Technical Field

[0001] The invention relates to the technical field of picking equipment, in particular to a backpack-type litsea cubeba picking device. Background Art

[0002] Litsea cubeba is a precious woody aromatic oil tree species with high economic value. Its roots, stems, leaves and fruits all contain aromatic oils, which can be processed into raw materials for the production of medicines, foods, cosmetics and high-end spices, etc. It is an important mountain resource. However, most of Litsea cubeba are planted in low mountains and hills, and its harvesting is mainly based on cutting branches and trees, relying entirely on manual picking, which is labor-intensive and labor-costly. This leads to a large amount of waste of Litsea cubeba due to unharvested or even unharvested. Therefore, the research and development of automatic picking tools for Litsea cubeba has positive and important practical significance for the production and development of Litsea cubeba.

[0003] The tree of Litsea cubeba is tall and spread out, with long branches and thorns, and the fruits are small and easy to be damaged. At the same time, the agronomic requirements for harvesting Litsea cubeba are very high. It is necessary not to damage the leaves, buds and branches, and it must be harvested in time. As a result, the currently commonly used automatic harvesting methods such as high-branch shearing, mechanical vibration, and negative pressure absorption have problems in harvesting Litsea cubeba, such as low picking efficiency, easy damage to the fruit, and large size of the machinery that is difficult to use in hilly and mountainous areas.

[0004] In view of this, in the field of Litsea cubeba harvesting, there is an urgent need for a lightweight Litsea cubeba fresh fruit picking device that is easy to carry and operate, and can pick and collect the Litsea cubeba fresh fruit without damaging the plant. Summary of the invention
