Description

Technical Field

[0001] This invention belongs to the technical field of livestock wastewater discharge equipment, and specifically relates to a funnel-type pigsty wastewater discharge device. Background Technology

[0002] Currently, multi-story pig farming is gradually gaining popularity in China. This model saves on land, transportation and labor costs, facilitates intelligent production, and is more effective in controlling certain diseases. For manure removal in multi-story pig farming, a funnel-type sewage discharge design is preferred. This involves evenly arranging manure collection funnels under a slatted floor. Manure is collected through these funnels and promptly discharged into an environmentally friendly cleaning area via pipes. This eliminates the need for manual or mechanical manure removal, resulting in lower pigsty maintenance costs, less residual manure and urine, and lower ammonia levels in the pigsty.

[0003] The existing manure collection funnel uses a direct discharge method, which means that the manure and urine in the pigsty are collected in the manure collection funnel and discharged directly into the pipe. This method of manure discharge is prone to causing pipe blockage when a large amount of manure and urine is produced in the pigsty at a certain time. It requires manual continuous flushing of water into the manure collection funnel to clear the blockage, which increases operating costs. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a funnel-type manure discharge device for pigsties, the specific technical solution of which is as follows:

[0005] The present invention provides a funnel-type manure discharge device for pigsties, including a manure receiving funnel, which is suspended on the frame beam of each layer of pigsty through an annular flange integrally connected at its top opening, and is connected to a three-way sewage pipe suspended directly below it through a straight pipe sleeved at its bottom opening, and also includes a four-leaf valve mechanism disposed inside the manure receiving funnel.

[0006] The four-leaf valve mechanism includes a square mounting plate, which is supported and connected to the inner wall corner of the corresponding manure collection funnel by symmetrically arranged downward-sloping support legs at its four corners; valve plates are provided between adjacent support legs and are adapted to each other, with the top edge of each valve plate pivotally connected to the side edge of the corresponding mounting plate; a guide column is vertically inserted through the middle of the mounting plate, and the four valve plates are synchronously suspended by an elastic component sleeved on the lower part of the guide column; a flushing component is also sleeved on the upper part of the guide column, and the flushing component has four nozzles respectively suspended on the top of the corresponding valve plates; a guide cone cap is axially covered on the top surface of the guide column;

[0007] The valve plates are in a natural state and a pressurized state. In the natural state, the four valve plates are symmetrically tilted under the support of the elastic component, and the tilt angle is the same as that of the support legs. The bottom edge of the valve plate is separated from the inner wall of the corresponding manure funnel, and the nozzles of the flushing component do not spray water outward. In the pressurized state, the four valve plates tilt downward synchronously around their respective top edges. The gap between the bottom edge of the valve plate and the inner wall of the corresponding manure funnel increases proportionally with the pressure. The elastic component extends downward under pressure, causing the four nozzles of the flushing component to spray water outward synchronously to the front of the corresponding valve plate.

[0008] As a preferred embodiment of the present invention, the elastic component includes a square platform axially slidably sleeved on the lower part of the guide support column, and connecting rods are symmetrically pivotally connected between the side of the square platform and the middle of the back of the corresponding valve plate; a spring is also axially sleeved on the lower part of the guide support column, and the top end of the spring is connected to the bottom surface of the mounting plate, and its bottom end is connected to the top surface of the square platform.

[0009] As a preferred embodiment of the present invention, the flushing assembly includes four inlet pipes symmetrically distributed at the corners of the manure collection funnel. One end of each inlet pipe passes through the annular flange, and the other end passes through the corresponding support leg and communicates with a corresponding inlet hole opened on the upper part of the guide column. The guide column is a hollow cylindrical structure with a closed top surface and symmetrically circumferentially shaped outlet holes on its upper part. Each outlet hole is located in the upper part of two adjacent inlet holes. A water spraying assembly is sleeved on the upper part of the guide column, and the water spraying assembly has four nozzles, each nozzle communicating with a corresponding outlet hole. A piston assembly is axially slidably sleeved inside the guide column.

[0010] When the valve plate is in its natural state, the piston assembly closes the water inlet and outlet holes on the guide support column; when the valve plate is under pressure, the square platform of the elastic component is pushed down by the four connecting rods, which drives the piston assembly to open the water inlet and outlet holes.

