Description

Technical Field

[0001] This utility model relates to the field of aquatic plant harvesting technology, specifically to a device for harvesting rotten aquatic plants used in aquaculture. Background Technology

[0002] Aquaculture is the production activity of cultivating and propagating aquatic economic plants and animals (such as fish, shrimp, shellfish, and algae) in water areas (such as ponds, lakes, and oceans). It is an important component of global food security and protein supply. Aquaculture is the production activity of breeding, cultivating, and harvesting aquatic plants and animals under human control. It generally includes the entire process from seedling to marketable aquatic products under artificial feeding and management. In a broader sense, it can also include aquatic resource enhancement.

[0003] Aquaculture includes extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves stocking seedlings in small to medium-sized natural water bodies and raising aquatic products entirely based on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as pond fish farming, net cage fish farming, and enclosure aquaculture. High-density intensive farming uses methods such as flowing water, temperature control, aeration, and feeding high-quality feed to achieve high yields through high-density farming in small bodies of water, such as high-density flowing water fish and shrimp farming.

[0004] Overfeeding, fertilizing, or aging of bottom sediment during the aquaculture process can lead to excessive nitrogen and phosphorus content in the water, causing aquatic plants to grow wildly. Once this exceeds the water's carrying capacity, the bottom aquatic plants will gradually rot due to insufficient sunlight. Excess aquatic plants that are not harvested in time will grow extremely fast during the high temperatures of summer, and if not dealt with promptly, they are very likely to accumulate and rot.

[0005] Regarding the existing related technologies, the inventor believes that there are the following drawbacks: When the existing technology is used to salvage decaying aquatic plants, it is generally done manually. Workers have to row a boat to salvage the plants, which is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0006] To address the problems of existing methods that involve workers rowing boats to collect rotten aquatic plants, which are time-consuming, labor-intensive, and inefficient, this invention provides a device for collecting rotten aquatic plants in aquaculture.

[0007] This utility model is achieved using the following technical solution: A device for harvesting decaying aquatic plants in aquaculture, comprising a hull and a harvesting frame. The hull has a storage compartment inside. Two fixed frames are fixedly connected to one end of the top of the hull. A rotating shaft is rotatably connected to one end of each fixed frame. A connecting block is fixedly connected to the outside of the rotating shaft. One end of the connecting block is fixedly connected to the harvesting frame. A hydraulic cylinder is provided at one end of the hull. A movable block is fixedly connected to one end of the hydraulic cylinder. A limit strip is fixedly connected to the top of the movable block. A rack is fixedly connected to the top of the limit strip. A gear is meshed with the top of the rack. The middle part of the rotating shaft is fixedly connected to the inside of the gear.

[0008] Preferably, a support frame is fixedly connected to one end of the top of the hull. The support frame is located on top of the storage compartment. When the salvage frame is flipped to the top of the storage compartment, the salvage frame and the support frame collide back and forth several times, which facilitates shaking the rotten aquatic plants inside the salvage frame into the storage compartment.

[0009] Preferably, a fixing plate is fixedly connected to the top of the hull, and a horizontal plate is fixedly connected to the top of the fixing plate, with the hydraulic cylinder located at the bottom of the horizontal plate.

[0010] Preferably, a limiting groove is machined on the top of the horizontal plate, and the limiting strip is movably connected inside the limiting groove. The limiting groove will limit the movement of the limiting strip, thereby keeping the rack in a stable state when it moves.

[0011] Preferably, two guide plates are fixedly connected to the bottom ends of the movable block. A guide rod is fixedly connected to one end of each fixed plate. The guide plate is movably connected to the outside of the guide rod. By providing the guide rod, the guide rod will limit the movement of the guide plate, thereby keeping the movable block in a stable state when it moves.

