Description

Technical Field

[0001] The utility model relates to the technical field of fish egg hatching, in particular to a large-scale hatching device for spinulosa barbel eggs. Background Art

[0002] The light spiny barb, also known as the spiny barb, belongs to the Cyprinidae family. Its meat is tender, sweet, nutritious, rich in protein, fat, and trace elements such as selenium and iodine, and has anti-aging and anti-cancer effects. Due to the reduction in the number of wild light spiny barb due to environmental pollution in recent years, the market prospect of artificially cultivated light spiny barb is very promising.

[0003] Farmers usually collect the eggs laid by the light-spined barb, hatch them using hatchery equipment, cultivate small fry, and then release them into the wild or continue to cultivate them.

[0004] However, the prior art has the following defects:

[0005] When the eggs of the spiny barb are placed in the hatching pond for hatching, the eggs are placed in the filter screen for subsequent removal after hatching. However, the hatching pond is generally large, and in order to ensure that the eggs can be stably exposed to the sun and absorb nutrients, the eggs are generally placed in the middle of the hatching pond. In this way, when removing the eggs, you need to find tools to salvage the filter screen in the middle of the hatching pond to the side of the hatching pond for collection. This results in the collection of fish eggs being limited and the filter screen is unstable during salvage, and it is likely to tip over. Utility Model Content

[0006] In order to solve the technical problem that the fish eggs in the middle of the hatching pond are easily dumped due to environmental restrictions or unstable force when being salvaged, the utility model provides a large-scale hatching device for the eggs of spiny barb.

[0007] The utility model adopts the following technical scheme to achieve: a large-scale hatching device for spiny barbel eggs.

[0008] It comprises an incubation pool, an air pump is placed at the bottom of the incubation pool, a filter plate is laid on the air pump, and a filter box is placed on the filter plate;

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] Embodiment 1:

[0034] Please combine Figure 1-7 The present embodiment is a large-scale hatching device for spiny barb roe, comprising a hatching pool 1, an air pump 2 is placed at the bottom of the hatching pool 1, a filter plate 3 is laid on the air pump 2, and a filter box 4 is placed on the filter plate 3;

[0035] The mobile winding mechanism includes a connecting rod 6, a mobile winding unit and a supporting unit. One end of the connecting rod 6 is hinged to one end of a support rod 5, and the other end of the support rod 5 is fixed to one end of the incubation tank 1. The other end of the connecting rod 6 is arranged at the other end of the incubation tank 1 through the supporting unit. The connecting rod 6 is provided with a mobile winding unit to drive the filter box 4 to gradually move away from the filter plate 3.

[0036] The mobile winding mechanism includes a rack plate 7, a rotating rod 11, a winding wheel 12, a gear 13, a rope 14 and a sliding unit. The two rack plates 7 are fixed on the connecting rod 6. The rack plate 7 and the gear 13 constitute an engaging connection structure. The middle part of the rotating rod 11 is fixed to the middle part of the two gears 13, and the two winding wheels 12 are fixed to the two ends of the rotating rod 11. One end of the rope 14 is fixed on the winding wheel 12, and the other end of the rope 14 is fixed on the filter box 4.

[0037] The sliding unit includes a fixed plate 8, a slider 9 and a slide rail 10. One end of the fixed plate 8 is fixed on the connecting rod 6 and is located between the two rack plates 7. One end of the slider 9 is fixed to the other end of the fixed plate 8. The slide rail 10 is opened on the rotating rod 11, and the slider 9 contacts inside the slide rail 10.

[0038] The implementation principle of the large-scale hatching device for barb bream eggs of the present application is as follows: when the filter box 4 is moved out of the hatching pool 1, the end of the support rod 21 away from the hatching pool 1 is rotated to separate the magnet 1 22 and the magnet 2 23. As the support rod 21 rotates, the hinged outer rod 17 and the hinged inner rod 16 are also rotated, and the moving block 19 slides on the slide 20, the hinged inner rod 16 moves out from the inside of the hinged outer rod 17, and the spring 18 is stretched. Because the connecting rod 6 loses the vertical support force of the hinged inner rod 16 and the hinged outer rod 17, the end close to the support rod 21 will gradually tilt, causing the connecting rod 6 to tilt, and the gear 13 falls to the support rod 21 under the action of gravitational potential energy. Under the meshing connection of the rack plate 7 and the gear 13, the gear 13 rotates while approaching the second support rod 21. Since the rotating rod 11 rotates together with the gear 13, the slide rail 10 is driven to slide on the slider 9. The winding wheel 12 rotates and the rope 14 is wound, thereby driving the filter box 4 to approach the connecting rod 6. In this process, the filter box 4 gradually moves closer to the connecting rod 6 and gradually moves to one side of the incubator 1. When the hinged inner rod 16 and the hinged outer rod 17 are separated to the maximum elastic potential energy of the spring 18, the connecting rod 6 and the second support rod 21 are stationary. At this time, since the filter box 4 is attached to the inner wall of the incubator 1 (located at Figure 3 The position of B in the middle) at this moment, the gear 13 stops rotating on the rack plate 7, and the fish eggs that can be hatched in the filter box 4 can be removed by standing on the position of the support rod 21. After the fish eggs in the filter box 4 are removed, the support rod 21 is gradually rotated to a vertical state, so that the magnet 23 and the magnet 1 22 are adsorbed again, so that the hinged inner rod 16 continues to move in the hinged outer rod 17, and the hinged outer rod 17 is restored, so that the hinged inner rod 16 and the hinged outer rod 17 continue to be in a vertical state, and the movable groove 15 above the hinged inner rod 16 is lifted up at this moment, so that the connecting rod 6 is tilted again, and the rope belt 14 is driven back to the original position.
