Description

Technical Field

[0001] The present invention belongs to the field of plant breeding equipment, and particularly relates to a wheat seed screening device. Background Art

[0002] Wheat is a general term for plants of the genus Triticum, which is a grass widely cultivated around the world. It originated in the Fertile Crescent region. Wheat is the second most produced food crop in the world after corn. Wheat is of utmost importance in China's food system and is a commodity grain with relatively rich nutrition and high economic value. Wheat grains contain rich starch, more protein, a small amount of fat, as well as various mineral elements and vitamin B.

[0003] During the wheat harvest season, generally, workers use a sieve bucket to sort wheat seeds into good and bad ones, separating the poor-quality seeds. However, when there is a large amount of wheat, multiple workers are required for sorting. During the sorting process, repeated up-and-down inversion actions are needed, which easily makes workers tired. Long-term work will cause a decline in workers' attention and requires rest time, resulting in low work efficiency in the process of sorting wheat seeds. Therefore, a wheat seed screening device is needed. Summary of the Invention

[0004] In view of the problems of the prior art, the technical solution adopted in this application is as follows: A wheat seed screening device includes: a base, a screening frame, a seed transportation mechanism, screening holes, a mounting backboard, and a conveyor belt. The screening frame is mounted on the base. The screening frame is circular, and the surface of the screening frame is provided with a plurality of screening holes arranged in an array. The diameter of the screening holes is the same as that of the wheat seeds to be screened. A mounting backboard is provided on the side of the screening frame, and a seed conveying mechanism is mounted at the center of the mounting backboard. A conveyor belt is provided on the seed conveying mechanism for transporting wheat seeds.

[0005] The screening frame is circular, and the central rotating shaft of the screening frame is connected to a motor. The screening frame rotates driven by the motor, and during the rotation process, the seeds inside are screened. The seeds are separated through the screening holes on the screening frame. A blower is also provided inside the screening frame to screen out the lighter poor-quality seeds, and finally, the smaller poor-quality seeds are selected through the screening holes; the screening frame is used to screen wheat seeds with gradually increasing volumes. The screening frame includes a first inclined plate, a second inclined plate, a first screening rod, a second screening rod, and a push rod. The first inclined plate and the second inclined plate are connected by a connecting plate, and the connecting plate is fixed to the first support plate.

[0006] The spacing between the first inclined plate and the second inclined plate gradually decreases from top to bottom, and a first gap matching the smaller particles is left between the lower ends of the first inclined plate and the second inclined plate. One end of the first sieve bar is fixed to the first inclined plate, and one end of the second sieve bar is fixed to the second inclined plate. A second gap is left between the first sieve bar and the second sieve bar, and the second gap gradually decreases from left to right, so that seeds with full particles can fall down from the left ends of the first sieve bar and the second sieve bar. The push rod can move back and forth left and right along the first gap and the second gap. When the push rod moves to the left, it can push the seeds with full particles between the first and second inclined plates toward the first and second sieve bars, and can move the seeds with full particles on the first and second sieve bars.

[0007] The seed conveying mechanism includes a conveyor belt disposed within a screen box. Main rollers 1 and 2 are rotatably connected to the inner wall of the screen box via a fixed axis. Two auxiliary rollers are also rotatably connected to the inner wall of the screen box via a fixed axis. These two auxiliary rollers are connected via a conveyor belt transmission. A hopper is fixed to the inner wall of the screen box, equipped with a vibrating mechanism, and main roller 1 is in transmission connection with the vibrating mechanism. A dust removal assembly is also disposed on the inner wall of the screen box, and main roller 1 is in transmission connection with the vibrating mechanism. This seed production conveying vibrating screen and impurity removal device achieves efficient seed screening and impurity removal while simultaneously transporting seeds horizontally.

[0008] Compared with the prior art, the advantages and positive effects of the present invention are: The present invention provides a wheat seed screening device, comprising: a base, a screening frame, a seed transport mechanism, screening holes, a mounting back plate and a conveyor belt. The screening frame is mounted on the base, the screening frame is in a circular shape, and a plurality of screening holes arranged in an array are provided on the surface of the screening frame. The diameter of the screening holes is consistent with the wheat seeds to be screened. By using this method, the wheat seeds are thrown up by a circular motion, and then lighter and inferior seeds are screened out by a fan. Finally, smaller inferior seeds are screened out by the screening frame, thereby achieving a fully automated and manpower-saving effect, thereby greatly improving work efficiency.
