This invention discloses a wide-narrow row
transplanting device for *
Houttuynia cordata* seedlings with a telescopic adjustable spacing structure. It includes two vertical beams arranged symmetrically on the left and right sides, with a support frame installed between them.
Transplanting cylinders are located on both sides of the inner cavity of the support frame. Each
transplanting cylinder consists of two parts: an arc-shaped reinforcing plate is installed on the upper part of the cylinder, and a limiting slider is installed on the front side. This invention utilizes a
drive motor to rotate a bidirectional screw, which engages with an adjusting seat threadedly. This causes the limiting slider to slide laterally within a limiting groove, thereby moving the
transplanting cylinder laterally. This allows for flexible adjustment of the wide and narrow row spacing, adapting to the transplanting needs of *
Houttuynia cordata* seedlings of different sizes, offering strong versatility. Furthermore, the transplanting cylinder has a detachable structure, allowing for quick
assembly and disassembly via connecting ears and bolts. This facilitates the placement of seedlings and removal after transplanting, preventing damage to the
seedling roots during transplanting and improving the
survival rate.
