Fruit sorting machine

Abstract

The invention provides a fruit sorting machine, which comprises a machine frame, a motor and a fruit sorting device, wherein the fruit sorting device comprises a plurality of groups of screw rod-shaped screening rollers in parallel arrangement; each group of screening rollers comprise two rotating rollers (4); end parts of the rotating rollers (4) are linked with an output shaft of the motor through a transmission device; the diameter (d) of screw threads from the beginning segment to the tail segment on the each group of rotating rollers (4) changes from small to big; the diameter (d) of the screw threads of the beginning segment is adapted to the outer diameter of small fruit of fruit needed to be sorted; and a sorted fruit receiving device is arranged right below the rotating rollers (4). The fruit sorting machine has the advantages of not only being suitable for fruit with larger outer diameters, but also being more suitable for fruit with smaller outer diameters; as the fruit screening aperture of the sorting device can be adjusted, threaded holes of the rotating rollers can be designed based on the aperture of larger fruit when larger fruit is sorted, and is designed based on the aperture of smaller fruit when the smaller fruit is sorted.

Description

technical field [0001] The invention relates to a machine belonging to the technical field of machinery, in particular to a fruit sorting machine. Background technique [0002] An existing patent No. CN200520125934.4, a Chinese utility model patent titled "Fruit Sorting Machine", discloses a structure, which includes a control mechanism, a frame, a motor, a motor and a reducer are installed on the frame Direct connection, the output shaft of the reducer is connected with the fruit conveying and grading device through the transmission device, and there are at least two grade collecting buckets. The utility model has the beneficial effects of simple structure, low cost, economical and practical, simple operation and good grade selection effect. But its disadvantage is that this selection machine is only suitable for fruits with larger outer diameters, such as apples, pears and other fruits, but it is not suitable for the selection of fruits with smaller diameters such as red ...

Problems solved by technology

But its disadvantage is that this selection machine is only suitable for fruits with larger outer diameters, such as apples, pears and other fruits, but it is not suitable for the selection of fruits with smaller diameters such as red bayberry, lychee, and longan with smaller outer diameters. Its scope of use is relatively narrow, so its structure needs to be improved
