Description

Technical Field

[0001] The present invention relates to the technical field of deep - sea squid jigging, and particularly to an improved squid jig suitable for low - density resource conditions. Background Art

[0002] The deep - sea squid jigging fishing ground in the northwest Pacific Ocean is a very important fishing ground for China's deep - sea squid jigging industry. Due to the large area of the North Pacific fishing ground and it being a deep - water fishing ground, the area suitable for squid habitation is very broad. Therefore, the fish school clustering density in this fishing ground is much lower than that of other squid fishing grounds. Also, precisely because of the low fish school density, squids are obviously fearful when preying and are very picky about the number, color, jitter frequency, etc. of the fishing hooks, which leads to a relatively low hook - up rate of squids in the North Pacific fishing ground.

[0003] Generally, the hook - up rate of the jig is much lower than that of manual hand - jigging. Therefore, current North Pacific fishing boats all adopt a pure manual fishing method, which is the main reason for the relatively low average daily output per boat in this fishing ground. Compared with the two major squid fishing grounds in the southeast Pacific Ocean and the southwest Atlantic Ocean, the annual output per boat (CPUE value) in the North Pacific fishing ground is relatively low, but the fluctuation range of the annual occurrence of squid resources is relatively small. It belongs to a low - density and resource - stable fishing ground.

[0004] Currently, most of the squid jigs introduced and used in China are the automatic jigs of the MY series of Hamade Electric Machinery Works in Japan and the SE series of Sanme Manufacturing Co., Ltd. in Japan. Both of these two types of jigs achieve jitter by using the unequal - pitch feature of a hexagonal drum. Although the intensity of their jitter can be adjusted in different grades, there is still a large gap in the softness of jitter compared with hand - jigging, and the rising speed of the fishing line cannot be adjusted according to the magnitude of the pulling force generated by the sea wave fluctuations on the fishing line. Therefore, these two types of jigs are more suitable for fishing grounds with relatively high squid clustering density and relatively high wrist - breaking strength such as the southwest Atlantic Ocean. In the North Pacific fishing ground, it is necessary to develop and improve the squid jig in view of the specific problems such as the fear of the squid when pouncing on the hook at low density in the North Pacific, the low wrist - breaking strength of the squid, and the harsh sea conditions in the North Pacific. Summary of the Invention

[0005] The present invention provides an improved squid jig suitable for low - density resource conditions, which adopts a single - drum single - line device and a fishing - hook method of increasing the spacing between fishing hooks, reduces the mutual influence between fishing hooks of the two lines, and improves the probability of catching fish during the rising process of the fishing hooks.

[0006] The present application is achieved through the following technical solutions:

[0007] An improved squid jigging machine suitable for low-density resource states, including a machine body, the machine body includes a motor, the motor is connected to a drum, a fishing line is arranged on the drum, fishing hooks are arranged on the fishing line, and the machine body controls the rotation of the drum to control the pulling speed, lowering speed and jitter frequency of the fishing line.

[0008] Preferably, the distance between adjacent fishing hooks on the fishing line is about 1.5 meters.

[0009] Preferably, the rising speed of the fishing line is 45 r / min.

[0010] Preferably, the drum is a six-cylinder drum.

[0011] Preferably, the motor is connected to a sensor to control the rising speed of the fishing line in real time, and the sensor transmits the rising speed of the fishing line to the main controller for comprehensive analysis and judgment.

[0012] Design principle of the present invention:

[0013] (1) In the jitter mode, technologies such as a circular drum, computer memory of artificial jitter information, and motor frequency conversion control are adopted to copy the artificial hand-jigging jitter into the jigging machine jitter mode.

[0014] (2) In the process control of machine fishing, the tension sensing technology is used to make the jigging machine stay in the state of jittering in place to lure fish until the first fish is hooked, and then it rises slowly in a jittering manner to extend the effective fish luring time. During the rising process of the fishing hook, when the hull rises or falls with the waves, the rising speed of the jigging machine is synchronously reduced or increased to reduce the rate of squid breaking its wrist and getting off the hook.

[0015] (3) To solve the problem of the fear of the squid being hooked caused by the fishing hook and fishing line, it is solved by optimizing the fishing hook setting: one is to adopt the fishing hook method of a single drum and single line device to reduce the mutual influence of the fishing hooks between the two lines on the squid being hooked, and at the same time reduce the probability of the two lines winding around each other; the other is to increase the distance between the fishing hooks, increasing the hook spacing from the traditional 0.8 m to 1.5 m, which can reduce the influence of the upper and lower fishing hooks on the squid being hooked.

