Description

Technical Field

[0001] This invention relates to the field of livestock farming technology, and more specifically, to a livestock urine buffering and fixed-point discharge device and method. Background Technology

[0002] Environmental pollution caused by livestock and poultry manure from large-scale farms is a major source of pollution in the livestock industry, and the large amounts of urine produced in these farms are also a source of foul odors. These liquids contain high levels of nitrogen and acidic substances, and may also lead to other environmental problems. Therefore, proper collection of urine is crucial for solving pollution problems in livestock farms and for facilitating the efficient utilization of urine.

[0003] Livestock primarily excrete feces and urine during defecation, and they do so at irregular intervals and in various locations. Currently, there is no known method for separating feces and urine at the source; most methods involve mixing the feces and urine and then separating the solid and wet parts together. This invention aims to solve the problem of fecal separation at the source, which is more conducive to the separation of solid and wet feces and reduces air pollution in livestock sheds. Summary of the Invention

[0004] The purpose of this invention is to provide a livestock urine buffer and fixed-point discharge device, which can collect urine from the source of the female animal and intelligently release, discharge urine at fixed points and collect it uniformly, which is conducive to the dry and wet separation of feces and further helps to reduce air pollution in the breeding house.

[0005] Another objective of this invention is to provide a method for intelligent slow-release collection of urine from female animals, which can collect urine from the source of the female animals and intelligently release, discharge urine at designated points and collect it uniformly, which is beneficial for the dry and wet separation of feces and further helps to reduce air pollution in the breeding shed.

[0006] The technical solution of this invention is implemented as follows:

[0007] A livestock urine buffering and fixed-point discharge device includes: a urine collection hood, a lower collection bladder, an upper collection bladder, a tail power pump, and a fixed-point urine discharge system;

[0008] One end of the urine collection hood is a urine inlet, which is attached to the urination port of the female animal. The other end of the urine collection hood is a urine outlet, which is connected to the lower collection sac. The lower collection sac is tied to the waist and abdomen of the female animal, and the upper collection sac is tied to the top and back of the female animal.

[0009] The upper liquid collection bladder and the lower liquid collection bladder are connected by a liquid guide tube, and the liquid guide tube is equipped with an upper liquid check valve. The upper liquid collection bladder is also equipped with a drain pipe.

[0010] The tail pump is connected to the upper liquid collection bladder and is used to draw gas from the upper liquid collection bladder.

[0011] The positioning urination system includes a locator, an electronic urination valve, and a positioning base station. The locator is located on the upper collection bladder, and the electronic urination valve is located on the drainage pipe. The locator has a built-in controller and is electrically or communicatively connected to the electronic urination valve. The positioning base station also has a controller and is able to provide feedback on the location of the locator within its monitoring range. The locator is electrically or communicatively connected to the controller of the positioning base station.

[0012] Furthermore, the tail power pump is located at the base of the female animal's tail. The tail power pump includes a folded air bladder and a tail pad. The tail pad is located at the bottom of the folded air bladder. The longitudinal section of the folded air bladder is semi-circular. The folded air bladder and the tail pad form a channel for the female animal's tail to pass through. The folded air bladder is connected to the upper liquid collection bladder through an air extraction pipe. The folded air bladder is connected to the outside air through an exhaust pipe. An air extraction check valve is provided on the air extraction pipe, and an exhaust check valve is provided on the exhaust pipe.

[0013] Furthermore, the tail power pump is located at the base of the female animal's tail. The tail power pump includes a tail pad and a folding airbag assembly. The folding airbag assembly includes at least two folding airbags. All the folding airbags are arranged sequentially and form a semi-circular shape. The tail pad is located at the bottom of the folding airbag assembly. The folding airbags and the tail pad form a channel for the female animal's tail to pass through.

[0014] Each of the folded airbags is connected to the upper liquid collection bag via an air extraction pipe, and each of the folded airbags is connected to the outside air via an exhaust pipe. Each air extraction pipe is equipped with an air extraction check valve, and each exhaust pipe is equipped with an exhaust check valve.

