Description

Technical Field

[0001] The present invention relates to the technical field of hatching equipment, and specifically to a 54-egg hatching tray. Background Art

[0002] Hatching refers to the process of artificially simulating oviparous animals to create conditions such as temperature, humidity, and egg turning, and developing fertilized eggs (breeder eggs) into life after a certain period of time. The hatching technology is applied in farms, hatcheries, biological company hatching laboratories, school hatching laboratories, and so on.

[0003] In hatcheries, generally a large number of breeder eggs are hatched. First, the breeder eggs need to be placed in hatching trays, then the hatching trays are placed on hatching carts, and finally the hatching carts are pushed into the incubator. Through system control, an incubation environment suitable for the development of breeder eggs is created inside the incubator, including temperature, humidity, ventilation, egg turning, sanitation and disinfection, etc., ultimately achieving the purpose of batch hatching. Therefore, the hatching tray not only needs to have a certain strength and air permeability, but also a structure that can achieve large-angle egg turning for the breeder eggs. Especially for goose eggs, egg turning is an important condition to ensure the normal development of embryos. If the breeder eggs are not turned or the turning angle is insufficient during the hatching process, the embryo mortality rate will increase, and at the same time, the hatching rate will decrease. Egg turning also helps to guide and regulate the air flow inside the incubator and helps to avoid the emergence of high-temperature points. Therefore, the structure of the hatching tray has a direct impact on the hatching effect.

[0004] Most of the existing hatching trays have problems such as poor air permeability, poor compatibility, and the large end of the breeder eggs is prone to face downwards during large-angle egg turning. Therefore, further improvement is needed. For example, the Chinese patent with the authorization announcement number (CN217336989U) discloses an egg tray for an incubator. This egg tray has good air permeability and can enable the breeder eggs to slide smoothly during large-angle egg turning, and also has a certain compatibility with breeder eggs of different weights. However, this egg tray has quite a few defects. For example, for breeder eggs weighing less than 130g, the body of the eggs is slender, and the small end of the breeder eggs is prone to leak out from the egg holding unit, and its lowest position is lower than the fixed frame, which is likely to cause bumps and damages to the small end of the breeder eggs with small weights when placing the egg tray. Secondly, during hatching, large-angle egg turning will make the small end of the breeder eggs face upwards, which is likely to cause abnormal fetal positions and increase the stillbirth rate.

[0005] To solve the above problems, we propose a 54-egg hatching tray to solve the above problems. Summary of the Invention

[0006] To solve the problems in the background art, the present invention provides a 54-egg hatching tray.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows: A 54-egg incubation tray, the overall shape of the incubation tray is a rectangular cuboid with rounded corners, and it is composed of an outer frame, reinforcing ribs, support corners and an egg holding area; the egg holding area includes short ribs, long ribs, cross beams, cross braces, vertical braces and rounded corner ribs. The short ribs and the long ribs have the same height, are installed flush with each other up and down, and their bottom edges are higher than the bottom of the outer frame. The short ribs and the long ribs are vertically and evenly distributed in a grid pattern, dividing the inner cavity of the outer frame into 54 egg holding areas.

[0008] Preferably, the reinforcing ribs are located at the symmetrical center of the incubation tray, with their bottoms flush with the outer frame and their upper parts lower than the outer frame.

[0009] Preferably, the support corners are arranged at the four corners of the outer frame. The support corners are higher than the outer frame, and their outer shapes are frustum-shaped, with convex platforms provided at the tops.

[0010] Preferably, the cross beams are located at the inner bottom of the egg holding area. The cross beams are narrow in the middle and wide at both sides in shape. The bottoms of the cross beams are flush with the bottoms of the short ribs, and the two ends are connected to the long ribs, and the edges of the cross beams have rounded transitions.

[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 sides of the long ribs. The two groups of cross braces are symmetric with each other left and right and are both located obliquely above the cross beams.

[0012] Preferably, the vertical braces are arranged at the tops of the long ribs. Two vertical braces are provided at the tops of the long ribs on both sides of each egg holding area. The height of the vertical braces is flush with that of the reinforcing ribs.

[0018] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows: Embodiment: Refer to Figure 1 - Figure 5 As shown in the figure, a 54-egg hatching tray in this embodiment includes that the overall shape of the hatching tray is a cuboid with rounded corners, and it is composed of an outer frame 1, a reinforcing rib 3, a support angle 4, and an egg holding area 2; the egg holding area 2 includes short ribs 7, long ribs 8, cross beams 9, cross braces 10, vertical braces 11, and rounded corner ribs 12. The short ribs 7 and the long ribs 8 have the same height and are installed flush with each other up and down, and their bottom edges are all higher than the bottom of the outer frame 1. The short ribs 7 and the long ribs 8 are vertically and evenly distributed 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 area 2 are type.

