Abstract
Description
Technical Field
[0001] This invention relates to the technical field of fertilization equipment, specifically a filtration fertilization device without an additional power source. Background Technology
[0002] Against the backdrop of increasingly prominent contradictions between water supply and demand, vigorously developing water-saving irrigation and fertilization technologies to achieve efficient utilization of water and fertilizer resources has become an inevitable choice for ensuring regional food security and promoting green agricultural development. Currently, water-saving irrigation technologies such as drip irrigation and subsurface irrigation have been widely promoted and applied in agricultural production due to their significant water-saving effects. These water-saving irrigation technologies are usually combined with fertilization to form an integrated water and fertilizer irrigation system, which can accurately deliver fertilizer to the crop roots with irrigation water, greatly improving fertilizer utilization and reducing resource waste and environmental pollution.
[0003] However, in practical applications of irrigation and fertilization, agricultural irrigation water sources are mostly natural sources such as rivers and wells, which contain a large amount of solid particles such as silt. During irrigation and fertilization operations, the water flow carrying silt into the fertilizer tank will enter the core power equipment such as water pumps and centrifugal pumps, as well as the subsequent pipeline system, along with the irrigation water-fertilizer mixture. Over long-term operation, silt easily accumulates and adheres to the internal flow channels, impellers, and pipeline interfaces of the equipment, leading to narrowing of the flow channels, impeller wear, and consequently, a decrease in the output of water pumps and centrifugal pumps, increased energy consumption, and even equipment jamming and malfunctions, significantly reducing irrigation and fertilization efficiency and increasing equipment maintenance costs and downtime losses. Summary of the Invention
[0004] The purpose of this invention is to provide a filtration and fertilization device without an additional power source, which can filter impurities in raw water, solve the problem that impurities contained in silt and fertilizer can easily cause the equipment to jam and fail to work properly, ensure the stability of the fertilization equipment after long-term operation, and improve the service life of the fertilization equipment.
[0005] To achieve the above objectives, the invention employs the following technical solution:
[0006] A filtration and fertilization device without an additional power source includes a base plate and a medicine tank mounted on the base plate. The base plate is equipped with a cyclone filter and a disc filter. It also includes an inlet pipe connected to the inlet of the cyclone filter, a water supply pipe connected to the outlet of the cyclone filter and the inlet of the disc filter, and an irrigation pipe connected to the outlet of the disc filter. The bottom of the medicine tank has a fertilizer outlet, the irrigation pipe has a proportioning pump, the top of the medicine tank has a water inlet connected to the water supply pipe, the side of the medicine tank has a fertilizer inlet, and the fertilizer outlet has a drug delivery pipe connected to the proportioning pump.
[0007] Furthermore, the water supply pipe, the drug delivery pipe, and the connecting pipe are respectively equipped with a first valve, a second valve, and a third valve, the drug delivery pipe is equipped with a drainage pipe, and the drainage pipe is equipped with a fourth valve.
[0008] Furthermore, it also includes a drain tank connected to the bottom of the cyclone filter, and a return pipe connecting the drain tank and the water supply pipe, wherein the drain tank is equipped with a drain pipe.
[0009] Furthermore, the sewage tank is equipped with a first filter plate, a second filter plate, and a third filter plate, which divide the tank into a first filter chamber, a second filter chamber, a third filter chamber, and a fourth filter chamber, respectively. The return pipe is connected to the second filter chamber and the fourth filter chamber, respectively. The first filter plate, the second filter plate, and the third filter plate are respectively provided with a first filter hole, a second filter hole, and a third filter hole. The inner diameters of the first filter hole and the third filter hole are equal, and the inner diameters of the first filter hole and the third filter hole are larger than the inner diameter of the second filter hole. The first filter chamber is connected to the bottom of the cyclone filter. The first filter plate is cylindrical, and the first filter hole is located on the side of the first filter plate.
[0010] Furthermore, a first rotating shaft is rotatably connected inside the sewage tank. The first rotating shaft is respectively provided with a first spiral plate, a first scraper, and a second scraper that are in contact with the first filter plate, the second filter plate, and the third filter plate. The second filter hole and the third filter hole are respectively provided with a first recovery tank and a second recovery tank.
[0011] Furthermore, the first and second scrapers are arc-shaped, with the concave parts of their arcs corresponding to the first and second recycling tanks.
[0012] Furthermore, both the first and second recycling tanks are provided with a second rotating shaft, and the second rotating shaft is provided with a second spiral plate that contacts the first and second recycling tanks.
[0013] Furthermore, each of the two second rotating shafts is provided with a first gear, and a second gear that meshes with the first gear is rotatably connected inside the sewage tank. The first rotating shaft is slidably disposed on the sewage tank, and two third gears that mesh with the second gear are provided on the first rotating shaft.
