Description

Seed screening device

Technical Field

The utility model relates to the technical field of agriculture, in particular to a seed screening device.

Background

The principle of the seed selecting device is to select seeds by using brine, namely, seeds are placed in brine with a certain concentration, and good seeds and bad seeds are separated by using buoyancy. The buoyancy of brine is greater than that of fresh water, and some non-filled seeds can be floated. For example, the salt water of wheat seeds is prepared by mixing salt water to a density of (1.16-1.2). Times.10.3 kg/m.sup.3. Wheat is placed in such salt water, good seeds having a density exceeding 1.2.103 kg/m.sup.3 are submerged in the water, and bad seeds having a density of less than (1.16-1.2). Times.10.sup.3 kg/m.sup.3 are floated in the salt water because they are subjected to a buoyancy less than their gravity, so that the good seeds are easily separated.

Salt water seed selection is a skillful seed selection method invented by ancient Chinese laborers. Seeds of various crops have a certain density. Wheat seeds grown very full, densities exceeding 1.2X10A 3kg/m3, rice seeds grown very full, densities exceeding 1.1X10A 3kg/m3, and densities of both shrunken and angiosperm Decay being much less than the density of filled seeds. The seed density of each crop is different, and the salt water concentration used should also be different. For example, the density of mung bean seeds is small, and the density of the brine used for selecting mung bean seeds is 1.1X10-3 kg/m-3. The method is used for selecting seeds, the concentration of the brine is preferably measured by a densitometer, if the densitometer is not used, the dissolved brine can be scooped out of a bowl, then a spoon of the selected seeds is put in, if the seeds are all submerged, the brine is too light, the salt should be continuously added, if most of the seeds float on the water surface, the brine is too strong, and the brine should be diluted by adding water until most of the seeds are inclined at the bottom of the bowl. The traditional seed selecting equipment needs to manually collect floating bad seeds or overflow bad seeds at the upper part from an overflow port by adopting a method of continuously injecting saline water, the manual collection efficiency is low, and the overflow method needs a large amount of saline water, which is not beneficial to improving economic benefit.
