Description

Technical Field

[0001] The invention belongs to the technical field of agricultural fertilization equipment, and in particular relates to a novel water-fertilizer conveying system and a working method thereof. Background Art

[0002] In natural ecological planting and breeding, although there is a technology to make organic fertilizer from organic waste generated in planting and breeding, the transportation of the finished organic fertilizer is a big problem, especially for the transportation of liquid fertilizer in the form of solid-liquid mixture, which contains a large amount of solid matter and is very easy to clog the fertilizer delivery pipe during the transportation process.

[0003] In order to solve the above problems, it is often necessary to perform multiple filtration and aging to remove the solid matter in the liquid fertilizer for easy transportation. However, this method has the following problems: (1) Many of the solid matter are nutrients that are beneficial to plant growth, resulting in a decrease in the effect of the liquid fertilizer after filtration; (2) The multiple filtration steps are relatively cumbersome and require special equipment, which requires a large budget cost; (3) Even after filtration, there will still be some solid matter in the liquid fertilizer, which may still cause blockage of the fertilizer delivery pipe after long-term accumulation; (4) Even if the fertilizer is transported under the transportation of a high-pressure pump, some residual fertilizer liquid or residue will still remain in the fertilizer delivery pipe. These residual fertilizer liquid or residue will cause certain corrosion to the fertilizer delivery pipe. In addition, due to the low frequency of fertilizer use and the lack of subsequent new fertilizer transportation to drive these residual liquid or residue out, these residual liquid or residue will undergo chemical changes in the pipeline, which is prone to safety hazards. At the same time, when fertilizing next time, these deteriorated residual liquid or residue will be mixed with the new fertilizer, which will also affect the quality of the new fertilizer.

[0004] In view of the above problems, it is necessary to provide a conveying system that can convey fertilizers and clean the pipeline after conveying. Summary of the invention

[0005] Purpose of the invention:

[0006] In order to overcome the problems existing in the prior art, the present invention provides a novel water-fertilizer transportation system and a working method thereof. The fertilizer transportation pipe is connected to the irrigation water pipe to share a pipe with the irrigation water, which greatly saves the cost of laying the pipe. The fertilizer transportation pipe can be directly mixed with the irrigation water to form water and fertilizer for transportation together, and the fertilizer can also be transported separately and then the water outlet pipe after the fertilizer is transported can be cleaned by the irrigation water. At the same time, the fertilizer transportation pipe can also be cleaned by the irrigation water, which is simple and convenient, and solves the problem that fertilizer is easily left in the fertilizer transportation pipe and the water outlet pipe.

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A novel water-fertilizer delivery system comprises a fertilizer storage tank, an irrigation water pipe, a fertilizer delivery pipe and a delivery assembly, wherein the fertilizer delivery pipe is arranged near the irrigation water pipe, the fertilizer delivery pipe is connected with the irrigation water pipe, the connection position between the irrigation water pipe and the fertilizer delivery pipe is arranged near the fertilizer storage tank, the irrigation water pipe comprises an outlet pipe located in the water outlet direction of the connection position and an inlet pipe located in the water inlet direction of the connection position, a first fertilizer control valve for controlling the opening and closing of the fertilizer delivery pipe is arranged at one end of the fertilizer delivery pipe near the connection position or at the connection position, a second fertilizer control valve and a cleaning water outlet are arranged at one end of the fertilizer delivery pipe near the fertilizer storage tank, the cleaning water outlet is provided with a cleaning control valve, and the cleaning water outlet is arranged on one side of the second fertilizer control valve near the connection position, and the delivery assembly comprises a first delivery assembly arranged on the outlet pipe.

[0009] The main inventive point of the present invention is to set the fertilizer delivery pipe close to the irrigation water pipe and connect it to the irrigation water pipe nearby, which greatly saves the cost of laying the pipe. It can be directly mixed with the irrigation water to form water and fertilizer for transportation together, and it can also transport the fertilizer separately and then use the irrigation water to clean the outlet pipe after transporting the fertilizer. At the same time, the irrigation water can also be used to clean the fertilizer delivery pipe, which is simple and convenient.

[0010] Preferably, the conveying assembly further includes a second conveying assembly arranged on the water inlet pipe.

[0011] Preferably, the delivery component is a high-pressure pump, because both fertilizer and irrigation water often need to be delivered over long distances, so a high-pressure pump is selected, and different models or quantities of high-pressure pumps can be selected according to the distance.

[0012] Preferably, an inlet control valve for controlling the opening and closing of the water inlet pipe is provided at one end of the water inlet pipe close to the connection position or at the connection position. The purpose of providing the inlet control valve is to be able to transport fertilizer separately. The advantage of transporting fertilizer separately is that fertilizer and water can be mixed in real time in the irrigation area and then fertilized, which is easy to operate and can avoid uneven mixing in the pipe. Because when irrigation water and fertilizer are extracted simultaneously by the first conveying component, the mixing position of the two cannot be well determined. For example, the irrigation water may reach the connection position first, which will cause the front end to be full of irrigation water, and then the concentration of fertilizer in the mixed liquid gradually increases and then remains inconvenient. In this case, the front end cannot distinguish which mixed liquids have high concentrations and which have low concentrations during irrigation, which can easily cause uneven fertilization.

