Description

This invention relates to the field of agriculture.

A device for sorting fruits is known, comprising two pairs of upper and lower pulleys with grooves for endless transporting belts forming between the sorting cells and guide plates for the sorted fraction flj.

The disadvantage of this design is the incomplete passage of the fines through the lower branch.

The whole invention is to provide a complete passage of the sorted fraction.

This is accomplished by the fact that the grooves in the lower squares are placed so that each subsequent groove adjoins directly before the front and is grouped into separate blocks, and an elastic screen is installed directly above the belts of each block.

FIG. 1 shows a device for sorting fruits, the total BtUj in FIG. 2 the same, side view.

Claims (1)

The device for sorting fruits contains infinite conveying elements 1 with upper 2 and lower 3 branches, upper 4 and lower 5 pulleys with blocks 6 of guide grooves 7 for conveying elements 1 and trays 8 9. Grooves 7 on blocks 6 lower cheeks 5 are made on minimum distance from one another. Thus, the adjacent transport elements 1 of the lower branch form groups of parallel elements located at a minimum distance from one another, and the extreme transport elements of each group are located at the maximum possible distance from one another, forming passages between these groups. At 8TOM, the dimensions of the aisles significantly (by a factor of times) in the prime gap or, thus, the thickness of the grades of the sorted fraction. An elastic screen 10 is installed above each group of transporting elements in the passage area of the sorted fraction. The proposed device operates as follows. Fruits arrive at the upper branch of the endless conveying elements 1 in the direction of arrow A. Fruits from i-sorted fine fraction pass into the gaps between the conveying elements 1. At the same time, the devices intended for orientation of the fruits with respect to the calibrating gap are possible (not shown ). The fruits of the sorted fraction are guided by trays 8 and 9 or directly in the free fall into the passage zone formed by groups of adjacent transporting elements 1. The elastic screen 10 prevents the fruit from falling directly onto groups of adjacent transporting elements and deflects the fruit to the areas of passage of the sorted fraction. The arrangement of the guide grooves on the lower pulleys in blocks so that in each of the blocks the grooves are spaced at the minimum possible distance from one another, and an elastic screen is installed directly above each formed group of secondary transport elements of the lower branch, allowing for a full pass of the sorted fraction through the lower branch of the endless transporting elements. The technical and economic effect of the proposed device is created by eliminating the use of mechanical and Other means for ensuring the passage of the sorted fraction or its withdrawal from the machine cavity for sorting fruits, i.e., excluding the use of an outboard conveyor and agitator. Claims An apparatus for sorting fruits, comprising two pairs of upper and lower cheeks with grooves for infinite conveyor belts forming between the sorting cells and guide plates for the sorted fraction, characterized in that, with the aim of free removal of the sorted fraction, the grooves on the lower pulleys are placed so that each subsequent groove adjoins the previous one, and is grouped into separate blocks, and directly above the belts of each block is installed elastic screen.
