Description
Technical field
The present invention relates to lotus leaf harvesting device and its control method, belong to agricultural mechanical field.
Background technology
Lotus leaf can be widely applied in functional food, health food and beverage, and because acquisition cost is improved and is packed for
Amount is powerful, and lotus leaf price is difficult to adjust back.In recent years, market demand was increasing, and the lotus leaf dried can be processed into pollution-free food
Packaging bag, thus the raw materials for production of a variety of medicines such as it or slimming drugs driven price rapidly to rise.
But the mode drawback of traditional lotus leaf harvesting is a lot, is safety problem first：One side people gather in lotus in ship
Leaf can bending go to break lotus leaf bar and easily fall into korneforos, if being also possible to because the imprudence of rocking of ship hurts oneself with reaping hook, people
Lower water harvesting, which may also be slided into, rubs wound；Followed by efficiency：At least two people (control ships, receipts on one ship during hand harvest
Cut)；Because lotus leaf grows and its mixed and disorderly, hand harvest's speed is slow, wastes time and energy, and the artificial lotus leaf cut out is also irregular.With
The understanding that people to lotus leaf intrinsic value is gradually apparent, and the demand of lotus leaf surges, and existing harvesting mode, which is added, works into
This, causes it to hold at high price, is unfavorable for the development of lotus leaf related industry.
