Technical Field
[0001] The utility model relates to the technical field of fry hatching, and more specifically, to a fish fry hatching device. Background Art
[0002] In recent years, with the continuous development of the aquaculture industry, the demand for fry has been increasing, and the demand for artificial hatching of fish eggs has also been increasing. The success of artificial reproduction, in addition to broodstock cultivation and timely induced spawning, the hatching equipment for fry is one of the important links to improve the hatching rate of fish eggs. Nowadays, the use of fry incubators is becoming more and more common.
[0003] Currently, when hatching fry, it is first necessary to place the fertilized fish eggs in the hatching pond, and the hatching process of the fry is completed through the hatching pond. During the hatching process of the fry, it is necessary to continuously supply oxygen into the hatching pond. Since the fish eggs are relatively fragile, the traditional oxygen supply machine will drive the water flow to generate violent fluctuations, and the fish eggs are easily damaged by the impact, resulting in a reduction in the hatching success rate of the fish eggs. In view of this, we propose a fish fry hatching device. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a fish fry hatching device to solve the technical problem that the current traditional oxygen supply machine will drive the water flow to generate violent fluctuations, and the fish eggs are easily damaged by the impact, resulting in a reduction in the hatching success rate of the fish eggs.
[0005] To solve the above technical problems, the utility model provides the following technical solutions: A fish fry hatching device includes a hatching component with water-turning components symmetrically and movably installed at the top.
[0006] The hatching component includes a hatching pond with an end face gear disc fixedly installed at the top, and meshing teeth are formed in an annular array on the surface of the end face gear disc.
[0007] The water-turning component includes a U-shaped mounting seat, a motor is detachably installed on one side of the U-shaped mounting seat, the motor is connected to a bevel gear rotatably installed inside the U-shaped mounting seat through a motor shaft, the bevel gear is movably meshed with the meshing teeth, and one end of the bevel gear is coaxially and fixedly connected to a rotating shaft rotatably passing through the U-shaped mounting seat. A coupling sleeve is rotatably connected between the rotating shafts of the symmetrically arranged water-turning components, and water-turning structures are arranged in an annular array on the outer edge surface of the rotating shaft.
[0008] The utility model designs a bevel gear that meshes with the meshing teeth movably. By starting the motor, the motor shaft of the motor drives the bevel gear to rotate. Under the movable meshing of the bevel gear and the meshing teeth, it rolls on the surface of the end face gear disc. While the bevel gear rotates, it drives the rotating shaft to rotate, so that the water turning structure drives the water surface inside the hatching pool to fluctuate, thereby promoting the integration of oxygen into the water to form dissolved oxygen. Compared with traditional oxygen supply machines, it is not easy to cause violent fluctuations in the water flow, thereby reducing the breakage rate of fish eggs and improving the hatching success rate of fish eggs. And because the water turning components are symmetrically arranged and connected by a coupling sleeve, the rotating shafts in the symmetrically arranged water turning components are in opposite movement states, so the irregularity of the water surface fluctuation when the water turning structure in the water turning component contacts the water surface is improved, avoiding the situation of water splashing caused by the superposition of regular fluctuations of the water surface.
[0009] Preferably, the water turning structure includes spiral water turning blades arranged on the outer edge surface of the rotating shaft, and the spiral water turning blades are fixedly connected to the outer edge surface of the rotating shaft.
[0010] Preferably, a vertical plate is centrally connected to the bottom of one side of the U-shaped mounting seat, and a positioning abutting plate is connected to the bottom end of the vertical plate. The positioning abutting plate is movably abutted against the bottom of the end face gear disc.
[0011] Preferably, a fixing block is connected to the bottom of the other side of the U-shaped mounting seat, and a connecting shaft is rotatably installed inside the fixing block.
[0012] Preferably, a limiting plate is connected to the bottom end of the connecting shaft, and a positioning roller is rotatably installed on the outer edge surface of the connecting shaft. The outer edge surface of the positioning roller is in rolling abutment with the outer edge surface of the hatching pool.
[0013] Preferably, heightening support plates are arranged in an annular array at the edge position of the lower end face of the hatching pool, and the heightening support plates are connected to the bottom end of the hatching pool.
[0014] Compared with the prior art, the beneficial effects of the utility model are:
[0015] 1. The utility model designs a bevel gear that meshes with the meshing teeth movably. By starting the motor, the motor shaft of the motor drives the bevel gear to rotate. Under the movable meshing of the bevel gear and the meshing teeth, it rolls on the surface of the end face gear disc. While the bevel gear rotates, it drives the rotating shaft to rotate, so that the water turning structure drives the water surface inside the hatching pond to fluctuate, thereby promoting the integration of oxygen into the water to form dissolved oxygen. Compared with traditional oxygen supply machines, it is not easy to cause violent fluctuations in the water flow, thereby reducing the breakage rate of fish eggs and improving the hatching success rate of fish eggs. And because the water turning components are symmetrically arranged and connected through a coupling sleeve, the rotating shafts in the symmetrically arranged water turning components are in opposite movement states. Therefore, the irregularity of the water surface fluctuation when the water turning structure in the water turning component contacts the water surface is improved, avoiding the situation that the regular fluctuations of the water surface are superimposed and causing the water flow to splash out, solving the problem that traditional oxygen supply machines drive the water flow to produce violent fluctuations, and fish eggs are easily damaged by impact, resulting in a reduction in the hatching success rate of fish eggs.
