When the pressure sensor detects that a certain pressure value has been reached, it indicates that most of the liquid in the feces has been squeezed out. At this time, the controller controls the output end of the telescopic rod to open the cover, allowing the dry feces to be transported out. By monitoring the pressure inside the installation cylinder through the pressure sensor, the separation of feces and liquid can be understood. When the personnel observe that the transported feces are relatively wet, the telescopic rod drives the cover to close, continuing to squeeze the feces. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Existing fecal collection devices collect feces and liquids from them in a unified manner. The liquids remain in the feces for a long time, which can easily breed bacteria, affect the environment, and are relatively troublesome to handle later.

[0023] In view of this, the present invention provides a manure separation and collection device for livestock breeding. Through the cooperation between the installation cylinder, the first filter screen and the fixed rod, when the manure is transported through the installation cylinder, the manure moves continuously from inside the installation cylinder to the outside of the breeding area. During the movement, the manure is squeezed, and the liquid in the manure can be squeezed out. The liquid in the manure can flow into the liquid storage cylinder through the first filter screen and the connecting device, thus achieving the effect of separating dry manure and liquid. This avoids the growth of a large number of bacteria in the manure over a long period of time, which would affect the environment. When the liquid level sensor detects that the liquid storage cylinder is full, the liquid can be flowed into the sewage treatment equipment through the electric valve by opening the electric valve for purification treatment.

[0024] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0025] Example 1: By Figure 1-6It is known that a manure separation and collection device for livestock breeding includes a breeding area 1. The manure separation and collection device for livestock breeding also includes a separation device 2, a conveying device 3, and a discharge component 4. The separation device 2 is located inside and below the breeding area 1, and one side extends to the outside of the breeding area 1. The conveying device 3 is located on the separation device 2. The discharge component 4 is located on the side of the separation device 2 away from the breeding area 1. The separation device 2 separates the solid and liquid in the manure, the conveying device 3 conveys the manure, and the discharge component 4 facilitates the discharge of the dried manure.

[0026] In the specific implementation process, it is worth noting that the breeding area 1 in this application document is only for the convenience of describing the installation location and usage of the separation device 2. The separation device 2 separates the liquid and the feces in the feces and collects the separated liquid. The transmission device 3 transmits the feces, and the discharge component 4 monitors the pressure in the separation device 2.

[0027] Furthermore, the separation device 2 includes an installation cylinder 21, a cavity 22, a first filter screen 23, a pull rod 24, a fixing rod 25, a liquid collection cylinder 26, a liquid level sensor 27, an electric valve 28, and a connecting device 29. The installation cylinder 21 is fixedly connected to the bottom of the inner wall of the aquaculture area 1 and extends to the outside of the aquaculture area 1; the cavity 22 is opened at the bottom of the inner wall of the installation cylinder 21; the first filter screen 23 is inserted into the bottom of the inner wall of the installation cylinder 21 through the cavity 22; the pull rod 24 is fixedly connected to one side of the outer wall of the first filter screen 23 and is located inside the cavity 22; the fixing rod 25 passes through the top of the pull rod 24 and is inserted into the bottom of the inner wall of the aquaculture area 1; the liquid collection cylinder 26 is disposed at the position of the installation cylinder 21. Located below the outside of the breeding area 1; a liquid level sensor 27 is fixedly connected to the inner wall of the liquid collection cylinder 26; an electric valve 28 is connected to the bottom of the liquid collection cylinder 26; a connecting device 29 is located on the bottom of the mounting cylinder 21 away from the breeding area 1 and connected to the upper side of the liquid collection cylinder 26; wherein, the mounting cylinder 21 installs the first filter screen 23 through the cavity 22, and replaces and fixes the first filter screen 23 through the pull rod 24 and the fixing rod 25; the liquid collection cylinder 26 collects liquid from the feces, senses and discharges the liquid through the liquid level sensor 27 and the electric valve 28, and transmits the liquid squeezed out of the feces to the liquid collection cylinder 26 through the connecting device 29;

