[0021] See also Figure 1-4 The present invention provides an embodiment of a highly efficient riverbed sediment cleaning device, comprising a fixing base 1, a crushing motor 2 being fixedly mounted at the center of the upper surface of the fixing base 1 by a fixing bolt, the output shaft of the crushing motor 2 passing through the fixing base 1 and being fixedly connected to a transmission shaft 3, a dredging disc 4 being fixedly mounted at the bottom end of the transmission shaft 3, and a plurality of circumferentially distributed crushing cutters 5 being fixedly mounted on the outer surface of the dredging disc 4 by welding;

[0022] This structural design can work through the provided crushing motor 2. When the crushing motor 2 is working, it drives the dredging disc 4 at the tail end to rotate at high speed through the transmission shaft 3. Since a number of circumferentially distributed crushing cutters 5 are provided on the outside of the dredging disc 4, when the dredging disc 4 rotates, it will synchronously drive the crushing cutters 5 to rotate at high speed. In this way, the bottom mud of the river water body can be cut and crushed by the high-speed rotating crushing cutters 5, which is convenient for subsequent mud suction and cleaning.

[0023] A number of evenly distributed sludge suction pumps 6 are fixedly installed on the outer side of the crushing motor 2 and on the upper surface of the fixed base 1. A sludge suction pipe 7 is fixedly installed at the sludge suction port of the sludge suction pump 6. In order to improve the sludge suction protection effect of the sludge suction pipe 7, a sludge suction cover 8 is fixedly installed at the tail end of each sludge suction pipe 7. The sludge suction cover 8 can protect the bottom cover to avoid damage to the pipe. The output port of the sludge suction pump 6 is fixedly connected to a sludge discharge pipe 9. When in actual use, the tail end of the sludge discharge pipe 9 can be placed on the river bank to transport and remove the bottom mud.

[0024] According to the above structural description, after the crushing cutter 5 is crushed, the sludge suction pump 6 can be started. The sludge suction pump 6 can be used to suck the sludge through the sludge suction pipe 7 and the sludge suction cover 8. The bottom sludge sucked out by the sludge suction pump 6 can be discharged through the sludge discharge pipe 9, thereby completing the cleaning work of the riverbed sludge.

[0025] Furthermore, in order to prevent the mud suction pipe 7 from blocking the crushing cutter 5 , the length of the mud suction pipe 7 is shorter than the length of the transmission shaft 3 .

[0026] In this embodiment, in order to facilitate the installation of the cleaning device of the present invention at the tail end of the river management vessel, two sets of symmetrically distributed front fork rods 10 are fixedly installed on the outer wall directly in front of the fixing seat 1, and a mounting plate 11 is fixedly installed between the top ends of the two sets of front fork rods 10;

[0027] Furthermore, fixing holes 12 are provided at the four corners of the outer surface of the mounting plate 11, and the fixing holes 12 are threaded through holes;

[0028] The front fork rod 10 can be used as an outward extension structure to provide a certain spacing space for installation on the hull, and the mounting plate 11 and the fixing hole 12 can be used to install the utility model as a whole at the tail end of the hull, so that it can be driven by the river management ship to dredge the bottom mud in the river, achieving a targeted mobile dredging effect.

[0029] Furthermore, in order to improve the integrity and structural strength of the front fork rod 10, a plurality of groups of transverse connecting rods 15 are fixedly installed between the two opposite front fork rods 10 by welding, and the two groups of front fork rods 10 can be reinforced by the provided transverse connecting rods 15.

[0030] In this embodiment, in order to reduce the gravity effect of the hull in the river channel, the outer surface of the fixed seat 1 is fixedly installed with equally spaced support arm rods 13, and an air float 14 is fixedly installed below the top of each support arm rod 13. The air float 14 can be used to float the equipment, reduce the force of the equipment sinking in the water, provide a certain upward buoyancy, and thus reduce the travel burden of the hull.

[0031] Working principle: When the utility model is actually used, it can be installed on the tail end of a river channel regulation vessel through the front fork rod 10 and the mounting plate 11, so that it can be driven by the river channel regulation vessel to dredge the bottom mud in the river channel, achieving a targeted mobile dredging effect;

[0032] When the machine is turned on, the crushing motor 2 can be used to work. When the crushing motor 2 is working, it will drive the dredging disc 4 at the tail end to rotate at high speed through the transmission shaft 3. Since a number of circumferentially distributed crushing cutters 5 are provided on the outside of the dredging disc 4, when the dredging disc 4 rotates, it will synchronously drive the crushing cutters 5 to rotate at high speed. In this way, the bottom mud of the river water body can be cut and crushed by the crushing cutters 5 that rotate at high speed, which is convenient for subsequent mud suction and cleaning.

[0033] The bottom mud after cutting and stirring can float above the silt removal plate 4. At this time, the sludge suction pump 6 can be started. The sludge suction pump 6 can be used to suck the cut and crushed sludge through the sludge suction pipe 7 and the sludge suction cover 8. The bottom mud sucked out by the sludge suction pump 6 can be discharged through the sludge discharge pipe 9, thereby completing the cleaning of the riverbed mud.

[0034] In order to reduce the gravity effect of the hull in the river, the utility model has support arms 13 distributed at equal intervals fixedly installed on the outer surface of the fixed seat 1, and an air float 14 is fixedly installed below the top of each support arm 13. The air float 14 can be used to float the equipment, reduce the force sinking effect of the equipment in the water, provide a certain upward buoyancy, and thus reduce the travel burden of the hull.

[0035] The utility model can complete the automatic crushing and mud suction and discharge of riverbed mud through the coordinated use of the above-mentioned structure, and can be installed on a river channel regulation ship for supporting use. The movement of the river channel regulation ship drives the entire equipment to move as a whole, so that the riverbed mud can be removed in a targeted manner. Compared with the existing manual addition method, the utility model has a more direct crushing and mud suction effect, can directly crush and clean the bottom mud, has high cleaning efficiency, has the technical characteristics of efficient bottom mud cleaning, and has a simple overall structure. The power equipment is all placed on the surface of the river water body, is easy to maintain, and is suitable for popularization and use.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
