Description

Technical Field

[0001] The invention relates to the technical field of dead fish salvaging, and in particular to dead fish salvaging equipment used in aquaculture. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture has extensive farming, intensive farming and high-density intensive farming. Extensive farming is to release seedlings in medium and small natural waters and grow aquatic products completely with natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is to grow aquatic products in smaller water bodies by feeding and fertilizing, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density farming of fish and shrimp in flowing water. In the process of aquaculture, dead fish often appear in fish ponds.

[0003] The patent with the authorization announcement number CN 214508888 U discloses a dead fish salvaging device for aquaculture, which includes a support plate. The salvaging rod can be flexibly adjusted by the cooperation of the support plate, multiple cylinders, rotating shafts, moving grooves, rotating rods and clamping plates, so that people do not need to hold a scoop net to salvage dead fish all the time, which reduces the work intensity of the staff. The dead fish salvaged by the wire net can be directly transported to the ship through the holding seat and the slideway by pressing the handle, so that the dead fish can be poured from the filter net to the ship without having to operate the salvage rod drastically every time, which is very convenient and quick.

[0004] However, the above patent still has the following problems: when the dead fish is salvaged with a scoop net and placed on the holding seat, if the dead fish is perpendicular to the moving trough or the dead fish is obliquely blocked at the entrance of the slideway, the dead fish cannot fall onto the boat along the slideway, thereby affecting the salvage of the staff;

[0005] At the same time, a large number of saprophytic microorganisms will gather around the dead fish. They are mainly responsible for decomposing the fish carcasses. The number of these microorganisms around the dead fish will be much greater than that in other areas. The metabolic activities of these microorganisms will change the chemical properties of the surrounding water, such as producing acidic substances, further affecting the water quality.

[0006] At the same time, the microorganisms around the dead fish will multiply in large numbers to decompose the fish carcasses. The respiration of microorganisms requires oxygen consumption, so the dissolved oxygen content around the dead fish will be lower than that in other areas. For example, the dissolved oxygen in normal fish pond water may be 5mg / L-8mg / L. Around the dead fish, due to the intense decomposition activity of microorganisms, the dissolved oxygen may drop to below 2mg / L, or even lower, forming a local hypoxic environment. In areas far away from the dead fish, the consumption of dissolved oxygen is not so serious, and the content is relatively high. The above patents are not convenient for cleaning the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) in the water around the dead fish while salvaging the dead fish, and they are also unable to stir and oxygenate the water around the dead fish. Therefore, in view of the above problems, a dead fish salvaging device for aquaculture is proposed. Summary of the invention

[0021] The microorganisms and microbial metabolites are temporarily stored inside the cleaning net. After the dead fish is salvaged by the salvage frame, the side plates and the stirring rod are rapidly rotated back and forth in the water around the dead fish. The water around the dead fish can be rapidly mixed with the water in other areas through the rapid stirring of the side plates and the stirring rod, thereby increasing the oxygen content of the water around the dead fish.

At the same time, the cleaning net 111 can automatically fall to the inner side of the collection barrel 13 under the gravity of the counterweight column 112, so that the cleaning net 111 is turned upside down on the inner side of the collection barrel 13, so that the side with suspended particles (microorganisms, microbial metabolites and fish carcass fragments) attached to it can face the collection barrel 13, and then the cleaning net 111 is rotated rapidly, and the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) attached to the inner side of the cleaning net 111 are thrown to the inner side of the collection barrel 13 under the action of centrifugal force, thereby preventing the cleaning net 111 from being blocked, and also preventing the growth of microorganisms, ensuring the normal operation of the cleaning net 111, and the collection barrel 13 can realize the centralized collection and treatment of suspended particles (microorganisms, microbial metabolites and fish carcass fragments);

[0051] When the cleaning net 111 needs to work normally, the staff can pull the counterweight column 112 through the first pull rope 113 to make the counterweight column 112 re-enter the inner side of the limiting cylinder 114. At the same time, the counterweight column 112 will also reset the cleaning net 111, so that the cleaning net 111 can continue to salvage suspended particles (microorganisms, microbial metabolites and fish carcass fragments) around the dead fish.