[0013] Preferably, an outlet control valve for controlling the opening and closing of the outlet pipe is provided at one end of the outlet pipe close to the connection position or at the connection position, and is used in conjunction with the second conveying component. The purpose of setting the second conveying component is to more conveniently clean the fertilizer conveying pipe. If the second conveying component is not provided, only when the first conveying component conveys irrigation water, when the irrigation water flows through the connection position between the irrigation water pipe and the fertilizer conveying pipe, a part of the irrigation water flows into the fertilizer conveying pipe, thereby achieving the purpose of cleaning the fertilizer conveying pipe. However, this may result in insufficient power, resulting in limited cleaning effect. The provision of the second conveying component can increase the overall conveying power of the irrigation water pipe, and when the fertilizer conveying pipe needs to be cleaned, the outlet control valve can be closed, and then the second conveying component can be opened, and the fertilizer conveying pipe can be cleaned using the power of the second conveying component, which is more efficient, but it is necessary to provide an additional second conveying component and an outlet control valve.

[0014] Preferably, the water outlet pipe is provided with an annular spiral guide plate, which is arranged on the inner wall of the pipe body of the water outlet pipe near the connection position, and the water outlet control valve is arranged on one side of the annular spiral guide plate near the connection position, and the annular spiral guide plate is inclined toward the water outlet of the water outlet pipe. The purpose of adopting this structure is mainly to improve the mixing effect during water-fertilizer mixed transportation.

[0015] A working method of a novel water-fertilizer delivery system includes the above-mentioned water-fertilizer irrigation system, and comprises the following steps: 1) delivering fertilizer alone or delivering fertilizer and irrigation water simultaneously; 2) using irrigation water to clean the water outlet pipe; 3) using irrigation water to clean the fertilizer delivery pipe.

[0016] In step 1),

[0017] The separate fertilizer delivery includes: opening the first delivery component, the first fertilizer control valve, the second fertilizer control valve, and closing the water inlet control valve at the same time. If a water outlet control valve is provided, the water outlet control valve is opened, and the fertilizer sequentially passes through the fertilizer delivery pipe and the water outlet pipe to reach the irrigation area. After the delivery is completed, the second fertilizer control valve 54 is closed to prevent water from flowing into the fertilizer storage tank;

[0018] The simultaneous delivery of fertilizer and irrigation water includes: opening the first delivery component, the first fertilizer control valve, the second fertilizer control valve, and the water inlet control valve at the same time. If a water outlet control valve is provided, the water outlet control valve is opened, and the fertilizer and irrigation water simultaneously enter the water outlet pipe to complete mixing and reach the irrigation area. After the delivery is completed, the second fertilizer control valve 54 is closed to prevent water from flowing into the fertilizer storage tank;

[0019] Step 2) specifically includes: after the fertilizer is delivered or when irrigation is needed, the water inlet control valve is opened, and the irrigation water passes through the water inlet pipe and the water outlet pipe in sequence to reach the irrigation area, and the water outlet pipe is cleaned at the same time.

[0020] Optionally, the connection position between the fertilizer delivery pipe and the irrigation water pipe is higher than the cleaning water outlet, and step 3) specifically includes: opening the first delivery component, the first fertilizer control valve, the water inlet control valve and the cleaning control valve, closing the second fertilizer control valve, and if a water outlet control valve is provided, opening the water outlet control valve, while delivering irrigation water, a portion of the irrigation water flows from the connection position between the fertilizer delivery pipe and the irrigation water pipe to the cleaning water outlet, cleaning the fertilizer delivery pipe, and the cleaning water flows out from the cleaning water outlet. After cleaning, closing the first fertilizer control valve and the cleaning control valve.

[0021] Optionally, the conveying component also includes a second conveying component arranged on the water inlet pipe, and a water outlet control valve for controlling the opening and closing of the water outlet pipe is arranged at one end of the water outlet pipe close to the connection position or at the connection position, and step 3) specifically includes: closing the first conveying component, the water outlet control valve, and the second fertilizer control valve, opening the second conveying component, the first fertilizer control valve and the cleaning control valve, and the irrigation water cleans the fertilizer conveying pipe under the action of the second conveying component. After the cleaning water flows out from the cleaning water outlet and the cleaning is completed, the first fertilizer control valve and the cleaning control valve are closed, and the first conveying component and the water outlet control valve are opened.

[0022] Beneficial effects: Compared with the prior art, the present invention has the following advantages: by redesigning the pipeline and valve, the fertilizer delivery pipe is connected to the irrigation water pipe to share a pipeline with the irrigation water, which greatly saves the pipeline laying cost. It can be directly mixed with the irrigation water to form water and fertilizer for transportation together, and it can also transport fertilizer separately and then use irrigation water to clean the outlet pipe after transporting the fertilizer; at the same time, the fertilizer delivery pipe can also be cleaned with irrigation water, which is simple and convenient, and solves the problem of fertilizer residue in the fertilizer delivery pipe and the outlet pipe.
