Description

Technical Field

[0001] This utility model relates to the field of farmland water-saving irrigation and fertilization technology, specifically a farmland water-saving irrigation and fertilization device. Background Technology

[0002] Water-saving irrigation and fertilization in farmland is an agricultural management method that combines water-saving irrigation technology with precision fertilization. It can improve fertilizer utilization while reducing water consumption. The dissolved fertilizer solution is delivered directly to the soil near the crop roots, rather than the traditional method of flooding and spreading fertilizer. This method avoids the waste of water resources during transportation and infiltration, and allows nutrients to be precisely applied to the crop absorption area, reducing fertilizer loss and soil compaction. Ultimately, it achieves multiple goals of water conservation, fertilizer conservation, increased yield, and improved soil environment, and is an important technical means for efficient planting in modern agriculture.

[0003] When applying water-saving irrigation and fertilization to crops, pipes are installed above the crops, and water and fertilizer are mixed and sprayed onto the crops using nozzles. However, in actual use, continuous rainy weather after spraying can damage the cuticle of the leaves, leading to the invasion of pathogens and causing leaf rot. During the spraying process, wind can cause some fertilizer solution to drift to non-target areas, resulting in fertilizer dripping onto the ground and causing waste. Furthermore, the pipeline laying needs to be planned according to the shape of the plot and the crop layout. In areas with large slopes or scattered plots, the construction difficulty will increase significantly. In the later stage, the pipeline also needs to be regularly maintained to prevent blockage or damage. Therefore, we propose a water-saving irrigation and fertilization device for farmland. Summary of the Invention

[0004] The purpose of this invention is to provide a water-saving irrigation and fertilization device for farmland to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving irrigation and fertilization device for farmland, comprising a rectangular plate, several wheels mounted on the surface of the rectangular plate, a water bucket fixedly connected to the surface of the rectangular plate, a liquid pump fixedly connected to the surface of the rectangular plate, the input end of the liquid pump being connected to the water bucket, a fertilization structure provided on the surface of the rectangular plate, the fertilization structure including a column, the column being fixedly connected to the surface of the rectangular plate, several circular holes being opened on the surface of the column, a frame being slidably connected to the surface of the column, two fixing plates being fixedly connected to the surface of the frame, the two fixing plates being located on both sides of the column, pins slidingly penetrating the surfaces of the two fixing plates, the size of the pins being adapted to the size of the circular holes, extension plates being fixedly connected to both sides of the frame, nozzles being fixedly connected to the surface of the extension plates, transmission pipes being connected to the surface of the nozzles, a connecting box being connected to the end of the two transmission pipes away from the nozzles, a flexible tube being connected to the surface of the connecting box, the other end of the flexible tube being connected to the output end of the liquid pump.

[0006] The effects achieved by the above components are as follows: by setting up the fertilization structure, the height can be adjusted to achieve near-ground spraying, reducing the risk of leaf cuticle damage and pathogen invasion in rainy weather, while preventing fertilizer solution from drifting to non-target areas and reducing waste.

[0007] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the fixing plate, respectively.

[0008] The effect achieved by the above components is that the pin automatically inserts into the corresponding round hole of the column under the elastic force of the spring. The spring improves the stability of the pin inserted into the round hole, thereby preventing the pin from coming out of the round hole due to shaking.

[0009] Preferably, the arc surface of the transmission tube is fixedly connected to a plurality of limiting frames, and the limiting frames are fixedly connected to the surface of the frame.

[0010] The effect achieved by the above components is that the transmission tube remains stable under the fixing action of the limiting frame, thereby improving the transmission stability of the transmission tube.

[0011] Preferably, the surface of the nozzle is covered with a protective cover, and the protective cover is fixedly connected to the extension plate.

[0012] The effect achieved by the above-mentioned components is that during the fertilization process, the protective cover can push away the leaves and debris of crops, thereby preventing damage to the nozzle.

[0013] Preferably, the rectangular plate has an adjustment structure on its surface, the adjustment structure including two support arms, both of which are fixedly connected to the rectangular plate, and a rotating shaft is rotatably connected to the surface of the two support arms. Handrails are fixedly connected to both ends of the rotating shaft, and a gear is fixedly connected to the arc surface of the rotating shaft. A limit arm is fixedly connected to the surface of the rectangular plate, and a threaded rod is threaded through the surface of the limit arm. A retainer is rotatably connected to the end of the threaded rod near the gear, and the size of the retainer is adapted to the tooth size of the gear.

