Description

Technical Field

[0001] This invention relates to the field of pig farming technology, specifically to a pig farming shed with automatic manure cleaning system. Background Technology

[0002] Currently, the pig farming industry faces problems of environmental pollution and difficulty in cleaning. Traditional cleaning methods for pig sheds rely on manual cleaning, which is labor-intensive. Furthermore, the humid environment of the pig farm easily breeds bacteria and produces odors, posing a threat to the health of pigs. In order to improve the hygiene of the pig farm environment, many patents have proposed different automatic cleaning solutions.

[0003] Chinese invention patent application CN117158327A discloses an automatic cleaning system for pig manure sheds, including a housing, a bottom trough, a manure conveyor belt, and cleaning liquid and drying gas for cleaning support rods. The system collects and processes manure through the conveyor belt and can clean the support rods, reducing manure residue on the support rods. However, the cleaning method of this design mainly relies on the manure conveyor belt for material transportation, which fails to effectively separate solid and liquid substances, and there is still room for improvement in the sealing and cleaning efficiency during the cleaning process.

[0004] Chinese utility model patent CN212344893U discloses a fully automated and environmentally friendly pig farming equipment system. It uses a chain drive plate device to operate automatically at timed intervals, automatically cleans feces, separates urine from feces, and can adjust the temperature of the breeding house and monitor the body temperature of pigs in a timely manner. However, this design relies on the mechanical operation of chain drive and cleaning device, which is prone to wear and tear during long-term use. In addition, the equipment is complex and has high maintenance costs, making it difficult to meet the stability requirements of large-scale farms.

[0005] While the above design effectively improves the cleanliness of the breeding environment, it still has some limitations. First, the existing manure conveyor belt and chain drive device are relatively simple and fail to effectively separate solid and liquid substances. Moreover, the transmission parts are prone to wear and tear during long-term operation, resulting in frequent maintenance and high costs. Second, although it can clean manure, it fails to effectively prevent secondary pollution of manure during the cleaning process and fails to maintain good sealing throughout the cleaning process, which can easily lead to odor leakage and bacterial spread in the environment.

[0006] This invention proposes a new automatic cleaning solution to address these shortcomings. It employs staggered fixed and lifting comb teeth and an adjustable comb tooth spacing design to achieve effective separation and automatic collection of solid and liquid materials. Through an improved liquid and solid material collection system, as well as temperature and ventilation regulation functions, this invention can better solve the problems of low efficiency, secondary pollution, and high maintenance costs in traditional cleaning methods. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and to propose an automatic manure cleaning pig farm shed to solve the above-mentioned problems.

[0008] The objective of this invention is achieved through the following technical solution: an automatic manure-cleaning pig breeding shed, comprising multiple breeding boxes connected in sequence, each breeding box including fixed combs symmetrically arranged on the left and right, with lifting combs between two fixed combs, the combs on the lifting combs being staggered with the combs on the fixed combs, both the fixed and lifting combs having hollow structures, the hollow parts of the fixed combs being connected to an external hot water circulation system via pipes, the hollow parts of the lifting combs being connected to an external cold water circulation system via pipes, a first enclosure and a second enclosure being snapped onto the top of the fixed combs, the two ends of the lifting combs penetrating the second enclosure, and lifting operating rods being fixedly connected to the penetrating parts, a guide rail symmetrically arranged front and rear being fixedly connected to the bottom of the breeding box, a solid matter collection box being slidably connected between the two guide rails, a liquid matter collection tank being fixedly connected to the bottom of the two guide rails, a base being fixedly connected to the bottom of the liquid matter collection tank, and a solid matter storage box and a liquid matter storage box being fixedly connected to the two ends of the base along the length of the solid matter collection box, respectively.

[0009] The teeth on the fixed comb and the lifting comb are arranged in contact with each other to seal the bottom of the breeding box, and allow the pigs to move freely on the top of the fixed comb and the lifting comb.

[0010] The distance between two adjacent comb teeth on the fixed comb teeth and between two adjacent comb teeth on the lifting comb teeth is smaller than the outer diameter of the pig's hoof on them, so that the pig's hoof will not get stuck between the two comb teeth.

[0011] The lifting control lever is slidably connected to the end of the second enclosure away from the fixed comb teeth, and the top of the lifting control lever is fixedly connected to the second enclosure through a pin.

[0012] The bottom of the solid collection box is slidably connected to the guide rail via a pulley system. The pulley system includes three pulleys, two of which are located at the upper end of the guide rail and the other at the lower end of the guide rail.

[0013] The guide rail bends downwards at the end near the solid matter storage box, allowing the solid matter collection box to flip downwards when it slides to the bend, thus pouring the solid matter on the solid matter collection box into the solid matter storage box.