[0015] Furthermore, the folding airbag assembly includes three folding airbags.

[0016] Furthermore, it also includes a fixing unit for binding the urine collection cover, the lower collection sac and the upper collection sac, the fixing unit including a waist belt, an upper back strap and a lower back strap, the waist belt being connected to both the upper collection sac and the lower collection sac, for binding the upper collection sac and the lower collection sac to the top back and waist and abdomen of the female animal respectively.

[0017] One end of the upper shoulder strap is connected to the upper middle part of the waist belt, and the other end is connected to the upper end of the urine collection cover; one end of the lower shoulder strap is connected to the lower end of the urine collection cover, and the other end is connected to the lower collection sac or the lower middle part of the waist belt.

[0018] Furthermore, the belt is composed of several belt segments connected end to end, and adjacent belt segments are connected by Velcro or by elastic straps and hook assemblies.

[0019] Furthermore, the upper shoulder straps are provided as two symmetrically arranged, and the upper shoulder straps are fastened to the urine collection cover by a snap fastener;

[0020] The lower shoulder straps are provided as two symmetrically arranged, and the lower shoulder straps are fastened to the lower end of the urine collection cover by a snap fastener.

[0021] Furthermore, the lower fluid collection sac includes a left-side fluid collection sac and a right-side fluid collection sac that are connected or communicate with each other, and the left-side fluid collection sac and the right-side fluid collection sac are respectively tied to the left and right sides of the female animal's waist and abdomen.

[0022] Furthermore, the liquid guiding tube is configured as two tubes, and the upper liquid collecting bladder is connected to the left side liquid collecting bladder and the right side liquid collecting bladder respectively through the two liquid guiding tubes.

[0023] The method based on the aforementioned livestock urine buffering and fixed-point discharge device includes the following steps:

[0024] S1: Attach the urine inlet of the urine collection hood to the urination port of the female animal, then tie the lower collection bladder to the waist and abdomen of the female animal, tie the upper collection bladder to the top back of the female animal, and install the tail power pump at the base of the female animal's tail.

[0025] S2: When the female animal urinates, the urine flows through the urine collection hood to the inner cavity of the lower collection sac. The tail power pump draws in the gas in the upper collection sac, creating negative pressure in the upper collection sac and opening the upper liquid check valve. Under the negative pressure, the urine in the lower collection sac flows upward through the liquid guide tube to the upper collection sac, preventing the lower collection sac from bursting due to excessive liquid accumulation, or preventing the lower collection sac from being squeezed and ruptured by the female animal in the process of crowding with other female animals.

[0026] S3: A urine collection chamber can be set at the feeding location of the female animal or other designated locations. Since the locator is installed on the female animal, the high-precision coordinates of the female animal are provided by the positioning base station. When the female animal moves to the urine collection chamber, the urine discharge electronic valve is opened, and the urine in the upper collection sac is discharged into the urine collection chamber through the discharge pipe, thus completing intelligent positioning and urine collection.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This application provides a livestock urine buffering and targeted discharge device, which is installed at the hindquarters of livestock (especially female livestock). The urine collection hood's inlet is attached to the female livestock's urination port. The lower collection bladder is then strapped to the female livestock's waist and abdomen, and the upper collection bladder is strapped to the top and back of the female livestock. A tail pump is installed at the base of the female livestock's tail. When the female livestock urinates, urine flows from the urine collection hood to the lower collection bladder. The tail pump then draws in negative pressure, drawing the urine from the lower collection bladder to the upper collection bladder. The installation of a locator provides high-precision coordinates of the female livestock via a positioning base station. When the female livestock moves to the urine collection chamber or a designated urination location, the electronic urination valve is opened, and the urine in the upper collection sac is discharged into the urine collection chamber or designated urination location through the discharge pipe. This completes intelligent fixed-point urination and unified collection and treatment, so as to facilitate the intelligent slow-release collection of urine from all female livestock sources in the farm. This fixed-point urination and unified collection is beneficial for the dry and wet separation of feces and urine, and is more conducive to reducing air pollution in the farmhouse.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0049] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0050] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] Example 1

