TECHNICAL FIELD The present invention relates to a compressing device for compressing a resin net culture material used for culturing cultured shellfish to reduce its volume.

Young scallops can be collected by attaching larvae of scallops to a seedling collector. As shown in FIG. 1(a), the seedling collector N can be made by combining two types of resin nets with different mesh sizes (generally called "Netron nets"). An inner bag longer than the outer bag and having a larger mesh is pushed into the outer bag, and both ends of the outer bag are closed to form an overall swollen shape. As shown in FIG. 1(b), 15 to 20 pairs of seedling collectors N (generally called "paper lanterns") manufactured in this way are connected with two of them as one group. 30 to 40 seedling collectors are thrown into the sea as one series (a plurality of seedling collectors Ns). The number of seedling collectors Ns to be thrown into the sea varies depending on the region and production volume. The seedling collector Ns thrown into the sea is unloaded after several months, and the young scallops separated from the seedling collector Ns are replaced in a Zabton basket or the like. The seedling collector Ns from which the young scallops have been removed is washed and stored until the next time it is thrown into the sea.

The netron net, which is the material of the seedling collector N, is very light, and the weight of the series of seedling collectors Ns is about 2 kg at most. not large enough. Therefore, 30 to 40 seedling collectors Ns are arranged in one row, and aquaculture materials consisting of 300 to 500 rows in total occupy a large space when stored as they are, so securing a storage space is a problem. Become. In addition, aquaculture materials with a large volume are difficult to handle when being transported by truck from a storage location to a fishing boat or when being loaded onto a fishing boat. Furthermore, large-capacity aquaculture materials are limited in the amount that can be loaded on a fishing boat, and work such as tying them to prevent them from falling into the sea during navigation is necessary, which is complicated.

Traditionally, fishermen have reduced the volume of aquaculture materials by pushing them into hand-made wooden boxes, pressing them down, compressing them, and tying them with ropes. By doing so, we have dealt with the problem of the volume of aquaculture materials. As for the former wooden box, there are cases where a wooden box that can hold 2 to 3 strings at a time is used, but it is not enough to compress it by simply pressing it by hand, and even if it is tied with a rope, it can be compressed to a small volume. Can not do it. The latter device was produced by the applicant of the present application in response to requests from fishermen, and devices similar to this device are not commercially available, and there is no prior art document to be described in this application.

Accordingly, an object of the present invention is to provide an apparatus capable of compressing a plurality of culture materials at once and easily binding the compressed culture materials in a compressed state.

The present invention provides a compression device for compressing aquaculture material to reduce its volume. The apparatus includes a storage section for storing aquaculture materials and a compression section for compressing the aquaculture materials. The storage part has an opening through which a fastening member for binding the compressed aquaculture material can pass. The compression section has a compression member that compresses the aquaculture material by moving inside the storage section, and a feed mechanism that moves the compression member. The compression member has a groove at a location opposite the compressed aquaculture material into which a fastening member can be placed.

In one embodiment, the compression member has a retaining member overlying the groove for retaining the fastening member. The retaining member can retain the fastening member in the groove when no force is applied to the fastening member disposed in the groove in the direction of the compressed aquaculture material. The retaining member also allows the fastening member to be ejected from the groove when the fastening member is moved toward the compressed aquaculture material. In one embodiment, the holding member is preferably a door-like elastic body partially fixed to the compression member.

In one embodiment, at least the end portion of the storage portion opposite to the end portion in the direction in which the compression member moves when the aquaculture material is compressed is configured to be movable in a direction away from the movement axis of the compression member. It is preferable that This embodiment can include not only a configuration in which the housing portion is tilted, but also a configuration in which the housing portion is configured to move laterally while maintaining a posture without tilting. In another embodiment, only the end opposite to the direction in which the compression member moves when the aquaculture material is compressed can move away from the axis of movement of the compression member. More preferably. This embodiment is typically, but not limited to, a form in which the container is configured to tilt. Moreover, it is preferable that the accommodating portion is provided with an opening/closing portion in a portion positioned in the direction of the axis of movement of the compression member when it moves away from the axis of movement of the compression member.

