Technical Field

[0001] This utility model relates to the field of fish farming technology, and in particular to a layered fish fry incubator with adjustable light angle. Background Technology

[0002] Hatching boxes are mainly used for hatching eggs, embryo development, and in poultry hatching in farms, hatcheries, and chicken farms. They are also widely used in the fish farming industry.

[0003] For example, Chinese utility model patent application number CN202120405226.5, entitled "A Layered Fish Fry Hatching Box with Adjustable Illumination Angle," includes a main box, a base, a frying box, and a hatching light panel. The lower end of the main box is fixedly connected to the upper end of the base. The frying box is located inside the main box. A control panel is located on the left outer wall of the main box. Racks are located on both the left and right sides below the frying box, and rollers are located on both the left and right sides of the frying box. The hatching light panel is located at the upper end inside the frying box. A working gear is located at the lower end of the racks. A working motor is located on the right inner wall of the main box. A long shaft is located in the middle of the working gear. The drive shaft of the working motor is fixedly connected to the right end of the long shaft via a connecting key. This device can adjust the illumination angle inside the hatching box and features an automatically moving frying box. However, the hatching light panel is in a straight line shape, which means that the illumination angle can only be adjusted within a small range after the hatching light panel rotates.

[0004] Therefore, there is an urgent need for a layered fish fry incubator with adjustable lighting angle to solve the problem that the existing technology, due to the linear shape of the incubator light panel, can only adjust the lighting angle within a small range after the panel is rotated, resulting in inconvenience in use. Utility Model Content

[0005] In view of this, it is necessary to provide a layered fish fry incubator with adjustable light angle to solve the technical problem in the prior art where the incubator light panel is in a straight line, which means that the light angle can only be adjusted within a small range after the incubator light panel is rotated, thus making it inconvenient to use.

[0006] To achieve the above technical objectives, the present invention provides a layered fish fry incubation box with adjustable light angle, comprising:

[0007] The container has at least one incubation tank.

The fixed end of the driving part is connected to the large diameter end of the rotating shaft, and the movable end is connected to one of the crown gears, for driving the two crown gears to mesh with each other and causing the two illumination plates to rotate relative to the small diameter section of the rotating shaft.

[0012] Furthermore, the circumferential sidewall of the small-diameter end of the rotating shaft is provided with at least one spherical groove relative to the crown gear, and the driving member also includes at least one rolling part, the rolling part being provided in a one-to-one correspondence with the spherical groove, the rolling part being rotatably embedded in the spherical groove and abutting against the crown gear.

[0013] Furthermore, the drive unit includes an outer gear sleeve, a first transmission gear, and a first drive motor. The outer gear sleeve is fixedly sleeved on one of the crown gears. The first transmission gear meshes with the outer gear sleeve. The fixed end of the first drive motor is connected to the large-diameter end of the rotating shaft, and the output shaft is coaxially connected to the first transmission gear. The motor is used to drive the first transmission gear to mesh with the outer gear sleeve, so that the two crown gears mesh.

[0014] Furthermore, the number of incubation troughs in the box is two, and the two incubation troughs are spaced apart along the height direction of the box. The incubation drawer is arranged in a one-to-one correspondence with the incubation trough and can be slidably inserted into the incubation trough.

[0015] Furthermore, the rotating component also includes a second transmission gear, which is built into the receiving groove and fixedly sleeved on the small diameter section of the rotating shaft. The adjustable light angle layered fish fry incubation box also includes a first drive assembly, which includes a sliding rack and a linear drive unit. The sliding rack is slidably connected to the inner wall of the receiving groove along the height direction of the box body, and both of the second transmission gears can mesh with the sliding rack. The linear drive unit has a fixed end and an extended end. The fixed end of the linear drive unit is connected to the receiving groove, and the extended end is connected to the sliding rack, for driving the sliding rack to slide relative to the box body, so that the second transmission gear and the rotating shaft rotate around their own rotation axis.

It is used to drive the incubation drawer and the sliding block to slide relative to the box body along the guide of the slide groove.

[0018] Furthermore, the second drive assembly includes two fixed racks, a connecting shaft, two drive gears, and a second drive motor. The two fixed racks are parallel to each other and spaced apart, and are fixedly connected to the inner wall of the incubation tank.

The drive gears are arranged one-to-one with the fixed racks and are fixedly sleeved on the connecting shaft. The fixed end of the second drive motor is connected to the housing, and the output shaft is coaxial with the connecting shaft. It is used to drive the two drive gears to mesh with the two fixed racks respectively, so that the incubation tray and the sliding block slide relative to the housing along the guide of the slide groove.

