Description

Technical Field

[0001] The invention relates to the technical field of pig breeding, and in particular to a pig breeding house capable of automatically cleaning excrement. Background Art

[0002] At present, the pig farming industry is facing the problems of environmental pollution and difficulty in cleaning. The traditional method of cleaning breeding houses relies on manual cleaning, which is labor-intensive. In addition, due to the humid breeding environment, bacteria are easily bred and odors are produced, posing a hidden danger to the health of pigs. In order to improve the sanitary conditions of the breeding environment, many patents have proposed different automatic cleaning solutions.

[0003] Chinese invention patent application CN117158327A discloses a pig breeding house with automatic manure cleaning, including a house body, a bottom trough, a manure conveyor belt, and cleaning liquid and dry gas for cleaning support rods. The system collects and processes manure through the conveyor belt, and can clean the support rods, reducing the residual manure on the support rods. However, the cleaning method of this design mainly relies on the manure conveyor belt for material transportation, fails to effectively separate solid and liquid substances, and the sealing and cleaning efficiency during the cleaning process still have room for improvement.

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

[0005] Although the above design effectively improves the cleanliness of the breeding environment, it still has some limitations. First, the manure conveyor belt and chain transmission device in the prior art are relatively simple, and fail to achieve effective separation of solid and liquid substances. In addition, the transmission parts are prone to wear during long-term operation, resulting in frequent maintenance and high costs. Secondly, although the manure can be cleaned, the secondary contamination of the manure cannot be effectively avoided during the cleaning process, and good sealing cannot be maintained during the entire cleaning process, which easily leads to odor leakage and bacterial spread in the environment.

[0006] In view of these deficiencies, the present invention proposes a new automatic cleaning solution, which adopts staggered fixed comb teeth and lifting comb teeth, and realizes effective separation and automatic collection of solid and liquid substances through the design of adjustable comb tooth spacing. Through the improved liquid and solid collection system, as well as temperature and ventilation adjustment functions, the present invention can better solve the problems of low efficiency, secondary pollution and high maintenance cost existing in traditional cleaning methods. Summary of the invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a pig breeding house that automatically cleans excrement to solve the above-mentioned problems.

[0008] The objective of the present invention is achieved through the following technical scheme: a pig breeding house for automatically cleaning manure and sewage, comprising a plurality of breeding boxes connected in sequence, the breeding box comprising fixed comb teeth symmetrically arranged on the left and right, a lifting comb tooth is arranged between two fixed comb teeth, the comb teeth on the lifting comb teeth and the comb teeth on the fixed comb teeth are staggered, the comb teeth of the fixed comb teeth and the lifting comb teeth are both hollow structures, the comb teeth hollow part of the fixed comb teeth is connected to an external hot water circulation system through a pipeline, the comb teeth hollow part of the lifting comb teeth is connected to an external cold water circulation system through a pipeline, the top of the fixed comb teeth is clamped with a fence one and a fence two, the two ends of the lifting comb teeth pass through the fence two, and the penetrating parts are fixedly connected with a lifting operating rod, the bottom end of the breeding box is fixedly connected with a guide rail symmetrically arranged front and back, a solid collection box is slidably connected between the two guide rails, the bottom ends of the two guide rails are fixedly connected with a liquid collection tank, the bottom end of the liquid collection tank is fixedly connected with a base, and the two ends of the base along the length direction of the solid collection box are respectively fixedly connected with a solid storage box and a liquid storage box.

[0009] The comb teeth on the fixed comb teeth and the lifting comb teeth are arranged to contact each other, so that the bottom end of the breeding box is sealed and the pigs can move freely on the top ends of the fixed comb teeth and the lifting comb teeth.

[0010] The distance between two adjacent comb teeth on the fixed comb teeth and the distance between two adjacent comb teeth on the lifting comb teeth are both smaller than the outer diameter of the trotters of the live pigs raised thereon, so that the trotters of the live pigs will not be stuck between the two comb teeth.

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

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

[0013] The guide rail is bent downward near one end of the solid object storage box, so that the solid object collection box can be turned downward when sliding to the bent portion, thereby causing the solid objects on the solid object collection box to be dumped into the solid object storage box.

[0014] The liquid collection tank has a V-shaped structure along the cross section between the solid storage tank and the liquid storage tank. The liquid collection tank is inclined, and one end of the liquid collection tank close to the liquid storage tank is lower than the end close to the solid storage tank.

