AI Technical Summary
Existing slurry pumps are prone to impeller jamming and pipeline blockage when the discharge capacity is small due to foreign objects such as stones and branches mixed in the slurry entering the pump cavity. High-density particles such as sand and gravel settle during transportation, causing pipeline blockage and inner wall wear, affecting the continuity of operation and increasing the equipment failure rate.
A slurry pump is used to connect to the slurry cutter frame. The slurry cutter body is rotated by a combination of a first fixed ring, a second fixed ring, a first gear, a turntable, a rotating rod, the cutter body, a gear ring, a second gear, and a drive motor. This pre-treats foreign objects such as stones and branches in the slurry, reduces pump cavity blockage, and adjusts the distance between the slurry pump and the cutter body through a positioning frame and a positioning plate to adapt to different media crushing conditions.
It effectively reduces the problem of foreign objects entering the pump chamber and clogging the pipeline in slurry pumps, improves the continuity of operation, reduces the equipment failure rate, and adapts to the sludge dredging needs of different media.

Description
Technical Field
[0001] This application relates to slurry pumps, and more particularly to a slurry pump dredging connection cutter frame. Background Technology
[0002] River dredging is a crucial step in maintaining water resource ecology and ensuring the safe operation of water conservancy projects. Its core task is to remove the mixture of silt, sand, gravel, and debris deposited on the riverbed using mechanical equipment to restore the river's flood control capacity and improve water quality. In this process, the slurry pump, as a key piece of equipment for transporting high-concentration solid-liquid mixtures, directly determines the dredging efficiency and operating costs.
[0003] In the existing technology, the application mode of traditional slurry pumps has revealed many technical bottlenecks in long-term practice. For example, the riverbed environment is complex, and foreign objects such as stones and branches mixed in the slurry can easily enter the pump chamber when the pump discharge is small, causing impeller jamming and pipeline blockage. High-density particles such as sand and gravel are prone to settling due to gravity during transportation, causing pipeline blockage and inner wall wear. After working for a period of time, the machine needs to be stopped for cleaning, which not only seriously affects the continuity of operation, but also increases the equipment failure rate. Utility Model Content
[0004] The purpose of this application is to provide a slurry pump dredging connection cutter frame, which solves the problem that when the slurry pump has a small discharge capacity, foreign objects such as stones and branches mixed in the slurry can easily enter the pump chamber, causing impeller jamming and pipeline blockage. High-density particles such as sand and gravel are prone to settling due to gravity during transportation, causing pipeline blockage and inner wall wear. As a result, the slurry pump needs to be stopped for cleaning after working for a period of time, which not only seriously affects the continuity of operation, but also increases the equipment failure rate.
[0005] The slurry pump dredging connection reamer frame provided in this application adopts the following technical solution: it includes a first frame, a slurry pump body, and a second frame. The second frame is located at one end of the first frame and is fixedly connected to the first frame. Two positioning frames are fixedly connected inside the first frame. Two positioning plates are fixedly connected to the outside of the slurry pump body. Threaded holes are opened inside the positioning frames and the positioning plates, and bolts are threadedly connected to them. A side plate is fixedly connected inside the first frame. A connecting plate is fixedly connected to the outside of the slurry pump body. Threaded holes are opened inside the side plate and the connecting plate, and bolts are threadedly connected to them.

The number of turntables is equal to the number of first gears. A rotating rod is fixedly connected between the turntables and the first gears. Several reamer bodies are fixedly connected to the outside of the rotating rod.
[0006] By adopting the above technical solution, the first gear, after rotating, can cause the rotating rod to drive the reamer body to rotate. Then, the reamer body can pre-treat solid foreign objects such as stones and branches in the silt, reducing the blockage inside the pump chamber. This solves the problem that when the slurry pump has a small discharge capacity, foreign objects such as stones and branches mixed in the slurry can easily enter the pump chamber, causing impeller jamming and pipeline blockage. High-density particles such as sand and gravel are prone to settling due to gravity during transportation, causing pipeline blockage and inner wall wear. This results in the slurry pump needing to be stopped for cleaning after working for a period of time, which not only seriously affects the continuity of operation, but also increases the equipment failure rate.

Threaded holes are opened inside the fixing block and inside the second frame. A first bolt is threadedly connected inside the threaded hole of the fixing block.
