Description

Technical Field

[0001] This invention relates to the field of fertilization technology for ratooning rice, and specifically to a high-efficiency spraying device for fertilizing ratooning rice. Background Technology

[0002] Ratoon rice is a planting model with significant advantages. It utilizes the rice stubble after harvesting, and through proper cultivation, encourages the axillary buds to sprout into panicles, achieving "one plant, two harvests," greatly improving land utilization and grain yield. In many areas of southern my country, ratoon rice is widely planted, becoming one of the important ways to ensure food security.

[0003] Fertilization is a crucial step in the cultivation of ratooning rice. Proper fertilization provides sufficient nutrients for the growth of ratooning rice, promoting tillering, heading, and grain filling, thereby increasing yield and quality. For large-scale ratooning rice fields, efficient and uniform fertilization is an important guarantee for achieving high-quality and high-yield crops.

[0004] Currently, there are various types of equipment available on the market for fertilizing and spraying large areas of paddy fields. Among them, some tractor-tethered spraying devices, while improving efficiency to some extent, can easily cause soil compaction when tractors travel in paddy fields, affecting the growth and development of rice roots.

[0005] Another common type is the suspended spraying device, which is usually installed on drones or helicopters for aerial spraying. Although aerial spraying has the advantages of speed and wide coverage, it has problems such as low spraying accuracy, fertilizer is easily affected by factors such as wind, resulting in over- or under-fertilization in some areas, and the equipment is also more expensive and difficult to maintain.

Detailed Implementation

[0025] Next, we will combine the appendix Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0026] A high-efficiency spraying device for fertilizing regenerated rice, such as Figure 1As shown, the device includes two symmetrically arranged mobile vehicles 1. Each mobile vehicle 1 has a drive mechanism inside, which is used to drive the mobile vehicle 1 to move. This technology is existing technology and will not be elaborated on here. A mixing tank 2 is fixedly installed at the front end of the mobile vehicle 1 on the right side. The mixing tank 2 has a feed inlet at the top and a cover plate on the feed inlet. The feed inlet is used to feed compound fertilizer. A connecting pump 3 is also fixedly installed on the bottom side of the mixing tank 2. One end of the connecting pump 3 is connected to the discharge port at the bottom of the mixing tank 2, and the other end is connected to a metal pipe 4. The other end of the metal pipe 4 is connected to a flexible hose 5. Multiple atomizing electronically controlled valves 6 are evenly arranged at the lower end of the flexible hose 5. Furthermore, in order to make the metal pipe 4 firmly fixed, the metal pipe 4 is fixedly connected to the mixing tank 2 on the right side through a fixing plate 6. The atomizing electronically controlled valves 6 are opened and closed electronically. This technology is existing technology and will not be elaborated on here.

[0027] In use, the two mobile carts 1 are positioned on either side of the paddy field requiring fertilization. Compound fertilizer and water are fed into the mixing tanks 2 on either side through the inlet. The compound fertilizer and water dissolve, and spraying the dissolved compound fertilizer facilitates rapid nutrient absorption by the rice. The solution of compound fertilizer penetrates the soil more quickly and is utilized by the roots than solid fertilizer, providing sufficient nutrients for the growth of the ratooning rice. The hose 5 is then connected to the metal pipe 4, and then to the mobile cart 1 on the left. The connecting pump 3 is then activated, and the dissolved compound fertilizer enters the hose 5 from the outlet at the bottom of the mixing tank 2. The atomizing valve 6 is then opened, and the nutrient solution inside is atomized and sprayed. It should be noted that when the atomizing valve 6 is opened, the drive mechanism propels the two mobile carts 1 forward. The speed of the forward movement of the mobile carts 1 is adjusted according to the different spraying levels to match the spraying speed. This technology is existing and will not be elaborated upon further.

[0028] like Figure 2 As shown above, the compound fertilizer needs to be dissolved inside the mixing tank 2. To make the dissolution more complete, a support plate 7 is also provided inside the mixing tank 2. The feed pipe connected to one end of the pump 3 is connected to the mixing tank 2 through the support plate 7. A stirring rod 8 is provided inside the mixing tank 2. The stirring rod 8 passes through the support plate 7 and is connected to the support plate 7 through a bearing. A drive motor 9 is also provided between the support plate 7 and the bottom of the mixing tank 2. The output shaft of the drive motor 9 is fixedly connected to the stirring rod 8. That is, starting the drive motor 9 will cause the stirring rod 8 to rotate, thereby fully dissolving the compound fertilizer and water inside.

