Description

Technical Field

[0001] The utility model relates to the technical field of agricultural tools, in particular to an electric seedling thinning device for corn planting. Background Art

[0002] The amount of corn planted in rural my country is very large and its distribution is also relatively wide. In order to ensure the germination rate, more seeds are usually sown during sowing. In this way, more seedlings will grow in most seed holes. In order not to affect the normal growth of corn, it is generally necessary to remove the excess corn seedlings according to the specific situation.

[0003] The Chinese patent document with publication number CN201639923U discloses a corn seedling thinning device. The device uses a connecting rod structure to make up for the distance between the human hand and the corn seedling, so that the thinning operation does not require bending over, which greatly reduces the labor intensity.

[0004] However, the original equipment was unable to completely remove the roots of the corn seedlings, resulting in the tops of some corn seedlings being removed. The remaining corn roots in the field would absorb some nutrients, which required improvement. In addition, the eradicated corn roots could not be replanted, resulting in a waste of nutrients for nourishing the corn roots. Utility Model Content
