Detailed Description of the Invention
[0035] The following further describes the present utility model with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.
[0036] As Figures 1 to 5As shown in the figure, a silt cleaning device for river regulation in municipal engineering includes a mounting base 1. At one end of the mounting base 1, a silt fishing bucket 11 for fishing silt is rotatably installed. The silt fishing bucket 11 is in a "V" shape, which is convenient for collecting silt. On the top of the mounting base 1, a silt treatment component 2 for separating silt and sewage is installed. The silt treatment component 2 includes a material separation sieve cylinder 21. The material separation sieve cylinder 21 is installed on the top of the mounting base 1 in an inclined and rotatable manner.

A driving shaft 24 is coaxially installed on the output shaft of the driving motor 23. A driving friction wheel 25 is coaxially installed on the driving shaft 24. The driving friction wheel 25 is used to drive the driving ring 22 to rotate. A suction pump 26 is installed on the top of the mounting base 1. The feeding end of the suction pump 26 is connected to the silt fishing bucket 11 through a suction pipe 261.

At the other end of the mounting base 1, a silt collection box 12 is installed. A loosening component 3 for loosening silt is installed on the silt fishing bucket 11. An adjusting component 4 for adjusting the angle of the silt fishing bucket 11 is also installed on the mounting base 1; when it is necessary to dredge the river, the mounting base 1 is driven to move along the river. During the movement of the mounting base 1, the silt fishing bucket 11 will be synchronously pushed to move. During the movement of the silt fishing bucket 11, the silt in the river will be shoveled. The loosening component 3 installed on the silt fishing bucket 11 will stir the silt in the river, so as to facilitate the suction pump 26 to suck the silt and discharge it into the material separation sieve cylinder 21. The driving motor 23 drives the driving shaft 24 to rotate. During the rotation of the driving shaft 24, the driving friction wheel 25 will be synchronously driven to rotate. During the rotation of the driving friction wheel 25, the material separation sieve cylinder 21 will be driven to rotate through friction. During the rotation of the material separation sieve cylinder 21, the silt and the sewage mixed in the silt will be separated. The sewage will fall out of the outside of the material separation sieve cylinder 21 through the through holes on the wall of the material separation sieve cylinder 21. The sludge will move along the length direction of the material separation sieve cylinder 21, and then flow out of the material separation sieve cylinder 21 from the other end and fall into the silt collection box 12.
[0037] As Figures 1 to 5As shown, the loosening assembly 3 includes a stirring motor 31 and a driving gear 32. The stirring motor 31 is fixedly installed on the top of the salvage bucket. The driving gear 32 is coaxially installed on the output shaft of the stirring motor 31.

