[0002] In my country, the market demand for poultry such as chickens and ducks has always been at a high level, and the quality of their breeding directly affects people's daily lives.

[0003] Currently, the main farming method for chickens and ducks is intensive and factory-style farming. While this method is suitable for large-scale farming of chickens and ducks, the feeding cost is often high, and the meat quality of chickens and ducks raised in enclosures is often poor. In addition, in the process of some farms, the manure is often discharged directly into ditches, rivers and lakes without treatment, causing a large amount of groundwater pollution.

[0004] Meanwhile, as a major agricultural country and a populous nation, my country has a high demand for crop cultivation. However, long-term and frequent planting has led to a significant decrease in soil fertility, with some land even becoming unsuitable for planting, necessitating urgent improvement of soil fertility. The conventional approach to improving soil fertility is the application of chemical fertilizers. While this method can improve soil fertility to some extent, its capacity is limited, and the cost is relatively high. Utility Model Content

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0033] In the description of this utility model, it should be understood that, unless otherwise explicitly specified and limited, the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] The following, combined Figures 1-3 The structure of the chicken farm according to the preferred embodiment of the present invention is described.

[0038] It should be noted that, in the preferred embodiment, the chicken farm structure is preferably set up on farmland requiring "re-fertilization," that is, utilizing farmland that is currently under intercropping or fallow for chicken farming. This achieves land fallow rotation while ensuring that farmers receive additional income from poultry farming during the fallow period, thus offsetting economic losses caused by land fallow. Furthermore, considering that the breeding cycle of high-quality free-range chickens is 3-6 months, which is relatively short, farmers can flexibly choose the number of poultry rotations and the fallow period as needed, ensuring both planting and breeding efficiency while simultaneously achieving land fallow and re-fertilization.

[0039] like Figures 1-3 As shown, in the preferred embodiment, the chicken farm structure is set on a field, which is enclosed by a closed fence 401 set along the circumference of the field to create a space of a certain area, which serves as a free-range space 4 for raising chickens.

[0040] Meanwhile, at least one chicken coop 402 is set up in the free-range space 4 as a place for the chickens to rest daily. In actual installation, the chicken coop 402 is installed directly on the ground of the field, with a hollow bottom, so that the chickens can rest directly on the ground inside the chicken coop 402 after installation; in this way, the manure produced by the chickens during rest can be directly discharged into the field.

[0041] In actual setup, it is preferable to lay a certain thickness of straw on the floor inside the chicken house 402. This can keep the resting environment of the chickens dry to a certain extent, and the manure produced can seep into the field through the straw.

[0042] More preferably, in actual installation, the ground height at the location where the chicken house 402 is installed is set to be slightly higher than the ground of the surrounding fields. This setting can further prevent waterlogging in the chicken house 402 on rainy days.

[0043] In a preferred embodiment, the chicken coop 402 preferably includes a frame made of tied trees, with a plurality of anchor posts protruding downwards from the bottom of the frame. Accordingly, mounting holes are preferably provided in the ground of the field for each anchor post, so that the frame can be fixed to the ground by inserting the anchor posts into the corresponding mounting holes.

[0044] Meanwhile, in order to improve the heat preservation and insulation performance of the chicken house 402, it is preferable to tie a certain thickness of straw on the inner and / or outer sides of the frame, and to cover the top and outer perimeter of the chicken house 402 with waterproof cloth to ensure the dryness of the straw in the chicken house 402 and improve the waterproof performance of the chicken house 402.

[0045] In addition, to ensure the reliability of the chicken house 402 in the field, it is preferable to set multiple ground nails around its outer perimeter. Each nail is driven into the soil and the top of each nail is fixed to the frame by a connecting rope. The use of ground nails ensures the stability of the chicken house 402 in its setting and fixation.

[0046] Furthermore, in actual setup, at least one area is reserved on the field within the free-range space 4 for the relocation and installation of the chicken coop 402, for example... Figure 1 The two locations shown are examples of this. By reserving these areas and combining them with the detachable installation of chicken coop 402, the location of chicken coop 402 can be changed after a period of use, thereby ensuring the dryness and comfort of the internal environment of chicken coop 402.

[0047] Correspondingly, the area where chicken coop 402 was removed can be restored to a reserved installation location by turning over the soil and leveling it. After the field is dry and leveled, it can wait for the next installation of chicken coop 402.

