Description

Technical Field

[0001] This invention relates to the technical field of chick placement boxes with preheating structures, specifically a chick placement box with a preheating structure for chick incubation. Background Technology

[0002] Chicks generally refer to young chickens, which are animals belonging to the genus *Gallus* in the family Phasianidae of the order Galliformes. They are the offspring of chickens, hatched from eggs by the mother hen. Newly hatched chicks are small, delicate, and have short downy feathers, making them the most commonly raised poultry by humans. During the incubation process, the eggs need to be preheated to ensure a high hatching rate.

[0003] Current chick incubation devices can basically meet people's usage requirements. However, during incubation, the eggs need to be manually turned. The main purpose of turning the eggs is to change the position of the embryo, prevent adhesion, ensure even heating of all parts of the embryo, supply fresh air, and promote embryonic development. Turning also helps embryonic movement, improves blood circulation in the fetal membranes, and increases the hatching rate. However, manual egg turning in current chick incubators is time-consuming and labor-intensive, reducing chick production. Summary of the Invention

[0004] The purpose of this invention is to provide a chick placement box with a preheating structure for chick incubation, so as to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] This invention relates to a chick hatching box with a preheating structure, comprising a box body, several support columns fixedly connected to the bottom of the box body, a heating box opened at the bottom of the box body, several incubation chambers opened inside the box body, incubation drawers slidably connected inside the incubation chambers, several incubation drawers holding several incubation eggs, and a box door rotatably connected to the front of the box body. It also includes:

[0007] The preheating section is installed inside the chamber. The preheating section is used to provide heat for the hatching eggs and drive the circulation of heat inside the chamber to provide sufficient heat and oxygen for the hatching eggs.

[0008] The incubation section, installed inside the incubation drawer, is used to adjust the incubation angle of the eggs; and

[0009] The incubation section also provides automatic turning of the hatching eggs to prevent the embryo inside the egg from sticking to the inner wall of the eggshell, while ensuring that all parts of the embryo are heated evenly.

[0010] Furthermore, the preheating section includes:

[0011] The preheating element is installed inside the heating box. The preheating element is used to heat the air and provide driving force for the heating circulation.

[0012] The circulation component, installed inside the box, is used to evenly distribute the warm air generated by the placement component to the area around the eggs inside the incubation drawer, ensuring a suitable incubation temperature for the eggs.

[0013] Furthermore, the preheating component includes a heating wire fixedly connected to the inner wall of the heating chamber. An air inlet is provided on the side wall of the heating chamber, which can replace the air inside the chamber to ensure sufficient oxygen inside the chamber. An air pump is fixedly connected inside the heating chamber, and a manifold is fixedly connected to the output port of the air pump.

[0014] Furthermore, the circulation component includes several air blowing pipes fixedly connected to the collecting pipe, and several air outlet branch pipes fixedly connected to the end of the air blowing pipes away from the collecting pipe. Several air blowing holes are opened on the side wall of the air outlet branch pipes, and the air blowing holes are used to blow warm air around the incubation eggs.

[0015] Among them, several circulation pipes are fixedly connected to one side of the air blowing pipe of the heating box, and several exhaust branch pipes are fixedly connected to the end of the circulation pipe away from the heating box. Several circulation holes are opened on the side wall of the exhaust branch pipe. The circulation holes are used to discharge the gas inside the incubation drawer into the heating box, thereby forming an airflow circulation.

[0016] Furthermore, the incubation department includes:

[0017] The placement component is installed inside the incubation drawer and is used to hold several incubation eggs;

[0018] The rotating component is installed on the inner walls of both sides of the incubation drawer. The rotating component is used to adjust the angle of the incubation eggs on the placement component.

[0019] Egg-turning device: The egg-turning device is installed on both outer walls of the incubation drawer. The incubation drawer is used to rotate the incubation eggs to complete the egg-turning process.

