Description

An underground layered irrigation system integrating fertilizer and water

technical field

The invention relates to an underground layered irrigation system integrating fertilizer and water, belonging to the technical field of water-saving irrigation.

Background technique

For a long time, my country has mainly used surface irrigation methods such as flood irrigation, furrow irrigation, and sprinkler irrigation to irrigate crops. Irrigation water penetrates from the ground to the roots of crops, and the roots of crops absorb water and fertilizers to meet their own growth and development. However, these irrigation methods cause More than half of the water and fertilizer wasted. However, the crop root system is irrigated in layers, and water and fertilizer are directly poured into the crop root system, which reduces the loss of water and waste of fertilizer, and can increase the utilization rate of water and fertilizer. In the current infiltration irrigation technology, the drip irrigation belt is buried under the soil and slowly transports water to the ground, but the equipment has a short service life and cannot be recycled for a long time.

A magnet 27 is arranged on the top of the water filling cylinder 28, and when the adjusting part 26 of the regulating rod is iron or a magnet, it can be used in conjunction with the magnet 27 to fix the position of the gasket after rotation.

The working principle of the present invention is:

The underground layered irrigation device 9 is buried below the soil layer, and the depth of burial and the length of the device are different according to different crops. When a certain crop is irrigated with fertilizer and water, the soluble fertilizer is first added to the mixing tank 15 of the fertilizer mixing device 1, and then clear water is added. The staff can grasp the manual stirring handle 12 or use the motor 17 to drive the rotating shaft 13 to rotate, and at the same time drive the stirring blade 16 on it to rotate to mix the fertilizer and water; after the water and fertilizer are mixed, open the valve Ⅰ18, and the flow meter Ⅰ19 records the flow of fertilizer and water , the fertilizer water enters the reservoir 2 through the main pipe I20;

When irrigating certain crops with clear water, the water storage device 5 can use the collected rainfall as irrigation water through the water diversion valve 21, or directly use tap water. After opening the valve III 24, the clear water enters the liquid storage tank 2 through the main pipe II 23, and the flow meter Ⅲ25 records the clear water flow.

After the clean water or fertilized water reaches the liquid storage tank 2, it enters the infusion branch pipe 6 through more than one water outlet port 3 provided at the bottom of the liquid storage tank 2, and the clean water or fertilized water flows into the underground layered irrigation device 9 through the valve II8, and the flow meter II7 records the flow;

The liquid that enters the underground layered irrigation device 9 is determined by the control rod which level of drip irrigation head is used for drip irrigation. When the first level drip irrigation head 31 is used for irrigation, the adjustment part 26 of the rotatable control rod drives the rotation of the rod 14 to drive the adjustment. The rotating washer Ⅰ10 is rotated so that the semicircle without holes on the adjustable rotating washer Ⅰ10 overlaps with the semicircle with holes on the fixed washer Ⅰ34, so that the liquid cannot enter the next stage through the rotating washer Ⅰ10 and the fixed washer Ⅰ34. Accumulate on the rotating gasket I10, and then enter into the four primary drip irrigation heads 31 through the infusion capillary 30; The semicircle with holes on gasket I34 overlaps, and the semicircle without holes on the rotatable gasket II38 overlaps with the semicircle with holes on the fixed gasket II37, so that water can pass through the rotating gasket I10 and the fixed gasket I34, but not through the movable gasket. Rotating washer Ⅱ38 and fixed washer Ⅱ37; when the three-stage drip irrigation head 33 needs water irrigation, the semicircle with holes on the rotating washer Ⅰ10 can be adjusted to overlap with the semicircle with holes on the fixed washer Ⅰ34 through the control lever, and the washer can be rotated at the same time The semicircle with holes on the piece II38 overlaps with the semicircle with holes on the fixed gasket II37, so that water can pass through the rotating gasket I10 and the fixed gasket I34, and can also pass through the rotating gasket II38 and the fixed gasket II37 to enter the three-stage drip irrigation head 33 ;

The liquid entering the infusion capillary 30 enters the hemispherical shell 39 through the filter 42. When the liquid is accumulated to a certain amount, the spring 40 is stretched and deformed, and the disc 41 moves down, thereby forming a gap with the hemispherical shell 39, and the liquid flows Through the hole on the perforated water sheet 43, it flows down into the cone shell 47. When the liquid increases, the hollow ball 44 floats upwards under the effect of buoyancy, and the liquid drips out through the drip irrigation hole 45 to drip irrigation the crops. When the irrigation is finished and the infusion capillary 30 has no liquid, the spring 40 returns to its original length, and the disc 41 connected to the lower end of the spring 40 rises further and returns to the position before the irrigation; the liquid in the cone shell 47 penetrates into the soil, and the hollow The ball 44 is not affected by buoyancy, but is downward by gravity, and returns to the position before irrigation, thereby preventing the dripper from being blocked.

After the irrigation is finished, close the valve Ⅰ18, the valve Ⅱ8, and the valve Ⅲ24; and repeat the above steps for the next irrigation.

The beneficial effects of the present invention are:

1. The system can freely adjust the amount of irrigation water, and can implement quantitative irrigation according to the different crops and the different water requirements of the crops;

2. The system can realize the mixing of water and fertilizer, and control the ratio of clean water and fertilizer solution; after the fertilizer solution is irrigated, water is added to irrigate, and the irrigation pipes are rinsed, which improves the utilization rate of fertilizer and also improves the utilization efficiency of irrigation water ; The mixing of water and fertilizer can be manually stirred, or it can be realized automatically by the stirring motor;

3. The system is equipped with an underground layered irrigation device, which can perform layered irrigation according to the growth of the root system in different growth stages of the crops; the length of the device is adjustable and is suitable for various crops; the selective opening and closing of the branch valve II can realize The deficit irrigation of crops can further promote the absorption of water and fertilizer by crops, and promote the growth and development of crops;

4. The underground layered irrigation device of the system is equipped with 3-level drip irrigation heads. When watering, the internal spring of the drip irrigation head stretches, and the connected disc ensures the uniform water flow; when the irrigation ends, the internal spring of the drip irrigation head shrinks, and the connected circle The sheet ensures that there is no water inside the dripper, avoiding the drip irrigation head from bursting in winter, and increasing the service life of the drip irrigation head;

5. The underground layered irrigation device of the system is equipped with 3-level drip irrigation heads, and a hollow ball is placed in the drip irrigation head; when watering, the hollow ball is buoyant and automatically floats up to complete drip irrigation; when the irrigation is finished, there is no water inside the drip irrigation head, and the hollow ball Automatically descend by gravity, thus blocking the drip irrigation hole, effectively preventing the drip irrigation head from clogging;

6. The layout of the infusion branch pipes of the system is adapted to local conditions, and can be laid randomly according to the terrain of the crop growing area and the crop planting method, and has a wide range of applications;

7. The operation of the system is relatively simple, the maintenance is relatively convenient, the service life of the device is long, and the labor input and labor intensity can be effectively reduced.
