Description

Technical Field

[0001] The utility model belongs to the technical field of water-fertilizer integration, and particularly relates to a water-fertilizer integration irrigation system. Background Art

[0002] Integrated fertigation (IFR) is a new agricultural technology that integrates irrigation and fertilization. Using a pressure system (or natural terrain drop), IFR combines soluble solid or liquid fertilizers, formulated according to soil nutrient content and the specific fertilizer requirements of the crop species, with irrigation water. This solution is then delivered through a controllable piping system. Once the fertilizer and water are combined, drip irrigation flows through pipes and drippers, evenly, regularly, and quantitatively irrigating the root development and growth areas of the crops, ensuring the soil around the root system remains loose and at an appropriate moisture content. IFR also designs the fertilizer solutions for different vegetable growth stages based on their specific fertilizer requirements, soil environment, nutrient content, and water and fertilizer needs during their respective growth periods. This ensures that water and nutrients are delivered directly to the crops in a timely, quantitative, and proportional manner.

[0003] For example, Chinese utility model patent CN201721397696.1 discloses an integrated water and fertilizer irrigation system, comprising a main water supply pipeline, branch pipelines, a fertilizer suction device, and an integrated water and fertilizer control system. The fertilizer suction device includes a venturi tube, a mixed fertilizer tank, a branch pipeline check valve, etc.; the integrated water and fertilizer control system includes an electric flow control valve, an electromagnetic flowmeter, a pH sensor, an EC sensor, and a programmable logic controller. This intelligent integrated water and fertilizer control system automatically adjusts the opening of the electric flow control valve based on the detected pH / EC value and the fertilizer concentration requirements of different crops, as well as the flow rate in the main water supply pipeline measured by the electromagnetic flowmeter. This changes the amount of fertilizer sucked into the venturi tube, thereby controlling the fertilizer concentration near the required level and achieving precise, intelligent, and automated water and fertilizer management.

[0004] The above-mentioned irrigation system uses a venturi tube to suck in fertilizer to mix water and fertilizer, forming a water-fertilizer mixed solution of a certain concentration. It can be seen that this irrigation system is only suitable for liquid fertilizers or easily soluble powdered fertilizers with fine particles. It cannot quickly dissolve and mix large-particle solid fertilizers, and there is a risk of clogging the irrigation system. Utility Model Content

[0005] The utility model aims to provide a water-fertilizer integrated irrigation system, in order to solve the defects of the existing water-fertilizer integrated irrigation system.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A water-fertilizer integrated irrigation system comprises a base, on which a water storage tank, a fertilizer mixing tank, a liquid pump and a booster pump are installed; a water inlet and a water pump are provided on the top of the water storage tank; the water inlet end of the water pump is connected to a first water diversion pipe, the first water diversion pipe extends into the bottom of the water storage tank, the water outlet end of the water pump is connected to a second water diversion pipe, and the second water diversion pipe is communicated with a liquid inlet provided on the top of the fertilizer mixing tank; a fertilizer adding port and a stirring motor are also provided on the top of the fertilizer mixing tank, the stirring motor is centrally arranged and fixedly connected to a stirring shaft in the fertilizer mixing tank; the liquid outlet at the bottom of the fertilizer mixing tank is communicated with the liquid inlet end of the liquid pump, the liquid outlet end of the liquid pump is connected to a pipeline filter, the other end of the pipeline filter is communicated with the liquid inlet end of the booster pump, and the other end of the booster pump is connected to an irrigation pipe network.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The irrigation device of the utility model combines irrigation and fertilization to achieve water-fertilizer integration, which solves the disadvantage that the existing irrigation system is only suitable for liquid fertilizers or fine-particle soluble powder fertilizers, and cannot quickly dissolve and mix large-particle solid fertilizers. It has high irrigation efficiency, is not easy to clog, and can effectively save water and fertilizer.

[0010] 2. By installing a filter in the irrigation pipeline, the blockage of the dripper or sprinkler can be effectively prevented. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The present invention will be further explained below with reference to the accompanying drawings.

