A three-dimensional multi-layer composite breeding pen

Abstract

The present invention discloses a three-dimensional multi-layer composite breeding pen. Feces fall from the hollowed-out bottom plate of the upper pen, and an interception component is used to intercept the feces. Eventually, the feces are stacked in a pile on the interception bars. After the feces are dispersed, the contact area with the air is increased, and they can be quickly air-dried. The viscosity of the dried feces is reduced. After the feces pile up too high, the center of gravity shifts and they fall off under the action of air flow or vibration, dropping onto the bottom plate of the lower pen. The dried feces are trampled into debris by the animals in the lower pen and then fall from the hollowed-out bottom plate again, eventually falling onto the collection platform, achieving the purpose of drying and pulverizing feces at low cost. The multi-layer interception bars enable the feces piles to be distributed in the space between the bottom plate and the feces collection platform, and are easily air-dried, solving the problems of strong odor, easy bacteria breeding, and difficult cleaning after the accumulation of a large number of fresh feces. This new type of pen is suitable for large-scale farms.

[0001] The present invention relates to the technical field of aquaculture, and specifically relates to a three-dimensional multi-layer composite aquaculture house. Background Art

[0002] At present, people pay more and more attention to the livestock and poultry aquaculture industry. In the existing technology, in order to improve the land utilization rate, multi-layer houses have emerged. However, when raising poultry and livestock, feces will be produced. The feces in the multi-layer houses need to be uniformly conveyed outside the house by a conveyor belt for centralized treatment, and the cost is relatively high. In the existing technology, in order to meet the emission requirements, the treatment methods of feces usually include drying treatment, aerobic composting, biogas fermentation, chemical treatment, and feed utilization relying on equipment. When large-scale aquaculture is carried out, the above treatment methods are extremely dependent on factors such as equipment, site, and manpower, with high costs, and there are problems of strong odor, easy bacterial growth, and difficult cleaning when a large amount of feces are piled up. Summary of the Invention

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention

[0024] Embodiment 1

[0025] Please refer to Figures 1-6 , the present invention provides a technical solution: a three-dimensional multi-layer composite breeding pen, including a pen 1 and a bottom plate 2 inside it. The number of pens 1 is not less than two layers. As Figure 6 shown, in each layer of the pen 1, a spring auger in the prior art solution is used to provide feed for the animals in the pen 1. A communication channel for animals to move is provided between each layer of the pen 1. Animals can move freely between the upper and lower layers of the pen 1, with a wider activity area, greater exercise volume, stronger resistance, and better quality. The inside of the pen 1 is designed with light shielding, ventilation, and heat preservation, and is provided with lighting facilities, which can be turned on regularly and the lighting intensity can be changed. When raising chickens in the pen 1, the lighting intensity can be reduced during the egg-laying period of the chickens, thereby reducing the visible range of the chickens and avoiding injury to the chickens caused by other chickens pecking at the anus during egg-laying. The bottom plate 2 in each layer of the pen 1 is hollowed out and supported by support columns 6 to be suspended in the air, facilitating the dropping of feces. The space below the bottom plate 2 is a drying chamber 3. A ventilation device 7 is provided on the wall of the drying chamber 3. The fine fecal dust suspended in the air dropped from the upper layer of the pen 1 can be completely discharged to the outside, or the air flow rate can be increased to enhance the air-drying efficiency of the feces. An interception assembly 5 is provided in the drying chamber 3 to prevent the feces from directly falling on the collection platform 4, intercepting and air-drying the feces. The feces that fall after air-drying fall on the bottom plate 2 of the lower layer of the pen 1. The dry feces are trampled into debris by the animals in the lower layer of the pen 1 and then fall again from the hollowed-out bottom plate 2, and finally fall on the collection platform 4 provided below the interception assembly 5 of the bottommost layer of the pen 1. As Figure 5As shown in the figure, baffles are provided above the feeding trough and the drinking device in the pen 1 to prevent fecal debris from falling into them and contaminating the food and water sources. The collection platform 4 is in the shape of a slope, and the dry feces roll down along the slope, facilitating unified collection. A conveying device 8 is provided at the lowest side edge of the slope of the collection platform 4, and the other end of the conveying device 8 extends to the external feces collection point to convey the feces rolling down on the collection platform 4 to the feces collection point;

