Description

Technical Field

[0001] The present invention relates to the field of agricultural machinery, and particularly to a parallel clamping type automatic mulberry leaf picking device. Background Art

[0002] At present, the picking of mulberry leaves mainly relies on manual operation, which has problems such as high labor intensity, large time cost, and low picking efficiency. Therefore, the automatic harvesting of mulberry leaves is particularly important, and improving the efficiency and quality of mulberry leaf picking has become a problem that needs to be solved in the current sericulture industry.

[0003] The Chinese invention patent application with the publication number CN117999956B discloses a cutting type mulberry leaf picking device. Its moving knife can rotate relative to the fixed knife at a certain angle to cut the mulberry leaf petiole, and the mulberry leaves fall into the collecting devices on both sides. However, there are still the following defects in the use process: (1) During the lifting process of the lifting platform, there will be blank areas where the mulberry leaves are not cut when the moving knife rotates and cuts, resulting in incomplete picking of the mulberry leaves. (2) The height of the front end of the middle rod is inconsistent with that of the left and right rods, and the cutting inlet and outlet of the mulberry branches are too small. When the mulberry branches have not entered the cutting channel, they will be clamped by the middle rod and the left and right rods and bent. Summary of the Invention