[0052] As a further improvement of the present invention, Figure 2 , Fig. 9 and Fig.10 As shown, the anti-blocking mechanism 2 includes a roller 204 rotatably connected to the salvage frame 10, one end of the roller 204 is fixedly connected to the third crossbeam 213, one end of the third crossbeam 213 is rotatably connected to the first guide wheel 208, one end of the third crossbeam 213 is fixedly connected to the second crossbeam 212, and the second crossbeam 212 is fixedly connected to the roller 204, one end of the second crossbeam 212 is fixedly connected to the adjustment plate 203, and the adjustment plate 203 is fixedly connected to the roller 204, a stopper 214 is provided on one side of the adjustment plate 203, and the stopper 214 is fixedly connected to the salvage frame 10, the stopper 214 plays a role of resisting and limiting the adjustment plate 203, one end of the adjustment plate 203 is fixedly connected to the second pull rope 202, and the outer side of the second pull rope 202 is slidably connected to the second fixed plate 201, and the second fixed plate 201 is fixedly connected to the conveying frame 9, and the other end of the second pull rope 202 is fixedly connected to the pull ring 20 7. When the dead fish is in a vertical state with the conveying frame 9 or is placed obliquely on the inner side of the salvage frame 10, when the dead fish slides downward along the salvage frame 10, the first guide wheel 208 plays a role of resisting and correcting one end of the dead fish, so that the other end of the dead fish slides downward first, ensuring that the dead fish will not be horizontally located at the entrance of the conveying frame 9, thereby ensuring that the dead fish can slide normally to the inner side of the hull 3 along the conveying frame 9, and when the dead fish stays on one side of the first guide wheel 208 and cannot slide downward, the staff pulls the second pull rope 202 through the pull ring 207, so that the second pull rope 202 drives the roller 204 to rotate clockwise from top to bottom through the adjustment plate 203, and then the roller 204 drives the second guide wheel 209 to rotate toward the dead fish through the second crossbeam 212, and the dead fish is pushed by the second guide wheel 209 to shake, and the shaking of the dead fish gradually corrects the position of the dead fish and slides to the inner side of the conveying frame 9.

[0053] As a further improvement of the present invention, Fig.10As shown, one end of the second crossbeam 212 is fixedly connected to the first crossbeam 211, and the other end of the first crossbeam 211 is fixedly connected to the guide plate 210, and the two ends of the guide plate 210 are rotatably connected to the first guide wheel 208 and the second guide wheel 209 respectively. When the second crossbeam 212 rotates, it will also rotate with the guide plate 210 through the first crossbeam 211, so that after one end of the dead fish is separated from the first guide wheel 208, the guide plate 210 can continue to support and guide one end of the dead fish, ensuring that the second guide wheel 209 can smoothly push one end of the dead fish.

[0054] As a further improvement of the present invention, Fig.11 As shown, the top of the roller 204 is fixedly connected with a rotating shaft 205, and the rotating shaft 205 is rotatably connected to the salvage frame 10. A torsion spring 206 is arranged on the outside of the rotating shaft 205, and the two ends of the torsion spring 206 are respectively fixedly connected to the roller 204 and the salvage frame 10, and the torsion spring 206 provides a force for the roller 204 to rotate counterclockwise when viewed from top to bottom. Under the action of the torsion force of the torsion spring 206, when the second guide wheel 209 is not in use, the second guide wheel 209 can be moved out from the inner side of the salvage frame 10 under the action of the torsion force of the torsion spring 206, so that the first guide wheel 208 can work normally.

[0055] Working process: when salvaging dead fish, the first servo motor 102 moves the inner ring 108 and the outer ring 107 to the bottom of the salvage frame 10 through the cylinder 103, the rotating cylinder 105, the connecting plate 106 and the middle plate 117, and the cleaning net 111 also moves to the bottom of the cleaning net 111 with the inner ring 108, and the relative position between the salvage frame 10 and the dead fish can be changed by adjusting the position of the hull 3 in the water to ensure that the salvage frame 10 can accurately salvage the dead fish. When the salvage frame 10 salvages the dead fish, the fourth servo motor 5 is connected to the middle plate 117 to move the inner ring 108 and the outer ring 107 to the bottom of the cleaning net 111. The connecting block 6 can rotate around the rotating shaft of the connecting block 6 with the conveying frame 9 and the salvaging frame 10, so that the conveying frame 9 can salvage the dead fish from the bottom of the water to the surface of the water with the salvaging frame 10. At the same time, the conveying frame 9 can also move with the cleaning net 111 through the first fixing plate 101, the cylinder 103, the rotating cylinder 105, the connecting plate 106, the outer ring 107 and the inner ring 108. While the dead fish are salvaged by the salvaging frame 10, the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) in the water around the dead fish can also be salvaged by the cleaning net 111.

