Description

  The present invention relates to a fishing machine and a fishing device, and more specifically, a fishing machine for fishing various fish such as sword fish, yellowtail, sawara, and Thailand that live in the deep sea at a depth of about 60 to 100 m and the fishing machine. This invention relates to a fishing device using

  In general, sword fish, yellowtail, sawara, and Thailand live in the deep water at a depth of about 60 to 100 m, and use fishing instead of fish nets so as not to damage the epidermis during the fishing process. In the conventional fishing method, a heavy weight is hung from a fishing line connected to a plurality of fishhooks and dropped into the seawater. The fishline is gripped by hand and whether or not a fish such as a sword fish is caught by the fishhook is pulled by hand. Judging by feeling, if it can be determined that a certain number of fish have been caught, the fishing line is pulled up with a fishing machine. Usually, if it can be determined that about 5 fish have been caught in one fishing line, the fishing line is pulled up.

  By the way, because the number of fish caught on the hook is judged by using only the sense of the hand in this way, even though only one or two fish are actually caught, more than that There are cases where it is mistaken that a number of fish have been taken and the fishing line is pulled up. In this case, it is not possible to catch a plurality of fish in one operation, resulting in a decrease in operation efficiency.

  Moreover, the conventional fishing machine has only a function of raising or lowering the fishing line using a motor, and visually judges the degree of vertical movement of the fishing line, and manually controls the fishing machine. For this reason, not only the operation efficiency is lowered, but also the degree to which the fishing line is lowered is erroneously determined, and the method for lowering the fishing line may be insufficient or excessive, and the fish may not be removed.

  Furthermore, since the conventional fishing machine forcibly releases the fishing line by rotating the motor when the fishing line is lowered, does the fishing line get tangled because the speed at which the fishing line descends into the seawater and the speed at which the fishing machine can unwind? In some cases, the bait that is left for fishing may be removed.

FIG. 2 is a block diagram showing a fishing apparatus in a state where a fishing line is pulled up according to an embodiment of the present invention.

  The fishing apparatus of the present embodiment is fixed on a ship deck, for example. The fishing device includes a fishing rod 11 used to estimate the number of fish caught on the fishhook by the degree of curvature, an auxiliary fishing line 12 connected to the tip of the fishing rod 11, and an auxiliary weight connected to the tip of the auxiliary fishing line 12. 14 and an auxiliary device composed of a small ring 13 connected to the lower end of the auxiliary weight 14. This auxiliary device is a means for estimating with the naked eye how many fish have caught the fishhook 32, which will be described later, based on the degree of curvature of the fishing rod 11.

  The fishing rod 11 is made of, for example, bamboo, and has a length such that when a fish or the like is caught on the fishhook 32, the extent to which it is caught (number of animals, etc.) can be estimated. It preferably has a length of 6 m.

  The small ring 13 is made of steel, for example, and the weight 14 is made of lead, for example. The weight of the weight 14 is preferably about 50 g. The auxiliary fishing line 12 preferably has a length that allows the weight 14 to be slightly immersed in seawater in an actual installation state (for example, a state where the fishing line shown in FIG. 1 is lowered).

  The fishing device according to the present embodiment includes a fishing line 30 lowered in seawater for fishing sword fish, a weight 31 connected to the tip of the fishing line 30, the degree to which the fishing line 30 is lowered in seawater, and the fishing line 30. In order to limit the degree of pulling up, they are connected to the lower part and the upper part of the fishing line 30, respectively, and are connected between two balls 33a, 33b having an outer diameter larger than the inner diameter of the small ring 13, the weight 31 and the ball 33a. In order to move up and down the plurality of fishhooks 32 and the fishing line 30, a fishing machine 100 installed in a ship is provided.

  The weight 31 is preferably made of lead, for example, and has a weight of about 800 g. The fishing line 30 extends through the small ring 13 with a length of 100 m or more so that it can be operated even in the sea at a depth of 60 to 100 m. The fishhook 32 is connected to the fishing line 30 reaching about 40 m between the weight 31 and the lower ball 33a. In this embodiment, about 15 fishhooks 32 are connected at regular intervals.

  The balls 33a and 33b have a through hole (not shown) formed in the center, and the fishing line 30 is passed through the through hole. Since the outer diameters of the balls 33 a and 33 b are larger than the inner diameter of the small ring 13, the balls 33 a and 33 b cannot pass through the small ring 13.

