High-phreatic-water-level area soil reclamation device and method

Abstract

The invention discloses a high-phreatic-water-level area soil reclamation device which comprises a feeding box, a crushing box, a sliding block, a conveying structure and a transmission frame. The feeding box is of a rectangular box-shaped structure, a cylinder-shaped containing cavity is formed in the middle section of the feeding box, and a plurality of sets of discharging openings are formed inthe bottom of the containing cavity at equal intervals; a plurality of sets of second crushing cutters are fixedly arranged in the containing cavity at equal intervals, a rotating motor is installedin the middle section of one side edge of the feeding box, the front end of a motor shaft of the rotating motor extends into the containing cavity and is fixedly provided with a rotating roller, a conveying structure is installed on one side edge of the crushing box, and the bottommost portion of a filter screen communicates with the conveying structure; and a slag outlet is formed in the bottom of the crushing box, four sets of supporting legs are vertically fixed to the four corners of the bottom of the crushing box, a transmission frame is arranged among the four sets of supporting legs, aconveying belt is arranged on the transmission frame, and an adsorption structure is arranged at the middle section of the transmission frame.

Description

technical field [0001] The invention belongs to the technical field of soil reclamation, and in particular relates to a soil reclamation device in a high water potential area, and also relates to a soil reclamation method in a high water potential area. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. When the distance between the coal seam and the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine. In recent years, coal mine waste such as coal gangue has been used for filling and reclamation of coal mining subsidence areas, which can alleviate a large number of coal mine abandonmen...

AI Technical Summary

Problems solved by technology

[0003] The existing soil reclamation devices in areas with high water level cannot crush the gangue to a specified diameter and backfill it, which will easily cause large gaps between the gangue and cause serious water and soil loss
