Description
Technical Field
[0001] The utility model belongs to the technical field of automatic fishing devices, and in particular relates to an automatic device for improving the efficiency of pond fishing and fish grading and classification. Background Art
[0002] At present, the aquaculture industry has advanced technologies such as refrigeration, automatic oxygen supply, and water circulation filtration in the product transportation link, which ensures the survival rate of live fish and fresh fish in the transportation link. However, in the pond fishing link, fishing nets are basically used to let a large number of workers go to the pond to step on the nets, and then collect the nets to catch fish. The labor intensity is high, which seriously wastes manpower and cannot save the company's labor costs. If the pond area is large, the catch rate cannot be guaranteed. In the fish grading link, most of them still use the traditional method of manual fish sorting, that is, after the workers gather the farmed fish together with nets, they use experience to judge the fish species and the corresponding total amount, and then throw the fish into the area surrounded by different nets, resulting in high labor costs and causing hypoxia in the water body, which in turn causes fish deaths.
[0003] The existing patent CN209436061U discloses a fish grading net cage, which comprises a net cage body and a first net plate and a second net plate arranged in the net cage body. The net cage body is a rectangular box structure without an upper surface. In the prior art, a first net plate and a second net plate are arranged in the net cage body. The first net plate is provided with a large leakage hole, the second net plate is provided with a medium leakage hole, and the bottom surface of the net cage body is provided with a small leakage hole. The fish in the net cage body can be classified according to the leakage holes and fall into the corresponding intervals for automatic classification, thereby avoiding the tedious steps of manual classification and saving manpower. Although the fish can be preliminarily classified, the caught fish need to be transferred from top to bottom to the corresponding net plates for classification. However, a large number of large-sized fish on the top net plate will block the leakage holes, and small-sized fish are difficult to fall to the net plates of the next level, resulting in fish of different sizes still existing on the net plates of each level, so the grading effect is poor.
[0004] Based on this, it is necessary to design an automated device to improve the efficiency of pond fishing and fish grading and classification, so as to improve the fish grading and classification effects. Utility Model Content

[0011] Furthermore, the plurality of net cages are all provided with net port assemblies, and the net port assemblies on the plurality of net cages are all located on different sides, and the net port assemblies are used for quickly pouring out the fish in the net cages.
[0012] Furthermore, the network port assembly includes an outer frame and an inner frame, the inner frame is sleeved in the outer frame, each side of the outer frame is connected to the fence, the bottom of both sides of the inner frame is hinged to the bottom of both sides of the outer frame, the two side edges of the inner frame are respectively connected to the two corresponding side edges of the outer frame through the fence, and an opening inclined upward is formed between the top of the outer frame and the top of the inner frame.

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0025] See also Figure 1-6 The present embodiment provides an automated device for improving the efficiency of pond fishing and fish grading and classification, including a fishing component and a moving component, wherein the fishing component includes a plurality of frames 3, adjacent frames 3 are connected by a plurality of ropes 2, a plurality of frames 3 are provided with fishing nets 5, and the mesh sizes of the fishing nets 5 decrease in sequence according to the arrangement of the frames 3 from top to bottom, and the moving component includes a boom 1 and an adjusting mechanism 4, wherein the adjusting mechanism 4 is connected to the top of the boom 1;
[0026] The adjustment structure includes a plurality of swing rods 41, a rod sleeve 44, a gear rod 43 and a telescopic rod 42. The gear rod 43 and the telescopic rod 42 are both installed at the bottom of the top plate at the top of the boom 1. The rod sleeve 44 is sleeved on the outside of the gear rod 43. A plurality of the swing rods 41 are provided with gears on the top and the center of the circle is hinged on the axial surface of the rod sleeve 44 and rotates along the axial surface of the rod sleeve 44. The gears are meshed with the gear rod 43. The other end of the telescopic rod 42 is connected to the rod sleeve 44. The plurality of swing rods 41 swing as the telescopic rod 42 pulls the rod sleeve 44 to extend and retract, and the plurality of ropes 2 are respectively connected to the swing rod 41. The swing of the plurality of swing rods 41 is used to vibrate the fishing net 5 on the frame 3.
