Description

Technical Field

[0001] The invention relates to the technical field of hatching equipment, and in particular to a hatching tray. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Incubation refers to the process of artificially simulating oviparous animals to create conditions such as temperature, humidity, and egg turning, and then developing fertilized eggs (breeding eggs) into life after a certain period of time. Incubation technology is used in farms, hatcheries, incubation laboratories of biological companies, incubation laboratories of schools, etc.

[0004] In hatcheries, large quantities of eggs are usually incubated, which requires placing the eggs in incubation trays, then placing the incubation trays on incubation carts, and finally pushing the incubation carts into incubators. Through system control, an incubation environment suitable for the development of eggs is created inside the incubator, including temperature, humidity, ventilation, egg turning, sanitation and disinfection, etc., to ultimately achieve the purpose of batch incubation. Therefore, the incubation tray must not only have a certain strength to place the eggs, but also have sufficient permeability to allow the eggs to transfer and exchange heat, moisture, gas and other substances with the surrounding environment. Therefore, the structure of the incubation tray has a direct impact on the incubation effect.

[0005] After a period of use, the existing incubation tray will bend downward due to the influence of the gravity of the eggs. This bending deformation is most obvious at the center of the incubation tray, and the distance between the eggs at the center will become smaller, which will not only affect the service life of the incubation tray, but also be detrimental to the transfer and exchange of substances. In addition, the existing incubation tray has good vertical permeability, but not good horizontal permeability, which causes different temperature, humidity and gas exchange at different points, and the progress of embryonic development is not concentrated, which ultimately leads to uneven hatching effects of eggs in the same incubation tray. Summary of the invention

[0006] In view of the shortcomings of the prior art, the object of the present invention is to provide a hatching tray with enhanced horizontal permeability and good hatching effect for eggs.

[0007] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0008] An embodiment of the present invention provides a hatching tray, comprising a base frame, wherein a plurality of cross-connected transverse connecting frames and longitudinal connecting frames are arranged inside the base frame, a plurality of saw teeth are arranged at intervals on the bottom edges of the transverse connecting frames and the longitudinal connecting frames, the transverse connecting frames and the longitudinal connecting frames constitute a plurality of egg tray spaces, an egg tray unit is arranged in the egg tray space, the egg tray unit comprises two arc-shaped bodies arranged opposite to each other, a plurality of protrusions with inner sides inclined outward are arranged on the top of the arc-shaped bodies to support the breeding eggs, the ends of the arc-shaped bodies are connected to the bottom ends of the saw teeth of the transverse connecting frames, the outer arc surface of the arc-shaped bodies is fixed to the bottom ends of the saw teeth of the longitudinal connecting frames, and a plurality of ventilation grooves are arranged on the sides of the base frame parallel to the longitudinal connecting frames.

[0009] Optionally, along the longitudinal direction of the hatching tray, the hatching tray is an arc-shaped structure that bulges upward.

[0010] Optionally, along the longitudinal direction of the hatching tray, the arc-shaped bodies on the same side in the adjacent egg tray spaces correspond to the connection positions of the saw teeth at the bottom of the transverse connecting frame.

[0011] Optionally, along the lateral direction of the hatching tray, in adjacent egg tray spaces, two arc-shaped bodies close to each other correspond to the connection positions of the bottom serrations of the longitudinal connecting frame therebetween.

[0012] Optionally, the inner diameter of the bottom of the arc-shaped body is smaller than the inner diameter of the top so that from bottom to top, the inner side surface of the arc-shaped body is inclined toward the outside and the inclination angle is smaller than the inclination angle of the inner side surface of the protrusion toward the outside.

[0013] Optionally, the longitudinal connecting frame includes thick parts and thin parts that are alternately arranged, the thickness of the thick part is greater than that of the thin part, the transverse connecting frame is cross-connected to the thick part of the longitudinal connecting frame, and the ground edge of the thin part is provided with serrations.

[0014] Optionally, a plurality of grooves are provided on the top edge of the longitudinal connecting frame, and the positions of the grooves correspond to the positions of the saw teeth at the bottom of the longitudinal connecting frame.

[0015] Optionally, in the egg tray unit, the multiple protrusions on the tops of the two arc-shaped bodies are distributed at equal intervals along the circumference of the circle where the two arc-shaped bodies are located.

[0016] Optionally, a boss is provided at the bottom edge of the base frame, and the boss is connected to a buckle plate extending downward. Correspondingly, a support plate corresponding to the buckle plate is provided at the side edge of the base frame to achieve stacking of the hatching trays.

