Abstract
Description
Technical Field
[0001] This invention belongs to the field of farmyard manure fermentation and fertilization equipment, specifically relating to an automatic timed declogging and filtration device for farmyard manure fermentation and fertilization in terraced fields. Background Technology
[0002] Currently, farmyard manure is generally composted and fermented before being applied to the land, which is labor-intensive. With the aging of rural populations and the phenomenon of hollowed-out villages, especially in mountainous terraced fields, fertilizer is transported by carrying it on shoulders and backs. Farmers rarely use farmyard manure anymore, and instead use large amounts of chemical fertilizers, causing soil compaction, soil degradation, and the inability of the soil to improve its fertility on its own.
[0003] Applying farmyard manure to fields can not only improve the soil, increase soil fertility, improve crop growth quality, and produce organic and ecological agricultural products, but also reduce the waste of farmyard manure resources and pollution to the living environment.
[0004] Therefore, it is necessary to reform the fertilization methods of farmyard manure in mountain terraces. This can be achieved by significantly reducing the labor and cost input for farmyard manure application and lowering the labor intensity, thereby increasing the application of farmyard manure in terraces and correspondingly reducing the use of chemical fertilizers. Summary of the Invention
[0005] In order to solve the above-mentioned technical problems, the present invention proposes an automatic timed filtration device for fermenting and applying farmyard manure in terraced fields. This device greatly simplifies the application of farmyard manure in mountainous terraced fields. Combined with fertigation technology, it enables unmanned application of farmyard manure, increases soil fertility, loosens the soil, significantly saves labor, and has low input costs.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:
[0007] An automatic timed declogging and filtration device for fermenting farmyard manure in terraced fields includes a fermentation tank for fermenting farmyard manure, which is set at a high position in the terraced field. A filter screen is installed in the lower part of the fermentation tank, and a liquid supply pipe for conveying the fermentation liquid of farmyard manure is provided in the lower part of the side wall of the fermentation tank. The liquid supply pipe is connected to a declogging and filtration mechanism.
[0008] The clogging-removing filtration mechanism includes a clogging-removing filter cylinder and a sealing cap. The sealing cap and the clogging-removing filter cylinder are detachably connected, and a cavity is left between the clogging-removing filter cylinder and the sealing cap. A self-rotating filter body for filtering farmyard manure fermentation liquid is also installed between the clogging-removing filter cylinder and the sealing cap. An outlet communicating with the filter body is opened in the middle of the sealing cap. The outlet is connected to a fertilizer liquid pipe for delivering farmyard manure fermentation liquid to the terraced soil. An inlet connected to a supply pipe is provided on one side of the clogging-removing filter cylinder.

A clogging-removing component is provided on the clogging-removing pipe for automatically and periodically discharging debris that is clogging the filter body.
[0009] This invention involves fermenting farmyard manure in a fermentation tank. The resulting fermented material undergoes initial solid-liquid separation through a filter screen. The resulting farmyard manure fermentation liquid flows into a declogging filtration mechanism via a supply pipe. The filter body in the declogging filtration mechanism filters the farmyard manure fermentation liquid again before sending it to the water-saving irrigation network through the fertilizer pipe for integrated water and fertilizer irrigation of terraced crops. At the same time, to prevent solid impurities in the farmyard manure fermentation liquid from clogging the filter body, a declogging component is set up to automatically and periodically discharge the debris that clogs the filter body.

[0011] To enhance the sealing performance of the unclogging filter mechanism, in a preferred embodiment of the present invention, the sealing cover is further provided with a slot, the slot being located inside the inner thread, and the unclogging filter cartridge is provided with a fitting plate that matches the slot.
[0012] To achieve automatic rotation of the filter body and reduce clogging, in a preferred embodiment of the present invention, the filter body includes a filter screen frame, a cylindrical filter screen installed in the middle of the filter screen frame, impellers installed at both ends of the filter screen frame, a hollow convex ring fixedly connected to one end of the filter screen frame, and a convex cylinder fixedly connected to the other end. The hollow convex ring is rotatably installed in the left groove provided at the center of the sealing cover, and the convex cylinder is rotatably installed in the right groove provided at the center of the clogging-removing filter cartridge. The liquid outlet end of the liquid inlet is connected to a Y-shaped nozzle, and the two liquid outlet ends of the Y-shaped nozzle are located obliquely above the impellers. The liquid flowing out of the Y-shaped nozzle impacts the impellers, causing the filter screen frame to rotate.
