Traditional artificial way of garlic harvest is digging, garlic harvesting and ripping, shipment, artificial results will be very tired, the efficiency is not high, the situation of the loss of garlic is very serious. And since the harvest of garlic is very seasonal, require short time of the harvesting, so the garlic mechanized harvesting is particularly important. Therefore, bined the garlic harvester has a structure, the design of a new type of self-propelled walking harvester for garlic. The machine of machinery including clamping garlic seedlings tool rod? the knife cut the seedling of garlic? digging shovel? transportation chain? collecting bag? etc. First of all, the use of high speed rotary tool cutting diameter of garlic, and the tool rod clamp the seedlings of garlic to remove it easily. Then garlic is digging up by Triangle-flat-shovel, garlic and soil be separated by the transport chain, the garlic is collecting mesh the bag of collection box. Design on the diesel engine provides ample power, using gear box reducer to slow the rotation speed, ensure t