[0014] Furthermore, the end of the first rotating shaft is provided with a groove, and the end of the sewage tank is slidably connected with a push block. The upper and lower sides of the push block are in contact with the groove. Guide rods are provided on both sides of the push block. A slider is slidably connected to the sewage tank. The slider is provided with a first horizontal groove and a second horizontal groove that are in contact with the guide rods. An inclined groove is provided between the first horizontal groove and the second horizontal groove. The inclined groove is in contact with the guide rods and drives the first rotating shaft to slide inside the sewage tank.
[0015] Furthermore, the sewage tank is rotatably connected to a first eccentric wheel and a second eccentric wheel that are in contact with the slider. A fourth gear and a fifth gear are provided on one side of the first eccentric wheel and the second eccentric wheel. A sixth gear that meshes with the fourth gear and the fifth gear is rotatably connected to the sewage tank. An external hexagonal block is provided on one side of the sixth gear.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] 1. When irrigation is needed, raw water is introduced into the cyclone filter through the inlet pipe. Through the guidance of the cyclone filter, centrifugal force and gravity are used to separate large particles of heavy impurities in the raw water, thereby intercepting large particles of heavy impurities in the raw water (sand, stone chips, and silt particles in river water, with a particle size of "≥75μm", such as quartz sand, river sand, and fine stones). It is suitable for high-silt raw water scenarios such as field ditch water and raw water, and achieves preliminary filtration of large particles of impurities in the raw water. This protects the subsequent disc filter and fertilizer unit from wear and blockage, ensures the stability of the fertilizer equipment after long-term operation, improves the service life of the fertilizer equipment, ensures that fertilizer is evenly delivered to the crop roots, improves the fertilization effect, avoids fertilizer waste, and achieves the dual goals of water and fertilizer conservation.
[0018] 2. The cyclone filter achieves solid-liquid separation by relying on the fluid's own gravity, pressure difference, and kinetic energy, without the need for external power drive, further reducing the space required for installation and the cost of manufacturing the filtration fertilization device;
[0019] 3. Raw water filtered by the cyclone filter enters the disc filter through the water supply pipe. The raw water enters from the outer edge and flows to the inner edge through the intersecting grooves between the discs. Suspended particles in the water are intercepted at the intersection of the disc surfaces and the channels, while purified water flows out from the central collection chamber. This process intercepts small particulate impurities in the raw water (fine suspended particles of 20-200μm in river water, such as fine silt, humus particles, algae fragments, plant debris, tiny clay particles, organic flocs, etc.), making it suitable for high-silt raw water scenarios such as field ditch water and raw water. It achieves fine filtration of large particulate impurities in the raw water, thus protecting the subsequent fertilization unit from wear and blockage, ensuring the stability of the fertilization equipment after long-term operation, extending the service life of the fertilization equipment, ensuring even delivery of fertilizer to the crop roots, improving fertilization efficiency, avoiding fertilizer waste, and achieving the dual goals of water and fertilizer conservation. Simultaneously, the cyclone filter relies on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation, requiring no external power drive, further reducing the space required for installation and the manufacturing cost of the filtration fertilization device.
[0020] 4. Both cyclone filters (centrifugal) and disc filters (stacked) rely on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation. They require no external power drive and are individually adaptable to different impurity scenarios, meeting the core design requirements of non-powered devices: "energy saving, low maintenance, and adaptability to field scenarios without power supply."
[0021] 5. Simultaneously, the raw water after passing through the cyclone filter enters the inlet of the medicine tank through the connecting pipe, and mixes with the fertilizer added through the fertilizer inlet of the medicine tank to form a fertilizer mixture, which is convenient for subsequent entry into the water supply pipeline. Then, the raw water after double filtration flows out through the disc filter, passes through the irrigation pipeline, and enters the proportioning pump. The raw water flows through the contraction-type Venturi tube of the proportioning pump, causing a sudden increase in flow velocity and creating a negative pressure zone in the tube. The negative pressure further increases the flow rate of the raw water, and at the same time, the suction draws the fertilizer mixture out of the medicine tank and enters the dosing pipeline through the fertilizer outlet at the bottom of the medicine tank. Then it enters the proportioning pump, which adjusts the mixing ratio of fertilizer mixture and raw water, thereby improving the effect of field irrigation. At the same time, no additional power is needed to pump out the fertilizer mixture, further reducing the space required for installation and the manufacturing cost of the filtration fertilization device. Finally, the fertilizer mixture, which is further mixed with the raw water, is output by the proportioning pump and flows back to the irrigation pipeline, through which it is transported to the appropriate location to realize the irrigation of the field.

