Abstract

The utility model discloses a roll shaft type fruit grader which comprises a frame rack, roll shafts and a fruit collecting mechanism, wherein the roll shafts are parallelly arranged on the rack at a certain interval, and the fruit collecting mechanism is arranged below the roll shafts; in addition, the surface of each roll shaft is provided with concave-convex positions at a certain interval, and the concave positions of adjacent roll shafts correspond so as to form a grading hole. The fruit grader disclosed by utility model is simple and reasonable in structure; the fruit grader has a limited grading effect, so that oblate fruits always are fed into the grading hole along the diameter direction to carry out grading, and therefore, influences caused by branches and leaves are decreased, a situation that fruits are damaged by clamping can be avoided, and the grading is smoother and more accurate, in such a way, the grading effect of oblate fruits, especially Shangtang oranges, is greatly improved.

Description

A kind of roll shaft formula fruit grader

Technical field

The utility model relates to the fruit grading technical field, relates in particular to a kind of roll shaft formula fruit grader that carries out classification according to the fruit size.

Background technology

The classification of fruit mainly contains dual mode: the one, carry out classification according to fruit weight, and the 2nd, carry out classification according to fruit size.Normally carry out classification for circle and spherical fruit according to size, this hierarchical approaches of prior art adopts rotary drum grader and floating roller grader to handle mostly at present, although the use of this kind equipment has improved classification efficiency owing to having replaced artificial work, but grading effect is unsatisfactory, for any of several broadleaf plants mandarin orange in oblate fruit such as the Citrus, Pon mandarin orange, tribute mandarin orange etc., especially the classification of granulated sugar tangerine is handled, and still exists following technological deficiency:

1, rotary drum grader is to utilize the perforate size to carry out classification; although being applicable to the classification of oblate fruit from structural principle handles; but because cedra fruits; especially granulated sugar tangerine; need the band branches and leaves to sell; and granulated sugar tangerine pericarp is thinner, thus the application cylinder grader when carrying out classification through regular meeting take place because stopping of branches and leaves and can't classification and folder rotten fruit, size scurry the phenomenon of level, practical application effect is bad.

2, floating roller grader is to utilize gap size to carry out classification, be that the classification roll shaft is by a pair of chain drive, just there is a roll shaft to float every one in the roll shaft, regulates the gap length of adjacent roll shaft by the high low amplitude of regulating the roll shaft that floats, to reach the purpose of fruit on the roll shaft being carried out classification.Floating roller grader is mainly used in the classification of spherical or ellipticity fruit, be applied to oblate fruit such as granulated sugar tangerine and can partly alleviate the problem of folder rotten fruit, but owing to be the granulated sugar tangerine of oblate shape, its diameter differs, difference is bigger, it is highly approaching that the words of the floating roller grader of employing need only flat position, just can enter in the identical rank, thereby cause classification inaccurate, it is more serious that size is scurried level.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reasonable, the smooth and easy roll shaft accurately of classification formula fruit grader, with the oblate fruit of effective raising, the especially grading effect of granulated sugar tangerine.

The purpose of this utility model is achieved by the following technical programs:

A kind of roll shaft formula fruit grader that the utility model provides comprises frame, roll shaft, fruit collecting mechanism; Described roll shaft is spacing row side by side and is located on the frame, and described fruit collecting mechanism is arranged on the below of roll shaft; In addition, the surface of described roll shaft is and is interval with concavo-convex position, and the recess between the described adjacent roll shaft is corresponding and constitute the classification hole.Recess on the utility model roll shaft, not only constitute the classification hole that fruit passes through, and has a position-limiting action, limit oblate fruit, especially granulated sugar tangerine all with diametric(al) the time by the classification hole, diameter to fruit also has effect of contraction, reduce the influence that branches and leaves bring so on the one hand, can avoid pressing from both sides rotten fruit and make classification more smooth and easy, also avoided size to scurry the phenomenon of level on the other hand.

In the such scheme, for further improving the position-limiting action of roll shaft, the recess of roll shaft described in the utility model is broken line shape.

Further, the width of recess is highly corresponding with the flat position of fruit on the roll shaft described in the utility model, establish to become spacing form row between described roll shaft, be that spacing between the roll shaft is corresponding with the diameter of oblate property fruit, make that fruit all is to carry out classification according to diameter, different roll shaft spacings is isolated the fruit of different-diameter size, makes classification more accurately smooth and easy.

The utlity model has following beneficial effect:

The utlity model has spacing grading, make oblate fruit enter the classification hole and carry out classification according to diametric(al) all the time, reduced the influence that branches and leaves bring, can avoid pressing from both sides rotten fruit and make classification more smooth and easy, classification is accurate, has greatly improved the grading effect of oblate fruit.

Description of drawings

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:

Fig. 1 is the schematic diagram of arranging of the utility model embodiment roll shaft;

Fig. 2 is the structural representation of the utility model embodiment roll shaft.

Among the figure: roll shaft 1, recess 11, classification hole 2, spacing L1, recess width L2, fruit 3.

The specific embodiment

Illustrated in figures 1 and 2 is a kind of roll shaft formula of the utility model fruit grader, comprises frame, roll shaft 1, fruit conveyor structure, fruit collecting mechanism.

As shown in Figure 1, roll shaft 1 is spacing row side by side and is located on the frame, be provided with to changing greatly by little according to the spacing L1 between the fruit throughput direction roll shaft 1, and the surface of roll shaft 1 is and is interval with concavo-convex position (see figure 2), recess 11 on the roll shaft is broken line shape, and its width L2 is highly corresponding with the flat position of fruit 3.Recess 11 between the adjacent roll shaft 1 is corresponding and constitute classification hole 2.The fruit collecting mechanism then is arranged on the below of roll shaft 1.

The prior art that can adopt the fruit conveyor structure realizes the transmission of fruit, as moving by drive unit drive roll shaft 1 fruit is travelled forward, or promoting fruit by the mode that pushes in addition moves forward on roll shaft.

During work, under the restriction of roll shaft 1 recess 11, oblate property fruit enters classification hole 2 with its flat position direction and roll shaft 1 parallel state according to diametric(al) all the time, thereby isolate the fruit of different-diameter size successively by different roll shaft spacing L1, classification is smooth and easy accurately, has greatly improved the grading effect of oblate fruit.