[0014] The liquid collection tank has a V-shaped cross-section between the solid storage tank and the liquid storage tank. The liquid collection tank is set at an incline, and the end of the liquid collection tank near the liquid storage tank is lower than the end near the solid storage tank.

[0015] The pulley block has a drive motor on one of the pulleys at the upper end of the guide rail to drive the pulley to rotate. The outer end of the breeding box is equipped with a support plate for the breeding personnel to move around.

[0016] When the lifting comb moves downward, the comb teeth on the lifting comb move away from the comb teeth on the fixed comb, causing the feces and dirt at the top of the fixed comb and the lifting comb to fall to the bottom of the fixed comb and the lifting comb under the action of gravity. When the distance between the comb teeth is small, liquid substances flow out from the gaps. When the distance between the comb teeth is large, solid substances fall out from the gaps between the comb teeth.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention achieves automatic cleaning of pig manure by using a staggered arrangement of fixed and lifting comb teeth and an adjustable comb tooth spacing. Liquid and solid matter are automatically separated under gravity and collected into liquid collection tank and solid collection box respectively, which greatly reduces the need for manual intervention, reduces labor intensity, and improves cleaning efficiency.

[0019] 2. The design of the comb tooth spacing takes into full account the outer diameter of the pig's hoof, so that the distance between the comb teeth is smaller than the outer diameter of the pig's hoof, thereby effectively avoiding the problem of the pig's hoof getting stuck when it moves. This design ensures the pig's free movement, reduces the injury or discomfort caused by the comb teeth getting stuck, and improves the safety of the breeding environment.

[0020] 3. This invention adopts an independent design for the liquid collection tank and the solid collection box, which enables the liquid and solid materials to be effectively separated and stored separately. The design of the solid collection box and the liquid collection tank ensures that the two will not mix, avoiding pollution and inconvenience during the treatment process, and improving the cleanliness and hygiene level of sewage management.

[0021] 4. This invention, through the combination of a hot water circulation system and a cold water circulation system, can regulate the temperature inside the breeding shed, ensuring that the temperature is always within a suitable range. In addition, the design of the lifting comb teeth allows the airflow to be adjusted as needed, increasing the ventilation effect in the breeding environment, keeping the air fresh and clean, improving the growth environment of pigs, and reducing the accumulation of odors and harmful gases.

[0022] 5. The design, which combines pulleys and guide rails, allows the solid material collection box to slide smoothly on the guide rails. When it reaches the solid material storage box, it flips over to pour the solid material into the storage box. This design effectively utilizes the principle of gravity, simplifies the process of solid material collection and processing, and improves the convenience of operation and cleaning efficiency.

[0023] 6. Due to the automated cleaning function of this invention, farms no longer need to rely on a large number of manual laborers for cleaning. The equipment automatically completes the separation, cleaning, and storage of solid and liquid materials, which greatly saves labor costs and reduces the omissions and pollution that may occur during manual cleaning, thereby improving the scientific and modern level of aquaculture management.

[0024] 7. This invention features an easy-to-operate pulley system, motor drive, and adjusting rod structure, enabling farmers to conveniently adjust and maintain the equipment. The design of the lifting control rod and enclosure makes equipment adjustment more flexible, allowing users to easily control the movement and height adjustment of the comb teeth as needed, thus improving the operability and ease of maintenance of the equipment.

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that the directional concepts of "left", "right", "up", "down", "front", "back", "inner", and "outer" in the following scheme are all relative directions, and will not be listed one by one here.

[0042] Example 1:

[0043] like Figures 1 to 13 As shown in the figure, this embodiment provides a pig breeding house with automatic manure cleaning, which adopts multiple breeding boxes 1 connected in sequence. Each breeding box consists of fixed comb teeth 1 and lifting comb teeth 2. The fixed comb teeth 1 and lifting comb teeth 2 are combined by staggered configuration and hollow structure to ensure that the manure of pigs can be effectively cleaned during the breeding process.

[0044] The comb teeth on the fixed comb teeth 1 and the lifting comb teeth 2 are arranged in an alternating manner. The hollow part of the comb teeth is connected to the external hot water and cold water circulation system through pipes. Specifically, the fixed comb teeth 1 is connected to the hot water circulation system through pipes, while the lifting comb teeth 2 is connected to the cold water circulation system through pipes. The hot water system helps with cleaning and disinfection, while the cold water system is used to cool down and reduce the temperature burden inside the breeding house.

[0045] The comb teeth on the fixed comb teeth 1 and the lifting comb teeth 2 contact each other and seal the bottom of the breeding box, forming a closed working area. This ensures that the pigs can move around in the area without getting stuck, while preventing manure leakage and enhancing the cleaning effect.

