Description

Technical Field

[0001] The invention belongs to the technical field of riverbed mud excavation, and in particular relates to a riverbed mud excavation device. Background Art

[0002] River dredging generally refers to the management of river channels, which is a water conservancy project. The silt deposited on the riverbed is blown and stirred into turbid water through mechanical equipment, which flows away with the river water, thereby playing a role in dredging. Or the silt is transported to the river bank with a bucket. River silt has increasingly affected the normal performance of various functions such as flood control, drainage, irrigation, water supply, and navigation. Excavation of riverbed mud is very necessary.

[0003] Existing riverbed mud excavation devices usually use a bucket to turn over and excavate the silt, and then transport it to the shore. However, the silt remaining inside the equipment is difficult to handle. The silt is corrosive and can easily cause the thickness of the inner wall of the equipment to change. Therefore, the silt remaining on the side wall of the device is more difficult to clean. In addition, the existing bucket excavation method is difficult to completely remove the silt.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: This solution provides a riverbed mud excavation device, which effectively solves the problem that existing riverbed mud excavation solutions are difficult to handle the residual silt inside the equipment and difficult to provide a good excavation effect. This method brings the following advantages:

[0018] (1) In order to solve the problem that the existing riverbed sediment excavation scheme is difficult to deal with the silt remaining inside the equipment, the present invention proposes a propulsion scraping component and a vibration excavation component. The movement of the excavator can drive the equipment to move through the moving wheels. In the process of the equipment moving with the excavator, the riverbed sediment can be better excavated and removed through the autonomous vibration of the vibration excavation bucket. The vibration excavation bucket moving with the excavator can send the silt along the middle transition frame into the silt container, thereby storing the silt, completing the automated silt excavation and providing a more thorough silt removal effect.

[0019] (2) The propulsion scraping assembly can be adaptively processed according to the side wall of the sludge container after being corroded by silt. Before the sludge is excavated, the electrorheological fluid in the deformation accommodating membrane is fluid. The deformation accommodating membrane is soft at this time and can produce free deformation. When processing is required, the two sets of vertical parts can be adjusted to restore them to fit on the inner and outer sides of the sludge container side wall. At this time, the adsorption magnets in the two sets of vertical parts can be adsorbed on the side wall of the sludge container. For sludge containers of different thicknesses, the two sets of scrapers can be adaptively fitted on their side walls. The hard deformation accommodating membrane is moved on the side wall of the sludge container by rolling small balls along the inner and outer walls of the sludge container. The scrapers can thoroughly and efficiently scrape off the sludge remaining on the side wall of the sludge container. This solution can cope with sludge containers of different thicknesses with changed inner walls, effectively preventing sludge from accumulating on the side wall of the sludge container.

[0020] (3) The magnetic shielding plates between adjacent magnet housings can prevent magnetic adsorption between adjacent upper and lower adsorption magnets in the same vertical section, thereby preventing the treatment of sludge on the inner wall of the sludge container from being affected.

[0043] When in use, the device is first installed on the excavator through the mounting bracket 32, so that the device enters the river channel, and the moving wheel 18 rolls forward in the river channel, so that the movement of the excavator can drive the device to move through the moving wheel 18, so that the moving wheel 18 drives the auxiliary turntable 19 to rotate through the wheel body connecting shaft 29, and then drives the transmission wheel 21 to rotate through the transmission belt 20, so that the centrifugal turntable 23 rotates synchronously, and the central driving connecting rod 24 is driven to swing by the centrifugal rotating transmission column 30, so that the side crank swing rods 26 on both sides are driven to reciprocate around the hinge between them and the main fixed bracket 31 through the swing connecting plate 25, so that the bottom of the side crank swing rod 26 swings back and forth, and the centrifugal rotating transmission column 30 drives the central driving connecting rod 24 to swing, and the side crank swing rods 26 on both sides are driven to reciprocate around the hinge between them and the main fixed bracket 31 through the swing connecting plate 25.

After the sludge excavation is completed, the excavated sludge is moved elsewhere, and a portion of sludge remains in the sludge container 5. After long-term operation, the thickness of the inner wall of the sludge container 5 changes due to the corrosiveness of the sludge. When treatment is required, the vertical portion 14 previously located outside the sludge container 5 is flipped into the sludge container 5, so that the two groups of vertical portions 14 are restored to fit the inner and outer sides of the side wall of the sludge container 5. At this time, the adsorption magnets 8 in the two groups of vertical portions 14 can be adsorbed on the side wall of the sludge container 5. For sludge containers 5 of different thicknesses, the two groups of scrapers The plates 7 can be adaptively fitted on their side walls. At this time, the control button 17 is pressed, and an electric field is generated between the parallel plate capacitors 15. Several groups of parallel plate capacitors 15 make the electrorheological fluid 16 in the deformation accommodating membrane 10 solid, so the deformation accommodating membrane 10 is fixed in shape at this time. The output end of the electric push rod 6 is controlled to extend, and the small ball 12 rolling along the inner and outer walls of the sludge container 5 makes the hard deformation accommodating membrane 10 fit and move on the side wall of the sludge container 5.