[0020] Furthermore, the placement component includes several limiting grooves formed on the inner walls of both sides of the incubation drawer, with an angle adjustment shaft rotatably connected inside the limiting grooves, and an incubation rack fixedly connected to the end of the angle adjustment shaft away from the inner wall of the incubation drawer.

[0021] Furthermore, the placement component also includes a breathable pad fixedly connected to the inside of the incubation rack. The breathable pad has several grooves, which are used to support the incubation eggs placed at an angle. Several rotating bases are rotatably connected to the bottom of the incubation rack, and the incubation eggs are placed directly above the rotating bases.

[0022] Furthermore, the rotating component includes several friction drive wheels rotatably connected to the inner walls on both sides of the incubation drawer. The top of the friction drive wheels presses against the top of the incubation chamber, and a gear is fixedly connected to the side of the friction drive wheel away from the inner wall of the incubation drawer.

[0023] Furthermore, the rotating component also includes a second gear fixedly connected to the end of the angle adjustment shaft away from the limiting groove. The second gear meshes with the first gear. A limiting block is fixedly connected to the end of the angle adjustment shaft near the limiting groove. The limiting block is slidably connected inside the limiting groove. The limiting block is used to limit the rotation amplitude of the placed component. A compression spring is fixedly connected to one end of the limiting block.

[0024] Furthermore, the egg-turning component includes a pressing wheel fixedly connected to the bottom of the rotating base, several rotating shafts rotatably connected to the outer walls of both sides of the incubation drawer, a gear three fixedly connected to the bottom of the innermost rotating shaft of the incubation drawer, and several transmission belts drivingly connecting the several rotating shafts.

[0025] The rotating shaft is connected to a friction belt in the middle, and several racks are fixedly connected to the inner wall of the housing. The racks are used to engage with gear three, thereby driving the rotating shaft to rotate by meshing the racks with gear three.

[0026] The present invention has the following beneficial effects:

[0027] (1) In this invention, when it is necessary to turn the hatched eggs, the operator pulls the hatching drawer outward along the hatching cavity. At this time, the friction drive wheel on the side wall of the hatching drawer is squeezed against the top of the hatching cavity. Under the drive of friction, the friction drive wheel rotates and drives the gear two at the bottom of the gear one to rotate. The gear two drives several hatched eggs on the hatching rack on the angle adjustment shaft to change from an inclined state to a vertical state. This setting is conducive to the operator to conduct random inspection of the hatched eggs. On the other hand, the weight of the hatched eggs in the vertical state is completely applied to the top of the rotating base. This setting is conducive to the rotation of the rotating base to drive the hatched eggs to rotate, thereby making the egg turning process more stable and smooth.

[0028] (2) In this invention, when using the chick hatching placement box, several eggs to be hatched are first placed on the breathable pad inside the placement box. Air enters the heating box through the air inlet and is then heated by the heating wire. The air pump delivers the heated air to the inside of the hatching drawer through the air outlet branch pipe on the air blowing pipe, thereby maintaining a constant temperature inside the hatching drawer. In addition, while the heated air is discharged into the inside of the hatching drawer through the air outlet branch pipe, the gas inside the hatching drawer enters the discharge branch pipe through the circulation hole and is then discharged into the heating box through the circulation pipe. This setting helps to ensure air circulation inside the hatching drawer, ensures sufficient oxygen inside the hatching drawer, and helps to improve the hatching rate of the eggs.

[0029] (3) In this invention, when the angle adjustment shaft drives the hatching eggs on the hatching rack to be placed vertically, the hatching rack drives several extrusion wheels at the bottom to extrude pressure from the friction belt. When the hatching drawer continues to slide outward, gear three meshes with the rack, the rack drives the rotating shaft on gear three to rotate, the rotating shaft drives the friction belt to rotate, and at this time the friction belt drives the rotating base at the top of the extrusion wheel to rotate, and the rotating base drives the hatching eggs at the top to rotate and turn, so that the hatching eggs automatically complete the egg-turning process, thereby achieving twice the result with half the effort.