[0015] A driving motor is arranged on one of the pulleys at the upper end of the guide rail, and is used to drive the pulley to rotate. A supporting plate is arranged at the outer end of the breeding box, and the supporting plate is used for the activities of breeding personnel.

[0016] When the lifting comb teeth move downward, the comb teeth on the lifting comb teeth and the comb teeth on the fixed comb teeth move away from each other, so that the feces and dirt on the top of the fixed comb teeth and the lifting comb teeth fall to the bottom of the fixed comb teeth and the lifting comb teeth under the action of gravity. When the distance between the comb teeth is small, liquid matter flows out from the gaps, and when the distance between the comb teeth is large, solid matter falls from between the comb teeth.

[0017] The beneficial effects of the present invention are: 1. The present invention realizes the function of automatically cleaning pig manure through the staggered arrangement of fixed comb teeth and lifting comb teeth and the adjustable comb teeth spacing. Liquid and solid substances are automatically separated under the action of gravity and collected into the liquid collection tank and the solid collection box respectively, which greatly reduces the need for manual intervention, reduces labor intensity, and improves cleaning efficiency.

[0018] 2. The design of the comb teeth spacing fully considers the outer diameter of the pig's trotter, so that the distance between the comb teeth is smaller than the outer diameter of the trotter, thereby effectively avoiding the problem of the pig's trotter being stuck during activities. This design ensures the free movement of the pigs, reduces the injury or discomfort caused by the comb teeth getting stuck, and improves the safety of the breeding environment.

[0019] 3. The present invention adopts a design in which the liquid collection tank and the solid collection box are independent of each other, so that the liquid and solid can 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 manure management.

[0020] 4. The present invention can adjust the temperature in the breeding house through the cooperation of the hot water circulation system and the cold water circulation system to ensure that the temperature is always within an appropriate range. In addition, the design of the lifting comb teeth allows the air flow to be adjusted as needed, thereby 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.

[0021] 5. The design of combining a pulley block with a guide rail allows the solid matter collection box to slide smoothly on the guide rail, and when it reaches above the solid matter storage box, it can be flipped over to dump the solid matter into the storage box. This design effectively utilizes the principle of gravity, simplifies the process of solid matter collection and processing, and improves the convenience of operation and cleaning efficiency.

[0022] 6. Due to the automatic cleaning function of the present invention, the farm does not need to rely on a large number of manual workers for cleaning work. The equipment can automatically complete the separation, cleaning and storage of solid and liquid substances, which greatly saves labor costs and reduces possible omissions and pollution during manual cleaning, thereby improving the scientificity and modernization of breeding management.

[0023] 7. The present invention is designed with easy-to-operate pulley blocks, motor drives, adjustment rods and other structures, so that farmers can easily adjust and maintain the equipment. The design of the lifting operating rod and the enclosure makes the equipment adjustment more flexible. Users can easily control the movement and height adjustment of the comb teeth as needed, which improves the operability of the equipment and the convenience of maintenance.

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0028] Embodiment 1: like Figures 1 to 13 As shown, the present embodiment provides a pig breeding house with automatic manure cleaning, which adopts a plurality of breeding boxes 1 connected in sequence, each breeding box is composed of fixed comb teeth 1 and lifting comb teeth 2, and the fixed comb teeth 1 and the lifting comb teeth 2 are respectively combined by staggered configuration and hollow structure to ensure that the pig manure can be effectively cleaned during the breeding process.

[0029] The comb teeth on the fixed comb teeth 1 and the lifting comb teeth 2 are arranged alternately, and the hollow parts of the comb teeth are connected to the external hot water and cold water circulation systems through pipes. Specifically, the fixed comb teeth 1 are connected to the hot water circulation system through pipes, and the lifting comb teeth 2 are connected to the cold water circulation system through pipes. The hot water system helps with cleaning and disinfection, and the cold water system is used for cooling and reducing the temperature burden in the breeding house.

[0030] The comb teeth on the fixed comb teeth 1 and the lifting comb teeth 2 contact each other and seal the bottom end of the breeding box to form a closed working area, ensuring that the pigs can move within the area without getting stuck, while preventing manure leakage and enhancing the cleaning effect.

