Abstract

The invention discloses a coal mine exploitation screening device for facilitating uniform stirring. The coal mine exploitation screening device comprises a main shell, a servo motor, a positive and negative motor and a collecting trough; the main shell is internally provided with a sliding slot, the main shell is internally provided with a crushing barrel, a convex ring is fixedly connected to the middle portion of the outer side of the crushing barrel, an upper end cover is fixed to the left side of the main shell, the servo motor is fixedly mounted in the upper end cover, the lower end of amain shaft is fixedly mounted at the bottom of the crushing barrel, springs are arranged on the left and right sides of a screening plate, the right side of the screening plate is arranged in a sleeve, a steel rope is connected to the left side of the screening plate, the steel rope is arranged inside the springs, the other end of the steel rope penetrates through a left-side base to be connectedto a rotary disc, a fixing shaft is connected to the positive and negative motor, and the collecting trough is arranged at the bottom of the base. By means of the coal mine exploitation screening device for facilitating uniform stirring, the screening device moves left and right to enable coal mine on the screening plate to be separated faster, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a screening device for coal mining that is convenient for uniform stirring. 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 chosen to excavate coal by digging underground, which is called an underground coal mine. [0003] Existing coal mine mining needs to stir and beat the coal mine during screening so that the larger coal mine can be separated better, but the stirring and crushing effect of the existing stirring and crushing device is not good, and the coal mine cannot realize Stir evenly, and increase the difficulty of coal mine screening at the same time. Contents of the invention [0004] The purpose of the present invention is to provide a screening dev...
