Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a leek harvesting and bundling integrated machine. Background Technique

[0002] Leek, a perennial herb of the Allium genus in the Liliaceae family, has a delicious taste, a unique aroma, is rich in various nutrients, has high edible value, and is a convenient ingredient for frying and various side dishes. The seeds of leek can also be used as medicine, with the effects of warming and tonifying the liver and kidney, and strengthening yang and consolidating essence.

[0003] Since leeks grow for many years, they need to be harvested multiple times a year. The complete harvesting process includes leek cutting, laying, and bundling. When harvesting leeks, it is necessary to ensure that the roots and leaves of the leeks are not damaged. Large harvesters are often unable to perform the harvesting work. Therefore, for many years, leek harvesting in China has been mainly carried out manually, with low harvesting efficiency, and the income of vegetable farmers cannot increase. Moreover, vegetable farmers bend down to work for a long time, resulting in greater physical damage. Although there are existing push-type leek harvesters for auxiliary operations, most of them have a single function and lack a bundling function, and subsequent manual bundling operations are still required, which restricts the development of the leek industry. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a leek harvesting and bundling integrated machine, which includes a frame, a cutting mechanism, a conveying mechanism, a bunching mechanism, and a packaging mechanism.
