Description

Technical Field

[0001] The invention belongs to the technical field of marine fisheries, and in particular relates to a device for quickly cutting and arranging hairtail longline catches. Background Art

[0002] Hairtail is an important economic species for fishing in the East China Sea, with an annual output of about 900,000 tons, and has extremely high nutritional value. The main methods of catching hairtail are trawling, strewing and longline fishing. Compared with other fishing gear, longline fishing is recognized as a method of operation with good selectivity, ecological and environmental friendliness. As a typical passive fishing gear, hairtail longline fishing mainly uses the feeding habits of hairtail to induce it to swallow and bite the hook to achieve the purpose of capture. Due to the ferocious feeding habits of hairtail, the hook and bait are often swallowed by it. Fishermen usually install blades on the catch box to cut the branch line directly so that the catch falls directly into the catch box. The traditional cutting method is basically manual cutting, which is time-consuming and labor-intensive.

[0003] Application No. TW093217202 discloses a longline fishing dry rope gathering device, which at least includes a fixed bracket, a rope gathering roller, a rope guide part, a power unit, and a linkage unit. The rope gathering roller is mainly rotated by the power unit, and the rope gathering roller can synchronously drive the rope guide part to move through the linkage unit, so that the rope guide unit of the rope guide part can make left and right reciprocating motions, and the dry rope can be automatically wound and collected by the rope gathering roller in an orderly manner through the guidance of the rope guide unit of the rope guide part, thereby reducing the work of retracting and sorting the longline fishing dry rope, and can improve the convenience of putting the dry rope into the sea. The patent still has room for improvement.

[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art.

The cutting tool has a horizontal plate, an inclined plate having an angle with the horizontal plate is fixedly provided at the bottom of the horizontal plate, the inclined plate is parallel to the bottom edge of the first plate, and a triangular prism that tapers toward the cutting base is fixedly provided at the top of the horizontal plate. A third rod having the same structure as the second rod is provided on the upper part of the cutting tool, and the third rod is located on one side of the cutting base. A fourth rod having the same structure as the second rod is provided on the side of the third rod away from the cutting base, and the fourth rod is provided on the upper part of the cutting tool. A second plate is provided on the opposite side of the first plate, a through hole corresponding to the rod structure on the first plate is provided on the second plate, and the two plates are fixed by bolts through the threaded holes on each rod. A distance is provided between the cutting base and the second plate. One end of the main line is placed on a support tube, which is fixedly mounted on a support rod. The other end of the main line is wound around a fish rope collection tube, which is a cylinder that tapers from one end to the other end, and a circular plate having a diameter larger than the minimum diameter of the cylinder is fixedly disposed at one end of the cylinder with a smaller diameter.

[0008] When collecting fishing gear on the water, first pull the main line toward the boat through the support tube. The support tube can be fixedly installed on the edge of the hull or outside the edge of the hull. The support tube is set to have a middle diameter smaller than the diameter at both ends so that the main line will not easily fall off the support tube. The other end of the main line is wound around the fish rope collection tube through the fishing line bayonet. In this way, the main line and the branch line between the support tube and the fish rope collection tube are suspended. The fish rope collection tube is fixedly installed on the boat. A motor is provided at the bottom of the fish rope collection tube to control the rotation of the fish rope collection tube. The cutting tool and the cutting tool used in conjunction with the cutting tool are The cutting device is arranged between the fish rope collecting cylinder and the supporting cylinder. The cooperation between the fish rope collecting cylinder and the supporting cylinder can suspend the main line, so that the hairtails bitten by the hook on the branch line can move freely downward, and the branch lines are prevented from being entangled with each other or the hairtails colliding with the edge of the hull. The main line passes over the cutting tool, and the branch line enters from the gap between the cutting base and the second plate body. The first rod body, the second rod body, the third rod body and the fourth rod body are rod bodies with the same structure. The fish rope collecting cylinder is arranged on the side biased to the first plate body, the main line is biased to the side of the first plate body, and the branch line and the hairtails thereon are cut after passing through the tool in order.

