The Shandong garlic seeder adopts on-demand technology, first pressing the holes with a pressure cone according to the row spacing and nest spacing to form a certain size hole shaped cone hole. After selection, the garlic cloves fall freely through the seed divider and fall into the cone shaped spiral seed guide tube under the influence of the cone shaped spiral seed guide tube. The root of the garlic cloves that enter the soil is facing downwards and the teeth are facing upwards, and they fall into the cone hole hole without tilting. The pressure cone and seed divider of the Shandong garlic seeder must be synchronized during operation, and the lag time of the garlic cloves falling freely through the cone shaped spiral seed guide tube should be such that the garlic cloves can enter the hole exactly.