[0028] In the specific implementation process, it is worth noting that when the feces are manually pushed into the installation cylinder 21, the liquid in the feces flows through the first filter screen 23 into the liquid collection cylinder 26. When the liquid level sensor 27 inside the liquid collection cylinder 26 detects that the liquid is about to be full, it activates the electric valve 28 to allow the liquid inside the liquid collection cylinder 26 to flow into the externally connected sewage treatment system. When too much feces adhere to the first filter screen 23, the fixing rod 25 is manually pulled out, and then the first filter screen 23 is pulled out from the cavity 22 through the pull rod 24, which allows for cleaning of the first filter screen 23. The liquid collection cylinder 26 can be pre-embedded. The installation is carried out, and the output end of the electric valve 28 is connected to the sewage treatment system. When the liquid inside the liquid collection cylinder 26 is full, it flows directly into the sewage treatment system through the electric valve 28. The liquid level sensor 27 is model HPT-3051L. The material of the installation cylinder 21 can be set as 304 stainless steel, which has strong corrosion resistance and a relatively balanced strength and toughness. At the same time, a feeding hopper is set on the left end of the installation cylinder 21, which is adapted to the ground of the breeding area 1. The feeding hopper is fixed to the installation cylinder 21 by bolts. When it is necessary to remove the first filter screen 23, the feeding hopper is disassembled, and the left end of the pull rod 24 can be exposed, and the first filter screen 23 can be pulled out. The installation cylinder 21 is also fixed to the ground of the breeding area 1 by bolts.

[0029] Furthermore, the connecting device 29 includes a straight cylinder 291, a gasket 292, a second filter screen 293, and a connecting pipe 294. The straight cylinder 291 is connected to the bottom of the mounting cylinder 21; the gasket 292 is fixedly connected to the inner wall of the straight cylinder 291; the second filter screen 293 is attached to the top of the gasket 292 and is also attached to the inner wall of the straight cylinder 291; the connecting pipe 294 connects the straight cylinder 291 and the liquid collection cylinder 26. The second filter screen 293 is installed through the straight cylinder 291 and the gasket 292, and the second filter screen 293 transmits the liquid flowing out of the squeezed feces to the inside of the liquid collection cylinder 26 through the connecting pipe 294.

[0030] In the specific implementation process, it is worth noting that during the transportation of feces, the feces will be squeezed so that the residual liquid in the feces can flow through the second filter screen 293 and into the liquid collection cylinder 26 through the connecting pipe 294. The second filter screen 293 is placed through the pad ring 292 to facilitate the replacement and cleaning of the second filter screen 293 later. The straight cylinder 291 and the connecting pipe 294 also need to be buried underground.

[0031] Specifically, when using this livestock manure separation and collection device, as the manure is transported through the installation cylinder 21, the liquid in the manure flows into the liquid collection cylinder 26 through the first filter screen 23. When the liquid level sensor 27 inside the liquid collection cylinder 26 senses that the liquid is almost full, it activates the electric valve 28 to allow the liquid inside the liquid collection cylinder 26 to flow into the externally connected sewage treatment system. When too much manure adheres to the first filter screen 23, the operator manually pulls out the fixing rod 25 and then pulls the first filter screen 23 out of the cavity 22 using the pull rod 24 to clean the first filter screen 23. During the manure transport process, the manure is squeezed, allowing the residual liquid in the manure to flow through the second filter screen 293 and into the liquid collection cylinder 26 through the connecting pipe 294. The second filter screen 293 is placed using the gasket ring 292 for easy replacement and cleaning later.

[0032] Example 2: From Figure 1-6 It is known that the transmission device 3 includes a protective shell 31, a servo motor 32, a first bevel gear 33, a second bevel gear 34, and a spiral blade 35. The protective shell 31 is fixedly connected to the inner wall of the mounting cylinder 21. The servo motor 32 is fixedly connected to the top of the mounting cylinder 21 on the side outside the breeding area 1, and its output end passes through the top of the mounting cylinder 21 and the protective shell 31 from top to bottom through a sealed bearing. The first bevel gear 33 is fixedly connected to the output end of the servo motor 32. The second bevel gear 34 is meshed with the outer wall of the first bevel gear 33. One end of the spiral blade 35 passes through the outer wall of the protective shell 31 through a sealed bearing and is fixed to the outer wall of the second bevel gear 34. The other end is rotatably connected to the inner wall of the mounting cylinder 21 through a sealed bearing. The protective shell 31 protects the first bevel gear 33 and the second bevel gear 34. The servo motor 32 drives the spiral blade 35 to rotate through the first bevel gear 33 and the second bevel gear 34 to transport the feces.