[0011] As a preferred embodiment of the present invention, the piston assembly includes a plunger axially slidably sleeved within the inner cavity of the guide support column, and the top surface of the plunger abuts against the inner top surface of the guide support column to close the inlet and outlet water holes; a guide rod is axially connected to the bottom surface of the plunger, and the guide rod passes through a partition axially fixed within the guide support column; a second spring is axially sleeved on the upper part of the guide rod, and the top end of the second spring is connected to the bottom surface of the plunger, while its bottom end is connected to the top surface of the partition; four stop rods are vertically connected at equal intervals around the lower part of the guide rod, and each stop rod passes through a corresponding longitudinally opened straight guide hole in the lower part of the guide support column;

[0012] When the valve plate is in its natural state, the square platform of the elastic component is in contact with the stop rod with a gap, the top surface of the plunger is in contact with the inner top surface of the guide column under the support of the second spring, and the stop rod is located at the top of the corresponding straight guide hole; when the valve plate is in a compressed state, the square platform of the elastic component pushes down the stop rod, and drives the plunger to move down to compress the second spring and open the water inlet and water outlet.

[0013] As a preferred embodiment of the present invention, the water spray assembly includes a cross, which is axially fixed to the top of the guide support column through a circular hole in its middle; the four end faces of the cross are respectively provided with accommodating openings, and each end of the accommodating opening is equipped with a nozzle through an adjusting bolt adapted thereto, and the tail of the nozzle is connected to the corresponding water outlet through a water outlet pipe adapted thereto.

[0014] As a preferred embodiment of the present invention, the water outlet pipe is a flexible hose, and the nozzle is adjusted to be inclined downward by the adjusting bolt; the front of the nozzle is a rectangular structure, and multiple elongated spray holes are evenly spaced along its short side.

[0015] As a preferred embodiment of the present invention, a stud is integrally and vertically arranged in the middle of the bottom surface of the guide cone cap, and the stud is axially screwed into a screw hole in the middle of the top surface of the guide support column; the bottom surface of the guide cone cap covers the nozzle.

[0016] As a preferred embodiment of the present invention, the front of the support leg is configured with an arc-shaped raised structure.

[0017] As a preferred embodiment of the present invention, the bottom edge of the valve plate is configured as a downward inclined surface.

[0018] As a preferred embodiment of the present invention, the manure receiving funnel, the supporting leg, and the valve plate are all made of modified PVC plastic.

[0019] The beneficial effects of this invention are:

[0020] The four-leaf valve mechanism in the manure receiving funnel of this invention can automatically adapt to changes in the amount of manure and urine in the pigsty. In its natural state, the four valve plates are symmetrically tilted under the support of the elastic components, which can temporarily store a small amount of manure and urine. When the amount of manure and urine increases and exerts pressure on the valve plates, the valve plates will tilt downward synchronously around their respective top edges, increasing the gap between the bottom edge of the valve plate and the inner wall of the manure receiving funnel. The manure and urine will fall intermittently into the three-way drain pipe below, thereby effectively preventing pipe blockage.

[0021] When the valve plate is subjected to the pressure of feces and urine and enters the pressurized state, the elastic component not only extends downward under pressure, but also drives the four nozzles of the flushing component to spray water outward synchronously to the front of the corresponding valve plate. This design realizes the automatic flushing function, reduces the need for manual flushing, ensures the cleanliness of the valve plate, reduces the generation of harmful gases such as ammonia, improves the environment in the pigsty, further dilutes the feces and urine, prevents pipe blockage, and thus reduces operating costs.

[0022] The installed guide cone caps can not only evenly guide the manure and urine onto each valve plate, but also prevent pollutants such as manure, urine, and dust in the pigsty from directly contacting the flushing components. Attached Figure Description

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] Example 1

[0038] To address the technical problems in the background section, a funnel-type manure discharge device for pigsties is provided as follows:

[0039] Combination Figures 1-4 as well as Figures 10-12 As shown, a funnel-type pigsty manure discharge device includes a manure receiving funnel 1, which is suspended on the frame beam 4 of each pigsty through an annular flange 11 integrally connected at its top opening, and is connected to the three-way sewage pipe 2 suspended directly below it through a straight pipe 12 sleeved at its bottom opening. It also includes a four-leaf valve mechanism 3 set inside the manure receiving funnel 1.

