Description

The present invention relates to a compression device for compressing a resin net-like aquaculture material used for culturing cultivated mussels to reduce the volume.

Scallop larvae can be collected by attaching scallop larvae to a seedling collector. As shown in FIG. 1A, the seedling collector N can be produced by combining two types of resin nets (generally called "netron nets") having different mesh sizes, for example, a small mesh. It is obtained by pushing an inner bag having a larger mesh than the outer bag into the outer bag and closing both ends of the outer bag to form an overall bulging shape. As shown in FIG. 1 (b), 15 to 20 sets of seedling collectors N (generally called "lanterns") produced in this way are connected as one set, and these are connected. 30 to 40 seedling collectors are put into the sea as a single unit (plural number of seedling collectors Ns). The number of seedling collectors Ns to be put into the sea varies depending on the region and production volume, but for example, in the vicinity of Lake Saroma, 300 to 500 seedling collectors Ns will be put into the sea. The seedling collector Ns thrown into the sea are landed several months later, and the scallop juveniles separated from the seedling collector Ns are replaced with a Zabton basket or the like. The seedling collector Ns from which the scallop juveniles have been removed is washed and stored until the next time it is put 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 collector Ns is about 2 kg at most, but the volume of the series of seedling collector Ns fits in the loading platform of the light truck. It will not be the size. Therefore, aquaculture materials consisting of 30 to 40 seedling collectors Ns as one station and a total of 300 to 500 stations occupy a large area during storage as they are, so securing a storage place is a problem. Become. In addition, it is difficult to handle aquaculture materials having a large volume when they are transported by truck from the storage location to the fishing boat or when they are loaded on the fishing boat. Furthermore, aquaculture materials with a large volume are complicated because the amount that can be loaded on a fishing boat is limited and work such as tying them so that they do not fall into the sea during navigation is required.

Traditionally, fishermen push the aquaculture material into a handmade wooden box, press it down, compress it, and tie it with a rope to reduce the volume, or use a hand-push press device made for the purpose of reducing the volume of the aquaculture material. By doing so, we have addressed the issue of aquaculture material volume. For the former wooden box, a wooden box that can hold 2 to 3 stations at a time may be used, but compression is insufficient just by pressing it by hand and compressing it, and even if it is tied with a rope, it is compressed to a small volume. Can not do it. The latter device was manufactured by the applicant of the present application at the request of the fisherman, and no device similar to such a device is commercially available, and there is no prior art document to be described in the present application.

Therefore, it is an object of the present invention to provide an apparatus capable of compressing a plurality of aquaculture materials at a time and easily binding the compressed aquaculture materials in a compressed state.

The present invention provides a compression device for compressing aquaculture materials to reduce their volume. This device includes a storage unit for accommodating the aquaculture material and a compression unit for compressing the aquaculture material. The containment section has an opening through which a fastening member for binding the compressed aquaculture material can be passed. The compression unit has a compression member that compresses the aquaculture material by moving inside the storage unit, and a feeding mechanism that moves the compression member. The compression member has a groove in which the fastening member can be arranged at a position facing the compressed aquaculture material.

In one embodiment, the compression member has a holding member for holding the fastening member so as to cover the groove. The holding member can hold the fastening member in the groove when no force is applied to the fastening member arranged in the groove in the direction of the compressed aquaculture material. In addition, the holding member can discharge the fastening member from the groove when the fastening member is moved in the direction of the compressed aquaculture material. In one embodiment, the holding member is preferably a door-shaped elastic body partially fixed to the compression member.

In one embodiment, the accommodating portion is configured so that at least the end opposite to the end in the direction in which the compression member moves when the aquaculture material is compressed can move in the direction away from the movement axis of the compression member. It is preferable that it is. This embodiment can include not only a form in which the accommodating portion is configured to be tilted, but also a form in which the accommodating portion is configured to move laterally while maintaining a posture without being tilted. In another embodiment, the accommodating portion allows only the end opposite to the end in the direction in which the compression member moves when the aquaculture material is compressed to move away from the movement axis of the compression member. It is more preferable that it is configured. This embodiment is not limited to, but is typically configured such that the accommodating portion is tilted. Further, it is preferable that the accommodating portion is provided with an opening / closing portion at a portion located in the direction of the moving axis when the compression member is moved away from the moving axis.