[0048] For example, in the preferred embodiment, the location of the chicken coop 402 is changed every 2 to 4 weeks. At the same time, for the field area after the chicken coop 402 is moved, it is preferable to carry out land turning and burying treatment, so that the manure that seeps out due to the chicken coop 402 can be buried deep in the soil to ferment and transform, generating organic fertilizer and improving the fertility of the soil.

[0049] In the preferred embodiment, by optimizing the structure and installation method of the chicken coop 402, the reliability and stability of the chicken coop 402 are effectively ensured, the internal environment of the chicken coop 402 is kept dry to a certain extent, the comfort of the chickens resting in the chicken coop 402 is improved, and the quality of chicken farming is further improved. At the same time, by setting up multiple repositioning installation areas, the location of the chicken coop 402 can be changed regularly, which not only ensures the dryness and cleanliness of the chickens' resting area, but also enables re-fertilization treatment in different areas of the field.

[0050] More specifically, such as Figure 1 As shown, multiple trellises 405 are also erected on the field of the free-range space 4. These trellises are preferably made of trees, bamboo and other plants and can be used as climbing objects for vines and form a resting and activity area for the chickens after they have eaten.

[0051] To prevent chickens from pecking at the vines and roots of vine crops and to ensure the reliability of vine crop planting, planting areas are further set up on the inner and / or outer sides of the field of trellis 405.

[0052] For example, in Figure 1 In the preferred embodiment shown, a planting area of ​​a certain length is provided around the outer periphery of the shed 405, and the planting area is located on both sides of the shed 405 and on the side away from the chicken house 402.

[0053] In detail, in the preferred embodiment, the planting area is enclosed by multiple protective partitions 406 fixed to the ground, with openings at the top to allow vines planted within the planting area to extend upwards and climb onto the trellis 405. The protective partitions 406 effectively separate the chickens' activity area from the vine planting area, ensuring the reliability of the vine planting.

[0054] In actual installation, the height of the protective partition 406 above the ground is preferably 0.2~0.5m, and more preferably 0.3m above the ground.

[0055] More preferably, in the preferred embodiment, the sheds 405 provided in the grazing space 4 are preferably multiple, for example... Figure 1 The three shown.

[0056] In addition, in actual setup, the pergola 405 is preferably set up near the fence 401 on the side of the free-range space 4. It is preferably made of trees and bamboo to form a frame, and the height of the pergola 405 is preferably 1.5m to 2.5m. This setup ensures that the vines can climb and grow up far from the ground to avoid being pecked by chickens. On the other hand, it is also easy to match with human height, making it convenient for subsequent harvesting of crops.

[0057] By setting up trellises 405 within the "free-range space 4" of the land, not only can vines be used for climbing, but the top of the trellises 405 can also form a shade canopy, serving as a resting area for chickens. This further increases crop income from the land and optimizes chicken farming conditions. In addition, considering the feeding characteristics of chickens, protective partitions 406 are installed around the roots of the vines, further enhancing the reliability of vine cultivation.

[0058] Furthermore, such as Figure 1As shown, a vegetable plot 3 is preferably arranged circumferentially around the perimeter of the fence 401 for planting vegetables or other crops, making reasonable use of the land's planting function and increasing the additional income of the growers. Furthermore, the circumferential arrangement of the vegetable plot 3 around the perimeter of the fence 401 helps prevent ground manure from being washed away by rainwater in the area inside the fence 401, thus avoiding pollution of the surrounding environment and making reasonable use of the ground fertility generated during the breeding process.

[0059] In addition, considering environmental hygiene during the breeding process, it is preferable to regularly clean or till the ground of the free-range space 4 during actual operations to ensure the cleanliness of the chicken breeding environment. The cleaned-up manure is preferably applied to or buried in the vegetable garden 3 to provide fertilizer for the vegetable garden 3.

[0060] More preferably, in a preferred embodiment, at least one composting pit 403 is provided in the annular area of ​​the vegetable planting plot 3, which is surrounded by a ring wall with its bottom fixed to the ground and its top raised above the ground.

[0061] In actual installation, the ring wall is preferably 0.3-0.5m above the ground, and more preferably 0.4m. Meanwhile, in the composting pit 403 of the preferred embodiment, the main material piled up is cow dung or similar "green grass manure," and it is preferred to cover it with a layer of soil after piling to avoid significant pollution to the surrounding environment during composting and fermentation.