[0014] The effect achieved by the above components is that, by setting an adjustment structure, the height of the handrail can be adjusted to a suitable height for the operator, making it easier for the operator to carry out fertilization operations.

[0015] Preferably, the surface of the limiting arm has two guide rods that slide through it, and both guide rods are fixedly connected to the surface of the sleeve.

[0016] The effect achieved by the above components is that the ferrule will drive the guide rod to slide within the limiting arm during the movement of the ferrule, thereby limiting the movement path of the ferrule and preventing the ferrule from rotating during the movement.

[0017] Preferably, a turntable is fixedly connected to the end of the threaded rod away from the ferrule, and the cross-section of the turntable is in the shape of a cross.

[0018] The effect achieved by the above components is that the rotation of the turntable will drive the threaded rod to rotate, and the turntable facilitates the rotation of the threaded rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a fertilization structure to create a liquid pump on the surface of a rectangular plate. The pump, connected to a water tank via its input, draws out the water-fertilizer mixture from the tank. The output of the pump delivers the mixture to a connecting box via a flexible hose. The connecting box then distributes the mixture to transmission pipes on both sides, ultimately delivering it to a nozzle. This nozzle then moves the rectangular plate along the root path of the crop, evenly spraying the mixture onto the roots, thus fertilizing the crop. Adjusting the height allows for near-ground spraying, reducing the risk of leaf cuticle damage and pathogen invasion during rainy weather, while also preventing fertilizer from drifting to non-target areas and minimizing waste.

[0020] By setting an adjustment structure, the angle of the handrail can be adjusted by rotating it. The handrail drives the rotating shaft to rotate within the support arm. When the angle is appropriate, the rotating threaded rod moves within the limit arm. The threaded rod pushes the sleeve to engage with the gear, fixing the angle of the handrail and adjusting the height of the handrail to a height suitable for the operator, making it convenient for the operator to carry out fertilization operations.

[0024] Please see Figure 1-2 This utility model provides a technical solution: a water-saving irrigation and fertilization device for farmland, including a rectangular plate 1, with several wheels 2 mounted on the surface of the rectangular plate 1, a water bucket 3 fixedly connected to the surface of the rectangular plate 1, and a liquid pump 4 fixedly connected to the surface of the rectangular plate 1. The input end of the liquid pump 4 is connected to the water bucket 3. The surface of the rectangular plate 1 is provided with a fertilization structure 5. By setting the fertilization structure 5, the height can be adjusted to achieve near-ground spraying, reducing the risk of leaf cuticle damage and pathogen invasion in rainy weather, while also preventing fertilizer solution from drifting to non-target areas and reducing waste. The surface of the rectangular plate 1 is provided with an adjustment structure 6. By setting the adjustment structure 6, the height of the handle 63 can be adjusted to a suitable height for the operator, facilitating fertilization operations.

[0025] Reference Figure 3 and Figure 4As shown in this embodiment: the fertilization structure 5 includes a column 501, which is fixedly connected to the surface of the rectangular plate 1. The surface of the column 501 has several round holes 502. A frame 503 is slidably connected to the surface of the column 501. Two fixing plates 504 are fixedly connected to the surface of the frame 503. The two fixing plates 504 are located on both sides of the column 501. Pins 505 slide through the surfaces of the two fixing plates 504. The size of the pins 505 is adapted to the size of the round holes 502. Extension plates 506 are fixedly connected to both sides of the frame 503. Sprayers 507 are fixedly connected to the surface of the extension plates 506. Transmission pipes 508 are connected to the surface of the sprayers 507. The ends of the two transmission pipes 508 away from the sprayers 507 are connected to a connecting box 509. A hose 510 is connected to the surface of the connecting box 509. The other end of the hose 510 is connected to the output end of the liquid pump 4. A spring 511 is fitted onto the arc-shaped surface of the pin 505. Both ends of the spring 511 are fixedly connected to the pin 505 and the fixing plate 504, respectively. Under the elastic force of the spring 511, the pin 505 automatically inserts into the corresponding circular hole 502 of the column 501. The spring 511 enhances the stability of the pin 505 within the circular hole 502, preventing it from dislodging due to shaking. Several limiting brackets 512 are fixedly connected to the arc-shaped surface of the transmission pipe 508. The limiting brackets 512 are fixedly connected to the surface of the frame 503. The transmission pipe 508 remains stable under the fixing action of the limiting brackets 512, thereby improving the transmission stability of the transmission pipe 508. A protective cover 513 is fitted onto the surface of the nozzle 507. The protective cover 513 is fixedly connected to the extension plate 506. During fertilization, the protective cover 513 can push away crop leaves and debris, thus preventing damage to the nozzle 507.

