Description

  The present invention relates to an improvement of an automatic sorting device for cultured shellfish such as scallops and oysters.

  Conventionally, in order to ship cultured shellfish such as scallops and oysters that have been cultivated, it is ideal that the sorting work for separating shells into large, medium and small is done manually to prevent damage to the cultured shellfish. However, in order to improve work efficiency and reduce labor, sorting by machines is the mainstream.

There are a wide variety of cultured shell sorting devices that have been used in the past, but in order to sort shells efficiently, a sieve plate with a large number of holes where medium-sized or smaller cultured shells fall and a small cultured shell fall. A hopper for forming a sorter having upper and lower sieve plates each having a large number of holes to be opened and positioned with the inlet side of the sorter being inclined high and the outlet side being inclined low, and containing the cultured shellfish above the sorter Is formed.

The sorting table is pivotally supported by eccentrically supporting one end of a support arm on a pulley transmitted from a driving source, and the other end is pivotally supported on the sorting table, and the sorting table is moved by eccentric movement by rotation of the pulley. 2. Description of the Related Art A sorting device is known in which a cultured shell on a sieve plate is moved by swinging and dropped from a hole of a predetermined size for sorting.

JP-A-8-256629 Actual Kaihei 8-10412

All of the above-described sorting apparatuses are positioned with the inlet side of the sorting table being high and the outlet side being lowered so that the whole is inclined, and swinging means from the drive source is provided on the inlet side, and the lower side is the base of the sorting apparatus. It is formed in support. Therefore, the vibration of the sorting table vibrates strongly on the upper side and vibrates small on the lower side because it is only supported by the base. On the other hand, the cultured shells to be selected vary in size, shape, and the presence of deposits on the surface, so the frictional resistance of the cultured shells is different.

Therefore, since the moving speeds of the cultured shells moving on the sorting table are not uniform and are not constant, the cultured shells are likely to overlap each other and are difficult to fall from the predetermined hole, and it is difficult to effectively select the shells. Moreover, since the inclination angle of the sieve plate attached to the sorting table is large, the moving cultured shell H is likely to be caught in the hole in the middle of dropping as shown in FIG. The cultured shells fitted in the holes are more strongly fitted by the vibration of the sorting table and are not easily removed.

If the cultured shells fit into the holes one after the other, the movement of the other cultured shells will be disturbed, and the flow of the cultured shells will deteriorate, and if many sorting holes are blocked, the small shells will pass through without being sorted and the sorting efficiency will be improved. Cause it to fall. In addition, cultured shells fitted in holes are difficult to remove because they are strongly fitted by vibrations, and if removed forcibly, the cultured shells are chipped or cracked, resulting in poor yield of shipped shellfish. ing.

  The problem to be solved by the present invention is to reduce the speed of the moving shell by making the tilt angle of the sorting table for sorting the cultured shells horizontal or gentle, thereby causing damage due to the collision of the cultured shells.

The sorting table is supported.

By springing and supporting the four corners of the sorting table 20 with springs 18, the burden of the vertical movement on the swing arm 17 can be reduced even when a large amount of cultured shell H is placed on the sorting table 20 and becomes heavy. Since the eccentric motion can be smoothly performed, the sorting operation can be performed efficiently.

FIG. 11 shows a second embodiment of the driving device S, which is formed by attaching one driving device S to each of the one-side working wheels 13a, 13b of the pair of rotating shafts 12 supported by the bearing portion 11 of the base frame 2. It is. By driving the drive wheel 9a and the working wheel 13a close to each other and shortening the interval between the transmission means T, the drive source is attached to each rotation shaft rather than driving the two rotation shafts with a single motor as a drive source. As a result, the burden on the motor can be reduced, and the motor can be reduced in size and weight, which is economical.

  Hereinafter, the operation of the sorting apparatus 1 according to the present invention will be described. In the sorting operation process, the cultured shellfish H for shipping collected from the sea is accommodated in the hopper 31. Next, the driving wheel 5 of the driving device S is operated to rotate the driving wheel 13 from the driving wheel 9 supported on the driving shaft 7 via the transmission means T, so that the operating wheel 13 and the sorting table 20 are interposed. The sorting table 20 is swung by the swing mechanism U provided.

