Description

Technical Field

[0001] This invention relates to the field of incubation equipment technology, specifically to a 54-incubation tray. Background Technology

[0002] Incubation refers to the process of artificially simulating conditions such as temperature, humidity, and egg turning in oviparous animals, allowing fertilized eggs (hatching eggs) to develop into life over a certain period of time. Incubation technology is used in breeding farms, hatcheries, biotechnology company incubation laboratories, school incubation laboratories, and so on.

[0003] Hatcheries typically incubate eggs in large batches. This requires placing the eggs in incubation trays, then placing the trays on an incubation cart, and finally pushing the cart into the incubator. The system controls the creation of a suitable incubation environment within the incubator, including temperature, humidity, ventilation, egg turning, and sterilization, ultimately achieving mass incubation. Therefore, the incubation trays must not only have sufficient strength and breathability but also a structure that allows for large-angle turning of the eggs, especially goose eggs. Turning the eggs is crucial for ensuring normal embryonic development. If the eggs are not turned during incubation or the turning angle is insufficient, the embryo mortality rate will increase, and the hatchability will decrease. Turning also helps guide and regulate airflow within the incubator and helps prevent high temperatures. Therefore, the structure of the incubation trays directly affects the incubation results.

[0004] Most existing incubation trays suffer from poor air permeability, poor compatibility, and a tendency for the larger end of the egg to face downwards when flipped at a large angle. Therefore, further improvements are needed. For example, Chinese patent CN217336989U discloses an egg tray for incubators with good air permeability, allowing eggs to slide smoothly when flipped at a large angle, and offering some compatibility with eggs of different weights. However, this egg tray has significant drawbacks. For instance, eggs weighing less than 130g are slender, and the smaller end of the egg can easily leak out of the holding unit, with its lowest point below the fixing frame. This can easily cause bumps and damage to the smaller end of small-weight eggs when placing them on the tray. Secondly, flipping the eggs at a large angle during incubation can cause the smaller end to face upwards, potentially leading to malposition and increasing the stillbirth rate.

[0005] To address the aforementioned issues, we propose a method using 54 incubation trays. Summary of the Invention

[0006] To address the problems in the background art, the present invention provides a 54-incubation disc.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A 54-piece incubation tray includes an incubation tray in the shape of a cuboid with rounded corners, consisting of an outer frame, reinforcing ribs, corner supports, and an egg-holding area. The egg-holding area includes short ribs, long ribs, crossbeams, horizontal supports, vertical supports, and rounded corner ribs. The short ribs and long ribs are of the same height and are installed flush with each other, with their bottom edges higher than the bottom of the outer frame. The short ribs and long ribs are evenly distributed vertically in a grid pattern, dividing the inner cavity of the outer frame into 54 egg-holding areas.

[0008] Preferably, the reinforcing rib is located at the symmetrical center of the incubation tray, with its bottom flush with the outer frame and its top lower than the outer frame.

[0009] Preferably, the support corners are located at the four corners of the outer frame, the support corners are higher than the outer frame, the support corners are shaped like a frustum, and the top is provided with a boss.

[0010] Preferably, the crossbeam is located at the bottom inside the egg-holding area. The crossbeam is narrow in the middle and wide at both sides. The bottom of the crossbeam is flush with the bottom of the short ribs, and both ends are connected to the long ribs. Its edges have rounded corners.

[0011] Preferably, the cross braces are arranged on both sides of the inner cavity of the egg-holding area and are fixedly connected to the side of the long rib. The two sets of cross braces are symmetrical to each other and are located diagonally above the crossbeam.

[0012] Preferably, the vertical supports are set on the top of the long ribs, and two vertical supports are set on the top of the long ribs on both sides of each egg-holding area. The height of the vertical supports is flush with the reinforcing ribs.

[0013] Preferably, the rounded corner rib is located at the junction of the short rib, the long rib, and the outer frame, forming a rounded transition connection.

[0014] Preferably, the outer frame is designed with rectangular ventilation holes on all four sides, and the ventilation holes are symmetrically distributed in structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The incubation tray of this invention is a rectangular prism with rounded corners, consisting of an outer frame, reinforcing ribs, corner supports, and egg-holding areas, with a total of 54 egg-holding areas. This incubation tray has the advantages of simple structure, good air permeability, and strong compatibility. While ensuring the reliability and safety of the overall structure, it can also achieve large-angle egg-turning movements of hatching eggs of different sizes ranging from 110 to 200g during the incubation process, thereby effectively improving the hatching rate of embryos. In addition, the stepped protrusions at the bottom ventilation area of ​​the outer frame and the corner supports increase the safe distance between the upper and lower incubation trays, preventing eggs from being squeezed in the same position on the upper and lower trays. Therefore, the incubation trays can be transported with eggs, further improving the convenience of use. Attached Figure Description

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 5 As shown, this embodiment of a 54-packet incubation tray includes an incubation tray that is generally rectangular with rounded corners, consisting of an outer frame 1, reinforcing ribs 3, corner supports 4, and egg-holding areas 2. The egg-holding areas 2 include short ribs 7, long ribs 8, crossbeams 9, horizontal supports 10, vertical supports 11, and rounded corner ribs 12. The short ribs 7 and long ribs 8 are of the same height, installed flush vertically, and their bottom edges are higher than the bottom of the outer frame 1. The short ribs 7 and long ribs 8 are evenly distributed vertically in a grid pattern, dividing the inner cavity of the outer frame 1 into 54 egg-holding areas 2. The specifications of the egg-holding areas 2 are as follows: type.

