Description

Technical Field

[0001] This invention relates to the field of agitation and suction dredging technology, specifically to an agitation and suction device for a multi-functional dredging vehicle. Background Technology

[0002] Municipal dredging is a crucial guarantee for the normal operation of urban drainage systems. It can promptly remove silt and debris from pipe networks and waterways, unclog drainage channels, effectively prevent waterlogging during the flood season, and protect the safety of citizens' travel and property. At the same time, it can reduce water pollution problems caused by silt accumulation, improve the urban ecological environment, reduce the risk of pipe corrosion and blockage, extend the service life of facilities, and lay a solid foundation for normal urban production, life, and ecological livability.

[0003] Existing municipal dredging vehicles with agitation and suction devices mostly adopt a step-by-step operation mode of crushing and suction, which results in low operating efficiency. Moreover, when the crushing components rotate and crush the sludge, they are easily entangled and adhered to by debris and viscous sludge, which not only reduces the crushing effect but also increases the operating load of the equipment. At the same time, there is a lack of supporting cleaning structure, which requires the machine to be stopped for manual cleaning of the crushing components, further interrupting the operation process and increasing operation and maintenance costs. It is difficult to adapt to the high-efficiency dredging needs of municipal pipe networks, rivers and other scenarios. Therefore, we propose an agitation and suction device for a multi-functional dredging vehicle. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please see Figures 1 to 4The present invention provides a stirring and suction device for a multi-functional sludge dredging vehicle, including a connector 1 and a U-shaped plate 2. The U-shaped plate 2 serves as the core mounting carrier of the device. A driving mechanism 3 is stably mounted on the surface of the U-shaped plate 2. A crushing mechanism 4 and a cleaning mechanism 5 are correspondingly mounted below the driving mechanism 3. The three work together to achieve power output, hard block crushing and auxiliary cleaning functions in sludge dredging operations. The drive mechanism 3 includes a first gear 35, a second gear 39, and a third gear 302 that rotate synchronously on the top surface of the bottom plate of the U-shaped plate 2. The gears mesh to ensure the stability of power transmission. A connecting pipe 34 is fixedly sleeved in the middle of the first gear 35. The connecting pipe 34 is rotatably sleeved on the bottom plate of the U-shaped plate 2 through bearing cooperation, so as to achieve rotation while ensuring sealing performance. A pump body 31 is detachably installed on the top surface of the U-shaped plate 2 by bolts. The pump body 31 is a self-priming non-clogging sewage pump of model ZWL80-65-160 with a rated flow of 80m³ / h and a rated head of 16m. It is suitable for the transportation needs of mud and sewage in dredging operations and has good anti-clogging performance. The pump body 31 has a conveying pipe 36 and a discharge pipe 37 detachably connected to its inlet and outlet ends via flanges, respectively. The inlet end of the conveying pipe 36 is rotatably connected to the outlet end of the connecting pipe 34 via a rotary joint, ensuring that the conveying pipe 36 can still stably convey the medium during the rotation of the connecting pipe 34. The outlet end of the discharge pipe 37 away from the pump body 31 is connected to the storage bin of the sludge truck via an external hose, so as to realize the centralized collection of mud and sand. The crushing mechanism 4 includes a connecting pipe 2 42 that is detachably connected to the water inlet end of the connecting pipe 1 34 via a thread. The bottom end of the connecting pipe 2 42 is connected to a conical cylinder 41 by welding. Three crushing blades 44 are uniformly fixedly sleeved on the outside of the conical cylinder 41 along the circumferential direction. The crushing blades 44 are made of high manganese steel and the cutting edge is quenched, with a hardness of HRC55 or higher. They can effectively crush underwater obstacles such as silt, debris, etc. Six crushing nails 43 are uniformly fixedly connected to the conical part at the bottom of the conical cylinder 41 along the circumferential direction. The crushing nails 43 are conical with the tip pointing downwards, which can penetrate deep into the bottom layer of silt for piercing and crushing, further improving the crushing effect. The cylinder wall of the conical cylinder 41 is uniformly opened with multiple water inlet holes 45 with a diameter of 20mm along the axial and circumferential directions. The water inlet holes 45 are distributed in a honeycomb pattern, which can ensure that mud and sewage can smoothly enter the interior of the conical cylinder 41, and prevent large impurities from clogging the pipe. The U-shaped plate 2 has mounting holes 1 and 2 through it, corresponding to the installation positions of connecting pipe 1 34 and connecting rod 301. The wall of mounting hole 1 is fixedly connected to a first bearing 33 by interference fit, which can withstand the radial and axial forces generated when connecting pipe 1 34 rotates. The inner ring of the first bearing 33 is fixedly connected to the outer wall of connecting pipe 1 34. The wall of mounting hole 2 is also fixedly connected to a second bearing by interference fit. The inner ring of the second bearing is fixedly connected to the circumferential surface of connecting rod 301. The bottom end of connecting rod 301 is fixedly sleeved with the middle part of third gear 302 to achieve stable rotation of third gear 302. A reinforcing rod 38 is rotatably connected between the top and bottom plates of the U-shaped plate 2. The reinforcing rod 38 is made of 45 seamless steel pipe, and its two ends are connected to the plate body of the U-shaped plate 2 through bearings to ensure structural strength while reducing rotational resistance. The middle part of the second gear 39 is fixedly sleeved on the circumferential surface of the reinforcing rod 38 through a flat key. The top surface of the U-shaped plate 2 is detachably connected to the drive motor 32 through a motor base. The drive motor 32 is a three-phase asynchronous motor of model Y132M-4 with a rated power of 7.5kW and a rated speed of 1440r / min. The output end of the drive motor 32 is detachably connected to the top of the reinforcing rod 38 through a coupling. The drive motor 32 provides power to drive the reinforcing rod 38 to rotate, and then the second gear 39 meshes with the first gear 35 and the third gear 302 to realize the synchronous operation of the entire drive mechanism. In practice, the entire structure is fixedly installed at the end of the robotic arm of the dredging vehicle via connector 1. The robotic arm is adjusted to allow the crushing mechanism 4 to penetrate underwater into the area to be dredged. The drive motor 32 is then started, which drives the reinforcing rod 38 and the second gear 39 to rotate. The second gear 39 simultaneously engages and drives the first gear 35 and the third gear 302 to rotate synchronously. The first gear 35 drives the connecting pipe 1 34, the connecting pipe 2 42, and the conical cylinder 41 to rotate. The crushing blades 44 on the outside of the conical cylinder 41 and the crushing nails 43 at the bottom follow suit. The high-speed rotation crushes hard lumps and debris in the underwater silt. At the same time, the pump body 31 is activated, generating negative pressure. The crushed mud and sewage are sucked in through the connecting pipe 1 34, connecting pipe 2 42 and the water inlet 45 on the conical cylinder 41. The sewage is then transported to the pump body 31 through the conveying pipe 36 and discharged into the storage bin of the sludge removal vehicle through the discharge pipe 37. The coordinated work of the pump body 31 and the crushing mechanism 4 realizes the integrated operation of "crushing-suction-conveying". Moreover, each component adopts a detachable connection method, which is convenient for later maintenance and replacement.