[0026] The interception component 5 includes two cross beams 52 and an interception layer 51. The two cross beams 52 are installed on the support columns 6, and the interception layer 51 is built on the cross beams 52. The interception layer 51 is composed of at least three equally spaced parallel arrays of interception bars 53. The number of interception layers 51 is at least two and is arranged longitudinally. Between adjacent interception layers 51, the lower interception bars 53 are directly below the gaps between the two upper interception bars 53. Multiple interception layers 51 form a tight interception network. The fresh feces falling from the bottom plate 2 will not directly reach the collection platform 4 and are intercepted by the interception bars 53. The multiple interception bars 53 cause the feces pile to be distributed in the space between the bottom plate 2 and the collection platform 4. After the feces are dispersed, the contact area with the air is increased, and it is easy to be air-dried. The viscosity of the dry feces is reduced. After the feces pile up too high, the center of gravity shifts, and it falls off from the interception bars 53 under the action of air flow or vibration and will not stick to other interception bars 53 anymore, and finally falls on the collection platform 4, achieving the purpose of drying and pulverizing the feces at low cost, solving the problems of strong odor, easy bacterial growth, and difficult cleaning after a large number of fresh feces pile up. The cross section of the interception bar 53 is circular or rectangular. The two ends of the interception bar 53 are arranged on the two cross beams 52 in a swingable or rotatable manner, so that the interception bar 53 swings under the action of air flow, and the dry feces pile on it is more likely to fall off. The interception bar 53 can be externally connected to a power component according to actual conditions to achieve the function of timed flipping. In this way, the interception bar 53 can be flipped at a fixed time to make the feces piled up on it easier to fall off, solving the problem that the feces piled up too high due to climate and other reasons are not easy to fall off, and also solving the problem that the random falling of feces causes disturbance to animals such as chickens. The interception bar 53 is inclined along its axial direction, and the liquid in the feces flows down along the slope of the interception bar 53, further improving the drying speed of the feces. The inclined interception bar 53 makes the center of gravity of the feces pile shift, and it is easier to fall off after drying.

[0027] Embodiment 2

[0028] For feces with high water content, an interception bar 53 with a special structure can be used, such as Figure 3 As shown in the figure, a liquid guide groove 531 is provided on the upper surface of the interception bar 53, and a filter screen 532 is laid on the top of the liquid guide groove 531. The solids in the feces are retained on the filter screen 532, and the liquid flows out along the liquid guide groove 531 for separate treatment.

[0029] Embodiment 3

[0030] When the pen 1 is used for raising poultry such as chickens, as Figure 4 shown, the bottom plate 2 is inclined and an electric wire 22 is provided at the edge of the lowest part. At least two feces blocking protrusions 21 are arranged equidistantly on the bottom plate 2. The feces blocking protrusions 21 are parallel to the edge of the lowest part of the bottom plate 2, preventing the upper feces from rolling and stacking down along the inclined bottom plate 2. Due to the habit of chickens, they like to huddle and stack up when laying eggs, and the chickens in the lower layer will be squeezed to death. The inclined bottom plate 2 causes the center of gravity of the chickens to shift after stacking and slide naturally, so the chickens cannot overlap, avoiding problems such as being crushed to death. The electric wire 22 is used to prevent chickens from gathering in the corner and causing congestion.

[0031] Embodiment 4

[0032] The interception component 5 includes two cross beams 52 and an interception layer 51. The two cross beams 52 are installed on the support columns 6, and the interception layer 51 is built on the cross beams 52. The interception layer 51 is composed of at least three equally spaced parallel arrayed interception bars 53. The interception bars 53 are inclined sheets, as Figure 7 shown. The projection of the interception layer 51 on the horizontal plane has no gaps. The inclined interception bars 53 can also play a role in blocking feces. Dry feces can also fall through the gaps between the interception bars 53, and there is no need to arrange it in a multi-layer structure, which is relatively simple and practical.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