[0029] As is common sense, when the hose 5 is stretched, it will sag in the middle due to the weight of the hose. Based on this, a connecting air tube 10 is provided on one side of the hose 5. The connecting air tube 10 is made of a soft material, such as rubber. Multiple connecting tubes 11 are evenly provided between the connecting air tube 10 and the hose 5. It should be noted that the connecting tubes 11 are connected to the connecting air tube 10, but not to the hose 5. This also increases the structural strength of the connecting cylinder 10 and the hose 5.

[0030] An air float 12 is connected to the middle of the connecting pipe 11. At this time, the connecting air pipe 10 needs to be inflated to allow the air float 12 to float, preventing the hose 5 and connecting air pipe 10 from sagging due to gravity. Additionally, an air storage tank 13 is provided on the left-side mobile vehicle 1. The air storage tank 13 is used to inflate the air float 12, allowing it to expand and preventing the hose 5 and connecting air pipe 10 from sagging due to gravity.

[0031] like Figures 4-5 As shown above, when needed, the hose 5 is first connected to the metal pipe 4, and then connected to the mobile vehicle 1 on the left. However, after use, the hose 5 needs to be stored. When storing the hose 5, the connecting air pipe 10 also needs to be stored. That is, a collection box 14 is provided at the front end of the air storage box 13. The collection box 14 is fixedly connected to the mobile vehicle 1 on the left. A rotating storage component 15 is provided between the air storage box 13 and the collection box 14. The rotating storage component 15 is used to store the hose 5 and the connecting air pipe 10 after use.

[0032] Specifically, the rotating storage component 15 includes two storage cylinders 16 arranged vertically. The upper storage cylinder 16 is hollow, while the lower storage cylinder 16 is solid. A gap is provided between the two storage cylinders 16. This gap is reserved for the atomizing electronic control valve 6, the air float ball 12, and the connecting pipe 11. That is, when the rotating storage component 15 is used for storage, the atomizing electronic control valve 6, the air float ball 12, and the connecting pipe 11 are in the gap between the two layers, thus avoiding damage to the atomizing electronic control valve 6, the air float ball 12, and the connecting pipe 11.

[0033] Protective plates 17 are provided on both sides of the storage cylinder 16. The storage cylinder 16 needs to be rotated, as connecting plates 18 are provided on both sides of the storage cylinder 16, located on the sides of the protective plates 17. Fixing plates 19 are provided on both sides of the connecting plates 18, and the fixing plates 19 are fixedly connected to the mobile vehicle 1. Rotating the connecting plates 18 causes the storage cylinders 16 on both sides to rotate, thereby storing the hose 5 and the connecting air pipe 10. Of course, one end of the hose 5 and the connecting air pipe 10 is connected to the upper storage cylinder 16; that is, during rotation, the hose 5 and the connecting air pipe 10 can be stored. It should be noted that a partition is provided in the middle of the storage cylinder 16, and the hose 5 and the connecting air pipe 10 are located on opposite sides of the partition, respectively, where they connect to the storage cylinder 16.

[0034] like Figures 4-5 As shown above, the air storage tank 13 is used to inflate the connecting air pipe 10. Specifically, a reciprocating screw 21 is vertically installed inside the air storage tank 13. Both the upper and lower ends of the reciprocating screw 21 are connected to the upper and lower ends of the air storage tank 13 via bearings. A pressing plate 22 is threadedly connected to the middle of the reciprocating screw 21. Rotation of the reciprocating screw 21 causes the pressing plate 22 to rise or fall, thereby inflating the air float 12. It should be noted that a normally open valve 23 is also provided on the side of the air storage tank 13; the lowest point of the pressing plate 22 is higher than the height of the valve 23.

[0035] A connecting conduit 24 is also provided at the upper end of the gas storage pipe 13. The connecting conduit 24 is connected to the upper end of the gas storage box 13 and is connected to the connecting gas pipe 10.

[0036] like Figures 4-6 As shown, on the one hand, it is necessary to accommodate the connecting air pipe 10, and on the other hand, it is necessary to inflate the connecting cylinder 10. Based on the above reasons, this application achieves this through the following measures: a rotating shaft 25 is rotatably connected to the upper end of the fixing plate 19 near the air storage box 13. One end of the rotating shaft 25 is fixedly connected to the connecting plate 18. The rotating shaft 25 is hollow and has multiple notches 26 evenly provided at the front end of the rotating shaft 25. One end of the connecting conduit 24 is connected to the inside of the air storage box 13, and the other end passes through the upper end of the fixing plate 19 and is connected to the notch 26. A connecting pipe 27 is provided inside the connecting plate 18. The connecting pipe 27 is connected to the air cavity inside the storage cylinder 16 on the right side, and the other end is connected to the cavity inside the rotating shaft 25.

