Technical Field

[0001] This invention belongs to the field of agricultural machinery, and specifically relates to a garlic harvester. Background Technology

[0002] Currently, the level of mechanization in garlic harvesting is low. Most garlic harvesters use simple digging devices, requiring manual labor for tasks such as picking, cutting stalks, and trimming roots. This is labor-intensive and inefficient. A small number of large garlic harvesters are used, but the harvest quality is poor, requiring further manual processing. They also have poor adaptability to different plots, such as those with intercropping, and their functions are incomplete, only capable of digging and cutting stalks, which cannot adequately meet production requirements. Summary of the Invention

Working Principle: The tractor drives the casters of the transmission support mechanism to move, and the hydraulic jack controls the lifting and lowering of the harvesting unit. The grooved wheel on the tractor axle is connected to the grooved wheel on the transmission support mechanism via a V-belt. The grooved wheel is connected to the drive sprocket on the same shaft. The drive sprocket is sequentially connected to the sprocket on the drive shaft and the double-row sprocket on the unit support shaft via a chain. The double-row sprocket drives the harvesting unit to work. The digging shovels at the front of the low-position shovel and the high-position shovel dig up the garlic. The low-position shovel and the high-position shovel support the garlic stalk clamp and the garlic head clamp. The foot plate in the garlic stalk clamp supports the garlic stalk clamp and slides on the ground. The guide rod in the garlic stalk clamp gathers the garlic stalks into the garlic stalk clamp. With the support of the garlic stalk clamp chain, the garlic stalks are pulled up and move upward along the garlic stalk clamp. After being cleaned by the cleaning brush, they enter the separation box. In the separation box, the garlic head clamp sprocket guides the garlic head end into the garlic head clamp. After moving a certain distance, the garlic head is pressed against the bottom of the garlic head clamp. The cutter on the garlic clamp cuts off the garlic stem, which moves along the clamp and is then thrown out. The garlic head moves along the clamp to the cutting blade, where it is clamped and cut by a disc blade and a blade. After being cut, the garlic head moves along the clamp into the garlic hopper, then into the garlic tube, and finally into the garlic collection box. When the garlic head in the collection box reaches a certain amount, the collection box automatically flips over and dumps the garlic into a pile. The low-position harvesting unit and the high-position harvesting unit are alternately set on the unit support shaft. Adjacent separation boxes are staggered vertically. The width of the shaft support plate and the high shaft support plate is equal to the minimum width between the digging shovels. The distance between the harvesting units is adjustable. The groove on the top plate of the harvesting unit is locked onto the lifting angle iron to lift the harvesting unit. The lifted harvesting unit stops working. The width between the digging shovels of the adjacent harvesting units of the lifted harvesting unit increases. The harvester can adapt to narrow and wide ridge widths as well as intercropping ridge widths. The digging depth of the digging shovel can be adjusted by adjusting the fixed position of the holes on the shovel positioning plate and the adjusting plate. 8. Compared with the prior art, the present invention has the following beneficial effects: it realizes integrated operation of digging, pulling up, cleaning, cutting stalks, trimming roots and collecting; it has wide adaptability, can adjust the width between harvesting units, adapt to narrow ridges, wide ridges and intercropping plots, can adjust the digging depth of the shovel, adapt to plots with deeper and shallower planting; it has fast working speed, high efficiency and good effect, which will greatly promote the development of the garlic industry.
