Description

The present invention relates to a shellfish discharging device for discharging shellfish from a Zabuton basket.

In the cultivation of scallops, scallop cages are generally used in the cultivation process. Zabton basket 1o is a container for growing shellfish by putting about 20 to 80 scallop shells in scallop farming and suspending them in the sea. The substantially quadrangular-pyramidal cage is composed of a bottom net 2 formed by stretching a net on a substantially square frame and side nets 3 consisting of substantially triangular four-sided nets continuous to each side of the bottom net 2. is. The Zabton basket 1o is mainly one with a side of the bottom net 2 of about 40 cm, but a larger size is sometimes used. Typically, 10 to 20 zabuton baskets 1o are vertically connected by connecting each top part and the center part of the bottom net 2 with a rope 4 at intervals of about 30 cm. Used as set 6. For example, the work of exchanging and cleaning the cage, and the work of discharging the shellfish from the Zabton cage 1o for the sale of the shellfish are frequently performed. The Zabton basket 1o is provided with a shellfish inlet/outlet 5o on the ridge line 3a connecting the vertex and one corner 2a of the bottom net 2, and shellfish are discharged through this shellfish inlet/outlet 5o.

At present, the operation of discharging shellfish from the Zabuton basket 1o is often performed manually. When the shells are to be discharged, an operator holds the clamshell basket 1o with the shells entrance 5o facing downward and rocks it left and right. When the zabton basket 1o containing the shellfish is held with the top portion facing directly downward, the shellfish inside accumulate near the top portion and the weight of the shellfish pulls the ridge line 3a to close the shellfish entrance 5o, so that the shellfish can be discharged efficiently. I can't let you. Therefore, the Zabton basket 1o must be tilted and held so that the shellfish entrance 5 faces directly downward, and is then swung left and right. The Zabuton basket 1o containing shellfish weighs about 2.5 kg to 3 kg, and it is extremely hard work to lift it with both hands and swing 10 to 20 baskets in an inclined state.

As a device for discharging shellfish from a Zabuton basket 1o, for example, a technique described in Patent Document 1 has been proposed. In this technique, a plurality of Zabuton baskets 1o are placed on a conveying body having a pair of left and right endless tracks and conveyed with the bottom net 2 facing upward, and the Zabuton baskets 1o being conveyed are conveyed from below to the side nets 3. The shell is ejected from the shell entrance 5o by hitting or vibrating the shell. The Zabuton basket 1o being transported moves while being pressed from above onto the endless track by the pressing part.

Recently, in some areas, the number of fishermen using new Zabton baskets in which the position of the shell entrance and exit has been changed is increasing. As shown in FIG. 1(a), the conventional Zabuton basket 1o has the shellfish entrance 5o at approximately the middle position of the ridgeline 3a (that is, the lengths of the upper and lower ridgelines 3a of the shellfish entrance 5o are approximately equal). ), in this new Zabuton basket 1, as shown in FIG. That is, there is no ridge line 3a on the lower side of the shell entrance 5, or the length of the ridge line 3a on the lower side is significantly shorter than the ridge line 3a on the upper side). By providing the shellfish entrance 5 at such a position, even a worker unfamiliar with the shellfish discharging work can easily remove the shellfish by vibrating the Zabton basket 1 with the corner 2a close to the shellfish entrance 5 facing downward. can be discharged.

It is difficult to properly discharge the shellfish inside the new Zabton basket 1 using the shellfish discharge device of the prior art. That is, as shown in Fig. 1(a), a conventional Zabton basket 1o in which a shellfish entrance 5o is provided approximately in the middle of the ridge line 3a has been developed for discharging shellfish, as proposed in Patent Document 1, for example. The prior art is a technique of treating the Zabton basket 1o in a horizontal or slightly inclined state. Therefore, when a new Zabuton basket 1 is processed using a conventional technique, the ridgeline 3a on the top side of the shell entrance 5 is longer than the conventional Zabuton basket 1o, so that the shells are placed near the top of the Zabuton basket 1 with the top facing downward. is accumulated and is not discharged from the shellfish entrance/exit 5.

