[0002] Dredgers are responsible for clearing silt from waterways and rivers to allow other vessels to pass smoothly. Not only do they ensure the smooth flow of waterways, but they are also crucial tools for land reclamation. Common types of dredgers include cutter suction dredgers and trailing suction hopper dredgers.

[0003] The existing patent CN114108727B, "A Deliverable Cutter for a Cutter Suction Dredger," describes a dredger comprising a connecting cylinder with a connecting flange fixedly at its rear end. A drive ring is coaxially and rotatably mounted on the front end of the connecting cylinder. A baffle plate with a mud inlet is also fixedly mounted on the front end of the connecting cylinder. A connecting ring is coaxially and detachably mounted on the drive ring, and a cutter body is detachably mounted on the connecting ring. A drive mechanism is connected to the drive ring, driving the drive ring to rotate the connecting ring, thereby causing the connecting ring to synchronously rotate the cutter body. A mud-crushing module is provided on the baffle plate, used to crush mud lumps about to be sucked into the mud inlet. By providing a mud-crushing module on the cutter, and using the rotating cutter to drive the mud-crushing module in a linear reciprocating motion, the mud-crushing mechanism can crush larger mud lumps entering the mud conveying pipe.

[0004] In actual use, although the strength of the reamer has been improved and its lifespan has been greatly extended, wear will still occur during long-term use, requiring replacement of the reamer. In existing equipment, the reamer is fixed with multiple bolts, which means that multiple bolts need to be tightened during disassembly and installation, resulting in low efficiency.

[0019] This utility model provides a cutter head for a cutter suction dredger used in hard strata, including a connecting cylinder 100 and a connecting assembly. The connecting assembly includes a connecting ring 101, a fixing block 102, a fixing ring 103, a body 104, an abutment block 105, and a driving component. The connecting ring 101 has an L-groove 106. The driving component includes a sliding block 107, a driving element, and a connecting base 108. The driving element includes a driving rod 109, a spring 110, and a driving ring 111. The connecting ring 101 has a stepped groove 112. This solution solves the problem that existing equipment uses multiple bolts to fix the cutter head, which requires unscrewing multiple bolts for replacement during disassembly and installation, resulting in low efficiency.

[0020] In this specific embodiment, the connecting cylinder 100 is the connecting cylinder described in the existing patent technology CN114108727B, "A Special Cutting Tool for Engineering Vessel Cutter Suction Dredger". One end of the connecting cylinder 100 is installed on the equipment, and the cutter is connected through the connecting cylinder 100. This solution enables quick installation and disassembly of the cutter, improving installation efficiency.

[0021] The connecting ring 101 is fixedly connected to the connecting cylinder 100 and located below the connecting cylinder 100. The fixing block 102 is slidably connected to the connecting ring 101 and located on the side of the connecting ring 101 away from the connecting cylinder 100. The fixing ring 103 is fixedly connected to the fixing block 102 and located on the side of the fixing block 102 away from the connecting ring 101. The body 104 is fixedly connected to the fixing ring 103 and located on the side of the fixing ring 103 away from the fixing block 102. On one side, the abutment block 105 is slidably connected to the connecting ring 101 and is located on the side of the connecting ring 101 near the fixing ring 103, and abuts against the fixing insert block 102. The connecting ring 101 is bolted to the connecting cylinder 100, so that the connecting ring 101 is stably installed on the equipment. The fixing insert block 102 is slidably installed on the connecting ring 101. The connecting ring 101 has a hole that mates with the fixing insert block 102, so that the fixing insert block 102 can rotate on the connecting ring 101. The fixed ring 103 is installed on the side of the fixed plug 102 away from the connecting ring 101. The fixed ring 103 is fixed to the connecting ring 101 by the fixed plug 102. The body 104 is the cutter structure described in the prior art patent CN114108727B, "A Cutter Head for a Cutter Suction Dredger for Engineering Vessels". The body 104 is fixedly installed on the fixed ring 103. The fixed plug 102 and the fixed ring 103 make the body... 104 is connected to the connecting ring 101. The abutment block 105 is installed inside the connecting ring 101 through the driving member. The driving member drives the abutment block 105 to move, so that the abutment block 105 abuts against the fixing insert 102, and the fixing insert 102 is fixed in the connecting ring 101. Then, the fixing ring 103 is stably installed on the connecting ring 101, so that the device can control the fixing ring 103, thereby realizing the ability to quickly install and remove the reamer and improving the installation efficiency.

