Description

Technical Field

[0001] The present invention relates to the technical field of net collecting, and more particularly to an automatic fishing net collecting technology. Background Art

[0002] In the traditional mode, it takes a lot of manpower to operate the net collection in the fish pond, including pulling the net to drive the fish, collecting the net to catch the fish, carrying, etc., which is labor-intensive and inefficient. At the same time, the manual net collection process is cumbersome and time-consuming, especially in large fish ponds, it may take several days to complete the fishing and net collection work. With the rising labor costs in rural areas and the shortage of human resources, the traditional manual fishing method is becoming less and less economically competitive. The present invention proposes an automatic fishing and net collection device for fish ponds. The present invention adopts a motor to provide power drive, a shifting mechanism to change the direction of movement, and transmits power from different directions. The first and second level winches respectively perform the physical actions of collecting and pulling the net, and provide a precise path along the outer guide rail of the fish pond, so that the pull ropes, sliders or carriers on both sides of the fishing net can move smoothly along the predetermined trajectory, so that the entire process of fishing such as setting the net, collecting the net, and catching fish can be completed continuously and quickly and automatically. Summary of the invention

[0003] In order to solve the problems of time-consuming manual operation, high labor intensity and low efficiency in the traditional fishing operation mode in rural fish ponds, the present invention proposes an automatic fishing net collection device for fish ponds. The net collection device is composed of a motor, a shifting mechanism, an actuator and a guide mechanism. The guide mechanism sets a track along the periphery of the fish pond. The pull ropes on both sides of the fishing net are respectively fixed on the track sliders. The end of the track extends to the winch of the actuator. The first-level winch in the actuator drives the pull ropes at both ends of the fishing net to realize the action of closing the net and driving the fish, and the second-level winch drives the pull rope to realize the action of pulling the net and catching fish. When driven by the motor, the automatic device can continuously and quickly catch fish. Compared with traditional manual fishing, the efficiency, safety and economy are greatly improved.

[0004] In order to achieve the above technical objectives, the present invention is implemented through the following technical solutions:

[0005] An automatic fishing net collecting device for a fish pond, comprising:

[0006] The fishing net is made of nylon, polyethylene, polyester or other synthetic fiber materials, and has a flat mesh structure with a size equal to the width of a fish pond. There are net collecting ropes a at both ends of the top of the mesh for connecting to the hooks on the guide slider, and there are net pulling ropes at both ends of the bottom of the mesh for connecting to the pull rope buckles at both ends of the secondary winch. The bottom of the mesh is evenly connected to sinker parts to allow the lower part of the fishing net to sink into the water.

[0007] The guide mechanism adopts segmented linear and circular aluminum guide rails, which include segmented guide rails, sliders with seals, balls, retainers, and limit end blocks; the slider is provided with an inverted mounting hook, the end of the hook is fixedly mounted on the slider with a threaded connection, and the segmented guide rails are fixed with positioning pins and bolts;

[0008] The actuator adopts a winch device, which is divided into two-stage winches. The first-stage winch is arranged below the device, and the second-stage winch is arranged above the device. The outer diameter dimension D of the first-stage winch is larger than the dimension D′ of the second-stage winch, and the axial dimension L of the first-stage winch is smaller than the dimension L′ of the second-stage winch. Net-collecting ropes b are arranged at both ends of the first-stage winch, and the ends of the net-collecting ropes b are connected to the guide sliders. Rope buckles are arranged at both ends of the second-stage winch.

[0009] The shift mechanism uses a movable shift lever with two gears. The first gear is that the power is transmitted to the main shaft, driving the first-stage capstan to rotate; the second gear is that the power is switched to the secondary shaft, driving the second-stage capstan to rotate.

[0010] Specifically, the technical principle of the present invention for improving fishing efficiency is as follows: according to the width of the fish pond, the segmented guide rails are manually set up and connected on both sides of the fish pond in advance, the fishing net is arranged on one side of the fish pond, the net-collecting ropes a at both ends are respectively connected to the hooks of the guide slider, the net-pulling ropes at both ends are respectively connected to the buckles of the guide slider, and the primary winch is connected to the other end of the guide slider through the net-collecting rope b. When the motor is started, the shift lever is in the left position, and the primary winch is driven to rotate through the V-belt pulley deceleration. The winch pulls the net-collecting rope b to drive the slider to move along the guide rail, and the directional movement of the slider drives the two ends of the fishing net to move to the limit end block at the end of the guide rail at the same time, so as to realize the net-collecting action. After the net-collecting action is completed, the fishing net drives the fish to the other side of the fish pond, the net-pulling rope is removed from the slider buckle, and is switched to the secondary winch buckle position, the shift mechanism lever is operated to the right position, the secondary winch is rotated to drive the net-pulling rope, and the net-pulling action is realized. During this process, the speed of the net is adjusted according to the motor speed and the speed reducer, and the pulling force of the net is determined by the motor power according to the approximate weight of the fish in the pond. The motor first drives the first winch to realize the net-closing action, and then drives the second winch to realize the net-pulling action, thereby realizing the automated fishing process.