The electromagnetic clutch 104 rotates through the output shaft 103a of the speed reducer 103, the tip of the output shaft 103a is supported by a bearing 106, and the rotating shaft 109 of the drum 101 has bearings 109a at both ends thereof. 109b is rotatably supported.

  The fishing machine 100 according to the present embodiment includes a fishing line raising / lowering adjustment system in order to control the lowering degree (length) and the raising degree (length) of the fishing line 30. This fishing line raising / lowering adjustment system includes, for example, a worm speed reducer 110, an electromagnetic brake 120, a rising plate 134, a cam 112a, a rising adjustment handle (knob) 132, a lowering plate 135, a cam 112b, a lowering adjustment handle (knob) 133, and a water depth plate. 130, the indicator 131 etc. are comprised.

  In the worm speed reducer 110, the rotary shaft 109 of the drum 101 and the input shaft 111 are connected via the chain 108 and receive a rotational force, and the rotational speed of the rotary shaft 109 is greatly reduced. The output shaft 112 extends in a direction perpendicular to the input shaft 111. The electromagnetic brake 120 brakes the rotation of the input shaft 111 of the worm reducer 110.

The lowering adjustment handle 133 has a sprocket formed at the rear end so as to be connected to the sprocket of the lowering plate 135 via a chain 137, and is installed on a front plate rotatably attached to the front plate. .

  The water depth plate 130 is provided on the front plate, and a scale indicating the water depth is displayed in an annular shape. The indicator 131 is attached to the tip of the output shaft 112 of the worm speed reducer 110 penetrating the center portion of the deep water plate 130.

  A worm and a worm wheel are provided inside the worm reducer 110, and a gear train for adjusting the reduction ratio between the input shaft 111 and the output shaft 112 is formed outside the worm reducer 110. The output shaft 112 determines the reduction ratio so as to rotate within one rotation.

  The water depth value is displayed on the water depth plate 130 from 0 to 75 m in the circumferential direction, but this range can be changed. As described above, the cams 112a and 112b and the indicator 131 are fixed to the output shaft 112 of the worm reducer 110 so as to rotate together, but the snap rings, keys, screws, etc. for fixing them are not shown. did. A means for allowing relative rotation such as a bearing can be provided between the output shaft 112 and the ascending plate 134 and the descending plate 135, but this is also omitted.

  A selection switch 140 for selecting ascending on, descending on, or off is arranged on the front plate of the box of the fishing machine 100, and an ascending button 141 and a descending button for operating the system only while the button is pressed. 142 is provided. Further, a rising lamp 143 that is lit while the fishing line 30 is raised and a lowering lamp 144 that is lit while being lowered are arranged.

  It should be noted that a mechanism for applying a rotational force to the drum 101 such as the motor 102, the speed reducer 103, the electromagnetic clutch 104, the chain 105, the sprocket 107, and the rotating shaft 109, and a fishing line lifting and lowering adjustment system such as the worm speed reducer 110 and the electromagnetic brake 120. A portion is placed in the enclosure. Moreover, a housing has a front plate | board with which various operators and a display machine of a fishing line raising / lowering adjustment system are arrange | positioned.

  The fishing apparatus of the present embodiment configured as described above operates as follows.

  First, in the fishing line 30 penetrating the small ring 13, the lower ball 33a is tied to the lower position about 40m away from the weight 31, and the upper ball 33b is tied at an appropriate position above the small ring 13 depending on the water depth. The fishing line 30 is wound around the drum of the fishing machine 100. The distance between the lower ball 33a and the upper ball 33b is, for example, about 35 m when the water depth is 70 m. And as shown in FIG. 1, the fishing rod 11 is installed and the fishing line 30 of the part with which the weight 31 and the fishhook 32 were connected is dropped in the sea.

  In this state, the descent adjustment handle 133 of the fishing machine 100 is turned to adjust the descent length of the fishing line 30. Under the above-described conditions, the descent restriction display is made in view of the distance between the upper ball 33b and the fishing machine 100. The vessel 135b points to the scale 70m of the deep water plate 130. When the lowering adjustment handle 133 is rotated, the lowering plate 135 and the lowering restriction indicator 135b are rotated by the chain 137. Then, the lowering limit switch 135c also rotates. At this time, the indicator 131 indicates “0”, and the cam 112a is also in the direction of “0”.