[0027] Since most of the fishing process still uses the traditional manual fish sorting method, that is, workers gather farmed fish together with nets, use experience to determine the fish species and the corresponding total amount, and then throw the fish into different areas surrounded by nets, resulting in high labor costs and causing water hypoxia, which in turn causes fish death. Although the grading fishing net 5 boxes in the prior art can perform preliminary classification of fish, the caught fish need to be transferred from top to bottom to the corresponding net board, and a large number of fish will block the leaks, making it difficult for smaller fish to fall onto the next level of net boards, resulting in fish of different sizes still existing on different net boards, resulting in poor grading effect;
[0028] By means of the automated device in this embodiment, fishing nets 5 with different mesh sizes are respectively arranged on a plurality of frames 3, so that the fishing nets 5 are arranged from top to bottom in descending order according to the mesh size, and all frames 3 are sequentially connected by ropes 2, so that the fishing nets 5 at different heights are parallel to each other and in a horizontal state, and the ropes 2 on the four corners of the top frame 3 are connected to the adjusting mechanism 4, and the fishing assembly is sunk into the water through the moving assembly for fishing, and the plurality of frames 3 and the fishing nets 5 on the fishing assembly can be stacked on each other in the water through the moving assembly, so that fish of different sizes fall to different In the fishing net 5, after the fishing assembly is lifted out of the water by the moving assembly, the plurality of swing rods 41 on the adjusting mechanism 4 are continuously expanded and retracted, so that the frame 3 connected to the plurality of ropes 2 and the fishing net 5 on the frame 3 form a cyclic up and down swinging movement, and the fish of different sizes on the fishing net 5 will continuously adjust their positions during the swinging process, so that the smaller fish originally at the top can move to the bottom and fall through the mesh to the next level of the fishing net 5, avoiding the smaller fish from being mixed with fish of different sizes because they cannot move, thereby achieving the effect of grading and classifying fish of different sizes and improving work efficiency.
[0029] The telescopic rod 42 on the adjustment mechanism 4 is used to make the rod sleeve 44 move up and down on the gear rod 43, driving the plurality of swing rods 41 on the rod sleeve 44 to move up and down. During the up and down movement, since the gear on the swing rod 41 is meshed with the gear rod 43, and the gear on the swing rod 41 is fixed on the swing rod 41, when the swing rod 41 moves up and down, the swing rod 41 will rotate based on the hinge point between the swing rod 41 and the rod sleeve 44. When the plurality of swing rods 41 move at the same time, the swing rod 41 will be expanded and retracted. Therefore, the fishing net 5 can vibrate up and down.
[0030] Since the fishing net 5 is only arranged on each frame 3 in the horizontal plane in the above embodiment, during the fishing process, several frames 3 can only be stacked in the water, and the multiple frames 3 on the fishing assembly are unfolded only when the fish are finally scooped up, resulting in low fishing efficiency. At the same time, some fish will leak out from both sides of the frame 3. In order to avoid this problem, in one embodiment, adjacent frames 3 are connected by a purse seine 7, and the adjacent frames 3 are enclosed by the fishing net 5 and the purse seine 7 to form a plurality of net cages respectively;
[0031] When the sides of adjacent frames 3 are enclosed by the purse net 7, the space between adjacent frames 3 can form a net cage. After the fishing assembly is placed in the water, not only can several frames 3 be stacked on each other, but the fishing assembly can also be suspended in the water through the moving assembly. Since the adjacent frames 3 are enclosed by the purse net 7, the fish only have the top fishing net 5 as an entrance, so that smaller fish cannot escape after entering the corresponding net cage. Therefore, the fishing assembly can be placed in the water for a long time, thereby extending the fishing time and improving the fishing efficiency. At the same time, since the purse net 7 is set, the fish cannot leak out from the sides between the frames 3 when the fishing assembly is lifted by the moving assembly.
[0032] In one embodiment, the adjusting mechanism 4 includes a plurality of winches 45, which are respectively arranged on the rocker 41, and the plurality of winches 45 are respectively connected to the plurality of ropes 2, and the adjusting mechanism 4 is used to adjust the tilt direction of the plurality of frames 3; after each rope 2 is connected to the winch 45 one by one, the plurality of winches 45 will sequentially extend the length of the rope 2 and then retract it, and during this process, the states of the other winches 45 remain unchanged, and each winch 45 sequentially extends and retracts the rope 2, which will cause each corner of the frame 3 below the rope 2 to rise or fall in turn, so that the fish in the fishing net 5 can be flipped according to the swinging action, so that the fish at the top can be flipped to the bottom and fall through the mesh to the fishing net 5 below, and at the same time, the rotation of the winch 45 can be used to raise and lower the fishing assembly.