[0012] Preferably, the bottom of the storage compartment is machined with multiple water filter holes around its perimeter, which facilitates the drainage of water accumulated inside the storage compartment.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, this invention moves the scooping frame forward via the hull, allowing it to collect decaying aquatic plants. Once the scooping frame is full, the hydraulic cylinder is activated. This cylinder moves the movable block, limit strip, and rack. The rack's movement drives the gear and shaft to rotate, which in turn drives the connecting block and scooping frame to rotate around the shaft. This process pours the decaying aquatic plants from the scooping frame into the collection chamber. The operation is simple, convenient, and highly efficient. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a device for harvesting decaying aquatic plants for aquaculture includes a hull 1 and a harvesting frame 2. The hull 1 has a storage compartment 3 inside. Two fixed frames 6 are fixedly connected to one end of the top of the hull 1. A rotating shaft 13 is rotatably connected to one end of the fixed frame 6. A connecting block 7 is fixedly connected to the outside of the rotating shaft 13. One end of the connecting block 7 is fixedly connected to the harvesting frame 2. A hydraulic cylinder 8 is provided at one end of the hull 1. A movable block 9 is fixedly connected to one end of the hydraulic cylinder 8. A limit strip 10 is fixedly connected to the top of the movable block 9. A rack 11 is fixedly connected to the top of the limit strip 10. A gear 12 is meshed with the top of the rack 11. The middle part of the rotating shaft 13 is fixedly connected to the inside of the gear 12.

[0021] When it is necessary to salvage decaying aquatic plants, the hull 1 is moved to the location where the decaying aquatic plants are present. The hull 1 will drive the salvage frame 2 forward, thereby collecting the decaying aquatic plants into the interior of the salvage frame 2. When the interior of the salvage frame 2 is full of decaying aquatic plants, the hydraulic cylinder 8 is activated. The hydraulic cylinder 8 will drive the movable block 9 to move, the movable block 9 will drive the limit strip 10 to move, the limit strip 10 will drive the rack 11 to move, the rack 11 will drive the gear 12 to rotate, the gear 12 will drive the rotating shaft 13 to rotate, the rotating shaft 13 will drive the connecting block 7 to rotate, and the connecting block 7 will drive the salvage frame 2 to rotate around the rotating shaft 13 as the center, causing the salvage frame 2 to rotate and flip to the top of the collection bin 3, thereby pouring the decaying aquatic plants collected by the salvage frame 2 into the interior of the collection bin 3. Then the salvage frame 2 is reset to continue collecting. The operation is simple and convenient.

[0022] Furthermore, a support frame 4 is fixedly connected to one end of the top of the hull 1. The support frame 4 is located on the top of the storage compartment 3. When the salvage frame 2 is flipped to the top of the storage compartment 3, one end of the salvage frame 2 contacts the support frame 4. Then, the salvage frame 2 and the support frame 4 collide back and forth several times to facilitate shaking the rotten aquatic plants inside the salvage frame 2 into the storage compartment 3.

[0023] Furthermore, a fixed plate 14 is fixedly connected to the top of the hull 1, and a horizontal plate 15 is fixedly connected to the top of the fixed plate 14. The hydraulic cylinder 8 is located at the bottom of the horizontal plate 15, and a limit groove 16 is machined on the top of the horizontal plate 15. The limit strip 10 is movably connected inside the limit groove 16.

[0024] When the movable block 9 drives the limit bar 10 to move, the limit bar 10 will move along the inside of the limit groove 16. The limit groove 16 will limit the movement of the limit bar 10, so that the rack 11 will remain stable when it moves. The movement of the limit bar 10 will drive the rack 11 to move along the top of the horizontal plate 15.

[0025] Furthermore, two guide plates 17 are fixedly connected to the bottom ends of the movable block 9, and a guide rod 18 is fixedly connected to one end of the fixed plate 14. The guide plate 17 is movably connected to the outside of the guide rod 18. When the hydraulic cylinder 8 drives the movable block 9 to move, the movable block 9 will drive the guide plate 17 to move. The guide plate 17 will move along the outside of the guide rod 18. By providing the guide rod 18, the guide rod 18 will limit the movement of the guide plate 17, thereby keeping the movable block 9 in a stable state when it moves.

[0026] Furthermore, the bottom of the storage compartment 3 is machined with multiple water filter holes 5 around its perimeter, which facilitates the drainage of water accumulated inside the storage compartment 3.

[0027] Working principle: The hull 1 drives the salvage frame 2 forward, allowing it to collect decaying aquatic plants. Once the salvage frame 2 is full, the hydraulic cylinder 8 is activated. The hydraulic cylinder 8 drives the movable block 9, the limit bar 10, and the rack 11. The rack 11 drives the gear 12 to rotate, which in turn drives the rotating shaft 13. The rotating shaft 13 then drives the connecting block 7 and the salvage frame 2 to rotate around the shaft 13, causing the salvage frame 2 to flip to the top of the collection bin 3. This allows the decaying aquatic plants inside the salvage frame 2 to be poured into the collection bin 3. The salvage frame 2 then returns to its original position to continue collecting. The operation is simple, convenient, and highly efficient.

[0028] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