[0013] To achieve automatic and timed discharge of debris clogging the filter, in a preferred embodiment of the present invention, the unclogging assembly includes a valve, a lever, a gravity tank, a counterweight, a pressure regulating valve, a liquid delivery pipe, a liquid return pipe, and a liquid drain pipe. The valve and the pressure regulating valve are mounted on the unclogging pipe, with the pressure regulating valve located downstream of the valve. A lever is fixed to the valve knob, and the two ends of the lever are respectively connected to the gravity tank and the counterweight. The liquid outlet is connected to the gravity tank through the liquid delivery pipe. The unclogging section between the valve and the pressure regulating valve is connected to the gravity tank through the liquid return pipe and the liquid drain pipe, respectively, with the liquid drain pipe located below the liquid return pipe.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] Example
[0023] Please see the appendix Figure 1-4As shown, the automatic timed declogging and filtration device for fermented farmyard manure in terraced fields in this embodiment includes a fermentation tank 1 for fermenting farmyard manure, located at a high position in the terraced field. A filter screen 2 is installed in the lower part of the fermentation tank 1, and a supply pipe 3 for conveying the fermentation liquid of farmyard manure is provided on the lower part of the side wall of the fermentation tank 1. The supply pipe 3 is connected to a declogging and filtration mechanism. The declogging and filtration mechanism includes a declogging filter cylinder 4 and a sealing cover 5. The sealing cover 5 is detachably connected to the declogging filter cylinder 4, and a cavity is left between the declogging filter cylinder 4 and the sealing cover 5. A self-rotating filter body for filtering farmyard manure fermentation liquid is also installed between the sealing caps 5. An outlet 8, communicating with the filter body, is opened in the middle of the sealing cap 5. The outlet 8 is connected to a fertilizer pipe 21 for delivering farmyard manure fermentation liquid to the terraced soil. An inlet 6, connected to the supply pipe 3, is located on one side of the unblocking filter cylinder 4. An unblocking port 7 is located on the side of the unblocking filter cylinder 4 opposite to the inlet 6. The unblocking port 7 is connected to an unblocking pipe 20, which is equipped with an unblocking component for automatically and periodically discharging debris clogging the filter body. Reinforcing ribs are provided at the bottom of the filter screen 2.
[0024] In this embodiment, farmyard manure is placed in fermentation tank 1 for fermentation. The fermented material is initially separated into solid and liquid by filter screen 2. The resulting farmyard manure fermentation liquid flows into the declogging filtration mechanism through the liquid supply pipe 3. The filter body in the declogging filtration mechanism filters the farmyard manure fermentation liquid again and then sends it to the water-saving irrigation network through fertilizer pipe 21 for integrated water and fertilizer irrigation of terraced crops. At the same time, in order to prevent solid impurities in the farmyard manure fermentation liquid from clogging the filter body, a declogging component is set up to automatically and timedly discharge the debris that clogs the filter body.
[0025] Specifically, in order to facilitate the replacement and maintenance of the internal components of the unclogging filter mechanism, the sealing cover 5 is threadedly connected to the unclogging filter cylinder 4, the sealing cover 5 is provided with an inner thread 10, and the unclogging filter cylinder 4 is provided with an outer thread 9 that matches the inner thread 10.
[0026] Specifically, in order to enhance the sealing performance of the unclogging filter mechanism, the sealing cover 5 is also provided with a slot 12, which is located inside the inner thread 10, and the unclogging filter cartridge 4 is provided with a insert 11 that matches the slot 12.
[0027] Specifically, in order to achieve automatic rotation of the filter body and reduce the occurrence of filter body clogging, in a preferred embodiment of the present invention, the filter body includes a filter screen frame 15, a cylindrical filter screen 16 installed in the middle of the filter screen frame 15, impellers 17 installed at both ends of the filter screen frame 15, a hollow convex ring 18 fixedly connected to one end of the filter screen frame 15, and a convex cylinder 19 fixedly connected to the other end. The hollow convex ring 18 is rotatably installed in the left groove 14 provided at the center of the sealing cover 5, and the convex cylinder 19 is rotatably installed in the right groove 13 provided at the center of the clogging removal filter cartridge 4. The liquid outlet of the liquid inlet 6 is connected to a Y-shaped nozzle 30. The two liquid outlets of the Y-shaped nozzle 30 are located obliquely above the impellers 17. The liquid flowing out of the Y-shaped nozzle 30 impacts the impellers 17 and drives the filter screen frame 15 to rotate.
