Description
Technical Field
[0001] This utility model relates to the field of cotton planting technology, specifically a cotton dry-sowing wet-irrigation device. Background Technology
[0002] Dry-sowing and wet-emergence technology is an emerging cotton planting technique. This technique involves neither winter nor spring irrigation before cotton sowing. Instead, the land is prepared, mulch film and drip irrigation tape are laid, and cotton seeds are sown directly. Once the suitable emergence temperature is reached, a small amount of water is dripped under the film to ensure that the soil moisture under the film meets the requirements for cotton seed emergence. This technique not only saves a lot of water resources but also improves the emergence rate and reduces production costs, making it particularly suitable for cotton planting in arid desert regions.
[0003] Cotton dry-seeding and wet-harvesting irrigation requires not only water but also fertilizer or pesticides mixed in the water to increase crop yield. However, existing devices lack proper filtration of the water-fertilizer mixture. Over time, the irrigation device is prone to clogging of the irrigation head by particulate matter in the mixture, leading to reduced irrigation efficiency and uneven irrigation. Furthermore, because the irrigation device is used close to the ground, the irrigation head is easily invaded and adhered to by splashed soil or dust, causing blockage or contamination of the unused water-fertilizer mixture inside the device. To address these issues, we propose a cotton dry-seeding and wet-harvesting irrigation device. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in this embodiment, a cotton dry-seeding wet-output irrigation device includes a main pipe 1, a mounting frame 2 fixedly installed above the main pipe 1, an inlet pipe 3 fixedly installed above the mounting frame 2, multiple sets of equidistantly distributed outlet pipes 26 on the main pipe 1, a mounting plate 4 on the mounting frame 2, two sets of symmetrically distributed filter frames 5 embedded in the mounting plate 4, the mounting plate 4 being rotatably connected to the mounting frame 2 via a mounting shaft 10, a first gear 11 sleeved on the mounting shaft 10, a first rack 12 slidably installed inside the mounting frame 2, and a first cylinder fixedly installed inside the mounting frame 2. 13. The first rack 12 is connected to the output end of the piston 29 rod of the first cylinder 13. The first rack 12 is meshed with the first gear 11. A fixed frame 17 is slidably installed on the mounting frame 2. A cleaning brush 18 is provided inside the fixed frame 17. The cleaning brush 18 is in contact with the surface of the filter frame 5. The cleaning brush 18 is rotatably connected to the fixed frame 17 through a fixed shaft 31. A support frame 27 is fixedly installed inside the water outlet pipe 26. A piston 29 is slidably sleeved on the support frame 27. The water-fertilizer mixture enters the main pipe 1 through the water inlet pipe 3 and completes the wet discharge of cotton dry sowing through the water outlet pipe 26. During irrigation, the water-fertilizer mixture passes through the inlet pipe 3 into the main pipe 1 and is filtered by the filter frame 5. Impurities and particulate matter in the water-fertilizer mixture remain on the filter frame 5. Each of the two sets of filter frames 5 has two symmetrically distributed slots 6. Two sets of symmetrically distributed retaining rings 7 are slidably installed inside the mounting frame 2. The two sets of retaining rings 7 are correspondingly positioned to the filter frames 5, and both sets of retaining rings 7 are movably engaged with the filter frames 5 through the slots 6. A connecting pipe 8 is provided between each set of retaining rings 7 and the mounting frame 2. Both ends of the connecting pipe 8 are fixedly connected to the mounting frame 2 through the retaining rings 7. The device contains two sets of symmetrically distributed bidirectional screws 9. The two ends of the two sets of bidirectional screws 9 pass through the mounting frame 2 and are rotatably connected to the mounting frame 2 through bearings. The two ends of the two sets of bidirectional screws 9 pass through two sets of retaining rings 7 and are threadedly connected to the two sets of retaining rings 7 respectively. Under the action of the bidirectional screws 9, the two sets of retaining rings 7 are engaged with the filter frame 5 through the retaining groove 6, realizing the connection between the water outlet pipe 26, the filter frame 5 and the lower main pipe 1. Under the action of the bidirectional screws 9, the retaining rings 7 can release the closed connection with the filter frame 5, so that the mounting plate 4 can rotate on the mounting frame 2 to complete the replacement of the two sets of filter frames 5.