[0040] The four-leaf valve mechanism 3 includes a square mounting plate 31. The mounting plate 31 is supported and connected to the inner wall corner of the corresponding manure funnel 1 by support legs 32 that are symmetrically arranged downwards at its four corners. A valve plate 33 is provided between adjacent support legs 32 and is adapted to them. The top edge of each valve plate 33 is pivotally connected to the side of the corresponding mounting plate 31. A guide column 361 is vertically inserted through the middle of the mounting plate 31. The four valve plates 33 are synchronously suspended by an elastic component 36 sleeved on the lower part of the guide column 361. A flushing component 34 is also sleeved on the upper part of the guide column 361. The flushing component 34 has four nozzles 3422 that are respectively suspended on the top of the corresponding valve plates 33. A guide cone cap 35 is axially covered on the top surface of the guide column 361.

[0041] The valve plates 33 are in a natural state and a pressurized state. In the natural state, the four valve plates 33 are symmetrically tilted under the support of the elastic component 36, and the tilt angle is the same as that of the support leg 32. The bottom edge of the valve plate 33 is separated from the inner wall of the corresponding manure funnel 1, and the nozzles 3422 of the flushing component 34 do not spray water outward. In the pressurized state, the four valve plates 33 tilt downward synchronously around their respective top edges. The gap between the bottom edge of the valve plate 33 and the inner wall of the corresponding manure funnel 1 increases proportionally with the pressure. The elastic component 36 extends downward under pressure, causing the four nozzles 3422 of the flushing component 34 to spray water outward synchronously to the front of the corresponding valve plate 33.

[0042] By adopting the above technical solution, the four-leaf valve mechanism 3 set in the manure receiving funnel 1 can automatically adapt to the changes in the amount of manure and urine in the pigsty. In the natural state, the four valve plates 33 are symmetrically tilted under the support of the elastic component 36, which can temporarily store a small amount of manure and urine. When the amount of manure and urine increases and puts pressure on the valve plates 33, the valve plates 33 will tilt downward synchronously around their respective top edges, increasing the gap between the bottom edge of the valve plate 33 and the inner wall of the manure receiving funnel 1. The manure and urine fall intermittently into the three-way sewage pipe 2 below, thereby effectively preventing pipe blockage.

[0043] When the valve plate 33 is subjected to the pressure of feces and urine and enters the pressurized state, the elastic component 36 not only extends downward under pressure, but also drives the four nozzles 3422 of the flushing component 34 to spray water outward synchronously to the front of the corresponding valve plate 33. This design realizes the automatic flushing function, reduces the need for manual flushing, ensures the cleanliness of the valve plate 33, reduces the generation of harmful gases such as ammonia, improves the environment in the pigsty, further dilutes the feces and urine, prevents pipe blockage, and thus reduces operating costs.

[0044] The set guide cone cap 35 can not only evenly introduce manure and urine onto each valve plate 33, but also prevent pollutants such as manure, urine, and dust in the pigsty from directly contacting the flushing component 34.

[0045] Example 2

[0046] Combination Figure 2 , Figure 3 as well as Figure 10 , Figure 11 As shown, based on the above embodiments, this embodiment further provides the following:

[0047] In this embodiment, as Figure 3As shown, the elastic component 36 includes a square platform 362 axially slidably sleeved on the lower part of the guide support column 361. The side of the square platform 362 is symmetrically pivotally connected to the middle of the back of the valve plate 33. A spring 363 is also axially sleeved on the lower part of the guide support column 361. The top end of the spring 363 is connected to the bottom surface of the mounting plate 31, and its bottom end is connected to the top surface of the square platform 362.

[0048] By adopting the above technical solution, the elastic component 36 is composed of a square platform 362, a connecting rod 364, and a spring 363. They work together to enable the valve plate 33 to automatically adapt to the pressure changes of the amount of feces and urine. When the amount of feces and urine is small, the valve plate 33 remains in its natural state with the same inclination as the support leg 32. As the amount of feces and urine increases, the pressure increases, and the valve plate 33 tilts downward synchronously around its top edge, and the gap widens accordingly. The feces and urine fall intermittently into the three-way drain pipe 2 below, effectively preventing pipe blockage.

