Abstract

The invention provides a coal gangue crushing, ball-milling and grouting device. The coal gangue crushing, ball-milling and grouting device comprises a device shell, a lifting seat main body and a grouting pipe main body, wherein a discharging port is formed in the bottom of the device shell; the lifting seat main body is fixedly installed on the two sides of the outer wall of the device shell, and a supporting plate which is in contact with the ground is arranged at the bottom of the lifting seat main body; and the grouting pipe main body is detachably arranged at the bottom of the device shell, and the grouting pipe main body communicates with the discharging port of the device shell. According to the coal gangue crushing, ball-milling and grouting device, a second driving motor is arranged, when the second driving motor in an inner cavity of a motor box is started, the second driving motor can enable a first rotating rod and a second rotating rod to rotate through a first horizontal gear and a second horizontal gear, movable crushing teeth are driven to be matched with fixed crushing teeth to crush coal gangue materials, so that the problem that when large coal gangue blocks are stirred, the stirring is insufficient, and meanwhile, blockage is prone to occur during discharging and subsequent grouting is solved, and the stabilizing effect is improved.

Description

technical field [0001] The invention relates to the technical field of grouting devices, in particular to a coal gangue crushing ball mill grouting device. Background technique [0002] Coal gangue grouting device refers to a new technology that performs grouting to reduce settlement in the coal seam overlying rock separation layer, inhibits overlying rock movement, reduces surface subsidence, and is suitable for safe mining of "three-down" coal pressing. It is fully studied Under the premise of the failure mechanism of the overlying rock layer of the coal seam, the separation layer space during the overlying rock damage process is used to inject gangue slurry, fly ash slurry and other filling materials into the separation layer space through ground drilling to realize the suppression of the grouting layer. The overlying rock is further destroyed, slowing down the propagation speed of the overlying rock moving to the upper surface, controlling the movement of the rock layer ...