[0023] like Figure 2 , Figure 3 and Figure 4As shown, both sets of filter frames 5 are rotatably connected to the mounting plate 4 via a rotating shaft. A second gear 14 is sleeved on the filter frame 5. A second rack 15 is slidably installed in the mounting plate 4. A second cylinder 16 is fixedly installed in the mounting plate 4. The second rack 15 is connected to the output end of the piston 29 rod of the second cylinder 16. The second rack 15 meshes with the second gear 14. A third gear 19 is sleeved on the fixed shaft 31. A third rack 20 is slidably installed in the fixed frame 17. The third rack 20 meshes with the third gear 19. 9. Engaging connection: A flying disc 22 is rotatably mounted inside the fixed frame 17. A connecting rod 21 is provided between the flying disc 22 and the third rack 20. The two ends of the connecting rod 21 are rotatably connected to the third rack 20 and the flying disc 22 respectively via rotating shafts. The rotation of the mounting plate 4 realizes the conversion between the water outlet pipe 26 and the mounting frame 2 for the filter frame 5. After use, the filter frame 5, which is covered with impurities, rotates to the position corresponding to the cleaning brush 18. The activation of the second cylinder 16 in the mounting plate 4 drives the second rack 15 to slide, cooperating with the second gear 14 to realize the filter frame 5. The cleaning brush 18, made of soft silicone, does not obstruct the rotation of the filter holder 5. A motor in the fixing frame 17 drives the fly disk 22 to rotate. Under the action of the fly disk 22 and the connecting rod 21, the third rack 20 slides back and forth in the fixing frame 17. This, combined with the meshing third gear 19, causes the fixed shaft 31 to drive the cleaning brush 18 to rotate back and forth on the fixing frame 17, thus cleaning impurities adhering to the filter holder 5. Two sets of symmetrically distributed sliding rods 23 are fixedly installed inside the mounting frame 2. The fixing frame 17 and the sliding rods 23 are slidably sleeved together. A first spring 24 is sleeved on the slide rod 23. The two ends of the first spring 24 are fixedly connected to the slide rod 23 and the fixing frame 17, respectively. A cam 25 is rotatably installed inside the mounting frame 2. The cam 25 is fitted against the fixing frame 17. At the same time, the motor in the mounting frame 2 drives the cam 25 to rotate. In conjunction with the slide rod 23 and the first spring 24, the fixing frame 17 drives the cleaning brush 18 above to slide back and forth on the mounting frame 2. The vibration of the cleaning brush 18 also pushes the filter frame 5, which is in contact with it, to vibrate. The impurities attached to the filter frame 5 are thoroughly cleaned.
[0024] like Figure 5As shown, a retaining ring 28 is fixedly installed inside the water outlet pipe 26. The piston 29 is movably engaged with the retaining ring 28. Two sets of symmetrically distributed second springs 30 are sleeved on the support frame 27. The two ends of the two sets of second springs 30 are fixedly connected to the piston 29 and the support frame 27, respectively. Under the action of the two sets of symmetrically distributed second springs 30, the piston 29 is engaged with the retaining ring 28, and the water outlet pipe 26 is in a closed state. Under the power of the water pump, the irrigation device flows out through the water outlet pipe 26. During the outflow of water, the piston 29 is squeezed, causing the two sets of second springs 30 to be compressed or stretched. The water outlet pipe 26 opens, and the water-fertilizer mixture successfully flows out to irrigate the cotton. When external mud and water enter the water outlet pipe 26, even if the piston 29 is pushed under the action of the retaining ring 28, it cannot enter the main pipe 1 or the irrigation device.
[0025] This utility model provides a cotton dry-seeding wet-output irrigation device. The specific working principle is as follows: A water-fertilizer mixture enters the main pipe 1 through the inlet pipe 3 and completes the cotton dry-seeding wet-output irrigation through the outlet pipe 26. During the process of the water-fertilizer mixture entering the main pipe 1 through the inlet pipe 3, it is filtered by the filter frame 5. Impurities and particulate matter contained in the water-fertilizer mixture remain on the filter frame 5. Two sets of retaining rings 7, under the action of the bidirectional screw 9, engage with the filter frame 5 through the retaining groove 6, realizing the connection between the outlet pipe 26, the filter frame 5, and the lower main pipe 1. Under the action of the bidirectional screw 9, the retaining rings 7... The closed connection to the filter holder 5 can be released, allowing the mounting plate 4 to rotate on the mounting frame 2 to switch between the two sets of filter holders 5. The rotation of the mounting plate 4 enables the switching of the filter holder 5 between the water outlet pipe 26 and the mounting frame 2. After use, the filter holder 5 with impurities will rotate to the position corresponding to the cleaning brush 18. The activation of the second cylinder 16 in the mounting plate 4 drives the second rack 15 to slide, which, in conjunction with the second gear 14, enables the filter holder 5 to flip. The cleaning brush 18 is made of soft silicone and will not obstruct the flipping of the filter holder 5. The motor in the fixing frame 17 drives the fly As disc 22 rotates, the third rack 20 slides back and forth in the fixed frame 17 under the action of disc 22 and connecting rod 21. This, in conjunction with the third gear 19 meshing with it, causes the fixed shaft 31 to drive the cleaning brush 18 to rotate back and forth on the fixed frame 17, thus cleaning impurities adhering to the filter frame 5 it is attached to. Simultaneously, the motor in the mounting frame 2 drives the cam 25 to rotate, which, in conjunction with the slide rod 23 and the first spring 24, causes the fixed frame 17 to drive the upper cleaning brush 18 to slide back and forth on the mounting frame 2. The vibration of the cleaning brush 18 also pushes the filter frame 5 it is attached to to vibrate. When the filter frame 5 is cleaned, the impurities attached to it are thoroughly removed. Under the action of two sets of symmetrically distributed second springs 30, the piston 29 engages with the retaining ring 28, and the water outlet pipe 26 is in a closed state. Under the power of the water pump, the water flows out through the water outlet pipe 26. During the water flow, the piston 29 is squeezed, causing the two sets of second springs 30 to be compressed or stretched. The water outlet pipe 26 opens, and the water-fertilizer mixture successfully flows out to irrigate the cotton. When external mud and water enter the water outlet pipe 26, even if the piston 29 is pushed under the action of the retaining ring 28, it cannot enter the main pipe 1 or the irrigation device.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
