Description

Technical Field

[0001] The utility model relates to the field of livestock and poultry excrement treatment, in particular to a manure cleaning system. Background Art

[0002] As an indispensable part of modern animal husbandry, the core function of the manure cleaning system is to efficiently collect and centrally process the excrement produced by livestock and poultry, aiming to reduce the environmental pollution burden caused by these excrements and explore the possibility of their resource utilization. In the existing technical system, a common design scheme of the manure cleaning system is to deploy a plurality of excrement collection funnels at the bottom of each layer of the breeding room. These funnels are responsible for capturing and initially collecting the excrement produced by the livestock and poultry on the same layer. Subsequently, the excrement on the same layer is guided into a shared horizontal pipeline through its respective funnel, realizing the initial concentration of the excrement within the layer. Further, the excrement in each layer of the horizontal pipeline is then uniformly converged into the vertical pipeline, and finally, the vertical pipeline uniformly transports it to the collection pool for subsequent processing.

[0003] However, this design exposes some significant defects and deficiencies in practical applications. Specifically, when the breeding density on the same layer is relatively high, resulting in a significant increase in the amount of excrement and the number of funnels, the flow rate and concentration of excrement in the horizontal pipeline will increase sharply. In addition, if foreign objects with relatively large particles (such as feed residues, stones, etc.) are accidentally mixed into the excrement, the accumulation of these foreign objects in the pipeline will greatly increase the risk of pipeline blockage. Once the pipeline is blocked, it will not only affect the normal collection and discharge efficiency of excrement, but also may cause secondary pollution to the breeding environment, and even threaten the health and safety of livestock and poultry.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

Detailed Embodiment

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0032] In the existing manure cleaning system, a funnel for collecting excrement is provided at the lower end of each layer of breeding rooms. The excrement collected by each funnel on the same layer converges into a horizontal pipeline, and the horizontal pipelines of each layer then converge into a vertical pipeline. The excrement is then centrally discharged into a collection pool through the vertical pipeline. The defects and deficiencies of this design are that when there are a large number of excrement and funnels on the same layer, or when foreign objects are mixed into the excrement, transporting the excrement only through one horizontal pipeline and one vertical pipeline is likely to cause pipeline blockage and affect the normal collection work.

[0033] To solve the above technical problems, this embodiment provides a manure cleaning system. Please refer to Figures 1 to 5 as shown in Figure 1 which is a schematic diagram of the manure cleaning system in the embodiment, Figure 2 and this is a perspective view of the manure cleaning system in the embodiment, Figure 3 This is Figure 2 a side view of Figure 4 and this is a top view of the funnel in the embodiment.

[0034] The manure cleaning system of this embodiment, as Figure 1 shown, includes: a bracket 1, a funnel 2, an inclined pipe 3, a confluence pipe 4, and a collection pool 5.

[0035] The bracket 1 is relatively fixed to the floor slab 6 and serves as the foundation for installing the funnel 2.

[0036] The funnel 2, as Figure 1 shown, is used to collect the excrement of livestock and poultry. A number of funnels 2 are arranged along the first direction on the bracket 1 and are sequentially divided into two groups of funnels 2 along the first direction; the first direction can be set to be horizontally transverse or longitudinal according to needs.

[0037] The inclined pipe 3, as Figure 1 shown, extends obliquely downward along the first direction, and there are two inclined pipes 3 provided on the bracket 1. The two inclined pipes 3 are respectively connected to the two groups of funnels 2 through pipelines; it can be understood that the inclined pipe 3 has a certain slope, so that the excrement can be automatically transported forward by its own weight when passing through the inclined pipe 3.

[0038] The confluence pipe 4, as Figure 1 shown, has a quantity of two and is respectively connected to the lower ends of the two inclined pipes 3 at the horizontal position, and is used to transport the excrement in the inclined pipe 3 to the collection pool 5.

[0039] The manure cleaning system of the above technical solution significantly improves the operating efficiency and stability of the system during operation by innovatively adopting the design of grouped collection and shunt discharge. Specifically, the collection funnels 2 of livestock and poultry excreta are divided into two groups, and each group of funnels 2 is independently connected to an inclined pipe 3. Then, the excreta are guided to the collection pool 5 through two parallel confluence pipes 4 for centralized treatment and utilization. This design effectively disperses the excreta flow in a single pipe compared with the traditional mode that only relies on single horizontal and vertical pipe transportation, significantly reducing the risk of pipe blockage caused by excessive excreta concentration or foreign matter mixing. In addition, the shunt discharge mechanism helps to maintain the hydrodynamic balance in the pipe, ensuring that the excreta can be smoothly and efficiently transported to the collection pool 5, thereby improving the operating efficiency and reliability of the entire manure cleaning system and providing strong support for the improvement of the livestock and poultry breeding environment and resource utilization.