[0055] like Figures 1-10 This embodiment provides a livestock urine buffering and fixed-point discharge device, which includes: a urine collection hood 1, a lower collection bladder 2, an upper collection bladder 3, a tail power pump 4, and a fixed-point urine discharge system. This device can be applied to many female livestock, such as sows, cows, ewes, and donkeys; especially to cows, such as female dairy cows. This application is mainly designed for dairy farms, and the following detailed description uses cows as an example.

[0056] One end of the urine collection cover 1 is a urine inlet 101, which can be pear-shaped, oval, or round, etc. The shape of the urine inlet 101 corresponds to the cow's urination opening, and the size of the urine inlet 101 needs to be slightly larger than the cow's urination opening. When the urine collection cover 1 is actually installed, it is installed at the cow's tail urination opening. The urine collection cover 1 plays a role in guiding urine discharge. The urine inlet 101 of the urine collection cover 1 is tightly attached to the cow's urination opening so as to minimize leakage when the cow urinates and to concentrate as much urine as possible into the urine inlet 101. The other end of the urine collection cover 1 is a urine outlet, which is connected to the lower collection sac 2. The lower collection sac 2 is tied to the cow's waist and abdomen, and the upper collection sac 3 is tied to the cow's top back. The urine discharged into the urine inlet 101 flows naturally to the lower collection sac 2 for temporary storage under the action of gravity.

[0057] The upper collecting sac 3 and the lower collecting sac 2 are connected by a liquid guide tube 6, and the liquid guide tube 6 is equipped with an upward liquid check valve. The upper collecting sac 3 is also equipped with a drain pipe 7. The tail power pump 4 is connected to the upper collecting sac 3 and is used to draw gas from the upper collecting sac 3. Under the suction action of the tail power pump 4, the urine temporarily stored in the lower collecting sac 2 flows upward through the liquid guide tube 6 back to the upper collecting sac 3 for storage. Because the liquid guide tube 6 is equipped with an upward liquid check valve, it ensures that the urine in the lower collecting sac 2 can only flow upward to the upper collecting sac 3, and the urine in the upper collecting sac 3 cannot flow back to the lower collecting sac 2.

[0058] The design of the localized urination system is as follows:

[0059] The positioning and urination system includes a locator 5, an electronic urination valve, and a positioning base station. The positioning base station is typically installed indoors. The locator 5 is installed on the upper collection bladder 3, and the electronic urination valve is installed on the drainage pipe 7. The locator 5 is used in conjunction with the electronic urination valve. The locator 5 has a built-in controller and is electrically or communicatively connected to the electronic urination valve. The positioning base station also has a controller, which can provide feedback on the location of the locator 5 within its monitoring range. The locator 5 is electrically or communicatively connected to the controller of the positioning base station. Preferably, the locator 5 and the positioning base station are connected wirelessly, eliminating the need for a wired connection. This avoids the safety issues that could arise from multiple cows in the farm being tethered or pulled by the wires during movement. The communication connection using Wi-Fi or Bluetooth effectively avoids this safety problem and also prevents the movement of individual cows in the farm from being restricted. After the locator 5 is connected to the positioning base station, the positioning base station can monitor the location of the locator 5 and return the location to the locator 5. The controller of the locator 5 can determine the location of the cow and provide the cow with high-precision coordinates through the positioning base station. When the cow moves to the urine collection bin or the designated urination location, the controller of the locator 5 controls the opening of the urination electronic valve, and the urine in the upper collection bladder 3 is discharged into the urine collection bin or the designated urination location through the discharge pipe 7, completing the intelligent fixed-point urination and unified collection and treatment. The process of temporarily storing the urine in the upper collection bladder 3 and then discharging it to the urine collection bin or the designated urination location is actually a slow release process of cow urine (the cow's urine is temporarily stored after urination and then uniformly discharged and collected).