[0049] The pivotal connection between the square platform 362 and the connecting rod 364 provides stable support for the valve plate 33. Under the action of fecal and urinary pressure, the connecting rod 364 can smoothly push the square platform 362 to slide down along the guide column 361. At this time, the spring 363 is stretched, which plays a buffering role and reduces the impact on the equipment caused by sudden pressure changes. At the same time, when the fecal and urinary pressure decreases, the spring 363 can reset the valve plate 33 under the action of rebound force.

[0050] like Figure 2 , Figure 10 and Figure 11 As shown, the front of the support leg 32 is designed with an arc-shaped raised structure.

[0051] By adopting the above technical solution, the support strength of the support leg 32 can be improved, and the feces and urine falling on the support leg 32 can be better slid onto the valve plate 33, effectively reducing the feces and urine residue on the support leg 32.

[0052] like Figure 2 , Figure 3 and Figure 10 As shown, the bottom edge of the valve plate 33 is set as a downward inclined surface.

[0053] By adopting the above technical solution, it is helpful for feces and urine to enter the bottom of the receiving funnel 1 more smoothly, and reduce the retention of feces and urine at the bottom of the valve plate 33.

[0054] Preferably, the manure receiving funnel 1, the support leg 32, and the valve plate 33 are all made of modified PVC plastic.

[0055] By adopting the above technical solution and using modified PVC plastic as the key component material of the funnel-type pigsty manure discharge equipment, not only is the corrosion resistance and wear resistance of the equipment improved and maintenance costs reduced, but the equipment is also made lighter, easier to clean and maintain, and meets environmental protection requirements, thus having good cost-effectiveness.

[0056] Example 3

[0057] Combination Figure 2 as well as Figures 4 to 10 As shown, based on the above embodiments, this embodiment further provides the following:

[0058] In this embodiment, as Figure 2 , Figure 4 and Figure 5 As shown, the flushing assembly 34 includes four inlet pipes 341 symmetrically distributed at the bends of the manure collection funnel 1. One end of each inlet pipe 341 passes through the annular flange 11, and the other end passes through the corresponding support leg 32, communicating with the corresponding inlet hole 3611 opened on the upper part of the guide support column 361. The guide support column 361 is a hollow cylindrical structure with a closed top surface. It has symmetrically circumferentially circumferentially symmetrically opened outlet holes 3612 on its upper part, and each outlet hole 3612 is located in the upper part of two adjacent inlet holes 3611. A water spray assembly 342 is sleeved on the upper part of the guide support column 361, and the water spray assembly 342 has four nozzles 3422, each nozzle 3422 communicating with the corresponding outlet hole 3612. A piston assembly 343 is axially slidably sleeved in the inner cavity of the guide support column 361.

[0059] When the valve plate 33 is in its natural state, the piston assembly 343 closes the water inlet 3611 and water outlet 3612 on the guide support column 361; when the valve plate 33 is under pressure, the square platform 362 of the elastic component 36 is pushed down by the four connecting rods 364, which drives the piston assembly 343 to open the water inlet 3611 and water outlet 3612.

[0060] By adopting the above technical solution, the design of the flushing component 34 realizes the function of automatic flushing without power. When the valve plate 33 is in the natural state, the piston component 343 closes the water inlet 3611 and water outlet 3612 on the guide support column 361, and the nozzle 3422 does not spray water at this time. When the amount of manure and urine in the pigsty increases, causing the valve plate 33 to tilt downward under pressure, the square platform 362 of the elastic component 36 pushes the piston component 343 downward through the connecting rod 364, thereby opening the water inlet 3611 and water outlet 3612. In this way, external tap water or circulating water can enter the inner cavity of the guide support column 361 through the water inlet pipe 341 and flow to the nozzle 3422 through the water outlet 3612 to achieve flushing of the front of the valve plate 33. This design realizes the function of automatically adjusting the flushing according to the amount of manure and urine, avoiding unnecessary waste.

[0061] The four nozzles 3422 of the flushing assembly 34 are symmetrically distributed at the corners of the manure receiving funnel 1 and are connected to the corresponding water outlet 3612. This design ensures that when water flows out from the water outlet 3612, it can be sprayed evenly onto the front of the four valve plates 33, achieving a comprehensive flushing effect. This helps to reduce the residue of feces and urine on the valve plates 33 and reduce the risk of pipe blockage.

[0062] The timely flushing function of the flushing component 34 helps to keep the inside of the valve plate 33 and the manure receiving funnel 1 clean, reducing the accumulation of manure and urine and the risk of blockage. This helps to improve sewage discharge efficiency, ensure that manure and urine in the pigsty can be discharged in a timely manner, reduce ammonia residue, and improve the pigsty environment.