[0016] 2. The utility model also designs spiral water turning blades. The spiral structure of the spiral water turning blades enables them to continuously contact the water surface from one end to the other when contacting the water surface. Compared with the traditional straight plate structure, it is beneficial to reduce the contact area at the same time, thereby avoiding driving the water surface to produce violent fluctuations during rotation. And the spiral structure of the spiral water turning blades can bring up part of the water flow to break away from the water surface and flow back when rotating and contacting the water surface, further promoting the integration of dissolved oxygen, thereby improving the oxygen supply effect.

The hatching assembly 1 includes a hatching pool 101 with an end face gear disc 103 fixedly installed at the top. The surface of the end face gear disc 103 is formed with meshing teeth 104 in an annular array structure. The water-turning assembly 2 includes a U-shaped mounting seat 201. A motor 206 is detachably installed on one side of the U-shaped mounting seat 201. The motor 206 is connected by a motor shaft to a bevel gear 207 rotatably installed inside the U-shaped mounting seat 201. The bevel gear 207 is movably meshed with the meshing teeth 104, and one end of the bevel gear 207 is coaxially and fixedly connected to a rotating shaft 208 that can rotate out of the U-shaped mounting seat 201. A coupling sleeve 3 is rotatably connected between the rotating shafts 208 of the symmetrically arranged water-turning assemblies 2. The outer edge surface of the rotating shaft 208 is provided with a water-turning structure in an annular array.
[0024] In an embodiment of the present utility model, the water-turning structure includes spiral water-turning blades 209 provided on the outer edge surface of the rotating shaft 208, and the spiral water-turning blades 209 are fixedly connected to the outer edge surface of the rotating shaft 208.
[0025] In an embodiment of the present utility model, a vertical plate 210 is centrally connected to the bottom of one side of the U-shaped mounting seat 201. The bottom end of the vertical plate 210 is connected to a positioning abutting plate 211, and the positioning abutting plate 211 is movably abutted against the bottom of the end face gear disc 103. A fixing block 202 is connected to the bottom of the other side of the U-shaped mounting seat 201. A connecting shaft 203 is rotatably installed inside the fixing block 202. The bottom end of the connecting shaft 203 is connected to a limiting plate 205, and a positioning roller 204 is rotatably installed on the outer edge surface of the connecting shaft 203. The outer edge surface of the positioning roller 204 is in rolling abutment with the outer edge surface of the hatching pool 101.
[0026] In an embodiment of the present utility model, a raised support plate 102 is arranged in an annular array at the edge position of the lower end face of the hatching pool 101, and the raised support plate 102 is connected to the bottom end of the hatching pool 101.
[0027] Working principle: This embodiment provides a fish fry hatching device. When in use, the motor 206 can be started, and the motor shaft of the motor 206 drives the bevel gear 207 to rotate. Under the active engagement of the bevel gear 207 and the meshing teeth 104, it rolls on the surface of the face gear disc 103. While the bevel gear 207 rotates, it drives the rotating shaft 208 to rotate, so that the spiral water-turning blade 209 drives the water surface inside the hatching pond 101 to fluctuate, thereby promoting the integration of oxygen into the water to form dissolved oxygen. Since the water-turning components 2 are symmetrically arranged and connected by the coupling sleeve 3, the rotating shafts 208 in the symmetrically arranged water-turning components 2 are in opposite motion states. Therefore, the water-turning structure in the water-turning component 2 is improved in terms of the irregularity of the water surface fluctuation when contacting the water surface, avoiding the situation of water splashing caused by the superposition of regular water surface fluctuations. The spiral structure of the spiral water-turning blade 209 enables it to continuously contact the water surface from one end to the other when contacting the water surface. Compared with the traditional straight plate structure, it is beneficial to reduce the contact area at the same time, thereby avoiding driving the water surface to generate violent fluctuations during rotation. Moreover, the spiral structure of the spiral water-turning blade 209 can bring up part of the water flow to break away from the water surface and flow back when rotating and contacting the water surface, further promoting the integration of dissolved oxygen. When the bevel gear 207 rolls on the surface of the face gear disc 103, positioning is achieved through the active abutment of the positioning abutting plate 211 at the bottom of the face gear disc 103, and the stability of the water-turning component 2 during operation is improved by the rolling of the positioning roller 204 on the outer edge surface of the hatching pond 101.