Further, in the technique proposed in Patent Document 1, the Zabuton basket 1 is subjected to an impact from below. When an impact is applied from below, the shells and the Zabuton basket 1 vibrate up and down at the same time, so that the shellfish dances inside the Zabuton basket 1 and is difficult to be discharged. In order to deal with this problem, if you try to eject the shellfish by giving a strong and high-speed blow, problems such as vibration, noise, and quick consumption of the cage will occur. Shell cracking and biting may occur. The Zabuton basket 1 may come off from the carrier due to the impact.

Furthermore, adjacent Zabuton baskets 1 are connected by a rope having a length of about 30 cm. Since the rope is short, when a plurality of zabton baskets 1 are arranged flat on the conveying body so that their shell entrances 5 do not overlap, the zabton baskets 1 at the front in the traveling direction pull the zabton baskets 1 at the rear, blocking the shellfish entrances 5. It will come loose. As a result, shellfish may not come out of the Zabton basket 1 even when vibration or impact is applied, and eventually the shellfish must be discharged manually.

Therefore, the present invention provides a compact, lightweight, inexpensive and safe shellfish discharging device that can reliably discharge shellfish from a plurality of Zabton cages in a short time without adversely affecting the shellfish in the Zabton cages. , and a Zabton basket housing unit used in the shellfish discharging device.

The shellfish discharging device 30 includes a zabton basket storage unit 10 according to the present invention, a motor 33, and a vibrating mechanism that vibrates the zabton basket storage unit 10 so that each of the two inclined bottom surfaces 11 alternately moves up and down by the power of the motor 33. 34.

The Zabton cage storage unit 10 used in the shellfish discharging device 30 has support shafts 18 on each of the side walls 13 provided at both ends in the length direction. The Zabton basket storage unit 10 is vibrated by the action of the vibrating mechanism 34 with the straight line connecting the two support shafts 18 as the rotation axis, so that each of the two inclined bottom surfaces 11 alternately moves up and down, and as a result, the Zabton basket storage unit The Zabuton basket 1 accommodated in 10 vibrates as indicated by arrow A in FIG. 3(c). The position of the support shaft 18 is not particularly limited as long as the zabton basket storage unit 10 can be rotated around the support shaft 18, but the side wall 13 corresponds to the shellfish outlet 12 of the zabton basket storage unit 10. More preferably, it is provided at or near the location. By arranging the support shaft 18 at this position, the Zabton basket 1 can be vibrated so that the shellfish can be brought closer to the vicinity of the shell entrance 5 inside the Zabton basket 1 more effectively. In addition, by arranging the support shaft 18 at this position, the lateral swing of the cushion basket 1 (vibration in the direction of arrow A in FIG. 3(c)) is well balanced, and the vibration of the cushion basket storage unit 10 is small. The load on the motor 33 is also minimized.

The shellfish discharge device 30 includes a frame 31 that supports the zabton cage housing unit 10 . The frame 31 has a support portion 32 that rotatably supports the support shaft 18 of the Zabuton basket accommodating unit 10 at a position corresponding to the outside of the side wall 13 of the Zabuton basket accommodating unit 10 . A motor 33 is further attached to the frame 31 .

The motor 33 and the Zabuton basket housing unit 10 are connected by a vibrating mechanism 34 . The vibration mechanism 34 includes a rotating disk 341 attached to the output shaft of the motor 33, a connecting shaft 342 having one end rotatably attached at a position away from the center of the rotating disk 341, and the other end of the connecting shaft 342. and the other end of which is attached to the support shaft 18 of the Zabton cage housing unit 10.

The other end of the vibration shaft 343 is not limited to being attached to the support shaft 18, and may be attached to the side wall 13, the inclined bottom surface 11, or the side wall 14, for example.