[0060] It should be noted that the tail pump 4 can be a miniature electric pump for suction. This miniature electric pump is installed on the cow, with its suction end connected to the upper collection bladder 3 and its exhaust end connected to the outside air. A battery can also be installed, electrically connected to the miniature electric pump to provide power. This miniature electric pump can also communicate with the controller of the positioning base station, allowing the controller to control its operation. Alternatively, the tail pump 4 can also be an air bladder, where the cow's tail swinging motion creates negative pressure by compressing the air bladder, thereby suctioning gas from the upper collection bladder 3.

[0061] In this embodiment, the tail power pump 4 adopts the form of an airbag, specifically in the following two ways:

[0062] The first type: The tail power pump 4 is installed at the base of the female animal's tail. The tail power pump 4 includes a folding airbag 401 and a tail pad 402. The folding airbag 401 is a foldable airbag that can elastically recover after being compressed. The tail pad 402 is located at the bottom of the folding airbag 401. The longitudinal section of the folding airbag 401 is semi-circular or approximately semi-circular in shape. The folding airbag 401 and the tail pad 402 form a channel 403 for the female animal's tail to pass through. Figure 9 As shown, the longitudinal section of the tail pad 402 is arc-shaped, forming the channel 403 with the inner ring space of the folded air bladder 401. The folded air bladder 401 is connected to the upper fluid collection bladder 3 through an air extraction pipe 404, and the folded air bladder 401 is connected to the outside air through an exhaust pipe 405. An air extraction check valve is provided on the air extraction pipe 404, and an exhaust check valve is provided on the exhaust pipe 405. One or more air extraction pipes 404 and one or more exhaust pipes 405 can be provided; preferably, only one air extraction pipe 404 and only one exhaust pipe 405 are provided. Regardless of the direction the cow swings its tail, it will cause the folded air bladder 401 to be compressed and open the air extraction check valve on the air extraction pipe 404, drawing air from the upper fluid collection bladder 3.

[0063] The second type: The tail power pump 4 is located at the base of the female animal's tail. The tail power pump 4 includes a tail pad 402 and a folded airbag 401 assembly. The folded airbag 401 is a foldable airbag with a folded membrane structure, capable of elastic recovery after being compressed. The folded airbag 401 assembly includes at least two folded airbags 401; preferably, in this embodiment, the folded airbag 401 assembly includes three folded airbags 401, arranged sequentially and forming a semi-circular or approximately semi-circular shape. It should be noted that this structure is similar to the first type, the main difference being that the first type is a large, integrally formed semi-circular airbag, while the second type is composed of three smaller airbags joined together to form a semi-circle. The tail pad 402 is located at the bottom of the folded airbag 401 assembly, and the folded airbag 401 and the tail pad 402 form a channel 403 for the female animal's tail to pass through. Figure 6 and Figure 10 As shown. Each folded airbag 401 is provided with an air extraction pipe 404 and is connected to the upper liquid collection bag 3 through the air extraction pipe 404. Each folded airbag 401 is provided with an exhaust pipe 405 and is connected to the outside air through the exhaust pipe 405. Each air extraction pipe 404 is provided with an air extraction check valve, and each exhaust pipe 405 is provided with an exhaust check valve.

[0064] In this embodiment, the airbag-type tail power pump 4 preferably adopts the second structure described above. In actual use, the cow's tail passes through the channel 403 and is supported by the tail pad 402. The three folding airbags 401 mainly supplement the power process of the cow's tail tilting up and down to the right, tilting up and down vertically, and tilting up and down to the left. When the folding airbags 401 bend upwards and downwards, the folding and opening of the folding airbags 401 are large, resulting in compression and expansion of space. Due to the action of the suction one-way valve, when the folding airbags 401 are compressed, the suction one-way valve closes and the exhaust one-way valve removes excess gas; when the folding airbags 401 are expanded, the exhaust one-way valve closes and the suction one-way valve draws gas from the upper collection bladder 3. The folding airbags 401 repeat this process, and the gas in the upper collection bladder 3 is continuously drawn out, thereby drawing urine from the lower collection bladder to the upper collection bladder 3.

