Description

Technical Field

[0001] This utility model relates to the field of breeding equipment technology, and in particular to a high-density stacked layer hen breeding equipment. Background Technology

[0002] In modern poultry farming, high-density, large-scale farming has become the mainstream trend in order to maximize the use of limited farming space, improve land utilization, and reduce unit costs. Stacked cage rearing, as a key technology, significantly increases the rearing capacity per unit area by vertically stacking chicken cages, and is an important equipment foundation for achieving intensive and automated farming.

[0003] Currently, most commercially available stacked layer hen rearing equipment consists of a fixed, integral structure made of welded metal frames or bolted together. In this design, the vertical distance between the upper and lower cages is determined during manufacturing, resulting in a fixed, unchangeable layer height. This standardized layer height is typically designed based on the average size of adult layer hens, aiming to provide a universally suitable living space for flocks during peak egg production. The structural design focuses on overall stability and durability.

[0004] However, in actual breeding and management, this fixed-height design has revealed significant limitations. The growth cycle of laying hens includes several stages with vastly different body sizes, from chicks and pullets to adult laying hens. For small pullets, configuring cages with the height of adult chickens results in a significant waste of vertical space, reducing the space utilization efficiency of the equipment at specific stages and potentially hindering centralized management and heat preservation due to excessive space. Conversely, if the cage height is improperly designed, it may feel too cramped for larger adult chickens, restricting their necessary activities such as head lifting and standing, which can negatively impact their health and egg production performance in the long run. Therefore, a high-density stacked laying hen breeding system is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-density stacked layer hen breeding equipment, which aims to improve the problem that the existing equipment cannot adjust the equipment space at specific times, thus making the breeding equipment space unfavorable for centralized management and heat preservation of the flock.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-density stacked layered hen breeding equipment, comprising a lower cage and an upper cage, wherein the lower cage and the upper cage are alternately slidably arranged, a cage door is rotatably connected to the lower surface of the upper cage, a cage door is slidably arranged on the outer wall of the cage door, the cage door is locked to the lower cage by a snap-fit ​​connection, and an adjustment component is installed on one side of the outer wall of the lower cage.

[0007] The adjustment assembly includes a first crossbar, one side of which is fixedly connected to the outer wall of the lower cage. Support cylinders are fixedly connected to both ends of the first crossbar. Support rods are slidably connected inside both support cylinders. A second crossbar is fixedly connected between the two support rods. One side of the second crossbar is fixedly connected to the outer wall of the upper cage. An extension rod is fixedly connected to the upper surface of the second crossbar. Hinge seats are fixedly connected to one side of the outer wall of each support cylinder. A bidirectional lead screw is rotatably connected to the outer wall of one hinge seat. The other end of the bidirectional lead screw passes through the interior of the other hinge seat. A symmetrical slider is threaded onto the outer wall of the bidirectional lead screw. A support plate is rotatably connected to the upper surface of the slider. A hinge block is rotatably connected to the upper side of the support plate.

[0008] As a further description of the above technical solution:

[0009] A feeding box is fixedly connected to the outer wall of the lower cage near the buckle, and a gap for the laying hens to eat is provided on the side of the lower cage near the feeding box.

[0010] As a further description of the above technical solution:

[0011] A limiting plate is fixedly connected to the outer wall of the support cylinder near the lower cage, and a manure collection tray is slidably connected to the upper surface of the limiting plate.

[0012] As a further description of the above technical solution:

[0013] A water inlet pipe is fixedly connected inside the upper cage, and multiple drain pipes are fixed on the lower side of the outer wall of the water inlet pipe.

[0014] As a further description of the above technical solution:

[0015] Multiple drinking hoppers are fixedly connected to the outer wall of the water inlet pipe near the drain pipe, and the outlet of the drain pipe is located directly above the drinking hoppers.

[0016] As a further description of the above technical solution:

[0017] A second support plate is fixedly connected to the lower surface of the support cylinder, and multiple casters are installed on the lower surface of the second support plate.

