Underwater garbage dredger with anti-wrap scraper

Abstract

The invention provides an underwater garbage dredger with an anti-wrap scraper. The dredger comprises an operating room, a power device, a hull, a mud storage tank, a front cleaning device with a cutter tooth conveyor belt, a bracket and the anti-wrap scraper. The dredger is characterized in that the operating room and the power device are arranged at the rear part of the hull; the mud storage tank is arranged at the middle part of the hull; the front cleaning device with the cutter tooth conveyor belt and the bracket are arranged in the front of the hull; the lower end of the bracket is fixedly connected with the hull; the upper end of the bracket is connected with the front cleaning device with the cutter tooth conveyor belt through a bracket shaft; the front cleaning device with the cutter tooth conveyor belt comprises cutter teeth and the conveyor belt; the cutter teeth are fixed on the surface of the conveyor belt; the anti-wrap scraper is fixedly connected with the hull through a support rod; a digging tooth in and out groove is arranged in the surface of the anti-wrap scraper; and an anti-wrap scraper shaft is arranged at the center of the anti-wrap scraper. According to the invention, the underwater garbage dredger can clean up soft and hard garbage, and realizes continuous operation; the dredging efficiency is improved; the dredging cost is reduced; and the dredging quality is high.

Description

technical field [0001] The invention relates to environmental protection dredging engineering equipment, in particular to an underwater garbage dredging ship with an anti-winding scraper. Background technique [0002] Due to natural or man-made reasons, a lot of silt is deposited at the bottom of rivers, lakes and reservoirs. In order to purify water, improve the environment and dredge waterways, people usually use dredging ships to clean up the silt. At present, there are many types of dredging ships, and cutter suction dredgers composed of cutters and mud pumps have been widely used. The dredger works by relying on the self-rotation and left-right swing of the reamer installed at the front end of the reamer bridge and the suction of the dredger pump, loosening the soil at a specified depth underwater and sucking and discharging it to the designated unloading area. [0003] However, in the process of long-term use of urban inland rivers, due to the lack of awareness of en...

AI Technical Summary

Problems solved by technology

[0005] In view of the above problems, the present invention provides an underwater garbage dredging ship with an anti-winding scraper. On the surface of the anti-winding scraper, there are excavation tooth entry and exit grooves. The flocculent garbage will be continuously scraped off by the excavating teeth in and out of the slot to prevent the scraper from being wound. The garbage dredging ship can dig deep into the mud layer, which solves the problem of soft garbage entanglement, and at the same time solves the problem of garbage with high hardness due to collision. Damage to the reamer head, mud pump impeller, and blockage of the mud pump can clean up soft and hard garbage, realize continuous operation, improve dredging efficiency, reduce dredging costs, and achieve high dredging quality
