The invention discloses an electric pug mill for making a soil sample of specific
moisture content. The electric pug mill comprises a base, a supporting rod, a supporting cross bar, a
mixing tank, a mixing head and a motor. According to the device, the mixing head adopts the principle of an egg whisk, one end is fixed, and the other end is movable, so that the contact area between the water and soil the sample is enlarged, and the soil sample and water can be fully contacted; and therefore, uniform mixing is realized, the bending degree of steel bars between flanges can be adjusted, and soil samples at different positions are further adjusted and mixed. By taking
electric power as the power, the conditions that the force is non-uniform during manual mixing, the made soil samples are non-uniform due to spilling of
distilled water and soil particle aggregate appears can be avoided, time and labor can be saved, and losses of the water and soil samples during mixing are reduced, so that the made soil samples meet test standards; a test
jar is adopted at the bottom, so that muddy water is avoided from splashing in the mixing process; and the
mixing tank is fixed on a supporting seat, sothat the
mixing tank can be avoided from sliding down, and the position can be optionally moved.
