Description

Technical Field

[0001] The utility model relates to the technical field of dredgers, in particular to a novel dredger suction head. Background Art

[0002] The task of a dredger is to carry out underwater earthwork construction, specifically deepening, widening and clearing existing waterways and ports, excavating new waterways, ports and canals, dredging the foundation trenches of docks, shipyards, locks and other hydraulic structures, as well as throwing the excavated mud into the deep sea or blowing it into land depressions to create farmland, etc. It is a powerful tool for blowing sand and filling the sea.

[0003] However, the blades at the faucet of the existing dredger suction head are mostly of uniform shape or spiral blade shape, and the overall crushing effect is relatively poor, and the strangulation force generated cannot be more effectively diffused, especially when encountering some blocky mud and sand, which cannot be fully cut and crushed, resulting in large mud and sand particles sucked by the suction pipe, and sometimes even clogging the suction pipe. In addition, the faucet part has insufficient crushing force, and the greater the resistance during rotation, it is easy to affect the efficiency of dredging. Moreover, the dredging range and efficiency are relatively poor if only the front end faucet is used for crushing. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel dredging vessel auger suction head, which can enhance the crushing effect of the auger head and improve the efficiency of dredging and suction.

[0030] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0031] like Figure 1-7As shown, in this embodiment, a new type of dredger suction head is provided, which is mainly composed of a mounting body 1, a drive shaft 2, a auger faucet structure, four mud suction pipes 7 and other components. Among them, the drive shaft 2 passes through the mounting body 1 and is rotatably mounted through a bearing, the auger faucet structure is mounted at the front end of the drive shaft 2, and the rear end of the drive shaft 2 is directly connected to the mechanical arm equipment on the dredger. The rotation of the drive shaft 2 can drive the auger faucet structure to rotate and crush the mud and sand to perform dredging. The four mud suction pipes 7 pass through the mounting body 1 for fixing, and are distributed in a circular array around the drive shaft 2. The front ends of the four mud suction pipes 7 are close to the auger faucet structure, and the rear sections of the four mud suction pipes 7 are connected to the mud suction equipment on the dredger. When the auger faucet structure is broken for dredging, the four mud suction pipes 7 can absorb the crushed mud and sand, and then transmit it to the dredger for storage and transfer.

[0032] In order to make the auger faucet structure obtain better crushing effect, the auger faucet structure in this embodiment is specifically composed of a conical frame 3 and a plurality of separate blades 4 and an integrated blade 5. The conical frame 3 is installed at the front end of the driving shaft 2, and the plurality of separate blades 4 and the plurality of integrated blades 5 are arranged and distributed in a staggered manner. Such a design enables the auger faucet to effectively disperse the strangulation force during rotational crushing, thereby enhancing the crushing effect of the auger faucet and improving the working efficiency of the dredger, especially when encountering blocky mud and sand, it can be fully cut and crushed to avoid the mud suction pipe being blocked by large particles of mud and sand.

[0033] Specifically, the conical frame 3 in this embodiment is composed of a coupling head 30, six supporting ribs 31 and a reinforcing ring 32. The front end of the coupling head 30 also has a drill bit 9 to improve the earth-breaking performance. The coupling head 30 is installed at the front end of the drive shaft 2, and the front ends of the six supporting ribs 31 are close to each other and connected to the coupling head 30, and the six supporting ribs 31 and the coupling head 30 are an integrally formed structure, so that the structure is more solid and has higher strength; the reinforcing ring 32 has a diameter larger than the coupling head 30 and is connected to the rear ends of the six supporting ribs 31. The reinforcing ring 32 can also be made into an integral structure with the six supporting ribs 31, but the blade can only be replaced as a whole after being worn, which is not conducive to cost. Therefore, in this embodiment, the reinforcing ring 32 and the six supporting ribs 31 are designed to be detachably assembled and fixed, that is, the reinforcing ring 32 is fixed to the six supporting ribs 31 by some fixing screws 33, which can also facilitate the disassembly and replacement of worn blades. It is worth mentioning that the conical frame 3 of this embodiment adopts a combined structure of a connecting head 30, six supporting ribs 31 and a reinforcing ring 32. On the one hand, the mud can flow smoothly to the mud suction pipe 7 during the rotation and crushing of mud and sand, thereby ensuring the efficiency of mud suction. On the other hand, the structure of the reinforcing ring 32 can enhance the strength of the overall conical frame 3, so that after the support ribs 31 fix the blade, the overall consistency of the rotary strangulation is higher and the crushing performance is better.

[0034] Specifically, in this embodiment, two separate blades 4 and one integrated blade 5 are mounted on each support rib 31, and the integrated blade 5 is located between the two separate blades 4. This can form a staggered arrangement effect, so that the strangulation force can be effectively dispersed when the auger faucet is rotated and crushed, thereby enhancing the crushing effect of the auger faucet.

[0035] More specifically, the separate blade 4 in this embodiment is composed of a first block 40 and two spaced and parallel cutting blades 41 formed on the first block 40. The first block 40 is clamped on the support rib 31 and fixed by a fastening screw 42 to ensure firmness during operation. At the same time, the integrated blade 5 in this embodiment is composed of a second block 50 and a V-shaped blade 51 formed on the second block 50. The second block 50 is clamped on the support rib 31 and fixed by a fastening screw 42 to ensure firmness during operation. When the cutting blade 41 and the V-shaped blade 51 are damaged due to long-term use or collision with hard objects, the fastening screw 42 can be loosened to slide them backward along the support rib 31 for replacement, which is more convenient and cost-saving.

[0036] In order to assist the auger faucet structure in crushing, the present embodiment further provides an auxiliary crushing mechanism 8 on both sides of the installation body 1. The auxiliary crushing mechanism 8 specifically consists of a connecting rod 80, a hydraulic rod 81, a waterproof motor 82, a spiral auger rod 83 and other components. The connecting rod 80 is rotatably hinged at the rear end of the side wall of the installation body 1 through a first hinge seat 84, one end of the hydraulic rod 81 is rotatably hinged at the front position of the side wall of the installation body 1 through a second hinge seat 85, and the other end of the hydraulic rod 81 is rotatably hinged on the connecting rod 80. The waterproof motor 82 is installed at the front end of the connecting rod 80, and the spiral auger rod 83 is installed on the output shaft of the waterproof motor 82. The extension and retraction of the hydraulic rod 81 can drive the connecting rod 80 to rotate, thereby driving the spiral auger rod 83 to swing to adjust the angle range of crushing. In this way, by installing the auxiliary crushing mechanism 8 on both sides of the main body 1, the spiral auger rod 83 is driven by the waterproof motor 82 to rotate, which can assist the auger head structure in crushing work, pierce and loosen the surrounding mud and sand, and guide and gather it to the middle, etc., thereby improving the crushing efficiency and the mud suction effect; at the same time, the drilling angle of the spiral auger rod 83 can be adjusted by relying on the extension and retraction of the hydraulic rod 81, so as to facilitate the adjustment of the crushing range according to different underwater environments and mud conditions.
