Water-filtering sand dredging hopper for hanging type sand dredger

Abstract

The invention discloses a water-filtering sand dredging hopper for a hanging type sand dredger. The water-filtering sand dredging hopper comprises two half hopper bodies, four connection rods, a power connector and L-shaped anti-blocking plates. One ends of the two half hopper bodies are rotationally connected through a rotary shaft to form a whole hopper body with an upward opening. The first ends of the four connection rods are rotationally connected with half hopper bodies respectively, and the second ends of the four connection rods are rotationally connected with the power connector. A rotary plate is arranged on the rotary shaft and connected with the power connector through a steel wire rope. Each half hopper body comprises a bottom plate, a side plate, a front plate and a rear plate. A plurality of water filtering holes are formed in each bottom plate. One end of each anti-blocking plate is fixedly connected with the corresponding connection rods connected with the corresponding half hopper body. A plurality of desanding columns corresponding to the water filtering holes are arranged on the inner sides of the anti-blocking plates. According to the water-filtering sand dredging hopper, the multiple water filtering holes are formed in the bottom plates of the half hopper bodies of the sand dredging hopper, water in sand can be effectively and preliminarily filtered during sand dredging, and the phenomenon that the water filtering holes are blocked by sand and consequently water drainage is hampered can be effectively avoided through the desanding columns corresponding to the water filtering holes.

Description

technical field [0001] The invention relates to a sand mining bucket, in particular to a water filtering sand mining bucket of a suspended sand mining ship. Background technique [0002] Sand dredger, as the name suggests, is a sand and gravel mining tool, mostly used for mobile operations. Generally speaking, for sand mining, the use of sand is different, and the form of excavation is also different. For fine sand, sand suction is mostly used, while for coarse sand, chain bucket or hanging sand mining ships are mostly used. Among them, the position of the chain bucket sand mining ship is relatively fixed when it is working, the moving range is small, and the moving speed is also slow. , Move up and down fast, swing big left and right. The hanging type is basically the same as the sand suction type, but the activity of sand mining is slightly slower than the sand suction type, and the range is slightly smaller. Among them, the sand mining bucket in the hanging sand minin...

AI Technical Summary

Problems solved by technology

Among them, the sand bucket in the hanging sand mining ship is the main operating equipment, but generally the water content in the sand excavated from the river bottom is relatively high

The traditional sand mining bucket cannot carry out preliminary treatment on it
