Description

Technical Field

[0001] This invention relates to the field of freshwater aquaculture technology, and particularly to a freshwater aquaculture fishing device. Background Technology

[0002] Freshwater aquaculture refers to a production method that utilizes freshwater bodies such as rivers, lakes, reservoirs, and ponds to raise aquatic organisms. Among these, pond aquaculture is the most common method. It involves constructing artificial ponds, controlling water quality, and feeding conditions to conduct high-density farming. The pond area can be determined based on actual conditions, generally ranging from a few acres to tens of acres. Common fish species such as grass carp, common carp, crucian carp, silver carp, and bighead carp are typically raised in ponds, characterized by rapid growth, strong adaptability, and delicious meat.

[0003] Chinese patent document CN 204272941 U discloses a freshwater aquaculture fishing device, including an aquaculture pond body 1 and a smart mobile terminal 2. A platform 3 is located at the center of the aquaculture pond body 1, and a fishing unit is located on the upper end of the platform 3. Multiple detection units are located on the side surface of the platform 3. The detection units and the fishing unit are wirelessly connected to the smart mobile terminal 2 and operate under its control. The fishing unit consists of a positioning motor 4 fixedly installed at the top of the platform 3, a spray gun 5 fixedly installed at the rotating end of the positioning motor 4, a collecting motor 6 located on the side surface of the positioning motor 4, a fishing net 7 that can be stored inside the spray gun 5, a bait device 8 fixedly installed at the center of the fishing net 7, multiple counterweights 9 fixedly installed at the edge of the fishing net 7, and a steel wire rope 10 located on the edge of the fishing net 7 with both ends extending out of the net 7 and fixedly connected to the rotating end of the collecting motor 6. This solution has a simple structure and can perform net fishing electrically, saving labor and improving fishing efficiency.

[0004] For example, Chinese patent document CN 213663193 U discloses a freshwater aquaculture fishing device, including a base plate, a support plate, a fishing box, and a box body. The support plate is fixedly connected to the base plate. A stirring mechanism is provided inside the box body. A first water pump is fixedly connected to the support plate. A first pipe connects the first water pump to the box body. A first nozzle is fixedly connected to the bottom of the support plate. A second pipe connects the first water pump to the first nozzle. A slider is slidably connected inside the support plate. This design is simple in structure and easy to operate. The fish feed is evenly stirred and sprayed around the fishing box by the cooperation of the first motor and the first water pump to better attract fish into the net. The position of the fishing box is adjusted by the cooperation of the cylinder and the slider, greatly improving its practicality.

[0005] For example, Chinese patent document CN 214629228 U discloses a freshwater aquaculture fishing device, including a floating frame. The bottom of the floating frame has a rectangular frame, and the front, rear, and bottom of the rectangular frame are all equipped with fixed net plates. The middle of the fixed net plate has a fish inlet. The left side of the rectangular frame has a fish catching mechanism, which includes a fixed frame. The bottom of the inner wall of the fixed frame is hinged to a movable plate. The right side of the rectangular frame has a rectangular fixed plate, and the middle of the side of the rectangular fixed plate has an installation groove with a screening net plate inside. This design allows freshwater fish to enter the rectangular frame through the three fish inlets, and prevents qualified freshwater fish from escaping. Under the action of the screening net plate, unqualified freshwater fish can swim away from the mesh of the screening net plate, thereby reducing the chance of catching small fish and reducing unnecessary losses.

[0006] However, the above scheme is still based on the idea of ​​cage fishing, which has low fishing efficiency and poor automation. At the same time, it cannot achieve large-area coverage for large ponds, and the cage placement is relatively fixed, making it difficult to catch the fish waiting to be harvested in the pond at one time. Summary of the Invention

[0007] The purpose of this invention is to provide a freshwater aquaculture fishing device that aims to solve the problem of inefficient fish capture in ponds during large-scale aquaculture.

[0008] The present invention is implemented as follows: a freshwater aquaculture fishing device includes support seats installed on both sides of a pond embankment. A pair of support seats on the left and right sides of the embankment are grouped together, and a pulley is bolted to each of them. The pulleys on a group of support seats are connected by a rubber belt for transmission. The pulleys are driven by a trawl drive mechanism. The inner side of the rubber belt is machined with a locking block, and the pulley is machined with a locking groove. The locking block can be detachably locked into the locking groove. Several mounting rings are machined on the outer surface of the rubber belt, and the trawl mechanism is suspended between the two parallel groups of support seats.

[0009] In a preferred embodiment of the present invention, several sets of support seats are provided on both sides of the pond embankment. Two sets of support seats with different spacing are selected to facilitate the hanging of trawl nets of different sizes. At the same time, the rubber belt and the pulley are detachable, making it easier to replace the rubber belt in different installation positions.

[0010] In a preferred embodiment of the present invention, the mounting rings are equidistantly distributed on the outer surface of the rubber belt, which facilitates the application to different sizes of trawl nets when suspending them. At the same time, the equidistant distribution facilitates the balance of the weight distribution of the trawl nets on the rubber belt when suspending them, thus ensuring that the service life of the rubber belt is extended.