[0033] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.
[0034] This invention provides a filter-fertilizer application device without an additional power source, such as... Figure 1 and Figure 2As shown, the system includes a base plate 1 and a medicine tank 2 mounted on the base plate 1. The base plate 1 is equipped with a cyclone filter 3 and a disc filter 4. It also includes an inlet pipe 5 connected to the inlet of the cyclone filter 3, a water supply pipe 6 connected to the outlet of the cyclone filter 3 and the inlet of the disc filter 4, and an irrigation pipe 7 connected to the outlet of the disc filter 4. The bottom of the medicine tank 2 has a fertilizer outlet 8. A proportioning pump 9 is mounted on the irrigation pipe 7. The top of the medicine tank 2 has a water inlet 10, which is connected to a connecting pipe 11 connected to the water supply pipe 6. The side of the medicine tank 2 has a fertilizer inlet 12, and the fertilizer outlet 8 has a drug delivery pipe 13 connected to the proportioning pump 9. When irrigation is needed, the raw water... The water is introduced into the cyclone filter 3 through the inlet pipe 5. Through the guidance of the cyclone filter 3, centrifugal force and gravity are used to separate large particles of heavy impurities in the raw water, thereby intercepting large particles of heavy impurities (sand, stone chips, and silt particles in river water, typically with a particle size ≥75μm, such as quartz sand, river sand, and fine gravel). This is suitable for high-silt raw water scenarios such as field ditch water and raw water, achieving preliminary filtration of large particles of impurities in the raw water. This protects the subsequent disc filter 4 and fertilizer unit from wear and blockage, ensuring the stability of the fertilizer application equipment after long-term operation, extending the service life of the fertilizer application equipment, ensuring uniform delivery of fertilizer to the crop roots, improving fertilization efficiency, avoiding fertilizer waste, and achieving the dual goals of water and fertilizer conservation. Simultaneously, the cyclone filter 3... Solid-liquid separation is achieved through the fluid's own gravity, pressure difference, and kinetic energy, requiring no external power drive, further reducing the space required for installation and the manufacturing cost of the filtration and fertilization device. The raw water, filtered by the cyclone filter 3, enters the disc filter 4 through the water supply pipe 6. The raw water enters from the outer edge and flows to the inner edge through the intersecting grooves between the discs. Suspended particles in the water are intercepted at the intersection of the disc surfaces and the channels, while purified water flows out from the central collection chamber. This process effectively intercepts small particulate impurities in the raw water (fine suspended particles of 20-200μm in river water, such as fine silt, humus particles, algae fragments, plant debris, tiny clay particles, organic flocs, etc.), adapting to high-silt raw water scenarios such as field ditch water and raw water, achieving fine filtration of large particulate impurities in the raw water. The cyclone filter protects the subsequent fertilization unit from wear and blockage, ensuring the stability of the fertilization equipment after long-term operation, extending the service life of the fertilization equipment, ensuring that fertilizer is evenly delivered to the crop roots, improving the fertilization effect, avoiding fertilizer waste, and achieving the dual goals of water and fertilizer conservation. At the same time, the cyclone filter 3 relies on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation without external power drive, further reducing the space required for installation and the cost of manufacturing the filtration fertilization device. Both the cyclone filter 3 (centrifugal) and the disc filter 4 (stacked) rely on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation without external power drive, and are individually adaptable to different impurity scenarios, meeting the core design requirements of "energy saving, low maintenance, and adaptability to field scenarios without power supply" for non-powered devices.
[0035] Meanwhile, the raw water after passing through the cyclone filter 3 enters the inlet 10 of the medicine tank 2 through the connecting pipe 11, and mixes with the fertilizer added through the fertilizer inlet 12 of the medicine tank 2 to form a fertilizer mixture, which is convenient for subsequent entry into the water supply pipe 6; then, the raw water after double filtration flows out through the disc filter 4, and enters the proportioning pump 9 through the irrigation pipe 7, so that the raw water flows through the contraction-type venturi tube of the proportioning pump 9, causing the flow velocity to increase sharply and forming a negative pressure zone in the tube. The negative pressure will further increase the flow rate of the raw water, and at the same time, the suction will increase. The fertilizer mixture in tank 2 is drawn out and enters the dosing pipe 13 through the fertilizer outlet 8 at the bottom of tank 2. Then it enters the proportioning pump 9, which adjusts the mixing ratio of fertilizer mixture and raw water to improve the irrigation effect. At the same time, no additional power is needed to pump the fertilizer mixture out, which further reduces the space required for installation and the cost of manufacturing the filtration fertilization device. Finally, the fertilizer mixture, which is further mixed with raw water, is output by the proportioning pump 9 and flows back to the irrigation pipe 7, through which it is transported to the corresponding location to realize the irrigation of the field.