[0056] After the salvage frame 10 salvages the dead fish to the inner side of the salvage frame 10, when the inner ring 108 needs to rotate with the side plate 115 and the stirring rod 116, the third servo motor 120 drives the push plate 122 to reciprocate through the rotating plate 121, and at the same time, the push plate 122 also drives the rack 119 to reciprocate along the rotating drum 105 and the middle plate 117. When the rack 119 reciprocates, the rack 119 drives the gear 118 to reciprocate, and then the gear 118 drives the inner ring 108 to reciprocate through the gear ring 109, and then the inner ring 108 drives the cleaning net 111, the side plate 115 and the stirring rod 116 to reciprocate together, and there is no need to manually drive the cleaning net 111, the side plate 115 and the stirring rod 116 to reciprocate, which is convenient for the staff. The side plate 115 and the stirring rod 116 can be used to stir the dead fish quickly, and the water around the dead fish can be quickly mixed with the water in other areas, thereby increasing the oxygen content of the water around the dead fish. Oxygenation can make the environmental conditions unfavorable for the growth of some anaerobic harmful microorganisms (such as Desulfurization Vibrio that produces harmful substances such as hydrogen sulfide). After the stirring is completed, the conveying frame 9 can rotate upward with the salvaging frame 10, so that the dead fish inside the salvaging frame 10 slides along the conveying frame 9 to the inside of the hull 3. There is no need to manually rotate the conveying frame 9 and the salvaging frame 10, which is convenient for the staff to quickly place the dead fish on the inside of the hull 3. The staff can also place a fish frame containing dead fish in the cabin of the hull 3 to let the dead fish fall directly to the inside of the fish frame.

[0057] When the dead fish is in a vertical state with the conveying frame 9 or is placed obliquely on the inner side of the salvage frame 10, when the dead fish slides downward along the salvage frame 10, the first guide wheel 208 plays a role of resisting and correcting one end of the dead fish, so that the other end of the dead fish slides downward first, ensuring that the dead fish will not be horizontally located at the entrance of the conveying frame 9, thereby ensuring that the dead fish can slide normally toward the inner side of the hull 3 along the conveying frame 9, and when the dead fish stays on one side of the first guide wheel 208 and cannot slide downward, the staff pulls the second pull rope 202 through the pull ring 207, so that the second pull rope 202 passes through the adjustment plate 203 and brings the roller 20 4 rotates clockwise from top to bottom, and then the roller 204 rotates toward the dead fish through the second crossbeam 212 with the second guide wheel 209, and the dead fish is pushed by the second guide wheel 209 to shake the dead fish, and the dead fish is gradually corrected and slides to the inner side of the conveying frame 9 through the shaking of the dead fish. At the same time, when the second crossbeam 212 rotates, it will also rotate with the guide plate 210 through the first crossbeam 211, so that after one end of the dead fish is separated from the first guide wheel 208, the guide plate 210 can continue to support and guide one end of the dead fish, ensuring that the second guide wheel 209 can smoothly push one end of the dead fish;

[0058] When it is necessary to pour the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) inside the cleaning net 111 into the inner side of the collecting bucket 13, the first servo motor 102 is driven to move the inner ring 108 and the outer ring 107 to one side of the collecting bucket 13 through the cylinder 103, the rotating drum 105, the connecting plate 106 and the middle plate 117, and then the second servo motor 104 is driven to rotate the connecting plate 106 through the rotating drum 105, and then the connecting plate 106 is driven to rotate the outer ring 107, the inner ring 108 and the outer ring 107. The outer ring 108 and the cleaning net 111 are turned over 180 degrees, so that the outer ring 107 is turned over to the top of the collection bucket 13, and the inlet of the cleaning net 111 is facing downward. At the same time, the cleaning net 111 can automatically fall to the inside of the collection bucket 13 under the gravity of the counterweight column 112, so that the cleaning net 111 is turned upside down on the inside of the collection bucket 13, so that the side with suspended particles (microorganisms, microbial metabolites and fish carcass fragments) attached to it can face the collection bucket 13, and then the third servo motor 120 is turned on. The rotating plate 121 drives the push plate 122 to reciprocate, and the push plate 122 also drives the rack 119 to reciprocate along the rotating drum 105 and the middle plate 117. When the rack 119 reciprocates, the rack 119 drives the gear 118 to reciprocate, and then the gear 118 drives the inner ring 108 to reciprocate through the gear ring 109, and then the inner ring 108 drives the cleaning net 111 to reciprocate together. Under the action of centrifugal force, the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) attached to the inner side of the cleaning net 111 are thrown to the inner side of the collecting barrel 13, thereby preventing the cleaning net 111 from being blocked and preventing the growth of microorganisms, ensuring the normal operation of the cleaning net 111, and the collection barrel 13 can realize the centralized collection and treatment of the suspended particles (microorganisms, microbial metabolites and fish carcass fragments); after the cleaning is completed, the cleaning net 111 can be reset, so that the cleaning net 111 can continue to salvage the suspended particles (microorganisms, microbial metabolites and fish carcass fragments) around the dead fish.
