River bottom sand removing equipment for water conservancy project

Abstract

The invention discloses river bottom sand removing equipment for a water conservancy project. The river bottom sand removing equipment comprises an installation frame, a sand cylinder used for collecting gravel is fixed to the installation frame in a penetrating mode, and a bucket used for fishing the river bottom gravel is vertically and movably arranged on the front portion of the installation frame. An auger material conveying assembly used for conveying the gravel into the sand cylinder is installed below the installation frame, and the upper portion of the auger material conveying assembly fixedly communicates with a flat conveying piece. When a power structure works, the bucket is driven by an eccentric assembly to vertically move up and down in a reciprocating mode, the river bottomgravel can be fished and removed in cooperation with a continuously-walking sand fishing boat, and the fished gravel on the bucket is conveyed into the flat conveying piece through the sand conveyingassembly driven by the power structure when the bucket moves to the highest stroke point of the bucket; The sand is discharged into the auger material conveying assembly through the flat conveying piece, the power structure drives the auger material conveying assembly to convey the gravel into the sand cylinder, and finally the sand fishing, conveying and removing effects are achieved.

Description

technical field [0001] The invention relates to a river channel cleaning device, in particular to a river bottom sand cleaning device for water conservancy projects. Background technique [0002] The main function of the river course is drainage and navigation. If there is too much mud accumulation on the riverbed, the riverbed will be raised, which will affect the navigation and drainage capabilities. Therefore, every few years, some river courses need to be cleared. [0003] The cleaning operation is mainly sand cleaning operation, because the river channel is mainly composed of sand and gravel accumulation, which leads to the rise of the river water level. At present, the most commonly used river bottom sand cleaning equipment is mostly sand cleaning boats, but sand cleaning boats cannot realize automatic sand cleaning, and the use cost is very high. At the same time, the efficiency of traditional manual dredging is very low. [0004] Therefore, it is necessary to deve...
