This model saves land, transportation turnover costs and labor costs, is easier to achieve intelligent production, and is more effective in preventing and controlling some diseases. The manure cleaning of pigs in buildings preferably adopts a funnel-type sewage discharge design, that is, manure funnels are evenly arranged and installed under the manure-leaking plate. After the manure and urine are collected by the funnel, they are discharged into the environmental protection area through pipes in a timely manner for cleaning. No manual or mechanical manure cleaning is required, the pig house operation and maintenance cost is low, and there is less manure and urine residue in the pig house, and low ammonia residue.

[0003] The existing manure receiving funnel adopts direct discharge, that is, the manure and urine in the pig house are collected by the manure receiving funnel and then directly discharged into the pipe. This method of manure discharge is easy to cause pipe blockage when a lot of manure and urine are produced in the pig house at a certain period of time.

[0007] The valve plate is divided into a natural state and a compressed state. When in the natural state, the four valve plates are supported by the elastic component and are symmetrically tilted, and the inclination is the same as that of the supporting legs.

[0011] As a preferred technical solution of the present invention, the piston assembly includes a plunger axially slidably sleeved in 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 water inlet and outlet holes; the bottom surface of the plunger is axially connected to a guide rod, and the guide rod gap passes through a partition axially fixed in the guide support column, and a spring 2 is axially sleeved on the upper part of the guide rod, and the top end of the spring 2 is connected to the bottom surface of the plunger, and the bottom end thereof is connected to the top surface of the partition; the lower part of the guide rod is vertically connected to four baffle rods at equal intervals in the circumferential direction, and each baffle rod passes through a corresponding straight guide hole longitudinally opened in the lower part of the guide support column;

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Embodiment 1

[0038] In order to solve the technical problems in the background technology, a funnel-type pig house manure discharge equipment is provided as follows:

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

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

[0041] The valve plate 33 is divided into a natural state and a compressed state. When in the natural state, the four valve plates 33 are supported by the elastic component 36 and are symmetrically tilted, and the inclination is the same as that of the supporting legs 32. The bottom edge of the valve plate 33 maintains a gap with the corresponding inner wall of the manure receiving funnel 1, and the nozzle 3422 of the flushing component 34 does not spray water outward; when in the compressed state, the four valve plates 33 are synchronously tilted downward around their respective top edges, and the gap between the bottom edge of the valve plate 33 and the corresponding inner wall of the manure receiving funnel 1 is directly proportional to the pressure, and the elastic component 36 is compressed and stretched downward, driving the four nozzles 3422 of the flushing component 34 to synchronously spray water outward to the front of the corresponding valve plate 33.

[0042] By adopting the above technical solution, the four-leaf valve mechanism 3 arranged in the manure receiving hopper 1 of the device can automatically adapt to the change of the amount of manure and urine in the pig house; in the natural state, the four valve plates 33 are supported by the elastic component 36 to maintain a symmetrical tilted setting, and can temporarily store a small amount of manure and urine; when the amount of manure and urine increases and pressure is generated 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 plates 33 and the inner wall of the manure receiving hopper 1, and the manure and urine intermittently fall 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 compressed state, the elastic component 36 not only stretches downward under the pressure, but also drives the four nozzles 3422 of the flushing component 34 to synchronously spray water outward to the front of the corresponding valve plate 33. This design realizes the automatic flushing function and reduces the need for manual flushing. It not only ensures the cleanliness of the valve plate 33, reduces the generation of harmful gases such as ammonia, improves the environment in the pig house, but also further dilutes feces and urine, prevents pipe blockage, and thus reduces operating costs;

[0044] The provided shielding cone cap 35 can not only evenly guide the feces and urine to each valve plate 33 , but also prevent the feces, urine, dust and other pollutants in the pig house from directly contacting the flushing component 34 .

[0045] Embodiment 2

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

[0047] In this embodiment, if 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, and the side surfaces of the square platform 362 are symmetrically pivotally connected to the middle part of the back side of the corresponding valve plate 33 with a connecting rod 364; the lower part of the guide support column 361 is also axially sleeved with a spring 363, and the top end of the spring 363 is connected to the bottom surface of the mounting plate 31, and the 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, which work together to enable the valve plate 33 to automatically adapt to the pressure changes of the feces and urine volume; when the feces and urine volume is small, the valve plate 33 remains in a natural state, and the inclination is the same as that of the support leg 32. As the feces and urine volume increases, the pressure increases, and the valve plates 33 rotate downward synchronously around their respective top edges, and the gap expands accordingly, and the feces and urine intermittently fall into the three-way sewage pipe 2 below, effectively preventing the pipe from being blocked;

[0049] The pivot connection between the square platform 362 and the connecting rod 364 provides a stable support for the valve plate 33. Under the pressure of feces and urine, the connecting rod 364 can smoothly push the square platform 362 to slide downward along the guide support column 361. At this time, the spring 1 363 is stretched and elongated, which plays a buffering role and reduces the impact on the equipment caused by the sudden change in pressure. At the same time, when the pressure of feces and urine decreases, the spring 1 363 can reset the valve plate 33 under the action of the rebound force.