[0036] Preferred, such as Figure 1 and Figure 2 As shown, the water supply pipe 6, the drug delivery pipe 13, and the connecting pipe 11 are respectively equipped with a first valve 14, a second valve 15, and a third valve 16. The drug delivery pipe 13 is equipped with a drain pipe 17, and the drain pipe 17 is equipped with a fourth valve 18. When it is necessary to mix fertilizer and raw water, first valve 14, second valve 15, and fourth valve 18 are closed, and third valve 16 is opened, so that raw water enters directly into the medicine tank 2 through the water supply pipe 6 and the connecting channel, so that fertilizer and raw water are mixed.
[0037] During normal irrigation of the fields, the first valve 14 and the second valve 15 are opened, and the third valve 16 and the fourth valve 18 are closed, so that the proportioning pump 9 draws fertilizer mixture and raw water into the irrigation channel to irrigate the fields.
[0038] When it is necessary to flush the medicine tank 2, close the first valve 14, the second valve 15 and the fourth valve 18, and open the third valve 16 to allow raw water to enter the medicine tank 2 to flush the inside of the tank until the water volume inside the tank reaches 3 / 4 of the tank's height. Then, open the fourth valve 18 to discharge the wastewater from the tank.
[0039] Preferred, such as Figure 1 and Figure 2As shown, it also includes a sludge tank 19 connected to the bottom of the cyclone filter 3, and a return pipe 20 connecting the sludge tank 19 and the water supply pipe 6. The sludge tank 19 is equipped with a sludge pipe 21. The sludge tank 19 intercepts the mud and sand separated by the cyclone filter 3, so that the mud and sand are further separated from the water flow. Then, the filtered water flow returns to the water supply pipe 6 through the return pipe 20, which avoids the water flow at the bottom of the cyclone filter 3 from staying for a long time, which would affect the effect of the cyclone filter 3 in separating mud and sand. At the same time, it also prevents the bottom water flow from rising and carrying the lighter mud and sand back to the top. When the mud and sand in the sludge tank 19 accumulate to a certain amount, the valve on the sludge pipe 21 is opened, and the mud and sand are flushed out of the sludge tank 19 by the water flow.
[0040] Preferred, such as Figure 3 and Figure 4 As shown, the sewage tank 19 is equipped with a first filter plate 22, a second filter plate 23, and a third filter plate 24, which divide the tank into a first filter chamber 25, a second filter chamber 26, a third filter chamber 27, and a fourth filter chamber 28, respectively. The return pipe 20 is connected to the second filter chamber 26 and the fourth filter chamber 28, respectively. The first filter plate 22, the second filter plate 23, and the third filter plate 24 are respectively provided with a first filter hole 29, a second filter hole 30, and a third filter hole 31. The inner diameters of the first filter hole 29 and the third filter hole 31 are equal. The inner diameter of the third filter hole 31 is larger than the inner diameter of the second filter hole 30. The first filter chamber 25 is connected to the bottom of the cyclone filter 3. The silt filtered by the cyclone filter 3 enters the first filter chamber 25. The large amount of water contained in the silt directly passes through the first filter hole 29 of the first filter plate 22 and enters the second filter chamber 26. It then flows back to the water supply pipe 6 from the return pipe 20, thereby filtering out a large amount of water from the silt. The first filter plate 22 is cylindrical, and the first filter hole 29 is located on the side of the first filter plate 22 to avoid silt clogging the filter holes and further improve the efficiency and effect of filtration and silt removal.
[0041] Next, the remaining small amount of water and impurities remain on the second filter plate 23. The second filter hole 30 is relatively large, allowing smaller impurities and water to pass through smoothly, while larger impurities cannot pass through the second filter hole 30, thus removing stones from the silt. Finally, the water passes through the third filter hole 31 on the third filter plate 24, filtering out smaller impurities. The remaining water flows through the third filter hole 31 and returns to the water supply pipe 6 through the return pipe 20, thus filtering out the remaining water in the silt. At the same time, through multiple filtration, the silt is further prevented from clogging the filter holes, further improving the efficiency and effect of filtration and silt removal.
