Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a hand-held chive harvesting equipment and an automatic box separation device suitable for island field operations. Background Art

[0002] Chives are a common condiment in my country and are in great demand. They are planted in many areas of my country. In 2022, the yield of chives per mu reached 2,000-3,500 kilograms. Because chives have well-developed branches and a large range, the branches are prone to lodging in the mature stage. After being dug out, the soil attached to its roots is difficult to remove, resulting in poor chive harvesting. At present, in my country's mechanized research on chive harvesting, harvesting is difficult, and the loss rate and soil adhesion rate are high. At present, the harvesting of chives in my country mainly relies on manual harvesting. After the chives are dug and pulled up manually, they are neatly laid out in the field and collected uniformly. This harvesting process is labor-intensive and has low harvesting efficiency.

[0003] In recent years, in order to solve the problems of high labor intensity and low harvesting efficiency of manual harvesting of chives, corresponding harvesting machinery has been developed. However, there are still deficiencies in the removal of soil at the roots of chives and the harvesting process. Most studies have shown that the method of harvesting chives is simply to shovel up the chives and spread them randomly in the field, which still requires manual picking and collection, which is difficult to meet the needs of modern agriculture.

[0004] At present, there are few reports on the research of hand-held chive harvesting equipment for island field operations. Chinese Patent No. CN116649073A discloses a self-propelled multi-row chive harvesting device and a control method thereof, which can loosen and separate chives from the soil, pull out the onion plants, transport them in an orderly manner, remove the soil from the roots and collect them in an orderly manner, and can also perform secondary soil removal, and can achieve neatly laid out harvesting of chives; Chinese Patent No. CN202310058118.9 discloses a chive harvester with a soil separation function and a control method, which can achieve the harvesting of chives separated from the soil, but the cleaning effect is not good, or the cleaning is not thorough. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a hand-held chive harvesting equipment and an automatic box sorting device suitable for island field operations. During transportation, the chives are rotated 90 degrees from a vertical state to facilitate the packing of the chives, and during the overall transportation process, a fine brush is provided to continuously scrub the soil at the roots of the chives to remove most of the soil at the roots.
