Description

Seed sorting machine

Technical Field

The invention belongs to the technical field of agricultural machinery, and particularly discloses a seed sorter.

Background

The rice seeds are damaged by worms or are empty and shriveled, so that the germination of the seeds can be seriously influenced, the agricultural harvest is reduced, and therefore, before the seeds are sowed, workers need to select the seeds; in addition, the disease resistance of the seeds can be improved after the seeds are selected by saline water. At present, rice seed selection completely depends on manpower, the labor intensity of workers is high, and the seed selection efficiency is low.

In order to solve the technical problems, the chinese utility model patent with the publication number CN207138097U discloses a brine seed sorter, which comprises a seed sorting container and a brine storage container, wherein the brine storage container and the seed sorting container form a brine circulation system through a brine pipeline, and a brine switch valve is arranged at the outlet of the brine pipeline; the seed selection container is provided with a stirring device which is supported on the central axis of the seed selection container extending up and down and can rotate by taking the central axis of the seed selection container as the center; the stirring motor is positioned outside the seed selection container and is connected with the stirring device; the filtering device is a cavity arranged along the flow direction of the brine in the brine pipeline, and is supported and fixed on the seed selection container to separate the region in the seed selection container from the seed selection region; the seed inlet is arranged at the upper end of the seed selection container; the seed outlet is arranged at the bottom of the seed selection container and is provided with a valve; the solution port is arranged on the seed selection container and is provided with a solution switch valve; the supporting legs are arranged at the lower end of the seed selection container.

By adopting the technical scheme of the patent, the following problems can be caused that 1) a seed inlet is arranged at the upper end of a seed selection container, a seed outlet is arranged at the bottom of the seed selection container, the whole seed selection process can be completed only by the seeds after seed selection sinking to the bottom of the container from the upper end of the container, the seed selection speed is slow, and the seeds are contacted with saline water for too long time in the sinking process to cause damage to the surfaces of the seeds; 2) put into the seed selection container with the seed that worm-eaten or empty shriveled seed and the seed of quality preferred together, the seed that worm-eaten or empty shriveled seed can stop in the seed selection container upper end, the seed of quality preferred can sink gradually, the workman need wait for a period of time after, just can detach the worm-eaten or empty shriveled seed of container upper end, otherwise can miss the seed of quality preferred of container upper end and detach, but because the worm-eaten or empty shriveled seed of container upper end can absorb water gradually and sink, so the time that the workman waited is longer, can mix more worm-eaten or empty shriveled seed in the seed after the selection, in a word, the seed selection effect of the seed selection machine of above-mentioned patent is poor, can mix more worm-eaten or empty shriveled seed in the seed after the selection.