[0017] Optionally, in the base frame, two side surfaces parallel to the longitudinal connecting frame are provided with support plates, and the other two side surfaces are provided with anti-slip stripes.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The hatching tray of the present invention has a plurality of saw teeth at the bottom edges of the horizontal connecting frame and the vertical connecting frame, and a space for gas circulation is formed between adjacent saw teeth. The end and the center position of the arc body are connected to the bottom ends of the saw teeth, and the base frame is arranged in the ventilation groove. The horizontal permeability of the entire hatching tray is good, and the exchange of temperature, humidity and gas at different points is uniform, thereby improving the hatching effect of the breeding eggs.

[0020] 2. In the hatching tray of the present invention, a plurality of arc-shaped grooves are arranged on the top edge of the longitudinal connecting frame, which further improves the horizontal permeability of the hatching tray.

[0021] 3. The hatching tray of the present invention has an arc-shaped body on the same side of adjacent egg tray spaces along the longitudinal direction of the hatching tray corresponding to the connection position of the serrations at the bottom of the horizontal connecting frame, and an arc-shaped body close to each other in adjacent egg tray spaces along the transverse direction of the hatching tray corresponds to the connection position of the serrations at the bottom of the vertical connecting frame between them. All egg tray units are connected as a whole. After the two arc-shaped bodies carry the breeding eggs, the pressure of the breeding eggs can be evenly diffused outward. Combined with the arc-shaped design of the entire hatching tray that is convex upward along the longitudinal direction, the bending deformation of the entire hatching tray after the breeding eggs are placed is avoided, so that a constant distance is maintained between the breeding eggs, thereby ensuring the hatching effect of the breeding eggs.

[0031] Example 1

[0032] This embodiment provides a hatching tray, such as Figure 1-Figure 3 As shown, a rectangular structure is adopted, with longitudinal and transverse directions. In the hatching tray, the shorter side is arranged along the longitudinal direction, and the longer side is arranged along the transverse direction. Along the longitudinal direction of the entire hatching tray, the hatching tray adopts an upwardly convex arc structure to form a crescent shape. This arrangement can offset the downward bending deformation of the center of the hatching tray after placing the breeding eggs.

[0033] The incubation tray comprises a base frame 1, which is a rectangular frame surrounded by four side panels, wherein two side panels distributed along the longitudinal direction are arc-shaped panels protruding upward, and two side panels distributed along the transverse direction are flat rectangular panels. With this arrangement, the entire incubation tray forms an arc-shaped structure protruding upward along the longitudinal direction.

[0034] Furthermore, an arc-shaped plate transition is adopted at the connection position of adjacent side panels, thereby avoiding the formation of a sharp angle structure at the connection position of adjacent side panels that may cause personal injury to the workers.

[0035] The inner space of the base frame 1 is provided with a plurality of vertically cross-fixed longitudinal connecting frames 2 and transverse connecting frames 3 , and both ends of the longitudinal connecting frames 2 and both ends of the transverse connecting frames 3 are fixedly connected to the base frame 1 .

[0036] A plurality of vertical connecting frames 2 and horizontal connecting frames 3 arranged vertically and crosswise form a mesh structure, forming a plurality of egg tray spaces arranged in a rectangular array.

[0037] Preferably, the egg tray space is a square space.

[0038] An egg tray unit is arranged in the egg tray space, and the egg tray unit is used for carrying breeding eggs.

[0039] The egg tray unit includes two arc-shaped bodies 4 arranged opposite to each other, the two arc-shaped bodies 4 are located on the same circumference, the center of the circumference is the center of the egg tray space, and the diameter of the bottom edge of the inner side of the arc-shaped body 4 is smaller than the diameter of the top edge, so that along the direction from bottom to top, the inner side surfaces of the two arc-shaped bodies 4 are inclined toward the outside to form a funnel-shaped structure.

[0040] A plurality of protrusions 5 are provided on the top of the arc-shaped body 4, and the inner side surface of the protrusion 5 is an arc surface matching the arc-shaped body 4, and the protrusion 5 is used to support the breeding eggs.

[0041] In this embodiment, the inner side surface of the protrusion 5 is also inclined toward the outside, and the angle of inclination toward the outside is greater than the angle of inclination of the inner side surface of the arc-shaped body 4 toward the outside. With this arrangement, the breeding eggs can be supported by the inner side surface of the protrusion 5.

[0042] like Figure 4 As shown, the breeding eggs are supported by the inner side of the protrusion 5. Compared with the current support method of using an isosceles triangle egg rack and a serrated card strip, the structure is simpler. When carrying breeding eggs of different specifications, no manual adjustment is required. It can automatically be compatible with breeding eggs of different specifications, is easy to use, and reduces the cost of materials and manual adjustment.

