[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a water conservancy project salvage device, comprising a left bucket 1 and a right bucket 2. When the left bucket 1 and the right bucket 2 are combined, they form a complete cylinder, which is convenient for excavating and transferring the silt at the bottom of the river. The left bucket 1 and the right bucket 2 are connected by a connecting shaft 3, which is installed on the transmission arm of the excavator through the connecting shaft 3, and the left bucket 1 and the right bucket 2 are driven to rotate around the connecting shaft 3 by the power device of the excavator. It is a prior art. The front of the right bucket 2 is fixedly connected to a stepper motor 4. The stepper motor 4 has good controllability and high control accuracy. A sealing cover 19 is provided on the front of the right bucket 2. The stepper motor 4 is arranged inside the sealing cover 19, so that when excavating silt on the bottom of the water, water will not enter the interior of the sealing cover 19 and affect the stepper motor 4.

[0034] Reference Figure 3 、 Figure 4 The rear side of the output shaft of the stepping motor 4 is fixedly connected to the rotating shaft 5, and the circumferential surface of the rotating shaft 5 is fixedly connected to the crushing teeth 6. The inner wall of the right bucket 2 is fixedly connected to the cutting blade 7. The bottom of the cutting blade 7 is provided with cutting teeth. The cooperation of the cutting teeth and the crushing teeth 6 is beneficial to improve the crushing effect of dead branches and debris, and prevent dead branches, fallen leaves and other debris from clogging the interior. The number of crushing teeth 6 and cutting blades 7 are set to multiple, and the crushing teeth 6 and cutting blades 7 are arranged at intervals to improve the crushing effect. A rebound mechanism is provided inside the right bucket 2.

[0035] Reference Figure 4 - Figure 6 The rebound mechanism includes a semi-cylinder 8 and a slider 10. The number of semi-cylinders 8 is set to two groups. The two groups of semi-cylinders 8 are respectively fixedly mounted on the inner walls of the left bucket 1 and the right bucket 2. The semi-cylinder 8 and the pressure block 9 cooperate with each other. The slider 10 is slidably mounted on the inner wall of the crushing teeth 6. The pressure block 9 is fixedly connected to the right side of the slider 10. The semi-cylinder 8 and the pressure block 9 are in intermittent contact. The surface of the pressure block 9 is provided with an arc surface. Through the arc surface of the pressure block 9, when the pressure block 9 contacts the surface of the semi-cylinder 8, the semi-cylinder 8 can push the pressure block 9 to displace.

[0036] Reference Figure 5 、 Figure 6The left side of the slider 10 is fixedly connected to a slide plate 11, and the piston of the slide plate 11 is installed on the inner wall of the crushing tooth 6. The slide plate 11 is elastically connected to the inner wall of the crushing tooth 6 through a spring 12. By setting the spring 12, an elastic force is applied to the slide plate 11 away from the pressure block 9. One end of the spring 12 is fixedly connected to the surface of the slide plate 11, and the other end of the spring 12 is fixedly connected to the inner wall of the crushing tooth 6. The number of springs 12 is set to multiple.

[0037] Reference Figure 5 、 Figure 6 An elastic rubber plate 14 is fixedly connected to the inner wall of the crushing teeth 6. The elastic rubber plate 14 has good resilience. A hydraulic cabin 13 is provided inside the crushing teeth 6. The hydraulic cabin 13 is provided with oil for transmitting pressure. The elastic rubber plate 14 drives the slide plate 11 to move through the oil transmission. A metal ball 15 is provided inside the crushing teeth 6. The metal ball 15 has a large inertial mass.

[0038] Reference Figure 2 、 Figure 3 The bottom of the left bucket 1 and the right bucket 2 are both provided with water filter holes 16 through which water can pass. The water inside the silt is discharged from the water filter holes 16 to the outside of the left bucket 1 and the right bucket 2, thereby reducing the water content of the silt. The bottom of the right bucket 2 is provided with a bite tooth 17, and the bottom of the left bucket 1 is provided with a bite groove 18 that cooperates with the bite tooth 17 to improve the excavation effect.

[0039] Working principle: When in use, the excavator uses the biting teeth 17 on the right bucket 2 to cooperate with the biting groove 18 to dig out the silt from the bottom of the river, and uses the power device of the excavator to drive the right bucket 2 and the left bucket 1 to merge into a cylinder to facilitate the transfer of the silt. Then turn on the power of the stepper motor 4, and the stepper motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the crushing teeth 6 to rotate. The rotation of the crushing teeth 6 will push the dead branches and leaves and other debris in the silt. The crushing teeth 6 continue to rotate until the debris is pushed to the cutting edge 7. Through the cooperation of the cutting teeth and the crushing teeth 6, the crushing teeth 6 will crush the debris as they continue to rotate, thereby reducing the possibility of debris clogging the left bucket 1 and the right bucket 2. The continuous rotation of the crushing teeth 6 improves the effect of crushing debris.

[0040] As the crushing teeth 6 rotate, the rotation of the crushing teeth 6 will drive the metal ball 15 inside the crushing teeth 6 to make a circular motion around the rotating shaft 5, so that the metal ball 15 moves in the direction close to the inner wall of the right bucket 2 under the action of its own inertia. The movement of the metal ball 15 will squeeze the elastic rubber plate 14 and cause the elastic rubber plate 14 to deform, thereby reducing the volume inside the hydraulic cabin 13, thereby increasing the pressure inside the hydraulic cabin 13. The increased pressure pushes the slide plate 11 to overcome the elastic force of the spring 12 and move in the direction close to the inner wall of the right bucket 2. The movement of the slide plate 11 drives the pressure block 9 to move in the direction away from the rotating shaft 5 through the slider 10 until the pressure block 9 and the inner wall of the right bucket 2 are in contact. When the pressing block 9 moves and passes the position of the semi-cylinder 8, the semi-cylinder 8 will squeeze the pressing block 9, causing the pressing block 9 to move toward the rotating shaft 5. When the pressing block 9 leaves the position of the semi-cylinder 8, the pressing block 9 will contact the inner wall of the right bucket 2 again under the action of the spring 12. As the rotating shaft 5 rotates, the pressing block 9 and the semi-cylinder 8 collide continuously. The vibrations generated by these collisions, combined with the rotation of the crushing teeth 6, will cause the sludge to be continuously mixed and oscillated, thereby preventing the sludge from accumulating at the bottom of the cylinder formed by the left bucket 1 and the right bucket 2, causing water to be discharged unsmoothly, thereby further reducing the water content inside the sludge.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