[0042] Preferred, such as Figures 3-5As shown, a first rotating shaft 32 is rotatably connected inside the sewage tank 19. The first rotating shaft 32 is respectively equipped with a first spiral plate 33, a first scraper 34, and a second scraper 35 that contact the first filter plate 22, the second filter plate 23, and the third filter plate 24. A first recovery tank 36 and a second recovery tank 37 are respectively installed on the second filter holes 30 and the third filter holes 31. The force generated by the impact of mud and water on the spiral plate is transmitted through the first spiral plate 33 to the first rotating shaft 32, thereby driving the first rotating shaft 32. Shaft 32 rotates within the sewage tank 19, causing the first spiral plate 33, the first scraper 34, and the second scraper 35 to contact the first filter plate 22, the second filter plate 23, and the third filter plate 24, respectively. This movement causes the sediment on the first filter plate 22, the second filter plate 23, and the third filter plate 24 to move, preventing sediment from remaining on these plates for extended periods and clogging the first filter holes 29, the second filter holes 30, and the third filter holes 31. This, in turn, improves the efficiency of sediment removal through filtration. Finally, the rotation of the first spiral plate 33 continuously drives the sediment in the first filter chamber 25 downwards, while preventing the water flow from moving directly downwards. This allows most of the water to be discharged through the filter holes on the side, further improving the efficiency and effectiveness of sediment removal. Simultaneously, the continuous movement of the second scraper 35 and the third scraper causes the sediment to gradually fall into the corresponding first recovery tank 36 and second recovery tank 37. When the sediment in the first recovery tank 36 and second recovery tank 37 accumulates to a certain amount, the valve on the sewage pipe 21 is opened, and the sediment in the first recovery tank 36 and second recovery tank 37 is discharged into the sewage tank 19 through the sewage pipe 21, thereby achieving the removal of sediment from the raw water. At the same time, personnel can discharge the sediment in the sewage tank 19 without periodically disassembling it, further reducing the labor intensity required for irrigation. Furthermore, no additional power equipment is needed to drive the first rotating shaft 32 to rotate, further reducing the space required for installation and the manufacturing cost of the filtration and fertilization equipment.
[0043] Preferred, such as Figures 3-5 As shown, the first scraper 34 and the second scraper 35 are arc-shaped, and their concave parts correspond to the first recycling tank 36 and the second recycling tank 37. When the arc-shaped first scraper 34 and the second scraper 35 come into contact with the impurities, the resulting component force causes them to converge into the concave parts of the arc-shaped first scraper 34 and the second scraper 35, making it easier for them to fall into the first recycling tank 36 and the second recycling tank 37, thereby improving the effect of filtering and removing mud and sand.
[0044] Preferred, such as Figure 3 and Figure 4As shown, both the first recycling tank 36 and the second recycling tank 37 are equipped with a second rotating shaft 38. The second rotating shaft 38 is equipped with a second spiral plate 39 that contacts the first recycling tank 36 and the second recycling tank 37. When it is necessary to discharge sludge from the first recycling tank 36 and the second recycling tank 37, the second rotating shaft 38 is rotated on the first recycling tank 36 and the second recycling tank 37 respectively, which drives the corresponding second spiral plate 39 to contact the sludge in the first recycling tank 36 and the second recycling tank 37. The resulting force pushes the sludge spiral downward until the sludge is discharged from the sewage pipe 21 into the sewage tank 19, thus avoiding sludge residue in the first recycling tank 36 and the second recycling tank 37 and improving the effect of removing sludge from the first recycling tank 36 and the second recycling tank 37.
[0045] Preferred, such as Figures 3-5 As shown, each of the two second rotating shafts 38 is equipped with a first gear 40. A second gear 41, meshing with the first gear 40, is rotatably connected inside the sewage tank 19. The first rotating shaft 32 is slidably mounted on the sewage tank 19. Two third gears 42 on the first rotating shaft 32 mesh with the second gear 41. During normal irrigation, the third gears 42 on the first rotating shaft 32 do not mesh with the corresponding second gears 41, thus not driving the second spiral plates 39 on the first and second recovery tanks 36 and 37 to rotate. This reduces the resistance generated by rotation, ensuring the smooth rotation of the first spiral plate 33, the first scraper 34, and the second scraper 35, and ensuring the water in the sediment flows back to the... Water supply pipe 6 irrigates the fields; when silt needs to be discharged, the first rotating shaft 32 is slid, causing the third gear 42 to mesh with the second gear 41. When water flows into the sewage tank 19, the power generated by the contact between the first spiral plate 33 and the water flow drives the first rotating shaft 32 to rotate. This torque is transmitted through the first gear 40, the second gear 41, and the third gear 42, which drives the second rotating shaft 38 to rotate, and drives the second spiral plate 39 to rotate, discharging silt from the first recycling tank 36 and the second recycling tank 37. This prevents silt from remaining in the first recycling tank 36 and the second recycling tank 37, improving the efficiency of silt removal from the first recycling tank 36 and the second recycling tank 37.
