Fruit classifier

Abstract

The invention relates to early-stage processing machinery of fruits, in particular relating to a fruit classifier for classifying dry and fresh fruits such as red dates, walnut seeds, apples and the like. The overall unit comprises an adjustable speed motor, rollers, a friction wheel, a drive shaft I, a drive shaft II, a track, a conveyer belt, a feeding hopper, a discharge hole, an engine body and the like. One part of power is transmitted to the drive shaft I welded with a spiral track by chains, and the other part of power is transmitted to the drive shaft II capable of driving the rollers to rotate, clearance variation of the rollers is jointly completed by synchronous rotation of the two drive shafts, and the spacing size of the track is determined according to the requirements of the shape size and classifying of fruits. When in operation, fruits of which the shape size is smaller than the spacing between two rollers are separated from the clearance of the rollers and fall off on the conveyer belt which are divided into a plurality of outlets by clapboards according to the classifying requirements, and the separated fruits are discharged from the outlets so as to complete the classifying operation. The fruit classifier in the invention can classify fruits in various grades, has low fruit damaging rate, safe and convenient use and wide application range, and can classify the fruits into various grades according to requirements.

Description

(1) Technical field [0001] The invention belongs to fruit primary processing machinery, in particular to a kind of dry and fresh fruit grading machine, such as red dates, walnuts, apples and other dried and fresh fruits. (2) Technical background [0002] At present, there are three main classification techniques used: one is a circular hole sieve classification device, in the process of classification, sometimes the phenomenon of dried fruit clogging the screen hole, especially when a large amount of dried fruit is fed; the other is a flat vibrating screen The grading device has a poor grading effect; the other is a grid roller grading device, which has a high fruit damage rate. (3) Contents of the invention [0003] The object of the present invention is to propose a fruit grader driven by a motor and achieve the purpose of grade by changing the distance between the rollers. Grading of different kinds of fruits can be achieved by replacing the shafts with welded tracks. ...

Problems solved by technology

[0002] At present, there are mainly three kinds of grading technologies used: one is the circular hole sieve grading device, in the process of grading, sometimes the phenomenon of dried fruit clogging the sieve hole, especially when a large amount of dried fruit is fed; the other is the plane vibrating screen The grading device has poor grading effect; the other is the grid roller grading device, and the fruit damage rate is high
