Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of egg-laying hen breeding cages, specifically an egg-laying hen breeding cage that is easy to feed. Background Technology
[0002] Laying hens are chickens raised specifically to produce eggs. Unlike broiler chickens, the main focus of raising laying hens is to improve egg quality and maintain or increase egg production, rather than improving chicken meat quality. Laying hen cages are needed to provide a standardized growth environment for the hens, while also enabling efficient management, risk control, and resource optimization in the breeding process. In existing laying hen cages, feed is usually placed outside the mesh cage, requiring the hens to stick their heads out to peck at it. This can easily lead to neck feather loss, skin injuries, and the hens getting their heads stuck in the mesh, causing sudden death. Therefore, improvements are needed. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides an easy-to-feed layer hen cage, which solves the problem that when feeding layer hen cages, feed is generally placed outside the mesh cage, requiring the layer hen to stick its head out of the mesh cage to peck at it, which can easily lead to the layer hen's neck feathers falling off, skin injuries, and the layer hen's head getting stuck in the mesh of the cage, causing sudden death.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a hen cage for easy feeding, comprising a wire mesh cage, a rectangular slot provided at the bottom of one side of the inner wall of the wire mesh cage, a feeding rack slidably inserted into the rectangular slot, an installation groove symmetrically provided through one side of the feeding rack, a fixed rod slidably installed through the installation groove, one end of the fixed rod extending through the installation groove to the outside of the feeding rack, a limiting plate fixedly installed on the surface of the fixed rod inside the installation groove, a fixing spring sleeved on the surface of the fixed rod inside the installation groove, a lever fixedly installed on the end of the fixed rod inside the installation groove away from the limiting plate, and the lever extending through the installation groove to the outside of the feeding rack, a cover plate rotatably installed on one side of the top of the wire mesh cage via a pin.
[0005] As a further embodiment of this utility model: the rectangular slot is provided with symmetrical limiting slots on both sides, and the feeding rack is fixedly installed on both sides, with the limiting inserts correspondingly inserted into the limiting slots.
[0006] As a further embodiment of this utility model: one end of the inner wall of the limiting slot is provided with a fixing hole, and the fixing hole is correspondingly inserted into the fixing rod.
[0007] As a further embodiment of this utility model: the cover plate is provided with symmetrical mounting grooves on one side, and mounting rods are fixedly installed inside the mounting grooves.
[0008] As a further embodiment of this utility model: a sliding block is slidably mounted through the surface of the mounting slide rod, and a clamping spring is sleeved on the surface of the mounting slide rod located on one side of the sliding block.
[0009] As a further embodiment of this utility model: an L-shaped card holder is symmetrically fixedly installed on the bottom of the mesh cage on the side away from the rectangular slot, and a fixing strip is fixedly installed on the surface of the mounting slide rod on the outer side of the cover plate, and the fixing strip is engaged with the L-shaped card holder.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-feed layer hen cage features a feeding rack, a fixing rod, and a fixing spring. After placing the hen inside the cage, an appropriate amount of feed is poured into the feeding rack. The feeding rack is then moved to align with the rectangular slot and inserted. Simultaneously, two levers are pushed to pull the fixing rod into the mounting groove, causing the limiting plate to deform the fixing spring inside the mounting groove until the feeding rack is fully inserted into the rectangular slot, aligning the fixing rod with the fixing hole. Releasing the levers allows the fixing spring to push the fixing rod out of the mounting groove and insert it into the corresponding fixing hole, thus securing the feeding rack inside the cage. This facilitates feeding the hen and reduces the risk of neck injuries or sudden death due to the hen's head protruding from the cage.
[0011] This easy-to-feed layer hen cage uses an L-shaped bracket, a cover plate, a clamping spring, and a fixing strip. Pushing the fixing strip causes the sliding block to slide on the mounting slide surface, compressing the clamping spring and deforming it. At the same time, the cover plate rotates to cover one side of the cage until the fixing strip aligns with the L-shaped bracket. Releasing the fixing strip allows the clamping spring to rebound, lifting the sliding block and causing the fixing strip to engage inside the L-shaped bracket. This secures the cover plate to one side of the cage, ensuring that it cannot be easily rotated or opened. Attached Figure Description

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0014] like Figure 1-4 As shown, this utility model provides a technical solution: a hen cage for easy feeding, including a wire mesh cage 1. A rectangular slot 2 is provided at the bottom of one side of the inner wall of the wire mesh cage 1. A feeding rack 5 is slidably inserted into the rectangular slot 2. Limiting slots 3 are symmetrically provided on both sides of the rectangular slot 2. Limiting strips 6 are fixedly installed on both sides of the feeding rack 5, and the limiting strips 6 are correspondingly inserted into the limiting slots 3. By providing the limiting strips 6, the feeding rack 5 is inserted into the rectangular slot 2, so that the limiting strips 6 are locked into the corresponding limiting slots 3, ensuring that the feeding rack 5 is fixed inside the rectangular slot 2 without misalignment or displacement.
