During the rotary drum test, firstly, a charging basket is inserted and placed on a charging basket seat below a cone of a drum body at a vertical position, and then a guide table cylinder is lifted, so that the charging basket and the cone are closed in a involution manner; then, starting an indexing driving mechanism to enable the C-shaped overturning seat to rotate 180 degrees, and pouring materials in the charging basket into the drum body completely through the cone; then, the indexing driving mechanism drives the C-shaped overturning seat to reversely rotate by 90 degrees, and the rotating shaft of the drum body is positioned at the horizontal position; thereafter, the drum drive mechanism may be activated to perform the desired drum test. And after the test is finished, all the tested materials fall into the charging bucket through the operation opposite to the previous operation, the guide table cylinder is lowered, and the charging bucket is taken out for screening and weighing, so that result data can be obtained.

Therefore, the invention has the advantages of compact structure, no need of complex external auxiliary facilities, simple operation, high automation degree and no pollution to environment, and the whole drum test process runs in a sealed state, thereby avoiding serious pollution caused by material throwing, scattering and dust raising, and ensuring accurate test results.

The invention is further perfected that the plate chain at the periphery of the C-shaped overturning seat is meshed with a driving chain wheel, and the driving chain wheel is in transmission connection with the internal rotation motor of the underframe through a chain.

The invention is further perfected in that the driving sprocket is coaxial with the limit roller.

The invention is further perfected in that the slewing bearing is coaxial with a large gear which is meshed with a small gear driven by a drum motor arranged on the C-shaped turning seat.