[0040] Exemplarily, the bracket 1 can be supported on the floor slab 6 and can be fixed to the floor slab 6 by means of bolt connection or the like.

[0041] Exemplarily, the funnel 2 is connected to the bracket 1 by means of welding, bolt connection or the like. Positioning holes for sleeving the funnel 2 can be provided on the bracket 1 to improve the stability of the funnel 2.

[0042] To improve the connection stability of the funnel 2, refer to Figure 2 and Figure 3 As shown, the funnel 2 includes a funnel 2 main body and an outer edge 20 provided at the opening edge of the funnel 2 main body; at least two groups of funnels 2 are provided along the second direction on the bracket 1, and the adjacent outer edges 20 of the two groups of funnels 2 are stacked on each other. The funnels 2 in the prior art are made of plastic pressing, and additional support rods or support frames need to be provided during their installation to support and fix the funnels 2. The edge of the funnel 2 in this embodiment has an extended frame, that is, the outer edge 20, and they can be directly overlapped when placing the funnels 2. This method reduces the additional cost of the bracket 1, effectively strengthens the installation of the funnel 2, and improves the stability of the overall structure; at the same time, when the funnel 2 is damaged, the stacked structure is convenient for quick disassembly and replacement.

[0043] Exemplarily, the funnel 2 is a quadrangular pyramid, the conical bottom surface of the funnel 2 faces upward to collect excreta, and a flange pipe fitting is welded to the conical tip of the funnel 2; there is no planar structure at the buffer opening of the funnel 2, which will not cause waste accumulation and reduce the generation of ammonia; the funnel 2 is made of stainless steel, with improved surface smoothness, which is conducive to the falling and collection of waste, further reducing the generation of ammonia, and the funnel 2 can be corrosion-resistant and more durable.

[0044] To clean the excreta in time and avoid the accumulation of excreta, refer to Figure 1As shown in the figure, the manure cleaning system includes a grille plate 7 provided at the upper end of the funnel 2 and a spraying device 8 located above the grille plate 7. An ammonia sensor 9 is provided between the grille plate 7 and the funnel 2. The ammonia sensor 9 is used to detect the ammonia content in the area of the funnel 2 and feed back the ammonia content to the spraying device 8. When the ammonia content reaches a preset value, the spraying device 8 performs a spraying operation on the grille plate 7. In this embodiment, the grille plate 7 can block larger foreign objects and excrement. By detecting the ammonia content in the area of the funnel 2, the quantity of excrement is monitored from the side. When the ammonia content reaches the preset value, the spraying device 8 sprays the grille plate 7 to wash the excrement on the grille plate 7 into the funnel 2.

[0045] Exemplarily, the above-mentioned spraying device 8 is an existing automatic spraying device 8. When the ammonia content reaches the preset value, it controls the opening of the spraying pipeline through an electronic valve to perform a spraying operation on the grille plate 7.

[0046] Exemplarily, the ammonia sensor 9 is fixed to the lower end of the grille plate 7 by bolts or buckles, and its circuit is led out through a waterproof pipeline at the lower end of the grille plate 7.

[0047] Exemplarily, the number of ammonia sensors 9 can be selected according to the number of funnels 2. For example, one ammonia sensor 9 is provided for every four funnels 2.