[0015] like Figure 1-2As shown, a water-fertilizer integrated irrigation system includes a base 1, on which a water storage tank 2, a fertilizer mixing tank 5, a liquid pump 7 and a booster pump 9 are installed. A water inlet 14 and a water pump 4 are provided on the top of the water storage tank 2. The water inlet end of the water pump 4 is connected to a first water diversion pipe 3, which extends into the bottom of the water storage tank 2. The water outlet end of the water pump 4 is connected to a second water diversion pipe 17, which is connected to the liquid inlet provided on the top of the fertilizer mixing tank 5; the top of the fertilizer mixing tank 5 is also provided with a A fertilizer adding port 15 and a stirring motor 16 are provided, and the stirring motor 16 is centrally arranged and fixedly connected to the stirring shaft 6 in the mixing box 5; a fertilizer screen 18 is also installed inside the mixing box 5, and a plurality of water-permeable holes are provided at the bottom and around the fertilizer screen 18; the liquid outlet at the bottom of the mixing box 5 is connected to the liquid inlet end of the liquid pump 7, and the liquid outlet end of the liquid pump 7 is connected to the pipeline filter 8, and the other end of the pipeline filter 8 is connected to the liquid inlet end of the booster pump 9, and the other end of the booster pump 9 is connected to the irrigation pipe network.

[0016] The irrigation network includes an irrigation main pipe 10, a water distribution pipe 12 and an irrigation branch pipe 11. One end of the irrigation main pipe 10 is connected to the booster pump 9, and the other end is connected to the water distribution pipe 12. The other end of the water distribution pipe 12 is connected to multiple irrigation branch pipes 11, and each irrigation branch pipe 11 is provided with multiple drip nozzles 13.

[0017] The working process of this utility model is as follows:

[0018] First, open the water inlet 14 and fill the water storage tank 2 with water. After it is filled, according to the calculated water-fertilizer ratio, first put the soluble fertilizer into the mixing box 5 through the fertilizer adding port 15 on the top of the mixing box 5. The fertilizer particles are accumulated on the fertilizer screen 18 under the action of gravity. Then, water is added to the mixing box 5 through the water pump. While the water is entering, the fertilizer particles accumulated on the fertilizer screen 18 are flushed, so that they are quickly dissolved in the clean water. The bottom and side of the fertilizer screen 18 are provided with sieve holes with an aperture of 1 to 5 mm, which can filter out the larger and less soluble fertilizer particles without blocking the water inflow, thereby preventing the fertilizer particles from clogging the liquid pump 7. When more water is entering, the stirring motor 16 can be turned on to drive the stirring shaft 6 to rotate, and the stirring blades fixed on the stirring shaft 6 are used to stir the mixed fertilizer. The solution in the box 5 accelerates the dissolution rate of the fertilizer and ensures that the water and fertilizer are mixed evenly; at the same time, the bottom of the fertilizer screen 18 does not overlap with the bottom of the fertilizer mixing box 5, which can ensure that the turbulence generated by the stirring always flushes the fertilizer particles and does not form fertilizer precipitation at the bottom; after the water and fertilizer are mixed evenly, turn on the liquid pump 7 to pump the water and fertilizer solution into the pipeline filter 8, and use the pipeline filter 8 to filter the impurity particles and possible fertilizer particles in the pipeline. The filtered water and fertilizer solution is pumped into the irrigation main 10 through the booster pump 9, and then evenly distributed to each irrigation branch pipe 11 through the water distribution pipe 12. Finally, it is evenly sprayed into the farmland through the drip nozzle 13 arranged at the bottom of each irrigation branch pipe 11, and fertilization is completed while irrigation is completed, so as to achieve the purpose of water and fertilizer integration while saving water.

[0019] In the above working process, the water storage tank 2 and the fertilizer mixing tank 5 are made of transparent plastic for easy observation of the liquid level; the water pumps and motor control can be controlled by a PLC controller for auxiliary control, which is not limited here.

[0020] In addition, a large amount of water resources will be used in agricultural irrigation, and sometimes impurity-containing secondary water sources will be used for water saving. Therefore, to avoid blockage, a water distribution plate 19 is vertically arranged in the middle of the water storage tank 2, and a screen is arranged on the top of the water distribution plate 19. A sewage outlet 20 is arranged on the same side of the bottom of the water storage tank 2 as the water inlet 14.

[0021] When the secondary water (such as rainwater) enters the water storage tank 2 from the water inlet 14, it will first overflow and deposit on the left side of the water distribution plate 19. The large-particle impurities are deposited at the bottom of the water storage tank 2, and the supernatant flows into the right side of the water distribution plate 19 through the overflow port on the top of the water distribution plate, and the density of the floating impurities (such as tree leaf fragments) is smaller, which will be blocked by the filter screen installed on the overflow port on the left side of the water distribution plate 19, so as to avoid entering the first water inlet pipe 3 and blocking the water pump 4. When the water in the water storage tank 2 is used up, the sewage outlet 20 at the bottom of the water storage tank 2 can be opened for sewage cleaning.

[0022] The above has not been described, which uses the same function or effect of the existing technology to achieve the same function or effect.