According to the present invention, it is possible to easily accommodate a large-volume aquaculture material in a storage portion, automatically compress it, and tie it with a rope while maintaining the compressed state. It can be easily removed from the housing. Therefore, even a large-volume aquaculture material can be easily and quickly compressed to a compact size, which facilitates storage and transportation.

It is a schematic diagram which shows the process of binding a compressed seedling collector in the compression apparatus by one Embodiment of this invention.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a perspective view of the appearance of the compression device 1 for compressing the aquaculture material and binding it with the fastening member according to the embodiment of the present invention. The aquaculture material is typically a seedling collector used for fishery purposes, but is not limited to this, and may be a material that has a large volume in the used state but can be reduced in volume by compression. For example, it can be compressed using this device. In the following, the form when the seedling collector is used as the aquaculture material will be described. Further, as the fastening member, a rope typically used for fishery applications can be used, but the fastening member is not limited to this, and the compressed material can be firmly tied and easily tied even after being tied. Any member that is difficult to unravel may be used. The compression device 1 includes an accommodating portion 20 arranged on the bottom plate 12 inside the frame body 10 and a compression unit 40 arranged above the accommodating portion 20.

The accommodating portion 20 has an internal space capable of accommodating a plurality of resin seedling collectors N formed in a net shape (hereinafter, the plurality of seedling collectors are referred to as “seedling collectors Ns”). .. The accommodating portion 20 is formed as a hollow box body having a substantially rectangular parallelepiped shape and having a front surface 21a, side surfaces 21b and 21d, a rear surface 21c, and a bottom surface 21e. The upper surface of the accommodating portion 20 is open, and the compression member 41 of the compression portion 40, which will be described later, can be inserted into the inside from the open upper surface.

The accommodating portion 20 has a rectangular parallelepiped shape in the present embodiment, but is not limited to this, and may have a cylindrical shape or another polygonal column shape. However, if the compressed seedling collector Ns is a cube tightly tied with a rope, the compressed state is difficult to be released even if it is handled such as being thrown during loading and unloading work during transportation. Therefore, the shape of the compressed seedling collector Ns is preferably a shape close to a cube, and in order to obtain a cube having such a shape, the accommodating portion 20 has a rectangular parallelepiped shape having a bottom surface having a shape close to a square. More preferably.

The size of the accommodating portion 20 may be appropriately selected depending on the size and number of the seedling collector Ns to be compressed and the desired shape after compression, but the seedling collector Ns usually used by scallop farmers is generally a cube. The size suitable for use for compressing into the shape of (for example, the size for processing a triple seedling collector Ns) is, for example, about 40 cm × about 45 cm × about 110 cm.

It is preferable that the front surface 21a of the accommodating portion 20 is provided with a front handle 22 extending in a direction crossing the front surface 21a, and the rear surface 21c is provided with a rear handle 23 extending in a direction crossing the rear surface 21c. By pulling the front handle 22, the accommodating portion 20 can be easily tilted forward (to the left in FIG. 2) with the hinge 24 as a fulcrum. See). Further, by pulling the rear handle 23, the tilted accommodating portion 20 can be easily returned to the original position. Since the accommodating portion 20 can be tilted, it becomes easy to accommodate the bulky seedling collector Ns in the accommodating portion 20 and take out the compressed seedling collector Ns from the accommodating portion 20. The angle at which the accommodating portion 20 can be tilted is not particularly limited, but is about 40 degrees as an angle at which the accommodating portion 20 can be easily tilted and returned, and the seedling collector Ns can be accommodated and taken out. Is preferable

In the present embodiment, the accommodating portion 20 is configured to be tilted, but in another embodiment, a rail mechanism is arranged between the bottom surface 21e of the accommodating portion 20 and the bottom plate 12, and the accommodating portion 20 is arranged. The front handle 22 may be pulled to move toward the outside of the frame 10 while maintaining the initial posture without tilting.

It is preferable that the rear surface 21c of the accommodating portion 20 is provided with an opening from the upper side to a position of about 70% in the height direction, and the opening / closing door 25 is provided in the opening. The opening / closing door 25 may have the same width as the width of the rear surface 21c, and may have a height of about 70% of the upper portion of the rear surface 21c in the height direction, although not limited thereto. The opening / closing door 25 has a hinge on the lower side, and the opening of the rear surface 21c can be opened by rotating the opening / closing door 25 with the hinge as a fulcrum. By opening the opening / closing door 25 when the accommodating portion 20 is tilted, an upward opening appears in the accommodating portion 20, so that the accommodating portion 20 can accommodate the seedling collector Ns and the compressed seedling collector Ns accommodating portion. The work of taking out from 20 becomes easier.

