Description

Technical Field

[0001] This utility model relates to the field of fish egg collection technology, and in particular to a device for collecting adhesive fish eggs. Background Technology

[0002] Fish egg collection is an important part of aquaculture and fish reproduction. It is mainly used for artificial breeding or scientific research. By obtaining mature parent fish eggs, breeding conditions can be controlled to improve the survival rate and quality of fish fry.

[0003] Currently, fish egg collection mostly relies on manual operation, which involves squeezing the abdomen of the parent fish to expel the eggs from the genital opening. This method requires the operator to have certain experience and to use gentle and even force to squeeze the eggs into the collection container.

[0004] Manual egg retrieval requires not only restraining the parent fish to prevent struggling but also repeatedly squeezing their abdomens to fully expel the eggs. However, the parent fish's body surface is usually covered with a large amount of mucus, making it very slippery, increasing the difficulty of the operation and the risk of dropping the eggs. In addition, some fish eggs are highly adhesive and easily adhere to the operator's hands, which can lead to contamination of the eggs due to hand sweat or impurities, affecting their subsequent development. Therefore, a sticky fish egg collection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sticky fish egg collection device, which aims to improve the problem mentioned in the prior art that "manual egg collection is not only very troublesome, but also contaminates the fish eggs".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sticky fish egg collection device, including a collection box, a partition slidably connected to the inner wall of the collection box, an egg collection mechanism inside the collection box, and an auxiliary mechanism on the front of the collection box;

[0007] The egg collection mechanism includes a slide plate that runs through and slidably connects to the inner wall of the collection box. A motor is fixedly connected to the lower surface of the slide plate, and a rotating shaft is fixedly connected to the output end of the motor. A turntable is fixedly connected to the outer wall of the rotating shaft, and a rotating rod is rotatably connected to the top of the turntable. A buffer layer is fixedly connected to the outer wall of the rotating rod, and a rubber pad is fixedly connected to the outer wall of the buffer layer.

[0008] As a further description of the above technical solution:

[0009] A threaded rod is rotatably connected to the outer wall of the collection box, and a knob is fixedly connected to the end of the threaded rod away from the collection box.

[0010] As a further description of the above technical solution:

[0011] A threaded sleeve is fixedly connected to the lower surface of the slide plate, and the threaded sleeve is threadedly connected to the threaded rod.

[0012] As a further description of the above technical solution:

[0013] The auxiliary mechanism includes a scale, which is fixedly connected to the top of the data collection box.

[0014] As a further description of the above technical solution:

[0015] A connecting rod is fixedly connected to the side wall of the slide plate, and the end of the connecting rod away from the slide plate extends to the front of the collection box and is fixedly connected to a pointer.

[0016] As a further description of the above technical solution:

[0017] The rotating rods are arranged in three sets, and the three sets of rotating rods are arranged in a circular array on the top of the turntable with the rotating shaft as the central axis.

[0018] As a further description of the above technical solution:

[0019] The buffer layer is a sponge layer, which is cylindrical and wraps around the outer wall of the rotating rod.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a sticky fish egg collection device, including a collection box 1. A partition 2 is slidably connected to the inner wall of the collection box 1. When the partition 2 is pulled upward, it slides upward on the inner wall of the collection box 1, and the fish eggs stored inside the collection box 1 slide downward, thereby discharging the fish eggs inside the collection box 1. An egg collection mechanism 3 is provided inside the collection box 1. There are two sets of egg collection mechanisms 3, which are located on the left and right sides of the collection box 1, respectively. The egg collection mechanisms 3 on the left and right sides of the collection box 1 can evenly squeeze the sides of the parent fish's abdomen, causing the parent fish to expel the fish eggs. An auxiliary mechanism 4 is provided on the front of the collection box 1.

