Description

Technical Field

[0001] This application relates to the technical field of dredger bucket wheels, and in particular to a wear-resistant bucket tooth bucket wheel type dredger bucket wheel. Background Technology

[0002] The bucket wheel of a wear-resistant bucket wheel dredger is a device specifically designed for dredging and transporting mud and sand. The bucket wheel is equipped with multiple bucket teeth, which are typically made of wear-resistant materials to resist wear and tear generated during contact with hard soil or rock during dredging.

[0003] The core component of a bucket wheel dredger is a large, circular bucket wheel equipped with numerous bucket teeth or shovels. As the bucket wheel rotates, these teeth cut into the sediment in the riverbed or seabed, scooping it up and loading it into the bucket troughs. With continued rotation, the sediment-laden teeth are brought to the top of the bucket wheel, where the sediment is unloaded from the teeth onto a conveyor belt or falls directly into the dredging hopper, thus completing the operation.

[0004] However, in actual use, the inside of the bucket wheel and the feed inlet may become clogged, especially when dealing with highly viscous or moist materials. Clogged feed inlets can affect the normal operation of the bucket wheel dredger, reduce dredging efficiency, and may even cause the equipment to stop. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a wear-resistant bucket tooth bucket wheel for dredgers.

[0006] This application provides a wear-resistant bucket tooth bucket wheel type dredger bucket wheel, which adopts the following technical solution: A wear-resistant bucket tooth bucket wheel type dredger bucket wheel includes a hollow shaft, two external pipes are provided on both sides of the hollow shaft, a mud suction port is opened on the upper side of the hollow shaft, two circular shafts are rotatably fitted on the hollow shaft, and multiple bucket wheels are fixedly connected to the adjacent sides of the two circular shafts, and multiple bucket teeth are fixedly connected to one side of the inner wall of the multiple bucket wheels;

[0007] Each of the bucket wheels has a hollow trough plate fixedly connected to one side, and a scraper is slidably fitted on the inner wall of each of the hollow trough plates. Multiple springs are provided between the scrapers and the hollow trough plates. Two inclined plates that cooperate with the scrapers are fixedly connected to the inner wall of the mud extraction port. A vibration assembly that cooperates with the bucket wheels is provided on one side of the hollow shaft.

[0008] Optionally, the vibration assembly includes an extension block fixedly connected to one side of the hollow shaft, a reset rod rotatably fitted on the upper side of the extension block, a striking rod fixedly connected to the upper side of the reset rod, an operating groove formed at the bottom of the reset rod, and a high-strength torsion spring disposed inside the operating groove and fixedly connected to the extension block.

[0012] Optionally, a sealed bearing is rotatably fitted on the lower side of the reset rod, and the lower side of the sealed bearing is fixedly connected to the extension block.

[0013] Optionally, the outer surfaces of the bucket teeth and the plurality of bucket wheels are all treated with a tungsten carbide coating.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. This utility model, by setting up a mud extraction port, an empty groove plate, a scraper, a spring, and an inclined plate, can achieve the following: when the scraper moves to the upper side of the mud extraction port, multiple springs simultaneously squeeze the scraper, causing the scraper to immerse itself in the mud extraction port, thereby scraping away any sludge that may be present inside the mud extraction port and reducing the possibility of blockage.

[0016] 2. This utility model, by setting a vibration component, enables the bucket wheel to contact the striking rod when it rotates. The bucket wheel will push the striking rod accordingly. When it is pushed to a certain extent, the striking rod separates from the corresponding bucket wheel. Through the elastic force of the high-strength torsion spring, the striking rod is instantly reset. During the reset process, it will strike another bucket wheel, causing it to vibrate. This can reduce the problem of soil adhering to the bucket wheel. The vibration helps to break the adhesion between the soil and the surface of the bucket wheel, making the soil easier to fall off.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a wear-resistant bucket wheel type dredger bucket wheel. For example... Figure 1 As shown, it includes a hollow shaft 1, with two external pipes 2 on both sides of the hollow shaft 1. A mud extraction port 3 is opened on the upper side of the hollow shaft 1. Two circular shafts 4 are rotatably fitted on the hollow shaft 1. Multiple bucket wheels 5 are fixedly connected to the adjacent side of the two circular shafts 4. Multiple bucket teeth 6 are fixedly connected to one side of the inner wall of the multiple bucket wheels 5.

[0024] Please see Figure 1 and Figure 2 A corrosion-resistant sprocket 12 is fixedly connected to one side of one of the two circular shafts 4. The corrosion-resistant sprocket 12 is welded to the circular shaft 4. The corrosion-resistant sprocket 12 can be connected to an external drive device via a chain.