[0046] Preferred, such as Figure 4 and Figure 6As shown, the first rotating shaft 32 has a groove 43 at its end, and a push block 44 is slidably connected to the end of the sewage tank 19. The upper and lower sides of the push block 44 are in contact with the groove 43. Guide rods 45 are provided on both sides of the push block 44. A slider 46 is slidably connected to the sewage tank 19. The slider 46 has a first horizontal groove 47 and a second horizontal groove 48 that are in contact with the guide rods 45. An inclined groove 49 is provided between the first horizontal groove 47 and the second horizontal groove 48. The inclined groove 49 is in contact with the guide rods 45 and drives the first rotating shaft. The first rotating shaft 32 slides within the sewage tank 19, thereby adjusting its position and changing the connection between the first rotating shaft 32 and the second rotating shaft 38 to meet the needs of removing silt under different conditions. Furthermore, after adjustment, the first horizontal groove 47 and the second horizontal groove 48 contact the guide rod 45 respectively, and the resulting resistance restricts the guide rod 45 from moving up and down. In conjunction with the upper and lower sides of the push block 44 contacting the groove 43, the rotating shaft is restricted from sliding on the sewage tank 19, ensuring the stability of the overall structure and improving the effect of removing and filtering silt.
[0047] Preferred, such as Figure 4 and Figure 6 As shown, a first eccentric wheel 50 and a second eccentric wheel 51, which are in contact with the slider 46, are rotatably connected to the sewage tank 19. A fourth gear 52 and a fifth gear 53 are provided on one side of the first eccentric wheel 50 and the second eccentric wheel 51. A sixth gear 54, which meshes with the fourth gear 52 and the fifth gear 53, is rotatably connected to the sewage tank 19. An external hexagonal block 55 is provided on one side of the sixth gear 54. When it is necessary to change the position of the slider 46, the sixth gear 54 is driven by rotating the handle shaft and the external hexagonal block 55. The rotation of the sewage tank 19 generates torque that is transmitted to the first eccentric wheel 50 and the second eccentric wheel 51 through the fourth gear 52 and the fifth gear 53, causing the first eccentric wheel 50 and the second eccentric wheel 51 to rotate in opposite directions. The first eccentric wheel 50 and the second eccentric wheel 51 contact the push block 44 through their sides, and the resulting force causes the slider 46 to slide on the sewage tank 19, thereby changing the position of the first rotating shaft 32 and changing the connection state between the first rotating shaft 32 and the second rotating shaft 38 to meet the needs of removing mud and sand under different conditions.
[0048] Example 1
[0049] This invention provides a filter-fertilizer application device without an additional power source, such as... Figure 1 and Figure 2As shown, when irrigation is needed, raw water is introduced into the cyclone filter 3 through the inlet pipe 5. The cyclone filter 3 guides the flow, using centrifugal force and gravity to separate large particles of heavy impurities from the raw water. This intercepts large particles of heavy impurities (sand, stone chips, and silt particles in river water, typically ≥75μm in diameter, such as quartz sand, river sand, and fine gravel). This method is suitable for high-siltation raw water scenarios such as field ditch water and raw water, achieving preliminary filtration of large particles of impurities in the raw water. This protects the subsequent disc filter 4 and fertilizer unit from wear and blockage, ensuring the fertilizer equipment can operate for extended periods. The stability after operation is improved, extending the service life of the fertilization equipment, ensuring uniform delivery of fertilizer to crop roots, enhancing fertilization effectiveness, avoiding fertilizer waste, and achieving the dual goals of water and fertilizer conservation. Simultaneously, the cyclone filter 3 relies on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation, requiring no external power drive, further reducing the space required for installation and the manufacturing cost of the filtration fertilization device. The raw water filtered by the cyclone filter 3 enters the disc filter 4 through the water supply pipe 6, allowing the raw water to enter from the outer edge, flow through the cross grooves between the discs to the inner edge, while the suspended solids in the water... Floating particles are intercepted at the intersection of the stacked plates and the channel, while purified water flows out from the central collection chamber. This process intercepts small particulate impurities in the raw water (fine suspended particles of 20-200μm in river water, such as fine silt, humus particles, algae fragments, plant debris, tiny clay particles, organic flocs, etc.), adapting to high-silt raw water scenarios such as field ditch water and raw water. It achieves fine filtration of large particulate impurities in the raw water, thereby protecting the subsequent fertilization unit from wear and blockage, ensuring the stability of the fertilization equipment after long-term operation, extending the service life of the fertilization equipment, and ensuring uniform fertilizer delivery. The cyclone filter 3, applied to the root zone of crops, enhances fertilization efficiency, avoids fertilizer waste, and achieves the dual goals of water and fertilizer conservation. Simultaneously, the cyclone filter 3 utilizes the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation, requiring no external power drive, further reducing the space required for installation and the manufacturing cost of the filtration fertilization device. Both the cyclone filter 3 (centrifugal) and the disc filter 4 (stacked) rely on the fluid's own gravity, pressure difference, and kinetic energy to achieve solid-liquid separation, requiring no external power drive. They are individually adaptable to different impurity scenarios, meeting the core design requirements of powerless devices: "energy saving, low maintenance, and adaptability to field scenarios without power supply."