[0065] In this embodiment, a fixing unit is also included for binding the urine collection cover 1, the lower collection sac 2, and the upper collection sac 3. The fixing unit includes a waist belt 10, an upper back strap 8, and a lower back strap 9. The waist belt 10 is connected to both the upper collection sac 3 and the lower collection sac 2, and is used to bind the upper collection sac 3 and the lower collection sac 2 to the top back and waist and abdomen of the female animal, respectively. One end of the upper back strap 8 is connected to the upper middle part of the waist belt 10, and the other end is connected to the upper end of the urine collection cover 1. One end of the lower back strap 9 is connected to the lower end of the urine collection cover 1, and the other end is connected to the lower collection sac 2 or the lower middle part of the waist belt 10.

[0066] Preferably, the belt 10 is composed of several belt segments connected end to end. Adjacent belt segments are joined by Velcro or by an elastic band and hook assembly. The elastic band, i.e., the two ends of an elastic band, forms a hole for hooking. The hook can be a metal hook that is hung in the hole of the elastic band. Because the elastic band is elastic, it can adapt to cows of various sizes. Since the belt 10 is composed of several belt segments connected end to end, it can be flexibly disassembled and installed on the cow. It can also be flexibly removed when necessary.

[0067] Preferably, the upper shoulder straps 8 are provided as two symmetrically arranged, and the upper shoulder straps 8 are fastened to the urine collection cover 1 by a snap fastener; the lower shoulder straps 9 are provided as two symmetrically arranged, and the lower shoulder straps 9 are fastened to the lower end of the urine collection cover 1 by a snap fastener, such as... Figure 4 and Figure 5 As shown. The connection between the upper shoulder strap 8, the lower shoulder strap 9 and the urine collection cover 1 is a detachable connection, which also facilitates the assembly and disassembly of the entire device.

[0068] The lower collection sac 2 includes a left-side collection sac 201 and a right-side collection sac 202 that are connected or communicate with each other, such as Figure 4 As shown, Figure 4 This is a rear view of the device, with the rear view serving as the front view. The left-side fluid collection sac 201 and the right-side fluid collection sac 202 are respectively tied to the left and right sides of the female animal's waist and abdomen to ensure more even force distribution on both sides. The left-side and right-side fluid collection sacs 201 and 202 can be integrally formed, meaning their internal cavities are interconnected; alternatively, the left-side and right-side fluid collection sacs 201 and 202 can be connected but not interconnected, each being an individual unit, with the connection point located in the lower abdomen of the cow via sutures or adhesive.

[0069] The overall working principle of the device is as follows:

[0070] The device is flexibly installed at the cow's rump using a fixing unit. The urine inlet 101 of the urine collection hood 1 is attached to the cow's urination opening. Then, the lower collection sac 2 is tied to the cow's waist and abdomen, and the upper collection sac 3 is tied to the cow's top back. The tail power pump 4 is installed at the base of the cow's tail. When the cow urinates, the urine flows through the urine collection hood 1 into the inner cavity of the lower collection sac 2. The tail power pump 4 uses the power of the cow's tail swinging to draw urine from the lower collection sac 2. Specifically, it draws air from the upper collection sac 3, creating negative pressure and opening the upper liquid check valve. Under the negative pressure, the urine in the lower collection sac 2 flows upward through the liquid guide tube 6 into the upper collection sac 3. This prevents the lower collection sac 2 from expanding or bursting due to excessive liquid accumulation, or prevents the lower collection sac 2 from bursting during crowding with other cows. To ensure the targeted discharge of cow urine, a urine collection chamber can be set up at the feeding location or other designated locations. Since a locator 5 is installed on the cow, the high-precision coordinates of the cow are provided by a positioning base station. When the cow moves to the urine collection chamber, the electronic valve for urination is opened, and the urine in the upper collection sac 3 is discharged into the urine collection chamber through the drainage pipe 7, thus completing intelligent positioning and urine collection.