[0046] The top of each breeding box is enclosed by enclosure 3 and enclosure 4. Enclosure 3 and enclosure 4 together ensure the safe movement of pigs in the breeding box. The through parts at both ends of the lifting comb 2 are connected to the lifting operation rod 5, which makes it easy for the operator to adjust the height of the lifting comb 2 as needed to achieve automatic cleaning of manure.

[0047] A guide rail 6 is installed at the bottom of the breeding box. A solid waste collection box 7 is slidably connected to the guide rail 6. The solid waste collection box 7 is slidably connected to the guide rail 6 through a pulley group 13. The pulley group 13 includes three pulleys, two of which are located at the upper end of the guide rail 6 and the other pulley is located at the lower end of the guide rail 6, so that the solid waste collection box 7 can move along the guide rail 6, which facilitates the collection and treatment of solid waste.

[0048] The solid material collection tank 8 is located at the bottom of the guide rail 6 and is connected to the liquid material collection tank 8. The liquid material collection tank 8 adopts a V-shaped structure and is set at an angle, with the end closer to the liquid material storage tank 11 being lower, to ensure that the liquid material can flow into the liquid material storage tank 11.

[0049] The liquid collection tank 8, with its inclined design and V-shaped structure, can effectively guide the liquid to the liquid storage tank 11. This design ensures that the liquid does not accumulate and avoids the generation of odors or the growth of bacteria.

[0050] The working principle of this embodiment is as follows:

[0051] When the pigs move around in the breeding box 1, the fixed comb teeth 1 and the lifting comb teeth 2 are interlocked and seal the bottom of the breeding box. The pigs collect their feces and waste under the comb teeth through contact with them.

[0052] By operating the lifting lever 5 to lift the comb teeth 2, the distance between the comb teeth can be adjusted, so that solid and liquid substances can fall or flow to the liquid collection tank 8 and the solid collection box 7 according to the change in the distance between the comb teeth.

[0053] The solid matter collection box 7 slides on the guide rail 6 via the pulley group 13. When it approaches the solid matter storage box 10, the solid matter falls into the solid matter storage box 10 through the flipping mechanism.

[0054] The liquid collection tank 8 guides the liquid to the liquid storage tank 11 through its inclined design. This process avoids water accumulation or pollution, and maintains the cleanliness of the breeding environment.

[0055] Through a hot and cold water circulation system, the comb teeth on the fixed comb teeth 1 and the rising comb teeth 2 are kept clean, reducing the generation of bacteria and odors.

[0056] The structural design in this embodiment enables automatic cleaning of manure and waste inside the breeding box, improving the hygiene conditions of the pig breeding environment and reducing the amount of manual cleaning work.

[0057] The staggered arrangement and sealing effect of the fixed comb teeth 1 and the lifting comb teeth 2 effectively prevents the leakage of manure and reduces the spread of pollution sources, avoids the risk of pig hooves getting stuck, and ensures the safety of breeding.

[0058] By collecting liquids and solids separately, the cleanliness of the breeding sheds was effectively controlled, avoiding the mixing of liquids and solids, reducing the difficulty of cleaning, and providing convenience for subsequent treatment.

[0059] The hot and cold water circulation system can continuously clean the comb teeth, which not only reduces the growth of bacteria, but also improves the ambient temperature in the breeding house and avoids discomfort caused by high temperature.

[0060] The combination of pulley block 13 and guide rail 6 allows the solid material collection box 7 to slide and flip easily, improving the cleaning efficiency of solid materials.

[0061] Through the above technical solution, this embodiment achieves efficient automatic cleaning and manure collection functions, providing a more intelligent solution for modern pig farming.

[0062] Example 2:

[0063] like Figures 1 to 13 As shown in Example 1, this example further optimizes the working principle and operation of the automatic manure cleaning pig farm, especially in terms of comb structure, separation of solid and liquid materials, equipment drive and air circulation regulation. The following is a detailed design and working principle of this example.

[0064] To prevent pigs' hooves from getting stuck between the fixed comb teeth 1 and the lifting comb teeth 2, the distance between the comb teeth was specially designed to be smaller than the outer diameter of the pig's hoof. Specifically, the distance between two adjacent comb teeth on the fixed comb teeth 1 and between two adjacent comb teeth on the lifting comb teeth 2 is designed to be smaller than the outer diameter of the pig's hoof, thus ensuring that the pig's hoof will not get stuck between the comb teeth. This design not only improves the safety of the pigsty, but also prevents the pig's hoof from being pinched by the comb teeth when it moves, causing discomfort.

[0065] The lifting operating rod 5 is fixedly connected to the end of the second barrier 4 away from the fixed comb teeth 1 via a sliding connection. The top of the lifting operating rod 5 is fixedly connected to the second barrier 4 via a pin 12. Through this connection design, the height of the lifting comb teeth 2 can be easily adjusted, and the spacing between the comb teeth can be flexibly controlled to adapt to different cleaning needs. It can remove both liquid and solid substances.