[0031] The top of each breeding box is closed by enclosure 1 3 and enclosure 2 4, which together ensure the safe movement of pigs in the breeding box. The penetrating parts at both ends of the lifting comb teeth 2 are connected to the lifting operating rod 5, which is convenient for the operator to adjust the height of the lifting comb teeth 2 as needed to achieve automatic cleaning of feces and sewage.

[0032] A guide rail 6 is installed at the bottom of the breeding box, and a solid collection box 7 is slidably connected to the guide rail 6. The solid collection box 7 is slidably connected to the guide rail 6 through a pulley block 13. The pulley block 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 collection box 7 can move along the guide rail 6, which is convenient for collecting and processing solid feces.

[0033] The solid collecting trough 8 is located at the bottom end of the guide rail 6 and is connected to the liquid collecting trough 8. The liquid collecting trough 8 adopts a V-shaped structure and is tilted. The end close to the liquid storage tank 11 is lower to ensure that the liquid can flow into the liquid storage tank 11.

[0034] The liquid collecting tank 8 can effectively guide the liquid to flow to the liquid storage tank 11 through its inclined design and V-shaped structure. This design ensures that the liquid does not accumulate, thereby avoiding the generation of odor or the breeding of bacteria.

[0035] The working principle of this embodiment is as follows: When the live pigs move in the breeding box 1, the fixed comb teeth 1 and the lifting comb teeth 2 are interlaced to seal the bottom of the breeding box. The live pigs collect excrement under the comb teeth through contact with the comb teeth.

[0036] By operating the lifting comb teeth 2 through the lifting operating rod 5, the distance between the comb teeth can be adjusted, so that solid matter and liquid matter can fall or flow to the liquid matter collection tank 8 and the solid matter collection box 7 according to the change of the comb teeth spacing.

[0037] The solid object collecting box 7 slides on the guide rail 6 via the pulley block 13 , and when it approaches the solid object storage box 10 , the solid objects fall into the solid object storage box 10 via the flipping mechanism.

[0038] The liquid collecting tank 8 guides the liquid to flow to the liquid storage tank 11 through an inclined design. Through this process, the liquid avoids water accumulation or pollution, thereby maintaining the cleanliness of the breeding environment.

[0039] Through the hot water and cold water circulation system, the comb teeth parts on the fixed comb teeth 1 and the lifting comb teeth 2 are continuously kept clean, reducing the generation of bacteria and odor.

[0040] The structural design in this embodiment can realize automatic cleaning of manure and sewage in the breeding box, improve the sanitary conditions of the pig breeding environment, and reduce the workload of manual cleaning.

[0041] The staggered arrangement and sealing effect of the fixed comb teeth 1 and the lifting comb teeth 2 effectively prevent leakage of manure and sewage, reduce the spread of pollution sources, avoid the risk of pig trotters being stuck, and ensure the safety of breeding.

[0042] By collecting liquids and solids separately, the cleanliness level in the breeding house is effectively controlled, avoiding the mixing of liquids and solids, reducing the difficulty of cleaning, and providing convenience for subsequent processing.

[0043] 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.

[0044] The combination of the pulley block 13 and the guide rail 6 enables the solid matter collecting box 7 to slide and flip conveniently, thereby improving the cleaning efficiency of the solid matter.

[0045] Through the above technical solution, this embodiment realizes efficient automatic cleaning and manure collection functions, providing a more intelligent solution for modern pig farming.

[0046] Embodiment 2: like Figures 1 to 13 As shown, based on Example 1, this embodiment further optimizes the working principle and operation of the pig breeding house with automatic cleaning of manure, especially in the improvements of comb tooth structure, separation of solid and liquid matter, equipment drive and air circulation regulation. The following is the detailed design and working principle of this embodiment.

[0047] In order to prevent the pig's trotters from getting stuck between the fixed comb teeth 1 and the lifting comb teeth 2, the distance between the comb teeth is specially designed to be smaller than the outer diameter of the pig's trotters. Specifically, the distance between two adjacent comb teeth on the fixed comb teeth 1 and the distance between two adjacent comb teeth on the lifting comb teeth 2 are designed to be smaller than the outer diameter of the pig's trotters of farmed pigs, thereby ensuring that the pig's trotters will not get stuck between the comb teeth. This design not only improves the safety of the pig house, but also avoids the pig's trotters being caught by the comb teeth when moving, causing discomfort.

