AI Technical Summary

Technical Problem

Planting elephant grass in slag heaps in high-altitude and cold regions is time-consuming and labor-intensive, with a low survival rate and serious threats from harmful organisms in the soil. The existing planting methods are inefficient.

Method used

An elephant grass planting device for the remediation of slag heaps in high-altitude and cold regions is adopted, which includes an L-shaped support frame, a vertical cylinder, planting components and a motor-driven hollow rod. Through rotary excavation and electric shock treatment of slag heaps, combined with rooting powder and beneficial bacterial solution, the device achieves efficient planting of elephant grass and soil purification.

Benefits of technology

It improved the survival rate of elephant grass, reduced the labor intensity during the planting process, enhanced the ecological restoration effect of the slag dump, and reduced the threat of harmful organisms by treating the slag with electricity.

Abstract

This invention discloses a method and apparatus for planting elephant grass in the remediation of slag heaps in high-altitude and cold regions, belonging to the field of slag heap remediation technology. The elephant grass planting apparatus for slag heap remediation in high-altitude and cold regions includes an L-shaped support frame with a material box fixedly installed on it. The material box contains elephant grass stems (2-3 sections). A vertical cylinder is fixedly installed on the outside of the L-shaped support frame via a moving mechanism. A discharge rod is fixedly installed on one side of the vertical cylinder, with one end of the discharge rod connected to the inside of the vertical cylinder and the other end of the discharge rod fixedly connected to the material box via a feeding pipe. The apparatus also includes a planting component, which is installed inside the vertical cylinder. A striking plate inside the planting component reciprocates to strike a force-bearing plate, generating an electric current on the surface of the force-bearing plate, which is transmitted to a conductive plate via a wire. The slag heap, after being subjected to strong electric shock, generates corresponding high temperatures, causing harmful organisms to die and causing chemical substances in the soil to undergo oxidation, reduction, and decomposition reactions, thus achieving good ecological restoration of the slag heap.
