Description

Flat Fritillary Harvester

Technical field:

The invention relates to the technical field of agricultural machinery, in particular to a flat fritillary harvester.

Background technique:

Harvesting fritillary fritillary is a time-consuming and labor-intensive job, and the harvest is extremely time-sensitive. Almost all production areas are concentrated in June-July, and it is in the rainy season. Flat fritillary that is too late to harvest will rot in the ground. When harvesting flat fritillary, a lot of labor is employed. The tools used are picks, shovels, dustpans, sieves, rakes, etc. During the operation, first, use a shovel to pinch the top soil of the flat fritillary ridge to one side, and then use a rake and a pick to pick up the flat fritillary soil to a simple screening device. During the screening process, many flat fritillary roots are clogged. The sieving net has low screening efficiency, and one person must use the sieving net to sieve flat fritillary soil each time. According to its size, flat fritillary needs to be sieved several times through sieves of different sizes before it can meet the requirements. Therefore, collecting flat fritillary is a time-consuming and labor-intensive operation. There are few literatures and reports on the harvesting machinery of Fritillaria in China, and there are only potato, peanut, garlic, beet, Pinellia, Yuanhu, Nanxing and other crop harvesters that can be used for reference, but these machines are not suitable for harvesting Fritillaria There are two reasons for this: 1) Small potato, peanut, garlic, and sugar beet harvesters, due to the large digging depth and separation size (>20mm) and harvesting in opposite rows, are suitable for high planting density and small tubers (<20mm) ) is not suitable for harvesting of Fritillaria; 2) The tubers of Yuanhu and Pinellia are similar in size and shape, but the planting environment and harvesting methods are different, so they are not suitable for harvesting of Fritillaria. The development of special flat fritillary harvesting machinery is an inevitable trend to promote the large-scale cultivation of flat fritillary.