[0018] As a further description of the above technical solution:

[0019] A handrail is fixedly connected to the upper surface of the second support plate near the lower cage, and the handrail is used by the operator to drive the second support plate to move.

[0020] As a further description of the above technical solution:

[0021] The upper surface of the hinge block is fixedly connected to the lower surface of the crossbar, and a limit rod is fixedly connected to the outer wall of the support rod. The outer wall of the limit rod slides through the support cylinder.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, by rotating the bidirectional lead screw, the upper cage can be smoothly and vertically raised and lowered via a threadedly connected slider and a hinged support plate. The core advantage of this design is that breeders can flexibly set the most suitable cage height according to the size of the laying hens at different growth stages, ensuring that the chickens have sufficient space to move around, avoiding confinement and injury, while effectively saving and utilizing vertical space. This adjustment process is labor-saving, precise, and stable, greatly improving the scientific nature and flexibility of breeding practices.

[0034] Reference Figures 1-6This utility model provides an embodiment of a high-density stacked layer hen breeding device, comprising a lower cage 1 and an upper cage 2, wherein the lower cage 1 and the upper cage 2 are alternately slidably arranged to facilitate functional operation and management; a cage door 3 is rotatably connected to the lower surface of the upper cage 2 to facilitate opening and closing of the cage door, and a second cage door 4 is slidably arranged on the outer wall of the first cage door 3 to form a double-door structure; the second cage door 4 is connected and locked to the lower cage 1 by a buckle 5 to ensure that the cage door is firmly closed and to prevent the laying hens from escaping accidentally; an adjustment component is installed on one side of the outer wall of the lower cage 1, which is used to adjust the upper and lower cage 1 The spacing is adjusted; the adjustment assembly includes a crossbar 7, one side of which is fixedly connected to the outer wall of the lower cage 1, serving as a stable base for the entire adjustment assembly; both ends of the crossbar 7 are fixedly connected to support cylinders 6, providing vertical guidance for the lifting and lowering of the upper cage 2; support rods 8 are slidably connected inside the two support cylinders 6, thereby achieving relative vertical movement of the upper and lower cages 1; a crossbar 10 is fixedly connected between the two support rods 8, used to synchronously connect the two support rods 8 and support the upper cage 2; one side of the outer wall of the crossbar 10 is fixedly connected to the outer wall of the upper cage 2, thereby adjusting the spacing. The motion of the components is transmitted to the upper cage 2; an extension rod 11 is fixedly connected to the upper surface of the crossbar 2 10, and its structure can be inserted and matched with the bottom of the support cylinder 6 of another set of the same equipment to achieve stable stacking of multi-layer equipment; a hinge seat 12 is fixedly connected to one side of the outer wall of each of the two support cylinders 6 to provide a mounting fulcrum for the drive device; a bidirectional lead screw 13 is rotatably connected to the outer wall of one hinge seat 12, and the other end of the bidirectional lead screw 13 passes through the interior of the other hinge seat 12 to support the lead screw and allow it to rotate; a symmetrical slider 14 is threadedly connected to the outer wall of the bidirectional lead screw 13 to rotate the lead screw. The motion is converted into synchronous horizontal linear motion of slider 14; a support plate 15 is rotatably connected to the upper surface of slider 14, and a hinge block 16 is rotatably connected to the upper side of support plate 15. The support plate and hinge block 16 constitute a linkage mechanism that converts horizontal motion into vertical lifting force; the upper surface of hinge block 16 is fixedly connected to the lower surface of crossbar 10, so that the lifting force is directly applied to the upper cage 2 frame; a limit rod 9 is fixedly connected to the outer wall of support rod 8, and the outer wall of limit rod 9 slides through support cylinder 6 to prevent support rod 8 from rotating during lifting and ensuring the stability of lifting.

