Description

Technical Field

[0001] The invention relates to the technical field of wetland environmental protection, in particular to a silt removal device with a double anti-clogging structure. Background Art

[0002] Wetland environmental protection refers to the protection and restoration of wetland ecosystems through a series of measures and strategies to maintain their ecological functions and biodiversity. Wetlands refer to areas that are covered or saturated with water for a long time or periodically, including swamps, mires, wet grasslands, mangroves and saline-alkali land.

[0003] When protecting the wetland environment, dredging equipment is needed to remove silt from the wetland to maintain its ecological balance and water quality.

When the existing common silt removal device is sucking sludge, in order to prevent larger impurities from entering the pipe of the silt removal device, a filter is generally installed at the pipe opening.

[0020] The present invention provides a dredging device with a double anti-clogging structure, which has the following beneficial effects:

[0021] The dredging device with a double anti-clogging structure uses an anti-clogging component. When the reduction motor is started, the rotating gear ring and the incomplete gear ring are driven to rotate through the fourth pinion. When the incomplete gear ring is meshed with the first middle gear, the second rotating tube is driven to rotate through the first middle gear and the second large gear. When the teeth on the incomplete gear ring are separated from the first middle gear, they are immediately meshed with the second pinion. When the second pinion rotates, the second rotating tube is driven to rotate in the opposite direction through the third pinion and the second large gear. When the second rotating tube rotates, it drives the rotating plate and the first large gear to rotate. The rotation of the rotating plate drives several groups of scrapers and the first cutting knife to rotate. The several groups of scrapers and the first cutting knife perform intermittent forward and reverse rotations. The first cutting knife cuts the silt and impurities around the filter screen, and the scraper scrapes the impurities attached to the outer wall of the filter screen to prevent larger impurities from clogging the filter screen, which causes the dredging device to be unable to perform dredging work normally.

[0022] The dredging device with a double anti-clogging structure has an anti-clogging component. When the dredging device is used to absorb sludge, the reduction motor starts to drive the rotating gear ring and the incomplete gear ring to rotate through the fourth small gear. When the incomplete gear ring is engaged with the first middle gear, the second rotating tube is driven to rotate through the first middle gear and the second large gear. The second rotating tube rotates through the first large gear and the four first small gears to drive the four groups of rotating rods and the second cutting knife to rotate, so as to cut the sludge entering the cavity composed of the outer shell, the connecting plate, the filter screen and the mounting shell, so that the sewage suction pump body can absorb the sludge more smoothly.

[0023] The dredging device with a double anti-clogging structure uses an anti-clogging component. When the dredging device is used to absorb silt, the reduction motor starts to drive the rotating gear ring to rotate through the fourth small gear. The rotating gear ring drives the eccentric wheel to rotate and vibrate through the second middle gear, the third large gear and the first rotating tube, and at the same time drives the shell component and the anti-clogging component to vibrate, thereby preventing large impurities from adhering to the shell component and the anti-clogging component, avoiding impurities from clogging the dredging device, and cooperates with several groups of scrapers and the first cutting knife to form a double anti-clogging structure, so that the dredging device can dredge smoothly.

[0024] The dredging device with a double anti-clogging structure can be quickly disassembled through a connecting pipe assembly when the dredging device needs to be maintained by rotating the first internally threaded pipe and the first externally threaded pipe, and by rotating the second internally threaded pipe and the second externally threaded pipe, thereby improving the convenience of maintaining the dredging device.

[0025] The dredging device with a double anti-clogging structure uses a cleaning component. When the dredging device needs to be cleaned, a water pipe is installed with an externally threaded water inlet pipe, and then a water pump is used to draw water into the annular pipe. The water is sprayed out through a plurality of nozzles at the bottom of the annular pipe to rinse the internal parts of the outer shell. When the dredging device is cleaned, the internal parts of the outer shell can be automatically rinsed, thereby improving the convenience of cleaning the dredging device and improving the cleaning work efficiency.