It is preferable to arrange a shellfish conveying section 35 below the shellfish discharge port 12 of the Zabuton basket storage unit 10 . The shellfish conveying portion 35 is preferably an inclined plate so that the shellfish falling downward from the shellfish outlet 12 can be received and moved in one direction. Further, the shellfish discharging device 30 preferably has a water supply port 36 for supplying the shellfish transporting part 35 with water for flowing and moving the shellfishes that have fallen to the shellfish transporting part 35 .

[Shellfish discharging device according to the second embodiment]
4 schematically shows the structure of a shellfish discharge device 60 according to a second embodiment, FIG. 4(a) being a top view and FIG. 4(b) being a front view. Moreover, FIG. 5 is the figure which looked at the Zabton cage accommodation unit 10 and the vibration mechanism 63 of the shellfish discharge apparatus 60 from the left side. As the vibrating mechanism 63, for example, a mechanism having the same configuration as the swinging device according to Japanese Patent No. 5956666 owned by the applicant of the present application can be used.

The shellfish discharging device 60 includes a zabton basket storage unit 10, a vibrating body 61 that fixes and vibrates the zabton basket storage unit 10, a motor 62, and a vibration mechanism 34 that vibrates the vibrating body 61 by the power of the motor 62. Prepare. Although the springs 635c and 635d are shown on the left side of the chains 634a and 634b in FIG. 4(b), the springs 635c and 635d are shown in FIG. are shown to overlap behind the chains 634a, 634b. In addition, in FIG. 5, the spring 635a on the front side and the spring 645b on the back side are shown overlapping.

The vibrating body 61 has a pair of pipes 611 (611a, 611b) and connecting members 612 (612a, 612b, 612c) arranged parallel to each other, and connects both end portions and central portions of the pair of pipes 611a, 611b. They are connected by a member 612 to be integrated. A pair of pipes 611 is a member for vibrating the Zabuton cage housing unit 10 fixed thereon. The length may be long enough to fix at least one Zabuton basket storage unit 10, but it should be long enough to fix a plurality of Zabuton basket storage units 10 side by side. It is more preferable to have The width preferably corresponds to the width of the zabton basket storage unit 10. More specifically, the width is wider than the width of the clam outlet 12 of the zabton basket storage unit 10 and shorter than the distance between both side walls 14. width is preferred. Although the pair of pipes 611 is not particularly limited, they are preferably resin pipes such as vinyl chloride pipes from the viewpoint of weight reduction and durability. The pair of pipes 611 is not limited to pipes with a circular cross section, and may be rod-shaped bodies with a polygonal cross section.

Springs 635 (635a, 635b, 635c, 635d) are attached to the lower portion of the vibrating body 61 . Specifically, the springs 635a and 635b are attached to the lower portions of the connecting members 612a and 612b, respectively, and the springs 635c and 635d are attached to the lower portions of the longitudinal centers of the pipes 611a and 611b, respectively, that is, the third and fifth springs to be described later. is installed near the joint of the Thereby, the vibrating body 61 is supported so that each of the pipes 611a and 611b can vibrate in the vertical direction. Each lower end of the spring 635 is attached to a fixed object such as a frame having a certain height as illustrated by the dashed line in FIG. It can be placed at any height.

The motor 62 generates a rotational force that serves as power for vibrating the vibrating body 61 . A rotational force generated by the motor 62 is transmitted to the vibration mechanism 63 connected to the motor 62 . As shown in detail in FIG. 5, the vibrating mechanism 63 includes a crank mechanism including a disk-shaped rotating disc 631 and a connecting shaft 632, a vibrating shaft 633, and chains 634a and 634b. The rotational force of the motor 62 rotates the rotating disk 631 attached to the output shaft of the motor 62, thereby causing the connecting shaft 632 connected to the rotating disk 631 to reciprocate. One end of the connecting shaft 632 is rotatably connected to the vibrating shaft 633 . The reciprocating motion of the connecting shaft 632 is transmitted to the oscillating shaft 633, thereby causing the oscillating shaft 633 to oscillate about the axis 633p.