According to the present invention, aquaculture materials having a large volume can be easily accommodated in the storage section, automatically compressed, and tied with a rope while maintaining the compressed state. It can be easily taken out from the housing. Therefore, even large-volume aquaculture materials can be easily and quickly compressed to a compact size, which facilitates storage and transportation.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 2 is an external perspective view of a compression device 1 for compressing and binding aquaculture material with fastening members according to one embodiment of the present invention. The aquaculture material is typically a seedling harvester used for fisheries, but it is not limited to this, and any material that has a large volume when in use but can be reduced in volume by compression. can be compressed using the apparatus. In the following, a mode of using a seedling collector as an aquaculture material will be described. In addition, although the fastening member can be a rope typically used in fishing applications, it is not limited to this. Any material that is difficult to unravel may be used. The compressing device 1 includes an accommodating portion 20 arranged on the bottom plate 12 inside the frame 10 and a compressing portion 40 arranged above the accommodating portion 20 .

The accommodation unit 20 has a space inside that can accommodate a plurality of resin-made seedling collectors N formed in a net shape (hereinafter, the plurality of seedling collectors will be referred to as “seedling collectors Ns”). . The housing portion 20 is formed as a substantially rectangular parallelepiped hollow box having a front surface 21a, side surfaces 21b and 21d, a rear surface 21c, and a bottom surface 21e. The housing portion 20 has an open upper surface, and a compressing member 41 of the compressing portion 40, which will be described later, can enter through the opened upper surface.

Although the accommodating portion 20 has a rectangular parallelepiped shape in this embodiment, it is not limited to this, and may have a columnar shape or other polygonal prismatic shape. However, if the seedling collecting device Ns after compression is a cube that is tightly bound with a rope, it will be difficult to release the compressed state even if it is thrown or otherwise handled during loading and unloading operations during transportation. Therefore, it is preferable that the shape of the compressed seedling collector Ns is a shape close to a cube. It is more preferable to have

The size of the storage unit 20 may be appropriately selected according to the size and number of the seedling collectors Ns to be compressed and the desired shape after compression. A suitable size to be used for compacting into the shape of (eg, a size for processing a triple seed picker Ns) is, for example, about 40 cm×about 45 cm×about 110 cm.

The opening/closing door 25 may have the same width as the rear surface 21c and a height of about 70% of the upper portion in the height direction of the rear surface 21c, although the opening/closing door 25 is not limited thereto. The opening/closing door 25 has a hinge on the lower side, and can be rotated around the hinge to open the opening of the rear surface 21c. By opening the opening/closing door 25 when the accommodating part 20 is tilted, an upward opening appears in the accommodating part 20, so that the accommodating part 20 accommodates the seedling collector Ns and the accommodating part of the seedling collector Ns after being compressed. The removal work from 20 becomes easier.

The open/close door 25 is preferably locked by a lock mechanism (lock plate 23a, projection 23b). In this embodiment, a lock plate 23a is attached to both ends of the rear handle 23. The lock plate 23a is provided with a lock groove 23a1 and is attached to the opening/closing door 25 so as to be rotatable about a shaft 23c. . On the other hand, a protrusion 23b is provided on the side surface 21b of the accommodating portion 20 at a position that can be engaged with the lock groove 23a1. With such a lock mechanism, when the lock groove 23a1 and the projection 23b are engaged with each other, the opening/closing door 25 is locked in a closed state, and the lock plate 23a is moved upward with the shaft 23c as a fulcrum, for example, the rear handle 23 is moved upward. The opening/closing door 25 can be opened by pushing it upward to rotate it and release the engagement between the lock groove 23a1 and the projection 23b.