[0030] (4) In this invention, when the incubation drawer is pushed into the incubation chamber, the friction drive wheel is driven by the friction force at the top of the incubation chamber, and the friction drive wheel drives the incubation rack on the bottom angle adjustment shaft of the gear to rotate, so that the incubation eggs on the incubation rack are placed at an angle. The incubation eggs placed at an angle are conducive to the normal development and growth of the embryo, thereby improving the survival rate of the incubation eggs.

[0031] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Example 1, please refer to Figure 1-Figure 5 As shown, this invention is a chick-holding box with a preheating structure for chick incubation, comprising a box body 1, several support columns 11 fixedly connected to the bottom of the box body 1, a heating box 12 opened at the bottom of the box body 1, several incubation chambers 13 opened inside the box body 1, incubation drawers 14 slidably connected inside the incubation chambers 13, several incubation eggs 316 placed inside the incubation drawers 14, and a box door 15 rotatably connected to the front of the box body 1, and further comprising:

[0048] The preheating unit 2 is installed inside the box 1. The preheating unit 2 is used to provide heat for the hatching of the eggs 316 and drive the circulation of heat inside the box 1 to provide sufficient heat and oxygen for the hatching of the eggs 316.

[0049] Hatching section 3, installed inside hatching drawer 14, is used to adjust the hatching angle of hatching eggs 316; and

[0050] The incubation section 3 is also used to provide automatic turning of the incubation eggs 316, to prevent the embryo inside the incubation eggs 316 from sticking to the inner wall of the eggshell, and to ensure that all parts of the embryo are heated evenly.

[0051] Preheating section 2 includes:

[0052] Preheating component 21 is installed inside the heating box 12. The preheating component 21 is used to heat the air and provide driving force for the heating circulation.

[0053] The circulation component 22 is installed inside the box 1. The circulation component 22 is used to evenly transport the warm air generated by the placement component 31 to the area around the incubation eggs 316 inside the incubation drawer 14, so as to ensure that the incubation temperature of the incubation eggs 316 is suitable.

[0054] The preheating component 21 includes a heating wire 211 fixedly connected to the inner wall of the heating box 12. An air inlet 212 is provided on the side wall of the heating box 12. The air inlet 212 can replace the air inside the box 1 to ensure sufficient oxygen inside the box 1. An air pump 213 is fixedly connected inside the heating box 12. A manifold 214 is fixedly connected to the output port of the air pump 213.

[0055] The circulation component 22 includes several air blowing pipes 221 fixedly connected to the collection pipe 214. Several air outlet branches are fixedly connected to the end of the air blowing pipe 221 away from the collection pipe 214. Several air blowing holes 222 are opened on the side wall of the air outlet branches. The air blowing holes 222 are used to blow warm air around the incubation egg 316.

[0056] The heating chamber 12 has several circulation pipes 223 fixedly connected to one side of the air blowing pipe 221. Several exhaust branch pipes are fixedly connected to the end of the circulation pipe 223 away from the heating chamber 12. Several circulation holes 224 are opened on the side wall of the exhaust branch pipe. The circulation holes 224 are used to discharge the gas inside the incubation drawer 14 into the heating chamber 12, thereby forming an airflow circulation. The function of this component is that air enters the heating chamber 12 through the air inlet 212, and then the air is heated by the heating wire 211. The air pump 213 delivers the heated air to the incubation drawer 14 through the air outlet branch pipe on the air blowing pipe 221, thereby maintaining a constant temperature inside the incubation drawer 14. In addition, when the heated air is discharged into the incubation drawer 14 through the air outlet branch pipe, the gas inside the incubation drawer 14 enters the exhaust branch pipe through the circulation hole 224 and then is discharged into the heating chamber 12 through the circulation pipe 223. This setting helps to ensure air circulation inside the incubation drawer 14, ensures sufficient oxygen inside the incubation drawer 14, and helps to improve the hatching rate of the eggs 316.

