Second, silt blocks the pores of the riverbed, affecting the natural hydrological cycle, causing water pollution and damage to the ecosystem.

[0003] At present, the existing dredging equipment usually stirs the silt through a machine so that the silt can be stirred and dispersed, and then the silt is pushed and cleaned by water flow. However, when the stirring equipment comes into contact with the silt, it will be damaged by the solid mud lumps accumulated over the years, so that the dredging work is forced to stop, and a lot of time is needed to repair the equipment.

[0004] Therefore, it is urgent to improve the dredging device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a silt clearing device, in which a high-pressure pipe can spray water outward in the form of a high-pressure jet through a high-pressure pump. When a plurality of high-pressure pipes are rotated by a turntable, the sprayed water column can be in the shape of an inverted triangle water curtain, thereby simulating the effect of a drill bit to clean and disperse the silt in advance.

Detailed Description of the Embodiments

[0027] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0028] As Figures 1-5As shown in the figure, a dredging device provided in this embodiment includes an inner frame 4 and a turntable 5 rotatably arranged in the middle of the inner frame 4. It is characterized in that high-pressure pipes 6 are fixedly arranged at the four corners of the turntable 5. The turntable 5 can fix the positions of the high-pressure pipes 6. At the same time, it can also drive the high-pressure pipes 6 to rotate through the driving device. The high-pressure pipes 6 are rotatably connected to nozzles 8 through rotating hollow shafts 801. Among them, the nozzles 8 are communicated with the high-pressure pipes 6 through connecting hoses. A first driving motor 15 for angle adjustment is arranged on one side of the nozzle 8. The high-pressure pipes 6 can spray water outward in the form of high-pressure jets through a high-pressure pump. When multiple high-pressure pipes 6 rotate under the action of the turntable 5, the sprayed water columns can form an inverted triangular water curtain shape, so as to simulate the action of a drill bit to clean and disperse the silt first. The rotating hollow shaft 801 and the first driving motor 15 can adjust the orientation of the nozzle 8, so as to change the shape of the water curtain, and further, it is suitable for different usage requirements;

[0029] A fixing ring 13 is fixedly arranged in the middle of the turntable 5. An articulated hollow rod 10 is slidably connected to the inner side of the fixing ring 13. A stirring head 9 is fixedly arranged at the lower end of the articulated hollow rod 10. The articulated hollow rod 10 is fixedly limited to the fixing ring 13 through a limiting ball column 16. Through the fixing ring 13, the articulated hollow rod 10 can be connected to the turntable 5. Thus, when the turntable 5 rotates, the stirring head 9 can work to process relatively firm silt. The ejection mechanism includes: a fixed cylinder 17, an adjustment disc 20 and a top plate 19. The top plate 19 is used for the ejection support of the limiting ball column 16. The adjustment disc 20 is used for the ejection and reset of the top plate 19. The fixed cylinder 17 is used for the position fixation of the mechanism;

[0030] Among them, the fixed cylinder 17 is fixedly arranged at the lower end of the turntable 5, the adjusting disc 20 is rotatably arranged inside the fixed cylinder 17, a second driving motor 21 is fixedly installed at the bottom of the fixed cylinder 17, and the output end of the second driving motor 21 extends into the fixed cylinder 17 and is fixedly connected to the bottom of the adjusting disc 20. The connection between the fixed cylinder 17 and the turntable 5 can not only fix the position of the set mechanism, but also directly rotate the connecting hollow rod 10 and the stirring head 9 through the turntable 5. A number of adjusting grooves are formed in the adjusting disc 20, and adjusting columns 18 are slidably connected inside the adjusting grooves. The adjusting columns 18 are rotatably connected to the top plate 19 through a sliding plate. One end of the sliding plate is fixedly connected to the top plate 19, and the sliding plate is slidably connected to the fixed cylinder 17. When the second driving motor 21 drives the adjusting disc 20, the adjusting disc 20 can adjust the position of the adjusting columns 18 through the adjusting grooves. Thus, the adjusting columns 18 can jack up the top plate 19 or reset the position of the top plate 19. When the top plate 19 is jacked outwards, a strong jacking force can be applied to the limiting ball column 16 through the spring. Therefore, the connection effect between the limiting ball column 16 and the fixed ring 13 is strengthened. On the contrary, when the top plate 19 is reset, the spring is not in contact with the top plate 19, so that the connection effect between the limiting ball column 16 and the fixed ring 13 is reduced. Furthermore, it is convenient for the staff to disassemble the connecting hollow rod 10 and the fixed ring 13. At the same time, the diameter of the rear half of the limiting ball column 16 is larger than the limiting grooves formed on the connecting hollow rod 10 and the fixed ring 13. Therefore, the limiting ball column 16 can be prevented from sliding out.

