The present invention relates to a sorting device for dried anchovies, which automatically sorts dried anchovies by several similar sizes.

In general, dried anchovies are selected and sold by seven kinds of sizes. In the past, many people are sorting by manual work, which is very inefficient, requires a long time, and requires a lot of manpower.

Therefore, the present applicant has invented a device for automatically sorting using wind power and filed it with patent application No. 87-11174. However, the automatic closing effect has eliminated the conventional closure, but it is very difficult to control the wind power and is completely unbalanced due to dry conditions. There were some drawbacks that could not expect a screening effect.

The present invention has been devised to solve such disadvantages to obtain a very good screening effect, which will be described in detail based on the accompanying drawings.

In the inside of the sorting base (1), a plurality of cylindrical sorting cylinders (2) and (2 '), which become narrower from right to left, are laid out on the rotating shaft (3) with the rear side inclined upward at a predetermined interval. (3) is connected to the chain (4) and the sprocket (5) to be rotated in the same direction at the same time, and under each sorting network (2), (2 ') to form an anchovy support plate (6) in the shape of its lower end The outlet 6 'is connected to the transfer duct 7 which is inclined on the left side of each sorting network 2, 2', and the top of the transfer duct 7 narrowing toward the left side is the next sorting network 2, respectively. , The lower end is connected to the air blowing duct 9 which becomes narrower gradually, while the lower end is communicating with the rotary shaft 3 at the front lower side of the sorting network 2 and 2 '. Receiving and rotating the rotating rotating shaft 10 and the inside of the suction pipe (12) that is discharged from the suction duct 11 is fixedly installed A half suction port 14 is formed toward the discharge guide 13 of the negative portion. An anchovy base plate 15 is installed at the lower part of the rotating mesh tube 10, and the outlet is connected to the blowing duct 9, and each sorting mesh tube 2 is formed. , 2 ') has a structure in which a detaching brush 16 is installed to flow up and down.

In the figure, reference numeral 17 is an input hopper, 18 is a conveying conveyor, 19 is a blower, 20 is an air control port of the suction duct 11, 21 is a control panel for adjusting the amount of air supplied to the air blowing duct 7, and 22 is a control panel. 21 is a handle to adjust.

Referring to the effects of the present invention as described above are as follows.

The sorting nets 2 and 2 'installed at regular intervals in the sorting main body 1 are arranged on the rotating shaft 3 and connected to the sprocket 5 and the chain 4, so that a motor (not shown) is operated to one side. Rotating the rotating shaft (3) of each of the sorting nets (2), (2 ') at the same time rotates in the same direction, and also the rotating meshes (10) located in the front lower portion of the sorting nets (2), (2') In response to the communication of the rotating shaft (3) is rotated at the same time.

Therefore, the large and small dry anchovies are transported through the conveying conveyor 18 while sucking and discharging air to the suction duct 11 and the blowing duct 9, so that the gap between the right and left sides of the sorting network 2, 2 'is increased. When the anchovies are put in the rear of the feeding tube 8, the sorting nets 2 and 2 'have the rear side upwardly inclined and are rotated by the rotary shaft 3, so the anchovies introduced into the rear side are slowly rotated. Anchovies that are smaller than the gaps of (2) and (2 ') are pulled out of the selection net (2) and (2') through the gaps, and the anchovy that is not larger than the gaps of the selection net (2) and (2 ') Since the position is transferred to the lower front by the inclination of the nets 2 and 2 ', it flows out of the sorting nets 2 and 2' so that the primary sorting is performed, and then the primary sorting is performed. 2), anchovy coming out of (2 ') is rotated in the same direction as the sorting network (2), (2') below Falling to the upper surface of the mesh tube 10 is discharged to the discharge guide 13 of the rear side where the secondary sorting is carried out when the primary anchovies fall on the upper surface of the rotating mesh 10, the inside of the rotating mesh 10 Since the suction port 14 of the suction pipe 12 installed is formed about half of the discharge guide 13, the anchovy of the size that can overcome the air suction input of the suction port 14 of the anchovy dropped in the upper portion of the rotary mesh 10 Irrespective of the suction force, it is dropped into the discharge guide 13 on the side and discharged after being sorted secondly out of the separator body 1.

However, the small anchovy of the size which cannot overcome the air suction input of the suction port 14 is absorbed by the air suction input to the outer surface of the rotary mesh 10 and rotated, and passes through the suction port 14 formed in about half so that the suction force is eliminated. It falls by this, and is conveyed to the following sorting nets 2 and 2 'by the lower anchovy support board 15. As shown in FIG.

The large and small dried anchovies introduced into the grind feeder 8 enter into the primary sorting nets 2 and 2 'and are first sorted by the sorting nets 2 and 2'. The screening effect is very excellent because it is discharged to the discharge guide after the second screening at the top of (10).

On the other hand, in the process of the primary sorting by the sorting nets (2), (2 '), the anchovy exiting into the gap between the sorting nets (2), (2') is connected to the transfer duct (7) Under the guide of the anchovy support plate (6) to enter the inside of the transfer duct (7), the transfer duct (7) is the input tube (8) of the sorting net (2), (2 ') of the upper and lower ends are smaller than the gap respectively; ), And the smaller anchovy drawn into the transfer duct (7) is raised by the wind introduced from the blowing duct (9), so that the next sorting network (2), (2 ') is connected to the blowing duct (9). ) Into the feeding tube (8) and the above-mentioned operation, the gap is smaller than before, the sorting anchovies by the sorting net (2), (2 ') is selected accordingly and again the sorting net (2), (2') The less anchovy missing through the gap of the is transferred to the next sorting network (2), (2 ') by the transfer duct (7) to sort the smaller anchovy, so When the film is transported far anchovy screening Menton (2), (2 ') anchovy is being completely screened by size.

On the other hand, the first sorting in the sorting nets (2), (2 ') is dropped into the rotary netting (10), the second stage of the process of the air suction input in the process of overcoming the rotation does not overcome the suction in the rotating mesh (10) state of suction force Anchovies dropped by self-weight due to resolving enter the blow duct 9 by the anchovy support plate 15 installed on the lower side thereof, and together with the anchovies that are not sorted first by the sorting pipes 2 and 2 '. It is transferred to small sorting nets 2 and 2 'and sorted continuously by size by the operation as described above.

In the present invention, assisting such a sorting operation is narrowed as the blow duct (9) toward the left side and the transfer duct (7) also become narrower as well as the wind is weaker wind pressure toward the down anchovy size It is possible to sort by size by smoothly transporting according to the condition. When there is a difference in the weight of the anchovy due to the excess moisture content according to the dry state of the anchovy, the control plate 21 is lowered by the handle 22 to adjust the inflow of wind. If the anchovy dry state can be effectively selected.

In the practice of the present invention, it should be noted that in the suction force control of the rotary mesh 10, which is the secondary sorting process, the mixture is partially mixed in the anchovies discharged through the primary sorting meshes 2 and 2 '. Care should be taken to control the intake air so that only small anchovies can be adsorbed.

And the upper part of each sorting net (2), (2 ') is installed so that the desorption brush (16) flows in the vertical direction to prevent the anchovy from being caught in the gap between the sorting net (2), (2'). In addition, debris such as anchovy scales are inserted into the gaps of the sorting nets 2 and 2 'to prevent the gaps from being narrowed.

As described above, the present invention has a screening effect because the anchovies are automatically selected in two steps by adsorption force of air using a plurality of sorting nets 2, 2 'and the rotating net 10, which become narrower as a gap. Not only can it work very well, efficiently and quickly, but it also has the effect of drastically reducing the number of workers, thus reducing labor costs.
