Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a self-propelled root-cutting leafy vegetable harvester. Background Art

[0002] In the production process of vegetables, the harvesting process accounts for a large proportion. At the same time, this process is also a time-consuming and labor-intensive link, requiring a lot of time and energy. At present, leafy vegetables such as Shanghai green and spinach planted in the field are mainly harvested under the soil by hand, which has high labor intensity, low work efficiency, and poor quality of leafy vegetable harvesting. In some places, vegetable harvesters are used for operations. At present, the vegetable harvesters on the market are mainly imported, mainly leafy and head vegetable harvesters, and most of them are harvested on the soil. Although many domestic units have developed vegetable harvesters, most of them are harvested on the soil. However, most of the leafy vegetable planting areas in Gansu are in hilly and mountainous areas, and a small amount is in river valley depressions or slopes. The terrain is mainly small plots and terraces, which is not conducive to large-scale mechanized planting and harvesting operations. The introduction of mainstream leafy vegetable harvesting equipment at home and abroad faces the problem of acclimatization. Therefore, leaf harvesting is still basically done by manual picking, which has high labor intensity and low production efficiency. In recent years, labor costs have shown an upward trend year by year, and even labor shortages have occurred in local production areas, seriously affecting the increase in production and income of growers.