[0050] Meanwhile, the raw water after passing through the cyclone filter 3 enters the inlet 10 of the medicine tank 2 through the connecting pipe 11, and mixes with the fertilizer added through the fertilizer inlet 12 of the medicine tank 2 to form a fertilizer mixture, which is convenient for subsequent entry into the water supply pipe 6; then, the raw water after double filtration flows out through the disc filter 4, and enters the proportioning pump 9 through the irrigation pipe 7, so that the raw water flows through the contraction-type venturi tube of the proportioning pump 9, causing the flow velocity to increase sharply and forming a negative pressure zone in the tube. The negative pressure will further increase the flow rate of the raw water, and at the same time, the suction will increase. The fertilizer mixture in tank 2 is drawn out and enters the dosing pipe 13 through the fertilizer outlet 8 at the bottom of tank 2. Then it enters the proportioning pump 9, which adjusts the mixing ratio of fertilizer mixture and raw water to improve the irrigation effect. At the same time, no additional power is needed to pump the fertilizer mixture out, which further reduces the space required for installation and the cost of manufacturing the filtration fertilization device. Finally, the fertilizer mixture, which is further mixed with raw water, is output by the proportioning pump 9 and flows back to the irrigation pipe 7, through which it is transported to the corresponding location to realize the irrigation of the field.
[0051] Example 2
[0052] Based on Example 1, such as Figure 1 and Figure 2 As shown, when it is necessary to mix fertilizer and raw water, first close the first valve 14, the second valve 15 and the fourth valve 18, and open the third valve 16 so that the raw water can directly enter the medicine tank 2 through the water supply pipe 6 and the connecting channel, so that the fertilizer and raw water can be mixed.
[0053] During normal irrigation of the fields, the first valve 14 and the second valve 15 are opened, and the third valve 16 and the fourth valve 18 are closed, so that the proportioning pump 9 draws fertilizer mixture and raw water into the irrigation channel to irrigate the fields.
[0054] When it is necessary to flush the medicine tank 2, close the first valve 14, the second valve 15 and the fourth valve 18, and open the third valve 16 to allow raw water to enter the medicine tank 2 to flush the inside of the tank until the water volume inside the tank reaches 3 / 4 of the tank's height. Then, open the fourth valve 18 to discharge the wastewater from the tank.
[0055] In addition, the sludge separated by the cyclone filter 3 is intercepted by the sewage tank 19, which further separates the sludge from the water flow. Then, the filtered water flows back to the water supply pipe 6 through the return pipe 20, which prevents the water flow at the bottom of the cyclone filter 3 from staying for a long time and affecting the effect of the cyclone filter 3 in separating sludge. At the same time, it also prevents the bottom water flow from rising and carrying the lighter sludge back to the top. When the sludge in the sewage tank 19 accumulates to a certain amount, the valve on the sewage pipe 21 is opened, and the sludge is flushed out of the sewage tank 19 by the water flow.
[0056] Example 3
[0057] Based on Example 2, such as Figures 3-6 As shown, after being filtered by the cyclone filter 3, the silt enters the sewage tank 19 and first enters the first filter chamber 25. The large amount of water contained in the silt directly passes through the first filter hole 29 of the first filter plate 22 and enters the second filter chamber 26. It then flows back to the water supply pipe 6 through the return pipe 20, thereby filtering out a large amount of water from the silt. In addition, since the first filter plate 22 is cylindrical and the first filter hole 29 is located on the side of the first filter plate 22, the silt is prevented from clogging the filter hole, further improving the efficiency and effect of filtration and silt removal.
[0058] Next, the remaining small amount of water and impurities remain on the second filter plate 23. The second filter hole 30 is relatively large, allowing smaller impurities and water to pass through the second filter hole 30 smoothly, while larger impurities cannot pass through the second filter hole 30, thereby removing stones from the silt. Finally, the water passes through the third filter hole 31 on the third filter plate 24, filtering out smaller impurities. The remaining water flows through the third filter hole 31 and returns to the water supply pipe 6 through the return pipe 20, thereby filtering out the remaining water in the silt. At the same time, through multiple filtration, the silt is further prevented from clogging the filter holes, further improving the efficiency and effect of filtration and silt removal.
