Stemming manufacturing device for underground blasting of coal mine

The stemming manufacturing device comprises a bottom plate, a three-phase asynchronous motor is fixedly arranged on the upper surface of the bottom plate, a three-phase asynchronous motor main shaft is movably arranged in the three-phase asynchronous motor, a rotating shaft is fixedly arranged at the tail end of the three-phase asynchronous motor main shaft, and a machining box is fixedly arranged on the surface of the rotating shaft. A spiral stirring block is arranged on the surface of the rotating shaft, a first bevel gear is fixedly arranged on the surface of the rotating shaft, a second bevel gear is meshed with the surface of the first bevel gear and movably arranged on the lower wall of the supporting flat plate, a lead screw shaft is fixedly arranged in the center of the second bevel gear, and a pressing plate is meshed with the surface of the lead screw shaft. According to the stemming production device, stemming is produced when the motor drives the spiral block to move, the funnel is extruded throu
