Description

Technical Field

[0001] This utility model belongs to the field of poultry farming, and in particular relates to a mobile free-range chicken house. Background Technology

[0002] In poultry farming, chickens are typically kept in small cages. However, compared to free-range chickens, these chickens have a smaller range of movement and are mostly fed commercial feed, resulting in coarser meat fibers, poorer taste, and lower nutritional content. Meanwhile, with increasingly demanding consumer expectations, cageless production is becoming an inevitable trend in poultry production, necessitating improvements in poultry house design. Currently, there are chicken houses built directly on grasslands, confining chickens within a certain area. Besides a fixed supply of feed, the chickens can forage for grass seeds and insects, increasing their range of movement and allowing them to freely forage in the wild. This allows them to utilize their natural instincts, maximizing their welfare and increasing productivity. In production systems using this design, chickens are often freely dispersed, satisfying their various needs such as eating, drinking, scratching, sand bathing, and resting—all natural behaviors that improve the nutritional value and taste of the meat. Chicken coops also provide a good living environment for chickens, which is not only conducive to their healthy growth and reproduction, but also reduces the labor required to clean the coops. At the same time, the droppings produced by the chickens are beneficial to the ecological restoration of the grassland. In order to protect the grassland and ensure that the chickens can obtain food stably within the enclosure, the coops are equipped with wheels at the bottom. Every once in a while, the coops will be moved to an adjacent location, so that the previous grassland environment can be naturally repaired, realizing the recycling of resources and the protection of the ecological environment.

[0003] However, before moving existing chicken houses, it is necessary to lift the fences fixed to the ground and close the ventilation curtains at the bottom of the chicken house to prevent chickens from running out of the enclosure. However, all of the above operations need to be carried out manually, and the gap between lifting the fences and lowering the ventilation curtains can easily cause chickens to run out. Therefore, before each move, it is usually necessary for multiple people to work together to drive the chickens and operate the equipment. Utility Model Content

[0004] In view of this, the present invention aims to provide a mobile free-range chicken house to reduce the preparation work before moving the chicken house.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A mobile free-range chicken coop includes a frame and a canopy connected to the frame. Multiple barrier nets are installed along the edge of the bottom of the coop, and each barrier net can move vertically. When the barrier net is at its lower limit position, its bottom can touch the ground. A ventilation curtain is installed at the bottom of the canopy, and its bottom can contact the ground. A fixing hook is provided on the top of the barrier net facing the ventilation curtain, and the bottom of the ventilation curtain can be rolled up and rest on the fixing hook. A release tab is also provided on the side of the fixing hook. The bottom end of the release tab has a guide surface inclined away from the barrier net on the side facing the ventilation curtain. When the barrier net moves upward, the rolled-up portion of the bottom of the ventilation curtain can contact the guide surface and separate from the fixing hook.

[0007] Furthermore, ground stakes extend vertically downwards from the bottom of the barrier net.

[0008] Furthermore, each barrier net has multiple ground spikes, and a barrier plate is provided between every two adjacent ground spikes.

[0009] Furthermore, two barrier plates are provided between each pair of adjacent ground spikes, and the barrier plates are all straight triangles, with the two straight sides of the barrier plates connected to the sidewalls of the ground spikes and the bottom of the barrier net.

[0010] Furthermore, the frame includes multiple vertical beams, and each pair of adjacent vertical beams has a sliding track on their opposite sidewalls, with the two sides of the barrier net placed within the sliding track.

[0011] Furthermore, the bottom edge of the ventilation curtain is wrapped with a counterweight chain or counterweight rod, and the counterweight chain can abut against the side wall of the ground nail.

[0012] Furthermore, the ventilation curtain is placed inside the barrier net.

[0013] Furthermore, the fixing hook includes a supporting part and a limiting part, with an obtuse angle between the supporting part and the limiting part.

[0014] Furthermore, the frame is provided with a crossbeam, a direct drive motor is fixed on the crossbeam, and the barrier net is connected to the direct drive motor.

[0015] Compared with existing technologies, the mobile free-range chicken coop described in this utility model has the following advantages:

[0016] This utility model uses a method of fixing the fixing hook to the barrier net, in conjunction with the guide surface, so that when the chicken house is moved, the upward-lifting barrier net drives the ventilation curtain to contact the guide surface, so that the ventilation curtain automatically falls before the chicken house is moved, thereby preventing the chickens inside the chicken house from escaping without affecting the movement of the chicken house.

[0017] By installing ground nails under the barrier net, the chicken house can automatically fix its position after moving to a new location, thus improving its wind resistance.

