Description

Technical Field

[0001] The invention relates to the technical field of fish conveying on fishing vessels, and in particular to a fish conveying device on board. Background Art

[0002] In the current tuna purse seine fishing operation, hundreds of tons of tuna can be caught in one operation. However, the transfer process of tuna still relies heavily on manpower. For example: 1. When tuna is stored in the frozen fish hold, it needs manpower to be put in, but in this process, the staff are required to maintain a high degree of concentration and a fast reaction speed to cope with the constantly flowing fish school. However, with the increase in the catch, the labor intensity of this method has increased sharply, and the staff will soon feel tired, resulting in a decrease in handling efficiency. 2. When tuna is moved out of the frozen fish hold, the staff needs to use a crane to move the frozen tuna out of the hold. However, the limited space in the frozen fish hold, poor visibility, and ice cover increase the safety risks during the operation. In addition, in the process of salvaging out of the hold, due to the slippery surface of the tuna and the uneven weight distribution, it is easy to slip or collide and other accidents, which may not only cause damage to the tuna and affect the quality, but also may cause harm to the staff. At the same time, due to the low speed and efficiency of manually salvaging tuna out of the hold, the turnover rate of the frozen fish hold will decrease, affecting the overall operation progress. 3. Due to the wear and aging of the conveyor belt after long-term use, it is easy to cause the track to loosen and even deviate or break. This not only affects the stability and reliability of the conveyor belt, but may also cause the tuna to slip or be damaged during transportation, thereby increasing the frequency and difficulty of manual intervention. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fish conveying device on board which can reduce the dependence on manpower and improve the efficiency of conveying and transferring.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a fish conveying device on board, comprising a conveyor belt, a slide and a frozen fish hold; a plurality of baffles are arranged on both sides of the conveying surface of the conveyor belt along its own transmission direction, and at least part of the baffles are movably arranged on the conveyor belt; the feed end of the slide overlaps with the baffle of the conveyor belt where the baffle is movably arranged, and the feed end of the frozen fish hold overlaps with the discharge end of the slide.

[0005] The beneficial effect of the present invention is that baffles are added on both sides of the conveying direction of the conveyor belt to prevent the fish from sliding off the conveyor belt. At the same time, a slideway is set up to facilitate the reciprocating movement of the fish between the conveyor belt and the frozen fish tank, eliminating the need for manual handling and improving the transfer efficiency of the fish.

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0018] Please refer to Figures 1 to 4 As shown, a fish conveying device on board the present invention comprises a conveyor belt 1, a slide 2 and a frozen fish hold 3; a plurality of baffles 11 are arranged on both sides of the conveying surface of the conveyor belt 1 along its own transmission direction, and at least part of the baffles 11 are movably arranged on the conveyor belt 1; the feed end of the slide 2 overlaps with the conveyor belt 1 where the baffles 11 are movably arranged, and the feed end of the frozen fish hold 3 overlaps with the discharge end of the slide 2.

[0019] Working principle: baffles 11 are added on both sides of the conveying direction of the conveyor belt 1 to prevent the fish from sliding off the conveyor belt 1. At the same time, a slideway 2 is set up to facilitate the reciprocating movement of the fish between the conveyor belt 1 and the frozen fish tank 3, eliminating the need for manual handling and improving the transfer efficiency of the fish.

[0020] The baffle 11 on the conveyor belt 1 can be arranged with a fixed baffle 11 on one side and a movable baffle 11 on the other side; the baffles 11 at the head and tail of the conveyor belt 1 can be fixed, and the rest are movable baffles 11; the baffles 11 can be fixed on one side and the rest are movable baffles 11 except the baffles 11 at the head and tail of the other side. It is worth noting that the movable baffle 11 can be connected to the conveyor belt 1 by mortise and tenon joints, fixed to the conveyor belt 1 by pins, or hinged to the conveyor belt 1 by hinges.