[0009] The invention is further described as follows: first, after the main line is wound around the fishing line bayonet through the support tube, the motor controls the fish rope collecting tube to rotate, and the branch line and the hairtail on it are orderly pulled to the gap between the cutting base and the second plate body, and then the branch line is guided by the inclined part of the cutting base, and because the fish rope collecting tube is arranged on the side of the first plate body, the line body pulled to the cutting base is tightly attached to the first plate body, and finally the branch line is located between the vertical angle between the inner side wall of the cutting tool and the first plate body and the third rod body, and then the hairtail is pulled to the top of the first rod body by the branch line, and after the hairtail passes through the first rod body, due to the factors of its own length and gravity, the tail of the hairtail will fall, thereby pressing the bottom bending part of the cutting tool, that is, the inclined plate, causing the cutting tool to rotate around the second rod body, and the tip part of the triangular prism at the top of the cutting tool cuts off the branch line between the third rod body and the cutting base, and the hairtail falls into the catch box. Afterwards, the tool is separated from the cutting base, and the next branch line enters, and the cutting process is repeated. After the branch line is cut, it will be pulled by the main line and wound around the fish rope collection tube to play a sorting role. In addition, when the branch line is empty, the branch line without hook will be directly pulled to the fish rope collection tube for winding and sorting due to the light weight of its hook when it falls from the first rod body, so as to avoid the branch line with empty hook from being cut and reduce the workload of re-hanging the fish hook later. In addition, by counting the number of fish hooks on the fish rope collection tube, the number of hairtail caught can be quickly calculated, which is convenient for calculating the hairtail catch rate in the relative ocean area.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The coordination of the fish rope collection tube and the support tube can suspend the main line, so that the hairtails bitten by the hook on the branch line can move freely downward, avoiding the entanglement of the branch lines or the collision of the hairtails with the edge of the hull. The branch line with empty hooks will be directly pulled to the fish rope collection tube for winding and sorting, so as to avoid the branch line with empty hooks from being cut, and also reduce the workload of re-hanging the fish hooks later. The cutting position is close to the fish hook, which increases the reuse rate of the branch line. And by counting the number of fish hooks on the fish rope collection tube, the number of hairtails caught can be quickly calculated, which is convenient for calculating the hairtail catch rate in the relative ocean area.

[0016] Embodiment 1 See attached Figure 1-Figure 4 As shown, a device for quickly cutting and sorting the catch of hairtail longline fishing comprises a main line 10 and branch lines 101 arranged on the main line 10 at intervals, and a cutting tool 202 arranged under the main line 10, wherein the cutting tool 202 is movably arranged on a first plate body 201, a cutting base 203 is provided on one side of the first plate body 201, the cutting base 203 is a block whose thickness gradually increases inwardly from an edge of one side of the first plate body 201, and the side surface of the block facing one end of the cutting tool 202 is perpendicular to the first plate body 201.

[0017] A first rod 204 is provided on the first plate 201. The first rod 204 is fixedly provided at a distance below the cutting base 203. A through hole is provided at one end of the first rod 204 and a thread is provided inside the through hole. A second rod 205 is provided on the first plate 201. The cutting tool 202 is tilted and movably provided on the second rod 205. A through hole is provided at one end of the second rod 205 and a thread is provided inside the through hole. The cutting tool 202 has a horizontal plate. An inclined plate having an angle with the horizontal plate is fixedly provided at one end of the horizontal plate. The inclined plate is parallel to the bottom edge of the first plate 201. A triangular prism that tapers toward the cutting base 203 is fixedly provided on the top of the horizontal plate. A third rod 206 having the same structure as the second rod 205 is provided on the upper part of the cutting tool 202. The third rod 206 is located on one side of the cutting base 203. A fourth rod 207 having the same structure as the second rod 205 is provided on the side of the third rod 206 away from the cutting base 203, and the fourth rod 207 is provided on the upper part of the cutting tool 202. A second plate 208 is provided on the opposite side of the first plate 201, and a through hole corresponding to the rod structure on the first plate 201 is provided on the second plate 208, and the two plates are fixed by bolts through the threaded holes on each rod. A distance is provided between the cutting base 203 and the second plate 208. One end of the trunk line 10 is placed on the support cylinder 102, and the support cylinder 102 is fixedly mounted on the support rod 103. The other end of the trunk line 10 is wound around the fish rope collection cylinder 30, which is a cylinder that tapers from one end to the other end, and a circular plate having a diameter larger than the minimum diameter of the cylinder is fixedly provided at the end of the cylinder with a smaller diameter.