[0019] Among them, the reinforcing rib 3 is located at the symmetrical center of the incubation tray, with its bottom flush with the outer frame 1 and its top lower than the outer frame 1; the support corner 4 is set at the four corners of the outer frame 1, the support corner 4 is higher than the outer frame 1, its shape is a frustum, and a boss 5 is provided on the top. The boss 5 can be inserted into the conical hole at the bottom of the support corner 4, so that the incubation trays can be stacked and arranged.

[0020] The crossbeam 9 is located at the bottom of the inner side of the egg-holding area 2. The crossbeam 9 is narrow in the middle and wide at both sides. The bottom of the crossbeam 9 is flush with the bottom of the short rib 7, and both ends are connected to the long rib 8. Its edges have rounded corners. The cross braces 10 are set on both sides of the inner cavity of the egg-holding area 2 and are fixedly connected to the sides of the long rib 8. The two sets of cross braces 10 are symmetrical to each other and are located diagonally above the crossbeam 9. The vertical braces 11 are set on the top of the long rib 8. There are two vertical braces 11 on the top of the long rib 8 on both sides of each egg-holding area 2. The height of the vertical braces 11 is flush with the reinforcing rib 3.

[0021] In some examples, the rounded corner rib 12 is located at the junction of the short rib 7, the long rib 8 and the outer frame 1, forming a rounded transition connection.

[0022] In some examples, rectangular ventilation holes 6 are designed around the outer frame 1. The ventilation holes 6 are symmetrically distributed in structure to facilitate ventilation.

[0023] The working principle of this invention is: The incubation tray proposed in this invention has an outer frame 1 on the outside and reinforcing ribs 3, short ribs 7 and long ribs 8 inside. The overall structure is simple and has high strength, thus ensuring the reliability and safety of the incubation tray during use.

[0024] Rectangular ventilation holes 6 are designed around the four sides of the outer frame 1. The ventilation holes 6 are symmetrically distributed in structure. The upper part of the incubation tray is the egg-holding area 2, and the bottom is the ventilation area. (See details below) Figure 3 As shown, this design ensures good overall air permeability, which is beneficial for the transfer and exchange of heat, moisture, and gases between the inside of the incubation tray and the external environment. refer to Figure 2 - Figure 3 As shown, the egg-holding area 2 inside the incubation tray can hold hatching eggs of different sizes ranging from 110 to 200g. The weight support points for hatching eggs ranging from 110 to 165g are on the short ribs 7, the crossbeams 9 and the horizontal supports 10, while the weight support points for hatching eggs ranging from 165 to 200g are on the short ribs 7, the crossbeams 9 and the vertical supports 11. Therefore, the compatibility is good.

[0025] In addition, the structural design of the egg-holding area 2 ensures that the hatching eggs remain within the egg-holding area 2 during large-angle egg-turning movements and do not slip out. Under the same vertical egg-turning angle, the smaller weight eggs swing at a larger angle, so the central axis reaches the horizontal state first (i.e., the angle between the central axis and the horizontal is 0 degrees).

[0026] The present invention designs the size of the egg holding area 2 based on the minimum weight of the egg, and designs a crossbeam 9 in the egg holding area 2 to make the egg turning process smoother, ensuring that the hatching egg will not be damaged due to abrupt movement when swinging from -70° to +70°. At the same time, the cooperation of the horizontal support 10 and the vertical support 11 can ensure that the hatching egg is turned with the big end facing up at any egg turning angle within ±70°.

[0027] in, Figure 4 The left image shows the angle between the central axis and the horizontal line when different sizes of hatching eggs are turned vertically at a 70° angle in the incubation tray (an angle greater than 0° indicates that the larger end is facing up). Figure 4 The right figure shows the turning angle of hatching eggs of different sizes in the horizontal direction. Specific data can be found in Table 1.

[0028] Table 1 shows the angle of hatching eggs when the vertical egg-turning angle of the incubation tray is 70°: ; Among them, when the hatching eggs do not slide (pure rolling), the maximum swing angle of a 200g hatching egg is 150.8°, the maximum swing angle of a 160g hatching egg is 155.6°, and the maximum swing angle of a 120g hatching egg is 162.6°.

[0029] Figure 5 The invention demonstrates the distance between hatching eggs when incubation trays are stacked. The distance from the bottom of the tray to the lowest weight of the hatching eggs is approximately 11.3 mm. The minimum distance between adjacent eggs on the same incubation tray is 2.8 mm, and the minimum distance between adjacent eggs at the same position on different trays is 2.1 mm, all within safe limits. Additionally, the four sets of support corners 4 facilitate positioning of the incubation trays during transport, and the stepped protrusions 5 increase the safe distance between the upper and lower incubation trays, preventing eggs at the same position on the upper and lower trays from being squeezed. Therefore, this invention enables the transport of incubation trays with eggs.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
