Description
Technical field
The utility model is related to sweet potato seedling harvesting technical field, more specifically to a kind of sweet potato seedling cropping knife.
Background technology
Sweet potato seedling is in dense growth, therefore the harvesting of sweet potato seedling can only be by manually carrying out.Sweet potato seedling is growing to a fixed length
It could be gathered in, and also to be carried out " staying root " during harvesting after degree.In order to ensure that harvested sweet potato seedling possesses certain survival
Rate, the sweet potato seedling length of harvesting should exceed 200mm, and " staying root " refers to that harvested sweet potato seedling is still emerged soil 20mm, so
It just can guarantee that harvested sweet potato seedling remains to continued growth, and the two measurement of lengths are all workman now is rule of thumb entering
Row range estimation, precision is poor, easily causes and (influence survival rate) is just gathered in less than length and " staying root " length is too short (influences sweet
The continued growth of potato seedling growth).Current sweet potato seedling harvesting tool is scissors or cutter, and each workman will carry out 8000 in one day substantially
The blade of the harvesting of sweet potato seedling, scissors and cutter will be passivated, it is necessary to carry out sharpening or more renew in use for some time
Scissors and cutter, this has had a strong impact on harvesting efficiency, and it using scissors is even more to make the hand of workman dog-tired to be by it.Except this it
Outside, because sweet potato seedling is in dense growth, when cutting seedling, blade easily causes to scratch to the sweet potato seedling of surrounding, so as to influence it to grow.
