Description

Technical Field

[0001] The utility model relates to the technical field of seed selection, in particular to a seed selection device. Background Art

[0002] The quality of seeds directly affects the yield. Seeds with full grains, good uniformity, high integrity, high germination rate and strong germination potential are the prerequisites for fully realizing the yield potential of the variety. Therefore, seeds should be carefully selected before sowing to ensure that the uniformity, integrity and fullness of the seeds meet the requirements.

[0003] At present, seed selection devices are commonly used to select seeds.

[0004] The prior art publication number is CN218775175U, which is a corn seed processing selection device, including a box body, a feeding barrel fixed on the top of the box body, a discharge pipe connected between the bottom end of the feeding barrel and the top of the box body, a feed hopper connected to the top of the feeding barrel, a rotating shaft rotatably connected to the side wall of one side of the feeding barrel, and a spiral feeding blade tightly sleeved on the outer wall of the rotating shaft. Its miscellaneous shell dust is separated and transported to a collection box under the action of wind. An air outlet is opened on the side wall of the collection box, which is conducive to air circulation. However, the dust separated from the seeds is also easily discharged through the air outlet, polluting the surrounding environment of the equipment. At the same time, no dust adsorption mechanism is installed at its feed hopper. If manual feeding or other feeding equipment that cannot close the feed hopper is used for feeding, dust will overflow when the seeds fall into the feed hopper, which also pollutes the surrounding environment of the equipment. For this reason, a seed selection device is proposed. Utility Model Content
