Seed soaking device for agricultural seedling raising

Abstract

The invention relates to a seed soaking device for agricultural seedling raising, and belongs to the technical field of agricultural breeding equipment. The seed soaking device comprises a soaking liquid barrel, a seed grain barrel and a stirring device, the soaking liquid barrel is provided with a seed soaking cavity, the stirring device comprises a first flushing rod, a fixing rod, transmissionrods, a driving rod and an air cylinder, and the first flushing rod is fixedly connected to the lower end face of the fixing rod; the transmission rods are evenly and fixedly connected to the side wall of the fixing rod, the driving rod is fixedly connected to the lower end faces of the transmission rods, a piston rod of the air cylinder is fixedly connected with the lower end face of the drivingrod, and the lower end of the first flushing rod is fixedly connected with a first rubber plug; and the side wall of the soaking liquid barrel is provided with a first flushing cavity, a first spraying hole communicated with the first flushing cavity is formed in the side wall of the seed soaking cavity, and the first rubber plug at the lower end of the first flushing rod is slidably connected with the first flushing cavity. In the process of spraying soaking liquid, the soaking liquid impacts seed grains from bottom to top, and the seed grains are turned over under the impact, so that a stirring effect is achieved, and the phenomenon that a large number of broken grains are caused by directly stirring the seed grains by using a stirring shaft is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding equipment, in particular to an agricultural seed soaking device for raising seedlings. Background technique [0002] The purpose of soaking seeds is to promote early germination of seeds, and it can also kill some insect eggs and viruses. The purpose of seed soaking is to make the seed grain absorb water faster and reach the water content that can germinate normally. The moisture content of dried seeds is usually below 15%, the physiological activity is very weak, and they are in a dormant state. After the seeds absorb water, the seed coat swells and softens, the oxygen dissolved in water enters the cells along with the water, and the enzymes in the seeds also start to activate. Due to the action of enzymes, the respiration of the embryo is enhanced, and the insoluble substances stored in the endosperm are gradually transformed into soluble substances, which are transported to the ...
