Description

technical field

[0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical weeding mechanism between corn seedlings. Background technique

[0002] In recent years, mechanical weeding has gradually attracted people's attention due to its economical and environmental protection characteristics. The key to mechanical weeding is crop weeding between seedlings. Most of the existing weeding machines for weeding between seedlings are traditional comb-toothed and shovel-type, that is, weeding between seedlings is carried out by one or several groups of rotating shovels or combs. Traditional machines have a high rate of damage to seedlings and high power consumption, making it difficult to meet the development requirements of today's precision agriculture. In view of the above problems, the applicant has invented a lateral shrinkage intertillage and weeding unit, which can meet the requirements of precise weeding between seedlings of corn crops in nor...