[0035] Specifically, by rotating the bidirectional lead screw 13, the slider 14 is driven to move towards or away from each other. Then, through the linkage mechanism composed of the support plate 15 and the hinge block 16, the horizontal displacement of the slider 14 is efficiently converted into the vertical lifting and lowering of the upper cage 2, thereby achieving precise adjustment of the cage height to adapt to the feeding needs of laying hens at different growth stages. At the same time, the plug-in design of the extension rod 11 and the support cylinder 6 provides a stable connection for the vertical stacking of multiple units, greatly improving space utilization and meeting the requirements of high-density breeding.

[0036] Reference Figures 1-6A feeding box 17 is fixedly connected to the outer wall of the lower cage 1 near the buckle 5. A gap for the laying hens to eat is provided on the side of the lower cage 1 near the feeding box 17, providing a concentrated feeding area for the hens. A limiting plate 18 is fixedly connected to the outer wall of the support cylinder 6 near the lower cage 1. A manure collection tray 19 is slidably connected to the upper surface of the limiting plate 18. This structure is used to collect the excrement from the upper cage 2 and facilitates its removal for cleaning, thus ensuring hygiene in stacked rearing. A water inlet pipe 20 is fixedly connected inside the upper cage 2. Multiple drain pipes 21 are fixed to the lower side of the outer wall of the water inlet pipe 20. This combination constitutes the main pipeline of the automatic drinking water system. The water source is distributed to various drinking points; multiple drinking troughs 22 are fixedly connected to the outer wall of the water inlet pipe 20 near the drain pipe 21, and the outlet of the drain pipe 21 is located directly above the drinking trough 22, realizing fixed-point and automatic water supply for laying hens; a second support plate 23 is fixedly connected to the lower surface of the support cylinder 6, and multiple casters 25 are installed on the lower surface of the second support plate 23, which makes the entire feeding equipment easy to move; a handle 24 is fixedly connected to the upper surface of the second support plate 23 near the lower cage 1. The handle 24 is used by the operator to drive the second support plate 23 to move, providing the operator with a force point when pushing the equipment, making it more labor-saving.

[0037] Specifically, the integrated feeding box 17, water pipe 20, drain pipe 21, drinking trough 22, and pull-out manure collection tray 19 efficiently integrate the functions of feeding, drinking, and waste disposal required for laying hen farming, achieving convenient and automated feeding management. Meanwhile, the casters 25 and handles 24 installed at the bottom allow the entire device to be easily moved and rearranged, greatly reducing the labor intensity of daily cleaning and disinfection, and comprehensively improving the practicality of the equipment.

[0038] Working principle: When this feeding equipment is needed, and the cage space needs to be adjusted according to the size of the laying hens, the operator rotates the double-acting screw 13. As the double-acting screw 13 rotates, the two sliders 14 can be driven to move synchronously towards the center or separate to the sides. The sliders 14, through the linkage mechanism composed of the support plate 15 and the hinge block 16, convert the horizontal movement into vertical thrust or pull, which then acts on the crossbar 10 connected to the upper cage 2, thereby driving the support rod 8 to slide smoothly up and down inside the support cylinder 6, realizing the overall lifting and lowering of the upper cage 2. This can accurately provide the most suitable feeding height for laying hens at different growth stages. Furthermore, according to feeding needs, multiple feeding devices can be connected and matched with the extension rod 11 through the support cylinder 6 to achieve the effect of multi-layer feeding.

[0039] Secondly, in daily use, laying hens can eat through the feeding box 17 on the outside of the lower cage 1 and drink through the system consisting of the water pipe 20 and the drinking trough 22 inside the upper cage 2. At the same time, to solve the hygiene problem of stacked rearing, a pull-out manure collection tray 19 is set directly below each upper cage 2. It can efficiently collect the excrement from the upper layer, avoid contaminating the lower cages, and facilitate regular cleaning. When it is necessary to open or close the cage door, the cage door 2 4 can be slid and locked with the buckle 5. At the same time, when it is necessary to move the entire equipment for site cleaning or layout adjustment, the operator can hold the handle 24 and easily push the equipment through the universal wheels 25 at the bottom.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
