The invention further provides a grading and picking method applied to the device. The device is convenient to carry, a worker is free of moving the device and placing blueberries in a bent manner, force is saved, picking efficiency is improved, and the picking cost is lowered; the blueberries are divided into three grades according to specifications and defects, the post grading and screening are omitted, and treatment cost is reduced.

Description

technical field [0001] The invention relates to a grading and picking device, in particular to a portable grading and picking device for blueberries and a picking and grading method thereof. Background technique [0002] At present, blueberry picking mainly uses plastic baskets of different specifications. During the picking process, the plastic baskets are placed directly on the ground, and the pickers move the plastic baskets while picking blueberries. The defect of this picking method is: (1) the plastic basket is inconvenient to carry and needs to be moved frequently, and the picking personnel need to lean over and put the blueberry fruit to the picking basket, which reduces the picking speed, increases the picking cost, and consumes the picking personnel's time. (2) Place the plastic basket directly on the ground, which does not meet the food safety requirements; (3) Place the picked blueberries directly in the plastic basket, which belongs to mixed-grade picking, which...

Problems solved by technology

The defect of this picking method is: (1) the plastic basket is inconvenient to carry and needs to be moved frequently, and the picking personnel need to lean over and put the blueberry fruit to the picking basket, which reduces the picking speed, increases the picking cost, and consumes the picking personnel's time. (2) Place the plastic basket directly on the ground, which does not meet the food safety requirements; (3) Place the picked blueberries directly in the plastic basket, which belongs to mixed-grade picking, which requires manual or machine grading again. Cause a certain degree of damage to the blueberry fruit, affect the fresh food quality and storage period of the blueberry fruit, and increase the processing cost