Rope passage openings 26a, 26b, 26c, and 26d are provided in the lower portions of the front surface 21a and the rear surface 21c of the housing portion 20, respectively. The rope passing openings 26a to 26d are openings for passing the rope R that binds the compressed seedling harvester Ns after the seedling harvesting device Ns in the storage section 20 is compressed. The number of rope passing openings 26a to 26d is not particularly limited as long as it is provided according to the number of ropes R required to properly bind the compressed seedling extractor Ns, but at least two. It is preferable that two or more of each of the front surface 21a and the rear surface 21c are provided at suitable intervals so that the rope R of the book can be used. The length of the rope passing openings 26a-26d is not particularly limited as long as it is longer than the height of the compressed seedling picker Ns. Also, the width is not particularly limited as long as it is wider than the thickness of the rope R.

A compressing portion 40 is provided above the accommodating portion 20 . FIG. 3 illustrates the structure and function of compression section 40 according to one embodiment of the present invention. The compressing unit 40 has a compressing member 41 that enters from the opened upper surface of the accommodating unit 20 and moves downward to compress the seedling collector Ns, and a feed mechanism 42 that moves the compressing member 41 up and down. . The compressing portion 40 is preferably supported by the top plate 11 arranged above the accommodating portion 20 .

The compression member 41 can be vertically moved by a feed mechanism 42 . As the feed mechanism 42, for example, a general mechanism using a trapezoidal screw, a ball screw, or the like can be appropriately used according to need. a nut (not shown) positioned on the nut, a trapezoidal screw 43 that moves longitudinally as the nut rotates, and a motor 45 that rotates the nut. The operation of the feeding mechanism 42 can be started or stopped by a button or the like provided on the operation section 46 .

The compression member 41 is attached to the lower end of the trapezoidal screw 43 and has a press plate 47 that contacts and compresses the seedling collector Ns in the storage section 20 . The pressing plate 47 has, on its upper surface, a rope-passing groove 48 through which a rope R for tying the compressed seedling collector Ns can be passed between the opposing sides. The rope penetration groove 48 is open in the direction of the seed picker Ns to be compressed. The number of rope penetration grooves 48 is not particularly limited as long as it is provided according to the number of ropes R for appropriately binding the compressed seedling collector Ns, but at least two ropes R are provided. More than two are preferred so that they can be used. The width and depth of the rope penetration groove 48 should be such that at least the rope R can be passed through the groove.

As shown in FIG. 3(b), the rope penetration groove 48 is preferably covered with a plate 49 at a portion open in the direction of the compressed seedling collector Ns. The plate 49 is wider than the width of the rope penetration groove 48 and has a length approximately equal to the length of the rope penetration groove 48, one end in the width direction is fixed to the press plate 47, and the other end in the width direction is fixed to the door. It is made of an elastic material so that it can be opened in a shape. The plate 49 is made of a material that allows the rope R to slide easily so that when the rope R is passed through the rope penetration groove 48, the tip of the rope R moves smoothly in the groove and does not get stuck inside. Preferably. The plate 49 can be, for example, a door-shaped elastic body made of rubber or a door-shaped elastic body made of resin.

The plate 49 is preferably made of a single sheet of material that covers the entire length of the rope through groove 48, but is not limited to this. It may be composed of a plate, or it may be composed of a plurality of plates each partially covering the length direction of the rope through groove 48 . The plate 49 can also be formed of two pieces of material that cover the entire length, brought together at the widthwise central portion of the rope through-channel 48 . When these two materials are used, the widthwise ends of the two materials (the ends of the two materials farther from each other) are fixed to the press plate 47, and the widthwise central portion of the rope through groove 48 is connected to the door. It can be configured to open like a

Plate 49 functions as shown in FIGS. 3(b)-3(d). When the rope R is passed through the rope through groove 48 and no force is applied to the rope R, the rope R is held in the rope through groove 48 by the plate 49 as shown in FIG. 3(b). That is, the plate 49 functions as a holding member for the rope R. When the rope R is moved in the direction of the compressed seedling collector N, a force in that direction is applied to the plate 49, so the plate 49 fixed at only one end is pushed by the rope R and opens like a door. The rope R begins to be discharged from the rope penetration groove 48 (Fig. 3(c)). When a force is further applied to the rope R in the same direction, the rope R is completely ejected from the rope penetration groove 48 and placed on the upper surface of the compressed seedling collector Ns, and the plate 49 is moved again to the open portion of the rope penetration groove 48. (Fig. 3(d)).