[0063] like Figure 4 , Figure 5 as well as Figures 7-10 As shown, the piston assembly 343 includes a plunger 3431 axially slidably sleeved within the inner cavity of the guide support column 361, and the top surface of the plunger 3431 abuts against the inner top surface of the guide support column 361 to close the water inlet 3611 and the water outlet 3612; a guide rod 3432 is axially connected to the bottom surface of the plunger 3431, and the guide rod 3432 passes through the partition plate 3433 axially fixed within the guide support column 361; a second spring 3434 is axially sleeved on the upper part of the guide rod 3432, and the top end of the second spring 3434 is connected to the bottom surface of the plunger 3431, and its bottom end is connected to the top surface of the partition plate 3433; four stop rods 3435 are vertically connected at equal intervals in the circumferential direction on the lower part of the guide rod 3432, and each stop rod 3435 passes through a straight guide hole 3613 opened longitudinally at the lower part of the guide support column 361.

[0064] When the valve plate 33 is in its natural state, the square platform 362 of the elastic component 36 is in clearance contact with the stop rod 3435, and the top surface of the plunger 3431 abuts against the inner top surface of the guide column 361 under the support of the second spring 3434, and the stop rod 3435 is located at the top of the corresponding straight guide hole 3613; when the valve plate 33 is in a compressed state, the square platform 362 of the elastic component 36 pushes down the stop rod 3435, and drives the plunger 3431 to move down to compress the second spring 3434, thereby opening the water inlet 3611 and the water outlet 3612.

[0065] By adopting the above technical solution, the piston assembly 343 achieves automatic control of water flow through its structural design. When the valve plate 33 is in its natural state, the plunger 3431 is tightly pressed against the inner top surface of the guide column 361 under the support of the spring 3434, thereby effectively closing the water inlet 3611 and the water outlet 3612 and preventing water leakage. This design ensures that the nozzle 3422 will not spray water unnecessarily when there is no pressure from feces or urine, thereby saving water resources.

[0066] When the valve plate 33 is pressed down by the pressure of feces and urine, the square platform 362 of the elastic component 36 quickly pushes the stop rod 3435 through the connecting rod 364, which in turn drives the plunger 3431 to move down. During this process, the spring 3434 is compressed, and the gap between the plunger 3431 and the inner top surface of the guide rod 361 increases rapidly, thereby opening the water inlet 3611 and the water outlet 3612. This design allows the nozzle 3422 to respond quickly to changes in the pressure of feces and urine and spray water to flush the valve plate 33 in a timely manner, which can not only keep the valve plate 33 clean, but also effectively prevent pipe blockage.

[0067] The design of the stop lever 3435 and the straight guide hole 3613 not only ensures the smooth movement of the plunger 3431, but also prevents the plunger 3431 from shifting or shaking during the movement; in addition, the elastic design of the second spring 3434 allows the plunger 3431 to quickly return to its original position after the pressure on the valve plate 33 is reduced.

[0068] The automatic control function of the piston assembly 343 enables the nozzle 3422 to spray water automatically as needed, avoiding unnecessary waste. At the same time, since the nozzle 3422 directly sprays water onto the front of the valve plate 33, the rinsing effect is more significant, and it can more effectively reduce the residue of feces and urine on the valve plate 33. This design not only saves water resources, but also reduces the ammonia concentration in the pigsty, improves the pigsty environment, and helps reduce the occurrence and spread of diseases.

[0069] like Figures 4-6 As shown, the water spray assembly 342 includes a cross 3421, which is axially fixed to the top of the guide column 361 through a circular hole 34211 in its middle. The four end faces of the cross 3421 are respectively provided with accommodating openings 34212 symmetrically inward. Each end of the accommodating opening 34212 is equipped with a nozzle 3422 through an adjusting bolt 3424, and the tail of the nozzle 3422 is connected to the corresponding water outlet 3612 through a water outlet pipe 3423.

[0070] By adopting the above technical solution, the water spray assembly 342, through the design of the cross 3421, evenly distributes four nozzles 3422 above the corresponding valve plate 33. This layout ensures that when the valve plate 33 is pressed down by fecal and urine pressure, the nozzles 3422 can accurately aim at the front of the valve plate 33 for water cleaning. Since the position of the nozzles 3422 matches the tilt angle of the valve plate 33, the water spray can directly wash away the fecal and urine residue on the valve plate 33, improving cleaning efficiency.