The opening / closing door 25 is preferably locked by a locking mechanism (lock plate 23a, protrusion 23b). In this embodiment, lock plates 23a are attached to both ends of the rear handle 23, and the lock plate 23a is provided with a lock groove 23a1 and is rotatably attached to the opening / closing door 25 with the shaft 23c as a fulcrum. .. On the other hand, the side surface 21b of the accommodating portion 20 is provided with a protrusion 23b at a position where it can engage with the lock groove 23a1. By such a locking mechanism, when the lock groove 23a1 and the protrusion 23b are engaged, 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 upward. The opening / closing door 25 can be opened by rotating the lock groove 23a1 and disengaging the protrusion 23b by pushing it up.

The front surface 21a and the rear surface 21c of the accommodating portion 20 are provided with rope through openings 26a, 26b, 26c, and 26d below them. The rope through openings 26a to 26d are openings for passing the rope R that binds the compressed seedling collector Ns after the seedling collector Ns in the accommodating portion 20 is compressed. The number of rope through 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 collector Ns, but is at least 2. It is preferable that two or more ropes R are provided at opposite positions of the front surface 21a and the rear surface 21c at appropriate intervals so that the rope R of the book can be used. The length of the rope through openings 26a to 26d is not particularly limited as long as it is longer than the height of the compressed seedling collector Ns. Further, the width is not particularly limited as long as it is wider than the thickness of the rope R.

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

The compression member 41 can be moved up and down by the 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 as needed. In the present embodiment, the inside of the nut box 44 fixed to the top plate 11 It may have a nut (not shown) arranged in, a trapezoidal screw 43 that moves in the length direction according to the rotation of the nut, and a motor 45 that rotates the nut. The operation of the feed mechanism 42 can be started or stopped by a button or the like provided on the operation unit 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 accommodating portion 20. The press plate 47 has a rope through groove 48 on its upper surface through which a rope R for binding the compressed seedling collector Ns can be passed between the opposite sides. The rope through groove 48 is open in the direction of the seedling collector Ns to be compressed. The number of rope through 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. It is preferably two or more so that it can be used. The width and depth of the rope through groove 48 may be at least as long as the rope R can be passed through the groove.

As shown in FIG. 3B, it is preferable that the portion of the rope through groove 48 that is open in the direction of the compressed seedling collector Ns is covered with the plate 49. The plate 49 is wider than the width of the rope through groove 48 and has a length similar to the length of the rope through groove 48, one end in the width direction is fixed to the press plate 47, and the other end in the width direction is the door. It is formed by an elastic body so as to open like a rope. The plate 49 is made of a material that makes it easy for the rope R to slide so that when the rope R is passed through the inside of the rope through groove 48, the tip of the rope R moves smoothly in the groove and does not get clogged inside. It is preferable to have. The plate 49 can be, for example, a rubber door-shaped elastic body or a resin door-shaped elastic body.

The plate 49 is preferably formed of a single material that covers the entire length of the rope through groove 48, but is not limited to this, and a plurality of plates 49 that cover the entire length of the rope through groove 48. It may be composed of plates, or may be composed of a plurality of plates, each of which partially covers the length direction of the rope through groove 48. Further, the plate 49 can also be formed of two materials that are aligned at the central portion of the rope through groove 48 in the width direction and cover the entire length direction. When these two materials are used, the end portions in the width direction (the ends of the two materials far from each other) are fixed to the press plate 47, and the door is opened from the center portion in the width direction of the rope through groove 48. It can be configured to open like a rope.

The plate 49 functions as shown in FIGS. 3 (b) to 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 that the plate 49 having only one end fixed is pushed by the rope R and opens like a door. The rope R begins to be discharged from the rope through groove 48 (FIG. 3 (c)). Further, when a force in the same direction is applied to the rope R, the rope R is completely discharged from the rope through groove 48 and rests on the upper surface of the compressed seedling collector Ns, and the plate 49 is again an open portion of the rope through groove 48. It returns to the original position so as to cover the rope (Fig. 3 (d)).

Next, the step of compressing the seedling collector Ns in the compression device 1 according to the embodiment of the present invention will be described. FIG. 4 is a schematic view for explaining a process of accommodating and compressing a seedling collector. Before inserting the seedling collector Ns into the accommodating unit 20, the compression unit 40 is operated so that the compression member 41 is located above the accommodating unit 20 (FIG. 4A).

Next, the front handle 22 of the accommodating portion 20 is pulled to tilt the accommodating portion 20 (FIG. 4 (b)). At this time, the accommodating portion 20 has an end portion (that is, an end portion opposite to the end portion in the direction in which the compression member 41 moves when the seedling collector Ns is compressed (that is, the lower end portion in FIG. 4A)). , The upper end in FIG. 4A) moves away from the moving axis of the compression member 41 (that is, the extension of the trapezoidal screw 43 in the length direction in FIG. 4A), that is, the accommodating portion. 20 will tilt with the hinge 24 as the fulcrum.

After tilting the accommodating portion 20, the lock groove 23a1 of the lock plate 23a is removed from the protrusion 23b to open the opening / closing door 25 (FIG. 4C). The opening / closing door 25 is provided at a portion of the accommodating portion 20 located in the direction of the moving axis of the compression member 41. The seedling collector Ns is accommodated in the accommodating portion 20 from the portion where the opening / closing door 25 is opened. When the opening / closing door 25 is opened, a U-shaped accommodating portion 20 appears. Therefore, by arranging the individual seedling collectors N in order, it is possible to efficiently accommodate a plurality of seedling collectors Ns. As a result, the compressed seedling collector Ns can be arranged into a substantially rectangular parallelepiped shape.

After accommodating 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 accommodating portion 20 is returned to the original position (FIG. 4D). After that, by operating the operation unit 46 to operate the compression unit 40, the compression member 41 moves downward inside the storage unit 20, and the seedling collector Ns is compressed (FIG. 4 (e)).

Next, the step of binding the compressed seedling collector Ns will be described. FIG. 5 is a schematic diagram for explaining a process of binding the compressed seedling collector. In addition, in order to simplify the figure, the seedling collector Ns is not drawn in FIG.
The accommodating portion 20 is provided with rope through openings 26a to 26d for passing the rope R. As shown in FIG. 5A, the rope through openings 26a and 26d are provided to face each other and the rope through openings 26b and 26c are provided to face each other on the front surface 21a and the rear surface 21c of the accommodating portion 20. .. Before the seedling collector Ns is accommodated in the accommodating portion 20, preferably in the state of FIG. 4A, one rope R is arranged in the rope through openings 26a and 26d, and similarly, the rope through openings 26b. And another rope R is placed at 26c.

After the seedling collector Ns is accommodated in the accommodating portion 20 (FIGS. 4 (c) and 4 (d)) and compressed by the compression member 41 (FIG. 4 (e)), the compression member 41 is compressed for seedling collection. It is located on the upper surface of the vessel Ns (FIG. 5 (b)). In this state, the two ropes R previously passed through the rope through openings 26a to 26d are each passed through the rope through groove 48 of the compression member 41 as shown in FIG. 5 (c). One end of each of the two ropes R appears from the lower part of the rope through openings 26a and 26b in front of the front surface 21a, and the other end appears from the upper part of the rope through openings 26a and 26b in front of the front surface 21a. It will be in a state of being.

Next, when the operator exerts a force on the two ropes R passed through the rope through groove 48 by holding, for example, a portion on the front surface 21a side and a portion on the rear surface 21c side, the rope R is compressed. Move in the direction of the seedling collector Ns. At this time, as shown in FIGS. 3 (c) and 3 (d), the rope R opens a plate 49 having a structure in which one end is fixed and the other end is opened in a door shape, and the rope through groove is formed. It is discharged from 48. The portion of the rope R discharged from the rope through groove 48 will be arranged on the compressed seedling collector Ns so as to extend in the front-rear direction.

Finally, the operator ties the two ropes R in front of the front surface 21a, as shown in FIG. 5D, and then raises the compression member 41 back to its original position. The seedling collector Ns, which has been compressed and bound by two ropes R, can be easily taken out from the accommodating portion 20 by tilting the accommodating portion 20 as shown in FIG. 4 (c) and opening the opening / closing door 25. Can be done.
