Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation and fertilization equipment technology, specifically to an integrated irrigation and fertilization device suitable for various terrains. Background Technology

[0002] With the continuous advancement of water conservancy projects such as the Yellow River irrigation project, which benefit the people, irrigation conditions for farmland and paddy fields in rural areas have been significantly improved. However, shortcomings in the water and fertilizer application process have become increasingly prominent, becoming a key bottleneck restricting the improvement of agricultural production efficiency. Currently, most rural areas still lack professional water and fertilizer mixing equipment, and fertilization operations rely heavily on manual labor, resulting in many prominent problems.

[0003] When manually mixing fertilizers, farmers often rely on experience to estimate dosages, lacking scientific measurement standards. This leads to significant deviations in the water-to-fertilizer ratio, resulting in either excessively high fertilizer concentrations that burn seedlings or insufficient concentrations that fail to meet crop growth needs, resulting in generally low fertilizer utilization rates. Furthermore, manual mixing leads to poor uniformity and uneven nutrient distribution, directly impacting crop growth and yield stability. In addition, the traditional method of separating irrigation and fertilization requires substantial manpower for transporting fertilizers, mixing solutions, and manually controlling irrigation. This is not only labor-intensive but also extremely inefficient, often causing farmers to miss the optimal fertilization time, especially in large-scale planting areas.

[0004] Existing irrigation facilities mostly only have a single water delivery function and fail to effectively connect with the fertilization process. Their automation level is severely insufficient, and they cannot dynamically adjust water and fertilizer supply according to crop growth stages and soil moisture conditions. In addition, rural terrain is complex, with different landforms such as plains, hills, mountains, paddy fields, and lakes having different requirements for the adaptability of irrigation and fertilization equipment. Existing simple tools are difficult to meet the needs of multi-terrain operations.

[0005] Driven by the dual demands of agricultural modernization and water-saving agriculture, traditional manual fertilization methods are no longer suitable for current production scenarios. Therefore, there is an urgent need to develop an integrated irrigation and fertilization machine that combines controllable pumping, precise water and fertilizer mixing, intelligent ratio control, and controllable fertilizer discharge across various terrains. This automated technology will address pain points such as difficulty in ratio control and low efficiency, achieving simultaneous and precise water and fertilizer supply, and contributing to cost reduction, efficiency improvement, and sustainable development in agriculture.

[0031] The working process of this invention is as follows: (1) When working in the land ditch irrigation and fertilization mode: First, attach the towing and trailer to the rear of the vehicle, such as an agricultural electric tricycle; tow the device of the present invention to the front of the ditch, untie the towing and trailer, manually push the device across the ditch, and pull up the wheel brakes. Then turn on the power of console 2. When the power indicator light 201 lights up, press the button to lower the retractable water pumping pipe 3 and the retractable fertilizer draining pipe 305, and place the water pumping bowl 6 and the fertilizer draining bowl 7 into the irrigation water source in the ditch. Open the inlet cover 102 and add an appropriate amount of fertilizer into the water-fertilizer mixing tank 1; Turn on the water pump controller 302 and start the water pump 301. After the irrigation water passes through the three-stage filtration of the water pump bowl 6, it enters the water-fertilizer mixing tank 1 through the water inlet check valve 304, so that the water and fertilizer ratio in the water-fertilizer mixing tank 1 reaches the set value (the specific value can be determined by the concentration sensor 109 displayed on the display screen 202). Start the drive motor 108, set the speed and continuously stir to completely dissolve the fertilizer in the water; Open the fertilizer discharge controller 307, start the pressure regulating fertilizer discharge pump 306, and control the water-fertilizer mixture to flow out of the water-fertilizer mixing tank 1 through the fertilizer discharge one-way valve 309 at the set flow rate. After passing through the fertilizer discharge bowl 7 for secondary separation, it is integrated into the irrigation water source. The water level is monitored by the radar level gauge 110 and observed on the display screen of the control console 2. When the water-fertilizer mixture in the water-fertilizer mixing tank 1 is discharged to 2 / 3, fertilizer can be added to the water-fertilizer mixing tank 1. At the same time, the fertilizer control pump 301 is controlled by the control console 2 to keep working continuously to ensure that the water-fertilizer mixture in the water-fertilizer mixing tank 1 maintains dynamic balance. After the fertilization work is completed, continue to pump an appropriate amount of irrigation water into the water-fertilizer mixing tank 1, clean the inner wall of the tank by stirring, and then drain the cleaning water. After the cleaning work is completed, turn off the water pump controller 302, turn off the fertilizer discharge controller 307, turn off the drive motor 108, and control the retractable water pump pipe 3 and the retractable fertilizer discharge pipe 305 to retract back into the workbench 4. Turn off the power to console 2. After the power indicator light goes out, close the inlet cover 102 and attach the towing and trailer components back to the vehicle.

[0032] (2) When the pond fertilization operation mode is used, the traction device is first attached to the stern of the boat and the device is pulled into the pond. Because the closed inner cavity of the carriage 5 is filled with dry light gas, the carriage 5 can float on the water surface in the pond. If a fixed operation is to be performed, crank the handle 401 to place the lower end of the silicone hose 405 and the bionic suction cup 406 into the pond, so that the bionic suction cup 406 is attached to the metal or non-metal structure at the water source gate in the pond. Start the vacuum generator 404 to achieve suction cup adsorption. Then repeat the same steps as in the land ditch irrigation and fertilization operation mode. To carry out mobile operations, attach the device to the stern of the boat and tow it to the pond. Turn on the power to the control panel 2 and wait for the power indicator light to illuminate. Then, start the retractable water pumping pipe 3 and the retractable fertilizer discharge pipe 305, and place the water pumping bowl 6 and the fertilizer discharge bowl 7 into the pond water. Then, repeat the same steps as in the land ditch irrigation and fertilization operation mode.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort.