[0048] Since the quantity of excrement is not the same in each area, in order to perform separate cleaning on the areas with more excrement, refer to Figure 1As shown, the manure cleaning system includes a grid plate 7 and a spray device 8. The grid plate 7 is arranged at the grid plate 7 at the upper end of the funnel 2. The spray device 8 is provided with two groups corresponding to the funnel 2, and is used to spray the grid plates 7 above the two groups of funnels 2 respectively; an ammonia sensor 9 is provided in the two oblique pipes 3 or the two confluence pipes 4, and the ammonia sensor 9 is used to detect the ammonia content in the oblique pipes 3 or the confluence pipes 4, and feed back the ammonia content to the spray device 8 of the same group; when the ammonia content reaches a preset value, the spray device 8 sprays the funnel 2 of the same group. The manure cleaning system of this embodiment cleverly combines the grid plate 7, the spray device 8 and the ammonia sensor 9. This design is intended to achieve intelligent regional management and cleaning of excrement. First, a grille plate 7 is arranged at the upper end of each funnel 2, and its function is to preliminarily separate the livestock and poultry activity area so that the excrement can fall into the corresponding funnel 2 in a relatively concentrated manner. This not only helps to reduce the spread of excrement in the breeding area, but also facilitates subsequent collection and treatment; then, the spray device 8 is arranged in two groups, and each group of spray devices 8 is specifically responsible for corresponding to a group of grille plates 7 above the funnel 2. This grouped spraying design allows the system to flexibly select the cleaning area according to actual needs, thereby realizing the effective utilization of resources; what is particularly critical is that the manure cleaning system of this embodiment has an ammonia sensor 9 installed in two oblique pipes 3 or two conduits 4. Ammonia is one of the common gases in livestock and poultry excrement, and its content can indirectly reflect the accumulation and decomposition of excrement. The ammonia sensor 9 can monitor the ammonia content in the pipeline in real time and feed this information back to the spray device 8 in the same group. When the ammonia content in the pipeline reaches a preset threshold, it means that the excrement in this area may be large or has begun to significantly decompose and produce ammonia. At this time, the corresponding spray device 8 will be activated to spray the grid plate 7 above the funnel 2 of the same group. The spraying operation can not only directly clean the dirt and residue on the grid plate 7 to reduce its impact on the air quality, but also through the action of water flow, it can prompt the excrement in the funnel 2 to enter the pipeline system faster, thereby accelerating its subsequent collection and treatment process.

[0049] In order to facilitate the unblocking of the manifold 4 when it is blocked, refer to Figure 5 and Figure 6 As shown, Figure 5 is a schematic diagram of a manifold in an embodiment, Figure 6Schematic diagram of the manifold during installation and dredging processes in the embodiment. The manifold 4 includes a first pipe 41, a second pipe 42, a third pipe 43, and a dredging valve 44. The first pipe 41 and the second pipe 42 are coaxial and spaced apart, serving as the main part of the manifold 4. The first pipe 41 and the second pipe 42 are respectively provided with a forward thread 401 and a reverse thread 402 at opposite ends. The dredging valve 44 is used to open and close the third pipe 43. Threads adapted to the forward thread 401 and the reverse thread 402 are respectively provided at both ends of the third pipe 43. One end of the third pipe 43 is connected to the first pipe 41 through the forward thread 401, and the other end is connected to the second pipe 42 through the reverse thread 402. The lengths of the forward thread 401 and the reverse thread 402 are greater than the length required for connecting to the third pipe 43. That is, when the third pipe 43 is disengaged from the threaded connection with the first pipe 41, it can still maintain a threaded connection state with the second pipe 42, and vice versa. During installation, the third pipe 43 is pre-threaded to the first pipe 41. When connecting the second pipe 42, it is rotated in the direction of the second pipe 42 until it is threadedly connected to the second pipe 42, realizing the connection between the first pipe 41 and the second pipe 42 through the third pipe 43. The valve in the third pipe 43 can output from the first pipe 41 and input to the second pipe 42 during normal excretion transportation. When the second pipe 42 is blocked, the third pipe 43 can be screwed in the direction of the first pipe 41, so that while opening the second pipe 42, it can close the first pipe 41 through the dredging valve 44 to prevent excrement from flowing out, thus improving the convenience of pipeline dredging operations.

[0050] Exemplarily, the dredging valve 44 is a manual dredging valve 44, and the manual dredging valve 44 can be any one of a gate valve, a ball valve, or a butterfly valve.

[0051] Exemplarily, the inclined pipe 3 can also use the structures of the above-mentioned first pipe 41, second pipe 42, third pipe 43, and dredging valve 44 as needed to control the excretion transportation and improve the convenience of dredging operations.

[0052] For ventilating and cooling the poultry and livestock houses, refer to Figure 1 As shown, the manure cleaning system further includes a fan 10. The fan 10 is used to blow air laterally into the space between the floor slabs 6, that is, the poultry and livestock houses, to achieve a ventilation effect. At the same time, the fan 10 can be used together with the spraying device 8 to further improve the cooling effect.