[0066] The bottom of the solid material collection box 7 is slidably connected to the guide rail 6 via the pulley group 13. The guide rail 6 is bent downward at the end near the solid material storage box 10. When the solid material collection box 7 slides to the bent part, the solid material collection box 7 can be flipped downward. This design uses gravity to make the solid material on the solid material collection box 7 fall naturally into the solid material storage box 10, thereby realizing the effective collection and storage of solid materials.

[0067] The pulley block 13 is located at the upper end of the guide rail 6. One of the pulleys is equipped with a drive motor, which drives the pulley to rotate, thereby causing the solid material collection box 7 to slide smoothly on the guide rail 6. With the cooperation of the drive motor, the operator can more easily control the movement of the solid material collection box 7, reduce manual intervention, and improve cleaning efficiency. In addition, a support plate 14 is also provided at the outer end of the breeding box. The support plate 14 is used for the movement of the breeding personnel, ensuring that the breeding personnel can operate safely and conveniently.

[0068] When liquid needs to be removed, the lifting comb teeth 2 are moved down appropriately, increasing the distance between the fixed comb teeth 1 and the lifting comb teeth 2. When the distance between the comb teeth increases, the liquid flows into the liquid collection tank 8 through the gap between the comb teeth under the action of gravity. The liquid collection tank 8 is tilted, and the liquid flows from the collection tank 8 to the liquid storage tank 11, completing the collection and storage of the liquid. In this way, the cleaning and storage process of liquid is automated, reducing manual intervention and improving work efficiency.

[0069] When it is necessary to adjust the airflow in the pigsty, the lifting comb 2 can move downwards, thereby increasing the gap between the fixed comb 1 and the lifting comb 2. This design effectively increases the airflow, helps to improve ventilation efficiency, keeps the air in the pigsty fresh, reduces the odor produced by manure, and improves the growth environment of pigs.

[0070] Working principle

[0071] Automatic sewage cleaning:

[0072] During the pigs' activity, the pig manure is automatically discharged through the gap between the fixed comb teeth 1 and the lifting comb teeth 2. When liquid needs to be cleaned, the lifting comb teeth 2 move down, increasing the gap between the fixed comb teeth 1 and the lifting comb teeth 2. The liquid flows into the top of the liquid collection tank 8 under the action of gravity, and then flows into the liquid storage tank 11 through the liquid collection tank 8.

[0073] Automatic collection and disposal of solid materials:

[0074] To remove solid matter from the pigsty, the lifting comb 2 moves downward, and the solid matter falls through the gaps between the comb teeth. The solid matter collection box 7 moves to the required position to collect the fallen solid matter. When the solid matter collection box 7 slides above the solid matter storage box 10, the pulley group 13 drives the solid matter collection box 7 to flip. Gravity causes the solid matter to fall into the solid matter storage box 10, thereby realizing the automatic separation of solid matter and liquid matter.

[0075] Temperature control and airflow regulation:

[0076] During the breeding process, the temperature and airflow of the breeding house are adjusted as needed. When the temperature needs to be raised, hot water is introduced into the fixed comb teeth 1 through the external hot water circulation system; when the temperature needs to be lowered, cold water is introduced into the lifting comb teeth 2 through the external cold water circulation system. At the same time, by adjusting the height of the lifting comb teeth 2, the gap between the fixed comb teeth 1 and the lifting comb teeth 2 is increased, thereby increasing the airflow and improving the ventilation effect.

[0077] The automatic cleaning design in this embodiment can efficiently clean pig manure, especially the automatic separation and collection of liquid and solid substances, reducing manual intervention and improving cleaning efficiency.

[0078] The design of the comb teeth spacing prevents pig hooves from getting stuck between the comb teeth, improving the safety of the breeding environment and ensuring that pigs can move freely without hindrance.

[0079] The design of the solid matter collection box 7 and the liquid matter collection tank 8 allows solid matter and liquid matter to be stored separately, avoiding mixed contamination and ensuring the cleanliness and hygiene of the breeding environment.

[0080] By regulating the temperature and airflow inside the pigsty, a comfortable breeding environment can be ensured, providing more suitable growth conditions for pigs and promoting their healthy growth.

[0081] With the design of a drive motor and pulley system, operators can easily control the movement and flipping of the solid material collection box 7, improving work efficiency.

[0082] Based on the above design and working principle, this embodiment optimizes the cleaning process and enhances the automation and intelligence level of the equipment, providing a more efficient and safer solution for modern pigsty management.

[0083] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be modified within the scope of the concept described herein through the above teachings or related technologies or knowledge.
