Description

Technical Field

[0001] The present invention belongs to the technical field of spraying and irrigation systems, and particularly relates to a micro-spray irrigation system for integrated water and fertilizer. Background Art

[0002] In recent years, the sharp deterioration of ecological conditions such as farmland and grassland degradation has been a common problem in China. Therefore, the ecological restoration of degraded farmland and grassland has become a popular research direction. When restoring degraded farmland and grassland, irrigation is a very important link. During irrigation, it is necessary to ensure that water is fully delivered into the soil and avoid soil loss caused by excessive watering. Micro-spray irrigation is an advanced irrigation technology newly developed at home and abroad in recent years on the basis of summarizing sprinkler irrigation and drip irrigation, and can be applied to the ecological restoration of degraded farmland and grassland.

[0003] Micro-spray irrigation is an irrigation form that uses refraction-type, rotary or radiation-type micro-spray nozzles to spray water onto areas such as crop branches and leaves; micro-spray irrigation is more water-saving than sprinkler irrigation, its droplets are fine, and its adaptability is greater than that of sprinkler irrigation, and it is applicable throughout the whole process of crops from seedling stage to growth and harvest stage. It uses a low-pressure water pump and a pipeline system to convey water. Under the action of low-pressure water, through specially designed micro-atomizing nozzles, the water is sprayed into the air and dispersed into fine droplets, which are sprinkled on crop branches and leaves or on the ground under the tree crown. Micro-spray irrigation can not only increase soil moisture but also improve air humidity, playing a role in regulating the microclimate.

[0004] Currently, the commonly used micro-spray irrigation systems are usually integrated with water and fertilizer. Therefore, during sprinkler irrigation, there will be problems such as incomplete mixing of fertilizers, resulting in fertilizer sedimentation, and thus there will be errors in the water-fertilizer ratio for each sprinkler irrigation; moreover, some fertilizer particles will be mixed in the water, and thus the sprinkler heads are easily blocked. Summary of the Invention

[0005] The present invention aims to provide a micro-spray irrigation system for integrated water and fertilizer, and the present invention aims to solve the technical problems existing in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solution. A micro-spray irrigation system for integrated water and fertilizer comprises a mixing section, a diversion pipe and a sprinkler assembly connected in sequence. A fertilizer storage section and a water storage section are also connected to the mixing section. A conical material guiding cylinder is provided in the fertilizer storage section. A material guiding pipe is connected to the small-diameter end of the material guiding cylinder, and a material guiding valve is provided in the material guiding pipe. A bearing plate is also provided in the fertilizer storage section. A weight sensor is provided on the surface of the bearing plate. A controller is provided on the side wall of the fertilizer storage section. The weight sensor is electrically connected to the controller. Rotating shafts are coaxially fixed at both ends of the bearing plate. The rotating shafts penetrate through the side wall of the fertilizer storage section and are rotatably connected to the fertilizer storage section. A positioning block is fixed on the rotating shaft. A supporting block attached to the positioning block is fixed on the outer wall of the fertilizer storage section. An electromagnet is provided in the supporting block, and a magnet block is provided in the positioning block. Two control buttons for controlling the material guiding valve and the electromagnet respectively are provided in the controller. A coaxial crushing cylinder and crushing block are provided on the side of the bearing plate away from the material guiding cylinder in the fertilizer storage section. Crushing teeth are provided on the inner wall of the crushing cylinder and the outer wall of the crushing block and cooperate with each other. A driving motor for driving the crushing block to rotate is provided in the fertilizer storage section.

[0007] The beneficial effects of this technical solution: Through the cooperation of the bearing plate and the weight sensor, the fertilizer can be quantitatively weighed, achieving precise batching, improving the accuracy of the water and fertilizer ratio, and eliminating the need for manual batching. The weighed fertilizer is ground and crushed through the cooperation of the crushing teeth, which can improve the dissolution effect, reduce the fertilizer particles in the water and fertilizer, thereby improving the sprinkler irrigation efficiency and reducing the probability of blockage of the sprinkler assembly.

[0008] In another preferred embodiment of the present invention, the end of the crushing block close to the bearing plate is conical, which can achieve material guiding and prevent fertilizer from accumulating on the top of the crushing block.

[0009] In another preferred embodiment of the present invention, a material guiding plate is fixed on the outer periphery of the end of the crushing cylinder close to the bearing plate. The material guiding plate is inclined, and the end away from the crushing cylinder is fixed to the inner wall of the fertilizer storage section. The material guiding plate can facilitate the introduction of fertilizer between the crushing cylinder and the crushing block for grinding and crushing.

[0010] In another preferred embodiment of the present invention, an installation groove is provided at the end of the crushing block away from the bearing plate, and the driving motor is located in the installation groove. The installation groove can wrap the driving motor to prevent fertilizer from having an adverse effect on the driving motor.

[0011] In another preferred embodiment of the present invention, a plurality of material guiding holes are provided at the end of the fertilizer storage section fixed to the crushing cylinder, and the crushing cylinder wraps the material guiding holes. The material guiding holes can export the crushed fertilizer.

[0012] In another preferred embodiment of the present invention, a stirring shaft is rotatably connected inside the mixing part. A plurality of stirring blades are arranged on the outer periphery of the stirring shaft, and a driving member for driving the stirring shaft to rotate is further included. The rotation of the stirring shaft and the stirring blades can improve the dissolution effect of the fertilizer in water.

[0013] In another preferred embodiment of the present invention, the driving member includes a housing fixed on the mixing part. The housing communicates with the mixing part. One end of the stirring shaft is located inside the housing. A plurality of driving blades are arranged on the end of the stirring shaft located inside the housing. A driving pipe is communicated between the water storage part and the housing, and the water outlet end of the driving pipe faces the driving blades.

[0014] When water is introduced, the water impacts the driving blades, which can drive the stirring shaft to rotate, and thus stirring and mixing can be realized without additional power.

[0015] In another preferred embodiment of the present invention, a filter cylinder is arranged inside the mixing part, and the filter cylinder wraps outside the stirring shaft. The filter cylinder can filter the water fertilizer to reduce impurities and particles from entering the sprinkler irrigation assembly, and thus can reduce the blockage of the sprinkler irrigation assembly.

[0016] In another preferred embodiment of the present invention, scraping blocks are arranged on the part of the stirring shaft located inside the filter cylinder. A plurality of flexible convex blocks are arranged on the scraping blocks, and the flexible convex blocks are in contact with the inner wall of the filter cylinder. When the scraping blocks rotate, the flexible convex blocks move relative to the filter cylinder, thereby cleaning the filter cylinder and reducing the blockage of the filter cylinder.

[0017] In another preferred embodiment of the present invention, a transfer part is communicated between the mixing part and the diversion pipe.

[0018] In summary, the present invention quantitatively weighs the fertilizer, can control the water fertilizer ratio, and does not require manual proportioning. Before the fertilizer is mixed with water, it is first crushed and ground to improve the dissolution effect. When water and fertilizer are mixed, the dissolution effect is improved by the agitation of the stirring blades. When the water fertilizer is led out, it is filtered through the filter cylinder to reduce impurities and particles entering the sprinkler irrigation assembly, and thus can reduce the blockage of the sprinkler irrigation assembly. The present invention can accurately complete micro-sprinkler irrigation and has the effect of energy saving and efficiency improvement.
