DETAILED DESCRIPTION

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] like Figure 1As shown, this embodiment discloses a comprehensive management structure for dredging sediment and ecological restoration of small and medium-sized rivers, including two support frames 1, which are symmetrically arranged, and walking wheels are arranged at the bottom of the two support frames 1. A filter tank 2 is fixedly connected between the two support frames 1, and the filter tank 2 is horizontally arranged. A feed port is provided on the top of the filter tank 2, and a feed hopper 4 is fixedly connected to the feed port. The riverbed sludge can enter the filter tank 2 from the feed hopper 4, and a plurality of filter holes are provided on the tank wall of the filter tank 2, and the sludge can be discharged from the filter tank 2 from the filter holes; as shown in FIG. Figure 4 , 5 As shown, a debris discharge port is provided at the bottom of the filter tank 2, a baffle plate 8 is arranged at the debris discharge port, a plurality of filter holes are also arranged on the baffle plate 8, arc-shaped fixing plates 10 are arranged at both ends of the baffle plate 8, both ends of the fixing plates 10 are fixed to the filter tank 2 by screws 11 and nuts 12, two fixing plates 10 are against both ends of the baffle plate 8, sliding holes are provided on the fixing plates 10, fixing holes corresponding to the sliding holes are provided in the baffle plate 8, an insert plate 9 is slidably arranged in the fixing hole, and both ends of the insert plate 9 pass through the two sliding holes respectively, so as to fix the baffle plate 8 at the debris discharge port.

[0029] like Figure 1 , 2 As shown in Figures 3 and 4, the two support frames 1 are symmetrically provided with an oscillation mechanism 3, which includes a motor 38, a first rotating rod 31, a transmission member 39, a cam 32, a mounting frame 33, and an oscillation plate 311. The motor 38 is fixedly installed on the support frame 1, one end of the first rotating rod 31 is connected to the output shaft of the motor 38 through the transmission member 39, the cam 32 is fixedly arranged at the other end of the first rotating rod 31, the mounting frame 33 is fixedly arranged on the support frame 1, a vertical rod 35 is vertically fixedly arranged inside the mounting frame 33, and an L-shaped vertical rod 35 is arranged on the vertical rod 35. The connecting rod 36 is slidably connected with the vertical rod 35 through the slider 34, and the connecting rod 36 can slide along the vertical rod 35. The vertical rod 35 is sleeved with a spring 310, and the upper end of the spring 310 is fixedly connected with the connecting rod 36, and the lower end of the spring 310 is fixedly connected with the mounting frame 33. The oscillation plate 311 is detachably connected to one end of the connecting rod 36 through the threaded rod 5, and the oscillation plate 311 is arranged directly above the filter tank 2. The other end of the connecting rod 36 is rotatably provided with two rollers 37, and the two rollers 37 are both fitted with the cam 32. It can be understood that when the motor 38 drives the first rotating rod 31 to rotate, the cam 32 will rotate, and the cam 32 will cooperate with the two rollers 37 to drive the connecting rod 36 to move upward periodically during the rotation process. Under the action of the spring 310, the connecting rod 36 will periodically drive the oscillation plate 311 to hit the filter tank 2, thereby improving the efficiency of filtering sludge.

[0030] like Figure 3 As shown, the oscillation plate 311 is in an arc shape, the inner diameter of the oscillation plate 311 is equal to the outer diameter of the filter tank 2 , and a pad 312 is provided on one side of the oscillation plate 311 close to the filter tank 2 .

[0031] like Figure 5 As shown, a second rotating rod 6 is axially rotated in the filter tank 2, and a plurality of scrapers 7 are arranged on the second rotating rod 6. The scrapers 7 are arranged along the radial direction of the filter tank 2, and the scrapers 7 are used to stir the sludge in the filter tank 2, as shown in FIG. Figure 4 As shown, one end of the second rotating rod 6 extends out of the filter tank 2 and is connected to the first rotating rod 31 as a whole, so that when the motor 38 drives the first rotating rod 31, the second rotating rod 6 also rotates synchronously, saving power resources.

[0032] The implementation principle of the integrated management structure for dredging and ecological restoration of small and medium-sized rivers is as follows: when it is necessary to dredge and repair the riverbed silt, the staff can dig out the riverbed silt through an external excavator, and place the external belt conveyor between the two support frames 1 and above the filter tank 2, and then pour the silt into the filter tank 2 through the feed hopper 4. When the silt enters the filter tank 2, the fluid silt flows down the filter holes of the filter tank 2, while the stones in the silt remain in the filter tank 2. The motor 38 is started by the external controller. The start of the motor 38 can drive the first rotating rod 31 to rotate through the transmission member 39. The rotation of the first rotating rod 31 can drive the cam 32 to rotate. When the cam 32 rotates, the roller 37 and the connecting rod 36 move upward, and the connecting rod 36 rises. The movement can pull the spring 310 and drive the oscillation plate 311 to move upward. When the cam 32 rotates to 180 degrees, the oscillation plate 311 rises to the maximum height. When the cam 32 rotates to 270 degrees, the roller 37 loses its support, and the spring 310 rebounds, driving the connecting rod 36 and the oscillation plate 311 to accelerate the downward movement, thereby oscillating the filter tank 2 and accelerating the falling of the sludge; at the same time, when the first rotating rod 31 rotates, it can drive the second rotating rod 6 to rotate, and the rotation of the second rotating rod 6 can drive the scraper 7 to rotate, thereby stirring the sludge entering the filter tank 2, further accelerating the falling of the sludge. After the sludge screening is completed, the staff can pull out the plug plate 9 and unscrew the nut 12, and remove the baffle 8 to discharge the stones in the filter tank 2.

[0033] The present embodiment provides a comprehensive management structure for dredging the bottom mud and ecological restoration of small and medium-sized rivers. By setting up an oscillation mechanism 3, the filter tank 2 can be repeatedly oscillated when dredging the river mud, thereby accelerating the falling of the mud, quickly screening the mud and the stones and garbage in the mud, and improving the management efficiency of the mud.

[0034] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
