Single-row double-row dual-purpose tobacco stem drawing machine

The utility model discloses a single-row double-row dual-purpose tobacco stem drawing machine, which comprises a connecting frame and supporting frame bodies, wherein the connecting frame is connected with a power mechanical vehicle frame, and the supporting frame bodies symmetrically extend outwards from two sides of the connecting frame. A pair of chains driven by a power source to move oppositely is disposed on each supporting frame body, chain rails controlled by pressure springs are respectively arranged on the supporting frame bodies on adjacent sides of the chains, the connecting frame is a sleeve structure movably combined into a whole, and sleeves on the two sides of the connecting frame can be stretched and adjusted to adapt to different widths of tobacco rows. When the left side (or the right side) of the tobacco stem drawing machine is needed to work in a single row, the unused connecting sleeve on one side can be drawn from the connecting frame, and one pair of the chains are kept working, thereby realizing single-row stem drawing. As the stem drawing machine is flexible and convenient in operation and low in manufacturing cost, the stem drawing machine can be used to simultaneously achieve double-row stem drawing or single-row stem drawing, and can double working efficiency. Compared with a mode of drawing stems by manpower, the stem drawing machine has more increase in efficiency.
