Description

Technical Field

[0001] The invention belongs to the technical field of irrigation equipment, and in particular relates to a water-fertilizer system with a self-adaptive adjustment function. Background Art

[0002] In traditional agricultural production, the application of water and fertilizer mainly depends on manual control and farmers' planting experience, which often leads to insufficient or excessive application of water and fertilizer, thus affecting the growth and yield of crops. At the same time, manual control also requires a lot of manpower and time costs, and cannot achieve large-scale and efficient agricultural production.

[0003] With the continuous advancement of science and technology and the development of agriculture, in order to achieve better water and fertilizer effects, reduce the environmental problems caused by unreasonable fertilization on the basis of ensuring agricultural production, and achieve the purpose of irrigation that saves water and fertilizer. People have proposed a new concept of "water-fertilizer integration system". The narrow meaning of water-fertilizer integration is to combine micro-irrigation and fertilization with the help of micro-irrigation system, use the water in the micro-irrigation system as a carrier, fertilize while irrigating, realize the integrated utilization and management of water and fertilizer, and supply water and fertilizer in the soil in an optimized combination state for crops to absorb and utilize. In my country, micro-irrigation fertilization is also called "water-fertilizer integration technology", which has received widespread attention and application worldwide. However, the existing water-fertilizer integration system still has some shortcomings when used, such as: 1. The existing integrated water and fertilizer system has poor intelligent control performance during use and cannot analyze and adjust according to the user's irrigation mode. The effect of water and fertilizer ratio decision-making needs to be further improved. 2. In the process of water-fertilizer ratio nutrient solution in the water-fertilizer integrated system, because the back end is mostly drip irrigation belt, the drip irrigation aperture is small. In the process of drip irrigation, the traditional water source is mostly a pool with more impurities. After the disc filter, gravel filter and mesh filter filter, the water source has a clean water source. However, in the process of water-fertilizer ratio, there will still be impurities, whether it is solid fertilizer or liquid fertilizer. Among them, the impurities are already small, but there is still a risk of clogging the drip irrigation hole; Therefore, it is urgent to design a new type of water-fertilizer system with adaptive adjustment and cleaning functions to solve the problems existing in the above-mentioned prior art.

The water-fertilizer system with adaptive regulation function according to claim 1, characterized in that: The filtering mechanism (2) comprises a centrifugal filter (21), a mesh filter (22) and a gravel filter (23); the centrifugal filter (21) is arranged on a side close to the water inlet pipe (11), and the mesh filter (22) is arranged between the centrifugal filter (21) and the gravel filter (23).

9. The water-fertilizer system with adaptive regulation function according to claim 1, characterized in that: The water-soluble mechanism (5) comprises a plurality of water-soluble tanks (51); the upper liquid inlet end of the water-soluble tank (51) is connected to a branch of the water-soluble pipeline (3), and a first flow control valve (31) is provided on the connecting branch of the water-soluble pipeline (3) and the water-soluble tank (51); the lower liquid discharge branch (52) of the water-soluble tank (51) is connected to a water fertilizer supply pipeline (9), and a second flow control valve (53) is also provided on the liquid discharge branch (52); and a stirring mechanism is also provided in the water-soluble tank (51).

10. The water-fertilizer system with adaptive regulation function according to claim 1, characterized in that: The use process of the water-fertilizer system includes: Step 1: Connect the water inlet end of the water inlet pipe to the water source, pump water into the filtering mechanism through a water pump, and perform centrifugal filtration, mesh filtration and gravel filtration on the connected water source through a centrifugal filter, a mesh filter and a gravel filter in sequence; Step 2: Then, the filtered water source is introduced into the water-soluble tank through the water-soluble pipeline, and the fertilizer in the water-soluble tank is dissolved by the stirring mechanism. The dissolved water-fertilizer liquid is discharged into the water-fertilizer supply pipeline through the branch pipe at the lower end of the water-soluble tank, and flows into the outer shell through the water-fertilizer supply pipeline, and is mixed with the clean water discharged into the outer shell through the water source supply pipeline in proportion; Step 3: When the clean water and fertilizer liquid enter the outer shell, they act on the inclined mixing blades, which in turn drives the entire transmission rod and the mixing blades to rotate. The shape of the mixing blades is used to fully mix the clean water and fertilizer liquid that enter, and finally they are filtered through the filter and enter the dropper for use.