[0010] By adopting the above technical solution, the first bolt can fix the fixing block to the frame body, thereby limiting the position of the first fixing ring through the fixing rod.
[0011] Preferably, four fixing plates are fixedly connected to the outer side of the second fixing ring. Threaded holes are provided inside the fixing plates and inside the second frame. Second bolts are threadedly connected inside the threaded holes of the fixing plates.
[0012] By adopting the above technical solution, the second bolt can fix the fixing plate to the frame body, thereby limiting the position of the second fixing ring.

[0017] Preferably, the output shaft of the drive motor passes through the mounting plate and is fixedly connected to the second gear, the second gear meshes with a gear ring, and the gear ring meshes with the first gear;
[0018] By adopting the above technical solution, the drive motor causes the second gear to rotate, thereby causing the gear ring to rotate, and the gear ring, after rotating, can cause the first gear to rotate.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. This slurry pump dredging connection cutter frame, through the arrangement of a first fixed ring, a second fixed ring, a first gear, a turntable, a rotating rod, a cutter body, a gear ring, a second gear, and a drive motor, allows the device to operate by simply starting the drive motor, which in turn causes the second gear to rotate with the gear ring. The rotation of the gear ring causes the first gear to rotate, which in turn causes the rotating rod to rotate the cutter body. The cutter body then pre-treats solid foreign objects such as stones and branches in the slurry, reducing blockage inside the pump chamber. This solves the problem that when the slurry pump has a small discharge capacity, foreign objects such as stones and branches mixed in the slurry easily enter the pump chamber, causing impeller jamming and pipe blockage. High-density particles such as sand and gravel are also prone to settling due to gravity during transport, causing pipe blockage and inner wall wear. This necessitates stopping the slurry pump for cleaning after a period of operation, severely affecting operational continuity and increasing equipment failure rates.
[0021] 2. The slurry pump is connected to the cutter frame for dredging. It is set up with a first frame, a positioning frame, a positioning plate, a side plate and a connecting plate. During use, the positioning plate can slide on the outside of the positioning frame, so that the slurry pump body can move inside the first frame. This adjusts the distance between the slurry pump and the cutter body, so that the suction position of the slurry pump body can adapt to the crushing conditions of different media such as silt, sand and gravel and hard soil.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0030] Example 1: Slurry pump dredging connection cutter frame, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a first frame 1, a slurry pump body 2, and a second frame 8. The second frame 8 has a first fixing ring 9 and a second fixing ring 13 inside. Several first gears 16 are rotatably connected to one side surface of the first fixing ring 9. Several turntables 17 are rotatably connected to one side surface of the second fixing ring 13, with the number of turntables 17 equal to the number of first gears 16. Rotating rods 18 are fixedly connected between the turntables 17 and the first gears 16. Several reamer bodies 19 are fixedly connected to the outer side of the rotating rods 18. Four fixing rods 10 are fixedly connected to the outer side of the first fixing ring 9, with the fixing rods 10 located away from the first fixing ring 9. One end of the first fixing ring 9 is fixedly connected to a fixing block 11. Threaded holes are provided inside both the fixing block 11 and the second frame 8. A first bolt 12 is threaded into the threaded hole inside the fixing block 11. Four fixing plates 14 are fixedly connected to the outer side of the second fixing ring 13. Threaded holes are provided inside both the fixing plates 14 and the second frame 8. Second bolts 15 are threaded into the threaded holes inside the fixing plates 14. An annular groove is provided on one side surface of the first fixing ring 9, and a toothed ring 20 is rotatably connected thereto. Gear teeth are fixedly connected to both the inner and outer sides of the toothed ring 20. A mounting plate 21 is fixedly connected to the outer side of the first fixing ring 9. One side of the mounting plate 21 is rotatably connected to a second gear 22, and the side of the mounting plate 21 away from the second gear 22 is fixedly connected to a drive motor 23. The output shaft of the drive motor 23 passes through the mounting plate 21 and is fixedly connected to the second gear 22. The second gear 22 meshes with a gear ring 20, and the gear ring 20 meshes with a first gear 16. Through the arrangement of the first fixed ring 9, the second fixed ring 13, the first gear 16, the turntable 17, the rotating rod 18, the reamer body 19, the gear ring 20, the second gear 22, and the drive motor 23, the device can be used by simply starting the drive motor 23 to make the second gear 22 rotate with the gear ring 20. When the ring 20 rotates, it causes the first gear 16 to rotate. After the first gear 16 rotates, it causes the rotating rod 18 to drive the reamer body 19 to rotate. Then the reamer body 19 can pre-treat solid foreign objects such as stones and branches in the silt, reducing the blockage inside the pump chamber. This solves the problem that when the slurry pump has a small discharge capacity, foreign objects such as stones and branches mixed in the slurry can easily enter the pump chamber, causing impeller jamming and pipeline blockage. High-density particles such as sand and gravel are prone to settling due to gravity during transportation, causing pipeline blockage and inner wall wear. This causes the slurry pump to need to be stopped for cleaning after working for a period of time, which not only seriously affects the continuity of operation, but also increases the equipment failure rate.
