Description

Technical Field

[0001] The invention belongs to the technical field of dredging machinery, and in particular relates to dredging equipment for improving pond environment. Background Art

[0002] One of the main functions of a pond is to store water. In rural areas, ponds can collect rainwater to provide irrigation water for fields and ensure crop yields. In cities, ponds can retain rainwater, replenish groundwater, and enrich the capillaries of sponge cities. When used for a long time, a large amount of silt will accumulate at the bottom of the pond, which will affect the water storage capacity of the pond. Therefore, the silt at the bottom of the pond must be desilted in time.

[0025] The center of gravity adjustment device 5 is installed in the buoy 1. The center of gravity adjustment device 5 includes a second motor 505 and a counterweight plate 502. One side of the second motor 505 is fixedly installed on one side of the inner wall of the buoy 1. The output shaft of the second motor 505 is connected to the second threaded rod 504. A nut is embedded in the counterweight plate 502, and the inner wall of the nut is threadedly connected to the outer wall of the second threaded rod 504. Two sliding sleeves are embedded in the counterweight plate 502, and the nut is located in the middle of the two sliding sleeves. A long sliding rod 50 is slidably connected in the sliding sleeve. 1. One end of the long sliding rod 501 is connected to one side of the inner wall of the buoy 1, and the other ends of the two long sliding rods 501 are connected to the same support plate 503. The bottom of the support plate 503 is connected to the bottom of the inner wall of the buoy 1, and the end of the second threaded rod 504 away from the second motor 505 is rotatably connected to one side of the support plate 503.

[0026] The specific implementation method is as follows: by setting a center of gravity adjustment device 5, the second threaded rod 504 is driven to rotate by the output shaft of the second motor 505, so that the second threaded rod 504 drives the counterweight plate 502 embedded with a nut to move, and by setting a moving wheel 507 to move on the inner wall of the pontoon 1, the counterweight plate 502 is converted from sliding friction to rolling friction, thereby making the counterweight plate 502 move more smoothly, and the center of gravity of the pontoon 1 is changed when the counterweight plate 502 moves in the pontoon 1, thereby avoiding the pontoon 1 from tilting forward or backward due to the change in the center of gravity position when adjusting the angle, thereby ensuring the stability of the device during operation, and supporting the counterweight plate 502 by setting a long slide rod 501 to avoid the counterweight plate 502 from offsetting during movement, causing jamming and affecting operation, thereby ensuring the normal operation of the device.

[0027] Working principle: When in use, after placing the device to the desired position, the first motor 401 drives the first threaded rod 403 to rotate, thereby causing the first threaded rod 403 to drive the threaded seat 404 to move, thereby causing the threaded seat 404 to drive the hinge block 414 to move upward through the second hinge seat 410, thereby causing the hinge block 414 to drive the plug-in block 415 to move, thereby causing the plug-in block 415 to slide in the slide groove through the slider 416, thereby causing the slider 416 to drive the connecting plate 409 to move upward, thereby causing the connecting plate 409 to drive the first hinge seat 408 to move, and the first hinge seat 408 drives the rotating plate 405 to rotate, and then the rotating plate 405 drives the suction module 2 to adjust the angle, so that the device can adjust the suction angle as needed, so that the suction box 3 is always in contact with the bottom of the pond, ensuring the suction efficiency. When the device adjusts the angle, the second motor 505 output shaft drives the second threaded rod 504 to rotate, so that the second threaded rod 504 drives the counterweight plate 502 embedded with a nut to move, and the center of gravity of the buoy 1 is changed when the counterweight plate 502 moves in the buoy 1, avoiding the change of the center of gravity position when the angle is adjusted. The change causes the float 1 to tilt forward or backward, thereby ensuring the stability of the device during operation. When the device is sucking, the filter plate 11 is used to filter stones and branches to prevent stones and branches from entering and damaging the suction module 2. At the same time, the output shaft of the third motor 607 drives the rotating disk 605 to rotate, and then the rotating disk 605 drives the sliding rod 608 to rotate, so that the sliding rod 608 drives the rotating ring 609 to rotate, and the rotating ring 609 drives the rotating rod 610 to rotate, and the rotating rod 610 drives the stirring rod 604 on the outer wall to rotate, so that the stirring rod 604 can rotate the sucked mud. The slurry blocks are stirred and broken up to prevent larger and stickier mud blocks from clogging the suction module 2 and reducing the suction efficiency. Then, the rotating rod 610 drives the screw sleeve 603 embedded in the built-in groove 602 to rotate, and the screw sleeve 603 rotates on the outer wall of the reciprocating screw rod 611. The reciprocating screw rod 611 drives the screw sleeve 603 to move back and forth, and then the screw sleeve 603 drives the rotating rod 610 to move back and forth, so that the rotating rod 610 drives the stirring rod 604 to rotate and move horizontally at the same time, thereby improving the efficiency of the stirring rod 604 in breaking up the mud blocks.