[0033] In the specific implementation process, it is worth noting that when the servo motor 32 is started, the output shaft of the servo motor 32 drives the first bevel gear 33 to rotate, the first bevel gear 33 drives the second bevel gear 34 that meshes with it to rotate, and the second bevel gear 34 drives the spiral blade 35 to rotate, thereby conveying the manure in the installation cylinder 21 and transporting the manure to the designated location. The spiral blade 35 can be made of stainless steel, which has strong strength and corrosion resistance. The installation cylinder 21 is provided with a protective mechanism on one side above the inside of the breeding area 1. Specifically, it consists of a protective cover and a hook for fixing the protective cover. The protective cover is rotatably connected to the inner wall of the breeding area 1 by a pin. When it is necessary to clean the manure, the protective cover is rotated and then fixed by the hook. Then, the personnel manually push the manure into the installation cylinder 21 using tools. When it is not necessary to clean, the protective cover is fastened to the bottom of the inner wall of the breeding area 1 to avoid affecting the installation cylinder 21.

[0034] Furthermore, the discharge assembly 4 includes a cover 41, a pressure sensor 42, a mounting plate 43, a telescopic rod 44, and a controller 45. The cover 41 is rotatably connected to the outer wall of the mounting cylinder 21 on the side outside the breeding area 1 via a pin. Multiple pressure sensors 42 are provided, all fixedly connected to the outer wall of the cover 41 near the protective shell 31. The mounting plate 43 is fixedly connected to the top of the mounting cylinder 21 on the side outside the breeding area 1. The telescopic rod 44 is rotatably connected to the bottom of the mounting plate 43 via a pin, and its output end is rotatably connected to the outer wall of the cover 41 via a pin. The controller 45 is fixedly connected to the front of the mounting cylinder 21. The cover 41 and the pressure sensor 42 detect the pressure of the manure inside the mounting cylinder 21, and the controller 45 controls the telescopic rod 44 to drive the cover 41 to open and close.

[0035] In the specific implementation process, it is worth noting that when the feces are transported through the spiral blades 35 in the mounting cylinder 21, the feces gradually move towards the cover 41. At this time, the pressure sensor 42 senses the pressure of the feces transport on the cover 41. During the transport process, the cover 41 will squeeze the feces, squeezing out the residual liquid in the feces. When the pressure sensed by the pressure sensor 42 reaches a certain value, the controller 45 activates the telescopic rod 44, which opens the cover 41, allowing the dry feces to be transported out. If personnel observe that the discharged feces are still wet, the telescopic rod 44 will close the cover 41, continuing the squeezing process to ensure effective separation of the feces and the liquid in the feces, avoiding environmental impact. The pressure sensor 42 is model MPX4115A, and the controller 45 is model S7. -1200, during connection, connect the power supply pin of pressure sensor 42 to a suitable DC power supply, the grounding pin to the system grounding terminal, and the output pin to the analog input port of controller 45. The output signal of pressure sensor 42 is connected to the corresponding channel of the analog input module of PLC. First, according to the hardware configuration and programming requirements of PLC, the analog input module needs to be initialized in the programming software, including selecting the appropriate input signal type, setting parameters such as range and resolution. Then, by writing PLC program, the signal value of pressure sensor 42 in analog input module is read, and according to the preset threshold and control logic, the corresponding control signal is output to digital output module. Multiple pressure sensors 42 are set, and the average value of the monitored pressure can be used to more accurately monitor the pressure of fecal transmission inside the mounting cylinder 21.

[0036] Specifically, based on the above embodiment one, the servo motor 32 is started, and the output shaft of the servo motor 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 drives the second bevel gear 34, which meshes with it, to rotate. The second bevel gear 34 drives the spiral blade 35 to rotate, thereby conveying the feces in the mounting cylinder 21 to the designated location. When the feces are conveyed through the spiral blade 35 in the mounting cylinder 21, the feces gradually move towards the cover 41. At this time, the pressure sensor 42 senses the pressure of the feces conveying on the cover 41. During the conveying process, the cover 41 will squeeze the feces, squeezing out the residual liquid in the feces. When the pressure sensed by the pressure sensor 42 reaches a certain value, the controller 45 starts the telescopic rod 44. The telescopic rod 44 opens the cover 41, and the dry feces can be conveyed out. If the personnel observe that the feces coming out are wet, the telescopic rod 44 drives the cover 41 to close and continue squeezing, ensuring that the feces and the liquid in the feces are effectively separated to avoid affecting the environment.