[0011] In a preferred embodiment of the present invention, the trawl mechanism includes a trawl hanging ring, which is detachably mounted on the mounting ring. A trawl net is provided below the trawl hanging ring, a sinker is provided at the bottom of the trawl net, and a net-collecting mechanism is provided at the left end opening of the trawl net. When fishing, the trawl mechanism mounted on the mounting ring is simply used to transport the trawl mechanism into the pond, thereby realizing automated trawl fishing technology in the pond. At the same time, by adjusting the length of the trawl hanging ring, the trawl fishing technology at different depths in the pond can be controlled, allowing for targeted capture of fish at different depths in the pond, thus improving the economic benefits for fish farmers.

[0012] The net-hauling mechanism includes a rolled edge sewn to the left opening of the trawl net. A float is provided on the upper part of the rolled edge, and a sinker is provided on the lower part. When placed in the pond, the float floats upward and the sinker sinks downward, thus opening the rolled edge for fishing. Both the float and the sinker are connected to a pull rope, which passes through the net-hauling reel and extends to the shore. After the trawl net mechanism moves through the entire pond, the trawl fishing operation is completed. At this point, the net needs to be hauled in. The operator simply pulls the pull rope taut, which pulls the float and sinker close to the net-hauling reel, thus completing the hauling operation.

[0013] The hauling reel includes a reel body and mounting holes. The mounting holes are formed on the reel body. The diameter of the mounting holes is smaller than the diameter of the float and sinker but larger than the diameter of the pull rope. This way, when the pull rope is tightened, the float and sinker will be stuck on the reel body and cannot pass through the mounting holes, thus achieving the hauling of the trawl net.

[0014] In a preferred embodiment of the present invention, the trawl drive mechanism includes a pulley, the pulley being coaxially welded to the belt pulley, and the pulley being connected to the drive motor via a belt;

[0015] In a preferred embodiment of the present invention, the moving end of the trawl mechanism is provided with a net-collecting auxiliary mechanism to facilitate the net-collecting operation of the trawl mechanism. The net-collecting auxiliary mechanism includes a base, on which a drive rod is welded and fixed. The outer circumferential surface of the drive rod is machined with several teeth to facilitate locking onto the trawl net during assisted net collection and increase the friction force on the trawl net. The drive rod is welded and fixed to a driven wheel, which is connected to a driving wheel via a transmission belt. The driving wheel is welded and fixed to the output shaft of a transmission motor.

[0016] Compared with the prior art, the technical advantages of the injection teaching device provided in this invention are as follows:

[0017] 1. Select two sets of support seats with different spacing to facilitate the hanging of trawl nets of different sizes;

[0018] 2. The mounting rings are evenly distributed on the outer surface of the rubber belt, which makes it easy to accommodate different sizes of trawl nets when hanging them. At the same time, the evenly distributed distribution makes it easier to balance the weight distribution of the trawl nets on the rubber belt when hanging them, thus ensuring that the service life of the rubber belt is extended.

[0019] 3. When fishing, simply use the installation ring to transport the trawl net mechanism attached to the installation ring into the pond, and you can realize automated trawl fishing technology in the pond. At the same time, by adjusting the length of the trawl net hanging ring, you can also control the trawl fishing technology at different depths in the pond, and you can target fish at different depths in the pond to improve the economic benefits of fish farmers.

[0020] 4. When hauling in the net, the staff only needs to tighten the rope. After tightening, the float and sinker will be pulled to fit against the net hauling tray, thus completing the hauling operation.

[0021] 5. When hauling in the net, the trawl can be secured to the hauling assist mechanism, reducing the difficulty for operators in dragging the trawl and making it more labor-saving and efficient to lift the catch from the trawl. Attached Figure Description

[0040] Furthermore, such as Figure 8 and Figure 9 As shown, the mounting rings 5 ​​are evenly distributed on the outer surface of the rubber belt 4, which facilitates the application of different sizes of trawl nets when suspending them later. At the same time, the evenly distributed distribution helps to balance the weight distribution of the trawl nets on the rubber belt 4 when suspending them, thus ensuring that the service life of the rubber belt 4 is extended.

[0041] Example 4

[0042] like Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment of the present invention, a freshwater aquaculture fishing device includes support seats 1 installed on both sides of the embankment of a pond 2. A pair of support seats 1 on the left and right sides of the embankment are grouped together, and a pulley 3 is bolted to each of them. The pulleys 3 on a group of support seats 1 are connected by a rubber belt 4. The pulleys 3 are driven by a trawl drive mechanism 7. The inner side of the rubber belt 4 is machined with a locking block 41, and the pulley 3 is machined with a locking groove 31. The locking block 41 is detachably locked in the locking groove 31. Several mounting rings 5 ​​are machined on the outer surface of the rubber belt 4. The trawl mechanism 6 is suspended between two parallel groups of support seats 1. Several groups of support seats 1 are provided on both sides of the embankment of the pond 2. Two groups of support seats 1 with different spacing are selected to facilitate the suspension of trawls of different sizes. At the same time, the rubber belt 4 and the pulley 3 are detachably installed, making it easier to replace the rubber belt 4 in different installation positions.

