Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and in particular to a vibratory in-situ decomposition and loosening device for silt inside river channels. Background Technology

[0002] Rivers, as natural waterways, not only serve the vital function of supplying water resources but are also an important part of the ecological environment. However, with the acceleration of urbanization and the increase in human activities, the problem of silt accumulation in river channels has become increasingly serious. This silt not only affects the navigation capacity of the river channels but also may pollute the water quality, thereby threatening the surrounding ecological environment and human health.

[0003] Traditional river dredging methods mostly employ excavators or dredging vessels to remove the silt, which is then processed. However, this method has several drawbacks. First, the dredging process easily damages the riverbed and banks, leading to soil erosion and ecological degradation. Second, the dredged silt needs to be transported to designated locations for treatment, increasing transportation costs and potentially causing secondary pollution along the way. Finally, traditional dredging methods are ineffective at handling hard soil within the silt, often requiring additional crushing equipment, further increasing costs.

[0004] To overcome the shortcomings of traditional dredging methods, people have begun to explore more efficient and environmentally friendly methods for treating river silt. Among them, vibratory silt treatment technology has attracted much attention due to its advantages such as high efficiency, energy saving, and environmental friendliness. Vibratory silt treatment technology breaks down the structure of silt through vibration, making it loose and easier for subsequent treatment or natural degradation. However, most existing vibratory silt treatment equipment suffers from problems such as complex operation, high cost, and limited applicability, making it difficult to meet practical applications. Summary of the Invention

[0010] The present invention is further configured such that the first decomposition plate and the second decomposition plate are alternately distributed, and the surfaces of the first decomposition plate and the second decomposition plate are provided with a number of arc-shaped stripes, which are arranged alternately.

[0011] The invention is further configured such that the turntable, through the curvature change inside the groove, pulls or pushes the connecting bolt, thereby driving the first decomposition plate and the second decomposition plate to swing left and right in a cycle through the movable plate and the fixed rod, generating vibration to decompose the sludge.

[0012] The present invention is further configured such that the excavation mechanism is fixedly connected to a second box, which includes a first box. A connecting pipe is provided at one end of the second box away from the first box. The connecting pipe is a flexible hose. A material extraction pipe is provided at the other end of the connecting pipe. A drill bit is rotatably connected to the end of the material extraction pipe away from the connecting pipe. A drive motor is provided at the top of the connecting pipe. The output end of the drive motor extends through the inside of the material extraction pipe and is fixedly connected to a transmission rod. One end of the transmission rod is fixedly connected to the drill bit.

[0013] The present invention is further configured such that connecting arms are hinged to both sides of the second box body, the other end of the connecting arms is hinged to the material picking tube, a fixed seat is fixedly connected to the top of the second box body, a telescopic rod is hinged inside the fixed seat, a fixed seat is hinged to the output end of the telescopic rod, and the fixed seat is fixedly connected to the outer wall of the material picking tube.

[0015] The beneficial effects of the vibratory in-situ decomposition and loosening device for silt inside river channels of the present invention are as follows:

[0016] 1. The drive motor drives the rotation of transmission discs one and two, which in turn drives the turntable and its curved groove to rotate. The cooperation between the curved groove and the connecting bolt allows the decomposition plates one and two to swing left and right in a cycle inside the housing one. The vibration generated by this cyclic swing can efficiently decompose and loosen the silt inside the river channel, improving the efficiency of silt treatment.

[0017] 2. The decomposition mechanism of the present invention is ingeniously designed. By utilizing the rotation of the turntable and the curvature change of the groove, the cyclic swing of decomposition plate one and decomposition plate two is realized through a simple mechanical structure. It does not require a complex transmission system and additional energy input, thus reducing the manufacturing and operating costs of the equipment.

[0018] 3. The excavation mechanism integrates sludge excavation and transportation. A three-drive motor rotates the drill bit, drawing the sludge into the intake pipe. Then, a conveyor belt and feeding plates transport the sludge to the inner chamber for further processing. This design not only simplifies the operation process but also improves the continuity and efficiency of sludge treatment.

[0019] 4. The telescopic rod in the excavation mechanism can push the feed pipe to adjust the position of the drill bit in the water, making the equipment suitable for treating river silt at different depths and locations.

