Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dredging devices, in particular to a dredging device. Background Art
[0002] River regulation refers to engineering measures for controlling and transforming rivers, which belongs to the category of water conservancy projects. River regulation generally includes projects such as river training, dredging, and bank protection. In natural rivers, erosion and sedimentation often occur, which are likely to cause water disasters and hinder the development of water conservancy. To meet the requirements of eliminating disasters and promoting benefits, appropriate measures must be taken to rectify the river. The specific measures for river regulation include river training, dredging, and bank protection. During the dredging process, dredging devices are usually used to stir the silt deposited at the bottom of the river into a turbid water state and let it flow away with the river water, or to fish out the silt in the river from the riverbed, thus playing a role in dredging.
[0003] When the dredging device pumps out silt, it often pumps out silt blocks and waterweeds together. At this time, it is necessary to break up the silt blocks and cut off the waterweeds to prevent blocking the filter screen and the pump, thus affecting the pumping efficiency.
[0004] In the prior art, several stirring rods are usually used to break up the silt blocks by high-speed stirring, and a spiral cutting blade is used to cut off the part of the waterweed root that is not sucked in. However, when the stirring rod encounters waterweeds, the waterweeds are easily wound around it, and the strong pulling force of its root is likely to damage the rotating stirring rod. When the spiral cutting blade encounters silt blocks, it is easily damaged by collision. Therefore, it is difficult to handle the mixed silt with both waterweeds and silt blocks. Summary of the Utility Model
[0005] Based on this, in view of the above technical problems, it is necessary to provide a dredging device.
[0006] To achieve the above object, the utility model provides a dredging device, which includes a box body and an input pipe. A vacuum generating device is installed on the box body, and the output end of the box body is communicated with the input pipe. A rotating shaft is rotatably connected to the input pipe, and a rotary driving device is installed on the input pipe. The output end of the rotary driving device is in transmission connection with the rotating shaft. An inner ring and an outer ring are installed on the rotating shaft. A number of corresponding sliding grooves are provided on the inner ring and the outer ring. The same stirring plate is slidably clamped in the sliding grooves. Elastic components are installed on both sides in the sliding grooves, and the output ends of the elastic components are connected to the stirring plate. A blade is slidably connected in the stirring plate. An arc-shaped groove is provided on the stirring plate. Fixing bolts are threadedly connected to both the inner ring and the outer ring. The blade is threadedly connected to the fixing bolt, and the fixing bolt is slidably clamped in the arc-shaped groove.
[0007] Preferably, a screen is installed in the box body. The screen is inclined. An output pipe is provided below the screen. A valve is installed on the output pipe, and a storage chamber is provided at the output end of the screen.
[0008] Preferably, U-shaped sliders and sliders are respectively installed on both sides of the stirring plate. Both the U-shaped sliders and the sliders are slidably clamped in the chute, and the U-shaped sliders are located on the side where the blades slide out.
[0009] Preferably, a number of connecting rods are installed on the inner ring and the outer ring, and the connecting rods are connected to the rotating shaft.
[0010] Preferably, multiple groups of the inner ring and the outer ring are provided in the axial direction of the rotating shaft.
[0011] Preferably, a box door is slidably clamped on one side of the storage chamber.
[0012] Compared with the prior art, the technical solution has at least one of the following beneficial effects:
[0013] Through the cooperative setting of the stirring plate and the blades, under normal circumstances, the stirring plate is used to stir and break the sludge blocks. When the waterweeds are entangled, the stirring plate can be driven to slide in the chute, so that the blades can be exposed to cut the waterweeds, thus realizing the synchronous treatment of the sludge blocks and the waterweeds, and improving the practicability;
[0014] The sludge is output through the output pipe at the bottom of the sieve, and the stones fall into the storage chamber through the guidance and absorption of the sieve and the vacuum generating device, thus realizing the separate treatment of the stones and the sludge.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0021] Please refer to Figures 1 to 4 , an embodiment of the present application provides a dredging device, including a box body 1 and an input pipe 2. A vacuum generating device 3 is installed on the box body 1, and the vacuum generating device 3 can be a vacuum pump. The output end of the box body 1 is communicated with the input pipe 2. A rotating shaft 4 is rotatably connected to the input pipe 2. A rotation driving device 5 is installed on the input pipe 2, and the rotation driving device 5 can be a motor. The output end of the rotation driving device 5 is drivingly connected to the rotating shaft 4. An inner ring 6 and an outer ring 7 are installed on the rotating shaft 4. A number of corresponding sliding grooves 8 are provided on the inner ring 6 and the outer ring 7. The same stirring plate 9 is slidably clamped in the sliding grooves 8. Elastic components 10 are installed on both sides in the sliding grooves 8, and the elastic components 10 can be strong springs. The output end of the elastic component 10 is connected to the stirring plate 9. A blade 11 is slidably connected in the stirring plate 9. An arc-shaped groove 12 is provided on the stirring plate 9. Fixing bolts 13 are threadedly connected to both the inner ring 6 and the outer ring 7. The blade 11 is threadedly connected to the fixing bolt 13, and the fixing bolt 13 is slidably clamped in the arc-shaped groove 12. The stirring plate 9 abuts against the rotating shaft 4 and can slide along its surface.