[0043] The hatching tray of this embodiment can accommodate the carrying requirements of eggs of different sizes ranging from 40g to 75g.

[0044] It is understandable that the angles at which the arc-shaped body 4 and the protrusion 5 are inclined toward the outside can be set according to actual needs, which will not be described in detail here.

[0045] In this embodiment, the multiple protrusions 5 on the top of the two arc-shaped bodies 4 are evenly spaced along the circumference of the circle where the arc-shaped bodies 4 are located, and the resistance in the longitudinal and transverse directions is the same, thereby ensuring the ventilation effect and the uniformity of the supporting force for the breeding eggs.

[0046] Specifically, two protrusions 5 are provided on the top of the two arc-shaped bodies 4, and the two protrusions 5 are symmetrically arranged relative to the center of the top of the arc-shaped body 4. The four protrusions 5 of the two arc-shaped bodies 4 are evenly spaced along the circumferential direction, that is, adjacent protrusions are spaced 90° apart, and the radial angle of each protrusion 5 with the longitudinal and lateral directions is 45°.

[0047] The bottom edge of the transverse connecting frame 3 is evenly spaced with a plurality of first saw teeth 6 , which are square saw teeth. It is understandable that the first saw teeth 6 may also be trapezoidal, arc-shaped or other shaped saw teeth, and a ventilation space is formed between two adjacent first saw teeth 6 .

[0048] The connection position between the longitudinal connecting frame 2 and the transverse connecting frame 3 is located above the middle of the ventilation space between adjacent first serrations 6 .

[0049] Furthermore, in order to facilitate the connection between the arc body 4 and the first saw teeth 6, the first saw teeth 6 are square saw teeth.

[0050] The end of the arc body 4 is fixedly connected to the bottom end of the corresponding first sawtooth 6, and along the longitudinal direction of the hatching tray, the arc bodies 4 on the same side of two adjacent egg tray units are aligned with the connection position of the same first sawtooth 6, so that the arc bodies 4 on the same side are not staggered in the longitudinal direction.

[0051] The longitudinal connecting frame 2 adopts an upwardly protruding arc structure that matches the shape of the base frame along the longitudinal direction. The bottom edge of the longitudinal connecting frame 2 is provided with a plurality of second serrations 7. The second serrations 7 are trapezoidal serrations. It can be understood that the second serrations 7 can also be square serrations or serrations of other shapes.

[0052] An air flow space is formed between two adjacent second serrations 7, thereby increasing the horizontal permeability of the entire hatching tray.

[0053] The middle position of the outer arc surface of the arc-shaped body 4 located at the non-edge of the base frame 1 is fixedly connected to the bottom end of the second serration 7, and a notch is set on the outer arc surface of the arc-shaped body 4 at the edge, and the end of the notch is directly fixedly connected to the inner side surface of the side plate of the base frame 1 or the middle position of the outer arc surface of the arc-shaped body 4 is directly fixedly connected to the inner side surface of the side plate of the base frame 1.

[0054] Along the lateral direction of the hatching tray, the arc-shaped bodies 4 in two adjacent egg tray units are aligned with the connection positions of the bottom ends of the second serrations 7 therebetween, so that along the center of the hatching tray, multiple arc-shaped bodies 4 in the same row are not staggered.

[0055] In this embodiment, all the arc bodies 4 are connected into a whole through the first serration 6 and the second serration 7. After the two arc bodies 4 carry the breeding eggs, the pressure of the breeding eggs can be evenly diffused outward. Combined with the arc design of the entire hatching tray that is convex upward along the longitudinal direction, the bending deformation of the entire hatching tray after the breeding eggs are placed is avoided, so that a constant distance is maintained between the breeding eggs, thereby ensuring the hatching effect of the breeding eggs.

[0056] Furthermore, the longitudinal connecting frame 2 includes a plurality of thick portions 2-1 and thin portions 2-2 that are alternately arranged, wherein the thickness dimension of the thick portion 2-1 is greater than the thickness dimension of the thin portion 2-2, and the second serration 7 is arranged in the middle position of the bottom edge of the thin portion 2-2. By arranging the thin portion 2-2, the weight of the entire longitudinal connecting frame 2 is reduced, thereby reducing the weight of the entire hatching tray.

[0057] The connection position between the longitudinal connecting frame 2 and the transverse connecting frame 3 is located in the middle of the thick portion 2 - 1 , thereby ensuring the connection strength between the longitudinal connecting frame 2 and the transverse connecting frame 3 .

