Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural machinery field especially relates to a garlic harvester. BACKGROUND

[0002] In the field of agricultural machinery, the garlic harvester is used for harvesting garlic in agriculture, and the power part of the garlic harvester is usually provided with a tractor head to provide power for the whole garlic harvester, and the walking mechanism connected with the power part drives the garlic harvester to move. When the walking mechanism of the existing garlic harvester encounters uneven road surface, it will cause a certain impact on the garlic harvester, thereby affecting the harvesting work of garlic.

[0003] The existing garlic harvester with the connecting mode of the walking mechanism and the frame adopts movable connection. When encountering uneven road surface, the walking mechanism will be inclined to one side after being affected by the uneven road surface. However, since the walking mechanism with the power part is relatively heavy, the walking mechanism cannot restore balance by itself. When this situation occurs, the operator can only stop the garlic harvesting work and manually level the vehicle body, which greatly reduces the efficiency of garlic harvesting and increases the physical labor of the operator. The existing garlic harvester with the connecting mode of the walking mechanism and the frame adopts fixed connection. When encountering uneven road surface, the walking mechanism will be inclined to one side after being affected by the uneven road surface. However, since the walking mechanism and the frame are fixedly connected, when the walking mechanism is inclined, the frame and the mechanism for harvesting garlic arranged on the frame will also be inclined, so that the mechanism for harvesting garlic is shallow on one side and deep on the other side. If the vehicle body is not leveled in time, the garlic on the shallow side will be damaged, and the garlic on the deep side will be deeper. Therefore, how to develop a new type of garlic harvester becomes a problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL
