Description

[Detailed Description of the Invention] The raising of nets, such as fixed nets, is done exclusively by manual labor, but a method of doing this mechanically is to bite the net between two pneumatic rubber tires called a catch hauler. Alternatively, several cars can be run vertically along the sides and bottom of the box net, branch ropes are attached to the cars at appropriate intervals, the other end is fixed to the net, and a winch is used. There are some net lifting machines that pull the net to pull it up, but all of these net lifting machines tend to apply force to only one part of the net, which can cause the net to break. In particular, the friction between the rubber tires of the net lifter and the net can easily damage the net, and there is a danger that if you are not careful, your body may get caught in the net along with the net.

The present invention has been devised and developed to solve the above-mentioned problems, and an example of implementing the present invention will be described below based on the accompanying drawings.

FIG. 1 is an overall perspective view showing an example of a fixed net, in which 1 is a fence net, 2 is an enclosure net (playground), and 3 is a box net. In this case, fence net 1 is used to block the fishway and prevent the fish school from changing its course, and line 2 surrounds the guided fish school within a certain range, restricting its movement, and finally creates a box for catching fish. They are guided by a net, and the manner in which the net is installed is the same as in the prior art, but in the present invention, the box set 3 in particular has a configuration as shown in FIG.

That is, in the present invention, a plurality of inner nets 4a, 4b4C...
・In addition, each inner net 412,
4b, 44, . . . have a chino 6 with U-shaped sources 5 integrally attached every several pitches (2 pitches in the illustrated example).
A fastening string 7 is used to secure it integrally. At this time, the starting end m of each inner net 4a, 4b, 4c, etc. is attached to the fish catching part 3b, and the end n is attached to the funnel part 3.
[The inner layer near the bottom end is about 3d [This is because it is temporarily bound to the sieve.]

FIG. 3 shows the net lifting machine 10 used in the present invention, with A being a partially cutaway front view and 8 being a side view C. child\
Reference numeral 11 denotes a chain wheel, which is rotatably supported between a pair of side plates 12. are connected to each other so that they can be rotated together by the operation of the motor. ■ 4.14° is a chain guide provided so as to cover the lower semicircumference of the chain wheel 11, and each tip l has a pin 15 at the center position of the inner edge of each side plate 12.12'. The chain guides 14 and 141 can pass through the chain wheel 11 while sandwiching the chain wheel 6 and the U-shaped source 5 integrally attached to the chain wheel 6. Gaps q and r are formed, and the rear end f of each chino guide is made to protrude slightly horizontally from the side plate, and it is configured to be fixed to the back using a pin 16, which can be freely attached and detached. .

In the present invention, the net lifting machine constructed as described above can be used to lift at least as many inner nets as the number of inner nets provided on the bottom surface 3d of the box net on one side of the ship, while maintaining the distance H between them. The support bracket 17 (L-) is disposed so as to protrude from the side of the ship.

Figure 4 is an explanatory view of the action, A is a front view during net raising, B
is a detailed partial X-X diagram of A; Net raising is a process to bring the school of fish that have fallen into the box net into the boat.
Position the ship 18 near the boundary of the net 3, and hold the upper edge of the net 3, which is initially floating on the sea, and move it to the funnel rope section 3C.
This means that they are brought into the ship manually. There is no problem with this skillful work even if it is done manually, and the funnel rope section 3C is taken into the boat to seal off the entrance of the fish. The ends of each of the temporarily fastened ropes are removed, and the chains of each inner net are engaged with the chain wheels of each net lifting machine attached to one side of the ship.

For this engagement, first remove the pin 16, make the chain guides 14 and 14' hang down, and insert the ends of the blade sets, as well as connect several chains 6 in each inner mesh. The pin 16 is inserted into the recessed part (2) of the chain wheel, and then the chain guide 14, 14' is pulled up and the pin 16 is inserted and fixed as before. At this time, the end of the rope should be temporarily secured again to its original position.

When the engagement work for each net hoist 10 is completed in this way, the funnel rope section 3C taken into the ship is returned to the sea, and the hydraulic pump is operated from inside the ship to activate the hydraulic motor 13 of each net hoist. The chain wheel 11 of each net lifting machine is rotated at a predetermined rotational speed according to the waste.
) direction to mechanically perform the entire net raising operation, and gradually drive the school of fish in the box net toward the fish catching section 3bVc.

The present invention is constructed as described above, that is, the chain wheel is rotated by a hydraulic motor, and the chain wheel is engaged with the chain wheel to raise the car and net attached to the chain.
After one fish is caught, the net is reliably lifted, and during that time, the hydraulic motor's torque adjustment, speed change, forward/reverse operation, sudden stop, and inching can be freely controlled remotely. It is also possible to centrally control the netting equipment, which greatly contributes to labor savings.

Next, the fact that the chain 6 is attached to the car 4 means that when lifting the net, the lifting force of the chain 6 is applied to the entire area where it is attached to the net, so the net is not forced and the net breaks. It is something without. Furthermore, since the method does not involve directly pulling up the fabric using frictional force, damage to the fabric is naturally prevented.

The net lifting machine 10 has a simple structure, is easy to manufacture, is inexpensive, is easy to install, and is relatively easy to operate. Therefore, it is easy to install on any small fishing boat, contributing to labor saving and dramatic improvement in work performance.

On the other hand, the fact that the cheno is attached to the net bottom car makes it less likely to deform due to the weight of the cheno even in strong currents compared to conventional ones, making it easier for fish to enter, or even when there is a slight current. This makes it possible to smoothly raise the net regardless of the situation.

On the other hand, the weight of Cheno makes it possible to use fiber nets with a lower specific gravity than the nets conventionally used for fixed nets, which not only makes it easier to handle the net as a whole, but also
This will lead to a reduction in price. At this time, the weight of the entire net may be adjusted by using a combination of steel, stainless steel, nylon, or other synthetic materials as the material of the chain.

In the above embodiment, a case has been described in which the cheno is integrally fixed to the rope through the 0-shaped ring, but depending on the size and shape of the cheno, the 0-shaped ring is not necessarily secure.

In the above embodiments, a fixed net was explained, but the present invention can also be applied to gill nets, rod nets, turning nets, etc. In other words, although not shown in the drawings, in a l1zU net, a float net can be used. For the side ropes and sinking ropes, for pole nets, several lines are installed inside the net, and for purse nets, several lines are installed at the fishing station. It can be similarly carried out by integrally attaching a check to these ropes and force #14 through or without using a KU-shaped ring for each assault pitch. shall be.