[0019] Among them, the reinforcing rib 3 is located at the symmetrical center of the hatching tray, its bottom is flush with the outer frame 1, and its upper part is lower than the outer frame 1; the support angles 4 are arranged at the four corners of the outer frame 1, the support angles 4 are higher than the outer frame 1, and their outer shapes are frustum-shaped, and a boss 5 is provided at the top. The boss 5 can be inserted into the conical hole at the bottom of the support angle 4, so that the hatching trays can be stacked and placed.

[0020] The cross beam 9 is located at the inner bottom of the egg holding area 2. The outer shape of the cross beam 9 is narrow in the middle and wide at both sides. The bottom of the cross beam 9 is flush with the bottom of the short ribs 7, and both ends are connected to the long ribs 8, and its edges have rounded transitions; the cross braces 10 are arranged on both sides of the inner cavity of the egg holding area 2 and are fixedly connected to the side surfaces of the long ribs 8. The two groups of cross braces 10 are symmetric with each other left and right and are both located obliquely above the cross beam 9; the vertical braces 11 are arranged at the tops of the long ribs 8, and two vertical braces 11 are provided at the tops of the long ribs 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, and is connected in an arc-shaped transition.

[0022] In some examples, rectangular ventilation holes 6 are designed on the four sides of the outer frame 1. The ventilation holes 6 are symmetrically distributed in structure, facilitating ventilation.

[0023] The working principle of the present invention is: The incubation tray proposed by the present invention has an outer frame 1 on the periphery, 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] Among them, rectangular ventilation holes 6 are designed on the four sides of the outer frame 1. The ventilation holes 6 are symmetrically distributed in structure, and the upper part of the incubation tray is the egg holding area 2, and the bottom is the ventilation area. Specifically refer to Figure 3 as shown, so that the overall air permeability is good, which is conducive to the transfer and exchange of heat, moisture, gas and other substances between the inside of the incubation tray and the external environment; Refer to Figure 2 - Figure 3 as shown, the internal egg holding area 2 of the incubation tray can hold different specifications of breeding eggs weighing 110 - 200g. The gravity fulcrums of the breeding eggs weighing 110 - 165g are on the short ribs 7, the cross beams 9 and the cross braces 10, while the gravity fulcrums of the breeding eggs weighing 165 - 200g are on the short ribs 7, the cross beams 9 and the vertical braces 11. Therefore, the compatibility is relatively good.

[0025] In addition, the structural design of the egg holding area 2 can ensure that the breeding eggs are always located within the egg holding area 2 during large-angle egg turning operations and do not slip off. At the same vertical egg turning angle, the small-weight eggs have a larger swinging angle, so the central axis reaches the horizontal state first (that is, 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 smallest-weight eggs, and a cross beam 9 is designed in the egg holding area 2 to make the egg turning process smoother, ensuring that the breeding eggs will not be damaged due to sudden movements when swinging from -70° to +70°. At the same time, the cooperation of the cross braces 10 and the vertical braces 11 can ensure that the breeding eggs are big-end up at any egg turning angle within ±70°.

[0027] Among them, Figure 4 The left figure shows the angle between the central axis and the horizontal line when the incubation tray is vertically turned at an angle of 70° for different specifications of breeding eggs (an angle greater than 0° indicates the big end is up), Figure 4 and the right figure shows the egg turning angle of different specifications of breeding eggs in the horizontal direction. The specific data are shown in Table 1.

[0028] Table 1 shows the angles of the breeding eggs when the incubation tray is vertically turned at an angle of 70°: ; Among them, when the hatching eggs do not slide (pure rolling), the maximum swing angle of 200g hatching eggs is 150.8°, the maximum swing angle of 160g hatching eggs is 155.6°, and the maximum swing angle of 120g hatching eggs is 162.6°.

[0029] Figure 5 It shows the distance between hatching eggs when the hatching trays are stacked. The distance between the hatching eggs with a small weight and the bottom of the egg tray is about 11.3mm. The minimum distance between adjacent hatching eggs in the same hatching tray is 2.8mm, and the minimum distance between adjacent hatching eggs at the same position up and down is 2.1mm, all within the safe range. In addition, the four sets of supporting angles 4 can facilitate the positioning of the hatching tray during transportation, and the stepped convex platform 5 increases the safety distance between the upper and lower hatching trays, avoiding the extrusion of hatching eggs at the same position of the upper and lower trays. Therefore, the present invention can realize the transportation of hatching trays with eggs.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