[0034] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 5A vibratory in-situ decomposition and loosening device for riverbed silt includes a main body 1. A decomposition mechanism 12 is installed on the top of the main body 1. An extraction component 14 is installed on one side of the decomposition mechanism 12, and a digging mechanism 13 is installed on the other side of the decomposition mechanism 12. The decomposition mechanism 12 includes a box body 121. A docking groove 1211 is symmetrically opened on the top and bottom of the inner side of the box body 121. Side boxes 122 are installed on both sides of the outer wall of the box body 121. A limit frame 1221 is installed on the side of the side box 122 away from the box body 121. A turntable 125 is rotatably connected inside the limit frame 1221. A driving rod 124 is fixedly connected at the center of the top and bottom of the turntable 125. A curved groove 1251 is opened inside the turntable 125. A docking groove 1211 is symmetrically opened on the top and bottom of the inner side of the box body 121. Decomposition plates are slidably connected inside the docking groove 1211. The first box 126 and the second box 127 are separated by partitions 1212 at the top and bottom of the inner side of the first box 121 near the docking groove 1211. The partitions 1212 are provided with several limiting grooves 1213 near the docking groove 1211. The docking groove 1211 and the limiting grooves 1213 are connected. The limiting grooves 1213 are slidably connected with fixed rods 128. The fixed rods 128 are fixedly connected to the first box 126 and the second box 127 respectively. One end of the fixed rods 128 extends into the side box 122 and is fixedly connected to a movable plate 1281. The side box 122 is provided with a spring 1222 at one end connected to the movable plate 1281. The movable plate 1281 is provided with a connecting bolt 129 near the turntable 125. One end of the connecting bolt 129 extends into the curved groove 1251 and is slidably connected to the inner wall of the curved groove 1251.

[0035] By adopting the above technical solution, after the drive motor 123 starts, it drives the transmission disc 1215 to start rotating. This rotation is transmitted to the transmission disc 1217 via the transmission belt 1216, causing it to rotate as well. The transmission disc 1217 drives the turntable 125 to rotate via the rod 124. The rotation of the turntable 125 causes the curved groove 1251 to move accordingly, and the change in curvature of the curved groove 1251 pulls or pushes the connecting bolt 129. As the connecting bolt 129 moves, it drives the decomposition plate 126 and the decomposition plate 127 to swing left and right in a cycle through the linkage of the movable plate 1281 and the fixed rod 128. This swinging generates vibration, effectively decomposing the sludge. The successfully decomposed sludge is then removed by the extraction assembly 14.

[0036] A second transmission disc 1217 is rotatably connected to the top of the inner side of the side box 122. One end of the driving rod 124 is fixedly connected to the second transmission disc 1217. A partition 1214 is fixedly connected to the inner layer 1212 of the first box 121 near the top, above the fixed rod 128. A first transmission disc 1215 is rotatably connected to the center of the partition 1214. A transmission belt 1216 connected to the second transmission disc 1217 is provided on the surface of the first transmission disc 1215. A drive motor is provided at the top of the first box 121 near the first transmission disc 1215. 123, the output end of the drive motor 123 passes through the housing 121 and is fixedly connected to the transmission plate 1215. The decomposition plate 126 and the decomposition plate 2 127 are alternately distributed. The surfaces of the decomposition plate 126 and the decomposition plate 2 127 are provided with several arc-shaped stripes, which are arranged in an alternating manner. The turntable 125 pulls or pushes the connecting bolt 129 through the curvature change inside the groove 1251, and then drives the decomposition plate 126 and the decomposition plate 2 127 to swing left and right in a cycle through the movable plate 1281 and the fixed rod 128, generating vibration to decompose the sludge.

[0037] By adopting the above technical solution, the drive motor 123 drives the transmission disc 1215 and the transmission disc 1217 to rotate, and then the moving rod 124 drives the turntable 125 to rotate, thereby pulling the movable plate 1281 back and forth through the connecting bolt 129. The fixed rod 128 of the movable plate 1281 drives the decomposition plate 126 and the decomposition plate 127 to move back and forth quickly. The rapid reciprocating motion generates vibration to decompose the sludge.

[0038] The excavation mechanism 13 is fixedly connected to a second housing 131, which includes a first housing 121. A connecting pipe 133 (a flexible hose) is provided at one end of the second housing 131 away from the first housing 121. A material extraction pipe 134 is provided at the other end of the connecting pipe 133. A drill bit 1341 is rotatably connected to the end of the material extraction pipe 134 away from the connecting pipe 133. A third drive motor 1343 is provided at the top of the connecting pipe 133. The output end of the third drive motor 1343 extends into the material extraction pipe 134 and is fixedly connected to a transmission rod 1342. One end of the transmission rod 1342 is fixedly connected to the drill bit 1341. Connecting arms 135 are hinged to both sides of the second housing 131. The other end of each connecting arm 135 is connected to the material extraction pipe. 134 is hinged. The top of the second box 131 is fixedly connected to the first fixed seat 136. The first fixed seat 136 is hinged to the telescopic rod 1361. The output end of the telescopic rod 1361 is hinged to the second fixed seat 1362. The second fixed seat 1362 is fixedly connected to the outer wall of the material picking tube 134. The inside of the second box 131 is rotatably connected to the shaft 132 near both ends. The surface of the shaft 132 is provided with a conveyor belt 1321. The outer surface of the conveyor belt 1321 is evenly provided with several feeding plates 1322. The outer wall of the second box 131 is provided with a second drive motor 1323 near the shaft 132. The output end of the second drive motor 1323 passes through the second box 131 and is fixedly connected to the shaft 132.

