Description

Technical Field

[0001] The invention relates to the field of agricultural equipment, and in particular to a fertilizer-pesticide integrated drip irrigation device for agricultural planting. Background Art

[0002] Water-fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. Water-fertilizer integration is to use a pressure system to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop types, and then mix them with irrigation water through a controllable pipeline system to supply water and fertilizer. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipelines and drippers to evenly, regularly and quantitatively infiltrate the root development and growth area of ​​the crop, so that the main root soil always maintains looseness and appropriate water content; at the same time, according to the fertilizer requirements of different crops, soil environment and nutrient content, the water requirements of crops in different growth periods, and the fertilizer requirements, the demand design for different growth periods is carried out, and water and nutrients are provided to crops directly in a regular and quantitative manner in proportion.

[0003] However, in the actual material flow, the overall device designed for automation will produce a long retention time when storing liquid pesticides and fertilizers. For example, the public technology of patent number CN219555659U involves stirring the mixed liquid in the box, but a certain degree of liquid stratification or precipitation caused by temperature will also occur in the tank for storing fertilizers and pesticides. If an internal stirring device is still added, not only is the cost-effectiveness low, but the continuous stirring will also cause a certain degree of liquid emulsification, which will also affect the flow rate and pipeline blockage of the pipeline. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example 1

[0027] like Figure 1 As shown, the conventional design includes a fertilizer and medicine tank and a water-fertilizer storage tank 2. The water pump mainly pumps water into the water-fertilizer storage tank 2 through a water pipe 1 to complete the storage of mixed medicine, fertilizer and water, and then the liquid is extracted from the drip irrigation pipe 201 as a whole through an electrically controlled liquid pump to achieve irrigation.

[0028] On this basis, if Figure 1-3As shown, the fertilizer and medicine tanks provided may be the first fertilizer and medicine tank 3 and the second fertilizer and medicine tank 301, which store liquid pesticides and fertilizers respectively. The H-shaped pipeline is connected between the fertilizer and medicine tank and the water pipe 1 based on the first pipeline 4, the second pipeline 401 and the connecting pipe 402. During normal operation, the control valves on the first pipeline 4 and the second pipeline 401 are opened, and the water pipe 1 directly contacts the liquid pesticides and fertilizers. The inner walls of the first pipeline 4, the second pipeline 401 and the connecting pipe 402 are all provided with spiral protrusions 408, and the discharged liquid will contact the water in a spiral shape to obtain a greater impact force to mix the water in the water pipe 1;

[0029] When the pesticide needs to be mixed separately, the second control valve 405 and the water pipe valve 407 are closed. At this time, the water will directly contact the pesticide from the first pipe 4, and go to the second pipe 401 from the connecting pipe 402, until it returns to the water pipe 1 through the third control valve 406. This method allows the water and the pesticide to be mixed inside the H-shaped pipe of the spiral protrusion 408;

[0030] When it is necessary to mix fertilizer separately, only the first control valve 403 and the water pipe valve 407 are closed. At this time, the water source will still flow according to the above process, and only the valve at the second fertilizer tank 301 is opened, so the fertilizer can also be mixed with the water source in the second pipe 401 based on the spiral protrusion 408;

[0031] Because the fertilizer and medicine tank is provided with an air pump 5, when the air pump 5 pumps gas into the gas delivery pipe 501, a gas-tight space is provided at the fixed disk 502 at the bottom, and a dynamic seal connection is formed between the fixed disk 502 and the rotating disk 503. At this time, the rotating disk 503 will discharge gas from the corresponding position of the gas outlet 504 at the bottom. Figure 3 As shown, after the air is discharged in opposite directions from the left and right sides of the air outlet 504, the rotating disk 503 itself will generate a force couple and rotate. After the rotation, the rotating jet generated by the gas will continuously form rising bubbles in the liquid. Because the inlet pipe 8 can be in a sealed state based on the valve, when the air pressure inside the fertilizer and medicine tank increases, the internal liquid will be pressed toward the water pipe for discharging the liquid. Because the entire interior is in a static drainage state, the flow rate of the water pressure is small. At this time, the structure of the spiral protrusion 408 will thin the fluid boundary layer and increase the flow rate of the liquid or viscous liquid. Driven by the negative pressure of the fast flow rate formed by the water pipe 1, the normal liquid or viscous liquid inside the fertilizer and medicine tank will contact the water source at a faster flow rate. After the fertilizer and medicine tank completes a drainage work, the internal pressure can be discharged from the pressure relief valve at the inlet pipe 8 without continuous high pressure requirements.

[0032] Furthermore, a fixed pipe 6 connected to the water pipe 1 is provided inside the water-fertilizer storage tank 2, and a constant temperature module 9 is provided on the top side of the fixed pipe 6. Figure 5-6As shown, the constant temperature module 9 can be a heat pump or a semiconductor heating matrix, and an external heat exchange effect is formed by a heat dissipation structure extending to the outside;

[0033] Due to the impact of water sources in the pipeline, heating of the water pump or environmental influences, the temperature of the water, fertilizer and medicine after mixing will eventually change to a certain extent. Therefore, a constant temperature module 9 is also designed to directly exchange heat through the temperature conducting plate 11 and the fixed pipe 6, and maintain a certain degree of temperature in the internal space to avoid the internal temperature of the water fertilizer storage tank 2 being too high or too low; at the same time, based on the pressure of the water source output by the water pipe 1, a telescopic spring 10 and a temperature conducting plate 11 are also provided. Figure 5 As shown, the expansion of the liquid outlet 601 is increased based on the water pressure. When the water pressure is high, the liquid outlet 601 will be close to the left side, and when the water pressure is low or there is no water pressure, it will be close to the right side. This method can block the space between the water pipe 1 and the water and fertilizer storage tank 2 when no water pressure is generated, so as to prevent the volatile gas inside the water and fertilizer storage tank 2 from entering the water pipe 1, and when the water pipe 1 is equipped with an automatic backwashing or self-cleaning filter, it can avoid affecting the water and fertilizer storage tank 2.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