[0043] The trawl mechanism 6 includes a trawl hanging ring 601, which is detachably mounted on the mounting ring 5. A trawl net 602 is provided below the trawl hanging ring 601, and a sinker 603 is provided at the bottom of the trawl net 602. A net-collecting mechanism 604 is provided at the left end opening of the trawl net 602. When fishing, the trawl mechanism 6 mounted on the mounting ring 5 is simply used to transport the trawl mechanism 6 into the pond 2, thereby realizing automated trawl fishing technology in the pond 2. At the same time, by adjusting the length of the trawl hanging ring 601, the trawl net 602 can be controlled to trawl at different depths in the pond 2, which can target fish at different depths in the pond 2 and improve the economic benefits for fish farmers.

[0044] Furthermore, such as Figure 5 As shown, the net-hauling mechanism 604 includes a rolled edge 605 sewn to the left opening of the trawl net 602. A float 606 is provided on the upper part of the rolled edge 605, and a sinker 607 is provided on the lower part of the rolled edge 605. When placed in the pond 2, the float 606 floats upward in the water, and the sinker 607 sinks downward, thus opening the rolled edge 605 for fishing. Both the float 606 and the sinker 607 are connected to a pull rope 608, which passes through the net-hauling reel 609 and extends to the shore. After the trawl net mechanism 6 has moved through the entire pond 2, the trawl fishing operation is completed. At this point, the net needs to be hauled in. The operator only needs to tighten the pull rope 608. After tightening, both the float 606 and the sinker 607 will be pulled to fit against the net-hauling reel 609, thus completing the hauling operation.

[0045] Among them, such as Figure 6As shown, the haul net 609 includes a haul net body 610 and a mounting hole 611. The mounting hole 611 is formed on the haul net body 610. The diameter of the mounting hole 611 is smaller than the diameter of the float 606 and the sinker 607 but larger than the diameter of the pull rope 608. In this way, when the pull rope 608 is tightened, the float 606 and the sinker 607 will be stuck on the haul net body 610 and will not be able to pass through the mounting hole 611, thus realizing the haul net haul-in.

[0046] Furthermore, such as Figure 8 and Figure 9 As shown, the mounting rings 5 ​​are evenly distributed on the outer surface of the rubber belt 4, which facilitates the application of different sizes of trawl nets when suspending them later. At the same time, the evenly distributed distribution helps to balance the weight distribution of the trawl nets on the rubber belt 4 when suspending them, thus ensuring that the service life of the rubber belt 4 is extended.

[0049] The trawl mechanism 6 includes a trawl hanging ring 601, which is detachably mounted on the mounting ring 5. A trawl net 602 is provided below the trawl hanging ring 601, and a sinker 603 is provided at the bottom of the trawl net 602. A net-collecting mechanism 604 is provided at the left end opening of the trawl net 602.

[0051] Among them, such as Figure 6 As shown, the haul net 609 includes a haul net body 610 and a mounting hole 611. The mounting hole 611 is formed on the haul net body 610. The diameter of the mounting hole 611 is smaller than the diameter of the float 606 and the sinker 607 but larger than the diameter of the pull rope 608. In this way, when the pull rope 608 is tightened, the float 606 and the sinker 607 will be stuck on the haul net body 610 and will not be able to pass through the mounting hole 611, thus realizing the haul net haul-in.

[0052] Furthermore, such as Figure 8 and Figure 9 As shown, the mounting rings 5 ​​are evenly distributed on the outer surface of the rubber belt 4, which makes it easy to accommodate different sizes of trawl nets when hanging them later. At the same time, the evenly distributed distribution makes it easier to balance the weight distribution of the trawl net on the rubber belt 4 when hanging the net, thus ensuring that the service life of the rubber belt 4 is extended.

[0053] Furthermore, such as Figure 2 As shown, the trawler drive mechanism 7 includes a pulley 71, which is coaxially welded to the pulley 3, and the pulley 71 is connected to the drive motor 73 via a belt 72.

[0057] Furthermore, such as Figure 5 As shown, the net-hauling mechanism 604 includes a rolled edge 605 sewn to the left opening of the trawl net 602. A float 606 is provided on the upper part of the rolled edge 605, and a sinker 607 is provided on the lower part of the rolled edge 605. When placed in the pond 2, the float 606 floats upward in the water, and the sinker 607 sinks downward, thus opening the rolled edge 605 for fishing.

[0061] Furthermore, such as Figure 3 and Figure 4 As shown, the moving end of the trawl mechanism 6 is provided with a net-collecting auxiliary mechanism 8, which facilitates the net-collecting operation of the trawl mechanism 6. The net-collecting auxiliary mechanism 8 includes a base 81, on which a drive rod 82 is welded and fixed. The outer circumferential surface of the drive rod 82 is machined with several teeth 83, which facilitates locking onto the trawl net during auxiliary net collection and increases the friction on the trawl net.