[0016] Beneficial effects: The squid jigging machine of the present invention reduces the mutual influence between the fishing hooks between the two lines, and at the same time reduces the probability of the fishing lines winding around each other. It greatly reduces the influence of the next fishing hook on the squid around the previous fishing hook when the squid is hooked, reduces the fear of the squid being hooked, the jitter mode of the present invention is close to artificial jitter, and increases the effective jitter and fish luring time. The present invention makes the jigging machine stay in the state of jittering in place to lure fish until the first fish is caught and then rises slowly in a jittering manner, improving the squid hooking rate of the squid jigging machine and the fish catching probability during the rising process of the fishing hook.

[0019] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings: These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0020] As Figure 2 shown, an improved squid fishing machine applicable to low-density resource states includes a machine body. The machine body includes an electric motor, which is connected to a drum. The drum is provided with a fishing line, and the fishing line is provided with fishing hooks. The machine body controls the rotation of the drum to control the pulling speed, lowering speed, and jitter frequency of the fishing line. The distance between adjacent fishing hooks on the fishing line is about 1.5 meters. The rising speed of the fishing line is 45 r / min. The drum is a six-cylinder drum. The electric motor is connected to a sensor to control the rising speed of the fishing line in real time, and the sensor transmits the rising speed of the fishing line to the main controller for comprehensive analysis and judgment.

[0021] (1) In the jitter mode, technologies such as a circular drum, computer memory of artificial jitter information, and motor frequency conversion control are adopted to copy the artificial hand-fishing jitter mode as the fishing machine jitter mode.

[0022] (2) In the control of the machine fishing process, a tension sensing technology is used to keep the fishing machine in a state of jittering in place to lure fish until the first fish is hooked, and then it rises slowly in a jittering manner to extend the effective fish luring time. During the rising process of the fishing hook, when the hull rises or falls with the waves, the rising speed of the fishing machine is synchronously reduced or increased to reduce the rate of squid breaking its wrist and getting off the hook.

[0023] (3) To solve the problem of the fear of hooking caused by the fishing hook and fishing line to squid, it is solved by optimizing the fishing hook setting: one is to adopt a single-drum single-line device for fishing hook setting to reduce the mutual influence of fishing hooks between the two lines on squid hooking and at the same time reduce the probability of the two lines winding around each other; the other is to increase the distance between fishing hooks, increasing the hook distance from the traditional 0.8 m to 1.5 m, which can reduce the influence of the upper and lower fishing hooks on squid hooking ( Figure 1 is a schematic diagram of the fishing line layout structure of the fishing machine in the prior art).

[0024] Through tests by the applicant, the results show that when the squid aggregation density is low, the output of the fishing machine is about twice that of the traditional method before improvement (double lines, 30 hooks per line with a hook spacing of 0.8 m and a line rising speed of 55 r / min); when the squid density is high, the output increase is not obvious and instead shows a decreasing trend. The test data shows that when the daily output per single ship is below 3 t, the output of 3 fishing machines is approximately equivalent to that of 1 fisherman; when the daily output per single ship is around 4 t, the output of 2 fishing machines is approximately equivalent to that of 1 fisherman; when the daily output per single ship is 5 t, the output of 1 fishing machine is approximately equivalent to that of 1 fisherman; when the daily output per single ship is above 6 t, the output of 1 fishing machine is approximately equivalent to that of 1 fisherman.

[0025] The results of the fishing machine improvement test show that by improving the line set and hook spacing of the fishing machine and reducing the rising rotation speed, the fear of squid attacking the hooks can be effectively reduced, the hook-up rate can be increased, and the rate of wrist-breaking and hook detachment can be reduced; when the daily output per single ship reaches more than 5 t, the fish-catching rate of the improved fishing machine is not much different from that before improvement, and as the squid density further increases, the output of the improved fishing machine decreases compared with that before improvement. This shows that the fear of squid has basically disappeared at this time, and the improved fishing machine limits the fishing output due to a significant reduction in the number of hooks and a slower roller rotation speed. Therefore, when the fishery resource density is high, the line set and the number of hooks of the fishing machine should be increased as appropriate, and the roller rotation speed should be appropriately increased.