Driven by a driving component, the two light plates can rotate relative to the rotating component to adjust the size of the light angle. Compared with the prior art, by setting two light plates that can rotate relative to the rotating component to form a light angle, after the rotating component rotates the two light plates for a first-stage rotation, they can each achieve a second-stage rotation relative to the rotating component under the drive of the driving component. This increases the adjustment range of the light angle formed by the light plates, making it convenient to use and suitable for different scenarios. It solves the technical problem in the prior art where the incubation light plate is in a straight line shape, which limits the adjustment of the light angle to a small range after rotation, resulting in inconvenience in use.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] Please see Figures 1 to 3 This utility model provides a layered fish fry incubation box with adjustable light angle, including: a box body 100, at least one incubation drawer 200 and at least one lighting component 300. The box body 100 has at least one incubation trough 110. The incubation drawer 200 is slidably inserted into the incubation trough 110. The lighting component 300 includes a rotating member 310, two lighting plates 320 and a driving member 330. The rotating member 310 is rotatably connected to the top inner wall of the incubation trough 110. The two lighting plates 320 are respectively arranged relative to the incubation drawer 200 and are rotatably connected to both sides of the rotating member 310. A light angle 321 is formed between the two lighting plates 320. The driving member 330 is connected to both lighting plates 320 and is used to drive the two lighting plates 320 to rotate relative to the rotating member 310 to adjust the size of the light angle 321.

[0029] In this device, at least one incubation trough 110 is provided inside the box 100. An incubation drawer 200 is set relative to the incubation trough 110 and can be slidably inserted into the incubation drawer 200. Two light plates 320 are rotatably connected to the top inner wall of the incubation trough 110 via a rotating member 310. A light angle 321 is formed between the two light plates 320. Under the drive of the driving member 330, the two light plates 320 can rotate relative to the rotating member 310 respectively to adjust the size of the light angle.

[0030] Compared to existing technologies, by setting two light-emitting plates 320 that can rotate relative to the rotating member 310 to form a light angle, the rotating member 310, after rotating the two light-emitting plates 320 for a first-stage rotation, can achieve a second-stage rotation relative to the rotating member 310 under the drive of the driving member 330. This increases the adjustment range of the light angle formed by the light-emitting plates 320, making it convenient to use and suitable for different scenarios. It can solve the technical problem in existing technologies where the incubation light panel is in a straight line, which means that the light angle can only be adjusted within a small range after the incubation light panel is rotated, resulting in inconvenience in use.

[0031] Furthermore, the hatching tray 200 in this device is equipped with a temperature sensor and a pressure sensor. The hatching tray 200 is filled with water, and the fish fry are placed in the hatching tray 200 for hatching. The temperature sensor and pressure sensor are used to detect the temperature and pressure of the water. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0032] In this embodiment, as Figure 1 , Figure 2As shown, the adjustable light angle layered fish fry incubator also includes multiple sliding blocks 400, a first drive assembly 500, and a second drive assembly 600. The rotating component 310 includes a rotating shaft 311 and a second transmission gear 312. The drive component 330 includes two crown gears 331 and a drive part 332, and at least one rolling part 333.

[0033] The incubation tank 110 has sliding grooves on its two opposite side walls, and sliding blocks 400 are set in correspondence with the sliding grooves. One end of the sliding block 400 is slidably embedded in the sliding groove, and the other end is connected to the side wall of the incubation tray 200.

[0034] The incubator 200 is slidably connected to the box 100 via sliding blocks 400 on both sides, with the sliding blocks 400 serving as support and connection.

[0035] One implementation method is, for example Figure 1 , Figure 2 As shown, there are two incubation troughs 110 in the box 100. The two incubation troughs 110 are arranged at intervals along the height direction of the box 100. The incubation drawer 200 is arranged in a one-to-one correspondence with the incubation trough 110 and can be slidably inserted into the incubation trough 110.

[0036] By arranging the incubation tanks 110 at intervals along the height direction, layered management can be achieved, which facilitates production.

[0037] One implementation method is, for example Figure 2 As shown, the box 100 is also provided with a receiving groove 120 and at least one rotating hole. The rotating hole is connected to both the receiving groove 120 and the incubation tank 110. The rotating shaft 311 has a large diameter section and a small diameter end. The small diameter end of the rotating shaft 311 is inserted into the rotating hole and built into the receiving groove 120. The large diameter section of the rotating shaft 311 is built into the incubation tank 110, and the two light plates 320 are respectively rotatably connected to the large diameter section of the rotating shaft 311.

