Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically a pre-fed two-stage welfare cage. Background Technology

[0002] Welfare cages adhere to animal welfare principles, emphasizing "free movement, natural behavioral expression, and a comfortable environment." These cages primarily include activity areas and laying areas, allowing chickens to stretch their wings, jump, take sand baths, and peck at food. Their design references animal welfare standards in the EU and other regions, prohibiting the overcrowding found in traditional stacked cages (e.g., each chicken having only half the size of an A4 sheet of paper for activity). Traditional chicken welfare cages typically present the following technical problems:

[0003] 1. Currently, the activity area and laying area of ​​welfare cages are mainly designed with overlapping layers. This design is simpler to assemble, meaning that the activity area and laying area of ​​the welfare cage are not on the same layer. However, this will cause the laying hens to stay in the activity area or laying area for a long time, and the laying hens cannot adapt to the environment quickly.

[0004] 2. Egg-laying areas in welfare cages are usually equipped with egg-laying boxes, which are lined with straw mats to improve the comfort of the hens. However, to facilitate egg collection, the bottom of the current egg-laying boxes is usually a single, sloping surface. After placing the straw mats, the original sloping angle of the bottom of the egg-laying box will be affected. When the hens lay eggs outside the egg-laying box, the eggs can easily get stuck in the straw mats as they roll along the sloping surface, making it difficult to collect the eggs.

[0005] 3. In order to help laying hens adapt to the environment better, the cage doors of welfare cages are kept open for a period of time to allow the hens to become familiar with the environment. However, the cage doors of the activity area and the laying area in most welfare cages are opened by flipping outwards. Once the cage doors are open, they will occupy a lot of space around the welfare cage, making it difficult for laying hens to enter or leave the activity area or the laying area. Utility Model Content

[0006] The first technical problem this invention aims to solve is to provide a pre-fostering, two-stage welfare cage in which the activity area and the egg-laying area are on the same layer and interconnected.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pre-fed two-stage welfare cage, comprising multiple enclosed breeding layers distributed from top to bottom;

[0009] Each breeding layer consists of two sets of breeding cages, which are symmetrically distributed. The breeding cages have interconnected egg-laying areas and activity areas, and each of the egg-laying areas and activity areas is equipped with cage doors that can be opened or closed.

[0010] By adopting the above scheme, the pre-fostering two-stage welfare cage, through the design of the egg-laying area and the activity area being on the same layer and interconnected, allows the laying hens to move back and forth between the activity area and the egg-laying area, avoiding the laying hens staying in the activity area or the egg-laying area for a long time. This ensures that the laying hens can quickly adapt to the environment and grow more comfortably in this environment.

[0011] In a preferred embodiment of a pre-fed two-stage welfare cage, the two sets of cages in each breeding layer are symmetrically distributed.

[0012] By adopting the above scheme, in order to reduce the difficulty of assembling the breeding layers, a mirror-symmetrical distribution method is adopted, which is easy to assemble and suitable for welfare cages with three or fewer breeding layers.

[0013] In a preferred embodiment of a pre-rearing two-stage welfare cage, the two sets of rearing cages in each rearing layer are distributed in a symmetrical manner.

[0014] By adopting the above scheme, in order to make the breeding layer more stable, a symmetrical distribution method is adopted, that is, a staggered distribution with the center of gravity located in the middle, which has higher stability and is suitable for welfare cages with three or more breeding layers.

[0015] The second technical problem this invention aims to solve is to provide a pre-fostering, two-stage welfare cage with a threshold-free bottom mesh to facilitate the smooth entry of eggs into the egg pack.

[0016] To achieve the above objectives, the present invention adopts the following technical solution:

[0017] Based on the above scheme, laying boxes are installed in the laying area, and a shared egg conveyor belt is provided below the laying boxes of the two sets of breeding cages. The front and rear of the laying box have entrances and exits respectively. A rotating flap is installed at the entrance to allow the hens to pass through, and a rotating flap is installed at the exit to allow the eggs to pass through. An inclined protective cover is fixed above the egg conveyor belt. The bottom mesh of the laying area is an inclined mesh sloping towards the egg conveyor belt; this inclined mesh leaves a downward trough when entering the laying box, and a straw mat is laid inside the laying box within the trough. At this point, there is no height difference between the bottom mesh outside the laying box and the straw mat inside the laying box.

[0018] By adopting the above solution, in order to ensure that the eggs roll smoothly into the egg belt, a downward sinking groove is left when entering the laying box. After laying the straw mat, there will be no height difference between the bottom net outside the laying box and the straw mat inside the laying box. At this time, even if the laying hen lays eggs outside the laying box, the eggs will not be stuck at the straw mat, ensuring that the eggs enter the egg belt smoothly.

[0019] The third technical problem this utility model aims to solve is to provide a pre-fed, two-stage welfare cage that does not take up space when the folding mesh door is fully opened.

[0020] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] Based on the above scheme, the cage door is designed as two folding mesh doors that flip up and down. After the two folding mesh doors are flipped up, they can be hung and fixed by hooks, and the cage door is in a fully open state.

[0022] By adopting the above scheme, in the first stage (initial stage) of the welfare cage, the cage door is fully opened, allowing the laying hens to enter and exit freely, thus solving the problem of newly transferred laying hens not adapting to the welfare cage; once the laying hens have fully adapted to the environment, the second stage begins, in which the cage door can be completely closed, and the laying hens grow entirely in the welfare cage.

[0023] In a preferred embodiment of a pre-fostering two-stage welfare cage, the bottom net of the egg-laying area and the bottom net of the activity area are aligned flat without steps, and a bracket is installed at the bottom of the gap between the bottom net of the egg-laying area and the bottom net of the activity area for support.