[0059] Simultaneously, after the silt and water flow enter the first filter chamber 25, the impact of the silt and water flow on the spiral plate generates a component force that is transmitted through the first spiral plate 33 to the first rotating shaft 32. This causes the first rotating shaft 32 to rotate within the sewage tank 19, making the first spiral plate 33, the first scraper 34, and the second scraper 35 contact the first filter plate 22, the second filter plate 23, and the third filter plate 24, respectively. This causes the silt on the first filter plate 22, the second filter plate 23, and the third filter plate 24 to move on them, preventing the silt from remaining stationary for extended periods. The sediment remains on the first filter plate 22, the second filter plate 23, and the third filter plate 24, clogging the first filter hole 29, the second filter hole 30, and the third filter hole 31, thereby improving the efficiency and effect of filtration and sediment removal. Finally, the rotation of the first spiral plate 33 continuously drives the sediment in the first filter chamber 25 downward, while preventing the water flow from moving directly downward, so that most of the water flow is discharged from the filter holes provided on the side, further improving the efficiency and effect of filtration and sediment removal. At the same time, the continuous movement of the second scraper 35 and the third scraper... This process allows the sediment to gradually fall into the corresponding first and second recovery tanks 36 and 37. When the sediment in the first and second recovery tanks 36 and 37 accumulates to a certain amount, the valve on the sewage pipe 21 is opened, and the sediment in the first and second recovery tanks 36 and 37 is discharged into the sewage tank 19 through the sewage pipe 21 by the water flow, thereby removing sediment from the raw water. At the same time, personnel can discharge the sediment in the sewage tank 19 without periodically disassembling it, further reducing the labor intensity required for irrigation. In addition, no additional power equipment is needed to drive the first rotating shaft 32 to rotate, further reducing the space required for installation and the cost of manufacturing the filtration and fertilization equipment. Furthermore, the first scraper 34 and the second scraper 35 are arc-shaped. The component force generated by the arc-shaped first scraper 34 and the second scraper 35 in contact with the impurities causes them to converge into the concave part of the arc of the first scraper 34 and the second scraper 35, which facilitates subsequent falling into the first and second recovery tanks 36 and 37, thereby improving the filtration and removal effect of sediment.
[0060] Example 4
[0061] Based on Example 1, such as Figures 3-6 As shown, during normal irrigation, the guide rod 45 is located in the first transverse groove 47. The first transverse groove 47 contacts the guide rod 45, and the resistance generated restricts the guide rod 45 from moving up and down. In conjunction with the upper and lower sides of the push block 44 contacting the groove 43, the rotating shaft is restricted from sliding on the sewage tank 19, ensuring the stability of the overall structure and improving the effect of removing and filtering mud and sand. At this time, the third gear 42 on the first rotating shaft 32 does not mesh with the corresponding second gear 41, and does not drive the second spiral plate 39 on the first recovery tank 36 and the second recovery tank 37 to rotate, reducing the resistance generated by rotation and ensuring that the first spiral plate 33, the first scraper 34 and the second scraper 35 rotate smoothly, ensuring that the water in the mud and sand flows back to the water supply pipe 6, realizing the irrigation of the field.
[0062] When it is necessary to discharge the sludge from the first recycling tank 36 and the second recycling tank 37, the sixth gear 54 is driven to rotate on the sewage tank 19 by rotating the handle shaft hexagonal connector 55. The generated torque is transmitted to the first eccentric wheel 50 and the second eccentric wheel 51 through the fourth gear 52 and the fifth gear 53, causing the first eccentric wheel 50 and the second eccentric wheel 51 to rotate in opposite directions. The sides of the first eccentric wheel 50 and the second eccentric wheel 51 contact the push block 44, and the resulting force causes the slider 46 to slide on the sewage tank 19, so that the inclined groove 49 contacts the guide rod 45. The resulting force causes the first rotating shaft 32 to slide inside the sewage tank 19, thereby realizing the adjustment of the position of the first rotating shaft 32. The third gear 42 on the first rotating shaft 32 meshes with the corresponding second gear 41, changing the connection state between the first rotating shaft 32 and the second rotating shaft 38. Water is then introduced into the sewage tank 19. The power generated by the first spiral plate 33 contacting the water drives the first rotating shaft 32 to rotate. Torque is then transmitted through the first gear 40, the second gear 41, and the third gear 42, which in turn drives the second rotating shaft 38 to rotate. This drives the second spiral plate 39 to rotate, discharging silt from the first recycling tank 36 and the second recycling tank 37. This prevents silt from remaining in the first recycling tank 36 and the second recycling tank 37, improving the efficiency of removing silt from the first recycling tank 36 and the second recycling tank 37.