[0039] By adopting the above technical solution, the position of the feed pipe 134 is adjusted using the telescopic rod 1361, allowing the drill bit 1341 to be aligned with the target in the water. Subsequently, the drive motor 1343 drives the drill bit 1341 to rotate via the drive rod 1242, drawing silt into the feed pipe 134. After entering the feed pipe 134, the silt falls onto the conveyor belt 1321 via the connecting pipe 133. At this time, the drive motor 1323 drives the conveyor belt 1321 to start operating via the rotating shaft 132, which in turn drives the feeding plate 1322 to move. The movement of the feeding plate 1322 causes the silt to be transported into the housing 121.

Inside the housing 121, near the top and bottom, partitions 1212 are provided. Inside the partitions 1212, near the docking groove 1211, several limiting grooves 1213 are provided. These limiting grooves 1213 communicate with the docking groove 1211, and fixing rods 128 are slidably connected inside each limiting groove 1213. These fixing rods 128 are respectively connected to the disintegration plates. 126. The disassembly plate 127 is fixedly connected. One end of the fixing rod 128 extends into the side box 122.

The surface of the transmission disk 1215 is connected to the transmission disk 2 1217 through the transmission belt 1216.

[0044] The excavation mechanism 13 includes a second housing 131 fixedly connected to a first housing 121. Inside the second housing 131, near both ends, are rotating shafts 132. A conveyor belt 1321 is mounted on the surface of each shaft 132, and several feeding plates 1322 are evenly distributed on the outer surface of the conveyor belt 1321. A second drive motor 1323 is mounted on the outer wall of the second housing 131 near the shafts 132. The output end of the second drive motor 1323 passes through the second housing 131 and is fixedly connected to the shafts 132. A connecting pipe 133, which is a flexible hose, is mounted at one end of the second housing 131 away from the first housing 121. A material-collecting pipe 134 is mounted at the other end of the connecting pipe 133. Connecting arms 1 are hinged to both sides of the second housing 131. 35. The other end of the connecting arm 135 is hinged to the material taking tube 134. The top of the box body 131 is fixedly connected to the fixed seat 136. The telescopic rod 1361 is hinged inside the fixed seat 136. The output end of the telescopic rod 1361 is hinged to the fixed seat 2 1362. The fixed seat 2 1362 is fixedly connected to the outer wall of the material taking tube 134. The end of the material taking tube 134 away from the connecting tube 133 is rotatably connected to the drill bit 1341. The top of the connecting tube 133 is fixedly connected to the drive motor 3 1343. The output end of the drive motor 3 1343 passes through the inside of the material taking tube 134. The output end located inside the material taking tube 134 is fixedly connected to the driving rod 1242. One end of the driving rod 1242 is fixedly connected to the drill bit 1341.

[0045] During use, the position of the drill bit 1341 in the water is adjusted by pushing the material intake pipe 134 with the telescopic rod 1361. Then, the drive motor 1343 drives the drill bit 1341 to rotate through the drive rod 1242. The rotation of the drill bit 1341 brings the silt into the material intake pipe 134. The silt inside the material intake pipe 134 will fall onto the conveyor belt 1321 through the connecting pipe 133.

The curvature inside the curved groove 1251 pulls or pushes the connecting bolt 129. The movement of the connecting bolt 129 drives the decomposition plate 126 and decomposition plate 2 127 to swing left and right in a cycle through the movable plate 1281 and the fixed rod 128. The cyclic swing of decomposition plate 126 and decomposition plate 2 127 generates vibration. This cyclic swing generates vibration, which decomposes the sludge. The decomposed sludge is then pumped away by the extraction component 14.

[0047] The drive motor 123 drives the transmission disc to rotate, which in turn drives the turntable 125 and its curved groove 1251 to rotate. The curved groove 1251 cooperates with the connecting bolt 129 to make the decomposition plate 126 and the decomposition plate 127 circulate and swing within the housing 121, efficiently decomposing river silt. This decomposition mechanism 12 is ingeniously designed, reducing manufacturing and operating costs. The digging mechanism 13 drives the drill bit 1341 to rotate via the drive motor 1343, bringing the silt into the material intake pipe 134, and then transporting it to the housing 121 for processing via the conveyor belt 1321 and the feeding plate 1322. The telescopic rod 1361 can adjust the position of the drill bit 1341, and the connecting pipe 133 is a flexible hose, increasing the flexibility of the equipment.