[0018] A barrier plate is installed below the barrier net to prevent chickens from escaping through the gaps between the ground nails when the barrier plate initially moves upward and the ventilation curtain has not yet fallen or has not fallen to the bottom. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] The mobile free-range chicken coop of this utility model includes a frame 1 and a canopy 2 connected to the frame 1. Specifically, the canopy 2 can be connected to the frame 1 by means of adhesive, binding, sewing, etc. The frame 1 is provided with wheels on its edges. The wheels are driven by a motor or other power source, and the specific walking structure is existing technology and will not be described in detail here. Multiple barrier nets 3 are provided along the edge of the bottom of the chicken coop, and each barrier net 3 can move vertically. When the barrier net 3 is placed at its lower limit position, the bottom of the barrier net 3 can touch the ground to prevent the chickens from leaving the area enclosed by the chicken coop. In this embodiment, the frame 1 includes multiple vertical beams 11, and a slide rail 14 is provided on the opposite side wall of every two adjacent vertical beams 11. The two sides of the barrier net 3 are respectively placed in the slide rail 14. At least one horizontal beam 12 is provided between each pair of adjacent vertical beams 11. A fixed platform 13 is provided on the horizontal beam 12. A drive motor is fixed on the fixed platform 13. The drive motor can drive the barrier net 3 to move along the height direction by means of winching, lifting or other methods. In this embodiment, the drive motor is a rotary direct drive motor 4. A screw 31 extends vertically upward from the top of the barrier net 3. The screw 31 is screwed to the screw ring in the rotary direct drive motor 4, so that the rotary direct drive motor 4 can lift the barrier net 3.

[0030] The bottom of the tarpaulin 2 is equipped with a ventilation curtain 21, which is integrally set with the tarpaulin. The top of the ventilation curtain 21 is fixed to the frame 1, and the bottom can be rolled up or swung under external force. Optionally, two adjacent ventilation curtains 21 are cut together to form a slit, and the ventilation curtain 21 corresponds to the barrier net 3. The bottom of the ventilation curtain 21 can contact the ground. When the barrier net 3 is in the upper limit position, the ventilation curtain 21 can also prevent chickens from escaping. At the same time, when the chicken house is moved, the bottom of the ventilation curtain 21 rests on the ground or maintains a small gap with the ground to prevent it from affecting the overall movement of the chicken house. In order to prevent the ventilation curtain 21 from being blown up by the chickens during the movement, which would cause gaps between the ventilation curtains 21 and allow the chickens to escape, a counterweight chain or counterweight rod is provided at the bottom of the ventilation curtain 21. The counterweight chain can be an iron chain or a chain, and the counterweight rod can be a metal rod. The counterweight chain or counterweight rod can be fixed to the bottom of the ventilation curtain 21 by binding, sewing, or other methods.

[0031] The top of the barrier net 3 facing the ventilation curtain 21 is provided with a fixing hook, and the bottom of the ventilation curtain 21 can be rolled up and rest on the fixing hook. A release piece 5 is also provided on the side of the fixing hook. The bottom end of the release piece 5 facing the ventilation curtain 21 has a guide surface 51 that slopes away from the barrier net. When the barrier net 3 moves upward, the rolled-up portion of the bottom of the ventilation curtain 21 can contact the guide surface 51 and separate from the fixing hook. In this embodiment, the top of the release piece 5 is fixed to the crossbeam 12 of the frame 1. Specifically, the fixing hook includes a support part 321 and a limiting part 322, with an obtuse angle between the support part 321 and the limiting part 322. In this embodiment, the support part 321 is horizontally arranged, and the limiting part 322 is formed by the outer end of the support part 321 extending upward at an angle. In this embodiment, the bottom of the ventilation curtain 21 is a chain. When the chicken house is in a fixed state, its middle part can rest on the fixing hook, forming a ventilation opening at the bottom of the ventilation curtain 21 to facilitate ventilation and lighting at the bottom of the chicken house. Optionally, when the bottom of the ventilation curtain 21 is a counterweight rod, there can be multiple fixing hooks. When the barrier net 3 moves upward, the counterweight chain or counterweight rod contacts the guide surface 51 of the release plate 5. When the barrier net 3 continues to move upward, the counterweight chain or counterweight rod is subjected to the squeezing force of the guide surface 51 towards the limiting part 322, causing the part of the counterweight chain or counterweight rod that rests on the fixing hook to move outward, thereby separating the counterweight chain or counterweight rod from the fixing hook. The ventilation curtain 21 falls naturally under the action of gravity, so that the ventilation curtain 21 is lowered at the same time as the barrier net 3 is raised, allowing the chicken house to quickly complete the conversion between the fixed state and the moving state, while saving manpower and resources.

[0032] The bottom of the barrier net 3 extends vertically downwards with ground spikes 33. The displacement distance of the barrier net 3 along the height direction is greater than the length of the ground spikes 33. When the chicken coop is moved, the barrier net 3 falls down, and the ground spikes 33 penetrate the ground, thus fixing the chicken coop. Each barrier net 3 has multiple ground spikes 33, and a barrier plate is provided between every two adjacent ground spikes 33. More specifically, two barrier plates are provided between every two adjacent ground spikes 33, and the barrier plates are straight triangles. The two straight sides of the barrier plates are connected to the side wall of the ground spike 33 and the bottom of the barrier net 3, thereby strengthening the ground spikes 33 and preventing chickens from escaping through the gaps between the ground spikes 33 when the barrier plates initially move upwards and the ventilation curtain 21 has not fallen or has not fallen to the bottom. The ventilation curtain 21 is placed inside the barrier net 3, and the counterweight chain can abut against the side wall of the ground spikes 33, further preventing chickens from rushing out of the ventilation curtain 21 and escaping during the movement. After the chicken coop has been moved and secured, the ventilation curtain 21 can be rolled up manually based on the environment and weather conditions.

[0033] The barrier net 3 has a frame around its edge, and the ground nails 33, barrier plates 34, screws 31 and other structures are respectively fixed on the frame.

[0034] The above description is only a preferred embodiment of the present utility model and is 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 should be included within the protection scope of the present utility model.