[0018] Example 2: Please see Figures 2 to 5Based on Embodiment 1, the cleaning mechanism 5 includes a cleaning pipe 55 located on one side of the conical cylinder 41 and arranged at an angle. The cleaning pipe 55 is made of stainless steel. Four cleaning nozzles 56 are detachably installed along the length of the pipe body. The cleaning nozzles 56 are high-pressure fan-shaped nozzles with a nozzle orifice diameter of 2.5 mm, a spray angle of 60°, and a spray pressure of up to 0.8 MPa, which can form a dense high-pressure water curtain. The spray direction of the cleaning nozzles 56 is all towards the crushing blade 44 and the crushing nail 43, which is used to wash the silt and debris attached to the surface of the conical cylinder 41 in all directions when it rotates, so as to avoid the attachments affecting the crushing efficiency and rotation flexibility. The cleaning mechanism 5 also includes a transmission rod 53 detachably connected to the bottom end of the connecting rod 301 via a flat key. The transmission rod 53 is coaxially arranged with the connecting rod 301, and the diameter of the transmission rod 53 is the same as that of the connecting rod 301. A cylinder 52 is rotatably sleeved on the circumferential surface of the transmission rod 53 via a third bearing to ensure that the cylinder 52 remains fixed when the transmission rod 53 rotates. The bottom end of the transmission rod 53 extends into the inside of the cylinder 52, and a spiral conveying blade 57 is fixedly connected to the bottom end of the transmission rod 53 by welding. The spiral conveying blade 57 is made of stainless steel, with a blade pitch of 80mm. Its outer diameter is tightly fitted with the inner wall of the cylinder 52, with a gap of no more than 0.5mm, to ensure that the spiral conveying blade 57 can effectively push the liquid in the cylinder 52 to form a negative pressure when it rotates. The water inlet of the cleaning pipe 55 is fixedly connected to the upper part of the cylinder wall of the cylinder 52 by welding. A sealing gasket is provided at the connection to prevent water leakage. Two arc-shaped connecting plates 51 are symmetrically fixedly connected to the outer wall of the cylinder 52. The curvature of the arc-shaped connecting plates 51 is adapted to the outer wall of the cylinder 52. The top surface of the arc-shaped connecting plates 51 is detachably connected to the bottom surface of the U-shaped plate 2 by bolts, thereby firmly fixing the cylinder 52 under the U-shaped plate 2 and ensuring the stability of the overall structure of the cleaning mechanism 5. The bottom end of the cylinder 52 is detachably connected to a filter cover 54 by threads. The filter cover 54 is cylindrical. A stainless steel filter screen with a pore size of 1mm is fixedly connected inside the filter cover 54 by a buckle. The filter screen is used to filter impurities in the water entering the cylinder 52 to prevent impurities from clogging the cleaning nozzle 56 or wearing the spiral conveyor blades 57. In practice, when the drive motor 32 starts, the connecting rod 301 drives the transmission rod 53 to rotate synchronously. The spiral conveying blade 57 at the bottom of the transmission rod 53 rotates at high speed. Because the spiral conveying blade 57 is tightly attached to the inner wall of the cylinder 52, a negative pressure is formed inside the cylinder 52 when it rotates. The sewage in the working area is drawn into the cylinder 52 through the filter cover 54. The sewage is first filtered through the filter screen to remove impurities and then enters the upper part of the cylinder 52. Under the thrust of the spiral conveying blade 57, the filtered water is pressed into the cleaning pipe 5. Inside the 5, a high-pressure water flow is formed. The high-pressure water flow is sprayed out at high speed through the four cleaning nozzles 56 on the cleaning pipe 55, forming a fan-shaped water curtain. At this time, the cone cylinder 41 rotates continuously under the drive mechanism 3. The crushing blade 44 and the crushing nail 43 pass through the spray area of ​​the cleaning nozzle 56 in sequence. The high-pressure water flow continuously washes the surface of the crushing blade 44 and the crushing nail 43, washing off the attached silt, small stones and other debris. The washed-off debris is sucked into the water inlet 45 of the cone cylinder 41 along with the water flow and enters the subsequent conveying channel. If the filter becomes clogged during operation, it can be quickly replaced or cleaned by removing the filter cover 54. The operation is convenient. If the cleaning nozzle 56 becomes clogged, it can be directly removed from the cleaning pipe 55 for unblocking. Through the coordinated work of the cleaning mechanism 5, the crushing mechanism 4, and the driving mechanism 3, the "crushing-cleaning-suctioning-conveying" integration of dredging operation is realized, which effectively reduces equipment failures and improves operation efficiency and continuity. It is especially suitable for complex dredging scenarios with thick sludge and a lot of debris.

