Abstract

The utility model discloses a circulating sieve type automatic grader for granular fruits, such as oranges. The utility model is characterized in that the utility model comprises a machine frame on which two rollers are arranged in a rotating mode, wherein both sides of the rollers are respectively provided with a chain wheel and a chain, a plurality of sieve plates are tightly connected between the two chains, one shaft end of a roller shaft extends out of the machine frame to be used as a power input end and the front lower part and the lower part the sieve surface are respectively provided with an inclined bucket. Compared with a laminated type wooden sieve, the utility model has the advantages of productivity enhancement and labor intensity reduction; compared with a grader of a roller type sieve, the utility model has the advantages of simple structure, low cost, accurate grading and little damage.

Description

Automatic grader of granular fruit

The utility model belongs to a kind of and encircles the belt screen screening device, the particularly a kind of graininess fruit that follow motion, as the automatic grader of citrus.

Present existing graininess fruit, as the classification (screening) of citrus device, probably there are two kinds: the one, by the stacked wood sieve that manually shakes, this screening mode labour intensity is big, inefficiency, output are not high, so the large-scale classification production of uncomfortable cooperation; The 2nd, the grader that China Business mechanical investigations institute produces the eighties, version is the roll-type sieve of parallel elements, the roller work that rotates, the degree of accuracy of this classification mechanism complex structure, cost height and classification is relatively poor, damage ratio is higher.

The purpose of this utility model provides a kind of grader that is applicable to graininess fruit that adopts the belt screen form of shuttling movement, and it is simple in structure, cost is low, classification degree of accuracy height, damage ratio is low and output is big, can overcome the shortcoming of prior art.

The utility model is achieved in that a kind of automatic grader of graininess fruit, it is characterized in that having comprised frame.Two sizable cylinders respectively are rotatably assorted on frame by its axle, four sprocket wheels are separately fixed at the both sides of two cylinders, adorning same chain on the same side chain wheel of two cylinders, the strip sieve plate that has sieve aperture above some is close to and is arranged between two chains, and constitute the compass screen surface of a motion capable of circulation with two chains bindings, the axle of two cylinders has an axle head to stretch out outside the frame and as power intake, the front lower place of the square end portion that advances of compass screen surface have a tipping bucket in order to collection screen on fruit and its Guiding machine outside, another tipping bucket is arranged in order to fruit under the collection screen and outside its Guiding machine below compass screen surface.

The sprocket wheel chain structure of such scheme replaces being considered as equivalent structure of the present utility model as adopting belt wheel belt composition and similar structures; Axle head can adopt form such as sprocket wheel, belt pulley, gear or shaft coupling of device as clutch end; Frame or tipping bucket can be designed to realize the different shape of described function according to concrete needs.The automatic grader of such scheme may be used solely to the fruit of a grade of sorting, also can use the machine composition production line of many different screen sizes to take the fruit of a plurality of grades of continuous sorting.

The operation principle of such scheme is to rotate by two cylinders of power drive, sprocket wheel by the cylinder both sides drives two chain row culture shuttling movements, be close to that the sieve plate that is attached in the middle of the chain is formed compass screen surface and with chain row culture shuttling movement, when fruit falls into compass screen surface, fruit less than screen size drops under the sieve and by outside the tipping bucket Guiding machine, follow then that compass screen surface moves to that front end falls and by outside another tipping bucket Guiding machine greater than the fruit of screen size, thereby reach the purpose of automatic classification.The utility model is compared with stacked wood sieve, has and boosts productivity and the advantage that reduces labour intensity: compare with the product of China Business mechanical investigations institute, have simple in structure, cost is low, classification is accurate, damage few advantage.

Below in conjunction with accompanying drawing the utility model is done to describe more specifically.

Fig. 1 is the cross-sectional schematic (being the A-A cutaway view of Fig. 2) of a kind of scheme of the utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the B-B cutaway view of Fig. 1.

With reference to Fig. 1～Fig. 3, this automatic grader, comprised frame 1, two sizable cylinders 2 and 3 each be rotatably assorted on frame 1 by its axle 4 and 5, four

sprocket wheels

6,7,8,9 are separately fixed at the both sides of cylinder 2 and 3, sprocket wheel 6 on the cylinder 2 and the sprocket wheel on the cylinder 38 are with adorning chain 10, sprocket wheel 7 on the cylinder 2 and the sprocket wheel on the cylinder 39 are with adorning chain 11, the strip sieve plate 13 that has sieve aperture 12 grades above some is close to and is arranged between

chain

10 and 11, and link with

chain

10 and 11 and constitute the compass screen surface 14 of a motion capable of circulation, a shaft end of the axle 4 of cylinder 2 stretches out outside the frame 1 and sprocket wheel 15 is housed as power intake, at the side of advancing of compass screen surface 14 (C to) but there is on tipping bucket 17 collection screens fruit front lower place of end 16 and its Guiding machine outside, but fruit is arranged under tipping bucket 18 collection screens and outside its Guiding machine below compass screen surface 14.In addition, compass screen surface 14 tops also are provided with the fence 20 that row's (also can a row more than) is made of montant 19 grades, these montant 19 grades all are in the interstitial site between sieve aperture and the sieve aperture, can prevent that like this fruit is dull on the sieve aperture gap at motion process, with the accuracy rate of further raising classification; Also hanging the film bar 21 of some rubber etc. between these montant 19 grades, in order to reduce the movement velocity of fruit at compass screen surface, promptly increasing its screening machine meeting, effect also is the accuracy rate that further improves classification.

During use, place water receiving fruit container (form the occasion of production lines at many graders, tipping bucket 18 also can lead the compass screen surface of another grader) respectively in the front lower place of tipping

bucket

17,18, power is after sprocket wheel 15 inputs.Cylinder 2 and 3 rotates, compass screen surface 14 along C to making shuttling movement, at this moment fruit can fall into compass screen surface 14 continuously, size drops to tipping bucket 18 and is directed to water receiving fruit container from sieve aperture 12 grades less than the fruit of sieve aperture, size then moves to end 16 with compass screen surface 14 greater than the fruit of sieve aperture and drops to tipping bucket 17, and be directed to another water receiving fruit container, thereby these two water receiving fruit containers just obtain the fruit of two different stages.
