Gunpowder mixer

The invention discloses a gunpowder mixer which comprises a frame and multiple layers of steel tubes, wherein two ends of each steel tube are fixedly connected to the inner side of the frame; the steel tubes are arranged in parallel along the horizontal direction; the steel tubes are arranged along the vertical direction in a staggered manner; support legs are arranged at the lower part of the frame; an elastic device sleeves each support leg; and one side of the outer side of the frame is fixedly connected with a connection device. The gunpowder mixer is simple in structure and ingenious in design; in the mixing process, the heat energy is not easy to gather; the generated heat energy is easy to disperse; the mixing condition of the gunpowder is convenient to observe; measures can be timely taken if a combustion phenomenon appears; the safety performance is high; mixing is even; powder aggregation and blockage are effectively avoided; and time and labor are saved by mechanical vibration mixing. 种火药混合器，包括框架和复
