Description

Lift roller shape-type grader

The present invention relates to a sorter for sorting potatoes or onions by size, and more particularly, to a lift roller type sorter capable of precisely sorting potatoes or onions without damage.

Fruits and vegetables such as onions, potatoes, tangerines, garlic, and the like are harvested and stored after being harvested because they are mixed with good and bad and sick. As the screening method, it can be divided into manpower screening which is directly sorted by man and by machine screen which is sorted by using mechanical device. In the past, the selection of manpower has become mainstream, but the number of companies that perform machine selection is increasing every year due to the reduction of the labor force in rural areas, satisfying the needs of consumers, and the increase of logistics costs. In other words, some storage companies and most packaging centers in mountainous regions purchase or consign fruits and vegetables from producers to carry out packaging work through machine selection.

The sorter can be divided into a weight sorter, an optical sorter and a shaped sorter. Shape sorter is sorted according to size and shape and has small size and weight deviation and low damage. It is onion, potato, garlic, citrus and other small sized fruits and vegetables used for sorting cherry tomatoes and bell peppers needed for mass processing. do.

Shaped sorting machines include screen-type perforated rotary drums and rotating belts, and inter-spacing and roller-gap sorting (also called "lifter shaped sorting machines"). The roller gap pass-through sorter is a sorter that sorts fruits and vegetables as the gap between two- and multi-chamber belts and rollers gradually widens. The fruits and vegetables are sorted by dropping fruits and vegetables smaller than the gap by supplying fruits and vegetables sequentially on the rollers. do.

11A and 11B, the pair of rollers 333 for sorting the fruits and vegetables 370 are diamond-shaped, and the gap formed by the rollers 333 is narrow, so that the gap between the rollers 333 is narrow. Overlapping fruits and vegetables 370 that can pass through may fail to pass through the gap.

Accordingly, it is an object of the present invention to provide a lift roller type sorter that can accurately sort without damaging fruits and vegetables.