[0031] Example 2: Slurry pump dredging connection cutter frame, refer to Figure 1 , Figure 2The second frame 8 is located at one end of the first frame 1 and is fixedly connected to the first frame 1. Two positioning frames 3 are fixedly connected inside the first frame 1, and two positioning plates 4 are fixedly connected to the outside of the slurry pump body 2. Threaded holes are opened inside the positioning frames 3 and the positioning plates 4, and bolts are threadedly connected to them. A side plate 5 is fixedly connected inside the first frame 1, and a connecting plate 6 is fixedly connected to the outside of the slurry pump body 2. Threaded holes are opened inside the side plate 5 and the connecting plate 6, and bolts are threadedly connected to them. Several lifting rings 7 are fixedly connected to the end of the first frame 1 away from the second frame 8. The lifting rings 7 are fixedly connected to the first frame 1 by welding. Through the arrangement of the first frame 1, positioning frames 3, positioning plates 4, side plates 5, and connecting plates 6, the positioning plates 4 can slide outside the positioning frames 3 during use, thereby allowing the slurry pump body 2 to move inside the first frame 1. This adjusts the distance between the slurry pump and the cutter body 19, so that the suction port position of the slurry pump body 2 can adapt to the crushing conditions of different media such as silt, sand, gravel, and hard soil.
[0032] The implementation principle of this application embodiment is as follows: In use, the first fixing ring 9 and the second fixing ring 13 are placed inside the second frame 8, with the fixing block 11 tightly against the inner wall of the second frame 8. Then, the first bolt 12 is passed through the internal threaded hole of the second frame 8 and the internal threaded hole of the fixing block 11. A nut is then threaded onto the outer side of the first bolt 12 to limit the first bolt 12, thereby connecting the fixing block 11 to the second frame 8. The remaining fixing blocks 11 are then fixed in the same way. Next, the second bolt 15 is passed through the second frame 8 and the fixing plate 14, with a nut threaded onto the outer side of the second bolt 15 to limit the second bolt 15, thereby connecting the fixing plate 14 to the second frame 8. Then, the slurry pump body 2 is connected. During connection, the positioning plate 4 is placed on top of the positioning frame 3, and then the slurry pump body 2 is pushed to move the positioning plate 4 above the positioning frame 3, thereby adjusting the slurry pump body 2 and the reamer body 19. After adjusting the spacing between them, the bolts are passed through the positioning frame 3 and the positioning plate 4, and the bolt threads are connected between the positioning plate 4 and the positioning frame 3 to fix the positioning frame 3 and the positioning plate 4. Then, the bolts are passed through the side plate 5 and the connecting plate 6, and the bolt threads are connected between the side plate 5 and the connecting plate 6 to fix the side plate 5 and the connecting plate 6, thereby fixing the slurry pump body 2. Then, an external hoisting device is used to hoist the hook of the external hoisting device into the inside of the lifting ring 7 to transport the device. After that, the device is placed in the location where sludge needs to be dredged and dredging can be carried out. During dredging, the slurry pump body 2 and the drive motor 23 are started. After the drive motor 23 starts, the second gear 22 rotates. After the second gear 22 rotates, the gear ring 20 rotates. After the gear ring 20 rotates, the first gear 16 rotates. After the first gear 16 rotates, the rotating rod 18 drives the reamer body 19 to rotate. Then, the reamer body 19 crushes foreign objects such as stones or branches. After the slurry pump body 2 starts, it can generate suction to dredge the sludge.