[0033] Reference Figure 2 , Figure 3 and Figure 4The egg collection mechanism 3 includes a slide plate 31, which is slidably connected to the inner wall of the collection box 1. A motor 32 is fixedly connected to the lower surface of the slide plate 31, and a rotating shaft 33 is fixedly connected to the output end of the motor 32. A turntable 34 is fixedly connected to the outer wall of the rotating shaft 33. When the motor 32 is started, it drives the rotating shaft 33 to rotate. At the same time, the rotating shaft 33 drives the turntable 34 to rotate synchronously. A rotating rod 35 is rotatably connected to the top of the turntable 34. When the turntable 34 rotates, it drives three sets of rotating rods 35 to perform circular motion around the rotating shaft 33. There are three sets of rotating rods 35, which are arranged in a circular array around the rotating shaft 33 as the central axis. At the top of the turntable 34, the eggs in the broodstock's abdomen can be squeezed out and fall into the collection box 1 by the periodic compression of three sets of rotating rods 35 in conjunction with the buffer layer 36 and the rubber pad 37. The outer wall of the rotating rod 35 is fixedly connected to the buffer layer 36, which is a sponge layer. The buffer layer 36 is cylindrical and wraps around the outer wall of the rotating rod 35. The buffer layer 36 can make soft contact with the broodstock's abdomen to avoid injury to the broodstock. The outer wall of the buffer layer 36 is fixedly connected to the rubber pad 37. The friction of the rubber pad 37 can make the buffer layer 36 squeeze the broodstock's abdomen better and prevent the buffer layer 36 from slipping.

[0034] Reference Figure 1 A threaded rod 38 is rotatably connected to the outer wall of the collection box 1. A knob 39 is fixedly connected to the end of the threaded rod 38 away from the collection box 1. A threaded sleeve 310 is fixedly connected to the lower surface of the slide plate 31. The threaded sleeve 310 is threadedly connected to the threaded rod 38. By rotating the threaded rod 38 through the knob 39, the rotation of the threaded rod 38, in conjunction with the threaded sleeve 310 that is threadedly connected to it, can drive the slide plate 31 to slide on the inner wall of the collection box 1.

[0035] Reference Figures 1-3 The auxiliary mechanism 4 includes a scale 41, which is fixedly connected to the top of the collection box 1. As the pointer 43 moves, the distance of the pointer 43 can be observed using the scale 41. At the same time, the distance between the two sets of pointers 43 can be determined using the scale 41. A connecting rod 42 is fixedly connected to the side wall of the slide plate 31. As the slide plate 31 slides on the inner wall of the collection box 1, it will drive the connecting rod 42 to move synchronously. The end of the connecting rod 42 away from the slide plate 31 extends to the front of the collection box 1 and is fixedly connected to the pointer 43. As the connecting rod 42 moves, it will drive the pointer 43 to move synchronously. By observing the distance between the two sets of pointers 43, the closest distance of the buffer layer 36 on the two sets of slide plates 31 can be determined, so as to accurately adjust the size of the slide plate 31 according to the size of the parent fish.

[0036] Working principle: Hold the parent fish to be collected and place it between two sets of sliding plates 31 so that the sides of the parent fish's abdomen can contact the rubber pads 37. Then start the motor 32 to drive the rotating shaft 33 to rotate. The rotating shaft 33 will drive the turntable 34 to rotate synchronously. The turntable 34 will drive three sets of rotating rods 35 to make circular motion around the rotating shaft 33. At the same time, the rotating rods 35 will drive the buffer layer 36 to periodically squeeze the abdomen of the parent fish. Through the periodic squeezing of the buffer layer 36 and the rubber pads 37 by the three sets of rotating rods 35, the fish eggs in the abdomen of the parent fish can be squeezed out and fall into the collection box 1.

[0037] Rotating the threaded rod 38 by the knob 39 causes the threaded sleeve 310 connected to it to slide the slide plate 31 on the inner wall of the collection box 1. This allows the distance between the two sets of slide plates 31 to be adjusted, and in turn, the distance between the buffer layer 36 above the two sets of slide plates 31 to be adjusted. This allows the position of the buffer layer 36 to be freely adjusted according to the size of the parent fish, so that the collection box 1 can collect eggs from parent fish of different sizes.

[0038] As the slide plate 31 slides on the inner wall of the collection box 1, it will drive the connecting rod 42 to move synchronously. As the connecting rod 42 moves, it will drive the pointer 43 to move synchronously. As the pointer 43 moves, the distance of the pointer 43 can be observed using the scale 41. At the same time, the distance between the two sets of pointers 43 can be determined using the scale 41. Thus, the closest distance of the buffer layer 36 on the two sets of slide plates 31 can be determined, so as to accurately adjust the size of the slide plate 31 according to the size of the parent fish.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
