Description

Technical Field

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

[0002] Seeds are selected before planting. Screening out bad or underdeveloped seeds can ensure survival rate and thus increase yield. Salt water seed selection is a clever method of seed selection. The seeds of various crops have a certain density. Full seeds have a higher density, while shriveled or insect-damaged seeds have a much lower density than full seeds. That is, in the prepared salt water, good seeds will sink to the bottom, and bad seeds will float on the surface of the salt water. This principle is used to screen seeds.

[0003] At present, traditional agricultural planting seed selection devices put seeds into prepared salt water when selecting seeds. Good seeds will sink to the bottom, and bad seeds will float on the surface of the salt water. The bad seeds floating on the surface of the salt water are fished out and discarded, and the good seeds are fished out for use. However, when selecting seeds through salt water, it is necessary to stop putting seeds into the salt water when the seeds are fished out, and then separate the seeds. The seed selection efficiency is low and the seed selection time is long. Utility Model Content