[0037] As mentioned above, after use, the hose 5 needs to be stored. When storing the hose 5, since there is still unsprayed compound fertilizer solution inside the cavity of the left-side storage cylinder 16, it is necessary to collect the compound fertilizer solution in the left-side storage cylinder 16. As mentioned earlier, a collection box 14 is provided at the front end of the gas storage box 13; that is, a rotating shaft 25 is also rotatably connected to the upper end of the fixing plate 19 near the collection box 14. One end of the rotating shaft 25 is fixedly connected to the connecting plate 18, and the rotating shaft 25 is hollow. Furthermore, multiple notches 26 are evenly provided at the front end of the rotating shaft 25, and a connecting water pipe 28 is provided on one side of the collection box 14. One end of the connecting water pipe 28 is connected to the inside of the collection box 14, and the other end passes through the upper end of the fixing plate 19 and is connected to the notch 26. A U-shaped tube 29 is provided inside the connecting plate 18. The short part of the U-shaped tube 29 is located inside the left side of the storage cylinder 16, and the long end is connected to the cavity inside the rotating shaft 25. That is, the compound fertilizer solution at the upper end of the storage cylinder 16 can be discharged from the inside and collected into the collection box 14 by means of the siphon principle.

[0038] This application utilizes the siphon principle to discharge the compound fertilizer solution located at the upper end of the collection cylinder 16. A rotary motor 30 is installed at the bottom of the collection box 14, and the output shaft of the rotary motor 30 passes through the bottom of the collection box 14 and is connected to the bearing at the bottom of the collection box 14. A reciprocating screw 21 is also installed inside the collection box 14. One end of the reciprocating screw 21 is fixedly connected to the output end of the rotary motor 30, and the other end is connected to the top plate of the collection box 14 through a bearing. An adsorption plate 31 is threadedly connected in the middle of the reciprocating screw 21. The connection position of the connecting water pipe 28 is between the adsorption plate 31 and the bottom of the collection box 14. That is, by starting the rotary motor 30, the adsorption plate 31 moves up and down, thereby adsorbing the air inside the connecting water pipe 28 and the U-shaped pipe 29 into the collection box 14. Subsequently, the solution in the collection cylinder 16 will also enter the collection box 14. It should be noted that a drain valve 32 is also provided on the side of the collection box 14, and an air outlet is also provided on the top of the collection box 14.

[0039] like Figures 4-6As described above, the storage cylinder 16 needs to be rotated. This application achieves the rotation of the storage cylinder 16 by rotating the rotating shaft 25. That is, a power source is needed to rotate the rotating shaft 25. The rotating motor 30 is also fixedly provided with a drive wheel at the output end at the bottom of the collection box 14. A driven wheel 33 is also provided on one side of the collection box 14. The drive wheel and the driven wheel 33 are connected by a first belt 34. A support rod 35 is provided in the middle of the driven wheel 33. One end of the support rod 35 is connected to the drive wheel 33 by a bearing. The base plate of the mobile vehicle 1 is fixedly connected, and the upper end is fixedly connected to a bevel gear A36. A helical gear B37 meshes perpendicularly with the side of the bevel gear A36. The helical gear B37 is fixedly connected to the rotating shaft 25 through a connecting rod. That is, by rotating the rotary motor 30, the driving wheel rotates, which in turn drives the driven wheel 33 to rotate, which drives the bevel gear A36 to rotate, which in turn drives the helical gear B37 to rotate, which in turn drives the rotating shaft 25 to rotate, which in turn drives the storage cylinder 16 to rotate. The bevel gear A36 and the helical gear B37 are gear-meshing connected.

