New green energy carry-scraper

Abstract

The invention discloses a new green energy carry-scraper and belongs to the technical field of underground mining. According to the new green energy carry-scraper, a battery device provides power fora microprocessor center through a direct-current power adapter, the battery device is connected with a switched reluctance drive (SRD) through a switch circuit, and the SRD is connected with a workingmechanism; the microprocessor center controls the switch circuit and the SRD; and a battery managing circuit receives the data of a battery pack, the microprocessor center reads the battery pack datareceived by the battery managing circuit, the battery pack data is displayed on a display screen, and the microprocessor center controls a battery charging mechanism to act. The new green energy carry-scraper has the beneficial effects of being simple in structure, high in stability, free of distance limitation and wide in view and cannot pollute the environment, meanwhile according to the new green energy carry-scraper system, the hydraulic loss can be reduced, the mechanical abrasion is reduced, the replacement period of hydraulic oil is prolonged, and the production cost is reduced.

Description

Problems solved by technology

[0003] Electric scrapers and diesel scrapers are widely used in underground mining. Electric scrapers have the characteristics of simple structure, simple operation, high work efficiency, simple maintenance, and no air pollution. However, the working radius is limited by cables. Generally no more than 90 meters, the high rate of cable damage leads to increased mining costs, and the cable box not only limits the field of view, but also causes the center of gravity to be too high, reducing the stability of the whole machine

Diesel scrapers have the characteristics of unlimited working distance and high working efficiency. However, the maintenance of diesel engines is cumbersome, the structure is complicated, and the exhaust emissions cause secondary pollution.

At the same time, the pressure of the oil pump is generally controlled by the relief valve of the traditional scraper. This method will cause hydraulic loss, increase mechanical wear, cause frequent hydraulic oil replacement cycles, and increase production costs.
