A fully automatic high-efficiency sand mining device for underwater screening

Abstract

The invention provides a full-automatic efficient sand extraction device employing underwater screening. The full-automatic efficient sand extraction device employing underwater screening comprises a water storing and washing device, a lifting and purifying mechanism, a screening frame, a sand box, a sand extraction pipe and a sand extraction pump, wherein the water storing and washing device comprises a water channel; the water channel is reversibly arranged on the water surface; the lifting and purifying mechanism comprises a grid plate strip; the screening frame is arranged on the sand box; the grid plate strip is arranged at the lower part of the screening frame; the sand box is buried into a riverway; the upper surface of the sand box is flush with the riverway; one end of the sand extraction pipe passes through the sand box; and the other end is connected with the sand extraction pump. The full-automatic efficient sand extraction device employing underwater screening can be widely applied to sand extraction operations of a small brook, a diversion canal and the like, and does not need other power except for the power required by the sand extraction pump; through ingenious and reasonable mechanism arrangement, automatic sundries cleaning when extracting sand is achieved, so that manpower and material resources are greatly reduced; efficient, energy-saving and all-weather automatic sand extraction is really achieved; the brook and the canal are not destroyed; and the full-automatic efficient sand extraction device has great promotion and application value.

Description

technical field [0001] The invention relates to a sand mining device, in particular to a fully automatic high-efficiency sand mining device for underwater sieving. Background technique [0002] At present, sand mining is basically prohibited or restricted in main rivers all over the country, and the elevation of rivers is a real problem. To solve this problem, the only way to solve this problem is to start with source control. [0003] It is a feasible way to collect sediment or tailings from small tributaries of rivers and rural ditches in various places to reduce the flow of water and soil into the main river and comprehensively utilize sand and stone. At present, there are generally two methods for collecting sediment, which can be roughly divided into two types: one is manual water pumping, that is, relying on manpower to hold the sand pumping pipe to pump sand, or using a sand pump to suck sand. Due to the complicated river course, weeds, branches, gravel There are man...

Problems solved by technology

At present, there are generally two methods for collecting sediment, which can be roughly divided into two types: one is manual water pumping, that is, relying on manpower to hold the sand pumping pipe to pump sand, or using a sand pump to suck sand. Due to the complicated river course, weeds, branches, gravel There are many sundries, and the water pump head is often blocked. Therefore, no matter it is hot or cold, the sundries must be manually lowered into the water to clean up the sundries, which is labor-intensive and expensive; Loaded into the car together and transported to the screening point for screening, the cost is also high
