Description

Technical Field

[0001] The utility model relates to the technical field of shell blowing machines, in particular to a vibration screening shell blowing machine. Background Art

[0002] The common method of separating grain grains and husks is usually to select by wind weight, that is, to blow air through the mixture of grain grains and husks through a fan. Since the husks are lighter in weight, they will produce a larger displacement under the action of wind, while the fuller grain grains will remain in place or produce a smaller displacement.

[0003] Traditional shell blowing machines utilize the above principle to blow air at the mixture of grain particles and husks that are falling or on a conveyor belt. The husks are greatly deflected and fall into different containers with the grain particles, thereby achieving separation and screening of grain particles and husks.

[0004] Traditional hull blowing machines are more suitable for separating a single type of husk. For a mixture of grain particles and husks of different sizes, the traditional hull blowing machines have poor separation effect because the larger husks and smaller grain particles have similar weights.

[0005] Based on this, the applicant proposed a vibration screening shell blowing machine to solve the above technical problems. Utility Model Content

[0033] A large-particle grain recovery plate 6 and a husk recovery plate 8 are arranged at the lower side of the large-particle separation chamber 13, and the husk recovery plate 8 is located on the side of the large-particle grain recovery plate 6 away from the fan 4. A small-particle grain recovery plate 7 is arranged at the lower side of the small-particle separation chamber 16, and the husk recovery plate 8 is arranged below the small-particle grain recovery plate 7.
