The invention discloses a dual-gravity fine-screening sieve for grain. The dual-gravity fine-screening sieve for grain comprises a support provided with wheels. A primary gravity sieve and a secondary gravity sieve are fixedly arranged on the support. A high-frequency vibrating sieve is connected between the primary gravity sieve and the secondary gravity sieve. A high-frequency vibrating motor is mounted on the side wall of the high-frequency vibrating sieve. The primary gravity sieve and the secondary gravity sieve each comprise a gravity sieve body and a gravity fan, wherein connecting rods are hinged to the front end and the rear end of the gravity sieve body correspondingly, the other end of each connecting rod is hinged to the support, and a gravity rocker is hinged to the side wall of the gravity sieve body. According to the dual-gravity fine-screening sieve for grain, the high-frequency vibrating sieve is additionally arranged for transition, grain is screened and graded through the vibrating sieve after being gravity-screened for the first time, then the grain is gravity-screened for the second time for removing residual molded grains and dust, the screening effect is improved, and the grain screening precision is improved; and meanwhile, environmental friendless is achieved, and pollution is avoided.
Description
technical field [0001] The invention relates to the field of grain screening, in particular to a grain selection screen with double specific gravity. Background technique [0002] The specific gravity machine is a kind of mechanical equipment for the screening and selection of seeds. It can select qualified and excellent seeds according to the differences in shape, size, specific gravity, surface characteristics and aerodynamic characteristics of seeds and impurities. At the same time, the specific gravity machine can also be used to select and grade the seeds, and select the strong, full and vigorous seeds. Therefore, the gravity machine replaces the traditional low-efficiency operation mode of manual seed selection and manual screening. [0003] However, in the existing specific gravity machine, during screening and seed selection, the internal screening device needs to reciprocate, which drives the specific gravity machine to sway to a certain extent. Therefore, the spe...
