Integrated high-pressure anti-blocking sucking, flushing and digging dredging equipment

Abstract

The invention relates to integrated high-pressure anti-blocking sucking, flushing and digging dredging equipment. The top of a mechanical arm (1) and a cutting pump (3) are fixedly connected through aflange (14). The interiors of the bottom and the rear wall of the mechanical arm (1) are arranged to be flow channels of a cavity streamline structure and communicate with the cutting pump (3) on theupper portion. A anti-silting jetting device (2) is welded to the back of the mechanical arm (1), and the bottom of the anti-silting jetting device (2) communicates with the interior of the mechanical arm (1). The upper end of the cutting pump (3) is connected with a hydraulic motor (5) through a coupling (4), and body equipment of the cutting pump (3), the coupling (4) and the hydraulic motor (5) is in fixed bolt connection with a mechanical connecting frame (6) through a hoop (7). The integrated high-pressure anti-blocking sucking, flushing and digging dredging equipment integrates the functions of flushing, digging and sucking; and the problem of blocking of a silt suction port can be effectively solved through cooperative carrying work with a digging machine in combination with the spiral structure and the sharp knife edge structure of the cutting pump. The dredging function is remarkably enhanced, the internal silt conveying cavity streamline structure is adopted, hard waste is isolated based on the gravity principle, manual dredging intensity is greatly replaced or relieved, and the integrated high-pressure anti-blocking sucking, flushing and digging dredging equipment is suitable for mechanized dredging o f different working conditions of medium and small river channels.

Description

technical field [0001] The invention relates to underwater dredging mechanical equipment, which belongs to the technical field of excavation or dredging of IPC classification E02F5 / 00 water conservancy dredging projects, and in particular relates to integrated high-pressure anti-blocking suction scour dredging equipment. Background technique [0002] The dredging project of small and medium-sized rivers in cities and rural rivers generally intercepts both sides of the river, then pumps out the water, and excavates manually or with an excavator. Smell, great impact on the surrounding environment. [0003] At present, it is more and more difficult to rely on manual dredging, and it is urgent to realize the mechanization of dredging work. Large-scale dredging equipment and dredging vessels are basically built for large-scale dredging projects in ports, waterways or large rivers, and cannot enter small and medium-sized rivers for construction; if the hinged suction method is us...

AI Technical Summary

Problems solved by technology

[0012] The dredging of small and medium-sized rivers is still dominated by manual operation, and the dredging efficiency is low and the effect is not good. The disclosed construction machinery technology is far from meeting the actual needs. Due to the limitation of construction technology and equipment, it is necessary to use different auxiliary machinery for separate construction, which also restricts the progress and development of dredging engineering technology.
