The 1JSM-320 self balancing spring toothed paddy field burying machine adopts Japan's advanced dual axis burying technology. The burying machine structure adopts a front axle beating and rear axle burying working mode. The burying operation uses a high-strength spring toothed grass pressing device to actively bury the straw evenly below 8 cm in the mud, avoiding straw floating and affecting the transplanting operation of the rice transplanter, reducing the process of grass harvesting, and the fertility generated by straw decay is closer to the roots of crops, which facilitates the gradual absorption of crops and improves the yield of the operation.