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

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

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

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

[0054] Preferably, the manure receiving funnel 1, the supporting legs 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 pig house manure discharge equipment, not only the corrosion resistance and wear resistance of the equipment are improved and the maintenance cost is reduced, but also the equipment is made lighter, easier to clean and maintain, while meeting environmental protection requirements and having good cost-effectiveness.

[0056] Embodiment 3

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

[0058] In this embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, the flushing assembly 34 includes four water inlet pipes 341 symmetrically distributed at the corners of the manure receiving funnel 1, and one end of each of the water inlet pipes 341 passes through the annular flange 11, and the other end passes through the corresponding support leg 32, and is connected to the corresponding water 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, and the upper part thereof is symmetrically provided with water outlet holes 3612 in the circumferential direction, and each water outlet hole 3612 is located in the upper middle part of two adjacent water inlet holes 3611; the upper part of the guide support column 361 is sleeved with a water spray assembly 342, and the water spray assembly 342 has four nozzles 3422, and each nozzle 3422 is connected to the corresponding water outlet hole 3612; the inner cavity of the guide support column 361 is axially slidably sleeved with a piston assembly 343;

[0059] When the valve plate 33 is in a natural state, the piston assembly 343 closes the water inlet hole 3611 and the water outlet hole 3612 on the guide support column 361; when the valve plate 33 is in a pressurized state, the square platform 362 of the elastic assembly 36 is pushed down through four connecting rods 364 to drive the piston assembly 343 to open the water inlet hole 3611 and the water outlet hole 3612.

[0060] By adopting the above technical solution, the design of the flushing component 34 realizes the function of non-powered automatic flushing; when the valve plate 33 is in a natural state, the piston component 343 closes the water inlet hole 3611 and the water outlet hole 3612 on the guide support column 361, and the nozzle 3422 does not spray water at this time; and when the amount of feces and urine in the pig house 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 hole 3611 and the water outlet hole 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 hole 3612, so as to realize the flushing of the front of the valve plate 33. This design realizes the function of automatically adjusting the flushing according to the amount of feces 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 holes 3612. This design ensures that when water flows out of the water outlet holes 3612, it can be evenly sprayed on the front of the four valve plates 33, achieving a comprehensive flushing effect, which helps to reduce the feces and urine residue on the valve plate 33 and reduce the risk of pipeline blockage;

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

[0063] like Figure 4 , Figure 5 as well as Figure 7 to Figure 10 As shown, the piston assembly 343 includes a plunger 3431 axially slidably sleeved in 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 hole 3611 and the water outlet hole 3612; the bottom surface of the plunger 3431 is axially connected with a guide rod 3432, and the guide rod 3432 passes through a partition 3433 axially fixed in the guide support column 361, and a spring 2 3434 is axially sleeved on the upper part of the guide rod 3432, and the top end of the spring 2 3434 is connected to the bottom surface of the plunger 3431, and the bottom end is connected to the top surface of the partition 3433; the lower part of the guide rod 3432 is vertically connected with four blocking rods 3435 at equal intervals in the circumferential direction, and each blocking rod 3435 passes through a corresponding straight guide hole 3613 longitudinally opened in the lower part of the guide support column 361;

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

[0065] By adopting the above technical solution, the piston assembly 343 realizes automatic control of the water flow through its structural design; when the valve plate 33 is in a natural state, the plunger 3431 is tightly pressed against the inner top surface of the guide support column 361 under the support of the second spring 3434, thereby effectively closing the water inlet hole 3611 and the water outlet hole 3612, preventing water leakage. This design ensures that when there is no feces and urine pressure, the nozzle 3422 will not spray water for no reason, 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, thereby driving the plunger 3431 to move downward. During this process, the spring 3434 is compressed, and the gap between the plunger 3431 and the inner top surface of the guide support column 361 increases rapidly, thereby opening the water inlet hole 3611 and the water outlet hole 3612. This design enables the nozzle 3422 to quickly respond to the change of feces and urine pressure and spray water to flush the valve plate 33 in time, which can not only ensure the cleaning of the valve plate 33, but also effectively prevent the pipeline from being blocked.

