Abstract
The utility model relates to the field of sample preparation equipment, in particular to a screening device. The screening device comprises a base, a screening frame, a screening rolling plate and a reciprocating drive mechanism. The screening frame which is provided with rotary shafts at two ends respectively is arranged on the base in a sliding mode. Two ends of the screening rolling plate are wound on the rotary shafts at two ends of the screening frame respectively, a plurality of screening areas are distributed on the screening rolling plate, and a plurality of screening holes of certain specifications are arranged in the screening areas. The reciprocating drive mechanism is connected with the screening frame, so that the screening frame can slide back and forth on the base. According to the screening device, continuous screening areas with the screening holes of different specifications are arranged on the screening rolling plate, so that various screening requirements can be met rapidly by rotating the screening rolling plate; and a screening machine is not needed to be disassembled, and accordingly, the operation efficiency is improved and the service life of the screening machine is increased while the labor is saved.
Description
Technical field
