Tobacco planting device for determining plant spacing

The tobacco planting device structurally comprises side edge wheels, a middle rotating shaft and a pushing rod, the length of the middle rotating shaft is adjusted under the action of ruler distance holes in the outer side of an adjusting frame by pulling a telescopic arm, so that the distance between the side edge wheels on the two sides is increased, the side edge wheels can be adjusted according to the distance between the two ridges, and the holes can be punched in the two ridges; the fixed nut is rotated to loosen the sliding blocks to slide in the sliding groove according to the distance between punched holes, the distance between the sliding blocks is adjusted under the action of the scale block so as to achieve the purpose of adjusting the plant spacing, and the plant fixing cone and the punching cone can be replaced according to the threaded holes, so that the operation is simple and convenient. And then, a middle rotating shaft is pushed by a pushing rod, so that an inner rotating wheel drives an ou
