Abstract

The invention discloses a method for separating vegetables and fruits, and the device. The vegetables of fruits are put on two parallel groups of circular grading sticks. There sets a grading stick of another group in the middle of the every two grading sticks of one group, every stick moves synchronously. When every stick is moving synchronously, one group of sticks moves flatly the other group of sticks move with n angle to plane. In the moving course, the gap between two sticks will increase step by step, thus the vegetables or fruits of correspondent size will fall through the gap, so it realizes the separation. The invention has advantages of high separation efficiency, regulable separation size, and it doesn't damnify the vegetable and fruits.

Description

The method and apparatus of sorting vegetable and fruit

Technical field:

The present invention relates to a kind of method and apparatus of sorting vegetable and fruit size, belong to vegetables and sorted fruits technical field.

Background technology:

At present, the method of sorting vegetables or fruit size generally all is to adopt the method for fixed mould sorting in the prior art, promptly produce the mould of corresponding different size according to the size of the vegetables of required sorting or fruit, then vegetables or fruit have been set the mould of different size size respectively by these, like this can with vegetables or fruit in accordance with regulations size sort out, the sorting technology of this fixed mould formula in the prior art, though have simple in structure, easy to operate advantage, but but exist inefficiency, can not carry out the adjustment of sorting specification as required, and when sorting easy shortcoming such as damage vegetables and fruits.Therefore existing vegetable and fruit sorting technology still is not ideal enough.

Summary of the invention:

The objective of the invention is: the method and apparatus that provides a kind of efficiency of separation height, sorting size can regulate and when the sorting vegetables and fruits, not damage the sorting vegetable and fruit of vegetables and fruits arbitrarily, to overcome the deficiencies in the prior art.

The present invention is achieved in that the method for sorting vegetable and fruit of the present invention is: it is placed on vegetables or fruit on two groups of circular grading sticks that are parallel to each other, and make a circular grading stick that is arranged with another group between per two circular grading sticks of one group of circular grading stick in parallel, make every circular grading stick of two groups of circular grading sticks all make same moved further, when all circular grading sticks are done with moved further, one group of circular grading stick is moved horizontally, make another organize the angular movement of circular grading stick work from the horizontal by α, the number of degrees of α are 2～40 degree, like this in the process that two groups of circular grading sticks are done to move, the spacing in the bar shaped gap in two groups of circular grading sticks between the adjacent circular grading stick will progressively increase, thereby the vegetables of corresponding size or fruit are leaked down from the bar shaped gap between this adjacent circular grading stick and be sorted out; When two groups of circular grading sticks are done with moved further, every circular grading stick is rotated around its axis.

The device of sorting vegetable and fruit of the present invention is: it comprises frame (1) and driving motor (2), end in frame (1) is equipped with power transmission shaft (3), the other end in frame (1) is equipped with two horizontal accessory drive sprocket wheels (4) and four chain stripe pitch adjustment sprocket wheels (5), four accessory drive sprocket wheels (6) and four chain tensioning pulleys (7) also are housed in the below of frame (1), four rotating sprockets (8) are housed on power transmission shaft (3), four driving chains (9) are enclosed within four drive sprockets (8) respectively, two horizontal accessory drive sprocket wheels (4), two chain stripe pitch are adjusted sprocket wheel (5), on four accessory drive sprocket wheels (6) and four chain tensioning pulleys (7), going up the parallel circular grading stick (10) of a group leader that is equipped with near two driving chains (9) of frame (1) two outer side edges, and two other chain stripe pitch is adjusted sprocket wheel (5) and is pressed in respectively on these two driving chains (9), go up the parallel short circular grading stick (11) of another group that is equipped with at other two driving chains (9), the every Long Circle grading stick (10) or the short circular grading stick (11) that are installed between the driving chain (9) all can rotate around himself axis, and all be parallel to each other between Long Circle grading stick (10) and the short circular grading stick (11), and between per two Long Circle grading sticks (10), be arranged with the circular grading stick of weak point (11) of another group in parallel, be provided with several culls side by side in the below of the upper strata Long Circle grading stick (10) at frame (1) medium position place and short circular grading stick (11) and send conveyer belt (12); Both sides in the below of upper strata Long Circle grading stick (10) and short circular grading stick (11) all are respectively equipped with movable friction rail (13), can control that movable friction rail (13) contacts with Long Circle grading stick (10) or with short circular grading stick (11) or the operating grip (14) that separates is connected on frame (1) and the movable friction rail (13).

Owing to adopted technique scheme, the present invention compared with prior art, the present invention has vegetables and fruits can be regulated and do not damaged to efficiency of separation height, sorting size arbitrarily when the sorting vegetables and fruits advantage.Use when of the present invention, can be according to the concrete needs of sorting vegetables or fruit, its angle of direction of motion each other when adjusting sprocket wheels (5) and regulate two groups of circular grading sticks and move by four chain stripe pitch, thus reach the purpose of sorting gap length between the circular grading stick of any adjustment.Because the present invention can be according to the characteristics of vegetables and fruits in the process of sorting vegetables and fruits, make vegetables and fruits when moving along with circular grading stick, can drive its vegetables and fruits by the rotation of circular grading stick rotates, thereby or circular grading stick is not rotated make a vegetables and fruits oblong grading stick to move together and does not rotate, so just can reduce or prevent when sorting damage to vegetables and fruits.When the circular grading stick of needs rotates, only need by operating grip (14) movable friction rail (13) is contacted with Long Circle grading stick (10) or with lacking circular grading stick (11), these circular grading sticks will be under the effect of movable friction rail (13) in the process that moves and rotate like this.The present invention is applicable to that the vegetable and fruit to shapes such as circle, ellipse, oblateness, Long Circle, tapers carries out sorting, and can carry out sorting to the fruit that has carpopodium or fruit leaf, and the present invention is adapted to avoid the vegetable and fruit that bumps and carry out sorting fresh and tender especially.