[0067] The matching design of the stopper rod 3435 and the straight guide hole 3613 not only ensures the smooth movement of the plunger 3431, but also prevents the plunger 3431 from deflecting or shaking during the movement; in addition, the elastic design of the second spring 3434 enables 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 automatically spray water as needed, avoiding unnecessary waste; at the same time, since the nozzle 3422 is directly aimed at the front of the valve plate 33 for flushing, the flushing effect is more significant, and the feces and urine residue on the valve plate 33 can be more effectively reduced; this design not only saves water resources, but also reduces the ammonia concentration in the pig house, improves the pig house environment, and helps reduce the occurrence and spread of diseases.

[0069] like Figures 4 to 6 As shown, the water spray assembly 342 includes a cross 3421, and the cross 3421 is axially fixedly sleeved with the top of the guide support column 361 through a circular hole 34211 opened in the middle thereof; the four end faces of the cross 3421 are symmetrically provided with accommodating openings 34212 inwardly, and the end of each accommodating opening 34212 is installed with the spray head 3422 through an adjusting bolt 3424 adapted thereto, and the tail of the spray head 3422 is connected to the corresponding water outlet hole 3612 through a water outlet pipe 3423 adapted thereto.

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

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

[0072] like Figure 6 and Fig.10 As shown, the water outlet pipe 3423 is a flexible hose, and the nozzle 3422 is adjusted to be tilted downward by the adjusting bolt 3424; the front of the nozzle 3422 is a rectangular structure, and a plurality of spray holes 34221 arranged in long strips are provided at equal intervals 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 and enables it to adapt to the flushing requirements at different angles and positions; the nozzle 3422 is tilted downward, which can efficiently flush the front of the valve plate 33 and greatly reduce the amount of water required for flushing; the front of the nozzle 3422 is designed as a rectangular structure, and a plurality of spray holes 34221 arranged in long strips are provided at equal intervals along the short side. This design can increase the flushing area and improve the flushing efficiency.

[0074] like Figure 8 to Figure 10 As shown, a stud 351 is vertically arranged in an integrated manner in the middle of the bottom surface of the shielding cone cap 35 , and the stud 351 is axially threadedly engaged with a screw hole 3614 opened in the middle of the top surface of the guide support column 361 ; the bottom surface of the shielding cone cap 35 covers the nozzle 3422 .

[0075] By adopting the above technical solution, the shielding cone cap 35 is axially threadedly engaged with the screw hole 3614 on the top surface of the guide support column 361 through the stud 351. This detachable design facilitates the disassembly and replacement of the shielding cone cap 35.

[0076] The bottom surface of the shielding cone cap 35 covers the nozzle 3422, which effectively prevents pollutants such as feces, urine, and dust in the pig house from directly contacting the nozzle 3422, and avoids the problem of the nozzle 3422 not being able to work normally due to blockage or contamination; this design extends the service life of the nozzle 3422 and reduces the equipment downtime caused by failure of the nozzle 3422.

[0077] The working principle and use process of the present invention:

[0078] When the present invention is in use, under normal working conditions, the valve plate 33 of the four-leaf valve mechanism 3 maintains a symmetrical tilted setting 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 a standby state. When feces accumulates to a certain extent, pressure is generated on the valve plate 33, causing it to tilt downward synchronously around its respective top edges. The gap between the bottom edge of the valve plate 33 and the inner wall of the feces receiving funnel 1 increases in direct proportion to the increase in pressure, and feces intermittently falls into the three-way sewage pipe 2 below. At the same time, the elastic component 36 is pressed to stretch downward, pushing the piston component 343 downward through the square platform 362, compressing the spring 2 3434, thereby opening the water inlet hole 3611 and the water outlet hole 3612 on the guide support column 361.

[0079] Once the water inlet hole 3611 and the water outlet hole 3612 are opened, the water flow introduced through the water inlet pipe 341 can enter the inner cavity of the guide support column 361, and flow into the nozzle 3422 of the water spray assembly 342 through the water outlet hole 3612. Since the nozzle 3422 is arranged downwardly and has a rectangular structure on the front side, and multiple nozzle holes 34221 are opened at equal intervals along the short side direction, it can evenly spray water mist to the front side of the corresponding valve plate 33, realizing the automatic flushing function.

[0080] After flushing is completed, as the feces are discharged and the pressure on the valve plate 33 is reduced, the elastic component 36 gradually returns to its original state, driving the valve plate 33 back to its natural state. At the same time, the spring 2 3434 pushes the piston component 343 upward, reclosing the water inlet hole 3611 and the water outlet hole 3612, and stopping the water spraying.

[0081] In addition, the bottom surface of the shielding cone cap 35 covers the nozzle 3422, which effectively prevents pollutants such as feces, urine, and dust in the pig house from directly contacting the nozzle 3422, and avoids the problem that the nozzle 3422 cannot work normally due to blockage or contamination; at the same time, the shielding cone cap 35 can also evenly introduce feces and urine to each valve plate 33, and there is almost no feces and urine residue 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 in the protection scope of the present invention.