[0057] Example 2 differs from Example 1 in that: Figures 1-11 As shown, incubation section 3 includes:

[0058] Placement component 31 is installed inside the incubation drawer 14 and is used to place several incubation eggs 316.

[0059] Rotating component 32 is installed on the inner walls of both sides of the incubation drawer 14. Rotating component 32 is used to adjust the angle of the incubation egg 316 on the placement component 31.

[0060] Egg-turning component 33 is installed on both outer walls of the incubation drawer 14. The incubation drawer 14 is used to rotate the incubation egg 316 to complete the egg-turning process.

[0061] The placement component 31 includes several limiting grooves 311 formed on the inner walls of both sides of the incubation drawer 14. An angle adjustment shaft 312 is rotatably connected inside the limiting groove 311. An incubation rack 313 is fixedly connected to one end of the angle adjustment shaft 312 away from the inner wall of the incubation drawer 14.

[0062] The placement component 31 also includes a breathable pad 314 fixedly connected to the inside of the incubation rack 313. The breathable pad 314 is provided with several grooves, which are used to support the incubation eggs 316 placed at an angle. Several rotating bases 315 are rotatably passed through the bottom of the incubation rack 313, and the incubation eggs 316 are placed directly above the rotating bases 315.

[0063] The rotating component 32 includes several friction drive wheels 321 rotatably connected to the inner walls on both sides of the incubation drawer 14. The top of the friction drive wheels 321 presses against the top of the incubation chamber 13. A gear 322 is fixedly connected to the side of the friction drive wheels 321 away from the inner wall of the incubation drawer 14.

[0064] The rotating component 32 also includes a second gear 323 fixedly connected to the end of the angle adjusting shaft 312 away from the limiting groove 311. The second gear 323 meshes with the first gear 322. A limiting block 324 is fixedly connected to the end of the angle adjusting shaft 312 near the limiting groove 311. The limiting block 324 is slidably connected inside the limiting groove 311 and is used to limit the rotation range of the placement component 31. A compression spring 325 is fixedly connected to one end of the limiting block 324. The function of this component is that when it is necessary to turn the incubation eggs 316, the operator pulls the incubation drawer 14 outward along the incubation cavity 13. At this time, the side wall of the incubation drawer 14... The friction drive wheel 321 presses against the top of the incubation chamber 13. Driven by friction, the friction drive wheel 321 rotates, which in turn drives the gear 2 323 at the bottom of the gear 1 322 to rotate. The gear 2 323 drives several incubation eggs 316 on the incubation rack 313 on the angle adjustment shaft 312 to change from an inclined state to a vertical state. This setting is conducive to the operator to conduct random inspections of the incubation eggs 316. On the other hand, the weight of the incubation eggs 316 in the vertical state is completely applied to the top of the rotating base 315. This setting is conducive to the rotation of the rotating base 315 to drive the rotation of the incubation eggs 316, thereby making the egg turning process more stable and smooth.

[0065] The egg-turning component 33 includes a pressing wheel 331 fixedly connected to the bottom of the rotating base 315, and several rotating shafts 332 rotatably connected to the outer walls of both sides of the incubation drawer 14. A gear 333 is fixedly connected to the bottom of the innermost rotating shaft 332 of the incubation drawer 14, and several transmission belts 335 are connected between the several rotating shafts 332.