[0028] Specifically, to achieve automatic timed discharge of debris clogging the filter, the unclogging assembly includes a valve 22, a lever 23, a gravity tank 24, a counterweight 25, a pressure regulating valve 26, a liquid delivery pipe 27, a liquid return pipe 28, and a drain pipe 29. The valve 22 and pressure regulating valve 26 are mounted on the unclogging pipe 20, with the pressure regulating valve 26 downstream of the valve 22. The lever 23 is fixed to the knob of the valve 22, and both ends of the lever 23 are connected to the gravity tank 24 and the counterweight 25, respectively. The liquid outlet 8 is connected to the gravity tank 24 via the liquid delivery pipe 27. The section of the unclogging pipe 20 between the valve 22 and the pressure regulating valve 26 is connected to the gravity tank 24 via the liquid return pipe 28 and the drain pipe 29, respectively. The drain pipe 29 is located below the liquid return pipe 28. The liquid delivery pipe 27 and the liquid return pipe 28 can inject liquid into the gravity tank 24, and the liquid inside the gravity tank 24 can be discharged through the drain pipe 29. The midpoint of lever 23 is located on valve 22. According to the principle of lever 23, the weight of counterweight 25 is greater than the weight of empty gravity tank 24. Counterweight 25 moves downward and opens valve 22 through lever 23, so that valve 22 is in the open state. As the liquid level in gravity tank 24 reaches the set height, it exceeds the weight of counterweight 25. Gravity tank 24 moves downward and closes valve 22 through lever 23, so that valve 22 is in the closed state.
[0029] The working principle of the automatic timed unclogging and filtration device for fermentation and fertilization of farmyard manure in terraced fields of the present invention is as follows: Farmyard manure in the fermentation tank 1 at a high position in the mountain terraced fields undergoes fermentation treatment. The resulting fermented material undergoes initial solid-liquid separation by the filter screen 2. The resulting fermented manure liquid flows into the Y-shaped spray pipe 30 through the supply pipe 3. The impeller 17 drives the filter body to rotate under the impact of the liquid flowing out of the Y-shaped spray pipe 30. The unclogging port 7 is not higher than the outlet 8. After the fertilizer liquid flows through the filter body, it enters the unclogging pipe 20. At this time, because the weight of the counterweight 25 is greater than the weight of the empty gravity tank 24, the counterweight 25 opens the valve 22 through the lever 23. After passing through the pre-adjusted pressure regulating valve 26, pressure is formed in the unclogging pipe 20. Under the pressure, the return pipe 28 injects liquid into the gravity tank 24. As the liquid level in the gravity tank 24 reaches the set height and exceeds the weight of the counterweight 25, the valve 22 closes. The fertilizer liquid enters the cylindrical filter... The liquid flows from the outlet 8 into the fertilizer pipe 21 and enters the integrated water and fertilizer water-saving network. At the same time, some of the fertilizer solution at the outlet 8 is injected into the gravity tank 24 through the delivery pipe 27 due to the pressure of the fertilizer pipe 21. Water is continuously injected into the gravity tank 24 to keep the valve 22 closed. The excess liquid in the gravity tank 24 flows into the drain pipe 20 and is directly discharged to the terraced fields. When the surface of the cylindrical filter screen 16 is blocked, the pressure in the fertilizer pipe 21 decreases, and the flow rate from the delivery pipe 27 into the gravity tank 24 is less than the flow rate from the drain pipe 29. As the liquid level in the gravity tank 24 falls below the set height, it is less than the weight of the counterweight 25. The counterweight 25 opens the valve 22 through the lever 23. Under the action of the rotation of the filter body and the flushing action of the liquid, the blockage impurities are removed from the filter body and flow out with the fertilizer solution through the drain pipe 20. The above principle process is repeated, and the fertilizer solution filtered by the filter body enters the fertilizer pipe 21 for normal fertilization.
[0030] 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.
