Description

Air-aspiration type daylily harvesting device

Technical Field

The utility model relates to the field of agricultural machinery, in particular to an air-suction type daylily harvesting device.

Background

The harvesting time of the day lily has special requirements, if the time is equal to the time after flowering, the harvesting yield can be reduced, the quality can be deteriorated, and the nutritional value can be reduced. If the harvesting is too early, the buds are not grown, the components are light, the quality is low, and the nutritional value is also insufficient. Thus, the optimal harvesting time of day lily is 2 hours before flowering, and the harvesting period is relatively concentrated. Because the physiological characteristics of day lily, the time for harvesting day lily is mostly in the early morning, the harvesting period is 6-8 months, the time for harvesting is rainy, the air is moist, the working time and the working environment for manual harvesting are poor, the body and the harvesting efficiency of a harvesting worker can be influenced, the harvesting period is overlapped with the time for harvesting summer grains, and the shortage of labor resources for harvesting day lily causes the increase of the harvesting cost of day lily. In addition, fresh daylily contains a large amount of colchicine, and human body contact for a long time during harvesting operation can cause certain corrosiveness to skin.

Because of the special requirements of daylily harvesting, the current daylily harvesting work can only be carried out manually, and no mechanized and intelligent harvesting equipment exists. However, the manual harvesting is heavy, the labor intensity is high, the efficiency is low, and the planting cost is greatly increased. Along with the continuous increase of the planting scale of day lily, the problem of mechanical harvesting is also needed to be solved.

Based on the above, in order to improve the daylily harvesting efficiency and reduce the damage to the harvesting personnel, it is necessary to invent an air-suction type daylily harvesting device, which can greatly reduce the contact to the daylily during the operation of the harvesting personnel, realize the mechanized harvesting of the daylily, and has important significance for improving the comprehensive mechanized level of the daylily harvesting and promoting the development of the daylily industry.