As shown in FIG. 12A, when the operating wheel 13 rotates and the eccentric shaft 14 comes to the uppermost position W, the shell H on the sieve plate 25 is moved by an arrow. As shown in FIG. 5, the vehicle advances while being pushed up from the position of the last retracted position Y to the position of the uppermost position W.

Next, as shown in FIG. 12B, when the eccentric shaft 14 rotates and moves to a position on the same horizontal plane parallel to the axis of the operating shaft 13, both the sieve plate 25 and the shell H descend while moving forward in the horizontal direction. Move to the most advanced position X.

Further, as shown in FIG. 12C, when the eccentric shaft 14 rotates and descends to the lowest position, the sieve plate 25 moves back to the lowest position Z at the same position as the uppermost position W of FIG. Since the sieve plate descends rapidly when the sieve plate 25 is lowered, the shell H on the sieve plate temporarily floats in the air and remains at the most advanced position X as it is.

Furthermore, as shown in FIG. 12D, the eccentric shaft 14 is further rotated and moved back to the most retracted position Y located on the same horizontal plane parallel to the axis of the operating shaft 13, and stayed at the most advanced position X. The shellfish H rises together with the sieve plate at the most advanced position X at the position where the sieve plate is retracted, and moves forward to the uppermost position W (FIG. 12A).

As described above, from the reciprocating motion in which the sorting table 20 is moved in parallel from the last retracted position Y to the most advanced position X by the swing mechanism U with one rotation of the operating shaft 13, and the vertical motion rod from the highest position W to the lowest position Z. By repeating this swinging motion, the cultured shellfish moves from the last retracted position Y to the most advanced position X through the uppermost position W, and only the sieve plate moves again to the last retracted position Y, so that the shellfish H It moves forward while performing a stepping motion, and the size of the shellfish is appropriately selected by the holes 26 and 28 of the first and second sieve plates 25 and 27 so as to be dropped and discharged.

The moving large shell reaches the outlet side without falling from the hole 26 of the first sieve plate 25 and falls from the first guide shooter 30a, and the medium-sized and small cultured shells H move on the first sieve plate 25, respectively. While moving, it is sifted off at the hole 26 and dropped onto the second sieve plate 27, and the medium-sized cultured shellfish is moved on the second sieve plate 27 to the outlet as it is and is accommodated in the accommodation container 40 from the second guide shooter 30b. The Further, the small cultured shell H is further screened through the hole 28 of the second sieve plate 27 and is stored in the storage container 40 from the third guide shooter 30c for the small shell.

Accordingly, the shell is smoothly moved by swinging the sorting table 20 attached to the swinging mechanism U while the sorting table 20 is slightly inclined to the horizontal or outlet side, and the first and second sieve plates 25 and 27 are moved. Since the cultured shell H that moves above moves in a horizontal state without jumping or dancing due to swinging, it can be moved without being fitted into the hole of the sieve plate.

Even if the shell fits into the hole, the shell can be detached from the hole by the movement of the eccentric motion, the movement of moving backward from the bottom to the horizontal direction in FIG. Since it can reduce the phenomenon of being stuck, it can prevent the shells from clogging in the sorting holes and pass through the small shells without sorting, and the cultured shells moving on the sieve plate overlap. It can move smoothly without clogging and perform sorting work efficiently.

Further, since the sorting table 20 reciprocates and moves up and down in the horizontal direction, when the cultured shell H moves while swinging on the sorting table 20, the shell does not jump or dance, and is moved in a horizontal state. It is possible to prevent the shellfish from colliding with each other and cracking or cracking.

As shown in FIGS. 8, 9, and 10, a large number of cultured shells H can be obtained by pulling the four corners of the sorting table 20 with springs 18 from above, or by attaching the springs 18 to the four corners of the lower surface of the sorting table 20 and resiliently supporting them. Even when the sorting table 20 becomes heavier due to being placed on the hopper 31, by reducing the vertical movement of the sorting table 20 by the elastic force of the spring 18, the load on the swing arm 17 is reduced and the eccentric motion is reduced. Therefore, the sorting operation can be performed efficiently.

As shown in FIG. 11, by attaching the driving device S for swinging the sorting table 20 to the working wheel 13 and operating the swing mechanism U, the load on the motor can be reduced, so the motor is reduced in size and weight. It is economical because it can be done.