[0071] Example 2

[0072] This embodiment provides yet another livestock urine buffering and fixed-point discharge device, which differs from Embodiment 1 in that: this embodiment provides a second type of fixed-point urination system, as detailed below:

[0073] The targeted urination system includes: at the cow's end, a short-range communication control device, an electronic urination valve, and an ammonia sensor installed at the end of the drainage pipe 7; a urine collection area is set up at the urine collection location, which mainly includes a fenced electronic scale with a built-in communication device. This communication device is a short-range communication device with a communication distance of approximately 2 meters, just enough to cover the nearest cow. Its basic working principle is that there is a fenced electronic scale (four-point weighing) at the urine collection point, allowing urine to flow in. When the pressure exceeds a threshold (set according to the cow's weight), the fenced electronic scale sends a signal to the communication control device on the cow, indicating that it has entered the urination area. Simultaneously, the ammonia sensor detects that the ammonia concentration exceeds a threshold (high ammonia concentration in the urine collection area; dual-condition judgment improves reliability). Upon receiving this signal, the communication control device controls the electronic urination valve to open and allow urination.

[0074] Example 3

[0075] This embodiment provides a method for the livestock urine buffering and fixed-point discharge device described in Embodiment 1, including the following steps:

[0076] S1: Attach the urine inlet 101 of the urine collection hood 1 to the urination port of the female animal, then tie the lower collection bladder 2 to the waist and abdomen of the female animal, tie the upper collection bladder 3 to the top back of the female animal, and install the tail power pump 4 at the base of the female animal's tail.

[0077] S2: When the female animal urinates, the urine flows through the urine collection hood 1 into the inner cavity of the lower collection sac 2. The tail power pump 4 draws in the gas in the upper collection sac 3, creating a negative pressure in the upper collection sac 3 and opening the upper liquid check valve. Under the negative pressure, the urine in the lower collection sac 2 flows upward through the liquid guide tube 6 into the upper collection sac 3, preventing the lower collection sac 2 from bursting due to excessive liquid accumulation, or preventing the lower collection sac 2 from being squeezed and ruptured during the crowding process between the female animal and other female animals.

[0078] S3: A urine collection chamber can be set at the feeding location of the female animal or other designated locations. Since the locator 5 is installed on the female animal, the high-precision coordinates of the female animal are provided by the positioning base station. When the female animal moves to the urine collection chamber, the urine discharge electronic valve is opened, and the urine in the upper collection sac 3 is discharged into the urine collection chamber through the discharge pipe 7, thus completing intelligent positioning and urine collection.

[0079] The process of using the tail pump 4 to draw urine from the collection sac 2 in step S2 has been described in detail in Example 1 and will not be repeated here.

[0080] It should also be noted that the livestock urine buffer and fixed-point discharge device of this application can also be applied to male livestock. It is only necessary to adjust the position of the urine collection hood accordingly so that the urine inlet of the urine collection hood corresponds to the urine outlet of the male livestock.

[0081] The beneficial effects of the technical solution of the present invention are:

[0082] Since livestock urination is random, it is not conducive to urine collection. Therefore, the device of this application is designed to collect the randomly discharged urine of livestock and then discharge it at a designated location. This application collects urine at the cow's urination opening (the source). The tail-powered pump 4 uses the tail-swinging motion as power to draw the urine temporarily stored in the lower collection sac 2 into the upper collection sac 3. When the cow moves to the designated location, a positioning-controlled urination electronic valve releases the urine buffered in the upper collection sac 3 at the designated location, facilitating unified and precise urine collection. The entire urine release and collection process requires no manual intervention; the livestock automatically discharges urine into the designated location. This achieves dry and wet separation of feces and urine at the source, which is beneficial for the separation of dry and wet feces and reduces air pollution in the livestock shed.
