0017] Furthermore, a displacement sensor is installed inside one end of each blade.

[0018] Through the above solution, the displacement of the blade can be accurately controlled, thereby improving the accuracy and efficiency of dredging operations.

[0019] Furthermore, the connecting column and the cutter disc are fixedly connected by a plurality of bolts.

[0020] Through the above solution, the connecting column and the cutter head are connected with bolts, which facilitates overall transportation and assembly.

[0021] Furthermore, a rubber pad is provided between the connecting column and the cutter disc.

[0022] Through the above solution, the vibration and impact force generated during the dredging process can be effectively absorbed, the cutter head and connecting column can be protected from damage, and the stability and safety of the dredging operation can be improved.