[0033] Since the adjacent frames 3 are enclosed by the purse seine 7, the caught fish need to be manually separated from the rope 2 and the frame 3 before the graded and classified fish can be poured into the corresponding fish box, resulting in low work efficiency. Therefore, in one embodiment, a plurality of net cages are provided with a net opening assembly 6, the net opening assembly 6 includes an outer frame 61, each side of the outer frame 61 is connected to the purse seine 7, an opening is provided in the center of the outer frame 61, and the net opening assembly 6 on the plurality of net cages is located on different sides, and the net opening assembly 6 is used for quickly pouring out the fish in the net cage;
[0034] That is, an outer frame 61 is provided on the enclosure 7 in each net cage, and because the outer frames 61 of different net cages are located on different sides, and the adjusting mechanism 4 can adjust the length of the corresponding rope 2 through a plurality of winches 45, after the fish is caught out of the water, the rope 2 is extended by using the two winches 45 on one side of the net cage at the top with the outer frame 61, so that the height of the side is lowered, and the fish in the net cage can be poured into the fish box through the opening in the center of the outer frame 61 without manual operation, thereby improving convenience and work efficiency.
[0035] Since an outer frame 61 is arranged on the side fence 7 of the net cage, an opening is formed in the center of the outer frame 61, which may cause some fish to enter the net cage and then escape again through the opening when the fishing assembly is in the water, resulting in a decrease in fishing efficiency. In order to avoid this problem, in one embodiment, the net mouth assembly 6 also includes an inner frame 62, the inner frame 62 is sleeved in the outer frame 61, the bottoms of both sides of the inner frame 62 are hinged to the bottoms of both sides of the outer frame 61, the two sides of the inner frame 62 are respectively connected to the two corresponding sides of the outer frame 61 through the fence 7, the fence 7 is arranged in the center of the inner frame 62, and an opening inclined upward is formed between the top of the outer frame 61 and the top of the inner frame 62;
[0036] By setting an inner frame 62 and connecting both side edges of the inner frame 62 to the outer frame 61 through the fence 7, the size of the opening can be reduced. At the same time, the opening of the mesh port assembly 6 will be in a closed state when there is no external force in the water, and can be in an open state under the action of gravity after coming out of the water. When the mesh port assembly 6 is in a closed state, the inner frame 62 and the outer frame 61 overlap on the lateral projection surface, and the fence 7 connecting the inner frame 62 and the side of the outer frame 61 is in a folded state. In the open state, the inner frame 62 rotates based on the hinge point with the outer frame 61, so that the top of the inner frame 62 moves a certain distance outward, so that the fence 7 connecting the inner frame 62 and the side of the outer frame 61 is unfolded and forms an opening inclined upward.
[0037] In one embodiment, a slide groove with an opening facing the top of the outer frame 61 is provided at the top of the inner frame 62, and a groove is provided at the corresponding position of the opening of the outer frame 61. A lock buckle is provided in the slide groove, and the lock buckle includes a spring 621 and a ball 622. One end of the spring 621 abuts against the bottom of the slide groove, and the other end abuts against the ball 622. The ball 622 abuts against the inner wall of the opening and extends out of the opening and abuts against the groove.
[0038] By setting the lock, the outer frame 61 and the inner frame 62 can be kept in a closed state when in the water. After the fish are caught and taken out of the water, the net cage will be tilted to the side with the net mouth assembly 6 when the fish are poured out, and the fish will gather on this side under the action of gravity. Therefore, the squeezing of the seine 7 on the inner frame 62 by the fish will cause the ball 622 on the lock to be squeezed and moved downward by the horizontal force, so that the lock is unlocked, so that the caught fish can be poured into the fish box through the opening, so that the net mouth assembly 6 is in a closed state in the water and in an open state when the fish are poured out.
[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