[0022] Secondly, the L-groove 106 is located on the side of the connecting ring 101 away from the connecting cylinder 100 and cooperates with the fixing block 102. One end of the L-groove 106 extends out of the connecting ring 101, allowing the fixing block 102 to be inserted into the connecting ring 101. The size of one end of the L-groove 106 is equal to the sum of the lower end of the fixing block 102 and the lower end of the abutment block 105, so that when the abutment block 105 is stuck in the L-groove 106, it can abut against the fixing block 102. The other end of the L-groove 106 has the same size as the upper end of the fixing block 102, so that after the upper end of the fixing block 102 is inserted into the top side of the L-groove 106, it will not move up or down.

[0023] Simultaneously, the sliding block 107 is slidably connected to the connecting ring 101 and is located on the side of the connecting ring 101 away from the fixed insert 102; the connecting base 108 is connected to the sliding block 107 through the driving element, the driving element drives the connecting base 108 to move, the connecting base 108 is connected to the abutment block 105, and the sliding block 107 is slidably installed inside the connecting ring 101. The connecting ring 101 has a groove inside that mates with the connecting ring 101, allowing the sliding block 107 to move stably within the connecting ring 101. The connecting base 108 is bolted to the top of the abutment block 105. The connecting base 108 drives the abutment block 105 to move. The connecting base 108 is mounted on the sliding block 107 via the driving element. The driving element drives the connecting base 108 to move downward, causing the abutment block 105 to engage in the L-groove 106. The sliding block 107 drives the connecting base 108 to move, causing the connecting base 108 to move the abutment block 105 out of the L-groove 106, allowing the fixing insert 102 to move within the connecting ring 101.

[0024] Furthermore, the drive rod 109 is slidably connected to the sliding block 107 and is located on the side of the sliding block 107 away from the connecting ring 101, and is connected to the connecting base 108; the spring 110 is sleeved on the outside of the drive rod 109, and the two ends of the spring 110 are respectively connected to the sliding block 107 and the connecting base 108; the drive ring 111 is fixedly connected to the drive rod 109 and is located at the end of the drive rod 109 away from the connecting base 108, the drive rod 109 is slidably mounted on the sliding block 107, and the drive rod 109 moves through the sliding block 107 and the connecting base 108. The drive rod 109 enables the connecting base 108 to move up and down, and the sliding block 107 to move left and right. The spring 110 is sleeved on the drive rod 109, and the two ends of the spring 110 abut against the connecting base 108 and the sliding block 107 respectively. The spring 110 drives the connecting base 108 to move downward, so that the connecting base 108 drives the abutment block 105 to move. The drive ring 111 is fixedly installed on the upper end of the drive rod 109. Multiple drive rods 109 are connected through the drive ring 111, so that the drive ring 111 can drive multiple drive rods 109 to move simultaneously.

[0025] Finally, the stepped groove 112 is disposed on the side of the connecting ring 101 near the L groove 106. The stepped groove 112 cooperates with the abutment block 105. The stepped groove 112 is disposed inside the connecting ring 101. The stepped groove 112 allows the abutment block 105 to move inside the connecting ring 101, and the stepped shape allows the abutment block 105 to be fixed on the side of the connecting ring 101 away from the fixing insert 102.

[0026] Using a cutterhead from a cutter suction dredger for hard strata according to this embodiment, when the cutterhead needs to be replaced, firstly, the drive ring 111 pulls the drive rod 109, causing the connecting base 108 to move the abutment block 105 upward, so that the abutment block 105 leaves the L-groove 106. At this time, the drive ring 111 is rotated, causing the sliding block 107 to move and lock the abutment block 105 in the stepped groove 112. Then, the fixing ring 103 is rotated, causing one end of the fixing insert 102 to leave the upper end of the L-groove 106, allowing the fixing insert 102 to move up and down, so that the fixing insert 102 can slide out of the connecting ring 101. During installation, the operation is reversed, thereby achieving quick installation and disassembly of the cutterhead and improving installation efficiency.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
