Description

Technical Field

[0001] This utility model relates to the field of anti-scratch fishing technology, specifically to an anti-scratch fishing device for salmon and trout. Background Technology

[0002] With the gradual improvement of people's living standards, the aquaculture industry is also developing better and better. Fishing machinery is a general term for mechanical equipment used in fishing operations to operate fishing gear and catch or retrieve fish from the water. Fishing equipment is frequently used in aquaculture. As salmon and trout farming scales up, a farming model from land-based seedling cultivation to deep-sea rearing is gradually taking shape. To facilitate cross-plant sorting or land-sea transfer of salmon and trout from land-based farming, frequent transfer operations are necessary.

[0003] As shown in the announcement number CN 216874608 U, a fishing device includes a net body, a hanging assembly disposed on opposite sides of the net body, and an extension rod detachably disposed on the net body and located in the middle of the hanging assembly. This device does not have a manual lifting and adjusting mechanism. The height of the fishing device can be adjusted by the operator simply turning the rotating handle, which is achieved through the traction transmission between the components. The operation is simple and easy to understand. However, the operation of this device requires the operator to manually fish, which is time-consuming and labor-intensive, further reducing work efficiency. Moreover, using conventional fishing nets for fishing will cause varying degrees of scratches to salmon and trout. Utility Model Content

[0004] The purpose of this invention is to provide a scratch-resistant fishing device for salmon and trout, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A salmon and trout fishing device designed to prevent scratching includes a fixed frame. A lifting and adjusting mechanism is movably mounted at the bottom of the fixed frame. The lifting and adjusting mechanism includes an auxiliary pulley, a fixed rod, a traction rope, a movable guide wheel, and a mounting plate. The auxiliary pulley is movably mounted at the bottom of the fixed frame. A fixed rod is fixedly mounted inside the auxiliary pulley. A traction rope is movably mounted outside the fixed rod. One end of the traction rope is fixedly connected to the inside of the auxiliary pulley. A movable guide wheel is movably mounted at the bottom of the traction rope. Mounting plates are fixedly mounted on both sides of the bottom of the movable guide wheel. A connecting block is provided at the bottom of the mounting plate. The connecting block has a threaded groove inside. A fixing screw is movably mounted on the side of the bottom of the mounting plate, and the fixing screw is movably connected to the threaded groove.

[0007] Preferably, a fishing box is fixedly installed at the bottom of the connecting block. An inlet is opened on one side of the fishing box. A knotless net is fixedly installed inside the fishing box and the inlet. A cover door is movably installed on the other side of the fishing box via a hinge. Salmon and trout enter the fishing box through the inlet. Due to the restriction of the knotless net, the salmon and trout are not easy to escape and can be protected from scratches. The cover door makes it easy for workers to take out the salmon and trout from the fishing box.

[0008] Preferably, a fixing plate is fixedly installed at the top of the fixing frame, and a threaded hole is opened on one side of the fixing plate. The fixing plate is fixed at a high position of the hull by screws passing through the threaded hole to ensure its stability.

[0009] Preferably, a sleeve is movably provided at one end of the traction rope, a large gear is movably provided on the side of the sleeve, a small gear is movably provided on the side of the large gear, and a control handle is movably provided on the side of the small gear. The operator manually rotates the handle, and the small gear drives the large gear to rotate, thereby controlling the length adjustment of the traction rope.

[0010] Preferably, the sleeve is provided with a protective shell, and a through hole is provided on one side of the protective shell. The through hole is movably connected to the traction rope. The protective shell makes the entire traction process of the device smoother, and the through hole allows the traction rope to move freely.

[0011] Preferably, support rods are fixedly installed on both sides of the outer side of the protective shell, and a mounting block is fixedly installed on one side of the bottom end of the support rod. An expansion screw is movably installed inside the mounting block. The support rod is fixed to the ship plate by the expansion screw, thereby fixing the position of the protective shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This salmon and trout fishing device uses an anti-scratch fishing mechanism. First, a fixing plate is secured to a high point on the hull using screws through threaded holes to ensure stability. Then, expansion bolts are used to fix the support rod to the hull plate, thus securing the protective shell. The operator manually rotates the control handle, causing a small gear to drive a large gear, which in turn rotates a sleeve on the side of the large gear. This controls the contraction and extension of the traction rope. If the fishing box needs to be lowered and the traction rope pulled away, the auxiliary pulley remains in a constant position, so loosening the traction rope causes the movable guide wheel to move downwards, lowering the fishing box to the bottom. Conversely, rotating the control handle in the opposite direction contracts the traction rope, raising the fishing box. The knotless design prevents salmon and trout from escaping once inside the fishing box.