  Next, when the selection switch 140 is rotated from OFF to descending ON, the braking state of the electromagnetic brake 120 is released, and the drum 101 and the rotating shaft 109 are rotated by the weight of the weight 31 connected to the tip of the fishing line 30. Then, as the drum 101 rotates, the fishing line 30 wound around the drum 101 is unwound (unwound). In this state, the electromagnetic clutch 104 maintains the separated state, and the rotating shaft 109 is separated from the motor 102 and the speed reducer 103, so that the rotating shaft 109 can freely rotate.

  The rotation of the rotating shaft 109 due to the lowering of the fishing line 30 is transmitted to the input shaft 111 via the chain 108, and is largely decelerated by the worm speed reducer 110 and then transmitted to the output shaft 112. When the output shaft 112 rotates, the indicator 131 also rotates and gradually rotates from “0” toward “70”.

  When the indicator 131 indicates “70”, the protrusion of the cam 112 b that rotates with the output shaft 112 activates the lowering limit switch 135 c installed on the lowering plate 135. When the lowering limit switch 135c is operated, the electromagnetic brake 120 installed in the worm speed reducer 110 is operated to brake the rotation of the input shaft 111 and the rotating shaft 109. Therefore, the rotation of the drum 101 is quickly stopped, and the fishing line 30 cannot be further loosened, that is, the descent is stopped.

  While the fishing line 30 is descending into the seawater due to the weight of the weight 31, if the upper ball 33b hits the small ring 13, it will not descend further. This state is the state shown in FIG.

  In this way, when the fish 30 and the fishhook 32 are lowered in the seawater and the fish catches the fishhook 32 in the process of eating the bait attached to the fishhook 32, the number of fish caught on the fishhook 32 increases. Accordingly, the degree of curvature of the fishing rod 11 increases, and it is possible to estimate how much fish is caught by experience. For example, when it can be estimated that about 5 fish are caught on the fishing line 30, the lift adjustment handle 132 of the fishing machine 100 is rotated, and the lift limit indicator 134 b interlocked with the lift plate 134 is set to “0”. The fishing line 30 is pulled up from the seawater while the selector switch 140 is positioned to be turned on, the motor 102 is rotated, and the electromagnetic clutch 104 is operated to rotate the rotating shaft 109 in the opposite direction.

  In this state, if the indicator 131 of the water depth plate 130 gradually rotates counterclockwise toward “0” and reaches the position “0”, the cam rotates together with the output shaft 112 of the worm speed reducer 110. The operation of the motor 102 is stopped by operating the ascent restriction switch 134c provided on the ascending plate 134 by the protruding portion 112a, the electromagnetic clutch 104 is separated, and the electromagnetic brake 120 is activated to operate the drum 101 and the rotating shaft 109. Brakes the rotation of

  FIG. 2 shows a state in which the fishing line 30 is raised. In this state, the fish caught by the fishhook is removed and arranged while pulling up the fishing line 30 where the fish is caught by hand.

  While the fishing line 30 is raised or lowered by the motor 102, the ascending lamp 143 or the descending lamp 144 of the fishing machine 100 is lit.

  Then, when the fishing line 30 has been raised or lowered by the adjustment amount by the raising adjustment handle 132 or the lowering adjustment handle 133 and then has not risen or lowered to a desired extent by the naked eye, the raising button 141 or the lowering button 142 is set. While pushing, the fishing line 30 is raised or lowered.

  By observing the curvature of the fishing rod 11, the fishing apparatus according to the embodiment of the present invention can estimate the number of fish caught on the fishing line 30 relatively accurately, and the desired number of fish is applied. When the fishing line 30 is pulled up, the operation efficiency can be greatly improved.

  Since the fishing machine 100 used in the fishing device according to the embodiment of the present invention can automatically adjust the lowering and raising of the fishing line 30, the raising or lowering operation of the fishing line 30 is very easy. And can be implemented quickly.

  In the fishing machine 100 of the present embodiment, when the fishing line 30 is lowered, the fishing line 30 wound around the drum 101 descends into the sea while gradually unwinding by the weight of the weight 31, so that the fishing line 30 is not tangled. In addition, the bait hung on the hook 32 does not leave.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.

  The present invention observes the degree of curvature of the fishing rod, estimates the number of fish such as sword fish hung on the fishhook, and when it is judged that more fish than the target number of sword fish or the like is caught, pulls the fishing line, Furthermore, by automatically controlling the rise or fall of the fishing line according to the water depth, the present invention can be applied to a fishing device that can not only greatly improve the operation efficiency but also can be operated very simply.