[0038] The rotating shaft 311 is rotatably inserted into the rotating hole, which supports and connects the two illumination plates 320.

[0039] Furthermore, the illumination plate 320 here is a common and readily available device on the market. The two illumination plates 320 are respectively set on both sides of the rotating shaft 311. By driving the two illumination plates 320 to rotate relative to the rotating shaft 311, the illumination angle can be adjusted. This will not be elaborated further here.

[0040] One implementation method is, for example Figure 3 , Figure 4As shown, two crown gears 331 mesh with each other and are rotatably mounted on the small diameter section of the rotating shaft 311. The illumination plate 320 is arranged in a one-to-one correspondence with the crown gears 331. The two illumination plates 320 are arranged on both sides of the rotating shaft 311 and are respectively connected to the two crown gears 331. The drive unit 332 has a fixed end and a movable end. The fixed end of the drive unit 332 is connected to the large diameter end of the rotating shaft 311, and the movable end is connected to a crown gear 331. It is used to drive the two crown gears 331 to mesh with each other and to make the two illumination plates 320 rotate relative to the small diameter section of the rotating shaft 311.

[0041] Both illumination plates 320 are rotatably mounted on the rotating shaft 311 via crown gears 331, achieving a rotatable connection. The two crown gears 331 can mesh with each other, and driving one crown gear 331 to rotate can realize the transmission of the other crown gear 331, so that the illumination angle 321 is adjusted accordingly.

[0042] Furthermore, the crown gear 331 here is a common and readily available piece of equipment on the market, and is a conventional setup known to those skilled in the art, so it will not be described in detail here.

[0043] As another implementation method, such as Figure 3 As shown, the circumferential sidewall of the small diameter end of the rotating shaft 311 is provided with at least one spherical groove relative to the crown gear 331. The rolling part 333 is provided in correspondence with the spherical groove. The rolling part 333 is rotatably embedded in the spherical groove and abuts against the crown gear 331.

[0044] The rolling part 333 is disposed between the rotating shaft 311 and the crown gear 331 and abuts against both of them, in order to reduce the friction between the rotating shaft 311 and the crown gear 331 and improve the stability of the device.

[0045] In this embodiment, the drive unit 332 includes an outer gear sleeve 3321, a first transmission gear 3322, and a first drive motor 3323. The outer gear sleeve 3321 is fixedly sleeved on a crown gear 331. The first transmission gear 3322 meshes with the outer gear sleeve 3321. The fixed end of the first drive motor 3323 is connected to the large diameter end of the rotating shaft 311, and the output shaft is coaxially connected to the first transmission gear 3322. It is used to drive the first transmission gear 3322 to mesh with the outer gear sleeve 3321, so that the two crown gears 331 mesh.

[0046] The outer gear sleeve 3321 is fixedly sleeved on a crown gear 331 and meshes with the first transmission gear 3322. Driven by the output shaft of the first drive motor 3323, the outer gear sleeve 3321 continuously meshes with the first transmission gear 3322, so that the two crown gears 331 mesh with each other and the two illumination plates 320 rotate closer or further away from each other, thereby adjusting the size of the illumination angle 321 and increasing the adjustment range.

[0047] Furthermore, the first drive motor 3323 here is a common and readily available forward and reverse motor on the market, which has a self-locking function and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0048] As another implementation method, such as Figures 3 to 5 As shown, the second transmission gear 312 is built into the receiving groove 120 and fixedly sleeved on the small diameter section of the rotating shaft 311. The layered fish fry incubation box with adjustable light angle also includes a first drive assembly 500. The first drive assembly 500 includes a sliding rack 510 and a linear drive part 520. The sliding rack 510 is slidably connected to the inner wall of the receiving groove 120 along the height direction of the box body 100, and both second transmission gears 312 can mesh with the sliding rack 510. The linear drive part 520 has a fixed end and an extended end. The fixed end of the linear drive part 520 is connected to the receiving groove 120, and the extended end is connected to the sliding rack 510. It is used to drive the sliding rack 510 to slide relative to the box body 100, so that the second transmission gear 312 and the rotating shaft 311 rotate around their own rotating shaft 311.

