Sugarcane seedling planting machine with centralizer

The invention discloses a sugarcane seedling planting machine with a centralizer. The sugarcane seedling planting machine comprises a transverse beam frame, a tractor, a planting machine and a furrowing machine. The planting machine comprises a planting machine assembly, the centralizer which is used for keeping the planting machine horizontal is further arranged beside the planting machine, the planting machine assembly is connected with the centralizer by rocker arms which constantly keep horizontal, the centralizer comprises a fixing plate, a centralizing ring, rail support wheels and a centralizing support arm, the fixing plate can be exactly matched with the inner-diameter side of the centralizing ring, the rail support wheels are mounted at two ends of the fixing plate, fulcrums can be formed, and the centralizing ring can be supported by the fulcrums when rotating around the center of the fixing plate. The sugarcane seedling planting machine has the advantages that problems of complicated structure and high cost of an existing centralizer of an existing planting machine can be solved, the structure of the centralizer of the planting machine is improved, and accordingly the centralizer is low in cost and is simple and practical.
