Technical Field

[0001] The utility model relates to the technical field of field tobacco plant root processing, in particular to a flue-cured tobacco root pulling device. Background Art

[0002] After the tobacco leaves of flue-cured tobacco are mature and harvested, only the straw at the roots of the tobacco plants remains in the field. In order to reduce the spread of tobacco diseases and facilitate tobacco planting next year, the straw at the roots of the tobacco plants must be removed in time. However, due to the developed underground root system of tobacco, manual tools are needed to remove the straw. Even if the fixed clamping rod at the end of a rod and the movable clamping rod at the end of the rod clamp the tobacco plant, and then the rod is pressed down, the support rod linked to the movable clamping rod is against the ground, and then the fixed clamping rod and the movable clamping rod moving upward cooperate to remove the tobacco plant. In this process, personnel need to use the strength of their arms to press down the rod, which has a high labor intensity. Therefore, it is necessary to design a flue-cured tobacco root pulling device that reduces the labor intensity. Utility Model Content
