Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sieve incorporated in a shiitake mushroom sorter.

Currently, the selection of shiitake mushrooms is based on almost uniform nationwide standards.

Generally speaking, Shiitake mushrooms are sorted on a belt conveyor and separated into large leaves, medium leaves, and small leaves by many hands, or they are sifted manually using a hexagonal hole basket or a vinyl basket with round holes. .

It is divided. By the way, the former method, in which dried shiitake mushrooms are sorted by a large number of people using a belt conveyor, often results in products that do not meet the standards and must be re-sorted, resulting in a failure rate, while the latter method, in which dried shiitake mushrooms are sifted using a basket, is extremely brittle. Moreover, since the amplitude of the sieving is large, the mushrooms are crushed and cracked and chipped, which not only deteriorates the quality but also requires heavy labor.

There are proposals to improve efficiency by mechanically sifting shiitake mushrooms, but the long legs of shiitake mushrooms get caught in the standard holes and stop the flow, so this cannot necessarily be said to be highly efficient.

This invention solves the drawbacks of the conventional sorting methods described above, and its purpose is to provide an automatic sorting method in which mushrooms are passed through mechanically. be.

The structure of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view of an example of a shiitake mushroom sorting machine, and FIG. 2 is a plan view of the same. The delivery belt conveyors A-1, A-2, and A-3 are the sieves of the present invention having four stages of sieving: large, medium, small, and shaking. Sieve A
-1, A-2, and A-3 are fixed to a frame body 5 supported by a frame 3 via a spring 4, and are subjected to vibration by a vibrader 6.

A receiving chute 7 is connected to these sieves, and the lowest sieve A-
3. A swinging chute Ta is provided below, and the upper receiving chute 7 is connected to a belt conveyor 9 via a parts feeder 8.
I have made it to you.

The tip of the trough 10 from the parts feeder is brought to one side in the width direction of the belt conveyor 9, and non-standard mushrooms on the belt conveyor 9 are taken out to the other side in the width direction of the belt conveyor by visual selection. Each of them passes through a receiving chute 11 and is thrown into a receiver 12 .

Alternatively, the lift-type shiitake supply stand 1 may be eliminated, and the delivery belt conveyor 2 may be a long one, and the mushrooms may be directly fed to this conveyor from the floor.

The sieves A-1, A-2, and A-3 have rectangular plates 13a and 13b, as shown enlarged in FIG. 3 and further enlarged in FIGS. 4 and 5.
, 13c are formed by punching out sieve holes 14a, 14b, 14c of a predetermined size at appropriate intervals on the entire surface of the plate, and notches 15 which successively become narrower widths following these holes, facing the lower side of the slope of the plate. At the same time, the punched plate piece 16 is continuous with the plate body only at the tip which gradually becomes narrower, and the punched plate piece is slightly inclined downward, and the inclined lower side a is further curved downward. . The illustrated punched plate piece has the hole side half cut out. The width of the circumferential notch 15 does not necessarily need to be made gradually smaller, but may have the same width over the entire length. Further, the plate piece 16 may be attached as a separate piece instead of being punched. Although the sieve holes 14a, 14b, and 14c are circular in the figure, they can also be polygonal.

This sieve has a structure as described above, and this sieve has a notch facing downward in the slope of the sieve following the sieve hole formed in the plate body, and this notch is deep on the sieve hole side and There is a bottom plate (punched board piece) that becomes shallower as it gets closer to the bottom, so if a mushroom that does not fall out even if it partially enters the sieving hole, even if the mushroom's foot has entered the hole, this foot will be attached to the bottom plate ( Since the mushrooms are successively pushed up by the punched plate pieces and extruded from the notches, there is no risk of the mushroom legs getting caught in the sieve holes and stopping the flow as in the conventional case.

The legs of shiitake mushrooms are not necessarily straight, but some are curved laterally, and some have relatively long legs, and these legs are connected to the lower side edge of the notch 15 at the notch in the sieve pit. When entering the gap 17 between both side edges of the punched plate piece 16, this gap becomes smaller as you reach the lower side of the slant of the sieve, so there is a risk that mushroom legs may get caught.
7 is closed with the side wall plate piece 18, thereby preventing the legs from getting caught and making it possible to make the flow of the shiitake mushrooms on the sieve smoother and more reliable.