[0066] The rotating shaft 332 is connected to a friction belt 334 at its center. Several racks 336 are fixedly connected to the inner wall of the housing 1. The racks 336 engage with gear 333, thus driving the rotating shaft 332 to rotate. The function of this component is that when the angle adjustment shaft 312 causes the hatching eggs 316 on the incubation rack 313 to be placed vertically, the incubation rack 313 causes several pressing wheels 331 at its bottom to press against the friction belt 334. When the incubation drawer 14 continues to slide outwards, gear 333 meshes with the racks 336, causing the racks 336 to drive the rotating shaft 332 on the gear 333 to rotate. The rotating shaft 332 then drives the friction belt 334... When the friction belt 334 rotates, the rotating base 315 on top of the squeezing wheel 331 rotates, and the rotating base 315 rotates the hatching egg 316 on top to rotate and turn the egg, so that the hatching egg 316 automatically completes the egg turning process, thus achieving twice the result with half the effort. When the hatching drawer 14 is pushed into the hatching chamber 13, the friction drive wheel 321 is driven by the friction force on the top of the hatching chamber 13, and the friction drive wheel 321 drives the hatching rack 313 on the angle adjustment shaft 312 at the bottom of the gear 322 to rotate, so that the hatching egg 316 on the hatching rack 313 is placed at an angle. The tilted placement of the hatching egg 316 is conducive to the normal development and growth of the embryo, thereby improving the survival rate of the hatching egg 316.

[0067] A specific application of this embodiment is as follows: When using the chick incubation box, several eggs 316 to be incubated are first placed on the breathable pad 314 inside the placement component 31. Air enters the heating chamber 12 through the air inlet 212, and is then heated by the heating wire 211. The air pump 213 delivers the heated air to the incubation drawer 14 through the air outlet branch pipe on the air blower 221, thereby maintaining a constant temperature inside the incubation drawer 14. Additionally, while the heated air is discharged into the incubation drawer 14 through the air outlet branch pipe, the gas inside the incubation drawer 14 enters the discharge branch pipe through the circulation hole 224 and is then discharged into the heating chamber 12 through the circulation pipe 223. This arrangement helps ensure air circulation inside the incubation drawer 14, ensuring sufficient oxygen inside the incubation drawer 14, which is beneficial for improving... The hatching rate of high-hatching eggs 316 is achieved by the operator pulling the hatching drawer 14 outward along the hatching chamber 13 when the eggs need to be turned. At this time, the friction drive wheel 321 on the side wall of the hatching drawer 14 is pressed against the top of the hatching chamber 13. Under the influence of friction, the friction drive wheel 321 rotates, which in turn drives the gear 2 323 at the bottom of the gear 1 322 to rotate. The gear 2 323 drives several eggs 316 on the hatching rack 313 on the angle adjustment shaft 312 to change from an inclined state to a vertical state. This setting is beneficial for the operator to conduct random checks on the eggs 316. On the other hand, the weight of the eggs 316 in the vertical state is completely applied to the top of the rotating base 315. This setting is beneficial for the rotating base 315 to rotate and drive the eggs 316 to rotate, thus making the egg-turning process more stable and smooth.

[0068] When the angle adjustment shaft 312 causes the hatching eggs 316 on the incubation rack 313 to be placed vertically, the incubation rack 313 causes several compression rollers 331 at the bottom to compress against the friction belt 334. As the incubation drawer 14 continues to slide outward, gear 333 meshes with rack 336. Rack 336 drives the rotating shaft 332 on gear 333 to rotate. The rotating shaft 332 drives the friction belt 334 to rotate. At this time, the friction belt 334 drives the rotating base 315 on top of the compression rollers 331 to rotate. By setting the number of teeth on rack 336, it is possible to drive the rotating base 315 to rotate 180°, thus making the top of the rotating base 315 rotate. The hatching egg 316 is rotated 180°, and the rotating base 315 drives the top hatching egg 316 to rotate and turn, so that the hatching egg 316 automatically completes the egg-turning process, thus achieving twice the result with half the effort; when the hatching drawer 14 is pushed into the hatching chamber 13, the friction drive wheel 321 is driven by the friction force at the top of the hatching chamber 13, and the friction drive wheel 321 drives the hatching rack 313 on the angle adjustment shaft 312 at the bottom of the gear 322 to rotate, so that the hatching egg 316 on the hatching rack 313 is placed at an angle. The tilted placement of the hatching egg 316 is conducive to the normal development and growth of the embryo, thereby improving the survival rate of the hatching egg 316.