[0058] In the base frame 1, two side panels parallel to the longitudinal connecting frame 2 are provided with a plurality of ventilation slots 8. Preferably, the ventilation slots 8 are long strip-shaped slots, and the positions of the ventilation slots correspond to the connection positions of the transverse connecting frame and the base frame, and the connection positions of the transverse connecting frame and the base frame are located above the middle positions of the ventilation slots.

[0059] In some other embodiments, the ventilation slots 8 may also be circular slots, square slots, or slots of other shapes, and those skilled in the art may configure them according to actual needs.

[0060] In this embodiment, by setting the first serration 6 and the second serration 7, the longitudinal connecting frame 2 and the transverse connecting frame 3 form a ventilation space, and the setting of the ventilation groove 8 greatly enhances the horizontal permeability of the hatching tray. The horizontal permeability of the entire hatching tray is good, and the temperature, humidity and gas are evenly exchanged at different points, thereby improving the hatching effect of the eggs.

[0061] In this embodiment, in order to further enhance the horizontal permeability of the entire hatching tray, a plurality of grooves are provided on the top edge of the longitudinal connecting frame 2. Preferably, the grooves are provided in the middle position of the top edge of the thin portion 2-2, corresponding to the position of the second serration 7.

[0062] In this embodiment, the groove is an arc-shaped groove 9 opened on the top edge of the longitudinal connecting frame. In some other embodiments, the groove may also be a square groove or a trapezoidal groove or other shapes of grooves. Those skilled in the art can choose according to actual needs.

[0063] Further, such as Figure 5 As shown, in order to achieve stacking of multiple layers of hatching trays for easy stacking, a boss 10 is provided at the bottom edge of the base frame, and a buckle plate 11 extending downward is provided at the outer end of the boss 10, and the inner side surface of the buckle plate 11 matches the outer side surface of the side plate of the base frame 1. Correspondingly, a support plate 12 is provided on the outer side surface of the side plate of the base frame 1. When the hatching trays on both sides are stacked, the bottom surface of the buckle plate 11 of the upper layer of hatching trays is placed on the top surface of the support plate 12 of the lower layer of hatching trays, thereby achieving stacking of two layers of hatching trays.

[0064] Preferably, in the base frame 1, support plates 12 are provided on the outer sides of the two side plates parallel to the longitudinal connecting frame. The support plates 12 are arranged perpendicular to the side plates and are arranged along the length direction of the side plates.

[0065] Furthermore, in order to facilitate the staff to manually take and place the hatching tray, an anti-slip stripe 13 is provided in the middle of the side plate of the base frame 1 parallel to the horizontal connecting frame.

[0066] In this embodiment, the anti-slip stripes 13 are composed of a plurality of long strip grooves formed on the surface of the side plate, thereby increasing the friction between the hand and the base frame 1 and facilitating the worker to take and place the hatching tray.

[0067] In some other embodiments, the anti-slip stripes 13 may also be a plurality of long strip-shaped protrusions arranged on the surface of the side panel, and those skilled in the art may select them according to actual needs.

[0068] In some other embodiments, a support plate 12 may be provided on the side panel surface of the base frame 1 parallel to the horizontal direction, and anti-slip stripes 13 may be provided on the two side panel surfaces parallel to the longitudinal direction. Alternatively, support plates 12 may be provided on all four side panel surfaces of the base frame 1. Those skilled in the art may arrange them according to actual needs, which will not be described in detail here.

[0069] With the hatching tray of this embodiment, for each egg tray unit, the inner side of the plurality of protrusions 5 supports the breeding eggs 14, such as Figure 6 As shown, when turning the eggs, the entire hatching tray rotates to a set angle, and the top positions of the horizontal connecting frame 3 and the vertical connecting frame 2 are used to limit the breeding eggs 14 to prevent the breeding eggs 14 from falling out.

[0070] It is understandable that the overall shape of the hatching tray may also be a square or other shapes, and those skilled in the art may select the shape according to actual needs.

[0071] The hatching tray of the present embodiment has high structural strength, and avoids bending deformation in the middle area after carrying the breeding eggs. At the same time, the ventilation space between the serrations and the ventilation slots 8 increase the horizontal permeability, ensuring sufficient ventilation and uniformity of the air volume in the horizontal direction inside the hatching tray. Moreover, the breeding eggs 14 are supported by the arc body 4 and the protrusion 5, which will not affect the vertical permeability, ensuring sufficient ventilation and uniformity of the air volume in the vertical direction, and improving the hatching effect of the breeding eggs.

[0072] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