A chain 634a is connected to the oscillating shaft 633 between the connecting portion with the connecting shaft 632 and the shaft 633p, and a chain 634b is connected to the position on the opposite side across the shaft 633p. there is Therefore, the chains 634a and 634b are alternately pulled by the vibrating shaft 633 swinging around the shaft 633p.

Here, the operation and state of the connecting shaft 632, the oscillating shaft 633, and the chain 634 when the oscillating shaft 633 swings will be described. In FIG. 5, the vibrating shaft 633 swings about the axis 633p. First, consider the state where the right side of the vibrating shaft 633 is raised (that is, the left side is lowered). At this time, the chain 634a is relaxed. As the right side of the oscillating shaft 633 is lowered, the chain 634a is stretched and at some point fully tensioned. At this moment, the entire chain 634a is abruptly pulled by the vibration shaft 633, so that the pulling force is transmitted to the upper end of the chain 634a along with the impact. The chain 634a is pulled by the oscillating shaft 633 while the right side of the oscillating shaft 633 continues to move downward. Eventually, the chain 634a relaxes as the motion is reversed so that the right side of the oscillating shaft 633 goes up (ie the left side goes down). Then, similarly, as the left side of the oscillating shaft 633 descends, the loose chain 634b is stretched and taut, and the pulling force is transmitted to the upper end of the chain 634b with an impact. In time, chain 634b relaxes as oscillating shaft 633 reverses its direction of motion again. Since the above operation is repeated, the tensile force from the vibration shaft 633 is alternately and repeatedly transmitted to the chain 634a and the chain 634b along with the impact.

Note that the chain 634a and the chain 634b are not limited to this, and similar effects can be obtained as long as they are configured to transmit tensile force without transmitting pressing force. You may make it comprise a rope or a wire.

The upper end of the chain 634a is connected to the pipe 611a forming the vibrating body 61. As shown in FIG. Therefore, the tensile force transmitted to the chain 634a is transmitted to the pipe 611a, causing the vibrating body 61 to vibrate. Also, the upper end of the chain 634b is connected to the pipe 611b that constitutes the vibrating body 61 . Therefore, the tensile force transmitted to the chain 634b is transmitted to the pipe 611b, causing the vibrating body 61 to vibrate. As described above, since tensile force accompanied by impact is alternately transmitted to the chains 634a and 634b, the vibrating body 61 supported by the spring 635 alternately impacts the pipes 611a and 611b. It vibrates intricately under the applied tensile force.

At this time, each of the pipes 611a and 611b receives a downward tensile force from the chains 634a and 634b. are respectively arranged to support the pipes 611a and 611b against the downward tensile force, effectively preventing the central portions of the pipes 611a and 611b from bending downward. Therefore, compared to the case where the springs 635c and 635d are not used, the pipe 611 does not need to be made strong, so the weight of the vibrating body 61 can be reduced. It can be relatively small to match the lightweight vibrating body 61 .

The Zabuton cage housing unit 10 is fixed on the vibrating body 61 . The Zabuton basket housing unit 10 can be fixed to the pipes 611 a and 611 b of the vibrating body 61 via the unit fixing member 65 . In FIGS. 4 and 5, two unit fixing members 65 are attached to each of the two side walls 13 of the Zabuton basket housing unit 10 . On each side wall 13 , two unit fixing members 65 are arranged on either side of the shellfish outlet 12 .

The unit fixing member 65 can have the configuration shown in FIG. 5, for example, and has a substantially rectangular rubber plate 651 . The rubber plate 651 has a through-hole 652 in a substantially central portion, through which the pipes 611a and 611b of the vibrating body 61 can pass. In FIG. 5, the pipes 611a and 611b are depicted as having a smaller diameter than the through hole 652, but this is for the purpose of showing the structure in an easy-to-understand manner. and 611b, the outer diameter of the pipes 611a and 611b and the inner diameter of the through-hole 652 are preferably approximately equal.