The driven gear 34 meshes with the driving gear 32. A first bevel gear 35 is coaxially installed on the top of the driving stirring rod 33. A transmission shaft 36 is rotatably installed on the top of the sludge salvage bucket 11. One end of the transmission shaft 36 is coaxially installed with a second bevel gear 361. The second bevel gear 361 meshes with the first bevel gear 35. A plurality of third bevel gears 362 are coaxially and evenly arranged on the transmission shaft 36. A plurality of driven stirring rods 37 are evenly installed on the sludge salvage bucket 11. A fourth bevel gear 38 is coaxially installed on the top of the driven stirring rod 37. The plurality of third bevel gears 362 correspond to the plurality of fourth bevel gears 38 one by one. The third bevel gear 362 meshes with the fourth bevel gear 38. During use, start the stirring motor 31. During the rotation of the stirring motor 31, it will drive the driving gear 32 to rotate synchronously. During the rotation of the driving gear 32, it will drive the driven gear 34 to rotate synchronously, thereby driving the driving stirring rod 33 to rotate synchronously. During the rotation of the driving stirring rod 33, it will synchronously drive the first bevel gear 35 to rotate. During the rotation of the first bevel gear 35, it will drive the second bevel gear 361 to rotate. During the rotation of the second bevel gear 361, it will drive the transmission shaft 36 to rotate. During the rotation of the transmission shaft 36, it will drive the plurality of third bevel gears 362 to rotate synchronously. During the rotation of the third bevel gear 362, it will synchronously drive the corresponding fourth bevel gear 38 to rotate synchronously. During the rotation of the fourth bevel gear 38, it will drive the driven stirring rod 37 to rotate. During the rotation of the driving stirring rod 33 and the driven stirring rod 37, the sludge in the sludge salvage bucket 11 and the sludge in front of the sludge salvage bucket 11 will be broken up, so as to facilitate the suction of the sludge and the subsequent separation of the sludge and sewage through the material separation sieve tube 21.
[0038] As Figures 1 to 5 shown, the adjustment assembly 4 includes a worm gear 41, a worm 42 and an adjustment motor 43. The sludge salvage bucket 11 is rotatably installed on the mounting seat 1 through a rotating shaft 44. The worm gear 41 is coaxially installed on the rotating shaft 44. The worm 42 is rotatably installed on the mounting seat 1. The adjustment motor 43 is fixedly installed on the mounting seat 1. The output shaft of the adjustment motor 43 is coaxially connected to the worm 42. During use, start the adjustment motor 43. During the rotation of the adjustment motor 43, it will synchronously drive the worm 42 to rotate. During the rotation of the worm 42, it will drive the worm gear 41 to rotate synchronously. During the rotation of the worm 42, it will drive the rotating shaft 44 to rotate synchronously, thereby driving the sludge salvage bucket 11 to rotate, so as to be able to adjust the inclination angle of the sludge salvage bucket 11 to adapt to the curved river channel.
[0039] As Figures 1 to 5As shown in the figure, a liquid collecting hopper 13 is embedded inside the mounting base 1. A drain pipe 14 is connected and installed at the bottom of the liquid collecting hopper 13. Liquid blocking plates 15 are arranged on both sides of the material distributing sieve cylinder 21 on the mounting base 1. During use, the sludge and water are pumped into the interior of the material distributing sieve cylinder 21. Then, as the material distributing sieve cylinder 21 rotates, the sludge is separated. The water flows out from the sieve holes on the material distributing sieve cylinder 21 and, under the action of gravity, falls into the liquid collecting hopper 13 and then is discharged along the drain pipe 14. The liquid blocking plates 15 will block the splashing sewage during the rotation of the material distributing sieve cylinder 21. The sludge will move along the length direction of the material distributing sieve cylinder 21 and then fall into the sludge collection box 12.
[0040] As Figures 1 to 5 shown, mounting grooves 111 are formed on both sides of the sludge fishing bucket 11. A telescopic plate 112 is slidably installed in the mounting grooves 111. One end of the telescopic plate 112 is installed with a return spring 113, and the other end of the return spring 113 is connected to the groove wall of the mounting groove 111. During use, when the river channel narrows, the telescopic plate 112 will move along the length direction of the mounting groove 111, and the return spring 113 is compressed, so as to adapt to the current narrowing of the river channel. When the river channel widens, the return spring 113 will elongate, thereby pushing out the telescopic plate 112 to facilitate adapting to the current width of the river channel.
[0041] As Figures 1 to 5 shown, spiral blades 211 are installed on the inner wall of the material distributing sieve cylinder 21. During use, by installing the spiral blades 211 on the inner wall of the material distributing sieve cylinder 21, the residence time of the sludge in the material distributing sieve cylinder 21 can be extended, thereby improving the separation effect of the sludge and the sewage.
[0042] As Figures 1 to 5 shown, a connecting seat 5 is installed on the mounting base 1. A connecting groove 51 is formed on the connecting seat 5. A connecting block 52 is installed on the sludge collection box 12. The connecting block 52 is inserted and installed in the connecting groove 51. A fixing pin 53 is inserted through the connecting seat 5, and the bottom of the fixing pin 53 extends to the connecting block 52. During use, the connecting block 52 on the sludge collection box 12 is inserted and installed in the connecting groove 51, and then the fixing pin 53 is inserted through the connecting seat 5 and then inserted into the connecting block 52, so as to facilitate the detachable connection between the sludge collection box 12 and the mounting base 1. When the sludge collection box 12 is full of sludge, the sludge collection box 12 can be replaced, so as to continuously collect the sludge.
[0043] As Figures 1 to 5As shown in the figure, a first isolation box 54 for protecting the agitation motor 31 is installed on the sludge dredging bucket 11, and a second isolation box 55 for protecting the adjustment motor 43 is installed on the mounting seat 1. By installing the first isolation box 54, the agitation motor can be protected to prevent the water or sludge in the river from affecting the normal rotation of the agitation motor 31. By installing the second isolation box 55, the adjustment motor 43 can be protected to prevent the water or sludge in the river from affecting the normal rotation of the adjustment motor 43.
[0044] As Figures 1 to 5 shown in the figure, a plurality of universal wheels 56 are evenly installed at the bottom of the sludge collection box 12, and four moving wheels 57 are evenly installed at the bottom of the mounting seat 1. A moving motor 58 is embedded in the mounting seat 1, and the output shaft of the moving motor 58 is coaxially connected to the moving wheel 57. During use, when the moving motor 58 is started, the moving motor 58 will drive the moving wheel 57 to rotate during the rotation process. During the rotation process of the moving wheel 57, the mounting seat 1 will be driven to move forward or backward. The universal wheels 56 can facilitate the movement of the sludge collection box 12 following the mounting seat 1.
[0045] As Figures 1 to 5 shown in the figure, stirring blades 39 are installed on both the main stirring rod 33 and the driven stirring rod 37. There are multiple stirring blades 39, and the multiple stirring blades 39 are evenly arranged along the length direction of the main stirring rod 33. When the main stirring rod 33 and the driven stirring rod 37 rotate, the multiple stirring blades 39 installed on themselves will be driven to rotate synchronously. During the rotation process of the stirring blades 39, the effect of loosening the sludge will be improved, so as to facilitate the cleaning of the sludge.
[0046] The implementation principle of this embodiment is as follows: When dredging the river is required, the mounting seat 1 is driven to move along the river. During the movement of the mounting seat 1, the sludge dredging bucket 11 will be synchronously pushed to move. During the movement of the sludge dredging bucket 11, the sludge in the river will be shoveled. The loosening assembly 3 installed on the sludge dredging bucket 11 will agitate the sludge in the river, so as to facilitate the suction pump 26 to suck the sludge and discharge it into the material separation sieve tube 21. The drive motor 23 drives the drive shaft 24 to rotate. During the rotation process of the drive shaft 24, the drive friction wheel 25 will be synchronously driven to rotate. During the rotation process of the drive friction wheel 25, the material separation sieve tube 21 will be driven to rotate through friction. During the rotation process of the material separation sieve tube 21, the sludge and the sewage mixed in the sludge will be separated. The sewage will fall out of the outside of the material separation sieve tube 21 through the through holes on the wall of the material separation sieve tube 21. The sludge will move along the length direction of the material separation sieve tube 21, and then flow out of the material separation sieve tube 21 from the other end and fall into the sludge collection box 12.
