Description

A grading plant for blueberry

Technical Field

The utility model relates to a classified screening technical field, in particular to a grading plant for blueberry.

Background

Blueberry. The English designation Blueberry means blue berry belonging to the Ericaceae family, Vaccinium genus. Originating in north america, the perennial shrub berry tree. The fruit is blue, so it is called blueberry. The blueberry fruit contains rich nutrient components, has the functions of preventing cranial nerve aging, protecting eyesight, strengthening heart, resisting cancer, softening blood vessels, enhancing human body immunity and the like, and has high nutrient components. The blueberry is rich in anthocyanin, has the effect of activating retina, can strengthen eyesight and prevent eyestrain, and is attractive. Is also one of five healthy fruits recommended by the world food and agriculture organization.

The blueberry needs to grade the size of fruit at the in-process of actually picking the packing, and traditional blueberry grading process is accomplished by the manual work, and it not only consumes more manpower resources, and operating personnel intensity of labour is big moreover, and classification efficiency is low.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a grading plant for blueberry is favorable to improving blueberry classification efficiency.

In order to solve the technical problem, the utility model discloses a technical scheme does:

a grading device for blueberries comprises a rack, a hopper, a grading sieve plate, a collecting device and a discharge chute; a plurality of hoppers and a discharge chute are sequentially arranged on the upper end surface of the rack at intervals; the adjacent hoppers and the discharge chutes which are positioned at the tail ends are connected through a grading sieve plate which is arranged obliquely downwards, the height of the grading sieve plate is reduced step by step, and the front side and the rear side of the grading sieve plate are provided with protective plates; a collecting device is arranged under the grading sieve plate; a plurality of sieve separating holes are formed in the bottom end face of the classifying sieve plate, and the aperture of the sieve separating holes in the classifying sieve plate is gradually increased.

Furthermore, the hopper and the grading sieve plate are provided with three stages.

Furthermore, a slope is arranged in the inner cavity of the hopper positioned at the last two stages.

Further, the volume of the hopper is reduced in turn.

Furthermore, a material guiding hopper is arranged between the grading sieve plate and the collecting device.

The utility model has the advantages that:

the utility model utilizes the hopper to match with the grading sieve plate to grade the blueberry fruits, greatly reduces the labor intensity of traditional manual grading, improves the grading efficiency and simultaneously ensures the grading precision; when the blueberry screening machine is used, blueberry fruits are placed in a hopper at the beginning end, manual material stirring is carried out, the blueberry fruits fall down along a grading sieve plate step by step, and screening of the blueberry fruits with different fruit diameters is completed in the process that the blueberry fruits pass through the grading sieve plate; the blueberry fruits with smaller fruit diameters are selected firstly and fall into a collecting device below the corresponding grading sieve plate, and the blueberry fruits with larger fruit diameters continue to move forward for further screening; the hopper positioned at the later stage can delay the descending speed of the blueberry fruits and has the effect of temporary stay; the blueberry fruits after being classified and screened respectively enter different collecting devices and discharge chutes.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1-a rack, 2-a hopper, 3-a grading sieve plate, 4-a collecting device, 5-a discharge chute, 6-a protection plate, 7-a grading sieve hole, 8-a slope and 9-a guide hopper.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, a blueberry grading device comprises a frame 1, a hopper 2, a grading sieve plate 3, a collecting device 4 and a discharge chute 5; a plurality of hoppers 2 and a discharge chute 5 are sequentially arranged on the upper end surface of the rack 1 at intervals; the adjacent hoppers 2 and the discharge chutes 5 positioned at the tail ends are connected through the grading sieve plates 3 which are obliquely and downwardly arranged, the heights of the grading sieve plates 3 are gradually reduced, and the front side and the rear side of each grading sieve plate 3 are provided with the protection plates 6; specifically, the top end of the grading sieve plate 3 is connected with the discharge port end of the previous hopper 2, and the bottom end of the grading sieve plate 3 is connected with the feed port end of the next hopper; a collecting device 4 is arranged under the grading sieve plate 3; a plurality of sub-sieve holes 7 are formed in the bottom end face of the classifying sieve plate 3, and the aperture of the sub-sieve holes 7 in the classifying sieve plate 3 is gradually increased. The size of the sieving holes 7 can be set according to specific needs.

Specifically, in order to guarantee the effect of classified screening, hopper 2 and hierarchical sieve 3 all are provided with the tertiary to can obtain the blueberry of four kinds of different fruit footpaths, thereby satisfy different demands.

Specifically, a slope 8 is arranged in the inner cavity of the hopper 2 positioned at the last two stages. The setting on slope 8 can promote the flow of blueberry fruit to can reduce the whereabouts of artificial intervention blueberry fruit, at this moment, the operation personnel only need be responsible for in the top hopper the dialling of blueberry fruit can.

In particular, in order to increase the compactness of the device structure, the volume of the hopper 2 is reduced in sequence.