[0026] Reference Figure 5 As shown, specifically, the adjustment structure 6 includes two support arms 61, both of which are fixedly connected to the rectangular plate 1. A rotating shaft 62 is rotatably connected to the surface of each support arm 61. Handrails 63 are fixedly connected to both ends of the rotating shaft 62. A gear 64 is fixedly connected to the arc surface of the rotating shaft 62. A limiting arm 65 is fixedly connected to the surface of the rectangular plate 1. A threaded rod 66 is threaded through the surface of the limiting arm 65. A retaining sleeve 67 is rotatably connected to the end of the threaded rod 66 near the gear 64. The size of the retaining sleeve 67 matches the tooth size of the gear 64. Two guide rods 68 slide through the surface of the limiting arm 65. Both guide rods 68 are fixedly connected to the surface of the retaining sleeve 67. During movement, the retaining sleeve 67 drives the guide rods 68 to slide within the limiting arm 65, thus limiting the movement path of the retaining sleeve 67 and preventing it from rotating during movement. A turntable 69 is fixedly connected to the end of the threaded rod 66 away from the ferrule 67. The cross-section of the turntable 69 is in the shape of a cross. The rotation of the turntable 69 will drive the threaded rod 66 to rotate, so that the turntable 69 can facilitate the rotation of the threaded rod 66.

[0027] Working Principle: When fertilizing crops, first pour water and dissolved fertilizer into the water tank 3 of the device in the correct proportion to prepare the materials for irrigation and fertilization. Then, pull the pin 505, which will slide within the fixed plate 504 and disengage from the round hole 502. The movement of the pin 505 will stretch the spring 511. After the pin 505 disengages from the round hole 502, adjust the position of the sliding frame 503 on the surface of the column 501 according to the height of the crops. When the appropriate height is reached, release the pin 505. Under the elastic force of the spring 511, the pin 505 will automatically insert into the corresponding round hole 502 of the column 501, fixing the frame 503. As the frame 503 moves, it will also drive the extension plates 506 on both sides to move simultaneously. The movement of the extension plates 506 will drive the nozzles 507 to move simultaneously, thereby adjusting the nozzles 507. The spraying height is adjusted to avoid waste or poor effect due to improper spraying. Then, the liquid pump 4 on the surface of the rectangular plate 1 is started. The liquid pump 4 is connected to the water tank 3 through the input end, and the suction force is generated to draw out the water-fertilizer mixture in the tank. The output end of the liquid pump 4 delivers the water-fertilizer mixture to the connecting box 509 through the hose 510. The connecting box 509 then distributes the mixture to the transmission pipes 508 on both sides. The transmission pipes 508 are kept stable under the fixing action of the limit frame 512. Finally, the water-fertilizer mixture is delivered to the nozzle 507. Then, the rectangular plate 1 is pushed to move along the root path of the crop. The nozzle 507 will spray the water-fertilizer mixture evenly on the roots of the crop, thereby fertilizing the crop. During the fertilization process, the protective cover 513 can push away the leaves and debris of the crop, thereby preventing damage to the nozzle 507.

[0028] When the fertilizing device needs to be pushed to apply fertilizer, first rotate the turntable 69. The rotation of the turntable 69 will drive the threaded rod 66 to rotate. The rotation of the threaded rod 66 will move within the limiting arm 65 by means of the thread. The movement of the threaded rod 66 will cause the ferrule 67 to move away from the surface of the gear 64. When the ferrule 67 moves to the appropriate position, rotate the handle 63 to adjust the angle. The handle 63 will drive the rotating shaft 62 to rotate within the support arm 61. When the angle is appropriate, rotate the turntable 69 to move the threaded rod 66 within the limiting arm 65. The threaded rod 66 will push the ferrule 67 to engage with the gear 64. During the movement of the ferrule 67, it will drive the guide rod 68 to slide within the limiting arm 65. The guide rod 68 will limit the movement path of the ferrule 67, thereby preventing the ferrule 67 from rotating during movement. Fix the angle of the handle 63, thereby adjusting the height of the handle 63 to a suitable height for the operator, making it convenient for the operator to carry out fertilization operations.
