Abstract
A rotary sampling apparatus for powdered or granular materials wherein the materials are automatically sampled and pneumatically transported to a predetermined place. A first variant of the present invention is of a rod-like type which has a rod-like body having a measuring table. The rod-like type rotary sampling apparatus is designed to be inserted into a bed of powdered or granular materials through an external wall of a storage container such as a hopper dryer. A second variant of the present invention is of a mounted type rotary sampling apparatus with a measuring table and the apparatus is designed to be incorporated into a mounting pedestal provided with the storage container. In both variants of the present invention, the measuring table is rotated by a rotary actuator, a measuring hole of the measuring table is placed at a material sampling position, and powdered or granular materials are sampled and filled in the measuring hole. The hole of the measuring table is rotated into a material discharge position and the materials are forcedly pneumatically discharged through a discharge passage by feeding a pressurized gas.