[0014] 2. This salmon and trout fishing device uses a scratch-resistant fishing method. The device has a manual lifting and adjusting mechanism. The height of the fishing device can be adjusted by simply turning the rotating handle and the traction transmission between the various parts. The operation is simple and easy to understand. Unlike the previous manual throwing and retrieval method, this method is more time-saving and labor-saving, which reduces the workload of the staff to a certain extent and thus significantly improves work efficiency. The knotless net design also provides scratch protection for the salmon and trout to a certain extent. Attached Figure Description

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0023] The salmon and trout fishing device uses a scratch-resistant fishing method, including a fixed frame 1. The bottom of the fixed frame 1 is movably equipped with a lifting and adjusting mechanism, which includes an auxiliary pulley 2, a fixed rod 3, a traction rope 4, a movable guide wheel 5, and a mounting plate 6. The auxiliary pulley 2 is movably equipped at the bottom of the fixed frame 1. The fixed rod 3 is fixedly installed inside the auxiliary pulley 2. The traction rope 4 is movably installed outside the fixed rod 3. One end of the traction rope 4 is fixedly connected to the inside of the auxiliary pulley 2. The movable guide wheel 5 is movably equipped at the bottom of the traction rope 4. The mounting plate 6 is fixedly installed on both sides of the bottom of the movable guide wheel 5. The bottom of the mounting plate 6 is equipped with a connecting block 7. The connecting block 7 has a threaded groove 8 inside. The bottom side of the mounting plate 6 is movably equipped with a fixing screw 9, which is movably connected to the threaded groove 8.

[0024] In this embodiment, preferably, a fishing box 10 is fixedly installed at the bottom of the connecting block 7. An inlet 11 is opened on one side of the outside of the fishing box 10. A knotless net 12 is fixedly installed inside the fishing box 10 and the inlet 11. A cover door 24 is movably installed on the other side of the outside of the fishing box 10 via a hinge. The salmon and trout enter the inside of the fishing box through the inlet. Due to the restriction of the knotless net, the salmon and trout are not easy to escape and can be protected from scratches. The cover door makes it easy for workers to take out the salmon and trout from the fishing box.

[0025] In this embodiment, preferably, a fixing plate 13 is fixedly installed at the top of the fixing frame 1, and a threaded hole 14 is opened on one side of the fixing plate 13. The fixing plate is fixed at a high position of the hull by screws passing through the threaded hole to ensure its stability.

[0026] In this embodiment, preferably, a sleeve block 15 is movably provided at one end of the traction rope 4, a large gear 16 is movably provided on the side of the sleeve block 15, a small gear 17 is movably provided on the side of the large gear 16, and a control handle 18 is movably provided on the side of the small gear 17. The operator manually rotates the handle, and the small gear drives the large gear to rotate, thereby controlling the length adjustment of the traction rope.

[0027] In this embodiment, preferably, a protective shell 19 is provided on the outside of the sleeve block 15, and a through hole 20 is provided on one side of the protective shell 19. The through hole 20 is movably connected to the traction rope 4. The setting of the protective shell makes the entire traction process of the device smoother, and the traction rope can move freely by using the through hole.

[0028] In this embodiment, preferably, support rods 21 are fixedly provided on both sides of the outer side of the protective shell 19, and a mounting block 22 is fixedly provided on one side of the bottom end of the support rod 21. An expansion screw 23 is movably provided inside the mounting block 22. The support rod is fixed to the ship plate by the expansion screw, thereby fixing the position of the protective shell.

[0029] In this embodiment, the salmon and trout transfer anti-scratch fishing device is used by first fixing the fixing plate 13 to the high part of the hull with screws through the threaded hole 14 to ensure its stability. At this time, the support rod 21 is fixed to the hull plate with expansion screws 23, thereby fixing the position of the protective shell 19. The operator manually turns the control handle 18, and the small gear 17 drives the large gear 16 to rotate, which causes the sleeve 15 on the side of the large gear 16 to rotate, thereby controlling the contraction and extension of the traction rope 4. If it is necessary to lower the fishing box 10 to pull out the traction rope 4, since the position of the auxiliary pulley 2 remains unchanged, the loosening of the traction rope 4 will cause the movable guide wheel 5 to move downward, thereby driving the fishing box 10 to sink to the bottom of the water. Conversely, rotating the control handle 18 in the opposite direction can retract the traction rope 4, raising the fishing box 10. The knotless net 12 is designed to prevent salmon and trout from escaping once they enter the fishing box 10 and to protect them from scratches. Finally, the staff opens the cover door to retrieve the salmon and trout. The device has a manual lifting and adjusting mechanism. The staff only needs to turn the rotating handle to adjust the height of the fishing device through the traction transmission between the components. The operation is simple and easy to understand. Unlike the previous manual throwing and retrieval method, this method is more time-saving and labor-saving, reducing the workload of the staff to a certain extent and thus significantly improving work efficiency. The knotless net design also provides some protection against scratches to the salmon and trout.
