Technical Field

[0001] This invention relates to the field of irrigation technology, specifically to an integrated intelligent irrigation and drainage conveying device for paddy fields. Background Technology

[0002] Paddy fields are divided into two categories according to their water source: irrigated paddy fields and rain-fed paddy fields. Irrigated paddy fields refer to cultivated land with a guaranteed water source and irrigation facilities, which can be irrigated normally in normal years and are used to grow aquatic crops. Rain-fed paddy fields refer to cultivated land without irrigation facilities, which mainly rely on natural rainfall and are used to grow aquatic crops such as rice, lotus root, and rush grass. Irrigated paddy fields require the assistance of irrigation devices during use. For example, an existing automated irrigation device for paddy fields and its usage method are disclosed in application number CN202410131565.7. This patent uses a second motor to simultaneously drive multiple nozzles to move and push a sliding plate to squeeze and spray water. However, during use, it is inconvenient to monitor the water level inside the paddy field in real time, thus failing to intelligently switch between irrigation and drainage based on the water level. This can easily lead to excessive or insufficient water in the paddy field, affecting crop growth.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. An integrated irrigation and drainage mechanism is set up. Through the cooperation of an integrated irrigation and drainage pump, self-priming pipe, booster discharge pipe, tee pipe, irrigation pipeline and drainage pipeline, it is convenient to transport river water. At the same time, a two-way hydraulic tie rod drives a concave traction slide, and the rotation of the sealing steering ball head in the guide ball valve seat is controlled by the traction rotating plate and the valve rotating plate, which quickly adjusts the water flow direction in the tee pipe. This allows the device to seamlessly switch between irrigation and drainage functions, improving the adaptability and reliability of operation. The liquid level connecting water tank is lowered by pushing the height adjustment rod, which makes it easy to adjust the bottom of the liquid level connecting water tank to fit the bottom of the paddy field. During the lifting and adjustment process, the sliding connecting sleeve maintains the connection with the irrigation and drainage pipes, which facilitates irrigation and drainage. By linking the water level-connected tank, the limiting float plate, the real-time water level push rod, the adjusting baffle plate, and three touch-sensitive squeezing blocks, the water level inside the paddy field is monitored in real time. When the water level rises or falls, the limiting float plate rises or falls accordingly, pushing the real-time water level push rod and the adjusting baffle plate to move, thereby triggering the intelligent control switch. Based on the water level, the integrated irrigation and drainage pump is automatically turned on or off, and the direction of water flow inside the two three-way pipes is changed simultaneously. This achieves intelligent monitoring and control of the paddy field water level, reducing the adverse effects of excessively high or low water levels, improving the intelligence level of the device, and reducing human intervention.

[0015] 2. An automatic fertilizer-water mixing and preparation mechanism is set up. Through the cooperation of power transmission gears, water injection splicing drum, power transmission sprocket and feeding transmission chain, the power of the bidirectional drive motor driving the self-priming pump body to pump water is reused and transmitted. At the same time, the electric contact adjustment rod moves the push positioning plate and the limit drive shaft sleeve to contact the positioning drive cylinder, so that the two planar transmission gears mesh, further transmitting power, which facilitates the driving of the power transmission connecting rod and the uniform conveying auger to convey the fertilizer evenly into the horizontal mixing drum for easy mixing with water. Simultaneously, the water-filling splicing drum rotates, driving the hydraulic drive wheel, horizontal transmission rod, and spiral mixing blades to rotate, improving the mixing effect of water and fertilizer. The fertilizer is then discharged through the outlet connection drum, and a static mixer is used for secondary mixing during the discharge process, further enhancing the fertilizer preparation effect. This facilitates the conversion of irrigation water into fertilizer, improving the degree of automation. In addition, the flowing water propels the hydraulic drive wheel to rotate, thereby assisting the bidirectional drive motor in driving the water-filling splicing drum, improving energy utilization.

[0016] In summary, by combining an integrated irrigation and drainage mechanism with an automatic fertilizer and water mixing and preparation mechanism, intelligent integration of paddy field irrigation, water level control, and fertilizer and water preparation is achieved. This allows for automatic and seamless switching between irrigation and drainage modes based on real-time water levels within the paddy field, enabling precise control of water resources. Furthermore, it allows for the utilization of power and water as needed to automatically complete fertilizer input and mixing, improving the efficiency and effectiveness of water and fertilizer utilization, thereby reducing manual intervention and energy consumption.

One end of the static mixer 422 is embedded inside the irrigation pipe 305.