[0018] When collecting fishing gear on the water, first pull the main line 10 toward the boat through the support tube 102. The support tube 102 can be fixedly installed on the edge of the hull or outside the edge of the hull. The support tube 102 is set so that the middle diameter is smaller than the diameter at both ends so that the main line 10 will not easily fall off the support tube 102. The other end of the main line 10 is wound around the fish rope collection tube 30 through the fishing line bayonet 302. In this way, the main line 10 and the branch line 101 between the support tube 102 and the fish rope collection tube 30 are suspended. The fish rope collection tube 30 is fixedly installed on the boat. A motor is provided at the bottom of the fish rope collection tube 30 to control the rotation of the fish rope collection tube 30. The cutting tool 202 and The cutting device used in conjunction with the cutting tool 202 is arranged between the fish rope collecting tube 30 and the supporting tube 102. The cooperation between the fish rope collecting tube 30 and the supporting tube 102 can suspend the main line 10, so that the hairtails bitten by the hook on the branch line 101 can move freely downward, and the branch lines 101 are prevented from being entangled with each other or the hairtails from colliding with the edge of the hull. The main line 10 passes over the cutting tool 202, and the branch line 101 enters from the gap between the cutting base 203 and the second plate body 208. The fish rope collecting tube 30 is arranged on the side biased to the first plate body 201, and the main line 10 is biased to the side of the first plate body 201, and the branch line 101 and the hairtails thereon are cut after passing through the tool in an orderly manner.

[0019] Specifically, first, after the main line 10 is wound around the fishing line bayonet 302 through the support tube 102, the motor controls the fishing line collecting tube 30 to rotate, and the branch line 101 and the hairtail on it are pulled to the gap between the cutting base 203 and the second plate 208 in an orderly manner. Figure 2 , and then the branch line 101 is guided by the inclined part of the cutting base 203, and because the fish rope collecting tube 30 is arranged on the side biased to the first plate body 201, the line body pulled toward the cutting base 203 is tightly attached to the first plate body 201, and finally the branch line 101 is located between the vertical angle between the inner side wall of the cutting tool 202 and the first plate body 201 and the third rod body 206, and then the hairtail is pulled toward the top of the first rod body 204 by the branch line 101. After the hairtail passes through the first rod body 204, the tail of the hairtail will fall due to the length of the hairtail itself and the gravity, thereby pressing the bent part at the bottom of the cutting tool 202, causing the cutting tool 202 to rotate around the second rod body 205, and the tip part of the triangular prism at the top of the cutting tool 202 cuts off the branch line 101 between the third rod body 206 and the cutting base 203, and the hairtail falls into the catch box 301. Furthermore, since the branch line 101 is cut only when it pulls the hairtail to the cutter, the cutting position is closer to the fishhook, thereby increasing the reuse rate of the branch line 101.

[0020] Afterwards, the cutter is separated from the cutting base 203, and the next branch line 101 enters and repeats the cutting process. The branch line 101 after cutting will be wound on the fish rope collection tube 30 through the traction of the main line 10 to play a finishing role. And when the branch line 101 is empty, the branch line 101 that is not hooked is falling from the first rod body 204, because its fish hook is lighter, it is not enough to press the bottom bending part of the cutting tool 202, so the branch line 101 of the empty hook will be directly pulled to the fish rope collection tube 30 to wind and arrange, to achieve the effect of avoiding the branch line 101 of the empty hook from being cut, and also reduce the workload of re-hanging the fish hook in the later stage. And by counting the number of fish hooks on the fish rope collection tube 30, the number of hairtails caught can be quickly calculated, which is convenient for calculating the hairtail capture rate in the relative ocean area. The personnel can also optimize the arrangement of the fish hooks according to the hairtail biting situation, such as the distance between the fish hooks.
