Description

  The present invention relates to a sugarcane planting machine used for planting stalk-like sugarcane seedlings in a planting ditch of a field while traveling in a field.

  Sugar cane is planted in the field twice a year in spring and summer (spring planted and summer planted). As preparation work for sugarcane, as preparation work, cultivate the field with a farming tractor, grind the soil finely using a rotary, level the ground and dig the ditch, and then cut the stem-like sugarcane cut into 20-30 cm for seedling In the ditch, lay down side by side at predetermined intervals, finally cover soil and squeeze, and finish the planting work.

  In recent years, mechanization has progressed by labor saving of work, efficiency improvement, etc., and a farmer who mounts a planting work machine (planter) directly on the rear of a farming tractor and machine-plants sugar cane stem for seedling is increasing. A typical example is towing the rear planting machine with a farming tractor, crushing soil with a rotary and digging the planting gutter (plant gutter), and immediately thereafter, the stalks inserted into the hopper of the planting machine -Shaped sugarcane seedling is dropped into a ditch, and soil covering and crushing are performed with a soil covering plate and a pressure roller at the rear. Fertilizers are usually applied to the ditch at the same time as planting, and herbicide is applied.

  As a planting work machine of this type, a device equipped with a crush rotor and a lidger, a back cover plate and a pressure roller (Patent Document 1), a blade and a pressure roller, and a hopper and a guide duct for dropping a groove There is known an apparatus (Patent Document 2) provided with a conveyor for guiding sugar cane for seedlings.