[0040] The above method will also drive the right-side rotating shaft 25 to rotate. A rotating rod is also fixedly provided on the outside of the right-side rotating shaft 25. The rotating rod is connected to the gas storage box 13 through a bearing. A first rotating wheel 38 is provided on the rotating rod. A second rotating wheel 39 is provided at the upper end of the first rotating wheel 38. A connecting rod 40 is fixedly provided in the middle of the second rotating wheel 39. The connecting rod 40 passes through the gas storage box 13 and is connected to the gas storage box 13 through a bearing. A helical gear C41 is fixedly connected to the end of the connecting rod 40. A bevel gear D42 is fixedly provided at the upper end of the reciprocating screw 21 inside the gas storage box 13. The helical gear C41 and the bevel gear D42 are meshed. The first rotating wheel 38 is connected to the second rotating wheel 39 through a second belt 50.

[0041] like Figure 3 As shown, one end of the connecting air tube 10 is connected to the upper end of the collecting cylinder 16, and the other end is connected to the flexible tube 5 through the fixing tube 43. A fixing plate 44 is fixed inside the fixing tube 43, and a sliding rod 45 is slidably connected in the middle of the fixing plate 44. A sealing ball 46 is fixed at the front end of the sliding rod 45, and a spring 47 is provided between the sealing ball 46 and the fixing plate 44. The sealing ball 46 is used to seal the opening of the connecting air tube 10 to prevent gas from entering the flexible tube 5 when it is inflated. It should be noted that when the air float 12 is inflated until the connecting air tube is stable, the sealing ball 46 is still in a sealed state. When collecting from the connecting air tube 10, the pressure inside the connecting air tube 10 increases due to the rotation of the collecting cylinder 16, which squeezes the sealing ball 46 and then compresses the spring 47, thereby blowing the dissolved liquid in the flexible tube 5 into the collecting cylinder 15 for collection.

[0042] Since the hose needs to be stored, it must be disconnected from the metal pipe. This prevents gas from blowing the dissolved liquid in the hose 5 into the collection cylinder 15 for collection. A cover plate 20 with a through hole is provided at the front end of the hose 5. A sealing plate 48 is connected to the front end of the cover plate 20 via a torsion spring. Initially, the sealing plate 48 seals the outlet of the hose 5 due to the torsion spring. When the hose 5 is connected to the metal pipe 4, and the pump 3 is operating, the dissolved liquid in the metal pipe will force open the sealing plate 48, allowing the dissolved liquid to enter the hose. When the hose 5 is not connected to the metal pipe 4, the sealed end of the hose allows the dissolved liquid in the hose 5 to be blown into the collection cylinder 15 for collection.

[0043] like Figure 3 As shown above, the hose 5 is connected to the metal pipe 4. To facilitate the connection between the two, a thread is provided at the end of the hose 5. Correspondingly, a rotating part 49 is provided on the metal pipe 4. The front end of the rotating part 49 has an internal threaded groove. The threaded groove is adapted to the thread. That is, by rotating the rotating part 49, the threaded groove is adapted to the thread, and then the front end of the hose 5 is pulled into the front end of the rotating part 49.

[0044] When in use, first move the trolley to both sides of the paddy field to be sprayed, then pull the hose 5 and simultaneously start the rotary motor 30 to flip the storage cylinder 5, increasing the pulling speed. When pulled to the designated position, the air float will be fully inflated. At this point, connect the hose to the metal pipe 4, then turn off the rotary motor 30, start the drive motor 9 and drive mechanism, and open the atomizing electronic control valve. The trolley will then spray along the paddy field. After spraying is complete, turn off the drive motor 9 and drive mechanism and open the atomizing electronic control valve. Then disconnect the end of the hose from the metal pipe, and then start the rotary motor 30. At this point, the adsorption plate 31 and the extrusion plate 22... The process continues upwards, collecting the dissolved liquid in the collection cylinder while simultaneously inflating the air flotation ball 12 and squeezing the sealing ball 46. This compresses the spring 47, allowing the dissolved liquid in the hose 5 to be blown into the collection cylinder 15 for collection. After collection, the rotary motor 30 is turned off. At this point, the adsorption plate 31 and the squeezing plate 22 are at the top. The next time it is used, the rotary motor 30 must be started first. Due to the action of the reciprocating screw, the adsorption plate 31 and the squeezing plate 22 will move downwards. At this time, the drain valve 32 needs to be opened to drain the previous dissolved liquid. When the adsorption plate 31 and the squeezing plate 22 reach the bottom, the above steps are repeated.

[0045] Compared with existing technologies, this invention uses air-floating balls to prevent the hose from sagging in the middle when spraying large areas, resulting in better spraying effect. The mobile carts on both sides reduce the difficulty of manual operation and improve spraying efficiency. The collection tube can be used to collect the used hose and connecting air pipe.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
