First of all,it instructions the economic value of , it introduces the present situation of our garlic cultivation and garlic seed drill need to solve the , it determined using artificial auxiliary directional way to realize the garlic tooth tip up. In turn scoop metering plate, directional device using artificial auxiliary orientation, Stand straight body uses a funnel, the grave institutions is the duck including the opener, covering and suppress sees were into the box after classcation. Device to scoop out the seeds scooped up one by one. Seeds reach directional device after the tail again fall by gravity into the funnel of stand straight body, realize the real tooth through seed stand straight body pointed straight at set up, the seed into the duck mouth the addition to the garlic seed drill directional need artificial auxiliary, other institutions fully automated, high efficiency, high standing straight, making the output of garlic, garlic planting mechanization was realized.
