The garlic seeder uses playback technology, first pressing the holes with a pressure cone according to the row spacing and pit 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 conical spiral seed guide tube with the root facing downwards and the teeth facing upwards, without tilting. The thresher must synchronize the pressure hole cone with the seed divider during the middle pressure process, and the lag time of the garlic cloves falling freely through the conical spiral seed guide tube allows the garlic cloves to enter the hole exactly. The diameter of the smooth inner hole in the conical spiral tube seeding tube of the garlic seeder is 10mm larger than the maximum size of the garlic cloves in order to allow the cloves to fall freely on the conical spiral tube and prevent them from biting the tube.