[0015] The feeding rack 5 has a symmetrical mounting groove 7 running through one side. A fixing rod 8 is slidably installed inside the mounting groove 7, and one end of the fixing rod 8 extends through the mounting groove 7 to the outside of the feeding rack 5. One end of the inner wall of the limiting slot 3 has a fixing hole 4, and the fixing hole 4 is inserted into the fixing rod 8. Because the feeding rack 5 is provided, the fixing rod 8 extends out of the mounting groove 7 and inserts into the corresponding fixing hole 4, thereby clamping and fixing the feeding rack 5 inside the rectangular slot 2.
[0016] A limiting plate 9 is fixedly installed on one end of the fixed insertion rod 8 inside the mounting groove 7. A fixing spring 10 is sleeved on the surface of the fixed insertion rod 8 inside the mounting groove 7. A lever 11 is fixedly installed on the end of the fixed insertion rod 8 inside the mounting groove 7 away from the limiting plate 9. The lever 11 extends through the mounting groove 7 to the outside of the feeding rack 5. With the fixed spring 10, after the feeding rack 5 is inserted into the rectangular slot 2, the lever 11 is released. Under the rebound action of the fixed spring 10, the limiting plate 9 is pushed up and slides inside the mounting groove 7, which drives the fixed insertion rod 8 to push out of the mounting groove 7 and insert into the corresponding fixing hole 4 to lock and fix the feeding rack 5. A cover plate 13 is rotatably mounted on one side of the top of the wire mesh cage 1 via a pin. A mounting groove 14 is symmetrically provided on one side of the cover plate 13, and a mounting rod 15 is fixedly mounted inside the mounting groove 14. A sliding block 16 is slidably mounted through the surface of the mounting rod 15. A clamping spring 17 is sleeved on the surface of the mounting rod 15 located on one side of the sliding block 16. Due to the clamping spring 17, the sliding block 16 is pushed up and slides on the surface of the mounting rod 15 under the rebound action of the clamping spring 17 until it drives the fixing strip 18 to engage with the L-shaped bracket 12, thus clamping and fixing the cover plate 13 to one side of the wire mesh cage 1.
[0017] An L-shaped bracket 12 is symmetrically fixedly installed on the bottom of the wire mesh cage 1 on the side away from the rectangular slot 2. A fixing strip 18 is fixedly installed on the surface of the mounting slide rod 15 on the outer side of the cover plate 13, and the fixing strip 18 is engaged with the L-shaped bracket 12. With the L-shaped bracket 12 provided, the sliding block 16 drives the fixing strip 18 to be engaged into the L-shaped bracket 12, and the fixing strip 18 is clamped and fixed to ensure that the cover plate 13 is fixed on one side of the wire mesh cage 1 and will not easily rotate and open.
[0018] The working principle of this utility model is as follows: After placing the laying hen inside the wire mesh cage 1, rotate the cover plate 13 to cover one side of the wire mesh cage 1. At the same time, push the fixing strip 18 to cause the sliding block 16 to compress the clamping spring 17 and deform it on the surface of the mounting slide rod 15. After the cover plate 13 is pressed against one side of the wire mesh cage 1, the fixing strip 18 is aligned with the L-shaped bracket 12. Release the fixing strip 18 to allow the clamping spring 17 to rebound and lift the sliding block 16, and insert the fixing strip 18 into the L-shaped bracket 12. This fixes the cover plate 13 to one side of the wire mesh cage 1. Pour an appropriate amount of feed onto the top of the feeding rack 5. Move the feeding rack 5 into the rectangular slot 2. At the same time, push the lever 11 to retract the fixing rod 8 into the mounting groove 7 until the feeding rack 5 is fully inserted into the rectangular slot 2. Release the lever 11. Under the rebound of the fixing spring 10, the fixing rod 8 is inserted into the fixing hole 4, fixing the feeding rack 5 inside the rectangular slot 2. This ensures that the feed on the feeding rack 5 is inside the wire mesh cage 1 for easy feeding of the laying hens.
