Description

Technical Field

[0001] The embodiment of the present invention belongs to the technical field of freshwater aquaculture, and in particular relates to a freshwater aquaculture fishing device. Background Art

[0002] Freshwater aquaculture refers to the production method of aquatic organisms breeding in freshwater areas such as rivers, lakes, reservoirs, and ponds. Among them, pond aquaculture is the most common aquaculture method. It is a high-density aquaculture by artificially building ponds, controlling water quality, feeding feed and other conditions. The area of ​​the pond can be determined according to the actual situation, generally ranging from a few acres to dozens of acres. Common fish such as grass carp, carp, crucian carp, silver carp, and bighead carp are usually cultured in ponds. They have the characteristics of fast growth, strong adaptability, and delicious meat.

[0003] For example, a Chinese patent document with publication number CN 204272941 U discloses a freshwater aquaculture fishing device, which includes an aquaculture pond body 1 and an intelligent mobile terminal 2. A platform 3 is provided at the center of the aquaculture pond body 1, a fishing unit is provided at the upper end of the platform 3, and a plurality of detection units are provided on the side surface of the platform 3. The detection units and the fishing units are respectively connected to the intelligent mobile terminal 2 in a wireless manner and work under its control. The fishing unit is composed of a positioning motor 4 fixedly installed on the top of the platform 3, a spray gun 5 fixedly installed at the rotating end of the positioning motor 4, a storage motor 6 arranged on the side surface of the positioning motor 4, a fishing net 7 that can be stored in the spray gun 5, a bait trap 8 fixedly installed at the center of the fishing net 7, a plurality of counterweights 9 fixedly installed at the edge of the fishing net 7, and a steel wire rope 10 arranged on the edge of the fishing net 7 and having both ends extending out of the fishing net 7 and fixedly connected to the rotating end of the storage motor 6. The scheme has a simple structure and can be used for pulling net fishing only by electric means, which saves labor and improves the efficiency of fishing.

[0004] For another example, a Chinese patent document with publication number CN 213663193 U discloses a freshwater aquaculture fishing device, comprising a bottom plate, a support plate, a fishing box and a box body, wherein the support plate is fixedly connected to the bottom plate, a stirring mechanism is provided in the box body, a first water pump is fixedly connected to the support plate, a first pipe is connected between the first water pump and the box body, a first nozzle is fixedly connected to the bottom of the support plate, a second pipe is connected between the first water pump and the first nozzle, and a slider is slidably connected in the support plate; this solution has a simple structure and is convenient to operate, and the fish feed is evenly stirred and then sprayed around the fishing box to better lure the fish into the net through the cooperation between the first motor and the first water pump, and the position of the fishing box is adjusted through the cooperation between the cylinder and the slider, thereby greatly improving the practicality.

[0005] For another example, a Chinese patent document with publication number CN 214629228 U discloses a freshwater aquaculture fishing device, comprising a floating frame, a rectangular frame is provided at the bottom of the floating frame, fixed mesh plates are provided at the front, rear and bottom of the rectangular frame, a fish inlet is provided in the middle of the fixed mesh plate, a fish taking mechanism is provided on the left side of the rectangular frame, the fish taking mechanism comprises a fixed frame, a movable plate is hingedly connected to the bottom of the inner wall of the fixed frame by a hinge, a rectangular fixed plate is provided on the right side of the rectangular frame, a mounting groove is provided in the middle of the side surface of the rectangular fixed plate, and a screening mesh plate is provided in the mounting groove; the scheme allows freshwater fish to enter the rectangular frame through the three fish inlets, and can prevent qualified freshwater fish from escaping, and under the action of the screening mesh plate, unqualified freshwater fish can swim free from the mesh holes of the screening mesh plate, thereby reducing the probability of small fish being caught 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 is impossible to achieve large-area coverage for large ponds, and the placement of the cages is relatively fixed, making it difficult to capture all the fish to be harvested in the pond at one time. Summary of the invention

[0007] The purpose of the embodiment of the present invention is to provide a freshwater aquaculture and fishing device, aiming to solve the problem that fish cannot be efficiently captured in ponds during large-scale aquaculture.

[0013] The net collecting plate comprises a net plate body and a mounting hole, wherein the mounting hole is provided on the net plate body, and the diameter of the mounting hole is smaller than the diameter of the float and the sinker and larger than the diameter of the pull rope; thus, after the pull rope is tightened, the float and the sinker will be stuck on the net plate body and cannot pass through the mounting hole, thereby realizing the closing of the trawl;

[0014] In a preferred embodiment provided by the present invention, the trawl driving mechanism comprises a pulley, the pulley is coaxially welded with the belt pulley, and the pulley is transmission-connected to the driving motor via a belt;
