Coal seam drilling and grouting device and using method thereof

The invention discloses a coal seam drilling and grouting device and a using method thereof. The coal seam drilling and grouting device comprises a base, and a push rod is fixed to the right end of the base through a screw; a mixing tank is fixed to the top of the base, a motor is fixed to the top of the mixing tank through a screw, the output end of the bottom of the motor is connected with the inner end of a rotating rod through a bevel gear set, the outer end of the rotating rod is connected to a support through a bearing, and the bottom of the support is fixed to the top of the mixing tank through a screw. And the outer end of the rotating rod extends into the storage tank to form a rotating mechanism. According to the coal seam drilling and grouting device and the using method thereof, a sealing plate is installed, a bevel gear set is driven to rotate through the output end of a motor, then the bevel gear set rotates to drive the sealing plate to rotate, and therefore quantitative feeding can be conducte