[0022] In this embodiment, the box body 1 and the input pipe 2 can be connected by a relatively long hose, so that the bottom of the input pipe 2 can be placed underwater for sludge extraction. The vacuum generating device 3 sucks the sludge mixture from the bottom of the input pipe 2 through the box body 1. When sucking, the rotation driving device 5 drives the rotating shaft 4 to rotate, and the inner ring 6 and the outer ring 7 installed thereon rotate synchronously with the rotating shaft 4. When encountering sludge blocks, the elastic components 10 in the sliding grooves 8 support the stirring plate 9, so that when the stirring plate 9 collides with the sludge blocks or stones, it is not easy to slide in the sliding grooves 8. When waterweeds are sucked in and wound around the stirring plate 9 and the stirring shaft 4, the relatively large pulling force of the roots of the waterweeds and the force of the stirring shaft 4 driving the rotation enable the stirring plate 9 to slide in the sliding grooves 8, so that the blade 11 installed therein through the fixing bolt 13 slides out relative to the stirring plate 9, thereby cutting the waterweeds from their roots, making the waterweeds shorter and able to be sucked away, thus reducing damage to the device. When the stirring plate 9 moves, the fixing bolt 13 slides in the arc-shaped groove 12, so that the blade 11 still remains fixed relative to the inner ring 6 and the outer ring 7; both the inner ring 6 and the outer ring 7 are annular, so when the waterweeds pass by, they will slide along their surfaces to the stirring plate 9.
[0023] In some embodiments, to facilitate the separate collection of the undispersed sludge blocks and stones in the sludge mixture, a screen 14 is installed inside the box body 1. The screen 14 is inclined. An output pipe 15 is provided below the screen 14, and a valve is installed on the output pipe 15. The valve can be an electromagnetic valve. A storage chamber 16 is provided at the output end of the screen 14. Due to the suction of the vacuum generating device 3 and the action of its own gravity, the sludge can pass through the screen 14 and be output from the output pipe 15, while the sludge blocks and stones can roll into the storage chamber 16 for collection. When starting the dredging, the valve on the output pipe 15 is closed, and when a certain amount of sludge is stored in the box body 1, the valve can be opened so that the sludge can be discharged; when discharging, the sludge should be kept at a certain height to prevent air leakage from the output pipe 15 and affect the suction of the input pipe 2.
[0024] In some embodiments, to facilitate the blade 11 to slide out relative to the stirring plate 9 from one side of the stirring plate 9, U-shaped sliders 17 and sliders 18 are respectively installed on both sides of the stirring plate 9. The U-shaped sliders 17 and the sliders 18 are both slidably clamped in the chute 8, and the U-shaped slider 17 is located on the side where the blade 11 slides out. The U-shaped slider 17 prevents collision with the blade 11.
[0025] In some embodiments, to facilitate the installation of the inner ring 6 and the outer ring 7 on the rotating shaft 4, a number of connecting rods 19 are installed on the inner ring 6 and the outer ring 7, and the connecting rods 19 are connected to the rotating shaft 4.
[0026] In some embodiments, to improve the efficiency of crushing sludge blocks and dividing waterweeds, multiple groups of the inner ring 6 and the outer ring 7 are provided in the axial direction of the rotating shaft 4.
[0027] In some embodiments, to facilitate the collection of the sludge blocks and stones collected in the storage chamber 16, a box door 20 is slidably and sealingly clamped on one side of the storage chamber 16.
[0028] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