[0011] Optionally, the fishing net is made of nylon, polyethylene, polyester or other synthetic fiber materials. Optionally, the fishing net is made of natural cotton or linen.

[0012] Optionally, the guide mechanism is composed of a segmented linear guide rail. Optionally, the guide mechanism is composed of a segmented curved guide rail or a circular guide rail.

[0013] Optionally, the actuator is composed of a winch device. Optionally, the actuator is composed of a cable drum and a chain drum.

[0014] Finally, because the present invention uses a guide rail mechanism to fix the two ends of the fishing net, and the guide rail is arranged along the periphery of the fish pond, the fishing net folding process has good directionality and the folding area is maximized. At the same time, the winch is driven by a motor during the net pulling process, which saves a lot of manpower. Therefore, it solves the problems of high labor intensity and low efficiency in traditional fish pond fishing, such as folding the net to drive fish, pulling the net to catch fish, and carrying, so that the present invention has higher fishing efficiency.

DETAILED DESCRIPTION

[0022] Example 1

[0023] Figure 1A schematic diagram of the structure of an automated fishing net collection device provided for this implementation case. The automated fishing net collection device consists of a fishing net 100, a guide rail slider 200, a segmented guide rail 300, a winch 400, a motor 500, a shift mechanism 600, and a base 700. The fishing net 100 is used to enclose a school of fish and then collect the net to capture it. The guide rail slider 200 and the segmented guide rail 300 are used to support the fishing net and provide an accurate straight or curved motion path to ensure smooth and accurate motion. The winch 400, the motor 500, and the shift mechanism 600 are used to wind the fishing net rope to achieve mechanized collection and release of large-area fishing nets.

[0024] Net-collecting ropes a120 are provided on both sides of the top of the fishing net 100, which are respectively fixedly connected to the net-collecting hooks 210 of the guide rail slider, and a certain tension is maintained during the process to ensure that the top of the fishing net remains in an open state. Net-pulling ropes 130 are provided on both sides of the bottom of the fishing net 100, which are respectively fixedly connected to the net-pulling hooks 260 of the guide rail slider, and a certain tension is maintained during the process to ensure that the bottom of the fishing net remains in an open state. Sinkers 110 are evenly distributed at the bottom of the lower edge of the fishing net, and their weight helps the fishing net sink to the predetermined water layer, ensuring that the fishing net can stay in the best position for fishing. The net-collecting rope a120, the net-pulling rope 130, and the sinkers 110 maintain a certain tension in all directions, helping the fishing net to maintain its shape outside the fish pond and improve fishing efficiency.

[0025] The segmented guide rail 300 is distributed along the periphery of the fish pond and is composed of a plurality of short guide rail modules (linear guide rail 320, circular guide rail 330) that are freely combined. The length of each short guide rail is 2 meters. According to the actual size of the fish pond, guide rail modules of different lengths and types can be flexibly combined. The guide rail bracket 340 is manually fixed to the ground in advance with bolts and gaskets, and the short guide rails are fixed with bolts and gaskets.

[0026] The guide rail slider 200 is composed of a slider platform 220, a slider fixing plate 230, a slider bracket 240, a net collection hook 210, a net pulling hook 260, and a roller 250. The slider fixing plate 230 is provided with an annular buckle for connecting the net collection rope 310b. The entire guide rail slider 200 is used in conjunction with the segmented guide rail 300, and the net pulling hook 260 and the net collection hook 210 drive the fishing net 100 to move smoothly and accurately in a straight line or curve on the guide rail 300, and finally realize the collection of the fishing net from one side of the fish pond to the primary winch 410.

[0027] The motor 500 transmits power to the shift mechanism 600 through the pulley 510. The shift mechanism can be operated to select different transmission ratios, thereby changing the speed and torque of the winch. The low speed gear is initially selected to provide greater torque. The power will be transmitted to the drive shaft of the primary winch 410 through the gearbox. The drive shaft of the winch is connected to the drum of the winch. The drum is wound with a net-collecting rope b. When the power is transmitted to the primary winch 410, the drum starts to rotate, and the net-collecting rope b will be wound to perform the net-collecting operation and collect the fishing net from the water. After the net-collecting action is completed, the hook of the net-drawing rope 130 is removed from the net-drawing hook 260, and then hung on the buckle of the secondary winch 420. Then, the gear lever of the shift mechanism 600 is pulled to switch the power direction, and the power is transmitted to the drive shaft of the secondary winch 420, driving the net-drawing rope 130 to be wound, and realizing the net-drawing operation of the fishing net 100.

[0028] Finally, because the present invention adopts automated control, the whole process of automatic net setting, all-round fishing and net collection in the fish pond environment is automated, which reduces manual intervention and saves a lot of time. Therefore, it solves the problem that the traditional mode of collecting nets in the fish pond requires a lot of manpower and is time-consuming, thereby making the present invention have higher fishing efficiency.
