A kind of automatic fruit grading equipment
Technical field
The utility model relates to a kind of automatic fruit grading equipment, particularly a kind of equipment that tangerine class fruit is carried out classification.
Background technology
Multiple import or homemade fruit grading equipment are arranged in the market, and these equipment mainly are applicable to pachydermia mandarin orange orange and apple etc., but are not suitable for the granulated sugar tangerine substantially.
Aspect hierarchical form, it is several that the hierarchical form of existing device mainly contains cylinder aperture formula, roll shaft clearance-type, electronic weighing type, image is handled formula.The principle of drum-type aperture formula classification adopts multistage cylinder rotation carrying out classification with holes exactly, and citrus is driven the upset operation, and the fruit in different fruits footpath sees through the cylinder aperture and separates, and this hierarchical approaches very easily causes the damage of granulated sugar tangerine.The classification of roll shaft clearance-type mainly is applicable to ellipse or nearly spherical fruit, and granulated sugar kob typ shape is oblate, adopts this kind hierarchical approaches tandem extremely serious.It is less to the damage of granulated sugar tangerine that electronic weighing type and image are handled the formula classification, but these two kinds of hierarchical approaches will detect single fruit, output be with individual/hour be unit, be applicable to all bigger fruit of navel orange equal-volume weight, granulated sugar tangerine single fruit weight is little, then output is little to adopt this mode classification, and efficient is low.