[0021] In one implementation, please refer to Figure 1 and Figure 2 As shown, the feed end of the frozen fish hold 3 includes a hatch base 31 and a hatch enclosure 32 detachably arranged on the hatch base 31; when the conveyor belt 1 conveys fish to the frozen fish hold 3, the discharge end of the slide 2 overlaps with the hatch base 31, and the feed end of the slide 2 is higher than the discharge end of the slide 2. Since the feed end of the slide 2 is higher than the discharge end of the slide 2, the fish entering the feed end of the slide 2 from the conveyor belt 1 will fall into the frozen fish hold 3 along the slide 2 under the action of gravity. When the frozen fish hold 3 conveys fish to the conveyor belt 1, the hatch enclosure 32 is arranged on the hatch base 31, the discharge end of the slide 2 overlaps the hatch enclosure 32, and the feed end of the slide 2 is lower than the discharge end of the slide 2. Since the feed end of the slide 2 is lower than the discharge end of the slide 2, the fish entering the frozen fish hold 3 at the discharge end of the slide 2 will fall into the conveyor belt 1 along the slide 2 under the action of gravity.

[0022] When the fish is taken out of the frozen fish tank 3 and enters the slide 2, salt water can be injected into the frozen fish tank 3 to make the fish float out of the frozen fish tank 3 by buoyancy and then enter the slide 2. Specifically, taking frozen tuna as an example, salt water with a density of 1.040-1.050 t / m 3 of salt water.

[0023] In an optional implementation, please refer to Figure 1 and Figure 2 As shown, at least the bottom plate portion of the slide 2 is set as a grid plate so that excess water can be separated from the fish, and a water collection well 4 is set under the slide 2 to collect water, which can be reused in the cabin.

[0024] In an optional embodiment, flanges are provided on both the hatch base 31 and the hatch enclosure 32, and the hatch base 31 and the hatch enclosure 32 are connected together by bolts, thereby realizing rapid disassembly and assembly of the hatch base 31 and the hatch enclosure 32, so as to raise or lower the discharge end of the slide 2.

[0025] In an optional embodiment, the hatch enclosure 32 is made of carbon fiber reinforced plastic, which not only reduces the weight of the hatch enclosure 32 and facilitates disassembly and assembly by workers, but also the carbon fiber reinforced plastic has good salt water resistance, thereby ensuring the long-term use of the hatch enclosure 32.

[0026] In one embodiment, when the conveyor belt 1 transports fish to the frozen fish hold 3, the feed end of the slide 2 is 0.5-0.8m higher than the discharge end of the slide 2; when the frozen fish hold 3 transports fish to the conveyor belt 1, the discharge end of the slide 2 is 0.5-0.8m higher than the feed end of the slide 2.

[0027] In one embodiment, see Figure 1 and Figure 2 As shown, a guide plate 5 is provided above the conveying surface of the conveyor belt 1. The guide plate 5 is used to guide the fish to the feeding end of the slideway 2. The guide plate 5 helps to guide the fish to flow toward the slideway 2.

[0028] It is worth noting that, by setting the guide plates 5 at different heights, it is possible to screen fish of different sizes and allow them to enter the slide 2 .

[0029] In one embodiment, see Figure 3 and Figure 4 As shown, the conveyor belt 1 is a crawler conveyor, and a tensioning assembly 6 is arranged on the conveyor belt 1. The tensioning assembly 6 includes a screw rod 61, an adjusting nut 62 and a push block 63. The screw rod 61 is slidably arranged on the frame of the conveyor belt 1 along the conveying direction of the conveyor belt 1. The adjusting nut 62 is threadedly connected to the rod of the screw rod 61. The adjusting nut 62 abuts against the frame of the conveyor belt 1. The push block 63 is connected to one end of the screw rod 61. A notch 631 is arranged at the end of the push block 63 away from the screw rod 61. A clamp 12 is arranged on the driven wheel of the conveyor belt 1, and the clamp 12 is located in the notch 631. By rotating the adjusting nut 62, the amount of the push block 63 pushed out on the support of the conveyor belt 1 can be adjusted, so that the position of the driven wheel connected with the clamp 12 is changed, thereby achieving the purpose of adjusting the tension of the crawler belt of the conveyor belt 1.

[0030] In one embodiment, see Figure 4 As shown, a lap plate 7 is detachably provided at the feed end or the discharge end of the conveyor belt 1 , and the lap plate 7 is used to prevent the fish from falling off or getting stuck at the overlap of the two conveyor belts 1 .

[0031] In one embodiment, see Figure 3 and Figure 4 As shown, the frame of the conveyor belt 1 is provided with reinforcing ribs 13. The reinforcing ribs 13 can offset the adverse effects of the tensioning assembly 6, enhance the strength of the conveyor belt 1, and ensure the normal transportation of the conveyor belt 1.