It is preferable that the Zabuton cage housing unit 10 can be easily attached to and detached from the vibrating body 61. Therefore, the through hole 652 is provided as an inverted U-shaped opening continuing from the lower side of the rubber plate 651, and the pipes 611a and 611b are connected to the rubber plate 651. It is preferable that it can be accommodated in the through hole 652 from the opening portion of the lower side of the . When the Zabuton cage housing unit 10 is fixed to the vibrating body 61, the Zabuton cage housing unit 10 is placed from above the vibrating body 61 so that the pipes 611a and 611b are accommodated in the through holes 652, and then the pipes 611a and 611b are inserted. An opening closing plate 653 for closing the U-shaped opening is fixed to the rubber plate 651 so as to surround it. In this manner, the two pipes 611a and 611b are arranged in parallel with the length direction of the Zabuton basket accommodating unit 10 outside the inclined bottom surface 11 of the Zabuton basket accommodating unit 10. As shown in FIG.

The number of unit fixing members arranged on each of the two side walls 13 is not limited to two. The unit fixing member may be, for example, one plate-like body provided with two through-holes for passing the pipes 611a and 611b, respectively. Alternatively, each of the pipes 611a and 611b can be more firmly held in the through hole by using, for example, two unit fixing members corresponding to each of the pipes 611a and 611b on each of the two side walls 13. may Alternatively, one unit fixing member having through holes for passing the pipes 611a and 611b is provided, for example, at the bottom of the Zabuton basket accommodating unit 10, and the Zabuton basket accommodating unit 10 is fixed to the vibrating body 61 via this unit fixing member. good too.

By fixing the Zabuton basket housing unit 10 to the vibrating body 61 , the vibration of the vibrating body 61 is transmitted to the Zabuton basket housing unit 10 . Therefore, the Zabuton basket storage unit 10 vibrates intricately in the direction indicated by the arrow A in FIG. The details of the complex vibration of the Zabuton basket housing unit 10 are as follows. That is, the pipes 611a and 611b are alternately moved up and down, so that the Zabton basket housing unit 10 swings so that each of the two inclined bottom surfaces 11 alternately moves up and down. Since the pipes 611a and 611b are connected by the connecting member 612 and supported by the spring 635, the movement is not a monotonous repetitive movement of a fixed period but an irregular movement in which the center of gravity always moves. . That is, the vibrating body 61 and the Zabuton basket accommodating unit 10 fixed thereto vibrate with rocking movement. Furthermore, as described above, the vibrating mechanism 63 that transmits the power to the vibrating body 61 is not a rod-like member with a fixed length, but a flexible member such as a chain, a rope, or a wire. Rather than a simple push-pull motion, the difference in motion induces a striking force and generates a large impact vibration. As a result, the shellfish in the Zabton basket storage unit 10 are shaken in all directions and quickly discharged from the shellfish entrance 5.例文帳に追加In this embodiment, since the pipes 611a and 611b are connected by the connecting member 612, the vibrating body 61 vibrates with rocking motion. If the plurality of parts of the vibration body are not connected or loosely connected with an elastic member, the plurality of parts of the vibrating body will vibrate separately, and the object of the present invention can be achieved even in this way. can.

In the embodiment shown in FIG. 4, one Zabuton basket housing unit 10 is fixed to the vibrating body 61, but in another embodiment, on the vibrating body 61, in the horizontal direction of FIG. A plurality of Zabton basket storage units 10 can also be fixed so as to be juxtaposed. Also, while in the embodiment shown in FIG. 4 the lower ends of the springs 635 of the vibrating mechanism 63 are attached to the frame, in another embodiment, instead of the frame, a conveyor system may be used to allow each of the springs 635 to If the lower end of the shell is attached to the edge of the conveyor device so that the conveyor surface (shellfish conveying part) that moves below the shellfish discharge port 12 of the Zabton basket storage unit 10 is positioned, the shellfish will be discharged from the Zabton basket 1 and dropped downward. The shellfish can be automatically transported to a predetermined position by a conveyor.