[0049] Both rotating shafts 311 are connected to the linear drive unit 520 through the meshing of the second transmission gear 312 and the rack. The extension end of the linear drive unit 520 can extend or shorten relative to its fixed end, which can drive the two second transmission gears 312 and the two rotating shafts 311 to rotate in the forward or reverse direction around their rotation axis 311 line, thereby causing the rotating shaft 311 and the two illumination plates 320 to deflect as a whole.

[0050] Furthermore, the overall deflection of the rotating shaft 311 and the two illumination plates 320 is a first-level adjustment, and the rotation of the two illumination plates 320 relative to the rotating shaft 311 is a second-level adjustment. Through the first-level and second-level adjustments, the angle adjustment range of the illumination plates 320 can be increased.

[0051] In this embodiment, as Figure 2 As shown, the second drive assembly 600 has a fixed end and a movable end. The fixed end of the second drive assembly 600 is connected to the inner wall of the incubation tank 110, and the movable end is connected to the incubation drawer 200. It is used to drive the incubation drawer 200 and the sliding block 400 to slide relative to the box 100 along the guide of the slide groove.

[0052] The sliding of the movable end of the second drive component 600 relative to its fixed end can cause the incubation tray 200 to slide relative to the box 100, so that the incubation tray 200 can be inserted into the incubation tank 110 or pulled out of the incubation tray 200, which facilitates incubation operation and production management.

[0053] One implementation method is, for example Figure 2 As shown, the second drive assembly 600 includes two fixed racks 610, a connecting shaft 620, two drive gears 630, and a second drive motor 640. The two fixed racks 610 are parallel to each other and spaced apart, and are fixedly connected to the inner wall of the incubation tank 110. The connecting shaft 620 is connected to the bottom of the incubation tray 200 and can rotate relative to the incubation tray 200. The drive gears 630 are arranged one-to-one with the fixed racks 610 and are fixedly sleeved on the connecting shaft 620. The fixed end of the second drive motor 640 is connected to the housing 100, and the output shaft is coaxial with the connecting shaft 620. It is used to drive the two drive gears 630 to mesh with the two fixed racks 610 respectively, so that the incubation tray 200 and the sliding block 400 slide relative to the housing 100 along the guide groove.

[0054] The second drive motor 640 drives two drive gears 630 to mesh with two fixed racks 610 respectively, which can generate a push and push the incubation tray 200 to slide relative to the box 100.

[0055] Furthermore, the second drive motor 640 here is a common and readily available forward and reverse motor with a self-locking function, which is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0056] The specific workflow of this utility model is as follows: At least one incubation trough 110 is provided inside the housing 100. An incubation drawer 200 is positioned relative to the incubation trough 110 and can be slidably inserted into the incubation drawer 200. Two illumination plates 320 are rotatably connected to the top inner wall of the incubation trough 110 via a rotating member 310. A light angle 321 is formed between the two illumination plates 320. Driven by a driving member 330, the two illumination plates 320 can rotate relative to the rotating member 310 respectively to adjust the size of the light angle. Compared to existing technologies, by setting two illumination plates 320 that can rotate relative to the rotating member 310 to form a light angle, the rotating member 310, after rotating the two illumination plates 320 for a first-stage rotation, can achieve a second-stage rotation relative to the rotating member 310 under the drive of the driving member 330. This increases the adjustment range of the light angle formed by the illumination plates 320, making it convenient to use and suitable for different scenarios.

[0057] In use, the user first places the fish fry to be hatched into the hatching tray 200. Controlling the output shaft of the second drive motor 640 to rotate enables the hatching tray 200 to be inserted into the hatching tank 110. Next, when it is necessary to adjust the light angle, the extended end of the drive linear drive unit 520 is extended or shortened relative to its fixed end, causing the rotating shaft 311 and the two light plates 320 to rotate relative to the box 100. Then, when it is necessary to adjust the light angle 321, the output shaft of the first drive motor 3323 drives the first transmission gear 3322 to mesh with the outer gear sleeve 3321. The two rotating crown gears 331 mesh with each other, causing the two light plates 320 to rotate relative to the rotating shaft 311 respectively. Finally, the water temperature is detected by a temperature sensor. When the water temperature reaches the preset temperature, the light plates 320 stop working.

[0058] This device, through the aforementioned structure, can solve the technical problem in the prior art where the incubation lamp panel is in a straight line shape, which means that the light angle can only be adjusted within a small range after the incubation lamp panel is rotated, thus causing inconvenience in use.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
