Description

Technical Field

[0001] The utility model relates to the field of net casting devices, in particular to a net casting device for ocean fishing vessels. Background Art

[0002] The net-casting device used in fishing boats can help fishermen spread the fishing nets quickly and evenly on the sea to catch fish. It can improve fishing efficiency, save manpower and time, ensure that the fishing nets are spread evenly, and reduce losses. It is an indispensable and important device in fishing operations of fishing boats.

[0003] In order to improve the efficiency of spreading the net when casting the net, it is necessary to use a fishing boat net casting device to cast the net. For example, the prior art Chinese patent publication number "CN108271746B" discloses a ship net casting and fishing device, which adopts a new electric control mechanical structure design and designs two sets of synchronously working electric control falling devices. The rotating drive motors working synchronously with each other are used to drive the connected drive gears to rotate, and the tooth pattern of the drive gear and the screw rod is engaged to control the two screw rods to move in a straight line along the casing. At the same time, the opening edge of the fishing net is connected to the two screw rods by a fixed connection at the bottom and a float at the top. When the two screw rods work synchronously with each other, the net casting, dragging fishing and net collecting operations of the fishing net are realized. The whole process is fully automated and controlled, which effectively improves the work efficiency of fishing.

[0004] Some fishing boats use a pair of worm gears to set up a fishing net at the rear for fishing. However, in actual operation, the fishing net set up in this way follows the fishing boat and is affected by the waves and the propeller, resulting in low efficiency of setting the net, which is not conducive to improving the fishing efficiency of the fishing boat.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-5 A net casting device for an ocean fishing vessel comprises a support frame 1, a fixing seat 2 is fixedly installed at the bottom of one end of the support frame 1, a winding wheel 4 is rotatably connected to the top of the other end of the support frame 1 through a round rod 3, and a mounting box 5 is fixedly installed beside the winding wheel 4, a turntable 6 for accommodating a fishing net is provided at the bottom of the other end of the support frame 1, a pair of wire grooves are opened on the side of the mounting box 5, the pair of wire grooves provide activity space for the transmission belt 78 and the fishing net, and the wire end of the fishing net is fixed to the winding wheel 4 through the wire grooves.

[0024] It is worth mentioning that before casting the net, the winding wheel 4 is rotatably connected to the round rod 3. This has the advantage that when the motor 71 drives the turntable 6 to rotate, it does not affect the winding wheel 4 and the fishing net. When the net needs to be reeled in, the winding wheel 4 is fixed by the clamping part 8 and driven by the motor 71 to reel in the fishing net.

[0025] A driving assembly 7 for driving the round rod 3 and the turntable 6 to rotate is provided at the bottom of one end of the support frame 1 , and a clamping member 8 for fixing the winding wheel 4 is provided inside the round rod 3 .

[0026] Specifically, the driving assembly 7 includes a motor 71 , and the motor 71 is fixedly mounted on the bottom of one end of the support frame 1 . The shaft end of the motor 71 passes through the support frame 1 and is fixedly connected to the end of the round rod 3 .

[0027] Furthermore, the center point of the installation box 5 is rotatably connected with a hollow tube 72, the bottom of the hollow tube 72 passes through the installation box 5 and the support frame 1 and is fixedly connected to the top of the turntable 6, a small gear 73 is fixedly installed on the top of the hollow tube 72, a large gear 75 is fixedly installed in the installation box 5 through a straight rod 74, the small gear 73 meshes and rotates with the large gear 75, one end of the hollow tube 72 passes through the turntable 6, the fishing net passes through the hollow tube 72 and the wire groove and is connected to the winding wheel 4. It is worth mentioning that the large transmission ratio of the large gear 75 can drive the small gear 73 to drive the turntable 6 to rotate quickly, thereby achieving the purpose of throwing the fishing net flying disc 61.

[0028] In more detail, a driving pulley 76 is fixedly installed at one end of the round rod 3 below the winding wheel 4, and a driven pulley 77 is fixedly installed at the bottom of the straight rod 74. A transmission belt 78 is sleeved between the driving pulley 76 and the driven pulley 77. The motor 71 drives the driving pulley 76 to cooperate with the straight rod 74 to drive the driven pulley 77 to rotate, thereby rotating the turntable 6.

The blocks 85 can be inserted into the slots 84. Because the winding wheel 4 is rotatably connected to the round rod 3, the blocks 85 can be inserted into the slots 84 to cooperate with the stop blocks 81 to fix the winding wheel 4.

[0031] Finally, the rotating disk 6 has a fishing net disc 61 clamped inside, and a pair of elastic buckles 62 are fixedly installed on the inner side thereof. Notches 63 are provided on both sides of the fishing net disc 61, and the elastic buckles 62 can clamp the notches 63. When the rotating disk 6 rotates rapidly, the fishing net disc 61 is separated from the elastic buckles 62 and rotates in the air under the action of inertia, and the fishing net will open in the air and fall into the water due to the rotation. The elastic buckles 62 are fixedly installed on the top of the inner wall of the rotating disk 6. A support plate 621 is located on one side of the hollow tube 72, and a plug rod 622 is slidably connected to the bottom of the support plate 621. A lead block 623 is provided at one end of the plug rod 622 and a tension spring is provided on the shaft end. Both ends of the tension spring are fixedly connected to the sides of the support plate 621 and the lead block 623 respectively. A slot block 624 is provided at the top of the fishing net flying disc 61, and one end of the plug rod 622 can be inserted into the slot block 624 to fix the fishing net flying disc 61.

[0032] Working mode: When working, the motor 71 drives the turntable 6 to rotate so that the fishing net flying disc 61 flies out and opens the fishing net, and then the stop block 81 is clamped into the straight groove 41 and the clamping block 85 is inserted into the clamping groove 84 to achieve the function of fixing the winding wheel 4, and the motor 71 drives the winding wheel 4 to retract the fishing net.