[0025] Please see Figure 1 Multiple bucket teeth 6 and multiple bucket wheels 5 are fixed together by bolts. By fixing them with the corresponding bolts, 6 can be disassembled and replaced periodically.

[0026] Please see Figure 1 The outer surfaces of the bucket teeth 6 and multiple bucket wheels 5 are all treated with tungsten carbide coating. Tungsten carbide is a very hard material with high wear resistance. Applying tungsten carbide coating can significantly improve the wear resistance of the bucket wheel 5 surface, reduce the wear of the bucket wheel 5 during the digging process, and extend the service life of the bucket wheel 5 due to the improved wear resistance, thereby reducing the frequency of bucket wheel 5 replacement and related maintenance costs.

[0027] A hollow trough plate 7 is fixedly connected to one side of each of the multiple bucket wheels 5. A scraper 8 is slidably fitted on the inner wall of each of the multiple hollow trough plates 7. Multiple springs 9 are provided between the multiple scrapers 8 and the hollow trough plates 7. Two inclined plates 10 that cooperate with the scrapers 8 are fixedly connected to the inner wall of the mud extraction port 3. A vibration assembly 11 that cooperates with the multiple bucket wheels 5 is provided on one side of the hollow shaft 1.

[0028] Please see Figure 2Both sides of the scraper 8 are fitted with rotating wheels 14, which are engaged with the two inclined plates 10. After the rotating wheels 14 come into contact with the hollow shaft 1, the friction between them is reduced. When the rotating wheels 14 come into contact with the inclined plates 10, the guide of the scraper 8 is increased and the lubrication effect is enhanced.

[0029] Please see Figure 1 and Figure 3 The vibration assembly 11 includes an extension block 111 fixedly connected to one side of the hollow shaft 1, a reset rod 112 rotatably fitted on the upper side of the extension block 111, a striking rod 113 fixedly connected to the upper side of the reset rod 112, an operating groove 114 opened at the bottom of the reset rod 112, and a high-strength torsion spring 115 disposed inside the operating groove 114 and fixedly connected to the extension block 111. When the circular shaft 4 moves, the striking rod 113 changes position, and the high-strength torsion spring 115 is compressed. When the operating groove 114 separates from the bucket wheel 5, the high-strength torsion spring 115 will drive the reset rod 112 and the striking rod 113 to reset instantly, so as to strike the next bucket wheel 5. This cycle helps to break the adhesion between the soil and the surface of the bucket wheel 5, making it easier for the soil to fall off.

[0030] Please see Figure 3 The lower side of the reset rod 112 is rotatably fitted with a sealed bearing 15. The lower side of the sealed bearing 15 is fixedly connected to the extension block 111. The sealed bearing 15 can protect the high-strength torsion spring 115 inside the reset rod 112 and reduce the impact of water contact on its performance.

[0031] The implementation principle of a wear-resistant bucket wheel dredger according to an embodiment of this application is as follows: In use, firstly, it is connected to the corresponding dredging pump through two external pipes 2, the hollow shaft 1 is immersed in water, and then connected to the corresponding drive through the circular shaft 4, so that multiple bucket wheels 5 are rotated to dig the mud and sand at the bottom of the ground into the interior of the bucket wheel 5. By rotating, the dredged mud and sand are turned to the upper side of the dredging port 3, and negative pressure is generated in the dredging port 3 to suck out the mud and sand, thus performing the sand dredging operation.

[0032] During the sand pumping process, when the scraper 8 moves to the upper side of the mud pumping port 3, multiple springs 9 simultaneously squeeze the scraper 8, causing the scraper 8 to enter the mud pumping port 3. This scrapes away any sludge that may be present inside the mud pumping port 3, reducing the possibility of blockage and ensuring that the material enters the bucket wheel 5 smoothly. The inclined plate 10 guides the scraper 8, allowing it to retract into the interior of the empty trough plate 7 after it leaves the mud pumping port 3.

[0033] As multiple bucket wheels 5 rotate, they come into contact with the striking rod 113. The bucket wheels 5 push the striking rod 113 accordingly. When pushed to a certain extent, the striking rod 113 separates from the corresponding bucket wheel 5. Through the elastic force of the high-strength torsion spring 115, the striking rod 113 is instantly reset. During the reset process, it strikes another bucket wheel 5, causing the bucket wheel 5 to vibrate. This can reduce the problem of soil adhering to the bucket wheel 5. The vibration helps to break the adhesion between the soil and the surface of the bucket wheel 5, making it easier for the soil to fall off.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