[0031] To solve the water source problem of the high-pressure pipe 6:

[0032] Furthermore, as shown in the connection seat 2 - the inner frame 4 in the figure, limiting plates are fixedly arranged on both sides of the nozzle 8. The limiting plates are fixedly connected to the rotating hollow shaft 801. The first driving motor 15 is fixedly connected to one of the limiting plates. The limiting plates can fix the positions of the nozzle 8 and the first driving motor 15, preventing the nozzle 8 from separating from the rotating hollow shaft 801. A filter head 7 is fixedly arranged at the upper end of each high-pressure pipe 6. The filter head 7 is used for impurity filtration. When the high-pressure pipe 6 is immersed in water, the water flow can be sucked through the filter head 7. Thus, the high-pressure pipe 6 can obtain useful water source. At the same time, when the turntable 5 rotates at a high speed, some impurities attached to the filter head 7 can be thrown out to avoid hole blockage.

[0033] Such as Figures 1-3As shown in the figure, a driving motor 3 is fixedly arranged on the upper half of the inner frame 4. The output end of the driving motor 3 is fixedly connected to the turntable 5. The driving motor 3 can directly act on the turntable 5 to make the turntable 5 rotate. In this way, the above-mentioned effect can be achieved. The lower end of the inner frame 4 is threadedly engaged with a conical base 14. The connecting hollow rod 10 penetrates through the conical base 14 and extends to its outside. A spray pipe 11 is fixedly arranged on one side of the conical base 14, which can disassemble the bolts to separate the inner frame 4 from the conical base 14. Furthermore, the staff can directly observe the inside of the inner frame 4 and carry out maintenance and repair on it;

[0034] Among them, there is a certain gap between the connecting part of the conical base 14 and the connecting hollow rod 10, which allows the water carrying sediment to flow through. Thus, when the water enters the conical base 14, through the spray pipe 11 and the high-pressure pump, the muddy water is sprayed outwards. In this way, the muddy water in the cleaning part is separated from other impurities. An outer frame 1 is fixedly arranged on the outside of the inner frame 4. A connecting seat 2 is fixedly arranged at the upper end of the outer frame 1, which can connect the connecting seat 2 with external crane equipment. Furthermore, the river silt can be cleaned remotely on the shore.

[0035] As Figures 1-5 shown, the principle of the dredging device provided in this embodiment is as follows:

[0036] The high-pressure pipe 6 can spray water outwards in the form of high-pressure jet through the high-pressure pump. When multiple high-pressure pipes 6 rotate under the action of the turntable 5, the sprayed water column can form an inverted triangular water curtain shape to simulate the function of a drill bit and clean and disperse the silt first. The rotating hollow shaft 801 and the first driving motor 15 can adjust the orientation of the nozzle 8, so that the shape of the water curtain changes, and thus it is suitable for different usage requirements. When the high-pressure pipe 6 is immersed in water, the water flow can be sucked through the filter head 7. Thus, the high-pressure pipe 6 can utilize the water source. At the same time, when the turntable 5 rotates at a high speed, some impurities attached to the filter head 7 can be thrown out to avoid hole blockage.
