Background technique

Jujube is one of the main fruits in China, and the cultivated area of jujube trees in my country accounts for 99% of the total cultivated area in the world. However, harvesting jujube requires a large amount of labor, accounting for more than 50% of the total labor in jujube production. At present, there are few varieties of jujube picking machines on the market, most of which are manual, and most of them are relatively cumbersome, unable to make adaptive adjustments to branches of different sizes, and the picking efficiency is low. The jujubes fall directly on the ground during picking, which not only damages the appearance of the jujubes, but also needs to be collected again. At the same time, jujube picking machines cannot screen and grade the picked jujubes according to their size.

Therefore, it is necessary to provide a jujube picking machine, which can make adaptive adjustments for branches of different sizes during the picking process, and can directly collect the picked dates and complete preliminary screening and grading according to the size of the dates, thereby improving picking efficiency.
