CN201404918Y - Double size grader - Google Patents

Abstract

The utility model discloses a double size grader, which belongs to technical field of fruit grading processing machinery. The double size grader comprises a rack and grading units which contain conveyors and roll bars and are installed at the rack. The double size grader is characterized in that: two or more grading units are provided, the grading units are installed at the rack and are layered, the space between the roll bars of the grading unit at the top layer is the largest, the space between the roll bars of the grading unit at the lower layer is smaller than the space between the roll bars of the grading unit at the upper layer in turn. The grading units are respectively around the rack in a concentric-square shape. The double size grader has reasonable and compact structure, the production cost is low, the use is convenient, and the management and the maintenance are convenient, meanwhile the utility model is durable. The fruits enter into the double size grader; the rack simultaneously contains a plurality of grading units whose space between the roll bars is progressively decreased, and the grading units sort out the fruits according to the grades from large to small. Themaintenance and the operation of the double size grader are convenient, and any environmental pollution does not exist. Meanwhile, the double size grader has simple assembling and debugging, small occupied site; the fruit grading processing expenses are decreased.

Description

Compound size classifier

Technical field

The utility model relates to the size classifier that the fruit commercialization adds man-hour, belongs to fruit grading processing equipment technical field.

Background technology

Existing fruit size classifier contains the stage unit that conveyer and roller thick stick form and constitutes by installing on the frame, and grader of a stage unit formation is installed on each frame.As need fruit is divided into a plurality of grades, during use, grader is arranged according to the grade shape that is in line from small to large.Because what adopt is that grade of per minute just needs a stage unit that is sleeved on the frame.Even structural design is compact again, it is long also to be difficult to solve production line, and equipment manufacturing cost is too high, the present situation that occupied ground is too big.

The utility model content

The purpose of this utility model is to add at fruit at existing size classifier to have above-mentioned deficiency man-hour, and a kind of compact conformation that has is provided, and low cost of manufacture is easy to use, helps the compound size classifier of managing, safeguarding.

The purpose of this utility model is to realize like this, compound size classifier, comprise frame and the rack-mounted stage unit that contains conveyer and roller thick stick formation, it is characterized in that described stage unit has two or more, the stage unit layering is installed on the frame, the roller thick stick gap maximum of top layer stage unit, the roller thick stick gap of lower floor's stage unit are successively less than the roller thick stick gap of upper strata stage unit.

Described each stage unit is back-shaped respectively to be looped around on the frame.

The utility model compactness rational in infrastructure, low cost of manufacture, easy to use, be convenient to management, safeguard, durable in use.Fruit enters compound size classifier, is comprising the stage unit that several roller thick stick spacings are successively decreased in the frame simultaneously, and fruit is sorted out according to from big to small rank.This device safeguards, and is easy to operate and do not have any environmental pollution.Simultaneously to have an assembling and setting simple for this device, and occupied ground is little, reduces the fruit grading processing charges.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1,2,3 stage units, 4,5,6 conveyers, 7,8,9 outlets.

The specific embodiment

Install on frame and contain the stage unit 1,2,3 that conveyer 4,5,6 and roller thick stick constitute respectively, each stage unit is back-shaped respectively to be looped around on the frame.The end face conveying roller thick stick of stage unit 1 is higher than the height of the end face conveying roller thick stick of stage unit 2, and the height of the end face conveying roller thick stick of stage unit 3 is lower than the height of the end face conveying roller thick stick of stage unit 2.Between the roller thick stick of roller thick stick gap greater than stage unit 2 of stage unit 1, between the roller thick stick of roller thick stick gap less than stage unit 2 of stage unit 3.Stage unit 1,2,3 is provided with outlet 7,8,9 respectively.

When being arrived stage unit 1 by the classification processed fruit, fruit greater than stage unit 1 roller thick stick gap comes out from the outlet 7 of afterbody, then from the gap, leave out by mistake the sorting of carrying out next grade to the stage unit 2 less than the fruit in stage unit 1 roller thick stick gap, and the like, the fruit of well-graded each grade is then from corresponding outlet output, and the outer fruit of minimum grade is then exported from conveyer 4.

Claims (2)

1, a kind of compound size classifier, comprise frame and the rack-mounted stage unit that contains conveyer and roller thick stick formation, it is characterized in that described stage unit has two or more, the stage unit layering is installed on the frame, the roller thick stick gap maximum of top layer stage unit, the roller thick stick gap of lower floor's stage unit are successively less than the roller thick stick of upper strata stage unit intermittently.

2, compound size classifier according to claim 1 is characterized in that described stage unit is back-shaped to be looped around on the frame.