[0048] The lifting operating rod 5 is fixedly connected to the end of the enclosure 2 4 away from the fixed comb teeth 1 through a sliding connection, and the top of the lifting operating rod 5 is fixedly connected to the enclosure 2 4 through a pin 12. Through this connection design, the height of the lifting comb teeth 2 can be easily adjusted to achieve flexible control of the spacing between the comb teeth, thereby adapting to different cleaning needs, and being able to remove both liquid and solid objects.

[0049] The bottom end of the solid object collection box 7 is slidably connected to the guide rail 6 through a pulley set 13. The guide rail 6 is bent downward near one end of the solid object storage box 10. When the solid object collection box 7 slides to the bent part, the solid object collection box 7 can be flipped downward. This design uses gravity to make the solid matter on the solid object collection box 7 naturally fall into the solid object storage box 10, thereby realizing effective collection and storage of solid matter.

[0050] The pulley block 13 is located at the upper end of the guide rail 6, and a driving motor is provided on one of the pulleys. The driving motor is used to drive the pulley to rotate, thereby driving the solid matter collection box 7 to slide smoothly on the guide rail 6. Through the cooperation of the driving motor, the operator can more easily control the movement of the solid matter 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 activities of the breeding personnel to ensure that the breeding personnel can operate safely and conveniently.

[0051] When it is necessary to remove liquid, the lifting comb teeth 2 are appropriately moved downward to increase the distance between the fixed comb teeth 1 and the lifting comb teeth 2. When the distance between the comb teeth increases, the liquid material flows into the liquid collection tank 8 through the comb tooth gap 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 box 11, completing the collection and storage of the liquid material. In this way, the cleaning and storage process of the liquid is automated, reducing manual intervention and improving work efficiency.

[0052] When it is necessary to adjust the air flow in the breeding house, the lifting comb teeth 2 can move downward, thereby increasing the gap between the fixed comb teeth 1 and the lifting comb teeth 2. This design effectively increases the air flow, helps to improve ventilation efficiency, keep the air in the pig house fresh, reduce the odor generated by manure, and improve the growth environment of pigs.

[0053] How it works Automatic manure cleaning: When the pigs are moving, the excrement produced by the pigs is automatically discharged through the comb tooth 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 downward to increase the distance between the fixed comb teeth 1 and the lifting comb teeth 2. The liquid substance flows into the top of the liquid collection tank 8 under the action of gravity, and flows into the liquid storage tank 11 through the liquid collection tank 8.

[0054] Automatic collection and dumping of solid matter: In order to remove solid matter in the pig house, the lifting comb teeth 2 move downward, and the solid matter falls through the gap between the comb teeth. The solid matter collecting box 7 moves to the required position to collect the fallen solid matter. When the solid matter collecting box 7 slides above the solid matter storage box 10, the pulley group 13 drives the solid matter collecting box 7 to flip over, and the 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.

[0055] Temperature control and air flow regulation: During the breeding process, the temperature and air flow of the breeding house are adjusted as needed. When the temperature needs to be increased, 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, the air flow is increased, and the ventilation effect is improved.

[0056] The automatic cleaning design in this embodiment can efficiently clean pig manure, especially the automatic separation and collection of liquid and solid substances, which reduces manual intervention and improves cleaning efficiency.

[0057] The design of the comb teeth spacing prevents pig hooves from getting stuck between the comb teeth, improves the safety of the breeding environment, and ensures that pigs can move freely without hindrance.

[0058] The design of the solid matter collecting box 7 and the liquid matter collecting tank 8 enables the solid matter and the liquid matter to be effectively stored separately, avoiding mixed contamination and ensuring the cleanliness and hygiene of the breeding environment.

[0059] By adjusting the temperature and air flow in the breeding house, the comfort of the breeding environment is ensured, providing more suitable growth conditions for pigs and promoting their healthy growth.

[0060] By adopting the design of the driving motor and the pulley block, the operator can easily control the movement and flipping of the solid matter collection box 7, thereby improving the work efficiency.

[0061] Through the above-mentioned design and working principle, this embodiment optimizes the cleaning process on the basis of Embodiment 1, enhances the automation and intelligence level of the equipment, and provides a more efficient and safe solution for modern pig house management.

[0062] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be regarded 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 the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, and should all be within the scope of protection of the claims attached to the present invention.