Next, the process of compressing the seedling collector Ns in the compressing device 1 according to one embodiment of the present invention will be described. FIG. 4 is a schematic diagram for explaining the process of accommodating and compressing the seedling collector. Before the seedling collector Ns is placed in the storage section 20, the compression section 40 is operated so that the compression member 41 is positioned above the storage section 20 (Fig. 4(a)).

Next, the front handle 22 of the housing portion 20 is pulled to tilt the housing portion 20 (FIG. 4(b)). At this time, the housing part 20 has an end (that is, , upper end in FIG. 4(a)) move away from the axis of movement of the compression member 41 (i.e., the longitudinal extension of the trapezoidal screw 43 in FIG. 4(a)), i.e., the housing 20 tilts with the hinge 24 as a fulcrum.

After tilting the accommodating portion 20, the lock groove 23a1 of the lock plate 23a is removed from the protrusion 23b, and the opening/closing door 25 is opened (FIG. 4(c)). The opening/closing door 25 is provided in a portion of the accommodation portion 20 located in the direction of the movement axis of the compression member 41 . The seedling collector Ns is accommodated in the accommodating part 20 from the part where the opening/closing door 25 is opened. When the opening/closing door 25 is opened, the U-shaped housing portion 20 appears, and by arranging the individual seedling collectors N there in order, the plurality of seedling collectors Ns can be efficiently accommodated. As a result, the compressed seedling collector Ns can be arranged in a substantially rectangular parallelepiped shape.

After storing the seedling collector Ns, the opening/closing door 25 is closed, the lock groove 23a1 of the lock plate 23a is engaged with the protrusion 23b, and the storage section 20 is returned to its original position (Fig. 4(d)). After that, by operating the operation part 46 to operate the compressing part 40, the compressing member 41 moves downward inside the housing part 20, compressing the seedling collector Ns (FIG. 4(e)).

Next, the process of binding the compressed seedling collector Ns will be described. FIG. 5 is a schematic diagram for explaining the process of tying the compressed seedling collector. In order to simplify the drawing, the seedling collector Ns is not drawn in FIG.
The accommodating portion 20 is provided with rope passing openings 26a to 26d for passing the rope R therethrough.

Before the seedling collector Ns is housed in the housing part 20, preferably in the state of FIG. and 26c, another rope R is arranged.

After the seedling collecting device Ns is housed in the housing portion 20 (FIGS. 4C and 4D) and compressed by the compressing member 41 (FIG. 4E), the compressing member 41 compresses the collected seedlings. It is positioned on the upper surface of the container Ns (FIG. 5(b)). In this state, the two ropes R previously passed through the rope passing openings 26a to 26d are respectively passed through the rope passing grooves 48 of the compression member 41 as shown in FIG. 5(c). Each of the two ropes R has one end appearing in front of the front surface 21a from the bottom of the rope passage openings 26a and 26b, and the other end appearing in front of the front surface 21a from the top of the rope passage openings 26a and 26b. state.

Next, when the operator applies force to the two ropes R passed through the rope penetration groove 48 by holding, for example, a portion on the front surface 21a side and a portion on the rear surface 21c side, the ropes R are compressed. It moves in the direction of the seed picker Ns. At this time, as shown in FIGS. 3(c) and 3(d), the rope R opens the plate 49, which is configured such that one end is fixed and the other end is open, like a door, and the rope penetration groove is opened. 48 is discharged. The part of the rope R discharged from the rope penetration groove 48 is arranged on the compressed seedling collector Ns so as to extend in the front-rear direction.

Finally, as shown in FIG. 5(d), the operator binds the two ropes R in front of the front surface 21a, and then raises the compression member 41 toward its original position. The seedling collector Ns compressed and bound by the two ropes R can be easily removed from the container 20 by tilting the container 20 as shown in FIG. can be done.
