Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a lettuce harvesting and packaging vehicle. Background Art

[0002] Lettuce is a common vegetable. Its growth characteristics are "early growth and late aging", that is, lettuce grows faster, but its growth period is relatively short, so it needs to be harvested in time. At present, lettuce production is almost entirely manual. In the harvesting process, the time is tight and the task is heavy, the labor intensity is high, and the labor efficiency is low, which is the biggest bottleneck of the whole mechanized production. There are few trials and demonstrations of mechanized harvesting of lettuce in China. my country usually harvests lettuce by hand. Although some lettuce harvesters have appeared on the market, such as single-row side-mounted lettuce harvesters and medium-sized lettuce harvesters, there are generally some limitations. The former is too large and can only be used in large lettuce production bases. It cannot enter the lettuce fields of ordinary farmers, and their labor intensity cannot be improved. Although the latter solves the problem of excessive volume, its function is too single. It can only harvest lettuce, but cannot solve the problem of subsequent packaging.

[0003] The patent document with publication number CN117322239A discloses a fully automatic photovoltaic charging new energy lettuce harvesting, leaf removal and bundling machine. The utility model can realize the simultaneous harvesting, leaf removal and bundling of lettuce. Each group of harvesting, conveying and leaf removal modules can automatically track in real time according to the width of the lettuce ridge, and the rotating cutting knife can also adjust the height above the ground in real time according to the changes in the ground. However, the bundling machine lacks a component for adjusting the posture of the falling lettuce, which will affect the bundling effect when multiple lettuces are not parallel.

[0004] The patent document with publication number CN118020486A discloses an efficient lettuce harvesting device with a positioning harvesting structure. The utility model can automatically navigate and locate, plan the path and position the lettuce by setting a rotating mechanism, a cutting mechanism and a grabbing mechanism. However, the device uses the grabbing mechanism to trap a single lettuce and then cut it, which is inefficient and lacks an automatic packaging component. Utility Model Content