[0024] By adopting the above solution, the problem of inconsistent feeding height of laying hens can be solved. Since the entire bottom net is flat and aligned, it is easy to install feed troughs, which can solve the problem of inconsistent feeding height of laying hens. Moreover, laying hens are less likely to be injured when moving between the laying area and the activity area.

[0025] The beneficial effects of this utility model are:

[0026] 1. This pre-fostering dual-stage welfare cage, through its design of having the laying area and the activity area on the same layer and interconnected, allows laying hens to move back and forth between the activity area and the laying area, avoiding laying hens staying in the activity area or the laying area for a long time. This ensures that laying hens can quickly adapt to the environment and grow more comfortably in this environment.

[0027] 2. To ensure that the eggs roll smoothly into the egg belt, a downward sinking groove is left when entering the laying box. After the straw mat is laid, there will be no height difference between the bottom net outside the laying box and the straw mat inside the laying box. At this time, even if the laying hen lays the egg outside the laying box, the egg will not be stuck at the straw mat, ensuring that the egg enters the egg belt smoothly.

[0028] 3. In the first stage (early stage) of the welfare cage, the cage door is fully opened, allowing the laying hens to enter and exit freely, thus solving the problem of newly transferred laying hens not adapting to the welfare cage; once the laying hens have fully adapted to the environment, the second stage begins, where the cage door can be completely closed, and the laying hens grow entirely in the welfare cage.

[0029] 4. To solve the problem of inconsistent feeding height of laying hens, the entire bottom mesh is flat and aligned, making it easy to install feed troughs. This solves the problem of inconsistent feeding height of laying hens, and also makes it less likely for laying hens to get injured when moving between the laying area and the activity area.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1 to 3As shown, a pre-fostering two-stage welfare cage is provided for raising laying hens, specifically comprising multiple enclosed rearing layers 1 distributed from top to bottom, wherein... Figure 1 The cage consists of three enclosed rearing layers 1. Each rearing layer 1 comprises two sets of rearing cages, symmetrically distributed. Each cage has an interconnected laying area 2 and an activity area 3, each equipped with a cage door 4 that can be opened or closed. This pre-rearing, two-stage welfare cage, by having the laying area 2 and activity area 3 on the same layer and interconnected, allows the hens to move freely between the two areas. This prevents the hens from spending excessive time confined to either the activity area 3 or the laying area 2, ensuring they adapt quickly to the environment and grow more comfortably.

[0042] Continue as Figures 1 to 3 As shown, the two sets of breeding cages in each breeding layer 1 are arranged in a symmetrical or point-symmetrical manner, wherein... Figures 1 to 3 The first breeding layer is arranged in a mirror-symmetrical distribution. To reduce the difficulty of assembling the first breeding layer, a mirror-symmetrical distribution is adopted, which is easy to assemble and suitable for welfare cages with three or fewer breeding layers. To make the first breeding layer more stable, a mirror-symmetrical distribution is adopted, which is staggered front and back, with the center of gravity located in the middle, resulting in higher stability and suitable for welfare cages with three or more breeding layers.

[0043] like Figures 4 to 5 As shown, based on the above scheme, laying boxes 5 are installed in the laying area 2, and a shared egg belt 6 is provided below the laying boxes 5 of the two sets of breeding cages. The laying boxes 5 have entrances and exits at the front and rear, respectively. A flap 7, allowing hens to pass through, is rotatably installed at the entrance, and a flap 8, allowing eggs to pass through, is rotatably installed at the exit. An inclined protective cover 9 is fixed above the egg belt 6. The bottom mesh of the laying area 2 is an inclined mesh sloping towards the egg belt 6; this inclined mesh leaves a downward sinkhole 10 when entering the laying box 5. The laying box 5 is lined with straw mats located within the sinkhole 10. The straw mats are hidden in the figure, so there is no height difference between the bottom mesh outside the laying box 5 and the straw mats inside the laying box 5. To ensure that the eggs roll smoothly into the egg belt 6, a downward sinkhole 10 is provided when entering the laying box 5. After the straw mat is laid, there will be no height difference between the bottom net outside the laying box 5 and the straw mat inside the laying box 5. At this time, even if the laying hen lays the egg outside the laying box 5, the egg will not be stuck at the straw mat, ensuring that the egg enters the egg belt 6 smoothly.

[0044] like Figure 6As shown, based on the above scheme, the cage door 4 is designed as two folding mesh doors that flip up and down. When flipped up, the two folding mesh doors can be suspended and fixed by hooks 11, at which point the cage door 4 is in a fully open state. In the first stage (early stage) of the welfare cage, by fully opening the cage door 4, the laying hens can freely enter and exit, thus solving the problem of newly transferred laying hens not adapting to the welfare cage. Once the laying hens have fully adapted to the environment, the second stage begins, where the cage door 4 can be completely closed, and the laying hens grow entirely within the welfare cage.

[0045] like Figures 7 to 8 As shown, the bottom netting of laying area 2 and the bottom netting of activity area 3 are aligned smoothly and without steps. A bracket 12 is installed at the bottom of the gap between the bottom netting of laying area 2 and the bottom netting of activity area 3 for support. Of course, the bottom netting of laying area 2 and the bottom netting of activity area 3 can also be laid as a single piece. To solve the problem of inconsistent feeding height of laying hens, the flat and aligned bottom netting facilitates the installation of feed troughs, thus solving the problem of inconsistent feeding height of laying hens. Moreover, laying hens are less likely to be injured when moving between laying area 2 and activity area 3.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