[0019] Example 3: Please see Figures 3 to 5 Based on the above embodiments, the structure of the crushing blade 44 of the crushing mechanism 4 is optimized to improve the crushing efficiency. Each crushing blade 44 is ring-shaped and each crushing blade 44 is composed of three arc-shaped cutting blades spliced ​​together. The arc-shaped cutting blades are integrally formed of high manganese steel, and the curvature is adapted to the outer wall of the conical cylinder 41. In each crushing blade 44, the cutting surfaces of the arc-shaped cutting blades on the three crushing blades 44 are arranged alternately up and down to form an interlaced cutting structure with a cutting gap of 5mm, which can effectively avoid the sludge and hard blocks from getting stuck and improve the uniformity of crushing. Four cleaning nozzles 56 are precisely aligned with three crushing blades 44 and a set of crushing nails 43. Three of the cleaning nozzles 56 are aligned with the cutting surfaces of the three annular crushing blades 44, while the remaining cleaning nozzle 56 is directed toward the area where the crushing nails 43 are located, ensuring that the high-pressure water curtain can fully cover the crushed components. In practice, after the drive motor 32 starts, the conical cylinder 41 drives the annular crushing blades 44 to rotate. The staggered arc-shaped cutting blades shear and crush the silt blocks from multiple directions. Combined with the piercing effect of the crushing nails 43, the crushing effect is better. In the synchronously operating cleaning mechanism 5, the corresponding cleaning nozzles 56 spray high-pressure water curtains to specifically wash the staggered cutting surfaces of each crushing blade 44 and the crushing nails 43, thoroughly removing attached debris and ensuring the continuous and stable crushing and suction operations.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