[0022] The working principle and usage process of this invention are as follows: First, the overhead support 1 is installed next to the embankment of the paddy field. Then, the height adjustment rod 319 is rotated to push the liquid level connecting water tank 320 down, so that the liquid level connecting water tank 320 is fixed inside the paddy field. Then, a water pumping pipe is connected to one end of the self-priming pump body 315 and the other end of the water pumping pipe is connected to the inside of the river channel. Then, the bidirectional drive motor 314 is started to drive the turbine inside the self-priming pump body 315 to rotate, so as to draw water from the inside of the river channel. Through the cooperation of the river water delivery pipe 316 and the water injection splicing rotating drum 413, the river water is sent into the horizontal mixing drum 317. Next, the integrated irrigation and drainage pump 301 is started, and the water inside the horizontal mixing drum 317 is pumped out through the cooperation of the self-priming pipe 302, the three-way pipe 304 and the irrigation pipe 305. Then, through the cooperation of the pressurized discharge pipe 303, another three-way pipe 304 and another irrigation pipe 305, the water is sent into the liquid level connecting water tank 320 through the sliding connecting sleeve 322, so that the water can accumulate inside the liquid level connecting water tank 320 and then enter the paddy field through the water conveying connecting pipe 321 for flood irrigation. Meanwhile, because the water supply connecting pipe 321 makes the water level inside the liquid level connecting tank 320 parallel to the water level inside the paddy field, it is convenient to push the limiting floating plate 325 to rise inside the liquid level connecting tank 320 after the water level rises, and push the adjusting plate 331 to rise through the real-time water level push rod 324, so as to monitor the water level height in real time. When the adjustment plate 331 moves to the middle position of the water level monitoring box 323, the adjustment plate 331 pushes the touch extrusion block 329 to slide along the outside of the limit anti-deviation rod 328, forcing one end of the touch extrusion block 329 to slide inside the control installation channel 326 and contact one end of the intelligent control switch 327, so as to shut down the irrigation and drainage integrated pump 301 in time, stop irrigation, and prevent excessive irrigation water from overflowing the paddy field and causing waste. Then, during the rainy season, when there is excessive rainfall, the water level inside the paddy field rises, pushing the limit floating plate 325, the real-time water level push rod 324, and the adjusting plate 331 to rise continuously. This forces the adjusting plate 331 to push the uppermost touch-sensitive squeezing block 329 inside the water level monitoring box 323 to slide, thereby pressing the uppermost intelligent control switch 327, activating the extension of the bidirectional hydraulic pull rod 308, and pushing the two concave traction slides 309 to slide in opposite directions on the flow direction adjustment frame 307. Then, through the traction rotating connecting plate 310, the valve rotating plate 313 is pulled to rotate, causing the sealing steering ball head 312 to rotate inside the guide ball valve seat 311, simultaneously adjusting the state of the four guide ball valve seats 311 and switching the water flow direction inside the two three-way pipes 304. At the same time, the integrated irrigation and drainage pump 301 is started, which facilitates the drainage pipe 306 at one end of the tee pipe 304 on the self-priming pipe 302 and the sliding connecting sleeve 322 to draw out the water inside the water tank 320 and then discharge it into the river through the drainage pipe 306 at one end of the tee pipe 304 on the pressurized discharge pipe 303 to drain the water and reduce the water level in the paddy field in time to prevent the water level from being too high. When the water level inside the paddy field drops, the limiting floating plate 325 loses the buoyancy of the water and, by its own weight, lowers the water level real-time push rod 324 and the adjusting plate 331. This pushes the touch-sensitive squeezing block 329 at the bottom inside the water level monitoring box 323 to slide along the outside of the limiting anti-deviation rod 328 and contact the intelligent control switch 327 at the bottom. This causes the bidirectional hydraulic pull rod 308 to retract and reset. Then, through the cooperation of the concave traction slide 309, the traction rotating connecting plate 310, and the valve rotating plate 313, the sealing steering ball head 312 is driven to rotate, switching the water flow direction inside the two three-way pipes 304. At the same time, the irrigation and drainage integrated pump 301 is restarted, and the water is transported back to the liquid level connecting water tank 320 through the irrigation pipe 305 to replenish the water inside the paddy field and prevent the water inside the paddy field from becoming too low. Next, during irrigation, the electric contact adjustment rod 410 moves the push positioning plate 408 and the limit drive bushing 407 along the outside of the power transmission link 406, so that the planar transmission gear 412 on the limit drive bushing 407 meshes with the planar transmission gear 412 on the positioning drive cylinder 411. Then, through the cooperation of the power transmission gear 416, when the pump shaft inside the self-priming pump body 315 is rotated by the bidirectional drive motor 314, the power can be transmitted to drive the water injection splicing drum 413 to rotate. At the same time, through the cooperation of the power transmission sprocket 414 and the feeding transmission chain 415, the power is transmitted a second time to drive the positioning drive drum 411 to rotate. Then, the positioning drive drum 411 drives the limit drive bushing 407, the power transmission connecting rod 406 and the uniform conveying auger 405 to rotate through the planar transmission gear 412, so as to uniformly convey the fertilizer inside the fertilizer storage tank 401, so that the fertilizer moves along the fertilizer conveying pipe 402 and enters the discharge connection channel 403. Then, guided by the guide baffle 404, it falls into the horizontal mixing drum 317 for mixing. At the same time, the guide baffle 404 can block the splashed water during the mixing process to prevent water from entering the fertilizer conveying pipe 402. Next, when the water-filling splicing drum 413 rotates, it drives the hydraulic drive wheel 417, the transverse transmission rod 418 and the spiral stirring blade 419 to rotate, stirring and mixing the water and fertilizer that enter the horizontal mixing drum 317, so that the fertilizer and water are combined to prepare fertilizer solution. Then, through the cooperation of the water outlet connecting drum 420, the mixed fertilizer solution is conveniently sent into the irrigation pipe 305 for subsequent transportation. At the same time, during the transportation process, the fertilizer solution is mixed a second time by the static mixer 422, which further improves the mixing effect, prevents fertilizer residue, and reduces waste. Finally, when the river water transported by the self-priming pump body 315 enters the horizontal mixing drum 317 through the water injection splicing drum 413, the flowing water pushes the hydraulic drive wheel 417 to rotate, thereby assisting the bidirectional drive motor 314 in driving the water injection splicing drum 413, which in turn drives the transverse transmission rod 418 and the spiral stirring blade 419 to rotate, ensuring the stirring effect of the spiral stirring blade 419. Through the cooperation of the power transmission sprocket 414, the feeding transmission chain 415 and the limit drive bushing 407, the uniform conveying auger 405 can be driven to transport fertilizer, improving the energy utilization rate.