[0062] By placing compost 404 in composting pit 403 for fermentation, earthworms, dung beetles, and other insects can be produced in the compost 404, which can then be used as feed for chickens, enriching their food source. In addition, the compost 404 after fermentation in composting pit 403 can form organic fertilizer with considerable fertility, which can be used as an additive fertilizer in the planting of vine crops or other crops, and can also be used as organic fertilizer for the fields enclosed after the removal of free-range space 4.

[0063] More specifically, in actual setup, the composting pits 403 set up within the rearing space 4 are preferably multiple, for example... Figure 1 The five shown.

[0064] By setting up a composting pit 403 in the vegetable planting area 3 and designing the setting form and composting method of the composting pit 403, the fermentation and preparation of organic fertilizer can be effectively realized, the cleanliness of the planting area can be fully guaranteed, environmental pollution can be reduced, the use of chemical fertilizers can be reduced, and the sustainable development capacity of the environment can be effectively improved.

[0065] Furthermore, in a preferred embodiment, a field ridge 1 is also provided circumferentially around the outer perimeter of the fence 401. This ridge is located on the outer perimeter of the vegetable garden 3 away from the fence 401. The top surface of the field ridge 1 is higher than the ground level of the garden, and a connecting channel 5 is provided on the field ridge 1, communicating with the opening position of the fence 401. Figure 1 As shown in the image.

[0066] In actual setup, the field ridge 1 is 0.5m to 1.0m higher than the field, and a ring-shaped ditch 2 is set between the field ridge 1 and the vegetable planting area 3. The depth of the ring-shaped ditch 2 is preferably 0.4m to 0.8m, which is used to collect rainwater for irrigation of the vegetable planting area 3.

[0067] It is understandable that, in actual setup, water level control holes are installed on the ridge 1 for the ring-shaped ditch 2, and the height of the holes is no higher than the ground of the vegetable field 3, so that the water level in the ring-shaped ditch 2 will never be higher than the ground of the vegetable field 3, thus avoiding large-scale waterlogging in the free-range space 4 during heavy rain and ensuring the reliability of chicken farming.

[0068] Of course, in actual setup, the ground of the free-range space 4 can preferably be slightly higher than the ground of the vegetable garden 3 to avoid water accumulation and flooding in the free-range space 4.

[0069] By setting up vegetable plots 3, circular ditches 2, and field ridges 1 around the perimeter of the fence 401, the overflow of manure produced during chicken farming can be effectively prevented, and the manure produced during chicken farming can be fully utilized to achieve ecological integration of planting and breeding, thereby improving the economic benefits per unit area of ​​land. In addition, the setting of the circular ditches 2 is conducive to collecting rainwater for irrigation in the vegetable plots 3, and also effectively prevents water accumulation in the free-range space 4, ensuring that the free-range space 4 has sufficient drainage capacity and guaranteeing the reliability of chicken farming.

[0070] In addition, during the actual free-range chicken raising process, it is preferable to set up at least one hanging rack (not shown in the figure) in the free-range space 4. The rack preferably includes a support rod or bracket set vertically on the ground, and a vegetable feed basin is suspended on the support rod or bracket 0.2m to 0.5m above the ground. Vegetables harvested from the vegetable garden 3 can be chopped and placed in the vegetable feed basin.

[0071] By suspending the feed in mid-air, the chickens have to jump to eat, and can only peck at a small amount of feed at a time. This effectively avoids the scattering and pollution that may occur when feeding on the ground, saving feed and ensuring the cleanliness of the free-range space.

[0072] Of course, using the suspended feeding method also helps ensure that the chickens have a certain amount of exercise, thereby improving the quality of the chickens' feeding.

[0073] By utilizing the aforementioned chicken farm structure, chicken farming can be effectively achieved, and the process of raising chickens can improve the soil in the fields, enhance soil fertility, and provide support for subsequent planting. It is understandable that, depending on actual needs, after a certain period of chicken farming, the location of the chicken farm structure can be changed. In this case, simply dismantle the fence 401, the shed 405, and the chicken coop 402 and relocate them to another field. The field where these facilities have been removed only needs tilling before replanting crops. Correspondingly, after setting up the aforementioned facilities in the new field, chicken farming can commence, making the entire process simple and convenient.

[0074] The chicken farm structure based on mobile relocation in this utility model is simple in structure and easy to set up. It can effectively realize high-quality chicken breeding and vine planting, achieving ecological integration of planting and breeding. Moreover, the chicken breeding can effectively improve the soil fertility of the field, providing assistance for subsequent planting operations, realizing the sustainable development and utilization of the ecological environment, and has good economic benefits and practical value.

[0075] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