[0071] The nozzle 3422 in the water spray assembly 342 is installed at the end of the receiving port 34212 of the cross 3421 by adjusting bolt 3424. This design allows the spray angle and spray volume of the nozzle 3422 to be adjusted according to actual needs.

[0072] like Figure 6 and Figure 10 As shown, the water outlet pipe 3423 is a flexible hose, and the nozzle 3422 is adjusted to be inclined downward by the adjusting bolt 3424; the front of the nozzle 3422 is a rectangular structure, and multiple elongated spray holes 34221 are evenly spaced along its short side.

[0073] By adopting the above technical solution, the water outlet pipe 3423 is designed as a flexible hose, which further enhances the flexibility of the nozzle 3422, enabling it to adapt to the rinsing needs of different angles and positions. The nozzle 3422 is set at an angle downward, which can efficiently rinse the front of the valve plate 33 and greatly reduce the amount of water required for rinsing. The front of the nozzle 3422 is designed as a rectangular structure, and multiple elongated spray holes 34221 are evenly spaced along the short side. This design can increase the rinsing area and improve the rinsing efficiency.

[0074] like Figures 8-10 As shown, a stud 351 is integrally and vertically arranged in the middle of the bottom surface of the guide cone cap 35. The stud 351 is axially screwed into the screw hole 3614 opened in the middle of the top surface of the guide support column 361. The bottom surface of the guide cone cap 35 covers the nozzle 3422.

[0075] By adopting the above technical solution, the guide cone cap 35 is axially screwed into the screw hole 3614 on the top surface of the guide support column 361 through the stud 351. This detachable design makes it easy to disassemble and replace the guide cone cap 35.

[0076] The bottom surface of the guide cone cap 35 covers the nozzle 3422, effectively preventing pollutants such as manure, urine, and dust in the pigsty from directly contacting the nozzle 3422, thus avoiding the problem of the nozzle 3422 failing to work properly due to blockage or contamination. This design extends the service life of the nozzle 3422 and reduces equipment downtime caused by nozzle 3422 failure.

[0077] Working principle and usage process of this invention:

[0078] In operation, under normal working conditions, the valve plate 33 of the four-leaf valve mechanism 3 is symmetrically tilted under the support of the elastic component 36. At this time, the nozzle 3422 of the flushing component 34 does not spray water, and the equipment is in standby mode. When the feces accumulate to a certain extent, pressure is generated on the valve plate 33, causing it to tilt downward synchronously around its top edge. The gap between the bottom edge of the valve plate 33 and the inner wall of the feces receiving funnel 1 increases proportionally with the increase of the pressure, and the feces intermittently fall into the three-way drain pipe 2 below. At the same time, the elastic component 36 extends downward under pressure, pushing the piston component 343 downward through the square platform 362, compressing the spring 3434, thereby opening the water inlet 3611 and water outlet 3612 on the guide support column 361.

[0079] Once the inlet hole 3611 and outlet hole 3612 are opened, the water introduced through the inlet pipe 341 enters the inner cavity of the guide column 361 and flows into the nozzle 3422 of the water spray assembly 342 through the outlet hole 3612. Since the nozzle 3422 is inclined downward and has a rectangular structure on the front, with multiple spray holes 34221 evenly spaced along the short side, it can evenly spray water mist onto the front of the corresponding valve plate 33, realizing the automatic flushing function.

[0080] After flushing, as the feces are discharged and the pressure on the valve plate 33 decreases, the elastic component 36 gradually returns to its original shape, causing the valve plate 33 to return to its natural state. At the same time, the spring 3434 pushes the piston assembly 343 upward, reclosing the water inlet hole 3611 and the water outlet hole 3612, stopping the water spraying.

[0081] In addition, the bottom surface of the guide cone cap 35 covers the nozzle 3422, which effectively prevents pollutants such as feces, urine, and dust in the pigsty from directly contacting the nozzle 3422, avoiding the problem that the nozzle 3422 cannot work properly due to blockage or contamination; at the same time, the guide cone cap 35 can also evenly introduce feces and urine onto each valve plate 33, with almost no feces and urine residue on itself.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
